对我来说,我有一个非常愚蠢的,我一整天都在看这段代码而没有结果。
我有一个简单的文本框,它通过控制器并更新服务中的变量(该服务最终会从其他地方获取/更新数据)。
目前,我能够一直检索变量值到视图并且它可以正常工作,但是文本框无法更新服务中的变量,以便再次在视图中显示新的变量值....
我非常感谢任何帮助,希望我有道理!
// APP/APP.JS
(function(){
var app = angular.module('appMod', ['ngRoute', 'ngAnimate']);
app.config(function ($routeProvider) {
$routeProvider
.when('/',
{
controller: 'introController',
templateUrl: 'app/partials/intro.html'
})
.otherwise({ redirectTo: '/' });
});
app.controller('nameController', function($scope, dataService) {
var nameValue;
this.name = dataService.getName();
this.submitName = function(nameVal) {
nameValue = this.nameCtrl.nameVal;
dataService.setName(nameValue);
};
});
app.controller('introController', function($scope, dataService) {
this.name = dataService.getName();
});
app.service('dataService', function () {
var name = "f";
this.getName = function() {
return name;
};
this.setName = function(nameVal) {
name = nameVal;
};
});
})();

答案 0 :(得分:0)
您需要在输入
上绑定名称而不是nameVal然后在你的setName调用中传递它,我不认为那里需要其余的代码,你也可以删除nameValue var。
this.submitName = function() {
dataService.setName(this.name);
};
nameValue var是控制器的本地变量,并且在$ scope上不可用于绑定到您的视图,所以即使您正在更改它,视图也不知道它,因为它看不到var。 / p>
