如何知道浏览器的内置对象已准备就绪？

Question

The background: The wechat JS API is on the foundation of wechat build-in browser object WeixinJSBridge. The WeixinJSBridge is not ready immediately when open the WebView,client side need initialize this object， when this object is ready，client side will fire "WeixinJSBridgeReady", so before invoke WeixinJSBridge API， we need check WeixinJSBridge is ready or not:

if (typeof WeixinJSBridge == "object" && typeof WeixinJSBridge.invoke == "function") {
    WeixinJSBridge.invoke'API()....
} else {
    if (document.addEventListener) {
        document.addEventListener("WeixinJSBridgeReady", callback, false);
    } else if (document.attachEvent) {
        document.attachEvent("WeixinJSBridgeReady", callback);
        document.attachEvent("onWeixinJSBridgeReady", callback);
    }
}

here is the question: how can I do this check in context of angular, i want put this stuff in one controllers.

Use .run: http://docs.angularjs.org/api/angular.Module

var app = angular.module('myApp',[]);
app.run(/*standard function and scope*/);
