如何使用JAVASCRIPT在gridview的模板列中选择至少一个复选框 [英] How to SELECT atmost one checkbox in a template column of gridview USING JAVASCRIPT

问题描述

朋友们，

我正在使用VS 2005，.net框架2，asp.net，c#.net
我有一个gridview，其中在模板列中包含一个复选框.
我想检查是否至少要选中一个复选框吗?
这意味着，当单击另一行中的复选框时，应该取消选中先前选中的检查
是否可以在Javascipt中进行?

推荐答案

<pre lang="text">

You mean only one check box allowed to checked if so you can do it using JQuery in such a manner


#1:- In template Column write the checkbox ID like 
         <asp:checkbox id="chk_"+ID onclick="SelectOne(ID);">

ID will be  PK fields which you are getting from database 

 funtion SelectOne(Id){
  //find all the checkbox into the grid unchecked

('input [id * ="chk _"]').removeAttr("checked"); ////然后检查您单击的内容

('input[id*="chk_"]').removeAttr("checked"); // then make checked what you have clicked

(#chk_" + ID).attr("checked"，"checked"); } 如果有任何问题写信给我，请尝试一下 谢谢

("#chk_" + Id ).attr("checked", "checked"); } TRY THIS WILL WORK IF ANY ISSUE WRITE ME THANKS
