使用JavaScript从ascx页面调用ascx.cs方法

Question

I have a code behind file which contains a method:

public string ProductsAsJson()

which returns a json representation of a series of products. I want to be able to use some angular functions in my ascx page and so I am trying to call the function using:

 <script type="text/javascript">

   var products = <%# ProductsAsJson() %>;

but it is failing to retrieve the list of products.

What am I a doing wrong?

Answer 1

您可以将ProductsAsJson（）的返回值存储在公共变量中，并在.cs页面加载时调用此方法，并在ascx控件中访问变量的值并分配给javascript变量。

var products = <%# ProductsAsJson %>;
