1：先说指令域scope的@
我觉得描述很费劲，直接用代码来阐述：
angularjs.html
<!doctype html>
<html ng-app='myApp'>
<head>
</head>
<body>
<div ng-controller="listCtrl">
<input type="text" ng-model="t" />
<kid title="{{t}}" > //这个必须指定的，这里的title是指令里scope的@对应的，t就是控制域scope下的
<span>我的angularjs</span>
</kid>
</div>
<script type="text/javascript" src="angular.js"></script>
<script type="text/javascript" src="main05.js"></script>
</body></html>main05.js
var myApp=angular.module('myApp',[]);
myApp.controller('listCtrl',function($scope){
$scope.logchore="motorola";
});
myApp.directive('kid',function(){
return {
'restrict':'E',
scope:{
title:"@"
},
template:'<div >{{title}}</div>'
}
});2：再说说Scope的=
angularjs.html
<!doctype html>
<html ng-app='myApp'>
<head>
</head>
<body>
<div ng-controller="listCtrl">
<input type="text" ng-model="t" />
<kid title="t" > //和上面相比，这个直接赋值等于scope域下的t了
<p>{{title}}</p>
<span>我的angularjs</span>
</kid>
</div>
<script type="text/javascript" src="angular.js"></script>
<script type="text/javascript" src="main05.js"></script>
</body></html>main05.js代码如下：
var myApp=angular.module('myApp',[]);
myApp.controller('listCtrl',function($scope){
$scope.logchore="motorola";
});
myApp.directive('kid',function(){
return {
'restrict':'E',
scope:{
title:"="
},
template:'<div >{{title}}</div>'
}
});3：最后说&，这个是用来方法调用的
angularjs.html代码如下：
<!doctype html>
<html ng-app='myApp'>
<head>
</head>
<body>
<div ng-controller="listCtrl">
<kid flavor="logchore()" ></kid> //先比=，函数赋值的形式，而logchore函数必须是域scope下声明的函数
</div>
<script type="text/javascript" src="angular.js"></script>
<script type="text/javascript" src="main05.js"></script>
</body></html>main05.js代码如下：
var myApp=angular.module('myApp',[]);
myApp.controller('listCtrl',function($scope){
$scope.logchore=function(){
alert('ok');
};
});
myApp.directive('kid',function(){
return {
'restrict':'E',
scope:{
flavor:"&"
},
template:'<div ><button ng-click="flavor()"></button></div>'
}
});如果logchore带有参数，
angularjs.html代码如下：
<!doctype html>
<html ng-app='myApp'>
<head>
</head>
<body>
<div ng-controller="listCtrl">
<kid flavor="logchore(t)" ></kid>
</div>
<script type="text/javascript" src="angular.js"></script>
<script type="text/javascript" src="main05.js"></script>
</body></html>main05.js代码如下：
var myApp=angular.module('myApp',[]);
myApp.controller('listCtrl',function($scope){
$scope.logchore=function(x){
alert(x);
};
});
myApp.directive('kid',function(){
return {
'restrict':'E',
scope:{
flavor:"&"
},
template:'<div > <input type="text" ng-model="v" /> <button ng-click="flavor({t:v})"></button></div>'
}
});
