问题 I have a Chrome packaged app that has taken me a while to get my head around but I finally have it working. However I have now come across another problem. Is it possible to save a variable from my app into a text file that's placed in my app/file directory? I have looked over the chrome.fileSystem api but I don't really understand it.

I have done my research, so far this seems to be NOT possible in Google Chrome Packaged App. Please let me

问题 Using the following code: var xhr = new XMLHttpRequest(); xhr.open('GET', url, false); Yields the following error: Uncaught InvalidAccessError: Failed to execute 'open' on 'XMLHttpRequest': Synchronous requests are disabled for this page.

问题 I have a Chrome extension that opens a KML/KMZ file in Google Maps. The extension is triggered when the user right-clicks a link to the KML document. But the context menu does not appear.
