JQuery Not Triggering On Radio Button Change

Sorry for bothering, but I'm new to jquery and trying to figure this out. Thanks in advanced. I have a web page filled with several sets of radio buttons based on several computer

Solution 1:

You can trigger the change event using .trigger():

...
$('input:radio[name=psu]')[1].checked = true;
$('input:radio[name=hdd]')[2].checked = true;

$('input:radio').trigger('change');

Also, don't use input:radio. input:radio isn't a CSS selector and won't be supported by document.querySelector, so it will run slower than input[type="radio"].

I suggest you re-think your layout. You should't have to repeat the same block of code every time with just minor changes.
