Question

以下代码不会在每个setInterval期间呈现任何更改。但是，如果我使用addrecord推送记录，则更改将开始填充。似乎$ apply仅查找记录计数更改。有办法解决这个问题吗？如何在不添加记录的情况下重新渲染模型？

$scope.records = [
    { id:1, title:"The Shawshank Redemption", year:1994, votes:678790, rating:9.2, rank:1},
    { id:2, title:"The Godfather", year:1972, votes:511495, rating:9.2, rank:2},
    { id:3, title:"The Godfather: Part II", year:1974, votes:319352, rating:9.0, rank:3},
    { id:4, title:"The Good, the Bad and the Ugly", year:1966, votes:213030, rating:8.9, rank:4},
    { id:5, title:"My Fair Lady", year:1964, votes:533848, rating:8.9, rank:5},
    { id:6, title:"12 Angry Men", year:1957, votes:164558, rating:8.9, rank:6}
  ];


  $scope.addRecord = function(){
    $scope.records.push({
        title:"New Record",
        rating:999,
        votes:0,
        year:2013
    });
  };

  $scope.random = function(){

    $scope.records.forEach( function(v,k){
        $scope.$apply(
            function(){ v.votes = Math.random(); }
        );
    });

  }

  setInterval( function(){
    console.log('wtf');
    $scope.random(  );
  }, 1000);

更新：此问题是由我用于数据表的webix库引起的。我假设webix也有一个$ apply方法，需要在更新后调用。

<body ng-controller="webixTestController">

<div>
{{records}}
</div>

<div style="width:750px;">
  <div webix-ui view="datatable" webix-data="records" autoheight="true" select="row">
    <div view="column" id="rating" sort="int" css="rating">Rating</div>
    <div view="column" id="year"   sort="int">Year</div>
    <div view="column" id="votes"  sort="int">Votes</div>
    <div view="column" id="title"  sort="string" fillspace="1">Title</div>  
  </div>
</div>

<br>
<button ng-click="addRecord()">Add Row</button>
</body>

Webix要求在数据表上使用refresh（）以使更新的模型生效。

$scope.records.forEach( function(v,k){
    $scope.$apply(
        function(){ v.votes = Math.random(); }
    );
});
$$("table").refresh();

angular $ apply不会使用webix datatable更新模型属性更改
