How to call function inside itself
<p>I have a function that I want to call again inside, after the last line finishes.</p>

<p>Maybe it will be more understandable if I show code.</p>

<pre><code>function updateQuantity(){ 
    // further code where I change same data
    // and now I want to start function again but with remembering the input element that called it previously 
    updateQuantity(this);  // I tried it this way but it doesn't work
}
</code></pre>

<p>Any idea?</p>
