MVC3从JavaScript调用控制器方法 [英] MVC3 Calling controller method from Javascript

问题描述

在MVC3。我有一个按钮类开放式deleteRowDialog当我点击它进入这个JavaScript：

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');

})

我想是调用一个方法（在控制器），谁拥有返回一个字符串，that's我想要的VAR PWD保存在一个模型来显示（视图）

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)

（在控制器）的方法是：

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;


        }

谢谢！

推荐答案

请在 AJAX 拨打你的控制器的操作方法。您可以使用 $。获得法像下面。

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;
       });    
    })
 });

$不用彷徨是 $。阿贾克斯法类型HTTP GET。

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

如果你有一个像在响应缓存数据的麻烦，你可能在你的 GET 调用添加了独特的时间戳，这样你就不会获得缓存的结果。您可以使用 $。现在方法。

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
 });

另一种方法是设置 ajaxSetup 方法缓存属性值设置为false。但是，这将适用于所有的Ajax调用。

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