MVC3 Calling controller method from Javascript

asp.net-mvc-3, javascript

Solution

Make an ajax call to your controller action method. You may use `$.get` method like below.

$(function(){
   $(document).on("click", ".open-DeleteRowDialog", function () { 
      var pwd="";
       $.get("@Url.Action("Yourcontroller","GeneratePsw")",function(data){
           pwd=data;
           //now do whatever you want with pwd variable;
       });    
    })
 });

$.get is a short form of `$.ajax` method with type HTTP GET.

If you have trouble like cached data in the response, you may add a unique timestamp in your `get` call so that you won't get the cached result. You may use $.now method.

 $.get("@Url.Action("Yourcontroller","GeneratePsw")?"+$.now(),function(data){
    // to do : do something with result
 });

Another way is to set the cache property value to false in ajaxSetup method. But this will be applicable to all ajax calls.

Problem

In MVC3. I have a button class"open-deleteRowDialog" when i click on it goes to this javascript: ``` $(document).on("click", ".open-DeleteRowDialog", function () { var pwd= '@Url.("GeneratePsw","Admin")'; $(".modal-body #pwd").val(pwd); $('#1').modal('show'); }) ``` what i want is to call a method (in controller), who has to return a string, that´s what i want to save in "var pwd" to show in a model (view) the method (in controller) is: ``` public string GeneratePsw() { HomeBridgeEntities ddbb = new HomeBridgeEntities(); SqlConnection Cn = new SqlConnection(((System.Data.EntityClient.EntityConnection)ddbb.Connection).StoreConnection.ConnectionString); SupPassGenerator sup = new SupPassGenerator(Cn); //psw conteins a password from CreateRandomPassword string psw = sup.CreateRandomPassword(9); return psw; } ``` thank you!
