判断输入框里是否含用汉字且计算它的字节数(一个汉字两个字节)
<input type=text name=txt>
<input type=button value=ok onclick="cc()">
<script language=javascript>
function cc()
{
var j = 0;
var s = document.all.txt.value;
if (s=="")return;
if (/[^/x00-/xff]/g.test(s)) alert("含有汉字");
else alert("全是字符");
for (var i=0; i<s.length; i++)
{
if (s.charCodeAt(i) > 255) j = j + 2;
else j++
}
alert("字符数："+j);
}
