显示/隐藏div取决于AngularJS中的下拉选择

Question

我试图根据从下拉列表中选择的内容显示div.例如,如果用户从列表中选择"Cash",则显示Cash div,或者如果用户从列表中选择"Check",则显示Check div

我已经把样本放在一起,但它不完整,需要连线

此外,当用户更改选择时,我还想清除先前的选择,因此当用户返回到之前的选择时,他们不应该看到.

<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>

//控制器:

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


function MyCtrl($scope) {

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

Answer 1

你没有初始化,因为angular app你ng-app首先错过了指令

这是使用的解决方案 ng-if

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.
