Get value attribute of the clicked checkbox via JQuery
<p>I have got this <code>checkbox</code> which has value <strong>1</strong>.</p>

<pre><code>&lt;input type="checkbox" name="option_1" id="checkbox_1" value="1"&gt;
</code></pre>

<p>Also I use this method to make checked/unchecked it. </p>

<pre><code>$('input[id^="checkbox_"]').not('#checkbox_all').click(function () {
            $('#checkbox_all').prop('checked', false);

    // Get 'VALUE' of the checkbox here   

});
</code></pre>

<p>What I need is somehow get 'VALUE' of the clicked <code>checkbox</code>. So In that case it should be <strong>1</strong>.</p>

<p>Any clue how do it could be done?</p>

<p>Thank you!</p>
