jQuery - moving embedded video to top?

The code below will find an image if it exists and move it above the title and text. So, if the markup looks like this:

<h2>Some fancy title</h2>
<p>Some interesting text</p>
<img src="someimage.jpg" />

or even this:

<p><h2>Some fancy title</h2></p>
<img src="someimage.jpg" />
<p>Some interesting text</p>

It will reposition elements so that it looks like this:

<img src="someimage.jpg" />
<h2>Some fancy title</h2>
<p>Some interesting text 

Now, I'm trying to figure out how to rework the code so that if there's a video in the content (whether or not the post also has images), it will move the video above everything else. Can someone suggest or show me a way to do that?

This is the current code, as I have it right now:

$j('#hp-featured-item > div[id^="post-"]').each(function() {
  if($j(this).find('embed')) {
  var id=this.i开发者_如何学God.match(/^post-([0-9]+)$/);
  var imgt = $j("img:eq(0)");
  var pt = $j("p:not(:has(img)):eq(0)");
  var hh = $j("h2:eq(0)");
  $j(this).html('');
  $j(this).append(imgt).append(hh).append(pt);
  $j(this).each(function() {
   var img = $j('img');
   $j(img).wrap($j('<a>').attr('href', '/blog/?p='+id[1]));
   var h2 = $j('h2');
   $j(h2).wrap($j('<a>').attr('href', '/blog/?p='+id[1]));
  });
  } else {
   var id=this.id.match(/^post-([0-9]+)$/);
   var imgt = $j("embed:eq(0)");
   var pt = $j("p:not(:has(embed)):eq(0)");
   var hh = $j("h2:eq(0)");
   $j(this).html('');
   $j(this).append(imgt).append(hh).append(pt);
   $j(this).each(function() {
    var img = $j('embed');
    $j(img).wrap($j('<a>').attr('href', '/blog/?p='+id[1]));
    var h2 = $j('h2');
    $j(h2).wrap($j('<a>').attr('href', '/blog/?p='+id[1]));
   });
  }
 });


What you want to do is pretty straight forward with jQuery. I put together a test page and a suggested solution. Be sure to look at the source of the test page to see the original HTML content before it was rearranged.

You can view the test page here: http://pixelgraphics.s3.amazonaws.com/stackoverflow/1744585/index.html

Here is the rework of your jQuery code:

$j('#hp-featured-item > div[id^="post-"]').each(function() {
    var $div = $j(this),
        $h2  = $div.find('h2:first'),
        $obj = $div.find('object, embed, img').filter(':first'),
        id   = this.id.match(/^post-([0-9]+)$/);

    if( $obj.size() > 0){
        // Find parent
        var $par = $obj.closest('p');

        // Move to top of div
        $obj.prependTo($div);

        // Remove the now empty parent
        $par.remove();

        if( $obj.is('img')){
            // You can't wrap objects and embeds with links, so make sure we just wrap images
            $obj.wrap( $j('<a></a>').attr('href', '/blog/?p='+id[1]));
        }
    }

    // Wrap the contents of the h2, not the h2 itself, with a link
    $h2.wrapInner( $j('<a></a>').attr('href', '/blog/?p='+id[1]) );

}); 

The only thing this doesn't do that your original code seemed to do was to remove all other content except the first img/embed, h2, and paragraph. This leaves the rest of the content in place. If you wanted to do that, then just add this line before the closing });:

$div.children('p:gt(0)').remove();
0
