如何在Meteor中设置事件目标的文本和颜色？

我在Meteor模板中加载了一系列项目，如下所示：

I am loading an array of items in a Meteor template like so:

{{#each person}}
  <tr>
    <td><input type="checkbox" class="sendtextckbx" checked></td>
    <td>{{per_firstname}}</td>
    <td>{{per_lastname}}</td>
    <td>{{per_streetaddr1}}</td>
    <td>{{per_streetaddr2}}</td>
    <td>{{per_placename}}</td>
    <td>{{per_stateorprov}}</td>
    <td>{{per_zipcode}}</td>
    <td>{{per_emailaddr}}</td>
    <td class="textnum">{{per_phone}}</td>
    <td class="textmorph">Not sent</td>
    <td>{{per_notes}}</td>
  </tr>
{{/each}}

我想用idtextmorph更新td 点击它的时候。它开始时包含文本未发送，但是当单击td时，我希望它循环浏览其他文本字符串，并相应地更改颜色。

I want to update the td with the id "textmorph" when it is clicked. It starts off containing the text "Not sent" but when the td is clicked, I want it to cycle through other text strings, and change color accordingly, too.

自这个td有1..N个实例，我不能通过类值分配它，因为会有很多共享相同的类（每个人一个）。

Since there are 1..N instances of this td, I can't just assign to it via the class value, as there will be many sharing the same class (one for each person).

我想我可以通过evt.target.value获取当前值，但我不知道如何设置值。这是我的伪代码（也称为疯狂猜测）：

I think I can get the current value via evt.target.value, but I don't know how to set the value. This is my "pseudocode" (also known as a wild guess):

Template.peopleGrid.events({
  'click #btnTextChecked': function() {
    alert('you clicked the btnTextChecked button');
  },
  'click #textmorph': function(evt) {
    var currentText = evt.target.value;
    alert(currentText);
    if (currentText === 'Not sent') {
      evt.target.value = 'Sent';
      evt.target.color = amber;
    }
    else if (currentText === 'Sent') {
      evt.target.value = 'Need Help';
      evt.target.color = red;
    }
    else if (currentText === 'Not sent') {
      evt.target.value = 'Are OK';
      evt.target.color = green;
    }
  }
});

...但我不相信它甚至接近应有的样子。事实上，当我测试它时，〜

...but I'm not confident it's even close to being what it should be. In fact, when I test it out, ~

那么我如何对选定的tds采取行动，改变文字和颜色？该应用程序使用上面的代码运行，但当我点击未发送tds时，会给我一个未定义警告。

So how can I act on the selected tds, changing the text and the color? The app runs with the code above, but gives me an "undefined" alert when I click the "Not sent" tds.
