Jquery用户控件(Jquery user control)

 我有一个问题，没有在asp用户控件中加载jquery。 
 
 我只想在单击复选框时添加click事件。 
 
 这是我的javascript文件 
 
$(document).ready(function() {
    var arr = jQuery(":checkbox[id*='drpAccountType']");
    for (i = 0; i < arr.length; i += 1) {
        $("#" + arr[i].id).click(function() { alert(this.id) });
    }
});
if (typeof (Sys) !== 'undefined') Sys.Application.notifyScriptLoaded();
 
 用户控制预渲染事件： 
 
Protected Sub Page_PreRender(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.PreRender
        ScriptManager.RegisterClientScriptInclude(Me, Me.GetType, "CheckboxdropdownScript", ResolveUrl("~/Scripts/CheckBoxDropDown.js"))
End Sub
 
 脚本加载正常，但jQuery的任何用法都返回undefined。 然后只有在加载页面时，我才能在firebug中为commande行执行相同的代码。 jquery库加载在母版页中。 
 
 每当我在asp用户控件中使用jquery时，我总会发现问题，而且我总是不得不破解它以使其工作。 我尝试了stackoverflow中的所有条目，但我从来没有找到一个作为一般解决方案。 
 
 有没有人发现一个简单的解决方案，使用jquery与母版页，用户控制在asp.net我会很感激，如果有人可以分享这些有价值的信息。 
 
 我的经理即将从应用程序中删除jquery，因为我们总是花费大量时间来找到一个解决方法，让它与用户控件一起工作。 
 
 请帮助，我喜欢jquery，我真的想将它用于客户端脚本。 
 
 最好的祝福 

I have a problem with jquery not loaded in an asp user control.
 
I want simply to add the click event when a checkbox is clicked.
 
Here is my javascript file 
 
$(document).ready(function() {
    var arr = jQuery(":checkbox[id*='drpAccountType']");
    for (i = 0; i < arr.length; i += 1) {
        $("#" + arr[i].id).click(function() { alert(this.id) });
    }
});
if (typeof (Sys) !== 'undefined') Sys.Application.notifyScriptLoaded();
 
The user control pre render events:
 
Protected Sub Page_PreRender(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.PreRender
        ScriptManager.RegisterClientScriptInclude(Me, Me.GetType, "CheckboxdropdownScript", ResolveUrl("~/Scripts/CheckBoxDropDown.js"))
End Sub
 
the script is loaded fine but any usage of jQuery return undefined. Then only when the page is loaded I can excute the same code for the commande line in firebug. The jquery library is loaded in the master page.
 
Whenever I'm using jquery within an asp user control I always find problems, and I always have to hack around to get it to work. I try all the entries in stackoverflow but I never found a one as general solution.
 
did any one found a simple solution to use jquery with master pages, user control in asp.net I would appreciate if someone can share such valuable information.
 
My manager is about to drop jquery from the application as we always waist lot of time just to find a workaround to have it to work with user controls.
 
Please help, I like jquery and I really want to use it for client script.
 
best regards
