#Firebug for chrome vs firebug lite for chrome code
Type the text that you think might help you identify the code adding the element If there's any text in the element that seems specific to it (content, id, class, some attribute, whatever), once the page is loaded you can use Chrome's powerful search feature to try to find that text:Ĭlick Ctrl+Shift+F, which is "find in files" - it looks in all of the files associated with the page, not just the "current" file Unfortuantely, it won't fire that breakpoint if the element is added during the main loading of the page (e.g., during the parsing of the HTML, by script that runs immediately rather than waiting). Now, Chrome will trigger a breakpoint when the parent element's subtree is modified, and so you can see what JavaScript code is adding the element. Right-click the parent element and click Break on. Navigate to the parent element that the target element will eventually be added to You can use Dev Tools to trigger a breakpoint when its parent element is modified: If you know which element it is, two options for you: That's not how the question originally read. js file created it and specifically what line in that. I know which element it is.what I don't know is which. Otherwise, requireJS throws an error saying that the module has not yet been loaded. Say we have module /app/scripts/methodsModule.js that returns a few methods: define( But the good news is cd() is coming to Chrome I know it's not as good as Firebugs cd(). If you want to define some variables(the hardest one): var script = document.createElement('scrept') If you want to fire a function do this: () Then you will be good to access any function and variable out there.įor example I have a variable in my iframe that is not accessible via console normally.īut still I can access to the variable via contentWindow like this: Just use contentWindow keyword in your command prompt to access the iframe window Object. Personally I don't go to Firefox just because the cd() is available in it because I can do whatever I can do with cd in chrome dev tools too.
It's making wotking with iframes much easier. Yes, you are right Firebug have this awesome command.
