Can you transport a Javascript object to server and receive it in the same state?

- by zorglub76

I'm considering creating a simple remote debugging application for Javascript. Actually, I want to provide an object to Firebug Lite and let it do all the job. So, can I get an object from one page, serialize it, send it to server and then to another browser and finally see the same results in Firebug Lite (on that other client) as I would see on the first browser (with doing "console.dir(obj)")? Is it possible to do?

I've recently read the Yahoo manifesto Best Practices for Speeding Up Your Web Site. They recommend to put the javascript inclusion at the bottom of the HTML code when we can. But where exactly and when ? Should we put it before closing </html> or after ? And above all, when should we still put it in the <head> section ?

Why does the month argument range from 0 to 11 in JavaScript's Date constructor?

- by Agnel Kurian

When initializing a new Date object in JavaScript using the below call, I found out that the month argument counts starting from zero. new Date(2010, 3, 1); // that's the 1st April 2010! Why does the month argument start from 0? On the other hand, the day of the month argument (last one) is a number from 1 to 31. Are there good reasons for this?

How to check if an element is really visible with javascript.

- by Macha

In javascript, how would you check if an object is actually visible. I don't just mean checking the visibility and display attributes. I mean, checking that the element is not visibility:hidden or display:none underneath another element scrolled off the edge of the screen. EDIT: For technical reasons, I can't include any scripts. I can however use prototype as it is on the page already. EDIT 2: This is no longer neccesary, but I'd still find an answer interesting)

How to use JavaScript to measure how bright a users monitor is ?

- by HankV

I've noticed that the brightness of computer monitors drastically varies between computers. As such, this changes the look of web pages greatly. Is there a way to use JavaScript to automatically detect how bright (or dark) a users monitor is so that I can adjust my web page colors accordingly? UPDATE Please note that I do not want manual user involvement. I want this detection to be automatic so that users don't realize I dynamically change the color palette automatically based on the brightness/darkness of their monitor.

How can I create a Zerofilled value using JavaScript?

- by Wilco

What is the recommended way to zerofill a value in JavaScript? I imagine I could build a custom function to pad zeros on to a typecasted value, but I'm wondering if there is a more direct way to do this? Note: By "zerofilled" I mean it in the database sense of the word (where a 6-digit zerofilled representation of the number 5 would be "000005").
