问题 I have a web application that I want to run in kiosk mode on a chromebox. So far I've pretty much got it all working, but I can't seem to get rid of the annoying big white border around the screen. A screenshot of the top left corner of the screen (fullscreen). I have added a black border to outline the image. My web application starts at the blue, the white border is added by Google Chrome. My app's manifest.json : { "manifest_version": 2, "name": "snipped", "description": "snipped",

问题 I have been trying to make a Kiosk Mode App from my Chrome book. But when I go into the "Manage Kiosk Applications" and enter in the Chrome Store URL for my app, I get a "Invalid Application" error, but if i just install the app from the store, it installs just fine (though it doesn't appear Extension page, but does in the applications menu). So I assume I have done something incorrectly with App manifest. here is my manifest (just changed the names and urls as it's private application) {

问题 I'm writing app for chromebook that has to communicate with specific USB device. The device is present in the list of found devices, that comes from callback: var VENDOR_ID = 5824, PRODUCT_ID = 1159; document.getElementById("request-permission").addEventListener('click', function() { chrome.permissions.request({ permissions: [{ 'usbDevices': [{ 'vendorId': VENDOR_ID, "productId": PRODUCT_ID }] }] }, function(result) { if (result) { console.log('App was granted the "usbDevices" permission.');

问题 In this documentation there's the location for Windows, Mac OS and Linux. I assumed Chrome OS would work the same as "standard" linux, but i couldnt get my app working ... com.my_app.host.json (located in /etc/opt/chrome/native-messaging-hosts/) { "name": "com.my_app.host", "description": "My Host", "path": "/home/user/bfd93db2180e0d7645b1f4cce2d2c7ed9e0d835c/Downloads/host.sh", "type": "stdio", "allowed_origins": [ "chrome-extension://APP_ID/" ] } main.js var port = null; var getKeys =

问题 What I want to do: I want to create a Chrome extension for test purposes. And that extension should be able to access the directories and files on the local hard drive . How I did It: I requested permissions for file:///* in my manifest.json file. Then I made sure that the checkbox Allow access to file URLs was checked. Then I made a XHR for a file: var xhr = new XMLHttpRequest(); xhr.open("GET", 'file://c:/dir/file.name', true); xhr.onload = function(e) { console.log('response: ', xhr

问题 I've created a chrome app that opens in kiosk mode, inside my chrome app i have a webview which is similar to an iframe except it works for chrome apps. On the website inside the webview there is a link that tries to open in a new tab, and fails.. At the moment it just does nothing when the button is clicked. Is there a way to make all links inside the webview not open in new tabs? Or is there any other work around that you can think of? I firebugged the link and this is what it says (i was

问题 Chrome supports binary extensions on all platforms. But I cannot decide whether Chrome OS supports them too... 回答1: Nope, they are disabled on purpose. See this, this, this. 回答2: They don't support NPAPI, but they do support the new native client architecture NaCL. For more information regarding the difference: http://dev.chromium.org/nativeclient/getting-started/getting-started-background-and-basics If your binary extension uses PPAPI rather than NPAPI, it will definitely work on Chrome OS.
