《理解 ES6》阅读整理：函数（Functions）（三）Function Constructor & Spread Operator

增强的Function构造函数(Increased Capabilities of the Function Constructor) 在Javascript中Function构造函数可以让你创建一个新函数,不过这个功能并不经常使用.Function构造函数接收函数参数和函数体作为参数,参数都必须是字符串.下面是一个例子: var add = new Function("first", "second", "return first+second"…

spread表格树实现

先上图看下效果图: 玩表格的朋友应该对Component和C1Flexgrid并不陌生吧.其实我也有用C1和DGV扩展了一个表格树,占有内存小,效率也可以,但是UI是硬伤,中规中矩,不美观.我上面是基于spread扩展实现的,站在可扩展的角度,C1不错,spread我可以说完全没有扩展性可言么?小日本写的代码感觉很不规范(反编译看的). 实现思路: 首列是重写BaseCellType基类,重绘了UI,主要是线.自定义图标.节点层级的绘制,主要是用rang确定绘制坐标,整个树层级的维护是基于链表实…

spread语法解析与使用

@[spread, javavscript, es6, react] Spread语法是ES6中的一个新特性,在需要使用多参数(函数参数).多元素(数组迭代)或者多变量(解构赋值)的地方使用spread语法,可以让表达式的结果平铺化 java中的可变参数熟悉java的朋友对可变参数应该比较熟悉了,他用来指定方法接受不定个数的参数,参数被传进来后形成一个数组,可供你迭代使用分别取出传进来的参数. public int sum(int... input){ int result; for(int…
