I want make a custom list of youtube vedio. I use javascript code. Why I can not send a value from onclick? It show fault: document.getElementById(...)' null...Thanks.
Of the major browsers, only Firefox lets you dynamically change the source of an embedded flash movie. For this reason, your code will not work in Internet Explorer, Chrome, or Safari (or rather, it will change the source, but to no effect). To get it to work in all browsers, you have to completely rewrite the embedded object to the DOM, in its entirety.
The easiest way to do this is to use the swfobject javascript library. This library not only encapsulates all the functionality to make it very easy to use, but also ensures cross-browser compatibility and deals with edge cases (like if the browser does not have flash installed).
