试试这个

try this

function Fn_JsOrders_GetCheckBoxList() {
           var jsVar_Orders_OrderId = "";
           var flag = false;
           // alert(document.aspnetForm.OrderId.length);
           var ctrls = document.getElementsByTagName("input");
           for (var i = 1; i < ctrls.length; i++) {
               if (ctrls[i].checked == true) {
                   //  alert(jsVar_Orders_OrderId);
                   jsVar_Orders_OrderId = jsVar_Orders_OrderId + ctrls[i].value + ",";
               }
           }
           if (jsVar_Orders_OrderId.length == 0) {
               alert("Please Select Atleast One item");
               flag = false;
           }
           else {
               document.getElementById("<%=hid_Hospital_HospitalId.ClientID %>").value = jsVar_Orders_OrderId;
               var answer1 = confirm("Are You Sure You Want to Delete ?");
               if (answer1) {
                   flag = true;
                   document.aspnetForm.submit();
               }
               else {
                   flag = false;
               }
           }
           return flag;
       }

尝试一下

function getID(ctrl)
{
        var dt = document.getElementById(''<%=GridView1.ClientID %>'')
        var items = dt.getElementsByTagName(''input'')
        
        document.getElementById(''<%=t.ClientID %>'').value = '''';
    for(i=0; i<items.length;>    {
            if(items[i].type == ''checkbox'' && items[i].checked)
                document.getElementById(''<%=t.ClientID %>'').value += '','' + items[i].id
    }
}

然后这样称呼

and call this like that

<asp:checkbox id="chk1" runat="server" onclick="getID(this)" xmlns:asp="#unknown" />
