JavaScript - Javascript Book
Would like to start learning JavaScript and would appreciate any books based on JavaScript that forum members would care to recommend. Thanks all
Similar TutorialsHi, I have a very old book on JavaScript, and just wondering if it would be wise to start from it. The book is: SAMS Teach yourself JavaScript in 24 hours - Second Edition (covers JavaScript 1.5) Let me know guys because I can get cracking on with it if so! What I need to know is whether or not JS has been updated since? Hello, I was just wondering if anyone knows of a great javascript book to buy. I am looking for something super duper hard core. I would love it to have documentation galore that includes all of the AJAX and DOM and XML. You know... like a javascript BIBLE. Something thick and comforting. Something that makes you feel all warm and toasty inside just knowing that it is there. So if I start running into some problem I can just glance at the book and rest assured that if the problem exculates not to fear. I have .... THE BOOK. Does anyone have any suggestions? Thanks, Michael I have come to the conclusion that this book title sux "New Perspectives on JavaScript, 2nd Edition " Is there a better book I can use where I can copy the sample programs that the book uses, that actually has good modern javascript technique, and has the other code that goes along with it like the html, the css, and the .jpgs all on the cd that comes with the book or something? "Professional JavaScript for Web Developers (Wrox Programmer to Programmer)" by Nicholas C. Zakas is a good book title it definitely clarified that crappy text book that my university gave me, but I'm ready to take the next step and start using sample code and apply the concepts I learned from that book. Please recommend anything I would need to be ubber programmers like all of you guys.
I have to take more javascript programming classes and I'm really not good at it. I desperately need help. I own Visual Basic, but it's a little difficult to use. What is the best book, online resource, and software for programming in javascript?
I typed this code straight out of the book and it just doesn't seem to work. I have the headlines on the left side and when clicked the contents of the headline is supposed to show up in the text box on the right. Well, needless to say, nothing appears. Please someone tell me what I am doing wrong. I am not the only person in the class having this issue. Thanks a million.

So I am looking for a book that basically goes from the very basics to middle level of java programing, but one that is up to date, and that explains everything, not like some of the books that just throws code at you and expects you to understand why you are making the class public and why it extends javaplugins, just something in depth that really explains why for everything.

I am trying to find a script that allows you to open multiple browser tabs and then close each of those tabs, either one by one or all at once. Does anyone know how to do this please? Thanks so much for your help. I want to have another go at Javascript. I have several books on the subject but I find that my eyesight is a major problem. Therefore I want to try an on-line solution, preferably free. I have Googled, but there are so many that I am almost dizzy with the choices. Perhaps someone could recommend one. Not too fussy visually. My knowledge is VERY basic. Frank Does anyone know how to make URL links that use Javascript still work when users have Javascript disabled on their browser? The only reason I'm using JS on a URL is because my link opens a PDF file, and I'm forcing it not to cache so users have the latest version. I tried the <script><noscript> tags, but I'm not sure if I'm using it correctly, as my URL completely disappears. Below is my HTML/Javascript code: <p class="download"> <script type="text/javascript">document.write("<span style=\"text-decoration: underline;\"><a href=\"javascript:void(0);\" onclick=\"window.open( 'http://www.webchild.com.au/mediakit/Direct_Media_Kit_Web.pdf?nocache='+ Math.floor( Math.random()*11 ) );\" >The Child Magazines Media Kit</a></span> (PDF 1 MB) ");</script> <noscript><span style="text-decoration: underline;"><a href="http://www.webchild.com.au/mediakit/Direct_Media_Kit_Web.pdf" >The Child Magazines Media Kit</a></span> (PDF 1 MB)</noscript> </p> Thanks for any help, Michael Hi, I have the following code snippet: test.html ====== <script language="javascript" type="text/javascript"> var testVariable = "test"; </script> <script language="javascript" type="text/javascript" src="test.js"> </script> test.js ===== var testVariable = window.top.testVariable; In firefox, I'm able to access testvariable defined within test.html in test.js.

Hey, I've got to make the values of some textboxes change the co-ordinates of my sprite on a canvas and havent a clue on how to do it, Here is my form with the two textboxes and submit button: <form> x: <input type="text" name="x" /><br /> y: <input type="text" name:"y" /><br /> <input type="submit" value="Submit"/><br /> </form> And i need it so that they change the values of these: //this shows where my sprite will start on the canvas var block_x; var block_y; searched the internet for hours and cant really find anything i understand or works. any help is much appreciated I got an index.php Code:
<html>
<form action="bacakomik.php" method='post'>
<select name="kodekomik">
<option value='../komik1/|23'>Judul Komik1</option>
<option value="../komik2/|20">Judul Komik2</option>
<option value="../komik3/|10">Juduk Komik3</option>
<option value="../komik4/|20">Judul Komik4</option>
</select>
<input type="submit" />
</form>
<?php
echo ('<select>');
echo ('<option value= "'.$i.'">'.'Page '.$i.'</option>');
echo ('</select>');
?>
</html>
As you can see, each of the option brings specific value "../komik1/|23" komik1 is a directory | is a delimiter 23 is the pages in one chapter and can be considered also as how many images are there on a specific directory This is my bacakomik.php Code: <?php
$dirkomik = $_POST['kodekomik'];
$exploded = explode("|", $dirkomik);
echo ($exploded[0]); //picture directory
echo ("<br>");
echo ($exploded[1]); //total page in the comic
$pagecount = (int)$exploded[1];
//Take last posted value, process it right away
echo ('<FORM name="guideform"> ');
echo ('<select name="guidelinks">');
$i=1;
do {
echo ('<option value= "'.$i.'">'.'Page '.$i.'</option>');
$i= $i+1;
}while($i <= $pagecount); //Printing option and select
echo ("</select>");
?>
<input type="button" name="go" value="Go!" onClick="document.getElementById('im').src=document.guideform.guidelinks.options[document.guideform.guidelinks.selectedIndex].value+'.png';"> </FORM>
<img src="img0.jpg" id="im">
With the current code on bacakomik.php, I only can change the img src of id "im" in the same directory only. What I want is that the Javascript could "add" the "$exploded[0]" variable so that the picture can be loaded from different directory. Anyone can do this? I believe that the fix should be somewhere on input tag inside OnClick, or do you know where? Anyway, I found this on the net http://p2p.wrox.com/php-faqs/11606-q...avascript.html Please help me to those who can... Hi Guys I am trying to modify the functionality of my page.
