I have problem with the ajax post url it keep go to difference url path i have a few web service but all in the folder but somehow it keep go to the wrong folder i even try difference folder or just put at the default without any folder it still the same If this is an issue with jQuery, we need a test case that reproduces the issue. For the front-end, we’ll need to make a few changes. But look at what happens when we try to return a List of strings: Oops. What follows is a detailed explained of what you need to do to make the AJAX requests work. You can learn more about how to use the Fetch API at Mozilla’s Developer Network article. Here’s a quick reference for all the techniques we’ve discussed in this article.

Run your application to test it out. Next, add the following two controller action methods. There’s nothing “wrong” or “bad” about using them. You can see this in your POST above. If you still are interested in pursuing this issue, feel free to add a comment with the requested information and we will be happy to reopen the ticket if it is still valid.

If you navigate to http://localhost:YOURPORT/SwearJar you should see something like the following: Let’s make it a little less boring and get it ready to make AJAX calls. For something like this, we’ll need to return our data as JSON. It’s also possible to just hard-code this as “/SwearJar/GetAmount”, which is what gets rendered to the page anyway. When you use the Ajax call in ASP.NET MVC, you just can return a JSON object but not a file, if you want to do that, you need to create and save the file in server and return it's path to Ajax, after that, you can call a redirect link for download the file, because this is a temp file, … And we have found three solutions for that Solutions to get relative URL 1. You may have seen more verbose GET syntax for jQuery before, using $.ajax(), like this: There’s nothing stopping you from using this, but $.get() abstracts a lot of the configuration away. Not used the relative path. Tried a lot of different things to fix this, and found that using "POST" will allow the code to run correctly.

So, instead of passing the value in jQuery, you need to create an object with the name of the form value: Test it out!

AJAX controller methods are great for one-of-a-kind functionalities and one-off use cases. The server won’t know what to do with this, and it won’t bind to the id variable in the back end. This is really helpful if you already have the class written and are using it elsewhere. The code works fine in an MVC applications without Areas. Ready to stop wasting time and money on learning resources that don’t work? Once you get your mind wrapped around the Model-View-Controller pattern, working with those areas in the application feels comfortable. Notice especially the second parameter in the return line, JsonRequestBehavior.AllowGet. Among other things, Web API helps to simplify some of the coding. I may receive a commission for purchases made through these links. Next, we use jQuery to call the controller method. By default, jQuery comes bundled with new ASP.NET projects. We’ll start with something stupidly simple.

In our controller, add the following two methods: Notice the HttpPost attribute, as well as the amount parameter in the method signature. I can’t tell you how many times I’ve had this be the tiny error that makes me waste half an hour. Web API. Once the data is returned from the controller, we’ll display it in the swearJar div.

Instinctively, you might have tried something like this: But this will give you an error. Furthermore, .NET has some quirks that aren’t really obvious. You need to either nix the leading slash, or you need to append the application name to the front of the url value.

Setting up a new ASP.NET MVC project with controllers and views is pretty straightforward, with comprehensive examples on the official site.

Because we get so many tickets, we often need to return them to the initial reporter for more information. Stop wasting your time and start getting things done. We’ve also changed the jQuery $.get method to $.post.

The following example is functionally equivalent to the example we just looked at. $.ajax({url: '/Sale/getCustomerId', type: "POST", async: false

Let’s now turn to the Javascript code in our view.

While this is attractive in some applications, adding AJAX functionality adds an additional layer of complexity that ends up getting some new (and old) developers stuck. If you’re just looking for a quick reference, jump to the summary.

Since we’re sending data to the server and updating our total, POST is appropriate, whereas GET is not. In your project, go to Views -> SwearJar -> Index.cshtml.

When passing in an MVC path with a specified area (/Area/Controller/Action) to the ajax method there is an issue with using a "GET". As long as it’s working, I prefer to use $.get().

As mentioned in the comments, you’d want to persist this to a database in a real application. Place ajax calls in View Page We need to define all Ajax calls in the view page itself and get the relative URL by using @Url.Action("",""), method When you have that leading slash in there, which is what Url.Action is doing, it tells the server to look in its root, not the application's root.

Next, once the project has been created, add a new controller by right-clicking on the Controllers folder and selecting Add -> Controller…. To make this happen in our controller, we need to make some adjustments to the Action method.
Think of it as you "get to" POST to whatever URL you like. With Fetch, a GET request looks like this: Using Fetch is not absolutely necessary, but should be something that you consider, especially if you’re not using jQuery elsewhere in your project. If you’re interested in learning more about Web API, Microsoft has a great tutorial describing the basics. Perhaps you are posting to an action that returns a partial view's HTML result and the result is used to update the current page. Inside of getAmount, we retrieve the URL of our controller method by using the Url.Action HTML helper. This will accept a double and add it to the current amount, returning the new amount of money in the swear jar. Add the parameters to the method signature, like this: You could also use a class as the single parameter for the method. If we wanted to make a GET call with more than one parameter, that’s as easy as adding parameters to the method signature.

