问题描述

我们有一个搜索控件，该控件正在其他控件中使用.我在搜索控件中有复选框.我想在使用Search Controll的Controll中访问此复选框.

我在Controll中获取Search Controll的ClientId，在其中我将Search Controll用作

We have a search controll that is being used in further controlls. I have checkbox in Search Controll. I want to access this checkbox in Controll where I am using Search Controll.

I get ClientId of search Controll in controll where I am using Search Controll as

var SearchVoucherClientId = '<%= this.ucVoucherSearch.ClientID %>';

SearchVoucherClientId是存在CheckBox的Controll的搜索ID.
现在，我将CheckBox的控件ID设为

SearchVoucherClientId is the search Id of Controll in which CheckBox is Existed.
Now I aceess the Controll Id of CheckBox as

var prefix = "_ctl";
var chkCancelled = "chkCancelled"
var chkCancelledId = SearchVoucherClientId + prefix + "_" + chkCancelled;

但是chkCancelledId变量为Null.请帮助我获取正确的CheckBox ID.

谢谢

推荐答案

ASP.NET会在渲染时通过在父控件的前缀I之前修饰ID，如果使用了多个嵌套层，那么您不能只将_ctrl添加到ID中.

使用JQuery，您可以找到元素

ASP.NET will mangle the id when rendering by prefixing the parent control''s I''d, for multiple nested layers if used, so you can''t just add _ctrl to the id.

Using JQuery you could find the element

("[id

=''myControl'']")

=''myControl'']")

这将查找所有ID以我的控件结尾的元素，而不管前缀是什么

This will find any element(s) whose id ends with my control regardless of the prefix
