Question

我已经阅读了有关角度的依赖注入。我想考验一下。但是当我注入模块时，我想将值从一个模块传递到另一个模块（我在控制台上输出

（编辑：解决了它是错误的。未捕获错误：没有模块：sisUser angular.min.js：18它甚至没有评估角度表达式{{2 + 2}}）

让我解释一下这个场景：

的login.html

简单简单登录，要求将两个文本输入用户名和密码输入服务“用户”。

<html lang="en" ng-app="wbsislogin">
<head>
</head>
<body>
<form>
 <fieldset>
    <label>
      <span class="block input-icon input-icon-right">
         <input type="text" class="span12" ng-model="username" placeholder="Username" />
         <i class="icon-user"></i>
        </span>
    </label>

    <label>
      <span class="block input-icon input-icon-right">
          <input type="password" class="span12" ng-model="password" placeholder="Password" />
          <i class="icon-lock"></i>
      </span>
    </label>

    <div class="space"></div>

    <div class="clearfix">
    <label class="inline">
    <input type="checkbox" class="ace" />
        <span class="lbl"> Remember Me</span>
    </label>

    <button ng-click="loginbtn()" class="width-35 pull-right btn btn-small btn-primary">
       <i class="icon-key"></i>
       Login
    </button>
    </div>

    <div class="space-4"></div>
    </fieldset>
</form>
<script src="angular/angular.min.js"></script>
    <script src="wbsis.js"></script>
</body>
</html>

Dash.html

通过注入的服务显示从login.html传递的用户名和密码

<html lang="en" ng-app="wbsislogin">
<head>
</head>
<body>
<p>{{2+2}}</p>
<div ng-controller="ditest">
    {{ usen }} {{ pasw }}
</div>

<script src="angular/angular.min.js"></script>
    <script src="wbsis.js"></script>
</body>
</html>

wbsis.js

var sisUser = angular.module("wbsislogin",[]);
var wbSis = angular.module("wbsis",["wbsislogin"]); // as per the solution 1

sisUser.controller("loginformCtrl",function($scope,user,$log,$location){
$scope.username = "s";
$scope.password = "test2";
$scope.loginbtn = function(){
    user.usern = $scope.username;
    user.passw = $scope.password;
    $log.log(user.usern,user.passw);
    window.location.href='http://sis_frnt.dev/app/dash.html';

}

});

sisUser.factory("user", [function($log){
var user = {
    usern: '',
    passw: ''
};
return user;
}]);
wbSis.controller("ditest", function($scope, $log, user){
$log.log(user.usern,user.passw);
$scope.usen = user.usern;
$scope.pasw = user.passw;

})

请指导我做错的地方。

Answer 1

您需要将模块的名称作为依赖项而不是变量名称传递。

变化：

var sisUser = angular.module("wbsislogin",[]);
var wbSis = angular.module("wbsis",["sisUser"]);

要：

var sisUser = angular.module("wbsislogin",[]);
var wbSis = angular.module("wbsis",["wbsislogin"]);

Angular Dependency Injection，使用服务在模块之间传递值
