I’m working on a web project that uses jQuery. I want to get rid of jQuery UI because it’s too big and write my own easing functions instead. But after removing jQuery UI, I’m getting a non-stop error in Chrome’s DevTools.
The error keeps popping up and I can’t seem to stop it. It’s like the page is stuck in an endless loop. I know how to fix the bug, but I’m wondering if there’s a way to pause the page when this happens.
Is there some kind of command or setting in Chrome’s DevTools that can help me stop the execution when it hits this kind of infinite loop? It would be really helpful for debugging.
hey john, been there! chrome’s got ur back. hit F8 or click the pause button (looks like two vertical lines) in devtools when the loop starts. it’ll freeze everything so u can check what’s up. lifesaver for catching those pesky infinite loops. good luck with ur jquery tweaks!
I’ve encountered similar issues when optimizing jQuery-heavy projects. One effective method I’ve found is using the ‘Pause on exceptions’ feature in Chrome DevTools. You can enable this by clicking the pause icon with a pause symbol inside a hexagon. It’s located in the Sources panel.
When activated, it automatically pauses execution when an error occurs, which is invaluable for tracking down elusive bugs like infinite loops. Additionally, strategically placing debugger statements in your code can help. Just insert ‘debugger;’ at key points, and the execution will pause there when DevTools is open.
For performance analysis, the Performance tab in DevTools is a goldmine. It allows you to record and analyze your script’s execution, helping identify bottlenecks or runaway processes. These tools combined have saved me countless hours of debugging frustration.
Have you considered using the Performance tab in Chrome DevTools? It’s a powerful tool for catching and analyzing infinite loops. Start a recording, let it run for a few seconds, then stop it. You’ll see a timeline of JavaScript execution. Look for long, uninterrupted blocks of script running - that’s often where infinite loops hide.
Another trick is to use console.log statements strategically. Place them at key points in your code, especially where you suspect the loop might be. If you see the same log repeating endlessly, you’ve found your culprit.
These methods, combined with the pause button others mentioned, should give you a good arsenal for tackling those tricky infinite loops. Best of luck optimizing your jQuery code!