This will be a good way to see how simple data types are used in AJAX controller methods. Hi Guys. Visual Studio automatically includes jQuery on the Shared/_Layout.cshtml page, so every View ought to be able to access it already.

Tried a lot of different things to fix this, and found that using "POST" will allow the code to run correctly. On the front end, all you’d have to do is create the form fields and add the form values to the data object when you make the AJAX call. In the SwearJar controller, add this method: Then, over in your Index.cshtml file, add this Javascript code inside the script tags. Bootstrap also requires the library. Create an Action for generate the Excel, 3.

AJAX provides the option of updating parts of your web page without reloading the entire page.

We’ll click a button, and our page will tell us how much money is in the swear jar.

Your email address will not be published. Your email address will not be published. You could also use an object as the single parameter in the method signature. Thanks!

As with the $.get method, notice that I’m passing a data object to the $.post method. If you see this error, it means you’re missing the JsonRequestBehavior parameter: Once you add it back in, you’ll be able to see your data just fine.

If you’re getting a 500 error when you try to query your action, make sure you have that flag set. When you use the Ajax call in ASP.NET MVC, you just can return a JSON object but not a file, if you want to do that, you need to create and save the file in server and return it’s path to Ajax, after that, you can call a redirect link for download the file, because this is a temp file, so you should need to delete it after download. The second will be the AJAX method to find a person by his or her ID. But if you’re not using jQuery or Bootstrap, you might want to consider using Fetch, the native Javascript implementation of HTTP requests, no libraries needed. The return type needs to be JsonResult and we need to serialize our data to the JSON format. The syntax is very simple. Run the project, and click on the button. Inside the Views folder, Right-click on the SwearJar folder. When I’m trying to learn something, I try to work with examples that are as close to real-life as possible, without being too complicated. We’ll begin simply, by creating a method in the controller to return the amount that’s in the swear jar.

Its because your ajax call is running async. The below demo code just for create and download an Excel file: 1. (This would normally be done with a database).

First, the client side code. Bootstrap for .NET Devs is the up-to-date, in-depth guide to ASP.NET and Bootstrap 4. The following code doesn’t work, and will result in an error: This won’t bind to the variable in the back end. In this section, let’s tell our MVC Controller action how much we’re putting into the jar, and have the button represent the action of putting the money in. A simple AJAX-infused app might be something like a to-do list, grocery list, or a list of social media posts.

Since we’re using jQuery to make these AJAX requests, we’ll obviously need to include jQuery. We need to auto delete the file after download, so need to create an Action Filter, Introduction Crystal reports is a best way for show reports in project and it’s also free, so, Please find my new website in here Introduction If you want to develop a web application which, I just want to mark that how to upgrading mysql in CWP, and below content are from here. Otherwise, we would need to do that ourselves, like this: Next, I’m going to set up the view with our HTML elements. Select Add -> View and make the Index view. To make our output look a little better, change the line inside the jQuery $.get callback to: Then try running the project again and clicking on the button.

Now that we have our controller, we just need to create an Index view to house our client-side markup and JavaScript. CDN provided by MaxCDN, Passing MVC path with an Area as URL in .ajax(). Hosting provided by Media Temple

Now let’s change up our front-end code. Select the MVC 5 Controller – Empty option, and call this controller SwearJar. Clear out the existing Razor markup, and replace it with this.

Don't think of it as you "need to". We’ll have an input to set the amount of money to be added to the jar each time.

If you navigate to http://localhost:YOURPORT/SwearJar you should see something like the following: Let’s make it a little less boring and get it ready to make AJAX calls. For something like this, we’ll need to return our data as JSON. It’s also possible to just hard-code this as “/SwearJar/GetAmount”, which is what gets rendered to the page anyway. When you use the Ajax call in ASP.NET MVC, you just can return a JSON object but not a file, if you want to do that, you need to create and save the file in server and return it's path to Ajax, after that, you can call a redirect link for download the file, because this is a temp file, … And we have found three solutions for that Solutions to get relative URL 1. You may have seen more verbose GET syntax for jQuery before, using $.ajax(), like this: There’s nothing stopping you from using this, but $.get() abstracts a lot of the configuration away. Not used the relative path. Tried a lot of different things to fix this, and found that using "POST" will allow the code to run correctly.

So, instead of passing the value in jQuery, you need to create an object with the name of the form value: Test it out!

AJAX controller methods are great for one-of-a-kind functionalities and one-off use cases. The server won’t know what to do with this, and it won’t bind to the id variable in the back end. This is really helpful if you already have the class written and are using it elsewhere. The code works fine in an MVC applications without Areas. Ready to stop wasting time and money on learning resources that don’t work? Once you get your mind wrapped around the Model-View-Controller pattern, working with those areas in the application feels comfortable. Notice especially the second parameter in the return line, JsonRequestBehavior.AllowGet. Among other things, Web API helps to simplify some of the coding. I may receive a commission for purchases made through these links. Next, we use jQuery to call the controller method. By default, jQuery comes bundled with new ASP.NET projects. We’ll start with something stupidly simple.

