如何从用户控件中找到控件ID [英] How to find control id from user control

问题描述

我有一个Web用户控件，其中包含"AssociatedLableId"属性和标签.

I have a web user control which contains ''AssociatedLableId'' property and a label.

<uc1:UC id="uc1" run="Ser" AssociatedLableId="lblLable" />

并在aspx页面和已注册的用户控件中添加了一个Label和一个按钮.
现在，当我单击按钮时，aspx页面的标签控件文本将分配给使用JS的Web用户控件的标签控件.
我尝试关注但不正确.

and added a Label and a button in aspx page and registered User Control .
Now when I click the button then the text of label control of aspx page assigned to label control of web user control using JS.
I tried following but not right.

<asp:button id ="btn" run="Ser" text="Click" onClientClick="return assignValue();" />
function assignValue()
{
     document.getElementById('UserControlsAssocitedControlId').value = document.getElementById('aspxPageLableId').value;
}

AssociatedLableId属性用于获取aspx页的Label控件的ID.
我可以找到UserControlsAssocitedControlId的ID，但是如何找到我在JS的AssociatedLableId 属性中分配的aspxPageLableId.

AssociatedLableId property is used to get the Id of aspx page''s Label control.
I can find the Id of UserControlsAssocitedControlId but how can I find the aspxPageLableId which I assigned in the AssociatedLableId property in JS.
