The best possible option is to move inline script to the bottom of the page, along with the DEFER attribute, right?

Steve,
I have a large body of HTML that I’d like crawlers to be able to see, but that same content will be styled into a nice carousel display when JS gets a chance to run. I am trying to minimize page jumping, so I can’t wait until the JS in the footer has a chance to run.

I was planning on using a very fast inline JS– just setting the carousel container size and overflow:auto– but now you’ve made me doubt the approach.

Do you have any suggestions on minimizing page jumping and keeping page content visible without JS, also while avoiding inline scripts? :-/

Hi,

I have a question.

document.getElementById(“applet”).innerHTML = ;

From the code above,,,is it possible that the race condition occurs between the declaration of the applet object and the onload event calling to the applet’s function????

I also want to know what is the sequence of execution when we have the onload event and the inline script in the body tag

Steve, there is actually one more way to resolve huge timeout because of inline scripts execution. We can perform all critical calculations on the server and put on client only all final numbers (or final DOM tree).

Taimar – you can use ‘defer’ when your scripts operates on DOM which you don’t know if it’s full loaded or not

Are there cases where defer attribute can’t be used (some scripts won’t work etc) in inline but also in external scripts?

Yes, IE does defer script execution. I go into more detail in the actual chapter, but you can investigate this more using Cuzillion. For example: this Cuzillion test page contains a two second inline script and a two second image, but the page loads in two seconds, showing that the script was deferred and executed while the image was downloading. You could add more resources and change the configuration settings to examine edge cases you have in mind.

Steve,

Again, strong article about something important, thanks.

I have question about DEFER.
The HTML 4.01 DTD states: “UA may defer execution of script.” The magic word here is of course ‘may’.

What are your experiences with IE7? Does IE7 always/often/sometimes/hardly ever actually defer the script execution?
