从Eclipse WTP发布到服务器时如何排除Maven资源？(How do I exclude Maven resources when publishing from Eclipse WTP to a server?)

 问题是，您对所有选择使用相同的范围变量。 您可以将所选选项存储在数组中，如下所示： 
 
 
 
 
 
  
function TestCtrl($scope) {
  $scope.items = [
    { id: 1, class: 1 },
    { id: 2, class: 2 },
    { id: 3, class: 1 },
  ];
  $scope.classes = [
    { name: "class 1", id: 1},
    { name: "class 2", id: 2},
    { name: "class 3", id: 3}
    ];
  };
 
  
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>

<div ng-app>
  <div ng-controller="TestCtrl">
    <div ng-repeat="currentItem in items">
      <select ng-model="selectedClass[$index]" ng-init="selectedClass[$index]=(classes|filter:{id: currentItem.class})[0]" ng-options="class.name for class in classes track by class.id" >
      </select>
      selected class: {{selectedClass[$index]}}
    </div>
  </div>
</div>
 
 
 
 
 
 在这个例子中，我使用变量$ index，它由ng-repeat指令设置。 顾名思义它包含了repeat循环的当前索引。 
 
 UPDATE 
 
 我更新了代码片段，因此它为每个选择输入设置了默认值。 
 
 现在，不同的项目包含一个具有相应类的id的字段。 我用ng-init初始化选择输入。 使用此指令，我设置了selectedClass[$index] ，它是当前项的选定值。 因为我们只将class-id作为项的属性，所以我使用过滤器来查找具有id的相应类对象(classes|filter:{id: currentItem.class})[0] 
 
 要摆脱过滤器，您只需将每个项目的类设置为完整的类对象而不是id。 

The problem is, that you are using the same scope variable for all selections. You could store the selected options in an array too like this:
 
 
 
 
 
  
function TestCtrl($scope) {
  $scope.items = [
    { id: 1, class: 1 },
    { id: 2, class: 2 },
    { id: 3, class: 1 },
  ];
  $scope.classes = [
    { name: "class 1", id: 1},
    { name: "class 2", id: 2},
    { name: "class 3", id: 3}
    ];
  };
 
  
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>

<div ng-app>
  <div ng-controller="TestCtrl">
    <div ng-repeat="currentItem in items">
      <select ng-model="selectedClass[$index]" ng-init="selectedClass[$index]=(classes|filter:{id: currentItem.class})[0]" ng-options="class.name for class in classes track by class.id" >
      </select>
      selected class: {{selectedClass[$index]}}
    </div>
  </div>
</div>
 
 
 
 
 
In this example I take use of the variable $index, which is set by the ng-repeat directive. As the name suggests it contains the current index of the repeat-loop.
 
UPDATE
 
I updated the code-snippet so it sets the default value for each select input.
 
The different items now contain a field with the id of the corresponding class. I initialize the select input with ng-init. With this directive I set selectedClass[$index] which is the selected value for the current item. As we only have the class-id as a property of the items I use a filter to find the corresponding class object with the id (classes|filter:{id: currentItem.class})[0]
 
To get rid of the filter you could just set the class of each item to the full class-object instead of the id.
