I took some checkboxes in the following way.I should get a message if atleast 1 checkbox is not checked and the values should not be entered into the database.This is the validation i needed.I have written the javascript code as below:but instead of 'controls[]' there should be a groupname which combines all the checkboxes.Iam not understanding what name to give here.Can any one please help me out
<script type="text/javascript" language="javascript">
function validate() { var chks = document.getElementsByName('controls[]'); var hasChecked = false; for (var i = 0; i < chks.length; i++) { if (chks[i].checked) { hasChecked = true; break; } } if (hasChecked == false) { alert("Please select at least one."); return false; } return true; } </script>
