Get attribute value from input text
<p>I want to get attribute value of each input field.</p>

<pre><code>&lt;input type="text" id="qty" data-id="{{$item-&gt;rowid}}" value="{{$item-&gt;qty}}"&gt;

function goUpdateCart(){

    $('input[type=text]').each(function(){

        alert($('input[type=text]').getAttribute("data-id"));
    })
}
</code></pre>

<p>My function can't work correctly</p>
