ng-ng内的模型值-重复不工作

Answer 1

赋给复选框的模型的值是布尔值，无论它是真的还是假的，除非您定义了该值。但同样，它只有2个选项的价值。

因此，与其使用id作为模型属性，不如将其更改为一些可以存储布尔值的属性。为什么不使用'is selected'

<div ng-controller="quoteController" ng-app="MyApp" class="benefits-container">
    <!-- benefits -->
      <div class="benefit" ng-class="{'selected': pe.id}" ng-repeat="pe in policyEnhancementsArr | filter: {type:'optional'}">
          <div class="top">
              <md-checkbox ng-model="pe.isSelected" class="blue"></md-checkbox>
              <h5 class="item">{{pe.name}}</h5>
              <h5 class="prize">{{pe.loading}}</h5>
          </div>
          <div class="bottom">
              <p>{{pe.limitDisplay}}</p>
          </div>
      </div>
  </div>

然后更新一些isSelected值：

...
{
  "id": "PVC022",
  "name": "NCD Protector",
  "limit": null,
  "limitDisplay": "N/A",
  "desc": "<TBC>",
  "type": "optional",
  "loading": 0.0,
  "isSelected": true
},
...
