javascript正则验证特殊字符并过滤

<script type="text/javascript">
$("#search").click(function(){
    var name = $("#title").val();
    var regEx = new RegExp(/^(([^^.<>%&',;=?$"':#@!~][{}/`|])*)$/);
    var result = name.match(regEx);
   
    if (result == null) {
    $("#tip").empty();
$("#tip").append("<font color='red'>输入非法，包含特殊字符</font>");
return false;
    }else{
    $("#tip").empty();
    document.forms[0].submit();
    }
});
</script>
