We have created a progress indicator and when we show the progress indicator we set the opacity filter of the div.
oDiv.style.filter = 'Alpha(Opacity=30)'

This is causing the increase in memory usage. Is there an alernative to the above approach?
One alternative is to use Alphimageloader filter to load a transparent image. The issue is that one can perform operations like mouse click on the document.

Any Ideas? What does DOJO use in thier load indicator?

Thanks
Does DOJO offer any help in JS profiling?
Which is the best tool to detect memory issues with the JavaScript code for IE and FF.
I looked at memory leak detector and tito for IE but they are not very reliable.

Any Ideas?
Congrats on really geeky store application. Here are my comments on the questions you asked

1. Would your mother feel comfortable using this application?
I don't think my mom would feel very comfortable using the application first time. Lot of things are taken for granted by a internet savvy user but may not be very usable for a occasional user like our parents. Some things would be overwhelming the first time. However, I think on second and third visit they should feel comfortable.

2. How difficult or easy would this be to write this in your favorite RIA language?
I am comfortable with HTML and libraries on it. Using prototype or DOJO it should be easy to design this application. Especially adding effects should be easy. It would take some time though.

3. What do you like or dislike about this application.
I feel there is too much information on one screen.

4. What features would you like to see added?
I guess a better product catalog.

5. Any misc. things that you might want to comment on
Some of the things in the demo app are not functional. For instance the horizontal bars on the left. The movie at the right bottom doesn't load. I got some JS errors when I clicked on the bars on the left. Also it didn't work very well on Firefox. i guess some of this was because it is a demo app.
I really like the part how it works very well with the keyboard only interface. Also the way the application highlights the field in focus is great!

How is the DHTML generation by Open Lazlo. Last time I played with it the DHTML that gets spit for a small simple page is enormous. IS there a plan to improve that?

Does jQuery provide animation and effects support? Are there any extensions built on top of jQuery for the same?


Thanks

Yes, this is about the issue with the for .. in loop. What should we do for existing code and in MashUps where there could be such code.

Thanks

Hello, We have a problem that is related to what is described on
http://prototypejs.org/api/array .
We have added prototype.js into our product and just adding it breaks
existing code which relies on associative arrays.

We can change some of the arrays to follow the prototype syntax.
However, I m wondering whether there is a work around to this problem
especially because there is customer code that we can't change. Also
with porotype our application won't work in MashUps.

I am sure this is not the first time some has encountered this
problem. This is really a blocker for us right now. Any help or input
is highly appreciated.

Thanks

It looks similar to prototype. How would one compare the two?

Recently I read about a technique called CSS Sprite. I think it is very useful in improving performance of the web sites. Are there other CSS techniques to improve performance?

Thanks
Does the book cover tips on how to write CSS which works accross multiple browsers? We are in process of making our application work in FireFox and we are facing a lot of CSS issues.

What is the best way to test the JavaScript APIs. With AJAX lots of functionality now lives in the web tier. Does the book cover some approaches for the same?

Does the book cover dojo and prototype ?

Thanks
I are evaluating the above two libraries.
I think Dojo is popular with lots of features and Prototype is simple.
Any opinions ?
