问题 Dart doesn't show the alert dialog when I use a webview and show this error: : An alert dialog was blocked. (extensions::webViewEvents:225) : A confirm dialog was blocked. (extensions::webViewEvents:225) Does anyone know how to bypass the problem or how to catch the error? Thanks. Sorry for my bad English. Edit The code used: Element webview= querySelector("#webview"); Map<String,String> map=new Map(); map["src"]=urlWebView; webview.attributes.addAll(map); webview.style.visibility="visible";

问题 I'm trying to get a polyfill for the issue with input[type=file] on Android 4.4. chrome.fileSystem.chooseEntry shows the dialog but not the callback. Anyhow this look(s)/(ed) promising: https://github.com/cdibened/filechooser but using the "cca plugin add..." instead of "cordova plugin add..." fails. Other posts recommend doing everything through the cca toolchain. What is the best approach? What are other developers doing about the issue with input[type=file] on Android 4.4? Thanks, Nic 回答1:

问题 I am trying to write a Chrome app that would support printing to old printers connected to the computer via the parallel port. I found out that Chrome apps can not use any kind of NPAPI plugins so those are out of the question. The remaining option seems to be NaCl or PPAPI plugin. But does PPAPI or pepper or NaCl (I am not very familiar with any of them and am probably using them in the wrong context) support access to the parallel port? Can a PPAPI plugin be written, which supports parallel

问题 I want to modify chrome start page, change background and maybe logo. I want to include jQuery in users local storage and load it while users page loads ( search page ) I never done anything with chrome so I want some way where to start. Do I go reading with apps or extensions? 回答1: As a rule of thumb: Choose an app if you want to develop an (independent) application that can stand on its own. If you want to interact with the browser (e.g. modify a web page), build an extension. In your case,

问题 I am using chrome.identity.launchWebAuthFlow() to direct a user through OAuth2 of a non-Google API when they use my extension. Even though authentication works and I can effectively get the user's authentication token, I dislike that it opens up entirely in a new window that lacks the browser's UIs and a URL bar. Ideally, I would be able to conduct this OAuth dance within the extension's popup window. If that doesn't work, being able to at least have this OAuth event take place in a separate

问题 Since packaged apps can run on different platforms, is there any way to distinguish between Windows and Mac ? I would like to show some help vis-à-vis keyboard shortcuts and being able to detect the OS would help in for example showing Command ⌘ C or Ctrl C accordingly. 回答1: You can use window.navigator in JS. Typically that will have the information you're looking for. Probably in window.navigator.platform. 回答2: You can also use the new chrome.runtime.getPlatformInfo API (https://developer

问题 I'm building a Chrome packaged app called Git Crx and as the name suggests it needs to go network requests to and from remote git repos using HTTPS (smart protocol) BUT if you attempt to do an XHR request to a url that returns 401, the XHR will fail without using the normal browser credentials machinery whereas previously packaged apps would show the browsers normal credentials request UI. Now I think that does makes sense to me now, as Chrome Apps are supposed to be stand alone apps and not
