答
可以使用html的 maxlength 属性来限制字符.就像<textarea cols="5" rows="5" class="elastic" style="overflow: hidden; height: 150px;" maxlength="500"></textarea>
to limit the character you can just use maxlength attribute of html. like <textarea cols="5" rows="5" class="elastic" style="overflow: hidden; height: 150px;" maxlength="500"></textarea>
无论如何它都无法在ie9中工作,但是您可以遵循以下代码.
anyhow it is not going to work in ie9 but you can follow the below code.
<form name="myform">
<textarea name="limitedtextarea" onKeyDown="limitText(this.form.limitedtextarea,this.form.countdown,100);" onKeyUp="limitText(this.form.limitedtextarea,this.form.countdown,100);">
</textarea><br>
<font size="1">(Maximum characters: 100)<br>
You have <input readonly type="text" name="countdown" size="3" value="100"> characters left.</font>
</form>
