GridView CheckBox实现全选

<script type="text/javascript">    function chkSelectAll(oCheck)    {        //获取Table对象        var oTable = document.getElementById("GridView1");        if(oTable)        {            //获取Table内所有input对象            var oInputs = oTable.getElementsByTagName("input");            //遍历所有Input对象            for(var i=0;i<oInputs.length;i++)            {                //判断Input的类型是否为"checkbox"                if (oInputs[i].type=="checkbox")                {                    oInputs[i].checked = oCheck.checked;                }            }        }    }</script>
