指令与控制器交互，指令与指令交互
慕课网《AngularJS实战》–指令3笔记，点击打开链接
一、不同指令对应不同控制器方法（指令的复用）
Directive&Controller.js
var myModule = angular.module("MyModule", []);
myModule.controller('MyCtrl', ['$scope', function($scope){
$scope.loadData=function(){
console.log("加载数据中...");
}
}]);
myModule.controller('MyCtrl2', ['$scope', function($scope){
$scope.loadData2=function(){
console.log("加载数据中...22222");
}
}]);
myModule.directive("loader", function() {
return {
restrict:"AE",
link:function(scope,element,attrs){
element.bind('mouseenter', function(event) {
//scope.loadData();
// scope.$apply("loadData()");
// 注意这里的坑，howToLoad会被转换成小写的howtoload
scope.$apply(attrs.howtoload);
});
}
}
});Directive&Controller.html
<html ng-app="MyModule">
<head>
<meta charset="utf-8">
head>
<body>
<div ng-controller="MyCtrl">
<loader howToLoad="loadData()">滑动加载loader>
div>
<div ng-controller="MyCtrl2">
<loader howToLoad="loadData2()">滑动加载loader>
div>
body>
<script src="framework/angular-1.3.0.14/angular.js">script>
<script src="Directive&Controller.js">script>
html>二、指令间的交互
以下示例：四种能力越来越强的超人
Directive&Directive.js
var myModule = angular.module("MyModule", []);
myModule.directive("superman", function() {
return {
scope: {},
restrict: 'AE',
controller: function($scope) {
$scope.abilities = [];
this.addStrength = function() {
$scope.abilities.push("strength");
};
this.addSpeed = function() {
$scope.abilities.push("speed");
};
this.addLight = function() {
$scope.abilities.push("light");
};
this.addFart = function() {
$scope.abilities.push("fart");
};
},
link: function(scope, element, attrs) {
element.addClass('btn btn-primary');
element.bind("mouseenter", function() {
console.log(scope.abilities);
});
}
}
});
myModule.directive("strength", function() {
return {
require: '^superman',
link: function(scope, element, attrs, supermanCtrl) {
supermanCtrl.addStrength();
}
}
});
myModule.directive("speed", function() {
return {
require: '^superman',
link: function(scope, element, attrs, supermanCtrl) {
supermanCtrl.addSpeed();
}
}
});
myModule.directive("light", function() {
return {
require: '^superman',
link: function(scope, element, attrs, supermanCtrl) {
supermanCtrl.addLight();
}
}
});
myModule.directive('fart', function(){
return {
require: '^superman',
link: function(scope, element, attrs, supermanCtrl) {
supermanCtrl.addFart();
}
};
});Directive&Directive.html
controller：中写你想要暴露给外部的方法
link：绑定事件、数据
