Stationary corner triangle DIV using CSS

Ever wanted a triangle DIV that hovers over the page and has a drop shadow? Here's one I built using nothing but CSS 3 and HTML5:
To modify the triangle, edit the border-width and border-color on the div#corner-triangle. Read more details on my Stack Overflow answer. You can also use the nifty CSS Triangle Generator.

Dynamically replace HTML5 video with Flash in Fancybox

For my current project, I needed to dynamically (based on whether the device supported HTML5 or not) replace HTML5 video tags with a Flash player. What made this more challenging was that the video player needed to be in a Fancybox.

A day's worth of coding resulted in the following JavaScript function. It's heavily commented so it should be self-explanatory. Drop me a comment if something doesn't make sense. You need to include the latest jQuery library for this to work.

function flashPopup(){
   // Declare some variables.
   var el = "";
   var vidFileName = "";
   var posterPath = "";
   var placeHolderPosterPath = "";
   var replacement = "";
   var imgTitle = "";
   var videoTag = "";
   var boxId = "";
   var flashId = "";
   var dotPosition = "";
   var swf = ""
  
   // Loop over each video tag.
   $("video").each(function(){
     // Reset the variables to empty.
     el = "";
     vidFileName = "";
     posterPath = "";
     imgTitle = "";
     placeHolderPosterPath = "";
     replacement = "";
     videoTag = "";
     flashId = "";
     swf = "";
    
     // Get a reference to the current object.
     el = $(this);
    
     // Set some values we'll use shortly.
     boxId = this.id + "_flashBox";
     flashId = this.id + "_flashPlayer";
    
     /*
       Set the ID attribute of the first DIV in this element's parent's
       parent. This "box" will have the Fancybox attached to it.
     */
     el.parent().parent().find("div:first").attr("id",boxId);

    
     /*
       Fetch the MP4/M4V video from the <source> tags. Need to go to the
       parent of the current tag to find them.
     */
     el.parent().find("source").each(function(){
       if ($(this).attr("src").indexOf("m4v") != -1 ||
         $(this).attr("src").indexOf("mp4") != -1){
         vidFileName = $(this).attr("src").substring($(this).attr("src").lastIndexOf("/")+1);
       }
     });
    
     /*
       IE (< 9) and older browsers use the Flash player, which overlays a 'Play' button
       on the poster image by default; so we use a poster image that doesn't have
       a play button. Otherwise we'd end up with a play button on top of a play
       button.
      
       We have an img tag inside the <video> tag which we'll use (by adding "-ie" to the
       filename) for the Flash player's image attribute. The next two lines find the file
       and its path.
     */
     dotPosition = el.parent().find("img").attr("src").lastIndexOf(".");
     posterPath = el.parent().find("img").attr("src").substring(0,dotPosition) + "-ie" + el.parent().find("img").attr("src").substring(dotPosition);
    
     /*
       Use the same image but this time don't add "-ie" to its name. This will be for the
       main placeholder linked image; when the user clicks it, the Fancybox pops up with
       the Flash player.
     */
     placeHolderPosterPath = el.parent().find("img").attr("src");
    
     /*
       Fetch the image's title attribute, which we'll use for the linked image's title.
       This will appear as the title on the Fancybox.
     */
     imgTitle = el.parent().find("img").attr("title");
    
     /*
       Concatenate the linked image that will take the place of the <video> tag.
     */
     replacement = "<a title='" + imgTitle + "' id='" + boxId + "' href='javascript:;'><img src='" +
       placeHolderPosterPath + "' style='float:left; padding-left:5px; '/></a>"
  
     // Replace the parent of the current element with the linked image HTML.
     el.parent().replaceWith(replacement);

     /*
       The swfobject library can't be used with Fancybox (as far as I know). but
       we can pass a Flash player of our own design into the Fancybox as its content.
       Here, we concatenate the Flash player and point to the swfobject player.swf
       file. We'll still use that player, but build our own OBJECT and EMBED tags.

     swf = "<object id='" + flashId + "' classid='clsid:D27CDB6E-AE6D-11cf-96B8-444553540000' width='372' height='209'>" +

     usually requires some trial-and-error).

     closes it, respectively.

   });
}

Update: A few requests have come in for a version of the code to allow HTML5 videos on a page to be placed into a Fancybox. Here's the demo, with a very special thanks to Pipsqueak.

Here's the HTML code, with the JavaScript followed a little further down:

<!doctype html>
<html lang="en"> 
<head>
    <meta charset="utf-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1">

    <!-- 
        In addition to the stylesheet for the Fancybox
        component, the following styles control the 
        look of the page and the linked image.
    -->
    <style type="text/css">
        body {

     }
 
        #main {

         padding:5px
     }
    </style>
    <!--

Escape the App Store: 4 ways to create smartphone Web apps

A very nice article on the merits and drawbacks of building HTML apps for handhelds. An excerpt:

It doesn't matter why you want to develop mobile apps. The problem is that following through is still pretty tricky. The iPhone and iPad want code written in Objective-C, and that language remains a bit obscure. Plus, once you're done coding, there's a distinct possibility that Apple will slam the door to the App Store right in your face for some unknowable reason.

Getting JW HTML5 Player to work on IE, Part II

In part 1, we talked about getting the player working on IE with the beta version of the JW HTML5 Player. Now that version 1.0 of the JW Player is out, let's revisit the issue of getting it working on various browsers, including IE.

First off, the full release has a different syntax for initialization of the player. This code demonstrates how to set up the player for all video tags on the page as well as for IE. Don't forget to include the jwplayer.js file on the page.

$(document).ready(function(){

$("video").each(function(){
  if (jQuery.browser.msie){
    var vidFile = "";
    $(this).parent().find("source").each(function(){
      if (jQuery(this).attr("src").indexOf("m4v") != -1 ||
        jQuery(this).attr("src").indexOf("mp4") != -1){
        vidFile = jQuery(this).attr("src"); //.substring(jQuery(this).attr("src").lastIndexOf("/")+1);
        //alert("vidFile: " +vidFile);
      }
      $(this).remove();
    });
    $("[id="+$(this).attr("id")+"]").attr("src",vidFile);
  }

  jwplayer($(this).attr("id")).setup({
    events: {
        onPlay: function() {videoEventHandler(1)},
        onComplete:  function() {videoEventHandler(0)}
    },
    //debug: "console",
    players:
       [
         { type: "html5" },
         { type: "flash", src: "global/vid/player.swf" }
       ],
    components: {
      controlbar: {
        position: 'bottom'
      }
    }
  });
});


});

function videoEventHandler(type){
switch(type){
  case 1:
    stopSlider();
    break;
  case 0:
    startSlider();
    break;
  default:
    return;
}
}

You should try the above code without the if (jQuery.browser.msie){...} to see if it works for you on IE; it didn't for me so I've thrown that in. The code pulls the MP4/M4V video source and applies it to the main video tag as a src attribute. This took quite a bit of trial-and-error to discover.

Note that in the version I was using, there was a bug in Firefox: FF doesn't like the console object being called when without the Firebug window being open. IE has the console object available by default. So if you set debug: "console", you might get errors on Firefox.

In addition, when creating your video tags, ensure that the MP4 source tag comes before OGV: Chrome chokes if you have OGV first, perhaps because it can play both video types via its HTML5 implementation. Also note the event handlers attached to the video player; these are called for the AnythingSlider to stop and start.
