我是靠谱客的博主粗暴项链，最近开发中收集的这篇文章主要介绍angularJS 入门基础，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

angular 　　

所有用到的库, 全部用的CDN：

复制代码代码如下:

    <script src="http://cdn.bootcss.com/jquery/2.1.1/jquery.js"></script>

    <script src="http://cdn.bootcss.com/angular.js/1.3.0-beta.13/angular.min.js"></script>

    <link href="http://cdn.bootcss.com/bootstrap/3.3.1/css/bootstrap.css" rel="stylesheet">

    <script src="http://cdn.bootcss.com/underscore.js/1.7.0/underscore-min.js" type="text/javascript"></script>

.angular的数据绑定实例,这个是最基础的,angular的所有枝叶全部从这里开始:.

复制代码代码如下:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml">

           var app = angular.module("app",[]);

    </script>

    <div class="panel panel-default">

        <div class="panel-heading">

            angular最强大的东西,数据的绑定binding

        </div>

        <div class="panel-body">

            <div id="bind" ng-controller="bf">

                <input type="text" ng-model="data" />

                {{data}}

                <script>

                    app.controller("bf", function($scope) {

                        $scope.data = "testData";

                        //$scope.$apply();

                    });

                </script>

            </div>

        </div>

    </div>

</body>

</html>

通过angular,展示数组对应的数据;.

                <script>

                    //angular.module("arr-app", []);

                    function arrCon($scope) {

                        $scope.flag = 0;

                        $scope.bered = function(i) {

                            $scope.flag = i;

                        };

                        $scope.lists = [

                                age : 220

                            }

                        ]

                    };

                </script>

            </div>

        </div>

    </div>

</body>

</html>

.数据过滤器的DEMO：

复制代码代码如下:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml">

<head>

<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />

    <script src="http://cdn.bootcss.com/underscore.js/1.7.0/underscore-min.js" type="text/javascript"></script>

</head>

<body ng-app="app">

    <script type="text/javascript">

           var app = angular.module("app",[]);

    </script>

    <div class="panel panel-default">

        <div class="panel-heading">

            数据过滤器;

        </div>

        <div class="panel-body" ng-controller="filte">

            {{sourCode}}

            <br>

            {{sourCode | up}}

        </div>

        <script>

            function filte($scope) {

                $scope.sourCode = "hehe lala dudu oo zz";

            };

            app.filter("up" ,function() {

                return function(ipt) {

                    return ipt.replace(/ (w)/g,function($0,$1) {

                        return " "+$1.toUpperCase();

                    });

                }

            });

        </script>

    </div>

</body>

</html>

.factory工厂, $provider, service等等都是一样样的, 不要感觉很难, 其实就是看出一个数据模型或者实例就好了;：

复制代码代码如下:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">

    <script src="http://cdn.bootcss.com/angular.js/1.3.0-beta.13/angular.min.js"></script>
    <link href="http://cdn.bootcss.com/bootstrap/3.3.1/css/bootstrap.css" rel="stylesheet">
    <script src="http://cdn.bootcss.com/underscore.js/1.7.0/underscore-min.js" type="text/javascript"></script>
</head>
<body ng-app="app">
    <script type="text/javascript">
           var app = angular.module("app",[]);
    </script>
    <div id="factory" class="panel panel-default">
        <div class="panel-heading">
            angular中的factory就相当于一个公用的实例方法,可以理解为一个多个控制器都可以用的函数;
        </div>
        <div class="panel-body" ng-controller="factory">
            {{json}}
            <script>
                app.factory("ff", function() {
                    return {
                        "noting" : "json"
                    };
                });
                app.controller("factory", function($scope, ff) {
                    $scope.json = ff;
                });
            </script>
        </div>
    </div>
    <div class="panel panel-default">
        <div class="panel-title">
            angular的指令;
        </div>
        <div class="panel-body">
            <heh>do you content for?</heh>
            <script>
                app.directive("heh", function() {
                    return {
                        restrict : "AE",
                        replace : true,
                        transclude : true,
                        template : '<div> <button class="btn-danger" ng-transclude></button></div>'
                    };
                })
            </script>
        </div>
    </div>

