从代码隐藏中获取C＃变量到aspx页面上的javascript变量 [英] Get C# variable from codebehind into javascript variable on aspx page

问题描述

我是c＃和asp.net的初学者。我的代码后面有一个公共十进制变量。如何使用这个变量并在我的aspx页面上使用javascript的if语句中使用它？...任何帮助将不胜感激。

Hi, i am beginner at c# and asp.net. I have a public decimal variable on in my code behind. How do iget this variable and use it in a if statement with javascript on my aspx page?...Any help will be much appreciated.

推荐答案

那么有一个我们以前在ASP时使用的快捷方式，这仍然适用于ASP.NET

在页面中的codebehind声明一个公共属性说public int MyInteger

在aspx中放这个

Well there is one shortcut we used to use during the ASP days, this still works in ASP.NET
In the page codebehind declare a public property say public int MyInteger
In the aspx put this

<script>
    function GetMyValue()
    {
     var someVar = <%=this.MyInteger%>;
     //Do something
    }
</script>

为了做得好，你可以使用RegisterClientScriptBlock [ ^ ]

To do it nicely, you can use RegisterClientScriptBlock [^]

string script = string.Format("var myVariable = '{0}';", vaiable.ToString());
if (!ClientScript.IsClientScriptBlockRegistered("myScript"))
{
    ClientScript.RegisterClientScriptBlock(typeof(_Default), "myScript", script, true);
}

public decimal Price;

然后你就可以从Javascript访问它了

then you can access that from Javascript as

var price = <%=this.Price%>;

public int i;

i = 10;

//做一些代码....




查看页面上的
....

用jquery函数或任何写入事件

var price =<％= this.i％>;

public int i;
i=10;
//do some code....


on view page....
write with in jquery function or any event
var price = <%=this.i%>;
