Practical Usage of a Confirmation Box

// By providing a list and an item, we can confirm before deletion
function removeListItem (list, item)
{

    // Only continue processing if they confirm
    if (confirm("Are you sure you wish to permanently remove this list item?"))
    {
        list.removeChild(item);

    }
}

// Assume "el" is the list item in question
el.onclick = function ()
{

    removeListItem(document.getElementById('my-list'), this);
};
