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'); $rootScope.relationList = [{id:0,name:'等于'},{id:3,name:'大于'},{id:4,name:'小于'},{id:5,name:'小于等于'},{id:6,name:'大于等于'},{id:2,name:'包含'}]; } } } ];
//AngularJS $emit $broadcast $on
