冉冉升起的如银的炊烟，那更古沉默永不停息的小溪，那驮着夕阳缓缓独行的老牛，一方方秧田像棋盘格子，绿绒绒的秧苗，织成一幅幅地毯，远远地伸向天际；丛丛绿树掩映着青砖红瓦的房屋。春天，故乡的松树林依然郁郁苍苍，映山红却已开遍山丘。
本文实例讲述了AngularJS实现的select二级联动下拉菜单功能。分享给大家供大家参考，具体如下：

<title></title>
</head>
<script src="../script/angular.js"></script>
<body ng-controller="Controller">
<div>所属分类：
<select ng-model="selected1" ng-options="m.roleName for m in classification1" ng-change="changeClassification(selected1)">
<option value="">-- 请选择 --</option>
</select>
<select ng-model="selected2" ng-options="m.roleName for m in classification2">
<option value="">-- 请选择 --</option>
</select>
</div>
</body>
<script>
var contantCroleList = [
{ "roleName" : "软件开发", "roleId" : "role1", "children" : [
{ "roleName" : "软件AAA", "roleId" : "role11", "children" : [] },
{ "roleName" : "软件BBB", "roleId" : "role12", "children" : []},

]}
];
function Controller($scope) {
$scope.classification1 = contantCroleList;
$scope.changeClassification = function (selected1) {
$scope.classification2 = selected1.children;
};
}
</script>
