如何在AngularJS中阅读csv文件内容？

Question

我想阅读一个csv文件,并使用AngularJS和HTML5获取其内容.我想将csv文件的内容放在$ scope中.

我在我的HTML中有这个代码

 <table align="center" >
            <tr class="borderless">
                <td>Choose .csv file</td>
                <td><input type="file" name="readCsvFile" id="readCsvFile" accept=".csv"> </td>
                <td><input type="button" value="Upload" ng-click="uploadCsvFile()"></td>
            </tr>
 </table>

使用自定义指令:

app.directive('fileReader', function() {
  return {
    scope: {
      fileReader:"="
    },
    link: function(scope, element) {
      $(element).on('change', function(changeEvent) {
        var files = changeEvent.target.files;
        if (files.length) {
          var r = new FileReader();
          r.onload = function(e) {
              var contents = e.target.result;
              scope.$apply(function () {
                scope.fileReader = contents;
              });
          };

          r.readAsText(files[0]);
        }
      });
    }
  };
});
