AngularJS+RequireJs实现动态加载JS和页面的方案研究

Angularjs 前端之家
前端之家收集整理的这篇文章主要介绍了AngularJS+RequireJs实现动态加载JS和页面的方案研究，前端之家小编觉得挺不错的，现在分享给大家，也给大家做个参考。

摘要：本文是笔者研究了几天的动态加载方案的成果，前台使用的是AngularJS+RequireJs+angular-ui-router+angularAMD。后台使用了SpringMVC+Spring。

1、入口页面

存放地址：src/main/webapp/WEB-INF/view/workflow/workflow.jsp

<!DOCTYPE html>
<html lang="zh">
<head>	  
	<Meta charset="UTF-8">
	<title></title>
	<link href="<%=request.getContextPath()%>/static/css/bootstrap/3.3.5/bootstrap.min.css" rel="stylesheet">
    <link href="<%=request.getContextPath()%>/static/css/sweetalert/sweetalert.css" rel="stylesheet" >
    <link href="<%=request.getContextPath()%>/static/css/angularCommon.css" rel="stylesheet" >
	<script data-main="<%=request.getContextPath()%>/static/js/workflow/app.js" src="<%=request.getContextPath()%>/static/js/bower_components/requirejs/require.js"></script>
</head>
<body>
<div>
<h1>这里是公共头部</h1>
</div>
<div ng-controller = "baseCtrl">
<!--     <button ng-click = "baseClick()">按钮测试</button> -->
	<div ui-view></div>	
</div>
<div>
<h1>这里是公共尾部</h1>
    <button id = "test">根据js内容动态显示</button>
</div>
</body>
</html>
在上面引入了requirejs

2、app.js

require.config({
    paths: {
        "angular": "../angular/1.5.3/angular.min","angular-messages":"../angular/1.5.3/angular-messages.min","angular-locale_zh-cn":"../angular/1.5.3/angular-locale_zh-cn","angular-ui-router": "../bower_components/angular-ui-router/release/angular-ui-router","angularAMD": "../bower_components/angularAMD/angularAMD","ngload": "../bower_components/angularAMD/ngload","sweetalert": "../sweetalert/sweetalert.min","uiBootstrap": "../angular-ui-bootstrap/1.2.4/ui-bootstrap-tpls-1.2.4.min","commonFunction":"../angularCommon/commonFunction","commonValueAndUrl":"../angularCommon/commonValueAndUrl","workFlowCommonModule":"../angularCommon/workFlowCommonModule"
    },shim: {        
		"angular": { exports: "angular" },"workFlowCommonModule": ["angular"],"angular-messages": ["angular"],"angular-locale_zh-cn": ["angular"],"commonValueAndUrl": ["commonFunction"],"angular-ui-router": ["angular"],"uiBootstrap": ["angular-ui-router"],"angularAMD": ["angular"],"ngload": ["angularAMD"]
    }
});
define(["angular","angularAMD","angular-ui-router","sweetalert","uiBootstrap","angular-messages","angular-locale_zh-cn","commonFunction","commonValueAndUrl","workFlowCommonModule"],function (angular,angularAMD) {
    var registerRoutes = function($stateProvider,$urlRouterProvider) {
        $urlRouterProvider.otherwise("/home");
        $stateProvider.state("home",angularAMD.route({
                url: "/home",templateUrl: "../static/js/workflow-view/home-view.js",controllerUrl: "../static/js/workflow/home.js"
            }))
            .state("about",angularAMD.route({
                url: "/about",templateUrl: "../static/js/workflow-view/about-view.js",controllerUrl: "../static/js/workflow/about.js"
            }))
        ;   		
    };        
    var app = angular.module("app",["ui.router",'ui.bootstrap','ngMessages','commonModule']);
    app.config(["$stateProvider","$urlRouterProvider",registerRoutes]);
    app.controller('baseCtrl',function($scope,$uibModal,sendAjaxFactory) {
    	$scope.baseClick = function () {
    		swal("测试按钮")
    	}
    });
    return angularAMD.bootstrap(app);
});

在这里引入了一些需要的模块，其中就一些模块是笔者我自己写的。有的是第三方插件的

这里特别注意，由于SpringMVC会拦截.jsp结尾的文件。所以动态加载 的页面笔者都写到js文件中。如上面的about-view.js和home-view.js.其要动态加载的js文件分别 为about.js和home.js。如果不使用SpringMVc。那么动态加载的页面就可以不用写到js文件中（笔者 的工程中配置了拦截.jsp文件，不拦截.js文件）

3、动态加载的内容：

home.js

define(['app'],function(app)
{
	app.controller('HomeViewController',['$scope',function($scope) {
		document.getElementById("test").onclick = function(){
			swal($scope.title);
        }
	    $scope.title = "Home Home Home Home";
        }
    ]);
});

home-view.js

<div ng-controller="HomeViewController">
<button ui-sref="about">About</button>
<h1>{{ title }}</h1>
<br/>
                   <form name = "registerForm" id = "registerForm" method="post" class="form-horizontal" novalidate >
                       <p class="bg-warning" style = "margin-left:50px;margin-right:50px;"><i class="glyphicon glyphicon-info-sign"></i><span > <b>温馨提示:带<span style="color:red">*</span>为必填项</b></span></p>
