javascript - Disable Required Field Validator based on RadioButton Check -

the code should enable false when radiobutton value ==2. every time click submit button prompts me requiredfieldvalidator lastname textbox.

thank you!

$('#<%= rblindorg.clientid %>').change(function() { if ($('#<%= rblindorg.clientid %> input:checked').val() == "2") { $('#<%= tblast_name.clientid%>').val(""); $('#<%= tblast_name.clientid %>').attr("style", "display: none;"); $('#lbllast_name').attr("style", "display: none;"); document.getelementbyid("<%=rfv_tblast_name.clientid%>").enabled = false; } else { $('#<%= tblast_name.clientid %>').attr("style", "display:inline;"); $('#lbllast_name').attr("style", "display: block;"); document.getelementbyid("<%=rfv_tblast_name.clientid%>").enabled = true; } });

try not disable tblast_name remove required-attribute (if exists)

$('#lbllast_name').attr("style", "display: none;"); $('#lbllast_name').removeattr('required');

in else block should add together required-attribyte @ first line again.
