Chrome-Extension: iterate through all tabs?

Question

How would I iterate through all tabs a user has open and then check if they have a particular HTML item with id = \'item\'?

Answer 1

I use this one

chrome.tabs.getAllInWindow(null, function(tabs) {
      $.each(tabs, function() {
        // u can use 'this.id' to work with evey tab 
      });
});
