angularjs - 显示/隐藏div取决于AngularJS中的下拉列表选择

Question

我试图显示一个div，具体取决于从下拉列表中选择的内容。例如，如果用户从列表中选择“现金”显示现金div或用户从列表中选择“检查”显示现金div

我整理了样本，但样本不完整，需要接线

同样，当用户更改选择时，我也想清除先前的选择，因此当用户返回到先前的选择时，他们应该看不到。

<div ng-controller="MyCtrl">
   <div class="col-xs-12">
      <label class="col-xs-6 control-label">Type:</label>
      <div class="col-xs-6">
         <select name="type" ng-model="payment.type" ng-dropdown required ng-change="changeme()" >
            <option ng-option value="Cash">Cash</option>
            <option ng-option value="Check">Check</option>
            <option ng-option value="Money Order">Money Order</option> 
         </select>
      </div>
   </div>
   <div class="col-xs-12" id="cash">
      <div >
         <label class="col-xs-6 control-label">Cash :</label>
         <div class="col-xs-6">
            <input type="number" class="form-control"  ng-model="payment.cash"    />
         </div>
      </div>
    </div>

    <div class="col-xs-12" id="check">
      <div >
         <label class="col-xs-6 control-label">check :</label>
         <div class="col-xs-6">
            <input type="number" class="form-control"  ng-model="payment.check"    />
         </div>
      </div>
    </div>

    <div class="col-xs-12" id="money_order">
      <div >
         <label class="col-xs-6 control-label">money_order :</label>
         <div class="col-xs-6">
            <input type="number" class="form-control"  ng-model="payment.money_order"    />
         </div>
      </div>
    </div>

</div>

// Controller :

var myApp = angular.module('myApp',[]);


function MyCtrl($scope) {

  $scope.changeme = function() {
    alert('here');
  }
}

Answer 1

您没有初始化为angular app，因为您首先错过了ng-app指令

这是使用ng-if的解决方案

DEMO

<div ng-app="myApp" ng-controller="MyCtrl">  // initialize as a angular app

<div class="col-xs-12" id="cash" ng-if="payment.type == 'Cash'"> // this div will show if the value of `payment.type` model equals to `cash`. and so on.
