Javascript无法在Chrome中运行 [英] Javascript not working in Chrome

问题描述

有人可以告诉我为什么这个简单的javascript无法在Google Chrome中运行吗？

Can anybody tell me why this simple javascript not working in google chrome?

<script type="text/javascript" language="javascript">
function getRdoValue()
{
    if(document.getElementById("rdo_yes").checked)
    {
          document.getElementById("dlst_type").disabled=false;
          document.getElementById("dlst_course_wocktube").disabled=false;
    }
    if(document.getElementById("rdo_no").checked)
    {
        document.getElementById("dlst_type").disabled=true;
        document.getElementById("dlst_course_wocktube").disabled=true;
    }
}
</script>

ASP.NET表单：

ASP.NET Form:

<asp:RadioButton ID="rdo_yes" runat="server" Text="Yes" GroupName="rdo1" onChange="getRdoValue();" />
       <asp:RadioButton ID="rdo_no" runat="server" 

Checked="True" Text="No" GroupName="rdo1" onChange="getRdoValue();" />

<asp:DropDownList ID="dlst_type" runat="server" Enabled="false" AutoPostBack="True" OnSelectedIndexChanged="dlst_type_SelectedIndexChanged">
        </asp:DropDownList>

<asp:DropDownList ID="dlst_course_wocktube" runat="server" Enabled="false">
        </asp:DropDownList>

推荐答案

在编写javascript时，每个asp.net开发人员都会犯下经典错误。你需要使用asp.net控件的客户端ID。您正在使用javascript中的服务器ID。它不适用于Chrome以及任何其他浏览器。



使用此语法

You are making the classical mistake every asp.net developer makes for the first time while writing the javascript .You need to use client ID of the asp.net control. You are using the server id in the javascript. It will NOT work in Chrome as well as any other browser.

Use this syntax

var b = document.getElementById('<%=Button1.ClientID%>');
