/**@desc: 将一个字符串重复自身N次*///版本1:利用空数组的join方法functionrepeat(target, n) {return(newArray(n + 1)).join(target); }//版本2:之所以要创建一个带length属性的对象 是因为要调用数据的原型方法,需要指定call的第一个参数为类数组对象//类数组对象的必要条件是其length属性的值为非负数...
作者:前端小 https://segmentfault.com/a/1190000020204425 本文主要介绍一些最常用的JS字符串函数。 1. charAt(x) charAt(x)返回字符串中x位置的字符,下标从 0 开始。 代码语言:javascript 复制 //charAt(x) var myString = 'jQuery FTW!!!'; console.log(myString.charAt(7)); //output: F 2. charCo...
1. anchor 创建 a 标签字符串 anchor(name),name:a 标签的 name 属性 返回一个 a 标签字符串 let str = "yqcoder";// 不传值str.anchor(); // '<a name="undefined">yqcoder</a>'// 创建 name 属性为 web 的 a 标签字符串str.anchor("web"); // '<a name="web">yqcoder</a>' 2. a...
functionrepeatString(str,n){//一个长度为n+1的空数组用string去拼接成字符串,就成了n个string的重复returnnewArray(n+1).join(str);}console.log(repeatString("abc",3));// abcabcabcconsole.log(repeatString("Hi",5));// HiHiHiHiHi
因此,當你在呼叫 str.repeat 的時候,其實就是在呼叫 String.prototype.repeat,而這就是原型鏈的原理跟運作方式。除了字串以外,其他東西也是一樣的,例如說物件:var obj = {} console.log(obj.a) // undefined console.log(obj.toString) // ƒ toString() { [native code] }明明obj 就是一個空物件,為...
