javascript - Chrome 扩展在加载同步数据后运行 Angular

Question

从 chrome.storage 获取数据后如何运行 angularjs 引擎？

我在 app.js 中有这段代码:

'use strict';

var host = '';
var port = '';
chrome.storage.sync.get({
    host: '',
    port: '',
}, function(items) {
    host = items.host;
    port = items.port;
});
// need to run this line after data is retrived from chrome.storage
var app = angular.module('TouchApp', ['TouchApp.services', 'TouchApp.controllers', 'TouchApp.directives']); 

chrome获取到数据后，然后运行angularjs引擎。

有什么解决办法吗？

回调的目的是在异步函数完成后运行。所以你需要在那里放置代码。

var app;

chrome.storage.sync.get({
    host: '',
    port: '',
}, function(items) {
    host = items.host;
    port = items.port;
    app = angular.module('TouchApp', ['TouchApp.services', 'TouchApp.controllers', 'TouchApp.directives']);
});
