jQuery primer
- Oldie but goody
- Makes you look smart without being a JavaScript expert
- Relatively straightforward syntax
Examples
Change a button label:
<button id="pay" class="usa-button">Complete payment</button>
$('button#pay').html('Processing…')
Change a button label after clicking it:
<button id="pay" class="usa-button">Complete payment</button>
$('button#pay2').on('click', function(){
$('button#pay2').html('Processing…');
$('button#pay2').attr('disabled', true);
});
