1.angular.bind

var self = {name: 'boy'};
var f = angular.bind(self, function (age) { alert(this.name + ' is ' + age + ' !')});
 f(12);

2、angular.bootstrap

  var app = angular.module('demo', [])
  .controller('WelcomeController', function($scope) {
      $scope.greeting = 'Welcome!';
  });
  angular.bootstrap(document, ['demo']);

3、angular.copy

使用angular.copy拷贝后会指向一个新地址

4、angular.element

angular.element(document.getElementById('ddd')).addClass('ccc')

5、angular.equal(pram1,pram2);

angular.equal("a","a");//true
console.log(angular.equals(true,1));  //false 不能进行强转化
var a={a:111};
var b={a:111};
console.log(angular.equals(a, b));    //true

6、angular.forEach（Arr，fn，[context]）

    //对象遍历
    var values = {name: 'misko', gender: 'male'};
    var log = [];
    angular.forEach(values, function(value, key) {
        log.push(key + ': ' + value);
    });
    console.log(log);
    //["name: misko", "gender: male"]

   var values = {name: 'misko', gender: 'male'};

var log = [];
   angular.forEach(values, function(value, key) {
        this.push(key + ': ' + value);
    }，log);
//["name: misko", "gender: male"]

    //数组遍历
    var values = [1,2,3];
    var log = [];
    angular.forEach(values, function(value, key) {
        log.push(key + ': ' + value);
    });
    console.log(log);

7、angular.fromJson

    var json = '{"name":"liSi", "password":"321"}';
    var jsonArr = '[{"name":"zhangSan", "password":"123"},{"name":"liSi", "password":"321"}]';
    var obj = angular.fromJson(json);
    console.log(obj);
    var objArr = angular.fromJson(jsonArr);
    console.log(objArr);

8、angular.identity

function getResult(fn, input) {
  return (fn || angular.identity)(input);
};
getResult(function(n) { return n * 2; }, 21);   // returns 42
getResult(null, 21);                            // returns 21
getResult(undefined, 21);                       // returns 21

Module

1、form

<script src="angular-1.3.0.js"></script>
<style>
        .my-form {
            transition:all linear 0.5s;
            background: transparent;
        }
        .my-form.ng-invalid {
            background: red;
        }
</style>
<script>
    angular.module('formExample', [])
        .controller('FormController', ['$scope', function($scope) {
            $scope.userType = 'guest';
        }]);
</script>

<form name="myForm" ng-controller="FormController" class="my-form">
    userType: <input name="input" ng-model="userType" required>
    <span class="error" ng-show="myForm.input.$error.required">Required!</span><br>
    <code>userType = {{userType}}</code><br>
    <code>myForm.input.$valid = {{myForm.input.$valid}}</code><br>
    <code>myForm.input.$error = {{myForm.input.$error}}</code><br>
    <code>myForm.$valid = {{myForm.$valid}}</code><br>
    <code>myForm.$error.required = {{!!myForm.$error.required}}</code><br>
</form>

directive

这里需要自己配置一下angular链接和ng-app才能执行

1.input type="checkbox"

<script type="text/javascript">
        angular.module('checkboxExample', [])
            .controller('ExampleController', ['$scope', function ($scope) {
                $scope.value1 = true;
                $scope.value2 = 'YES'
            }]);
</script>
<form name="myForm" ng-controller="ExampleController">
    Value1: <input type="checkbox" ng-model="value1"> <br />
    Value2: <input type="checkbox" ng-model="value2"
                   ng-true-value="'YES'" ng-false-value="'NO'"> <br />
    <tt>value1 = {{value1}}</tt><br />
