Question

我想设置选定的Audio选项，但它不起作用。以下是我的HTML：

<form ng-app='test' ng-controller='testController'>
  <div class="form-group">
    <label for="exampleInputEmail1">Email address</label>
    <select class="form-control" ng-model='event.type'>
        <option disbaled> Select</option>
        <option>IM</option>
        <option>Audio</option>
    </select>
  </div>
  <button type="submit" class="btn btn-default">Submit</button>
</form>

JS：

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

testApp.controller('testController', function ($scope) { 
    $scope.event.type = 'Audio';//not working
});

Fiddle DEMO

有什么想法吗？

Answer 1

使用

$ scope.event = {}如下所示

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

testApp.controller('testController', function ($scope) { 
    $scope.event ={};
    $scope.event.type = 'Audio';//not working
});

OR

testApp.controller('testController', function ($scope) { 
    $scope.event = {'type':'Audio'};//not working
});

Answer 2

在声明对象事件时，代码中存在语法错误。右语法如下。

testApp.controller('testController', function ($scope) { 
    $scope.event ={};
    $scope.event.type = 'Audio';//not working
});

您必须使用ng-selected指向angular来默认选择任何选项。

<option disbaled> Select</option>
<option>IM</option>
<option ng-selected="true">Audio</option>

角度设置选择选项不起作用
