AngularJS使用ng-repeat指令实现下拉框
AngularJs 的 ng-repeat 让我们非常方便的遍历数组生成 Dom 元素，但是使用不当也会有性能问题。下面给大家分享在项目中使用ng-repeat指令实现下拉框。
1、问题背景
select下拉框里option组装成下拉框，这里利用ng-repeat指令来创建
2、实现源码
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>AngularJS之下拉框（方式二）</title>
<script type="text/javascript" src="../js/angular.min.js" ></script>
<script>
var app = angular.module("secondApp",[]);
app.controller("secondCon",function($scope){
$scope.trees = ["松树","樟树","枫树","枣树","桃树"];
});
</script>
</head>
<body>
<div ng-app="secondApp" ng-controller="secondCon">
<select style="width: 200px;">
<option ng-repeat="tree in trees">{{tree}}</option>
</select>
</div>
</body>
</html>3、问题说明
ng-repeat指令可以重复数据
