Determine if checkbox is checked or not in asp.net and javascript
I have a CheckBox control in an asp: Panel as shown below:
<asp:Panel ID="chk" runat="server" Visible="false" CssClass="checkbox checkbox-primary checkbox-single">
<asp:CheckBox runat="server" ID="valCheck" />
</asp:Panel>
I need to check if this CheckBox is checked or not, then I would send 0 or 1 to the function that will do a few more things and when it returns based on the value, if it is greater than 0 it will display the checked checkbox. I need to use this value because I also have some other types of inputs that I set their value based on the value returned from another call.
var checking = false;
function saveCheckBoxData(obj, id, inputType) {
if (checking) return;
checking = true;
var date = $("#MainContent_date").val();
var column = $(obj).attr("column");
var dataFieldId = $(obj).attr("dataFieldId ");
var shift = $(obj).attr("shift");
var val = 0;
//if ($("#valCheck").is(':checked')) {
// val = 1;
//}
//if ($('#valCheck').prop('checked')) {
// val = 1;
//}
//if ($('#valCheck').attr("checked")) {
// val = 1;
//}
SaveInput(dataFieldId , shift, inputType, date, column, id, val);
}
When I call the SaveInput function, I need to either go through 0 (if the checkbox is not checked) or 1 (if it is checked). The lines I commented out didn't work!
Any feedback would be greatly appreciated!

Id is not exactly valCheck
when used runat="server"
changes element id (check element to see new id) then you need to use jquery selector like:
$("select[id*='valCheck']")
or
$("select[id$='valCheck']")
or you can just add attr ClientIdMode="Static"
to your asp element.
<asp:CheckBox runat="server" ID="valCheck" ClientIdMode="Static" />
If you want to understand why this is happening, take a look at article .
