jQuery的运行code AngularJS完成渲染之后的HTML [英] Run jQuery code after AngularJS completes rendering HTML

问题描述

在控制器我得到使用$ http或$资源服务的一些JSON数据。然后我在$范围写这个数据和AngularJS更新HTML页面的结构。我的问题是，我需要知道什么是列表的新尺寸（宽和高）（我的意思是，HTML DOM元素）充满角 NG-重复指示。因此，我有角完成更新DOM结构后运行JavaScript code正确。是什么做的正确方法？我已经搜索互联网在过去四年小时，但我找不到任何解决我的问题。

In controller I get some JSON data using $http or $resource services. Then I write this data in $scope and AngularJS updates HTML structure of the page. My problem is that I need to know what is the new size (width and height) of the list (I mean, HTML DOM element) that is filled with Angular ng-repeat directive. Consequently, I have to run javascript code right after Angular finishes updating DOM structure. What is the proper way to do it? I have searched internet over the last four hours but I couldn't find any solution to my problem.

这是我如何收到JSON数据：

This is how I receive JSON data:

var tradesInfo = TradesInfo.get({}, function(data){
    console.log(data);
    $scope.source.profile = data.profile;
            $scope.trades = $scope.source.profile.trades;
        $scope.activetrade = $scope.trades[0];
        $scope.ready = true;


    init();  //I need to call this function after update is complete

});

和这是会发生什么的init（）功能：

function init(){
    alert($('#wrapper').width());
    alert($('#wrapper').height());
}

我知道一定有什么容易解决这个问题，但我不能找到它了。
先谢谢了。

I know that there must be something easy to solve this problem but I can't just find it now. Thanks in advance.

推荐答案

其实在这种情况下角的方式是不容易的方式，但唯一正确的方式：）

Actually in this case the angular way is not the easy way but the only right way :)

您必须写一个指令，并连接到你想知道的高度的元素。而从控制器您$广播一个事件时，directive'll捕捉事件，那里你可以做的DOM操作。从来没有在控制器中。

You have to write a directive and attach to the element you want to know the height of. And from the controller you $broadcast an event, the directive'll catch the event and there you can do the DOM manipulation. NEVER in the controller.

var tradesInfo = TradesInfo.get({}, function(data){
    console.log(data);
    $scope.source.profile = data.profile;
    ...

    $scope.$broadcast('dataloaded');
});


directive('heightStuff', ['$timeout', function ($timeout) {
    return {
        link: function ($scope, element, attrs) {
            $scope.$on('dataloaded', function () {
                $timeout(function () { // You might need this timeout to be sure its run after DOM render.
                    element.width()
                    element.height()
                }, 0, false);
            })
        }
    };
}]);
