jquery issue with chekbox : <p>This is my html checkbox --</p>

<pre><code>&lt;input type="checkbox" id="export_1_field_title" value="title"&gt;
</code></pre>

<p>in jquery, i want to check whether checkbox is checked or not, if check then will read the value, so this is my query --</p>

<pre><code>                var title = '';
                if($("#export_1_field_title").is("checked"))
                {
                    title = 'title';
                }
                alert('Here '+title);
</code></pre>
