//获取字符串长度String.prototype.strLen = function() { var len = 0; for (var i = 0; i < this.length; i++) { if (this.charCodeAt(i) ) len += 2; else len ++; } return len; } //将字符串拆成字符,并存到数组中 String.prototype.strToChars = function(){ var chars = new Array();
目的:计算字符串长度(英文占1个字符,中文汉字占2个字符) 方法一: 代码如下: String.prototype.gblen = function() { var len = 0; for (var i=0; i<this.length; i++) { if (this.charCodeAt(i)>127 || this.charCodeAt(i)==94) { len += 2; } else { len ++;
/*** 计算字符串长度* 参数是要计算的字符串* 返回值当前字符串的长度*/function charactersLen (words) { let tempMapWordNum = {} let doubleByteTotal = 0 // 双字节 let chineseTotal = 0 // 汉字 let singleByteTotal = 0 // 单字节 let numTotal = 0 for (let i = 0; i < words.length; i++) { let c =
首先看看判断字符串长度的几种方法(英文占1个字符,中文汉字占2个字符) 方法一: function strlen(str) { var len = 0; for (var i = 0; i < str.length; i++) { var c = str.charCodeAt(i); //单字节加1 if ((c >= 0x0001 && c <= 0x007e) || (0xff60 <= c && c <= 0xff9f)) { len++
