Editorial Review :
Pro JavaScript Techniques is the ultimate JavaScript book for the modern web developer. It provides everything you need to know about modern JavaScript, and shows what JavaScript can do for your web sites. This book doesn't waste any time looking at things you already know, like basic syntax and structures. Expert web developer and author John Resig concentrates on fundamental, vital topics—what modern JavaScripting is (and isnt), the current state of browser support, and pitfalls to be wary of. The book is organized into four sections: - Modern JavaScript development using JavaScript the object-oriented way, creating reusable code, plus testing and debugging
- DOM scripting updating content and styles, plus events, and effect and event libraries
- How Ajax works, overcoming problems, and using libraries to speed up development of Ajax applications
- The future of JavaScript looking at cutting edge topics like JSON, HTML5, and more
All concepts are backed up by real-world examples and case studies, and John provides numerous reusable functions and classes to save you time in your development. There are also up-to-date reference appendixes for the DOM, events, browser support (including IE7), and frameworks, so you can look up specific details quickly and easily.

Question : How do you fix JavaScript errors using debugger/developer tools, in interent explorer?
As of two days ago I can no longer attach things or send emails using my university email account with internet explorer because of JavaScript errors. I think it is a runtime error?! Anyway, I kow how to open the debugger from selecting it from the tools menu in IE and it does detect problems with this website, but I have no idea what I need to do with the debugger to fix them. Can you please help. Thanks.It is meant for anyone to use. Look at developer tools in the dropdown menu of tools. It isn't an ie problem, its my pc which I can fix.
Answer:
I don't know what debugger you are talking about, but I'm pretty shure the tool is meant for developers, not users.Aks the administrator to fix it, and until then, you can't do much but use another browser.

Question : How do I make my javascript work for youtube?
I recently downloaded firefox and youtube no longer works on my laptop. I downloaded the most recent flash player and I checked to see that the javascript was turned on and it is. I looked it up and those were the two suggestions everyone seemed to have, but its not working. What do I do?
Answer:
If you keep getting "HELLO, YOU EITHER HAVE JAVASCRIPT TURNED OFF OR AN OLD VERSION OF ADOBE'S FLASH PLAYER....GET THE LATEST FLASH PLAYER":don't bother downloading and re-installing the latest Flash over and over and over again.You will get absolutely nowhere doing that, because that is only adding to the problem.There can really be only 3 possibilities:1) something is wrong with YouTube2) something is wrong with your cache3) something is wrong with your Flash1) YOUTUBE:Your problem may fix itself within a couple hours, or by thenext day, because YouTube often "shuts down" a bunch oftheir own servers every single day without warning anybody, in order to update all kinds of stuff. During those occasions, it's really YouTube's data transmissions of "Java" or "Flash"that are poor -- not your reception of it.2) CACHE:If the following day your YouTube is still stuck and showingyou those awful "JavaScript" and "Flash Player" messages, it's possible that your sub-directories of "temporary internet files" and "cache" memory are full, and can't take anymore.This typically results in videos being totally unable to bufferand make it onto your computer screen. "Temporary internet files" are 1000s of tiny bits of websitespermanently put on your computer's hard-drive. They'll stay there forever and ever, gradually plugging up your computer much like hair slowly clogs a sink drain, until you get rid ofthem once and for all (or at least everytime things go awry).Because your computer now has such little space in which to "cache" a video, YouTube will mistakenly think that yourJavaScript is off or that your Flash player (unable to absorbany more videos) is old -- meaning Flash 7 or older.The solution to all that is to exit YouTube (but not your web browser), then clear your "cache" of all its "TIFs", "cookies"and "history". (See below.) After that, shutdown and reboot.3) FLASH:Nothing about watching YouTube has really changed in thepast 2 years. (Technically, you could still even use Flash 8if you wanted to.) It looks like the newest Flash players arecausing many YouTubers a whole lot of grief, especially all 8 variations of version 10.It's absolutely nuts that there's 10.0.525, 10.1.218, 10.2.26,10.2.54, 10.12.10, 10.12.36, 10.15.3 and 10.22.87. Usuallymost updates are good for only 1 thing:...software conflicts.I have never strayed away from 9.47, and there are a bunchof "flashers" who still live by 9.45. Think of those 2 Flasheslike Windows XP compared to Vista. Please have a look atthe "Asker's" response to this other "Best Answer" of mine:http://answers.yahoo.com/question/index?qid=20081125075929AABZpVSIf that seems interesting to you, here is the appropriate link:http://www.oldapps.com/flash_player.php?old_flash_player=14Note 1: if you've got Google Web Accelerator or somethingsimilar to it...dump it, burn it, trash it, disable it, uninstall it, -- do everything you can to get rid of it. GWA conflicts with YouTube. Clicking "Don't Accelerate This Website" will nothelp you whatsoever. Also, most "Messenger" applicationshave a way of mucking up YouTube.Note 2: longer videos may require "Flash" and "Shockwave"in order to play properly. Other than that, avoid those sales pitches that some Yahooers may be shilling, because they are really disguised salespeople & peddlers. Their answershave nothing to do with your question, and their wares mayactually worsen your problem. Besides, what kind of idioticanswer is "Despite the fact you can't even watch or access videos, buy our downloader." [my paraphrase]Note 3: a very odd fix that once worked for me was alteringthe URL from "www.youtube.com" to simply "youtube.com"(or you could even try "ca.youtube.com").Note 4: there's always the strange possibility that you mayhave gone through the whole process of downloading Flash, BUT DID YOU ACTUALLY INSTALL IT? If you have Firefox,did you "enable" the Flash "add-on"?I hope that my information proves to be quite helpful to you.Internet Explorer 6:→ Tools → Internet Options → Delete Cookies → OK→ Delete Files → OK→ Clear History → Yes → OKInternet Explorer 7:→ Tools → Internet Options → Delete...→ Delete files → Yes→ Delete cookies → OK→ Delete history → OK→ Close (browsing history window)→ OKMozilla Firefox→ Tools → Clear Private Data[x] Browsing History[x] Download History[x] Saved Form and Search History[x] Cache[x] Cookies→ Clear Private Data NowApple Safari 3:→ Edit → Preferences→ Security (tab) → Show Cookies→ Remove All → Doneafter that:→ Safari → Empty Cache → Emptyafter that:→ History → Clear History

