问题描述

我想实现在angularJS应用packery。

当我定义项手动一个一个(见注释HTML code),Packery工作正常。
当我尝试做同样的事情与NG-重复循环,packery不起作用。

如何才能与NG-重复packery工作在angularJS模板?

模板:

 < D​​IV CLASS =项容器工作空间>  < D​​IV CLASS =模块施胶机>< / DIV>
  < D​​IV CLASS =阴沟施胶机>< / DIV>  < D​​IV
    NG-重复=项中的项目
    类=项>
         <! - 我的{{角内容}}在这里 - >
  < / DIV>  < - 这工作: - >
  <! -
  < D​​IV CLASS =项>
    第1项
  < / DIV>
  < D​​IV CLASS =项>
    项目2
  < / DIV>
  < D​​IV CLASS =项>
    项目3
  < / DIV>
  < D​​IV CLASS =项>
    项目4
  < / DIV>
  < D​​IV CLASS =项>
    项目5
  < / DIV>
  < D​​IV CLASS =项>
    项目6
  < / DIV>
  < D​​IV CLASS =项>
    项目7
  < / DIV>
   - >< / DIV>

角指令的基础上:

  myApp.directive('工作空间',['$ rootScope',函数($ rootScope){
    返回{        限制:'A',        链接:功能(范围,元素,ATTRS){            element.ready(函数(){                变种packery =新Packery(元素[0],{
                    的rowHeight:.module施胶机',
                    itemSelector:.item',
                    columnWidth时:.module施胶机
                });                angular.forEach(packery.getItemElements()函数(项目){
                    VAR拖动=新Draggabilly(项目);
                    packery.bindDraggabillyEvents(可拖动);
                });                packery.layout();            });        }
    };
}]);


解决方案

好吧,我找到了答案。

1),我不得不使用一个指令与事件由控制器来接收

2)我不得不添加一个setTimeout的。

  app.directive('lastRepeat',函数(){
    返回功能(范围,元素,ATTRS){
        如果(范围。$最后一个)的setTimeout(函数(){
            。范围$放出('是以lastElement',元,ATTRS);
        },1);
    };
});

I am trying to implement packery in an angularJS application.

When I define the items manually one by one (see the commented html code), Packery works fine.When I try to do the same thing with an ng-repeat loop, packery does not work.

How can I make packery work with ng-repeat in an angularJS template?

The template:

<div class="item-container" workspace>

  <div class="module-sizer"></div>
  <div class="gutter-sizer"></div>

  <div
    ng-repeat="item in items"
    class="item">
         <!--my {{angular content}} here-->
  </div>

  <!-- this works: -->
  <!--
  <div class="item">
    item 1
  </div>
  <div class="item">
    item 2
  </div>
  <div class="item">
    item 3
  </div>
  <div class="item">
    item 4
  </div>
  <div class="item">
    item 5
  </div>
  <div class="item">
    item 6
  </div>
  <div class="item">
    item 7
  </div>
  -->

</div>

The angular directive, based on:http://codepen.io/gruntruk/pen/Cpewt/

myApp.directive('workspace', ['$rootScope', function ($rootScope) {
    return {

        constrain: 'A',

        link: function (scope, element, attrs) {

            element.ready(function () {

                var packery = new Packery(element[0], {
                    rowHeight: '.module-sizer',
                    itemSelector: '.item',
                    columnWidth: '.module-sizer'
                });

                angular.forEach(packery.getItemElements(), function (item) {
                    var draggable = new Draggabilly(item);
                    packery.bindDraggabillyEvents(draggable);
                });

                packery.layout();

            });

        }
    };
}]);
解决方案

Okay, I found the answer.

1) I had to use a directive with an event to be received by the controller

2) I had to add a setTimeout.

app.directive('lastRepeat', function () {
    return function(scope, element, attrs) {
        if (scope.$last) setTimeout(function(){
            scope.$emit('LastElement', element, attrs);
        }, 1);
    };
});
