如何在angularjs中创建一个函数同步执行

Question

我如何制作storyboard.getAdressTimeLine同步，我想要storyboard.drawTimeLine执行，直到storyboard.getAdressTimeLine完成

for (var i = 0; i < response.data.length; i++) {
var obj=response.data[i];
var date = obj.fixtime.substring(0, 11);
storyboard.getAdressTimeLine(obj.latitude,obj.longitude);
storyboard.drawTimeLine(date + "00:00:00.000+0000", obj.fixtime, "red",0,storyboard.lastAdressTime);
items.push(item);

}

在这里使用promises这个angularjs文档将帮助你https://docs.angularjs.org/api/ng/service/ $ q

如果您使用承诺，您的功能将如下所示

storyboard.getAdressTimeLine(obj.latitude,obj.longitude).then(function(){
 storyboard.drawTimeLine(date + "00:00:00.000+0000", obj.fixtime, "red",0,storyboard.lastAdressTime);
})
