Trying to detect Top Url in chrome.webNavigation.onBeforeNavigate

[Eli Tchernitski]

Hi,

I created extension that uses webNavigation.onBeforeNavigate

currently I just use alert for testing.

The problem is that it fires many times for each page and I need only  top url.

How to detect it ?

(for ex. in C++ API for IExplore there is get_TopLevelContainer for IWebBrowser2)

chrome.webNavigation.onBeforeNavigate.addListener(

  function (object) {

      if ( object.url.indexOf("http") > -1)

      {

          //if (  topUrl ) /  

 alert('object.url - '+object.url);

     }

  });

May be anybody can help ?

The object which has the URL property, also has a frame ID (see documentation at http://developer.chrome.com/extensions/webNavigation.html#event-onBeforeNavigate):

frameId ( integer )

0 indicates the navigation happens in the tab content window; a positive value indicates navigation in a subframe. Frame IDs are unique for a given tab and process.

Hi,

In which file you wrote the code, backgrund.js or navigation_collector.js,

A single url sometimes call hidden background navigation for website navigations, check for only google.co.in, and tell me how much time it shows alert.

I may help you because I just done a this like project with a lot of r & d and problems.

Thanks

Thats true, if you check for the "framId" == 0, you'll be insuring that this is infact the top URL. However, the problem with onBeforeNavigate is that its still experimental. It fires not only if you navigate to a different URL, but if you try typing in your omni box a URL, as soon as the autocomplete functionality kicks in, it triggers a onBeforeNavigate event as well. Unfortunate i have no solution for this issue.
