我无法从 Controller 中的对象将数据放入 ng-model View 中。
View 1:
<input type="text" class="user-input" name="profile.firstname" ng-model="profile.firstname" ng-minlength="2" required pattern=".{2,}" placeholder="E.g. Anvika" title="Please enter atleast 2 characters">
当我在 VIEW2 中单击一个按钮时，它会触发一个函数(比如函数“test”)。
View 2
<input type="submit" ng-click="register.test()" ui-sref="doctorRegister" value="Profile">
Controller :
var app = angular.module('app');
app.controller('registerController', ['$scope', 'tempDataStorageService', function ($scope, tempDataStorageService) {
var register = this;
register.doctor = {};
register.test = function () {
register.refreshProfile = tempDataStorageService.get(register.doctor.profile);
//console.log(register.refreshProfile);
var a = register.refreshProfile.firstname;
console.log(a);
}
}
临时数据存储服务:
var app = angular.module('app');
app.factory('tempDataStorageService', function() {
var savedData = {};
function set(data) {
savedData = data;
}
function get() {
return savedData;
}
return {
set: set,
get: get
}
});
编辑:如果有帮助，我也尝试显示 Controller 的声明。
我怎样才能做到当我点击 VIEW2 上的 Profile 按钮时，它会用数据填充 VIEW1？

JS:
var app = angular.module('plunker', []);
app.controller('MainCtrl', ['tempDataStorageService', function(tempDataStorageService) {
var register = this;
register.firstName = "";
register.storedData = tempDataStorageService;
register.test = function () {
tempDataStorageService.setName(register.firstName);
}
}]);
app.factory('tempDataStorageService', function() {
// The service object
var profile = {};
profile.doctorFirstName = "No doctor data stored";
//The functions
profile.setName = function(data) {
profile.doctorFirstName = data;
}
profile.getName = function() {
return profile.doctorFirstName;
}
// return the service object
return profile;
});
