这是用jquery实现的批量删除，脚本获取选定值，然后放到服务器控件隐藏域中，后台代码获取id，批量删除
//获取input所在的对象
var ob = document.getElementById("Repeater1");//获取div中所用的IUPUT控件集合
var col = div1.getElementsByTagName("INPUT");
var str="";
var count=0;
//循环遍历，判断INPUT是否选中
for(var i=0 ;i<col.length;i++)
{
if(col[i].checked==true)
{
count++;
}
}
if(count>0)
{
}
else
{}
