Вот пример, который вы можете проверить: http://jsfiddle.net/W8EsU/
HTML
<form id='theForm'>
<input id='test_field' name='test_field' value='jQuery' />
<br>
<input id='test_field2' name='test_field2' value='prototypejs' />
</form>
JQuery
// Add a validation method to the validator plugin
// that can be applied as a rule to whatever fields
// you want. That way you get your custom validation
// integrated into the functionality of the plugin
$.validator.addMethod(
"mustIncludejQuery",
function(value, element) {
return value.toLowerCase().indexOf('jquery') > -1;
},
"You must type jQuery to be valid."
);
// Apply the custom validation to the fields
$('#theForm').validate({
rules: {
test_field:'mustIncludejQuery',
test_field2:'mustIncludejQuery'
}
});
// Demonstrates that they will be executed
// like any other validation rule.
$('#theForm').valid();