Question : How can i get JavaScript on my blackberry pearl? Would it be safe to download if necessary?
I just got a blackberry pearl. I wanted to get access to my bank account information on line but when i try log in in, it says: Your browser is not capable of viewing this site because it does not support JavaScript or JavaScript may be disabled. Please enable JavaScript. Were i can i get JavaScript? Or is it already on my phone, i just have to enable it? If i have to download it, will it be safe to do so?
Answer:
It depends on the bank site whether the BlackBerry Java Script will actually work.Try these solutions. Open your browser, click the menu button, scroll to Options. Go into Browser Configuration and check "Support JavaScript". Try the website. If it still doesn't work, go back into the same setting, keep Support JavaScript checked and go to "Browser Identification", select Internet Explorer. This can also be known as "Browser Emulation Mode". Now try the website. If it still doesn't work, then you're sunk. But these are the best attempts and they do sometimes work. Under normal circumstances I can't login to by bank, but with these settings mine works.Good luck.

Question : How to fix javascript errors in my windows vista computer?
My pc has javascript error message pops up. My OS is vista. Can u kindly tell me how to fix in in plain English?
Answer:
There are mainly two reasons:1. If you are getting JavaScript error when using a certain program then you can try to update the program and check if the problem is solved, or u can reinstall the program.2. If you are experiencing errors from webpage you can check if Active script, Java applets, or ActiveX is blocked on your browser settings. Check other computer if they are getting Javascript error when opening that website. If yes then the problem lays on the website itself, not your computer.If none of these solutions work, then you have a problem in your system files or registry. Registry cleaner program will scan all errors in your computer and repair them. They will eliminate all possible causes of bugs and errors. Registry easy is the best cleaner among those cleaner. U can easily fix all errors in ur pc like a pc guru:)

Question : How to use Javascript animation to change the size of a div?
Im trying to use purely Javascript to animate the sizing of a div. Basically I want the div to slide up and down when called to do so. Any help? Thanks.
Answer:
What you're talking about is a combination of JavaScript and CSS. You must use CSS relative positioning on the div you want to move, then adjust its "top" setting with JavaScript. To create an actual slide effect (and not just have the div jump around), you need to implement timers. I pasted the basic idea as a test webpage. Simply copy and paste into a blank html document. If you want to use this code to change the height of the div (your question wasn't very clear), you should replace the style.top code with style.height.Movement JS |
