<! DOCTYPE HTML PUBLIC "-//w3c//dtd HTML 4.01 transitional//en"
"Http://www.w3.org/TR/html4/loose.dtd" >
<meta http-equiv= "Content-type" content= "text/html; charset=gb2312 ">

var charNum = 0;
function Changeinfo ()
{
CharNum = Document.all.ipt.value.length;
var maxLength = document.all.ipt.maxLength;
if (maxlength>=charnum) document.all.info.innerhtml= "Send up to 20 words, remaining" + (20-charnum) + "word. ";
}
-->
</script>

<body>
<input type= "text" id= "IPT" onkeyup= "Changeinfo ()" Maxlength= "><span id=" info "> send up to 20 words </span>

<script language= "JavaScript"
MaxLen = 100;
function Checkmaxinput (form) { 
if (Form.message.value.length > MaxLen) {
Form.message.value = Form.message.value.substring (0, MaxLen);
} else {
Form.remLen.value = maxlen-form.message.value.length;
}
