How to check if script tags are entered in a field

jQuery.validator.addMethod("disableScript", function(text, element) {
return (text.match(/\<\bscript\b/i) || text.match(/\<\/\bscript\b/i))?false:true;
}, "Script tags are not allowed");

And how to use it?? It's very simple.

Just add this method to the list of rules to validate the particular input field.


rules: {
first_name: {required: true, disableScript: true},
comment: {disableScript: true}

The JQuery validator plugin js file should be included in the page for this to work.
