內(nèi)容簡介（smalltext）加輸入字數(shù)統(tǒng)計 

方法1、統(tǒng)計輸入字符數(shù)

smalltext添加一個js來提示及統(tǒng)計已輸入的字數(shù) 

 把以下smalltext字段的輸入的html表單

<textarea name="smalltext" cols="80" rows="10" id="smalltext"><?=$ecmsfirstpost==1?"":ehtmlspecialchars(stripSlashes($r[smalltext]))?></textarea>

替換為

<script language="javascript">

function countChar(textareaNamezzjs,spanName){

document.getElementById(spanName).innerHTML=document.getElementById(textareaNamezzjs).value.length;

}

</script>

已經(jīng)輸入<span id="counter" "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、統(tǒng)計輸入字符數(shù)并限制數(shù)量

把以下smalltext字段的輸入的html表單

<textarea name="smalltext" cols="80" rows="10" id="smalltext"><?=$ecmsfirstpost==1?"":ehtmlspecialchars(stripSlashes($r[smalltext]))?></textarea>

替換為

<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>還能輸入<input readonly "TEXT-ALIGN:center;height:18px;" type=text name=remLen size=2 maxlength=2 value="160">字。
