內容簡介（smalltext）加輸入字數統計
方法1、統計輸入字符數
smalltext添加一個js來提示及統計已輸入的字數
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、統計輸入字符數并限制數量
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。 |
