本文实例讲述了AngularJS中directive指令使用之事件绑定与指令交互用法。分享给大家供大家参考，具体如下：
AngularJS中模板的使用，事件绑定以及指令与指令之间的交互
<!doctype html>
<html ng-app="myapp">
<head>
<meta charset="utf-8"/>
</head>
<body ng-controller="ShieldController">
<div>
<who></who>
</div>
<div>
<button you-btn></button>
</div>
<theshield reigns>343</theshield>
<theshield reigns>fdhg</theshield>
<theshield rollins>hhh</theshield>
<theshield ambros>kkk</theshield>
</body>
<script src="./js/angular.min.js"></script>
<script>
var app = angular.module('myapp',[]);
/*=======================1. 模板的使用 ========================*/
app.directive('who',function(){
return {
restrict:"E", //元素element 的意思
link:function(scope,element,attrs){
console.log(element);
element[0].innerHTML = 'sdfhkj'; //这个优先级别最高
},
//templateUrl:"param.html", //这个不显示 优先级别最低
template:"<h1>jkdhf</h1>" //这个显示 优先级别其次
};
});
/*=======================2. 事件的绑定 ========================*/
app.directive('youBtn',function(){
return {
restrict:"A", //attribute 属性的意思
link:function(scope,element,attrs){
console.log(element);
element[0].innerHTML = 'my btn';
//事件绑定
element.bind('mouseenter',function(){
element[0].innerHTML = 'your btn';
});
element.bind('mouseleave',function(){
element[0].innerHTML = 'her btn';
});
}
};
});
/*=======================3. 元素 属性 控制器之间的交互========================*/
app.controller('ShieldController',function($scope){
$scope.shieldNames = [];
this.addReigns = function(){
$scope.shieldNames.push("reigns:jjj");
}
this.addRollins = function(){
$scope.shieldNames.push("Rollins:hhh");
}
this.addAmbros = function(){
$scope.shieldNames.push("Ambros:ggg");
}
})
.directive('reigns',function(){
return {
require:"theshield",
link:function(scope,element,attrs,ShieldController){
ShieldController.addReigns();
}
};
})
.directive('rollins',function(){
return {
require:"theshield",
link:function(scope,element,attrs,ShieldController){
ShieldController.addRollins();
}
};
})
.directive('ambros',function(){
return {
require:"theshield",
link:function(scope,element,attrs,ShieldController){
ShieldController.addAmbros();
}
};
})
.directive('theshield',function(){
return {
restrict:"E",
controller:"ShieldController", //指定控制器
scope:{}, //清空该指令处的$scope 值
link:function(scope,element,attrs){
element.bind('mouseenter',function(){ //对于该指令所对应的元素绑定对应的事件
console.log(scope.shieldNames);
});
}
};
});
</script>
</html>
希望本文所述对大家AngularJS程序设计有所帮助。
