javascript - 如何将文本 "Max Characters"添加到 JavaScript 计数器？

Question

我有一个最多可容纳 125 个字符的 JavaScript 计数器。一旦达到 125，计数器就会显示“125”。我怎样才能让它说“最大字符数”？

<script language="JavaScript">
function textCounter(field, countfield, maxlimit) {
if (field.value.length > maxlimit) 
field.value = field.value.substring(0, maxlimit);
// otherwise, update 'characters left' counter
else 
countfield.value = field.value.length;
}
</script>

<center>
<form name=myform action="#">
<font size="1" face="arial, helvetica, sans-serif"> 
( You may enter up to 125 characters. )<br>
<textarea name=message wrap=physical cols=28 rows=4 
 onKeyDown="textCounter(this.form.message,this.form.remLen,125);" 
 onKeyUp="textCounter(this.form.message,this.form.remLen,125);"
    ></textarea>
<br>
<input readonly type=text name=remLen size=3 maxlength=3 value="0"> characters total</font>
</form>
</center>

function textCounter (field, countfield, maxlimit) {
    if (field.value.length > maxlimit) {
        field.value = field.value.substring(0, maxlimit);
        countfield.value = 'max characters';
    } else { // otherwise, update 'characters left' counter
        countfield.value = field.value.length;
    }
}
