How to Call Controller Actions using JQuery in ASP NET MVC

Question

I ve been reading on this for a while and found that you can call a controller action by using     ajax  MyController MyAction   function data        alert data         Does this mean I should add the MicrosoftMvcAjax js or the MicrosoftAjax js along with the Jquery lib   Also  what should the second parameter contain in the   ajax   function   Lastly  any other link in stackoverflow or outside of the site that could be helpful in asp net mvc w  ajax and jquery   Thanks

In response to the above post I think it needs this line instead of your line:-

var strMethodUrl = '@Url.Action("SubMenu_Click", "Logging")?param1='+value1+' &param2='+value2

Or else you send the actual strings value1 and value2 to the controller.

However, for me, it only calls the controller once. It seems to hit 'receieveResponse' each time, but a break point on the controller method shows it is only hit 1st time until a page refresh.

Here is a working solution. For the cshtml page:-

   <button type="button" onclick="ButtonClick();"> Call &raquo;</button>

<script>
    function ButtonClick()
    {
        callControllerMethod2("1", "2");
    }
    function callControllerMethod2(value1, value2)
    {
        var response = null;
        $.ajax({
            async: true,
            url: "Logging/SubMenu_Click?param1=" + value1 + " &param2=" + value2,
            cache: false,
            dataType: "json",
            success: function (data) { receiveResponse(data); }
        });
    }
    function receiveResponse(response)
    {
        if (response != null)
        {
            for (var i = 0; i < response.length; i++)
            {
                alert(response[i].Data);
            }
        }
    }
</script>

And for the controller:-

public class A
{
    public string Id { get; set; }
    public string Data { get; set; }

}
public JsonResult SubMenu_Click(string param1, string param2)
{
    A[] arr = new A[] {new A(){ Id = "1", Data = DateTime.Now.Millisecond.ToString() } };
    return Json(arr , JsonRequestBehavior.AllowGet);
}

You can see the time changing each time it is called, so there is no caching of the values...

You can start reading from here jQuery ajax    Actually Controller Action is a public method which can be accessed through Url   So any call of an Action from an Ajax call  either MicrosoftMvcAjax or jQuery can be made   For me  jQuery is the simplest one   It got a lots of examples in the link I gave above   The typical example for an ajax call is like this     ajax          edit to add steve s suggestion        url    ControllerName ActionName       url    lt    Url Action  ActionName    ControllerName     gt        success  function data                your data could be a View or Json or what ever you returned in your action method              parse your data here          alert data               More examples can be found in here

the previous response is ASP NET only   you need a reference to jquery  perhaps from a CDN    http   ajax aspnetcdn com ajax jQuery jquery-1 5 1 js  and then a similar block of code but simpler        ajax   url    Controller Action Id            success  function data    alert data                statusCode                  404  function content    alert  cannot find resource                    500  function content    alert  internal server error                            error  function req  status  errorObj                      handle status      timeout                    handle other errors                  I ve added some necessary handlers  404 and 500 happen all the time if you are debugging code   Also  a lot of other errors  such as timeout  will filter out through the error handler   ASP NET MVC Controllers handle requests  so you just need to request the correct URL and the controller will pick it up   This code sample with work in environments other than ASP NET

We can call Controller method using Javascript   Jquery very easily as follows    Suppose following is the Controller method to be called returning an array of some class objects  Let the class is  A   public JsonResult SubMenu Click string param1  string param2                A   arr   null          try                       Processing               Get Result and fill arr                     catch               return Json arr   JsonRequestBehavior AllowGet            Following is the complex type  class    public class A       public string property1  get   set       public string property2  get   set          Now it was turn to call above controller method by JQUERY  Following is the Jquery function to call the controller method   function callControllerMethod value1   value2        var strMethodUrl     Url Action  SubMenu Click    Home   param1 value1  amp param2 value2        getJSON strMethodUrl  receieveResponse       function receieveResponse response         if  response    null            for  var i   0  i  lt  response length  i                 alert response i  property1                       In the above Jquery function  callControllerMethod  we develop controller method url  and put that in a variable named  strMehodUrl  and call getJSON method of Jquery API   receieveResponse is the callback function receiving the response or return value of the controllers method    Here we made use of JSON   since we can t make use of the C  class object  directly into the javascript function   so we converted the result  arr  in controller method into JSON object as follows   Json arr   JsonRequestBehavior AllowGet     and returned that Json object   Now in callback function of the Javascript   JQuery we can make use of this resultant JSON object and work accordingly to show response data on UI   For more detaill  click here
