在我看来，我有一个名为变量如下图所示X：

@{ int x;} 

我想从内部设定的值X我的jQuery代码。

我该怎么办？

Answer 1

本：

@{var x = 5;} 

<script type="text/javascript"> 
    var c= @(x); 
    alert(c); 
</script> 

Answer 2

只需使用@x来获取值。防爆。

@{int x = 42;} 

<script type="text/javascript"> var x = @(x); alert('The answer to the Ultimate Question of Life, the Universe, and Everything is ' + x); </script> 

Answer 3

你可以做这样的事情...

@{ // declare this in your view 
    int x = 100; 
} 

    $(document).ready(function() { 

    var postdata = @x + 100; // here is the updated code. if you want to change the value eg. this will alert 200 
    alert(postdata); 
    $.ajax({ 
      url: 'Home/Index', 
      data: postdata, 
      success: function (returnData) { 
       alert(returnData); // this will alert 210 
      } 
     }); 
}); 

控制器

public ActionResult Index(int x) // x will get the value here which is 200 here now.. 
{ 
    var y = x + 10; // do some logic here with the posted data from your view 
    return Json(y,JsonRequestBehaviour.AllowGet); // you will need to return Json here cos you using the AJAX call 
}
