javascript - angularjs中复选框的实现

Question

我喜欢在 AngularJs 中使用 checkbox 来让用户做出决定。 我无法在我的 AngularJs 代码中捕捉到 checkbox 的状态变化。

我的html代码是

<div ng-show="acceptrequest">
     <label class="switchnmn">
        <input type="checkbox" ng-change="stateChanged()" checked>
        <div class="slidernmn round"></div>
    </label>
    <b style="font-size:15px">I am able to accept customer's any request date.</b>
</div>

AngularJs代码为

    $scope.stateChanged = function (    ) {
        if(){ //If it is checked
          $scope.acceptrequest = true;
       }
       else
          $scope.acceptrequest = false;
    }

当 checkbox 被选中时，$scope.acceptrequest 应该为 true 而 unchecked $scope.acceptrequest 应该是假的。我该怎么做？

我在 css 中实现了复选框是 slider

.switchnmn {
  position: relative;
  display: inline-block;
  width: 60px;
  height: 34px;
}

.switchnmn input {display:none;}

.slidernmn {
  position: absolute;
  cursor: pointer;
  top: 0;
  left: 0;
  right: 0;
  bottom: 0;
  background-color: #ccc;
  -webkit-transition: .4s;
  transition: .4s;
}

.slidernmn:before {
  position: absolute;
  content: "";
  height: 26px;
  width: 26px;
  left: 4px;
  bottom: 4px;
  background-color: white;
  -webkit-transition: .4s;
  transition: .4s;
}

input:checked + .slidernmn {
  background-color: #2196F3;
}

input:focus + .slidernmn {
  box-shadow: 0 0 1px #2196F3;
}

input:checked + .slidernmn:before {
  -webkit-transform: translateX(26px);
  -ms-transform: translateX(26px);
  transform: translateX(26px);
}

/* Rounded sliders */
.slidernmn.round {
  border-radius: 34px;
}

.slidernmn.round:before {
  border-radius: 50%;
}

label, b {
  vertical-align: middle;
}

为复选框声明ng-model，现在您可以在 Controller 中访问复选框的值。

<div ng-show="acceptrequest">
     <label class="switchnmn">
        <input type="checkbox" ng-model="checkBoxValue" ng-change="stateChanged()" checked>
        <div class="slidernmn round"></div>
    </label>
    <b style="font-size:15px">I am able to accept customer's any request date.</b>
</div>

Controller :

 $scope.stateChanged = function (    ) {
        if($scope.checkBoxValue){ 
          $scope.acceptrequest = true;
       }
       else
          $scope.acceptrequest = false;
    }
