如何根据角度js中的复选框选择显示/隐藏div [英] how to show/hide a div on the basis of a checkbox selection in angular js

问题描述

我的页面上有一个复选框和一个div。

I have a checkbox and a div on my page.

<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，并在取消选择时隐藏。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。

I want to show the DIV when the checkbox is selected and hide when deselected. For the first time the above code workd fine ie when checkbox is selected and DIV hides on deselecting the checkbox. But after the first time its not working. It does not show the DIV after selecting the checkbox.

<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">
