JS中默认中文字符长度和其它字符长度计算方法是一样的,但某些情况下我们需要获取中文字符串的实际长度,代码如下: function strLength(str) { var realLength = 0, len = str.length, charCode = -1; for (var i = 0; i < len; i++) { charCode = str.charCodeAt(i); if (charCode >= 0 && charCode <= 128) { r
方法一: var jmz = {}; jmz.GetLength = function(str) { ///<summary>获得字符串实际长度,中文2,英文1</summary> ///<param name="str">要获得长度的字符串</param> var realLength = 0, len = str.length, charCode = -1; for (var i = 0; i < len; i++) { cha
