筛选器无法正常执行ng-repeat [英] Filter not working ng-repeat

问题描述

我在棱角分明的应用程序中使用 Salvattore ng-repeat中的过滤器选项不起作用. 我认为这是因为 Salvattore 将每个重复的项目包装在单独的div中以形成网格(在我的示例中是div.col-4)

I'm using Salvattore (masonry like grid) in my angular app but the filter option in ng-repeat does not work. I think it's because Salvattore wraps each repeated item in a separate div to make a grid (in my example it's div.col-4)

<input type="text" ng-model="search">
<div class="row grid" salvattore>
  <div class="entry" ng-repeat="e in data | filter:search">
    {{e}}
  </div>
</div>

上面的输出类似于以下内容:

The output of the above is similar to the following:

<div class="row grid" salvattore="" data-columns="3">
  <div class="col-4">
    <div class="entry">e</div>
    <div class="entry">e</div>
  </div>
  <div class="col-4">
    <div class="entry">e</div>
    <div class="entry">e</div>
  </div>
  <div class="col-4">
    ..
  </div>
</div>

我认为这是导致过滤问题的原因...但是我不太确定是不是很诚实:)

I think this is what causes the problem with filtering... but I'm not really sure to be honest :)

问题是: 我应该怎么做才能使其正常工作?我必须创建一个自定义过滤器吗?

我为此创建了一个代码笔: http://codepen.io/anon/pen/MpebNV

I've created a codepen for this: http://codepen.io/anon/pen/MpebNV

谢谢.

推荐答案

我尝试编写自己的指令，它似乎运行得很好. 我在salvattore指令中添加了以下内容.

I tried to write my own directive and it seems to be working quite good. I've added the following to the salvattore directive.

app.directive('salvattore', function($timeout, $window,$filter) {
  return {
    restrict: 'A',
    link: function(scope, element, attrs) {

      // First load (does not work without it
      $timeout(function(){
        element.attr('data-columns', true);
        $window.salvattore.register_grid(element[0]);            
      },0);



    scope.$watch('search', function(newValue, oldValue) {


    // I needed this hack because the grid didn't render properly when $scope.search was empty
    if(newValue=='') {
      var filteredData = scope.data;
      var items = '';
      jQuery.each(filteredData, function(index, entry){
        var ITEM_TEMPLATE = '<div class="entry">{{e}}</div>';
          var content = ITEM_TEMPLATE.replace(/\{\{(\w+)\}\}/g, function (match, g1) {
            switch (g1) {
              case 'e': return entry; break;
            }
          });
          items = items.concat(content);
      });
      jQuery('.grid').html(items);
      $window.salvattore.register_grid(element[0]);
    }


    if (newValue) {
      var filteredData = $filter('filter')(scope.data, scope.search);
      var items = '';
      jQuery.each(filteredData, function(index, entry){
        var ITEM_TEMPLATE = '<div class="entry">{{e}}</div>';
          var content = ITEM_TEMPLATE.replace(/\{\{(\w+)\}\}/g, function (match, g1) {
            switch (g1) {
              case 'e': return entry; break;
            }
          });
          items = items.concat(content);
      });
      jQuery('.grid').html(items);
      $window.salvattore.register_grid(element[0]);
    }

}, true);


    }
  };
});

我知道它看起来很原始，但实际上是什么，但是我也知道它可以更简单.也许有人可以检查一下并有所改善吗?

I know it looks primitive but it is what it is, but I also know it can be simpler. Maybe someone can check this and improve a little bit, please?