</body>
</html>

.ng-switch指令的使用(这个跟模板很想的,就是我们常见的点击隐藏和显示Tab插件的angular首先):：

复制代码代码如下:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml">

<head>

<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />

<title>angular</title>

　　<meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1">

    <script src="http://cdn.bootcss.com/jquery/2.1.1/jquery.js"></script>

    <script src="http://cdn.bootcss.com/angular.js/1.3.0-beta.13/angular.min.js"></script>

    <link href="http://cdn.bootcss.com/bootstrap/3.3.1/css/bootstrap.css" rel="stylesheet">

    <script src="http://cdn.bootcss.com/underscore.js/1.7.0/underscore-min.js" type="text/javascript"></script>

</head>

<body ng-app="app">

    <script type="text/javascript">

           var app = angular.module("app",[]);

    </script>

    <div class="panel panel-default">

        <div class="panel-heading">

            ng-switch的使用

        </div>

        <div class="panel-body" ng-controller="sw">

            <div ng-init="a=2">

                <ul ng-switch on="a">

                    <li ng-switch-when="1">1</li>

                    <li ng-switch-when="2">2</li>

                    <li ng-switch-default>other</li>

                </ul>

              </div>

              <div>

                  <button ng-click="a=1" class="btn btn-primary">test</button>

                  <button ng-click="a=2" class="btn btn-info">test</button>      

                  <button ng-click="a=3" class="btn btn-warning">test</button>

              </div>

        </div>

        <script type="text/javascript">

            app.controller("sw", function($scope) {

            });

        </script>

    </div>

</body>

</html>

ng-src和ng-href;

复制代码代码如下:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml">

<head>

<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />

<title>angular</title>

　　<meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1">

    <script src="http://cdn.bootcss.com/jquery/2.1.1/jquery.js"></script>

    <script src="http://cdn.bootcss.com/angular.js/1.3.0-beta.13/angular.min.js"></script>

    <link href="http://cdn.bootcss.com/bootstrap/3.3.1/css/bootstrap.css" rel="stylesheet">

    <script src="http://cdn.bootcss.com/underscore.js/1.7.0/underscore-min.js" type="text/javascript"></script>

</head>

<body ng-app="app">

    <script type="text/javascript">

           var app = angular.module("app",[]);

    </script>

    <div class="panel panel-default">

        <div class="panel-heading">

            ng-src和ng-href的使用(如果使用src或者href的话,HTML初始化的时候就会加载,肯定是不行的)

        </div>

        <div class="panel-body" ng-controller="srcCon">

            <a ng-href="{{logo}}" >

                <img ng-src="{{logo}}" />

            </a>

        </div>

        <script type="text/javascript">

            app.controller("srcCon", function($scope) {

                $scope.logo = "http://www.mainbo.com/templets/images/logo.gif";

            });

        </script>

    </div>

</body>

</html>

如何操作页面的样式,这个直接改绑定的数据模型就好了：

复制代码代码如下:

    <div class="panel panel-default">

        <div class="panel-heading">

            angular对样式进行操作;(jQ是手动选择元素对元素样式进行操作,angular提供了一种更屌的方法,把元素的属性赋值给一个变量,你只要改变这个变量即可)

        </div>

        <div class="panel-body">

            <hehe id="wh" ng-style="{width: w + 'px', height: h + 'px', backgroundColor: '#364'}">

                hehe--o(^▽^)o哇;

            </hehe>

        </div>

        <script type="text/javascript">

            app.directive("hehe", function() {

                function compile() {

                };

                return {

                    link : function($scope, $element) {

                        var obj = angular.element($element);

                        //obj.find不好用;

