内容简介（smalltext）加输入字数统计
方法1、统计输入字符数
smalltext添加一个js来提示及统计已输入的字数
把以下smalltext字段的输入的html表单
<textarea name="smalltext" cols="80" rows="10" id="smalltext"><?=$ecmsfirstpost==1?"":ehtmlspecialchars(stripSlashes($r[smalltext]))?></textarea>
替换为
<script language="javascript">
function countChar(textareaNamezzjs,spanName){
document.getElementById(spanName).innerHTML=document.getElementById(textareaNamezzjs).value.length;
}
</script>
已经输入<span id="counter" style="color:#ff0000">0</span>字<br>
<textarea id="smalltext" name="smalltext" cols="80" rows="10" onkeydown="countChar('smalltext','counter');" onkeyup="countChar('smalltext','counter');"><?=$ecmsfirstpost==1?"":ehtmlspecialchars(stripSlashes($r[smalltext]))?></textarea>

方法2、统计输入字符数并限制数量
把以下smalltext字段的输入的html表单
<textarea name="smalltext" cols="80" rows="10" id="smalltext"><?=$ecmsfirstpost==1?"":ehtmlspecialchars(stripSlashes($r[smalltext]))?></textarea>
替换为
<SCRIPT LANGUAGE="JavaScript">
<!--//
function textCounter(field, countfield, maxlimit)
{
if (field.value.length > maxlimit)
field.value = field.value.substring(0, maxlimit);
else
countfield.value = maxlimit - field.value.length;
}
//-->
</SCRIPT>
<textarea name="smalltext" cols="80" rows="10" id="smalltext" onMouseOver="textCounter(this.form.smalltext,this.form.remLen,160);"
onKeyUp="textCounter(this.form.smalltext,this.form.remLen,160);"><?=$ecmsfirstpost==1?"":ehtmlspecialchars(stripSlashes($r[smalltext]))?></textarea> <FONT color=#999999>还能输入<input readonly style="TEXT-ALIGN:center;height:18px;" type=text name=remLen size=2 maxlength=2 value="160">字。
