将ASP.NET变量分配给Javascript变量 [英] Assign an ASP.NET variable to a Javascript Variable

问题描述

你好，

我的代码中有以下内容

Hi there,

I have the following in my codeBehind

Public Property MenuType as String = "Hello"

在我的JavaScript中，我有:

In my javascript I have:

$(document).ready
(function () {
    //If the MenuType is hide then we want to remove the menu from the iPhone, 
    //but leave it there for the desktop version. The MenuType is defined in the asp.net page
    var menuType = "<%=MenuType%>";
    alert(menuType);
}
);

加载页面时，出现<％= MenuType％>警报. -也就是说，我得到的是文字表达式，而不是变量的值.

我研究的所有信息都使我相信上述方法应该有效.我在做什么错?

When I load the page I get the alert <%=MenuType%> - that is I get the literal expression rather than the value of the variable.

The information I have researched all leads me to believe that the above should work. What am I doing wrong?

推荐答案

(document).ready (功能 () { // 如果MenuType为hide，那么我们要从iPhone中删除菜单， // ，但将其保留在台式机版本中. MenuType在asp.net页中定义 var menuType = " ; alert(menuType); } );

(document).ready (function () { //If the MenuType is hide then we want to remove the menu from the iPhone, //but leave it there for the desktop version. The MenuType is defined in the asp.net page var menuType = "<%=MenuType%>"; alert(menuType); } );

加载页面时，出现<％= MenuType％>警报. -也就是说，我得到的是文字表达式，而不是变量的值.

尝试这样..

Hi,

try like this..

//Javascript Function
function AssignValue(Value)
{
    var menuType = Value;
    alert(menuType);
}

并将值从后面的代码传递给函数

and pass the value to the function from code behind

ScriptManager.RegisterClientScriptBlock(this.Page,this.GetType(),"Myscript","AssignValue('"+ MenuType +"');",true);
