1、问题背景
一般情况下，select下都会有option，但是AngularJS中有指令ng-options，就可以实现select下拉框
2、实现源码
- <!DOCTYPE html>
- <html>
- <head>
- <Meta charset="UTF-8">
- <title>AngularJS之下拉框（方式一）</title>
- <script type="text/javascript" src="../js/angular.min.js" ></script>
- <script>
- var app = angular.module("selApp",[]);
- app.controller("selCon",function($scope){
- $scope.options = ["第一季度","第二季度","第三季度","第四季度"];
- });
- </script>
- </head>
- <body>
- <div ng-app="selApp" ng-controller="selCon">
- <select ng-model="selectedName" ng-options="x for x in options" style="width: 180px;">
- </select>
- </div>
- </body>
- </html>
3、问题说明
<select>
<option></option>
</select>
利用指令ng-options，可以省略<option></option>
