人生最好的旅行，就是你在一个陌生的地方，发现一种久违的感动。你在看孤独的风景，你在逃避我的真心!
html：
<div ng-controller="mySelectController">
<select ng-model="myField" ng-options="Field.label for Field in names"
ng-change="mySelectControllerChange()">
<option value=''>{{'SELECT.LABEL.VXI.CUSTOM.SELECT' | translate}}</option>
</select>
</div>
<div ng-controller="myRelationController">
<select ng-model="myRelation" ng-options="relation.name for relation in relationList" >
<option value=''>{{'SELECT.LABEL.VXI.CUSTOM.SELECT' | translate}}</option>
</select>
</div>
js：
var mySelectController=['$scope', '$http', '$rootScope', function($scope, $http, $rootScope) {
//$http的method可以是get/delete/head/jsonp/post/put
//$http服务快捷的get请求
//alert('root=='+ACTIVITI.CONFIG.contextRoot);//对应/activiti-explorer/service
$http({
method:'PUT',
url:ACTIVITI.CONFIG.contextRoot +'/getFormFieldList'
})
.success(
function(data,status,headers,config){
//成功加载
$scope.names=data;
})
.error(
function(data,status,headers,config){
//处理错误
//do nothing
}
);
//change
$scope.mySelectControllerChange=function(){
var app=angular.module('activitiModeler',[]);
if($scope.myField.optionGroupId!=null && $scope.myField.optionGroupId!=''){
//有optionGroup
console.log('if');
$rootScope.relationList = [{id:0,name:'等于'},{id:1,name:'不等于'},{id:2,name:'包含'}];
}else{
//没有optionGroup
console.log('else');

//AngularJS $emit $broadcast $on
//change
$scope.mySelectControllerChange=function(){

以上这篇Angularjs 根据一个select的值去设置另一个select的值方法就是小编分享给大家的全部内容了，希望能给大家一个参考，也希望大家多多支持。
