关于ng的Angular JS Action - 更改选择下拉列表

I have a simple table with three rows and two values for each row - date and state:

我有一个简单的表，每行有三行和两个值 - 日期和状态：

<tbody>
   <tr>
      <td>Red</td>
        <td class="lastModified">{{item.redDate}}</td>
        <td class="status"> 
            <select id ="red" class="form-control" ng-change="update();" ng-model="item.redStatus">
              <option value="" disabled="" selected="" class="ng-binding">Please select the value</option>
              <option ng-selected="step.value === item.redStatus"  ng-repeat="(key, step) in steps">{{ step.title }}</option>
            </select>
       </td>
   </tr>
   <tr>Green</tr>
   <tr>
     ....
   </tr>                    
</tbody>

So, simple date and status values for red, green and blue. One in dropdown - status, the second - just output date.

因此，红色，绿色和蓝色的简单日期和状态值。一个在下拉列表中 - 状态，第二个 - 只是输出日期。

On change the select value - i need to update the date with today's date.

在更改选择值时 - 我需要使用今天的日期更新日期。

 `$scope.item.redDate = new Date();`

Is it possible to have one function like ng-change="change();" Can't send with ng-change the ID...

是否有可能有一个函数，如ng-change =“change（）;”无法使用ng发送更改ID ...

Special thanks to Samir Das with help to find the solution ng-change="update(id);":

特别感谢Samir Das帮助找到解决方案ng-change =“update（id）;”：

<select id ="red" class="form-control" ng-change="update(id);" ng-model="item.redStatus">
          <option value="" disabled="" selected="" class="ng-binding">Please select the value</option>
          <option ng-selected="step.value === item.redStatus"  ng-repeat="(key, step) in steps">{{ step.title }}</option>
 </select>

Here is the controller:

这是控制器：

$scope.update = function(id){
    id = event.target.id;
    $scope.item[id+'Date'] = new Date();
 };
