AngularJS笔记整理 内置指令与自定义指令

具体指令参考API 

 

form指令（用于表单验证）

  1. html原生的form表单不能嵌套，而angular封装后可以嵌套，并为form扩展了自动校验，防止重复提交等功能
  2. angular对iinput的元素type进行了扩展，一共提供以下10中类型  text number url email radio checkbox hidden button submit reset 
  3. 内置4种CSS样式
  4. 内置校验器

 

自定义指令

1.实现效果（下拉和展开）

 

HTML

 

 1 <html ng-app='expanderModule'>
 2     <head>
 3         <meta http-equiv="content-type" content="text/html; charset=utf-8" />
 4         <link rel="stylesheet" type="text/css" href="ExpanderSimple.css"/>
 5         <script src="framework/angular-1.3.0.14/angular.js"></script>
 6         <script src="ExpanderSimple.js"></script>
 7     </head>
 8     <body>
 9         <div ng-controller='SomeController'>
10             <expander class='expander' expander-title='title'>
11                 {{text}}
12             </expander>
13         </div>
14     </body>
15 </html>

 

JS

var expanderModule=angular.module('expanderModule', []);
expanderModule.directive('expander', function() {
    return {
        restrict : 'EA',
        replace : true,
        transclude : true,
        scope : {
            title : '=expanderTitle'
        },
        template : '<div>'
                 + '<div class="title" ng-click="toggle()">{{title}}</div>'
                 + '<div class="body" ng-show="showMe" ng-transclude></div>'
                 + '</div>',
        link : function(scope, element, attrs) {
            scope.showMe = false;
            scope.toggle = function() {
                scope.showMe = !scope.showMe;
            }
        }
    }
});
expanderModule.controller('SomeController',function($scope) {
    $scope.title = '点击展开';
    $scope.text = '这里是内部的内容。';
});

 

 

 

2.实现效果

 

HTML

<html ng-app="expanderModule">
    <head>
        <meta http-equiv="content-type" content="text/html; charset=utf-8" />
        <link rel="stylesheet" type="text/css" href="Accordion.css"/>
        <script src="framework/angular-1.3.0.14/angular.js"></script>
        <script src="Accordion.js"></script>
    </head>
    <body ng-controller='SomeController' >
        <accordion>
            <expander class='expander' ng-repeat='expander in expanders' expander-title='expander.title'>
                {{expander.text}}
            </expander>
        </accordion>
    </body>
</html>

 

JS

var expModule=angular.module('expanderModule',[])
expModule.directive('accordion', function() {
    return {
        restrict : 'EA',
        replace : true,
        transclude : true,
        template : '<div ng-transclude></div>',
        controller : function() {
            var expanders = [];
            this.gotOpened = function(selectedExpander) {
                angular.forEach(expanders, function(expander) {
                    if (selectedExpander != expander) {
                        expander.showMe = false;
                    }
                });
            }
            this.addExpander = function(expander) {
                expanders.push(expander);
            }
        }
    }
});

expModule.directive('expander', function() {
    return {
        restrict : 'EA',
        replace : true,
        transclude : true,
        require : '^?accordion',
        scope : {
            title : '=expanderTitle'
        },
        template : '<div>'
                  + '<div class="title" ng-click="toggle()">{{title}}</div>'
                  + '<div class="body" ng-show="showMe" ng-transclude></div>'
                  + '</div>',
        link : function(scope, element, attrs, accordionController) {
            scope.showMe = false;
            accordionController.addExpander(scope);
            scope.toggle = function toggle() {
                scope.showMe = !scope.showMe;
                accordionController.gotOpened(scope);
            }
        }
    }
});

expModule.controller("SomeController",function($scope) {
    $scope.expanders = [{
        title : 'Click me to expand',
        text : 'Hi there folks, I am the content that was hidden but is now shown.'
    }, {
        title : 'Click this',
        text : 'I am even better text than you have seen previously'
    }, {
        title : 'Test',
        text : 'test'
    }];
});
