[jQuery] [Howto] Validate a form in two part

[jQuery] [Howto] Validate a form in two part


e.g:
<form>
<fieldset id='1'>
<input class='text' />
.......<button>CHECK 1</button>
</fieldset>
<fieldset id='2'>
<input class='text' />
.......<button>CHECK 2</button>
</fieldset>
</form>
if I use "ignore: '1' ", It seems not working.
I just want to check a form in 2 part, at different click.
