第二轮loop,由于上一轮压入到宏认为队列中的两个宏任务都在等待执行:children2所属任务和children5所属任务,会依次按照入队列顺序进行执行,JS引擎线程会先从事件处理线程中的宏任务队列取出children2所属宏任务压入到任务执行栈,然后开始执行,输出children2,并将children3压入到微任务队列。 第二轮loop,执行完children2
宏任务①中的代码执行完成后,会查找微任务队列,于是输出children3;然后开始执行宏任务②,即第二个 setTimeout,输出children5,此时将.then放到微任务队列中。 宏任务②中的代码执行完成后,会查找微任务队列,于是输出children7,遇到 setTimeout,放到宏任务队列中。此时微任务执行完成,开始执行宏任务,输出children6; 最后...
通过swiper 强大的 api 文档,解决了上述出现的几个问题。关键点在于:当loop设置为 true 的时候,不能再用activeIndex或者clickedIndex。只能用realIndex。官方的解释为:当前活动块的索引,与activeIndex不同的是,在loop模式下不会将复制的块的数量计算在内。 点击事件不能绑定在dom上 不过稍不注意,也会出现新的坑(...

Using the replaceChildren() method. By iterating the DOM nodes and using the removeChild Method In this method, we will iterate the DOM using the while loop or for loop. At every iteration, we will check if there is an element remaining in the node using the nodeObject.hasChildNodes() ...
