1：先說指令域scope的@
我覺得描述很費勁，直接用代碼來闡述：
angularjs.html
<!doctype html>
<html ng-app='myApp'>
<head>
</head>
<body>
<div ng-controller="listCtrl">
<input type="text" ng-model="t" />
<kid title="{{t}}" > //這個必須指定的，這裏的title是指令裏scope的@對應的，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){
$scope.logchore="motorola";
});
myApp.directive('kid',function(){
return {
'restrict':'E',
scope:{
title:"@"
},
template:'<div >{{title}}</div>'
}
});2：再說說Scope的=
angularjs.html
<!doctype html>
<html ng-app='myApp'>
<head>
</head>
<body>
<div ng-controller="listCtrl">
<input type="text" ng-model="t" />
<kid title="t" > //和上面相比，這個直接賦值等於scope域下的t了
<p>{{title}}</p>
<span>我的angularjs</span>
</kid>
</div>
<script type="text/javascript" src="angular.js"></script>
<script type="text/javascript" src="main05.js"></script>
</body></html>main05.js代碼如下：
var myApp=angular.module('myApp',[]);
myApp.controller('listCtrl',function($scope){
$scope.logchore="motorola";
});
myApp.directive('kid',function(){
return {
'restrict':'E',
scope:{
title:"="
},
template:'<div >{{title}}</div>'
}
});3：最後說&，這個是用來方法調用的
angularjs.html代碼如下：
<!doctype html>
<html ng-app='myApp'>
<head>
</head>
<body>
<div ng-controller="listCtrl">
<kid flavor="logchore()" ></kid> //先比=，函數賦值的形式，而logchore函數必須是域scope下聲明的函數
</div>
<script type="text/javascript" src="angular.js"></script>
<script type="text/javascript" src="main05.js"></script>
</body></html>main05.js代碼如下：
var myApp=angular.module('myApp',[]);
myApp.controller('listCtrl',function($scope){
$scope.logchore=function(){
alert('ok');
};
});
myApp.directive('kid',function(){
return {
'restrict':'E',
scope:{
flavor:"&"
},
template:'<div ><button ng-click="flavor()"></button></div>'
}
});如果logchore帶有參數，
angularjs.html代碼如下：
<!doctype html>
<html ng-app='myApp'>
<head>
</head>
<body>
<div ng-controller="listCtrl">
<kid flavor="logchore(t)" ></kid>
</div>
<script type="text/javascript" src="angular.js"></script>
<script type="text/javascript" src="main05.js"></script>
</body></html>main05.js代碼如下：
var myApp=angular.module('myApp',[]);
myApp.controller('listCtrl',function($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>'
}
});
