尝试从javascript访问服务器端变量

i have a page where in the form load i initialize a server side variable with value and i want to render that value in js section. i am working with asp.net webform apps.

我有一个页面，在这个页面中，我用value初始化一个服务器端变量，我想在js部分中呈现这个值。我正在使用asp.net webform应用程序。

my server side page load code

 string errblankEmail ="";
 protected void Page_Load(object sender, EventArgs e)
 {
    errblankEmail ="Hello World";
 }

if (str == '') {
  alert('<% =errblankEmail %>');
}

when i run the page then i am getting error message like CS0103: The name 'errblankEmail' does not exist in the current context

当我运行这个页面时，我就会收到像CS0103这样的错误消息:在当前上下文中不存在“errblankEmail”这个名称

and i also saw that my page_load is not getting called because i set break point there. so guide me how to fix this problem. thanks

我还看到page_load没有被调用，因为我在那里设置了断点。所以指导我如何解决这个问题。谢谢

You have to make the variable public in order to access it.

为了访问变量，必须将其公开。

public string errblankEmail ="";
