<p>to limit the character you can just use <strong>maxlength</strong> attribute of html. like <code>&lt;textarea cols="5" rows="5" class="elastic" style="overflow: hidden; height: 150px;" maxlength="500"&gt;&lt;/textarea&gt;</code></p>

<p>anyhow it is not going to work in ie9 but you can follow the below code.</p>

<pre><code>&lt;form name="myform"&gt;
&lt;textarea name="limitedtextarea" onKeyDown="limitText(this.form.limitedtextarea,this.form.countdown,100);" onKeyUp="limitText(this.form.limitedtextarea,this.form.countdown,100);"&gt;
&lt;/textarea&gt;&lt;br&gt;
&lt;font size="1"&gt;(Maximum characters: 100)&lt;br&gt;
You have &lt;input readonly type="text" name="countdown" size="3" value="100"&gt; characters left.&lt;/font&gt;
&lt;/form&gt;
</code></pre>

blocks|key|3265409|text|请记住，用户也可以过去文字。使用keypress是错误的，您必须使用keyup事件，如下所示：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3265410|++++$('#my-textarea').keyup(function(event){

++++++++++++++++return+false;
++++++++++++}
++++++++}
++++++++$left.text(300+-+len);
++++});|code-block|syntax|javascript|3265411|这将id为"my-+textarea“的textarea限制为300个字符，并显示id为"my-textarea-length-+left”的span或div中的剩余数量。|3265412|它可以正确地处理文本粘贴。|3265413|HTML标记：|3265414|<textarea+rows="4"+id="my-textarea"></textarea>
<span+id="my-textarea-length-left"></span>|3265415|entityMap^0|0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|Q|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|R|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|S|8|@]|9|@]|A|$]]|$1|I|3|J|5|6|7|T|8|@]|9|@]|A|$]]|$1|K|3|L|5|6|7|U|8|@]|9|@]|A|$]]|$1|M|3|N|5|D|7|V|8|@]|9|@]|A|$E|F]]|$1|O|3|-4|5|6|7|W|8|@]|9|@]|A|$]]]|P|$]]

<p>Please keep in mind that the user can also past text. Using keypress is wrong, you will have to use the keyup event like so:</p>

<pre><code>    $('#my-textarea').keyup(function(event){
        var $field = $('#my-textarea');
        var $left = $('#my-textarea-length-left');
        var len = $field.val().length;
        if (len &gt;= 300) {
            $field.val( $field.val().substring(0, 299) );
            $left.text(0);
            if (event.which != 8) {
                return false;
            }
        }
        $left.text(300 - len);
    });
</code></pre>

<p>This limits the textarea with id "my-textarea" to 300 characters and shows the amount left in a span or div with the id "my-textarea-length-left".</p>

<p>It properly handles text paste.</p>

<p>HTML Markup:</p>

<pre><code>&lt;textarea rows="4" id="my-textarea"&gt;&lt;/textarea&gt;
&lt;span id="my-textarea-length-left"&gt;&lt;/span&gt;
</code></pre>


<p>I want to Limit the characters in a textare in jquery .here is my jquery code</p>

<pre><code>$('#editnote-tooltip-wrapper').appendTo($(this).closest('.editnote-tip-wrapper')).fadeIn(300).css({ 'position': 'absolute', 'left': 0, 'top': 0, 'z-index': '10000' }).find('.content').html('&lt;textarea cols="5" rows="5" class="elastic" style="overflow: hidden; height: 150px;"&gt;&lt;/textarea&gt;' + $html);
</code></pre>

<p>how can I make this possible.anyone help?</p>
