npm install angular

以下走示例仅基于angular1.3.0,高版本不兼容

架子

function Aaa($scope,$rootScope){ //$rootScope全局 ,函数的形参
    $scope.name = 'hello' /* M */
    $rootScope.age = 20; //$scope,只会有Aaa起作用
}}            
<div ng-controller="Aaa" ng-app>
    <p>{{name}}</p>
    <p>{{age}}</p>
</div>

angularJs的MVC方式

数据的挂载
ng-controller
双大括号表达式

angularJs的作用域

$scope
$rootScope
依赖注入
服务

angularJs的指令系统

ng- 指令; ng-app:初始化;,不写则不会执行;初始化可以写到任何位置,按标签来启动 ; ng-controller :控制器连接桥梁;

angular双向数据绑定

MVVM; 当M(数据)发生改变时,会自动让视图改变,而视图改变,可以让相关的数据改变,
$timeout
ng-click
ng-model

数据影响视图

function Aaa($scope,$timeout){ //注入$timeout
    $scope.name = 'hello' /* M */
    $timeout(function(){
        $scope.name = 'hi' /* M */
    },2000)//改变后视图也改 ;

    $scope.show = function () {
        $scope.name = 'hahahas'
    }
}
<div ng-controller="Aaa" ng-click="show()">  <!-- C -->  <
    <p>
        {{name}}  <!-- V -->
    </p>
</div>

视图影响数据

function Aaa($scope,$timeout){ //注入$timeout
    $scope.name = 'hello' /* M */
    $timeout(function(){
        $scope.name = 'hi' /* M */
    },2000)//改变后视图也改 ;

    $scope.show = function () {
        $scope.name = 'hahahas'
    }
}
<div ng-controller="Aaa">  <!-- C -->
    <input type="text" name="" id="" ng-model="name"/>  <!-- 输入框改东西会影响到p标签里的name,ng-model指的即为数据 ; -->
    <p>
        {{name}}  <!-- V -->
    </p>
</div>

过滤器

currency

$watch

监听数据变化
三个参数
function Aaa($scope,$timeout){ //注入$timeout
    $scope.iphone = {
        money:50,
        num:1,
        fre:10
    }
    $scope.sum = function(){
        return $scope.iphone.money * $scope.iphone.num
    }
    $scope.$watch('iphone.money',function(newVal,oldVal){ 
    //  ('字符串(不加$scope)',function(){} ,true) //第三个参数针对集合监听,注意字符串也必须是集合;
    //  console.log(newVal); //监听时iphone.money改变时触发 ;
    //  console.log(oldVal); //监听时iphone.money改变时触发 ;
    // newVal :新值,
    // oldVal:  旧值
    },true) 


    $scope.$watch($scope.sum,function(newVal,oldVal){
        console.log(newVal); //监听时iphone.money改变时触发 ;
        console.log(oldVal); //监听时iphone.money改变时触发 ;
        $scope.iphone.fre =   newVal>=100?0:10; //当大于100时运费免费
    })
}
<div ng-controller="Aaa">  <!-- C -->
    <input type="text" name="" id="" ng-model="name"/>  <!-- 输入框改东西会影响到p标签里的name,ng-model指的即为数据 ; -->
    <p>
       价格:<input type="text" name="" id="" ng-model="iphone.money"/>
    </p>
    <p>个数:<input type="text" name="" id="" ng-model="iphone.num"/></p>
    <p>费用:<span>{{sum()| currency:'¥' }}</span></p>
    <p>运费:<span>{{iphone.fre | currency:'¥'}}</span></p>  <!-- html里的代码不需要写$scope -->
    <p>总额度:<span>{{sum()+iphone.fre | currency:'¥'}}</span></p>
</div>



