Chrome extension: How to manipulate inner Gmail DOM with jQuery? -

-

whilst no problem manipulate inner gmail content css content script, fail jquery , custom js content script.

i want use jquery manipulate inner gmail dom.

manifest.json

"content_scripts": [ {         "matches":      ["*://*.mail.google.com/*"],         "js":           ["jquery.js", "default.js"]     } ],

default.js

$(document).ready(function() {     $("div.gk").css("color", "red"); });

however, respective div.gk element not reflect css changes:

enter image description here

any ideas why not work?

the domready event fires long before target element created. when go mail.google.com you'll notice loading bar - before appears event fired.

i'm not sure if gmail has custom events more reliable, otherwise i'd suggest using

jquery(window).load(function(){   jquery("div.gk").css("color", "red"); });

if feel dissecting events in more detail suggest reading on , using chrome developer tools, focus on timeline tab.
