问题 I'm new in Chrome Web App programming. I want a simple WebApp which is separated to my Chrome/Chromium (means no tab). It shall show a external website in the body. So here is my configuration: manifest.json { "name": "Hello World!", "description": "My first Chrome App.", "version": "0.1", "manifest_version": 2, "permissions": [ "webview" ], "icons": { "128": "icon_128.png" }, "app": { "background": { "scripts": ["background.js"] } } } background.js chrome.app.runtime.onLaunched.addListener

问题 I'm trying to create a chrome extension which scans a local directory for new files ... However, if I add the file://* permission to the manifest I can access the internal file browser of chrome with xmlhttp.open("GET","file://C:/Users/username/Desktop/",false); xmlhttp.send(); console.log(xmlhttp.response); From the response I could extract the file URLs and use them in my extension. My question is now: Are there other approaches? The above way seems more like a workaround and easily breaks

问题 Is there a way in javascript or in chrome extension API to instantly (without saving the timestamp during the loading time) get the timestamp of when the DOM of the page was loaded in Chrome? 回答1: You can use the performance.timing object (implemented by all modern browsers, except Safari) to get all kinds of different timestamps. You need to see for yourself what timestamp would be most appropriate for you. "when the page was loaded" is quite a vague description. Otherwise, be more specific.

Surprisingly I was not able to find a way to do this, even googling for
