GridView 全选

GridView全选处理：

1.客户端脚本实现。

2.服务器端实现。

<script type="text/javascript">

        function ConfirmSubmit() {
            if (confirm('您确定要删除吗？')) {
                return true;
            }
            else {
                return false;
            }
        } 
        function Check(parentChk,ChildId) 
        {     
            var oElements = document.getElementsByTagName("INPUT");
            var bIsChecked = parentChk.checked;    
            for (i=0; i<oElements.length;i++)     
            {         
                if (IsCheckBox(oElements[i]) && IsMatch(oElements[i].id, ChildId))
                {
                    oElements[i].checked = bIsChecked;         
                }
            }  
          }
        function IsMatch(id, ChildId) {
            //gvList_ctl06_CheckBox1
            var sPattern = '^gvList_ct.*' + ChildId + '$'; 
            var oRegExp = new RegExp(sPattern);     
            if(oRegExp.exec(id))          
                return true;     
            else          
                return false; 
        }  
        function IsCheckBox(chk) 
        {     
            if(chk.type == 'checkbox')
