asp.net - Get the value of a hidden column in a gridview with javascript -

i have function (below) works wonderful need hide column 'customerid' gives me value var customerid = grid.rows[i].cells[1].innertext; if hide column function no longer works works it's grabbing wrong value. can this?

the hidden field looks this...

<asp:templatefield>   <itemtemplate>     <asp:label id="lblcustomerid" runat ="server" text='<%# eval("customerid")%>'/>   </itemtemplate> </asp:templatefield> 

function:

function mapselectedclick()  {     var customerids = "";     var grid = document.getelementbyid('<%=grdcustomers.clientid %>');     var count = 0;      (var = 1; < grid.rows.length; i++)     {         var cell = grid.rows[i].cells[0];          var customerid = grid.rows[i].cells[1].innertext;         (var j = 0; j < cell.childnodes.length; j++)         {             if (cell.childnodes[j].type == "checkbox")             {                 if (cell.childnodes[j].checked)                 {                     customerids += customerid.tostring() + ',';                     count++;                 }             }         }     }      if (count == 0)     {         alert("please select @ least 1 customer map.");         return false;     }      customerids = customerids.substring(0, customerids.length-1);     window.open("mapcustomers.aspx?customerids=" + customerids); } 

i think better add value="<%# eval("customerid")%>" checkbox.

and use like:

if (cell.childnodes[j].type == "checkbox") {     if (cell.childnodes[j].checked)     {         customerids += cell.childnodes[j].value.tostring() + ',';         count++;     } } 

or use same name checkboxes:

<input type="checkbox" name="checkedcustomers" value="1" /> <input type="checkbox" name="checkedcustomers" value="3" /> 

in js:

var checkedcustomers = document.getelementsbyname("checkedcustomers"); var customerids = []; (var = 0; < checkedcustomers.lenght; i++) {     if(checkedcustomers[i].type === 'checkbox' && checkedcustomers[i].checked)         customerids.push(checkedcustomers[i].value); } var result = customerids.join(',');
