javascript - Check DOM element in Google Chrome Extension -



javascript - Check DOM element in Google Chrome Extension -

i trying create simple google chrome extension - finding specific element on page , display alert.

my problem specific page loads relatively slow (having ajax behind).

how can create check when page loaded?

i tried "run_at" : "document_idle" in manifest file, no success. shows me message, before whole page loads.

i thinking check every sec (or something) whole dom elements, feasible solution? think slow downwards page...

thanks.

if element not exist on page when click "view source", 1 way of catching listening domsubtreemodified event, fires each time dom modified:

document.addeventlistener("domsubtreemodified", function(event){ if(document.getelementbyid("my_element")) { //element added } });

javascript dom google-chrome google-chrome-extension