angularJs的模块化

angular.module
压缩的问题

angularJs的工具方法

angular.bind :是当于$.proxy,改this指向;
angular.copy :复制
angular.extend : 对象的复制,相当于继承
var m1 = angular.module('myApp',[]);
    m1.controller('Aaa',['$scope',function($scope){  //m1.controller控制器(函数名,函数内容)
        $scope.name = 'hello'
    }])
function show(n1,n2){
    alert(n1)
    alert(n2)
    alert(this)
}
angular.bind(document,show,3)(4)  //改this为document指向;

var a = { name:'hello' },b = { age:20 };
    var c = angular.copy(a)
    var d = angular.copy(a,b) //a把报有值给了b,相当于 b复制了a;
    console.log(d);


var a = { name:'hello' },b = { age:20 };
    var c = angular.extend(a,b)  //相当于把a 、b 都给了a
    console.log(a);  //所以此时 c == a;

angularJs的工具方法

angular.isArray
angular.isDate
angular.isDefined
angular.isUndefined
angular.isFunction
angular.isNumber
angular.isObject
angular.isString
angular.isElement
angular.version
angular.equals
angular.forEach
angular.fromJson/toJson
angular.identity/noop:传什么输出即什么/空函数
angular.lowercase/uppercase :大小写
angular.element:获取元素,相当于$
angular.bootstrap:初始化的一种方式 动态初始化代替ng-app
angular.injector:注册器,主要在内部使用,外部较少使用
function noop(){} //空函数
//可能的作用如下:如果不传可能出问题;
function transformer(transformationFn,value){
    return (transformationFn || angular.identity(value)) ;
}

//不使用ng-app时
document.onclick = function () {
    var _div = document.getElementsByTagName('div')
    angular.bootstrap(_div[0],['myApp1'])
    angular.bootstrap(_div[1],['myApp2']) //分别初始化调用,(目标元素,加载模块)
  //angular.bootstrap(document,['myApp']) //初始化在document上, 想要触发时再触发发;
}

var _div = document.getElementById('div1')
angular.element(_div).css('background','red')

$scope

$scope.$watch
$scope.$apply

angular.module

controller
run
function Aaa($scope) { //不注入$timeout
    $scope.name = 'hello'
    setTimeout(function(){  //使用原生
        $scope.$apply(function () {  //可以监听函数下的数据是否变化,如果有变化就会影响到视图,可以在第三方的库或原生js直接使用;
            $scope.name = 123
        })
    },2000)
}



angularJs的过滤器

currency
number
lowercase/uppercase
json
limitTo
date
orderBy
filter

过滤器扩展部分

可组合使用过滤器
JS中使用过滤器
$scope/$rootScope/$timeout
$filter
    var m1 = angular.module('myApp',[]);  //模块的写法 模块的写法要带出参数
        m1.controller('Aaa',['$scope',function($scope){
            $scope.name = '456456456.0322021'
            $scope.name = 'heoow'
            $scope.name = {'name':'elmok','age':30}
            $scope.name = ['a','b','c']
            $scope.name ='1231235'
            $scope.name = [   //orderBy,针对下面这种形式,数组里json
                {color:'red',age:20},
                {color:'yeloo',age:22},
                {color:'yeloo',age:23},
                {color:'#f9f9f9',age:24}
            ]
        }])
<div ng-controller="Aaa"> 
    {{name | currency:"¥"}}
    {{name | number :2}} //number只加分隔符 有小数情况下只截取前3位 后面参数代表要保留几位小数点;
    {{name | uppercase}}
    <pre>{{name | json}}</pre> //格式化 注意,需要在pre标签里
    {{name | limitTo:2}}  //后面即代表需要截取几位
    {{ name | date:'yyyy-MM-dd HH:mm:ss Z'}}  //Jan 1, 1970
    {{name | orderBy:'age':true}}  //加true 相反排序 
    {{name |filter:'l'}}   //  针对数据中的value值  加true==整个value值匹配,不能字符匹配
    
</div>

自定义过滤器

angular.module
controller/run
filter
var m1 = angular.module('myApp',[]);

