Hey Yonggang, You might find nsIWebProgressListener useful: https://developer.mozilla.org/en-US/docs/Mozilla/Tech/XPCOM/Reference/Interface/nsIWebProgressListener
Specifically the onLocationChange method. This is fired once we've determined that we're going to load a new URI for a DOM Window. From the passed in nsIWebProgress[1], you should be able to get at the nsIDOMWindow, and from there, I *think* you can get to the nsIDocShell by QI'ing the nsIWebProgress to an nsIInterfaceRequestor and then GetInterface'ing nsIDocShell. I haven't tried this, but I'm reasonably certain it will work. -Mike [1]: https://dxr.mozilla.org/mozilla-central/rev/9ed17db42e3e46f1c712e4dffd62d54e915e0fac/uriloader/base/nsIWebProgress.idl#134 On 13/09/2015 8:17 AM, 罗勇刚(Yonggang Luo) wrote: > So that I know what's the docshell is and the URL is. > _______________________________________________ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
