下面示例为 String 类型扩展一个原型方法,用来把字符串转换为数组。在函数中使用 charAt() 方法读取字符串中每个字符,然后装入一个数组并返回。 1. String.prototype.toArray = function () { //把字符串转换为数组 2. var 1 = this.length; a = []; //获取当前字符串长度,并定义空数组 3. if (1) ...
Ruby是一种动态、面向对象的编程语言,它提供了丰富的内置函数和库,使得开发者可以轻松地进行各种编程任务。在Ruby中,字符串(String)和数组(Array)是常见的数据类型。 将字符串转换为数...
console.log(a.toLowerCase()) // "hello" 字符串 查: 1、charAt(index)返回索引位置的字符 let message = "abcde" console.log(message.charAt(2)) // "c 2、indexOf(char)从字符串开头去搜索传入的字符串,并返回位置(没有返回-1) let char = "hello world" console.log(char.indexOf("o")) /...
这种方式比较简单,推荐使用 字符串转数组,反转数组,数组转字符串。 split(""):根据空字符串拆分数组 reverse():数组反转元素位置 join(""):数组转回字符串,且不带分隔符 实现效果如图: 方式2: 这种方式相对麻烦,但也可以。 定义新的空字符串,遍历str,charAt()是取字符串的一个字符,先去最后一个字符,再取倒...
一、字符串转byte数组 functionstringToByte(str){varbytes=newArray(10000);var len, c;len = str.length;for(var i =0; i < len; i++) {c = str.charCodeAt(i);if(c >=0x010000&&c <=0x10FFFF) {bytes.push(((c >>18) &0x07)| 0xF0);bytes.push(((c >> 12) & 0x3F) | 0x80...

If case insensitivity is required, remove either upper or lower case characters from chars string and it will generate 35^3 (42,875) unique values. Can be easily adapted so that first char is always a letter, or all letters. No dobut it can be optimised, and could also refuse to ...
