app.factory('mainClass',function($http,mainFac){
var mainClass=function(){
this.uid;
this.sid;
this.getUid();
}
mainClass.prototype.getUid=function(){
var promise = mainFac.query('OPT','PARM1','PARM2');
promise.then(function(data){
console.info("mainClass is :",data);
this.sid=data.sid;
console.info("this.sid :",this.sid);
});
};
return mainClass;
});
app.controller('perCenterCtrl', function($scope, $http, $state, ngDialog,
qfact, myfactory,mainFac,mainClass) {
var mainObj=new mainClass();
console.info("mainObj is :",mainObj);
$scope.sid=mainObj.sid;
});
代码目的:
controller顺序执行,遇到名为mainClass的factory初始化,mainClass异步初始化,从后台拿到数据并更新自己的this.sid,此时在controller中也更新$scope.sid;
遇到困难:
我的理解是:$scope.sid=mainObj.sid;已经绑定了,在mainClass执行过程,异步地从后台拿到数据并更新自己的this.sid后,$scope.sid应相应更新自己的值,可是并没有更新;

没太看懂,你这么写写试试。建议你看看这个:http://each.sinaapp.com/angular/tutorial/ng-factory.html
