javascript - Jquery input value not showing up correctly -

javascript - Jquery input value not showing up correctly -

i have simple input value.

the code looks this:

var $a = $('.custom-amount').val(); $('.custom-amount').on('change', function() { alert($a) })

and input:

<div class='custom-amount'> <input placeholder='custom amount' type='text-area'>

for reason, alerts empty. see whats going wrong?

change selector $('.custom-amount input'), , value after alter event fired, e.g.

$('.custom-amount input').on('change', function() { var = $(this).val(); alert(a); });

right now, trying value of div, won't work. need value of input.

edit: also, looks trying display textarea. seek replacing this...

<input placeholder='custom amount' type='text-area'>

with this...

<textarea placeholder='custom amount'></textarea>

this may help:
