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：
<!DOCTYPE html>
<html ng-app>
<head lang="en">
<meta charset="UTF-8">
<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" : []},
{ "roleName" : "软件CCC", "roleId" : "role12", "children" : []},
{ "roleName" : "软件DDD", "roleId" : "role12", "children" : []},
{ "roleName" : "软件EEE", "roleId" : "role12", "children" : []},
{ "roleName" : "软件FFF", "roleId" : "role12", "children" : []}
]},
{ "roleName" : "硬件开发", "roleId" : "role2", "children" : [
{ "roleName" : "硬件AAA", "roleId" : "role21", "children" : [] },
{ "roleName" : "硬件BBB", "roleId" : "role22", "children" : []},
{ "roleName" : "硬件CCC", "roleId" : "role23", "children" : []},
{ "roleName" : "硬件DDD", "roleId" : "role24", "children" : []},
{ "roleName" : "硬件EEE", "roleId" : "role25", "children" : []},
{ "roleName" : "硬件FFF", "roleId" : "role26", "children" : []}
]},
{ "roleName" : "嵌入式开发", "roleId" : "role3", "children" : [
{ "roleName" : "嵌入式AAA", "roleId" : "role31", "children" : [] },
{ "roleName" : "嵌入式BBB", "roleId" : "role32", "children" : []},
{ "roleName" : "嵌入式CCC", "roleId" : "role33", "children" : []},
{ "roleName" : "嵌入式DDD", "roleId" : "role34", "children" : []},
{ "roleName" : "嵌入式EEE", "roleId" : "role35", "children" : []},
{ "roleName" : "嵌入式FFF", "roleId" : "role36", "children" : []}
]}
];
function Controller($scope) {
$scope.classification1 = contantCroleList;
$scope.changeClassification = function (selected1) {
$scope.classification2 = selected1.children;
};
}
</script>
