Jquery replace string

Question

May sound like a total noob question but i'm looking for a javascript (and or jquery) function to replace an element in this code :

<embed id="ply" width="800" height="400" 
 flashvars="file=http://example.com/play/"
 allowscriptaccess="always" 
 allowfullscreen="true" 
 quality="high" bgcolor="#00000" 
 name="ply" style="" 
 src="/video-player.swf" 
 type="application/x-shockwave-flash"/>

I want to be able to replace the :

flashvars="file=http://example.com/play/"

and append some text (for video seeking) :

flashvars="file=http://example.com/play/234983"

Must be really easy to do, but i'd appreciate help for some more experienced user.

Answer 1

$("#ply").attr("flashvars", $("#ply").attr("flashvars") + "/234983");

Update If you want to reload the player, this may work. It will clone the existing embed tag with the ID ply, only replacing the flashvars attribute value. This effectively removes ply from the DOM and then inserts it in place again. This would hopefully cause the browser to reload the player.

var p = $("#ply");
p.replaceWith(p.clone().attr("flashvars", p.attr("flashvars") + "/234983"));
