Guide to using $attrs method in angularJS_AngularJS

Here is an example of using the $attrs method in angularJS:

Copy code The code is as follows: 无标题文档 http://localhost:81/js/jquery.js "> http://localhost:81/js/angular.min.js "> a_directive 原始内容 原始内容 原始内容 修改 这里 var app = angular.module('Demo', [], angular.noop); app.controller("TestCtrl", function($scope) { $scope.name = "qihao"; }); app.directive("t", function() { return { controller : function($scope){$scope.name = "qq"}, template : " test:implementToParent{{name}} ", replace : true, scope : true //作用域是继承的,默认就是继承的 } }); app.directive("t2", function() { return { controller : function($scope){$scope.name = "nono"}, template : " test:implementToParent{{name}} ", replace : true, restrict : "AE" } }); app.directive("t3", function() { return { template : " test:implementToParent_titleIs:{{title}} title2Is:{{title2}} ", replace : true, restrict : "AE", scope : { title : "@t3", title2 : "@title2" } } }); app.directive('a', function() { var func = function() { console.log('compile'); return function() { console.log('link'); } } var controller = function($scope, $element, $attrs, $transclude) { //$transclude ：是指令标签的复制体 console.log('controller'); console.log($scope); console.log($transclude); //$transclude接受两个参数，你可以对这个克隆的元素进行操作， var node = $transclude(function(clone_element, scope) { $element.append(clone_element); $element.append(" spanTag___ "); console.log(clone_element); console.log('--'); console.log(scope); }); console.log(node); } return { compile: func, template: " ", controller: controller, transclude: true, restrict: 'AE' } }); app.directive('compile',function() { var func = function() { console.log('a compile'); return { pre: function() { console.log('a link pre') }, post: function() { console.log('a link post') }, } } return { restrict : "AE", compile : func } }) app.directive('test', function(){ var func = function($element, $attrs){ console.log($attrs); $attrs.$observe('a', function(new_v){ console.log(new_v); }); } return {compile: func, restrict: 'E'} }); app.controller('TestCtrl', function($scope){ $scope.a = 123; }); app.directive('te', function(){ var func = function($scope,$element, $attrs,$ctrl){ console.log($ctrl) //$attrs.$set. 给这个属性设置b，值为ooo，就是这样 $attrs.$set('b', 'ooo'); $attrs.$set('a-b', '11'); //This is a bit unclear //The second parameter value $attrs.$set('c-d', '11', true, 'c_d'); console.log($attrs); } return { compile: function(){ Return func }, restrict: 'E' } }); app.controller('TestCtrl', function($scope){ $scope.show = function(v){console.log(v);} });
