我编写了一个新指令（showfor），以使用 angular 和 bootstrap 在我的 UI 中启用弹出窗口。“showfor”指令在 html 中有效，但在数据内容中无效。我需要弹出框来显示列表（而不是整个数组）。任何形式的帮助将不胜感激。

代码是：

'use strict';
var isbnApp = angular.module('plunker', []);

isbnApp.directive('mypopover', function() {
  return function(scope, element) {
    element.popover();
  };
});

isbnApp.directive('showfor',function(){
  return{
    restrict:"AEC",
    template:"<li data-ng-repeat='item in records'>{{item.imageType}}</li>"
  };
});

isbnApp.controller('popCtrl', function($scope) {
  $scope.records = [{
    "imageType": "JPEG",
    "rendition": "cover_80"
  }, {
    "imageType": "TIFF",
    "rendition": "cover_20"
  }];

});

<html ng-app="plunker">

    <br />
    <a mypopover="" tabindex="0" role="button" 
    class="btn btn-primary btn-sm" 
    data-container="body" data-toggle="popover" 
    data-html="true" title="<b>Coltrane Data</b>" 
    data-content="<showfor></showfor>">
              Coltrane
      </a>
    <showfor></showfor>
  </div>
</body>

data-content 中的 html 没有被编译，所以我们需要添加一个 angular 指令来执行此操作。

正确的指令取自以下链接，还请查看参考链接

.directive('popover', function($compile, $timeout){
  return {
    restrict: 'A',
    link:function(scope, el, attrs){
      var content = attrs.content; //get the template from the attribute
      var elm = angular.element('<div />'); //create a temporary element
      elm.append(attrs.content); //append the content
      $compile(elm)(scope); //compile 
      $timeout(function() { //Once That is rendered
        el.removeAttr('popover').attr('data-content',elm.html()); //Update the attribute
        el.popover(); //set up popover
       });
    }
  }
})
