本文實例講述了AngularJS實現的select二級聯動下拉菜單功能。分享給大家供大家參考，具體如下：
<!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>所屬分類： <select ng-model="selected1" ng-options="m.roleName for m in classification1" ng-change="changeClassification(selected1)"> <option value="">-- 請選擇 --</option> </select> <select ng-model="selected2" ng-options="m.roleName for m in classification2"> <option value="">-- 請選擇 --</option> </select></div></body><script> var contantCroleList = [ { "roleName" : "軟件開發", "roleId" : "role1", "children" : [ { "roleName" : "軟件AAA", "roleId" : "role11", "children" : [] }, { "roleName" : "軟件BBB", "roleId" : "role12", "children" : []}, { "roleName" : "軟件CCC", "roleId" : "role12", "children" : []}, { "roleName" : "軟件DDD", "roleId" : "role12", "children" : []}, { "roleName" : "軟件EEE", "roleId" : "role12", "children" : []}, { "roleName" : "軟件FFF", "roleId" : "role12", "children" : []} ]}, { "roleName" : "硬件開發", "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" : "嵌入式開發", "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></html>更多關于AngularJS相關內容感興趣的讀者可查看本站專題：《AngularJS指令操作技巧總結》、《AngularJS入門與進階教程》及《AngularJS MVC架構總結》