//模块对象下的方法filter调用; 创建首字母变大写的过滤器;
m1.filter('filterUppercase',function(){
    return function (str,num) {
        console.log(num); //2,可找到num了,所以可做下一步操作;
        console.log(str);//返回的是传入的
        return str.charAt(0).toUpperCase() + str.substring(1)
    }
})

//使用
m1.controller('Aaa',['$scope','$filter',function($scope,$filter){
/*
    $scope.name = '456456456.0322021'
    $scope.name = 'heoow'
    $scope.name = {'name':'elmok','age':30}
    $scope.name = ['a','b','c']
    $scope.name ='1231235'
    $scope.name = $filter('uppercase')('heoow') //转大写操作;
    $scope.name = $filter('number')('123456') //转大写操作;
    $scope.name = $filter('number')('123456.12312',1) //转大写操作; //后面为限制小数点个数
    $scope.name = $filter('date')('4512312123','hh') //转日期;
*/
    $scope.name = $filter('filterUppercase')('heoow','2')
}])

ng-repeat指令

遍历集合, 通过in的方式遍历每一项, $index :$index每一项返回index
$first :$first 第一项返回true,其它返回false
$middle: $middle,除非第一项与最后一项,其它返真
$last: $last 最后一项返回true,其它返回true;
$even :偶数行返回true,奇数行返回false
$odd :与上相反
ng-repeat-start : 只循环一个li
ng-repeat-end
var m1 = angular.module('myApp',[])
    m1.controller('Aaa',['$scope',function($scope){
        $scope.dataList = [
                'aaa','bbb','ccc'
        ]
    }])
 <li ng-repeat="d in dataList">{{d}}</li> <!-- d 循环中的每一项 -->

表格小例

var m1 = angular.module('myApp',[])
m1.controller('Aaa',['$scope','$filter',function($scope,$filter){
    var oriArr = [
        {name:'red',age:'29'},
        {name:'black',age:'22'},
        {name:'blue',age:'23'},
        {name:'yellow',age:'24'}
    ];;
    $scope.dataList =oriArr;
    $scope.fnSort = function (arg) {
        //函数挂属性:分别有开关,加属性;一次真一次假,
        arguments.callee['fnSort' + arg] = !arguments.callee['fnSort' + arg];
        $scope.dataList = $filter('orderBy')($scope.dataList, arg, arguments.callee['fnSort' + arg]);
        //排序完结果重新赋值
    }
    $scope.fnfilter = function (){
        $scope.dataList = $filter('filter')(oriArr,$scope.filterVal)
    }
}])
<div ng-controller="Aaa">
    <input type="text" name="" id="" ng-model="filterVal"/> <input type="button" value="Search" ng-click="fnfilter()"/>
    <table border="1">
        <tr>
            <th ng-click="fnSort('name')">姓名</th>
            <th ng-click="fnSort('age')">年龄</th>
        </tr>
        <tr ng-repeat="d in dataList">
            <td>{{d.name}}</td>
            <td>{{d.age}}</td>
        </tr>
    </table>
</div>

隔行变色等;

var m1 = angular.module('myApp',[])
m1.controller('Aaa',['$scope',function($scope){
    $scope.dataList = [
        'aaa','bbb','ccc','ddd','eee','ggg'
    ]
}])
<div ng-controller="Aaa">
    <ul>
    <li ng-repeat="d in dataList">{{$index}}</li> <!-- d 循环中的每一项 -->   $index每一项返回index        
        <li class="{{$even ? 'active' : ''}}" ng-repeat="d in dataList">{{$odd}}</li>
        <li class="{{$even ? 'active' : ''}}" ng-repeat="d in dataList">{{d}}</li>
    </ul>
    
    <!--需求,下面的循环,不改变结构-->
    <div ng-repeat-start="d in dataList">{{d}}</div>
    <p>{{d}}</p>
    <div ng-repeat-end>{{d}}</div>
</div>
