controller && controllAs属性
controller 他会暴露一个API,利⽤用这个API可以在多个指令之间通过依赖注入进行通信
controller($scope,$element,$attrs,$transclude)
controllerAs 是给controller起个别名,方便使用
require 可以将其他指令传递给自己
选项
用法
directiveName
通过驼峰法的命名指定了控制器应该带有哪一条指令,默认会从同一个元素上的指令
^directiveName
在父级查找指令
?directiveName
表示指令是可选的,如果找不到,不需要抛出异常
例子:
index.html
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
</head>
<body>
<div ng-app="myApp">
<div ng-controller="firstController">
<div book-list>
</div>
</div>
</div>
<script src="//cdn.bootcss.com/angular.js/1.4.8/angular.js"></script>
<script type="text/javascript" src="app/index.js"></script>
</body>
</html>
app/index.js
angular.module('myApp', [])
.directive('bookList', function () {
return {
restrict: 'ECAM',
controller: function ($scope) {
$scope.books = [
{
name: 'php'
},
{
name: 'javascript'
},
{
name: 'java'
}
];
$scope.addBook = function(){
}
this.addBook = function(){
// ...
}
},
controllerAs:'bookListController',
template: '<ul><li ng-repeat="book in books">{{book.name}}</li></ul>',
replace:true,
link:function(scope,iEelement,iAttrs,bookListController){
iEelement.on('click',bookListController.addBook)
}
}
})
.controller('firstController', ['$scope', function ($scope) {
// console.log($scope);
}]);