In our controller, add the following two methods: Notice the HttpPost attribute, as well as the amount parameter in the method signature. I can’t tell you how many times I’ve had this be the tiny error that makes me waste half an hour. Web API. Once the data is returned from the controller, we’ll display it in the swearJar div.

Instinctively, you might have tried something like this: But this will give you an error. Furthermore, .NET has some quirks that aren’t really obvious. You need to either nix the leading slash, or you need to append the application name to the front of the url value.

Setting up a new ASP.NET MVC project with controllers and views is pretty straightforward, with comprehensive examples on the official site.

Because we get so many tickets, we often need to return them to the initial reporter for more information. Stop wasting your time and start getting things done. We’ve also changed the jQuery $.get method to $.post.

The following example is functionally equivalent to the example we just looked at. $.ajax({url: '/Sale/getCustomerId', type: "POST", async: false

Let’s now turn to the Javascript code in our view.

While this is attractive in some applications, adding AJAX functionality adds an additional layer of complexity that ends up getting some new (and old) developers stuck. If you’re just looking for a quick reference, jump to the summary.

Since we’re sending data to the server and updating our total, POST is appropriate, whereas GET is not. In your project, go to Views -> SwearJar -> Index.cshtml.

When passing in an MVC path with a specified area (/Area/Controller/Action) to the ajax method there is an issue with using a "GET". As long as it’s working, I prefer to use $.get().

As mentioned in the comments, you’d want to persist this to a database in a real application. Place ajax calls in View Page We need to define all Ajax calls in the view page itself and get the relative URL by using @Url.Action("",""), method When you have that leading slash in there, which is what Url.Action is doing, it tells the server to look in its root, not the application's root.

Next, once the project has been created, add a new controller by right-clicking on the Controllers folder and selecting Add -> Controller…. To make this happen in our controller, we need to make some adjustments to the Action method.
Think of it as you "get to" POST to whatever URL you like. With Fetch, a GET request looks like this: Using Fetch is not absolutely necessary, but should be something that you consider, especially if you’re not using jQuery elsewhere in your project. If you’re interested in learning more about Web API, Microsoft has a great tutorial describing the basics. Perhaps you are posting to an action that returns a partial view's HTML result and the result is used to update the current page. Inside of getAmount, we retrieve the URL of our controller method by using the Url.Action HTML helper. This will accept a double and add it to the current amount, returning the new amount of money in the swear jar. Add the parameters to the method signature, like this: You could also use a class as the single parameter for the method. If we wanted to make a GET call with more than one parameter, that’s as easy as adding parameters to the method signature.

This will be a good way to see how simple data types are used in AJAX controller methods. Hi Guys. Visual Studio automatically includes jQuery on the Shared/_Layout.cshtml page, so every View ought to be able to access it already.

Tried a lot of different things to fix this, and found that using "POST" will allow the code to run correctly. On the front end, all you’d have to do is create the form fields and add the form values to the data object when you make the AJAX call. In the SwearJar controller, add this method: Then, over in your Index.cshtml file, add this Javascript code inside the script tags. Bootstrap also requires the library. Create an Action for generate the Excel, 3.

AJAX provides the option of updating parts of your web page without reloading the entire page.

We’ll click a button, and our page will tell us how much money is in the swear jar.

Your email address will not be published. Your email address will not be published. You could also use an object as the single parameter in the method signature. Thanks!

As with the $.get method, notice that I’m passing a data object to the $.post method. If you see this error, it means you’re missing the JsonRequestBehavior parameter: Once you add it back in, you’ll be able to see your data just fine.

If you’re getting a 500 error when you try to query your action, make sure you have that flag set. When you use the Ajax call in ASP.NET MVC, you just can return a JSON object but not a file, if you want to do that, you need to create and save the file in server and return it’s path to Ajax, after that, you can call a redirect link for download the file, because this is a temp file, so you should need to delete it after download. The second will be the AJAX method to find a person by his or her ID. But if you’re not using jQuery or Bootstrap, you might want to consider using Fetch, the native Javascript implementation of HTTP requests, no libraries needed. The return type needs to be JsonResult and we need to serialize our data to the JSON format. The syntax is very simple. Run the project, and click on the button. Inside the Views folder, Right-click on the SwearJar folder. When I’m trying to learn something, I try to work with examples that are as close to real-life as possible, without being too complicated. We’ll begin simply, by creating a method in the controller to return the amount that’s in the swear jar.

Its because your ajax call is running async. The below demo code just for create and download an Excel file: 1. (This would normally be done with a database).

First, the client side code. Bootstrap for .NET Devs is the up-to-date, in-depth guide to ASP.NET and Bootstrap 4. The following code doesn’t work, and will result in an error: This won’t bind to the variable in the back end. In this section, let’s tell our MVC Controller action how much we’re putting into the jar, and have the button represent the action of putting the money in. A simple AJAX-infused app might be something like a to-do list, grocery list, or a list of social media posts.
