Manipulating the DOM during page load.

[Peter Michaux]

Hi,

With the Yahoo! UI Event library it is possible to poll the DOM as the
page loads for the appearance of a particular element. When that
element is found a callback function executes. In Flanagan's book he
warns that some JavaScript experts say this is bad practice because it
is not standardized. I've tried the YUI technique only a little and
like the idea for some pages to make certain parts interactive before
all pictures etc have been loaded. Does anyone here have info about
when this technique fails?

Thanks,
Peter

I think it can lead to some misconception.
For example, you absoluty need to call a function as soon as the element is
loaded, but this function would call another one, whose job would be to inspect
the DOM structure. As the page isn't fully loaded, it can lead to some errors.

In fact, that doesn't happen everytime, but the fact that there MAY be a little
flaw is to take care of.
