禁用Java中的Asp.Net文本框 [英] Disabling Asp.Net Textbox in Javascript

问题描述

我想在检查Asp.Net复选框时禁用Asp.net文本框.

它给了我以下错误.
"Microsoft JScript运行时错误:"df.cbAddress"为空或不是对象"

这是我的Javascript函数

I want to disable the Asp.net textbox when I check the Asp.Net Checkbox.

It gives me the following error.
"Microsoft JScript runtime error: ''df.cbAddress'' is null or not an object"

Here is my Javascript function

function GetBillingAddress()
{

    df = document.form1;

        if (df.cbAddress.checked) {
            document.getElementById("txtBillStreet").disabled = true;
            document.getElementById("txtBillCity").disabled = true;
            document.getElementById("txtBillState").disabled = true;
            document.getElementById("txtBillZip").disabled = true;
        }
        else {
            document.getElementById("txtBillStreet").disabled = false;
            document.getElementById("txtBillCity").disabled = false;
            document.getElementById("txtBillState").disabled = false;
            document.getElementById("txtBillZip").disabled = false;
            }

}

在页面加载中，我有以下内容

In Page Load I have the following

protected void Page_Load(object sender, EventArgs e)
    {
        cbAddress.Attributes.Add("onClick", "GetBillingAddress();");
    }

任何帮助将不胜感激.

感谢''s

Any help will be appreciated.

推荐答案

如果您在asp.net控件中执行"runat = server"，则不能仅通过其id引用它们

您必须执行以下操作:

document.getElementById(''<％= txtBillStreet.ClientID％>''))

意见建议:
将所有地址控件包装在一个asp.net面板控件中，然后启用/禁用该功能.

if you doing "runat = server" in your asp.net controls you can''t just refer them by their id''s

you have to do something like this:

document.getElementById(''<%= txtBillStreet.ClientID %>'')

suggestion:
wrap your all address controls in one asp.net panel control and enable/disable that.

如果帖子已解决，请提供已解决符号.

If the post is resolved give the Resolved symbol.

使用此功能

<code>function GetBillingAddress()
{
 
    df = document.getElementById(''<%= cbAddress.ClientID %>'');
 
    document.getElementById(''<%= txtBillStreet%>'').disabled = df.checked;
    document.getElementById(''<%= txtBillCity%>'').disabled = df.checked;
    document.getElementById(''<%= txtBillState%>'').disabled = df.checked;
    document.getElementById(''<%= txtBillZip%>'').disabled = df.checked;

}</code>
