如何在ASP.Net MVC中通过HTML调用C＃函数 [英] How do I call a C# Function by HTML in ASP.Net MVC

问题描述

大家好，

我有一个使用HMTL创建的按钮。我想要点击这个按钮来调用我用c＃编码的消息。



我的c＃函数生成随机数，点击时我想要HTML中的这个按钮显示生成的数字。



C＃代码：

Hi guys,
I have got a button that is created I created using HMTL. I want when this button is clicked to call a message that i have coded using c#.

My c# function generates random numbers, and I want this button in HTML when clicked to display the generated number.

C# Code:

public class HomeController : Controller
   {
     private  static Random rand = new Random();
     private string _randomnumber;



       public ActionResult Index()
       {

           for (int i = 0; i < 2; i++)
           {
             _randomnumber= (Convert.ToString(rand.Next(1000, 9900)));
              return new JsonResult { Data = _randomnumber, JsonRequestBehavior = JsonRequestBehavior.AllowGet };


           }

           return View();

       }

HTML代码：

HTML Code:

<input type ="button" onclick=" GetMessage() " value=" Get Message"/>
        <p></p>
        <script src="//ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>
        <script>
            function GetMessage() {

                $.get("/{HomeControlle}r/{Index}", function(data) {
                    $("p").html(data);
                });
            }


        </script>

当我运行这个应用程序，按钮不显示，浏览器只显示生成的数字。有人可以帮忙吗？

When I run this application, the button does not show, the browser only shows the generated number. Can someone please help?

推荐答案

.get（/ {HomeControlle} r / {Index}，function（data）{

.get("/{HomeControlle}r/{Index}", function(data) {

（p）。html（data）;
}）;
}


< / script < span class =code-keyword>>

("p").html(data); }); } </script>

试试这个

try this

public class HomeController : Controller
   {
     private  static Random rand = new Random();
     private string _randomnumber;



       public ActionResult Index()
       {
           return View();

       }

public int Random()
{
for (int i = 0; i < 2; i++)
           {
             _randomnumber= (Convert.ToString(rand.Next(1000, 9900)));
              return new JsonResult { Data = _randomnumber, JsonRequestBehavior = JsonRequestBehavior.AllowGet };


           }
return _randomnumber;
}

<input type ="button" onclick=" GetMessage() " value=" Get Message"/>
        <p></p>
        <script src="//ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>
        <script>
            function GetMessage() {
