Defer parsing of Javascript

[pilotguy]

Can anyone make some suggestions on the best way to achieve this?  I've been looking at my GTMetrix report and I have 3 items to improve, one being "Defer parsing of Javascript."  I've done a bit of searching and applied some code in the global template but it doesn't appear to have made a difference.

Hi,

I assume that you have already selected the option to have Javascript include location just before the /body tag in templates/edit/custom options? That should go a long way to helping out here.

I do and no, it hasn't changed a thing according to GTmetrix.

I just confirmed the GTmetrix a moment ago, doing another test since the last one (8 hrs prior) - The score remains 18%

You use some JS from external servers - it tells you test gtmetrix.

Try this:

Download these JS and Upload them on your server.
Edit your code template and load these JS from your server.

This will solve your problem Defer parsing.

Ok I'll let my server admin know about this!

What templates actually would I be editing?  The block itself for example for the top 3 big offenders up there are YOUTUBE video embeds using iframes in a block.

I would probably put those in 'includeJS' under global/global in templates.

Have you thought of using a service like Cloudflare? This could have a dramatic effect on your score.

You have too many errors in the template. Before optimization speed you need to fix these errors. see below

In addition to these errors on the following number of rows from your source:

1073, 1109, 1143, 1181, 1215, 1249 and 1283

you have redundant closing tag "</a>"

Go the the admin area, click on 'Customization' tab at the left-hand side and then 'Themes'.

Click on the edit button of the theme you want to change, select the 'Custom' tab and change the ' Javascript include location' option to use ' Just before </body> tag' and save.

Your JavaScript should be at the bottom of the page now.
