通过C＃值的JavaScript [英] Pass C# Values To Javascript

问题描述

在装载我想一个值从服务器端变量传递给我的javascript功能的页面。

On loading the page I want to pass a value to my javascript function from a server side variable.

我似乎无法得到它的工作，这是我有：

I cannot seem to get it to work this is what I have:

Asp.Net

protected void Page_Load(object sender, EventArgs e)
{
    string blah="ER432";
}

的JavaScript

Javascript

<script type="text/javascript">

    var JavascriptBlah = '<%=blah%>';

    initObject.backg.product_line = JavascriptBlah;

</script>

添加此页面

 public string blah { get; set; }


        protected void Page_Load(object sender, EventArgs e)
        {
           blah="ER432";
        }

我还是我得到一个错误：
CS0103：名称'嗒嗒'不在当前上下文中存在

I still am getting an error: CS0103: The name 'blah' does not exist in the current context

我也想尝试做到这一点，而无需使用hdden领域

Also I would like to try and accomplish this without using hdden fields

推荐答案

我相信你的C＃变量必须以这个类成员。尝试在类级别，而不是 Page_Load中的局部变量声明它（）。曾经的Page_Load完成它显然失去范围。

I believe your C# variable must be a class member in order to this. Try declaring it at the class level instead of a local variable of Page_Load(). It obviously loses scope once page_load is finished.

public partial class Example : System.Web.UI.Page
{
    protected string blah;

    protected void Page_Load(object sender, EventArgs e)
    {
        blah = "ER432";
        //....
