<script>
angular.module('app',[])
.controller('UserCtrl',function($scope){
$scope.user={
isShowImg:true,
showicon:true,
icon:"images/demo.jpg",
uname:"",
pwd:"",
zw:"2",
sex:"1",
aihao:[1,3]
};
$scope.isChecked=function(n){
var isok=false;
for(var i=0;i<$scope.user.aihao.length;i++){
if(n==$scope.user.aihao[i]){
isok=true;
break;
}
}
return isok;
};
$scope.register=function(u){
console.log(u);
}
}); </script>

2.angular与element（1）
<!DOCTYPE html>
<html>
<head lang="en">
<meta charset="UTF-8">
<title></title>
<link rel="stylesheet" href="http://cdn.static.runoob.com/libs/foundation/5.5.3/css/foundation.min.css">
</head>
<body>
<div ng-app="app">
<div enter leave>我在这</div>
</div>
</body>
<script src="js/angular.min.js"></script>
<script>
var app=angular.module('app',[]);
app.directive('enter',function(){
return function(scope,element,attrs){
element.bind('mouseenter',function(){
element.addClass('alert-box');
})
}
});
app.directive('leave',function(){
return function(scope,element,attrs){
element.bind('mouseleave',function(){
element.removeClass('alert-box');
})
}
});
</script>
</html>
angular与element（2）
<!DOCTYPE html>
<html>
<head lang="en">
<meta charset="UTF-8">
<title></title>
<link rel="stylesheet" href="css/foundation.min.css">
</head>
<body>
<div ng-app="app">
<hello></hello>
</div>
</body>
<script src="js/angular.min.js"></script>
<script>
var app=angular.module('app',[]);
app.directive('hello',function(){
return {
restrict:"E",
template:'<div><input ng-model="txt"></div><div>{{txt}}</div>',
link:function(scope,element){
scope.$watch('txt',function(newVal){//监听
if(newVal==='error'){
element.addClass('alert-box alert')
}
})
}
}
});
</script>
</html>
3.自定义HTML组件
<!DOCTYPE html>
<html>
<head lang="en">
<meta charset="UTF-8">
<title></title>
<link rel="stylesheet" href="css/bootstrap.min.css"/>
</head>
<body>
<p>p:restrict含义(A属性，E标签元素（结合template插入），C类名)与应用，replace使用，template使用</p>
<div ng-app="app">
<div hello class="leiming"></div>
</div>
</body>
<script src="js/angular.min.js"></script>
<script>
var app=angular.module('app',[]);
app.directive('hello',function(){
// return {
// restrict:'E',//自定义HTML标签，在dom中显示标签名为hello
// replace:true,//默认false，替换掉自定义的directive名称，即把hello替换为div
// template:'<div>hello Angularjs</div>'
// };
return {
restrict:'A',
link:function(){
alert("我是属性")
}
};
});
app.directive('leiming',function(){
return {
restrict:'C',
link:function(){
alert("我是类名")
}
};
});
</script>
</html>
4.directive与controller
<!DOCTYPE html>
<html>
<head lang="en">
<meta charset="UTF-8">
<title></title>
</head>
<body>
<!--<p>controller属性使用，link使用，directive中调用controller的方法</p>-->
<div ng-app="app">
<!--<div ng-controller="AppCtrl">-->
<!--<div enter="loadMoreData()">加载数据</div>-->
<!--</div>-->
<food apple orange banana>所有食物</food>
<food apple banana>所有食物</food>
</div>
</body>
<script src="js/angular.min.js"></script>
<script>
var app=angular.module('app',[]);
//app.controller('AppCtrl',function($scope){
// $scope.loadMoreData=function(){
// alert("正在加载数据...")
// };
// $scope.delData=function(){
// alert("正在删除数据...")
// }
//});
//app.directive('enter',function(){
// return function(scope,element,attrs){
// element.bind('mouseenter',function(){
// //scope.loadMoreData();
// //scope.$apply('loadMoreData()');
// scope.$apply(attrs.enter);
// })
// }
//});
app.directive('food',function(){
return {
restrict:'E',
scope:{},
controller:function($scope){
$scope.foods=[];
this.addApple=function(){
$scope.foods.push('Apple');
};
this.addOrange=function(){
$scope.foods.push('Orange');
};
this.addBanana=function(){
$scope.foods.push('Banana');
}
},
link:function(scope,element,attrs){
element.bind('mouseenter',function(){
console.log(scope.foods);
});
}
}
});
app.directive('apple',function(){
return {
require:'food',
link:function(scope,element,attrs,foodCtrl){
foodCtrl.addApple();
}
}
});
app.directive('orange',function(){
return {
require:'food',
link:function(scope,element,attrs,foodCtrl){
foodCtrl.addOrange();
}
}
});
app.directive('banana',function(){
return {
require:'food',
link:function(scope,element,attrs,foodCtrl){
foodCtrl.addBanana();
}
}
});
</script>
