Hello, anyone has idea how to do dynamic form validation?

e.g. using http://bassistance.de/jquery-plugins/jquery-plugin-validation/

<input name="t1" type="text" />
<input name="t2" type="text" />


I only want to check for required field for t2 ONLY if t1 is equal to
some value

e.g.

If t1 = "test", then t2 cannot be null, else never mind abt t2

Try this:

$("...").validate({
    rules: {
        t2: {             required: function(element) {
                return element.value == "test"
            }
        }
    }
});

By passing a function as the argument to the required-rule you can specify whatever dependency you can think of. More examples can be found here: http://jquery.bassistance.de/api-browser/plugins.html#jQueryvalidatormethodsrequiredStringElementBooleanStringFunction

How I can see the correct code would be:

$("#theform").validate({
   rules:{
      t2: {
         required: function(element){
            return $(t1).value == "test";
         }
      }
   }
});
