首先,一些设置阶段的代码:varinstances=[];classParent{staticdoImportantStuff(){console.log('Parentdoingimportantstuff');returnfalse;}staticinit(){if(this.doImportantStuff())instances.push(newthis());}}classChild1extendsParent{staticdoImportantStuff(){console.log('Child1doingimportantstuff');if(someCondition)
HTML:text1text2JS:if($(".sonuc").has(":contains('text1')").length){$('.sonuc').parent().addClass('hobi')}它的工作,但添加hobi类所有父div。但我只想添加text1的父div。我该如何解决? 最佳答案 您可以使用:contains选择器和所需的div选择器:$('.views-row:contains(text1)').addClass('hobi');WorkingFiddle
我设置了父subview模型对象结构,需要从子对象更新父对象的可观察对象。我基本上想出了两种模式:1]将父属性的引用传递给子属性并从子属性中更新属性:varParentViewModel=function(){varself=this;this.selectedItem=ko.observable();this.child=ko.observable(newChildViewModel(self.selectedItem));}varChildViewModel=function(parentSelectedItem){varself=this;this.id=ko.observabl
当使用onEnter重定向到一个状态时,如果新状态是当前状态的子状态,则会发生无限循环。示例:$stateProvider.state'inventory',url:'/inventory'templateUrl:'views/inventory.html'controller:'InventoryCtrl'onEnter:()->$state.go'inventory.low'.state'inventory.low',url:'/low'templateUrl:'views/inventory-table.html'controller:'LowInventoryCtrl'时间:$
假设我这样做:sAngular.app.directive('dostuff',['$compile',function($compile){return{restrict:'C',scope:{someVar:'='},link:function(scope,element,attrs){element.click(function(){//dostuffscope.someVar='somethingelse';vardropdownOutput=template();varcompiledOutput=$compile(dropdownOutput)(scope);scope.$
我想在网站上显示所选分类的父级。为此,我有上面的代码,但问题在于它在具有现在结构的列表中显示所有选定的分类法。global$post;$features=get_the_terms($post->ID,'property-feature');if(!empty($features)&&is_array($features)&&!is_wp_error($features)){?>slug,'property-feature').'">'.$single_feature->name.'';}?>例子:父级:选项1,选项2父级2:选项3,选项4如果我选择选项2和选项3我想看父级:选项2父级
早上好,给定以下数据结构(为便于阅读,采用JSON格式)[{"parent":"root","active":"1","label":"Index","route":"/","children":[{"parent":"/","active":"1","label":"Products","route":"/products","children":[{"parent":"/products","active":"0","label":"Test","route":"/test"}]}]},{"parent":"root","active":"1","label":"404","rou
为什么不能在子类中隐藏构造函数?我收到以下异常:Fatalerror:AccessleveltoCIS\Logger\WPLogger::__construct()mustbepublic(asinclassKatzgrau\KLogger\Logger)in/builds/r2o/website/wp-content/mu-plugins/toolsets/lib/cis-logger/src/WPLogger.phponline12父类(superclass)代码(来自外部库):publicfunction__construct($logDirectory,$logLevelThr
我有一个复杂的数组需要排序,它看起来像这样:Array([0]=>Array([id]=>1171409310[parent]=>1171287657[createdAt]=>2013-12-20T12:42:19)[1]=>Array([id]=>1171360372[parent]=>1171313704[createdAt]=>2013-12-20T11:18:46)[2]=>Array([id]=>1171313704[parent]=>1171304353[createdAt]=>2013-12-20T10:14:46)[3]=>Array([id]=>1171304353[
我有一个函数可以从我的数据库中获取父项的所有子项的ID。因此,如果我查找id7,它可能会返回一个包含5、6和10的数组。然后我想做的是递归地找到那些返回的id的child,依此类推,直到child的最终深度。我曾尝试编写一个函数来执行此操作,但我对递归感到困惑。functiongetChildren($parent_id){$tree=Array();$tree_string;if(!empty($parent_id)){//getOneLevel()returnsaone-dimentionalarrayofchildids$tree=$this->getOneLevel($pare
