jQuery popup the easy way

Here is a fast and easy way to create jQuery popup.

// --- code popup ---
function openPopup() {
    $(this).clone(false).appendTo($("#_code"));
    $("#_code").show();
}

function closePopup() {
    $("#_code").html("");
    $("#_code").hide();
}

function initCode() {
    $(".code").click(openPopup);
    $(".code").css({cursor: "pointer"});
    $('body').append('<div id="_code"></div>');
    $('#_code').css( { 'text-align': "justify", position: "fixed", 
                        left:0, top:0, width: "100%", height: "100%", 
                        "background-color": "rgba(0, 0, 0, 0.8)", 'z-index':2000, 'padding':'3px'} );
    $('#_code').hide();
    $('#_code').click(closePopup);
}
// --- end of code popup section ---

What does this code do?

At the loading of the page, I create a div as wide as the window. This div is a bit transparent. Then I hide it. I also take care to its z-index value to be sure it is behind all elements.

Then when we click on a div of class code, I copy the content into this new wide div, and I show it. Really simple but really efficient. No need to use a jQuery plugin.
