Question

我的页面上有一个复选框和一个div。

<input type="checkbox" id="Animals" name="Animals" ng-model="ModelData.Animals" 
                            ng-checked="ModelData.Animals == 'A'" />


 <div class="form-group" ng-show="ModelData.Animals == 'A'">

                        <label for="FirstName" class="col-md-9">
                            Are you interested in Animal Liability Coverage?
                        </label>
                        <div class="col-md-3">
                            <label>
                                <input type="radio" id="AnimalLiabCovY" name="AnimalLiabilityCoverageRadio" ng-model="ModelData.AnimalLiabCov"
                                    value="Y" />
                                Yes
                                <input type="radio" id="AnimalLiabCovN" name="AnimalLiabilityCoverageRadio" ng-model="ModelData.AnimalLiabCov"
                                    value="N" />
                                No
                            </label>
                        </div>
  </div>

我想在选中复选框时显示DIV，并在取消选中时隐藏。上面的代码第一次工作正常，即选中复选框时，DIV隐藏取消选中复选框。但是在第一次没有工作之后。选中复选框后，它不会显示DIV。

你有没有尝试过这种方式？这是fiddle它的效果非常好。

<input type="checkbox" id="Animals" name="Animals" ng-model="ModelData.Animals" />
<div class="form-group" ng-show="ModelData.Animals">
  <label for="FirstName" class="col-md-9">
    Are you interested in Animal Liability Coverage?
  </label>
  <div class="col-md-3">
    <label>
      <input type="radio" id="AnimalLiabCovY" name="AnimalLiabilityCoverageRadio" ng-model="ModelData.AnimalLiabCov" value="Y" /> Yes
      <input type="radio" id="AnimalLiabCovN" name="AnimalLiabilityCoverageRadio" ng-model="ModelData.AnimalLiabCov" value="N" /> No
    </label>
  </div>
</div>

我认为您正在寻找ng-true-value和ng-false-value

<div ng-app>
    <div >
        <input type="checkbox" ng-true-value="A" ng-false-value="B" ng-model="check"/>        
    </div>

    <div ng-show="check == 'A'">
        Checked
    </div>
</div>

<强> Fiddle

Answer 3

<body ng-app>
     <label>Wolf: <input type="checkbox" ng-model="Wolf" ng-init="checked=true" /></label><br/>
     <label>Tiger: <input type="checkbox" ng-model="Tiger" ng-init="checked=false" /></label><br/>
     <label>Lion: <input type="checkbox" ng-model="Lion" ng-init="checked=false" /></label><br/> 
     Show when checked:
     <div ng-if="Wolf">
     <span> This is removed when the wolf is checked.
     </span>
     </div>

<div ng-if="Tiger">
    <span> This is removed when the tiger is checked.
    </span>
</div>
<div ng-if="Lion">
    <span> This is removed when the lion is  checked.
    </span>
</div>
</body>

Answer 4

输入类型复选框在ng-model中返回true false，所以我只使用它。工作正常

   <div ng-app>
   <div >
      <input type="checkbox" ng-model="check"/>        
  </div>

  <div ng-show="check == true">
     Checked
  </div>

如何根据角度js中的复选框选择显示/隐藏div
