Try this regex: /^[@!#\$\^%&*()+=\-\\';\./\{\}\|\: \? ]+$/ Also you can use test . if ( pattern . test ( qry ) ) { // valid } For e.g.: function validate() { var sValue = document.getElementById(Validate).value; var pattern = /^[@!#\$\^%&*()+=\-\\';\./\{\}\|\: \? ]+$/; if (pattern.test(sValue)) { //Return True return true; } alert(Special Characters only !); return false; }
