Jquery在某个索引处插入新行到表中

在事件循环中为nodejs任务分配优先级

有什么办法可以在事件循环中对Node.js任务应用优先级。 我想为nodejs的事件循环中存在的任务分配优先级。 假设在事件循环中有5个作业A,B,C,D,E具有相同的优先级,然后接收下一个作业,其优先级高于后五个作业。 然后事件循环开始执行该更高优先级的作业。 node.js中的事件循环不支持优先级。 查看一些文档: http://nodejs.org/api/events.html http://strongloop.com/strongblog/node-js-event-loop/ 没有重写

why manipulating DOM in controller is a bad thing?

Its common knowledge that DOM manipulations should not be performed in AngularJS Controller, its very hard however to find why exactly is it a bad thing. All the sources say its difficult to test and because controller should be used for communication between directives, but fail to illustrate with code why this is a bad thing. From my understanding I would think that controller, unlike direct

为什么在控制器中操纵DOM是一件坏事?

它的常见知识是DOM操作不应该在AngularJS Controller中执行,但它很难找到为什么它是一件坏事。 所有的消息来源都说它很难测试,因为控制器应该用于指令之间的通信,但是没有用代码说明为什么这是一件坏事。 根据我的理解,我认为控制器与指令不同,不会与任何特定的HTML相关联,因此所有DOM修改控制器将会执行的操作很可能会失败。 这肯定会使开发和测试复杂化。 在指令的控制器在子指令的链接函数之前执行也会失败,因为
