Question

I want to replace all ’20’ inside the id=”olderpost” with ’30’

I did the following:

<div id="olderpost"><a onclick="$.ajax({ dataType: 'script', url: '/actions/olderpost/20'}); return false;" href="/actions/olderpost/20">View older actions</a></div>

$('#olderpost').html().replace('20', '30');

but nothing changed.

Answer 1

replace doesn’t mutate the string. Try this:

$('#olderpost').html($('#olderpost').html().replace(/20/g, '30'));
