Hey guys being following jQuery basics and I'm just wondering how jQuery knows how to put the captions in-between the <p> tags?
Here is the code:
var $overlay = $('<div id="overlay"></div');
var $image = $("<img>");
var $caption = $("<p></p>");
$overlay.append($image);
$overlay.append($caption);
$("body").append($overlay);
$("#imageGallery a").click(function(event){
event.preventDefault();
var href = $(this).attr("href");
$image.attr("src", href);
$overlay.show();
var captionText = $(this).children("img").attr("alt");
$caption.text(captionText);
});
$overlay.click(function(){
$overlay.hide()
});
I'm just very curious to how it does this?

11,239 Points$caption, at that point, is just a DOM element like anything else you would have in your HTML. If your HTML looked like this:
<body>
<div></div>
</body>
you could use jQuery to add text to you div like so:
$('div').text("new text here");
you are doing the same thing in your example, the only difference is you aren't adding the caption <p> directly into the HTML file, instead you are inserting it into the DOM with jQuery and then modifying the text.

47,842 PointsI often wonder the same thing myself, but I just wanted to warn you of a little syntax error near the top. You forgot to add the
>
to the closing</div>
tag stored invar $overlay
. It should look like this:var $overlay = $('<div id="overlay"></div>');
