How do I clear the content of a div using JavaScript? [closed]

When the user clicks a button on my page, the content of a div should be cleared. How would I go about accomplishing this?

Just Javascript (as requested)

Add this function somewhere on your page (preferably in the <head>)

function clearBox(elementID)
{
    document.getElementById(elementID).innerHTML = "";
}

Then add the button on click event:

<button onclick="clearBox('cart_item')" />

In JQuery (for reference)

If you prefer JQuery you could do:

$("#cart_item").html("");

You can do it the DOM way as well:

var div = document.getElementById('cart_item');
while(div.firstChild){
    div.removeChild(div.firstChild);
}
