我如何使用JavaScript将值设置为ASP隐藏字段 [英] How can i set value to asp hidden field using javascript

问题描述

HI，

我有一个ASP隐藏字段，我需要使用JavaScript设置一个值.而且此javascript不在网页中的js文件中.

我将js包含在此网页中


当我使用下面的代码时，它不起作用.

I have a asp hidden field, and i need to set a value using javascript. And this javascript is in a js file not in the web page.

And i include the js to this web page


When i used below code, it is not working.

document.getElementById("<%= Order_ID.ClientID %>").value = "abc";

如何为隐藏字段设置值，请帮帮我.


谢谢

推荐答案

尝试一下.

javascript:

Try this.

javascript:

function SetHdnField() {
            var x = document.getElementById('<%= hdnSomeField.ClientID %>');
            x.value = 'hi';
            return false;
        }

aspx:

aspx:

<asp:HiddenField runat="server" ID="hdnSomeField" />
   <br />
   <asp:Button runat="server" ID="btnSetValue" Text="Set Value" OnClientClick="return SetHdnField();" />

This works fine for me.
