角度依赖注入，使用服务在模块之间传递值

Angular Dependency Injection, Passing values between modules using service

本文关键字：模块 之间 服务 依赖 注入      更新时间：2023-09-26

我已经阅读了angular中的依赖项注入。我想测试一下。但当我注入模块时，我想把值从一个模块传递到另一个模块（我在控制台上输出

（编辑：已解决，它给出错误。未捕获错误：无模块：sisUser angular。min.js:18它甚至没有评估角度表达式｛｛2+2｝｝）

让我来解释一下场景：

登录.html

简单的登录要求两个文本输入用户名和密码到服务"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

只显示通过注入的服务从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;
})

请指引我哪里做错了。

您需要将模块的名称作为依赖项而不是变量名称传递。

更改：

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

收件人：

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