预选< option>在< select>中在使用ng-repeat时 [英] Preselect <option> in <select> while using ng-repeat

问题描述

我正在使用AngularJS和HTML.如果使用ng-repeat生成我的选项，是否可以在选项标签中预先选择一个选项?例如，请参见下面的代码片段:

I am using AngularJS and HTML. Is there a way to pre-select an option in an option tag if my options are being generated using an ng-repeat? See below code snippet for example:

HTML:

<select class="form-control" id="eventSelectMenu">
    <option ng-repeat="option in allEventData">{{option.name}}</option>
</select>

我已尝试在此处中提出的解决方案此处，但没有已经成功了.

I have tried solutions presented here and here, but none have been successful.

推荐答案

您可以设置任何应预先选择为select的 ngModel

you can set any item which should be pre-selected as value of select's ngModel

console.clear();
angular.module('so-answer', [])
  .controller('ctrl', ['$scope',
    function($scope) {
      $scope.options = [1, 2, 3, 4, 5, 6];
      $scope.selected = 3;
    }
  ])

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="so-answer" ng-controller="ctrl">
  <select ng-model="selected" ng-options="opt for opt in options"></select>
</div>