                        var add = obj[0].getElementsByClassName("add")[0];

                        var reduce = obj[0].getElementsByClassName("reduce")[0];

                        angular.element(add).bind("click", function(){

                            $scope.h = $scope.h+10;

                            apply();

                        })

                        angular.element(reduce).bind("click", function(){

                            $scope.h = $scope.h-10;

                            apply();

                        });

                        function apply() {

                            $scope.$apply();

                        }

                        return compile;

                    },

                    controller : function($scope) {

                        $scope.w = 200;

                        $scope.h = 50;

                        //$scope.$apply();

                    },

                    restrict: 'AE',

                    replace : true,

                    scope : "=ng-style",

                    transclude : true,

                    template : '<div><div ng-transclude></div><button class="btn btn-default add">+</button><button class="btn btn-default reduce">-</button></div>'

                }

            })

        </script>

    </div>

angular中的模板如何使用,这个要配合路由器使用比较叼:

复制代码代码如下:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml">

<head>

<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />

<title>angular</title>

　　<meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1">

    <script src="http://cdn.bootcss.com/jquery/2.1.1/jquery.js"></script>

    <script src="http://cdn.bootcss.com/angular.js/1.3.0-beta.13/angular.min.js"></script>

    <link href="http://cdn.bootcss.com/bootstrap/3.3.1/css/bootstrap.css" rel="stylesheet">

    <script src="http://cdn.bootcss.com/underscore.js/1.7.0/underscore-min.js" type="text/javascript"></script>

</head>

<body ng-app="app">

    <script type="text/javascript">

           var app = angular.module("app",[]);

    </script>

    <div class="panel panel-default">

        <div class="panel-heading">

            使用模板

        </div>

        <div class="panel-body" ng-controller="ngTpl">

                        <!---这个type要声明准确-->

            <script type="text/ng-template" id="tpl">

                {{ver}}

            </script>

                            <!---tpl是一个定值不是变量，要给变量要在scope中进行定义---->

            <div ng-include src="'tpl'"></div>

            <div class="well">

                <button ng-click="chan()">change</button>

            </div>

        </div>

        <script type="text/javascript">

            app.controller("ngTpl", function($scope) {

                function hehe(str) {

                    str = _.shuffle(str);

                    return str.join("")

                }; 

                $scope.ver = "var——ver--heehe";

                $scope.chan = function() {

                    $scope.ver = hehe( $scope.ver );

                };

            });

        </script>

    </div>

</body>

</html>

如何使用$scope.$watch实时改变绑定界面的模板:

复制代码代码如下:

    </script>

    <div class="panel panel-default">

        <div class="panel-heading">

            <span class="label label-danger">update</span>angular的通知数据更新三种方式$scope.$digest(),$scope.$apply(),以及通过$scope.$watch监听进行更新;

        </div>

        <div class="panel-body" ng-controller="apply">

            {{hehe}}

            <input type="text" ng-model="m0" />

            <div class="well">

                the value set by $scope.$watch ==>> {{wat}}

            </div>

            <br>

            <button ng-click="up()" class="btn btn-default">

                applay;

            </button>

        </div>

        <script type="text/javascript">

            app.controller("apply", function($scope) {

                $scope.hehe = "lll________xxx";

                $scope.m0 = 1;

                ss = $scope;

                $scope.up = function() {

                    $scope.hehe = $scope.m0;

                    //可以,但是给了提示的报错, 谁知道为甚毛?

                    //$scope.$apply();

                    $scope.$digest();

                };

                             //给$scope.m0变量是无效的;

                $scope.$watch("m0", function(va) {

                    $scope.wat = va;

                })

            });

        </script>

    </div>

</body>

</html>

                这些工具方法跟其他库差不多;

                angular.element是anguarLite选择元素的小JQ;

                <br>

                angular.module是模块元素的方法;

setTimeout和setInterval都是经过angular包装过的，返回的是延迟对象的实例:
