JavaScript是一种面向对象的动态语言,它包含类型、运算符、标准内置(built-in)对象和方法。它的语法来源于Java和C,所以这两种语言的许多语法特性同样适用于JavaScript。需要注意的一个主要区别是JavaScript不支持类,类这一概念在JavaScript通过对象原型(object prototype)得到延续(有关ES6类的内容参考这里Classe
栈(Stack)栈是一种常见的数据结构,栈只允许在结构的一端操作数据,所有数据都遵循后进先出(Last-In First-Out,LIFO)的原则。 现实生活中最贴切的的例子就是羽毛球桶,通常我们只通过球桶的一侧来进行存取,最先放进去的羽毛球只能最后被取出,而最后放进去的则会最先被取出。 栈内存之所以叫做栈内存,是因为栈内存...

These classes can be found in component-animations.less. Via data attributes Just add data-toggle="collapse" and a data-target to the element to automatically assign control of a collapsible element. The data-target attribute accepts a CSS selector to apply the collapse to. Be sure to add ...
Dynamic data layers provide the ability to create layers on the fly from data referenced in registered workspaces. The data may be tables with or without geometries, feature classes, and rasters. These data sources are not directly visible to the services directory, but may be published and con...
Most class systems for JS let you define classes by passing an object. P.js lets you pass a function instead, which allows you to closure private methods and macros. It's also <0.4kb minified (make report: 467). Unlikesomeotherframeworksoutthere, Pjs doesn't do any of this: ...
ActionScript 3.0 includes capabilities related to classes that are not found in JavaScript 1.7. Runtime classes The runtime includes built-in classes, many of which are also included in standard JavaScript, such as the Array, Date, Math, and String classes (and others). However, the runtime ...
