angular.element（id）.find（）无法找到子标记

Question

我有一个角色项目，在github上托管。它做了它应该做的事情，但是有一段代码应该执行但是没有执行，这里是行

$scope.tabToggled = function(tab){
    $timeout(function(){
   console.log(angular.element('#'+tab));
        angular.element('#'+tab).find('chartist').each(function(i, e)            {                console.log("Updating");
            e.__chartist__.update();
        });
 }, 100);
 };

在这种情况下，

Updating永远不会被打印出来。

<md-tab ng-repeat="(key, value) in allTheCharts" id="{{key}}" label="{{key}}" md-on-select="tabToggled(key)">'
    <chartist class="ct-chart ct-major-eleventh" chartist-data="value.data" chartist-chart-options="value.options" chartist-chart-type="Bar"></chartist>
</md-tab> 

这是上述代码应该运行并给出输出的标记。这是什么问题？

更好地了解代码。检查回购。仅有2个文件index.html和app.js

Answer 1

最简单的解决方案可能是为chartist元素分配一个ID：

<chartist id="chart-{{key}}" 

在JavaScript中，您可以通过id引用元素：

    $scope.tabToggled = function(tab) {
        console.log(angular.element('#chart-'+tab));
        $('#chart'+tab).each(function(i, e) {
            console.log("Updating");
            e.__chartist__.update();
        });

如果key包含非法字符，则可以改为使用索引：

<md-tab ng-repeat="(key, value) in allTheCharts" md-on-select="tabToggled($index)">
  <chartist id="chart-{{$index}}"
