最q和JavaScriptU缠上了?/p>
遇到q么一个问题，数据库的字符集ؓUTF-8的，要在面上用JavaScript验证输入的文本用UTF-8存储时占用字节长度。JavaScript的String对象有length属性，但是q个计算的是字符敎ͼ不是字节敎ͼ问题LL覆去的，记得当年玩Delphi的时候，q得写程序计字W串的字W数Q因为Delphi中String的length是字节数...Q。偷懒一点的办法是将验证代码中最大长度设|ؓ数据库中对应字段的长度的1/3Q但是这样准来说有点不合适?/p>
所以想办法在JavaScript中判断在UTF-8下存储的String的字节数Q在|上扑ֈ很多关于Unicode介绍的文，最重要的是字符~码数值对应的存储长度Q?/p>
UCS-2~码(16q制) UTF-8 字节?二进?
0000 - 007F 0xxxxxxx Q?字节Q?br />
0080 - 07FF 110xxxxx 10xxxxxx Q?字节Q?br />
0800 - FFFF 1110xxxx 10xxxxxx 10xxxxxx Q?字节Q?
于是代码如下Q?/p>
function mbStringLength(s) {
var totalLength = 0; var i; var charCode; for (i = 0; i < s.length; i++) {
charCode = s.charCodeAt(i); if (charCode < 0x007f) { totalLength = totalLength + 1; } else if ((0x0080 <= charCode) && (charCode <= 0x07ff)) { totalLength += 2; } else if ((0x0800 <= charCode) && (charCode <= 0xffff)) { totalLength += 3; } } //alert(totalLength); return totalLength; }
实际?0x0080?x07ff之间的字W很会在实际用戯入中用到?/p>
