我在这个 plunker

我有在格式（键，计数），默认情况下它们。

I have a text area which has some text in the format of (key,count) in them by default.

我试图实现这一目标是（在计算（）函数）：

What i am trying to achieve is this(in the calc() function):

在该按钮是pressed求和的结果应该显示。

When the button is pressed the results of the summation should be displayed.

我能够从文本区域分成不同的阵列分割数据，但我缺少逻辑添加时的名称相匹配。

I was able to split the data from the textarea into different arrays but i am missing the logic to add when the names match.

编辑：请在我的plunker注意到一些更新

新建角和JavaScript！

New to angular and javascript!

推荐答案

这应该这样做。

JS： -

$scope.calc = function() {
  $scope.users = {};

   $scope.values.split('n').forEach(function(itm){
     var person = itm.split(','),
         name,
         key;

      if(! itm.trim() || !person.length) return;

      name = person[0].trim()
      key = name.toLowerCase();

      $scope.users[key] = $scope.users[key] || {name:name, count:0};
      $scope.users[key].count += +person[1] || 0;
    });
}

HTML： -

HTML:-

<div class="alert alert-success" role="alert">
 <ul>
  <li ng-repeat="(k,user) in users">The total for {{user.name}} is {{user.count}}</li>
 </ul>
</div>
