The slider is complete, works very well. The only problem is that the captions are just not appearing properly. I had a situation where the captions did work but they had to be coming in from the slideOut functions but what i want is for it to be displayed when the person hovers over the image. This is what it looks like at the moment... This is when the caption is coming from the top. i would like to implement Code: http://web.enavu.com/demos/caption/ or this Code: http://www.sohtanaka.com/web-design/examples/image-hover/ Doesnt matter which one into my slider when an image is hovered over (not the thumbnail) the actual image, then the caption covers the whole image displaying whatever text...

NYSH Hi, I am hoping a JS expert might be able to explain this function. It is part of a larger programme. The program basically checks which profile the user selects and sets the html to display in certain colours. I am still trying to understand programming. The part I don't understand is the SetCookie("profile", i); What is this function telling the SetCookie function to do? Why does this work? Really grateful for any info.Thanks in advance. ************************************************* function updateProfile() { for (var i=0;i<document.form1.profile.length;i++) { if (document.form1.profile[i].checked) { SetCookie("profile", i); } } document.location="cookie3.html"; } I have inherited some code, and cannot get it to work. Note the bold section in the OBJECT tag below. I believe this is where the issue is.

What am I missing? Thank you in advance. 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 Hello! 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. 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 Guys, I am new at JavaScript and start to do some tutorials.What I am trying to do here is prompting user to input a name and if the name was valid the page(document) will display with all objects like the button.But if user enter a wrong name then the button will be disabled!

Hi Guys I am trying to modify the functionality of my page. I want to be able to activate this piece of code using another javascript function.

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... All -- I have a JavaScript config file called gameSetting.js which contains a bunch of variables which configures a particular game. I also have a shared JavaScript library which uses the variables in gameSetting.js, which I include like so: <script type="text/javascript" src="gameSetting.js" ></script> <script type="text/javascript" src="gameLibrary.js" ></script> In gameSetting.js I have: $(document).ready(function() { // call some functions / classes in gameLibrary.js } in Firefox, Safari, and Chrome, this works fine. However, in IE, when it's parsing gameSetting.js, it complains that the functions that live in gameLibrary.js aren't defined. When it gets to parsing gameLibrary.js, the variables in gameSetting.js are reported as not being defined. I've tried dynamically bootstrapping the gameLibrary file using this function in document.ready for dynamic load... $.getScript("gameLibrary.js"); However, the same problem still happens in IE, where when it parses the files individually it's not taking into context the file/variables that came before, so it's not an out of load order problem. My options a 1) collapsing all the functions in gameLibrary.js and variables in gameSetting.js into one file. However, this is not practical because this is dealing with literally hundreds of games, and having a gameLibrary.js in ONE location for ONE update is what makes most logical sense. 2) figure out a way to get this to work where variables in file1 are accessible to file2 in IE (as it seems they are in other browsers). jQuery seems to be able to have multiple plugins that all refer to the based jQuery-1.3.2.js, so I know there is a way to get this to work. Help appreciated. Nero I wrote a log function that took note of various function calls. Thinking that functions are first class objects, and objects have properties, I made the name of each logged function a property of that function, e.g., brightenInnerPara.name = "brightenInnerPara"; Every browser I tried (Firefox, MSIE, Opera, Chrome, Safari) accepted the assignment, no problem. In Firefox and MSIE, the result was what I wanted: brightenInnerPara.name == "brightenInnerPara" But in the others, the result was: brightenInnerPara.name == null Question 1. Which Javascript is correct here? I favor Firefox and MSIE, not merely because they were willing to give me what I wanted, but also because it makes no sense to accept an assignment statement without throwing an error and then give it a null semantics, like Chrome, Opera, and Safari did. I found a workaround, using assignments like this: brightenInnerPara.prototype.name = "brightenInnerPara"; To my surprise, that worked in every browser. But I don't know why. It seems that such assignments are enough to cause each function to have its own distinct prototype. Question 2. Just how inefficient is my workaround, and why does it work? I'm learning JavaScript. My suspicions for all these years would be I'd hate it, and it I was right. It seems I have to write half a page to perform something so simple. Anyway, a question: Do I have to end **** with a ; always? {example;} I am really struggling to do something really painfully simple he just create a class in javascript!! I tried this, based on a google search: Code: function myclass() { this.myvar = 1; this.mymethod = function() { alert(this.myvar); } } But, of course, this.myvar in mymethod is not the same as this.myvar in myclass. So I did another google search, and tried this: Code: function myclass() { this.myvar = 1; this.prototype.mymethod = function() { alert(this.myvar); } } And I get the error report: "this.prototype is undefined". So I tried parent and super in place of this within mymethod, but both of those throw up an "<whateve> is undefined" error too. I give up!! Is it just me, or is trying to write OO Javascript really like trying to grapple with a slippery fish?!! Something that should be really painfully simple is proving to be a nightmare ... I run a small nonprofit org, and am looking to upgrade our site to something cleaner like UNBOUNDARY'S website he http://www.unboundary.com/ Don't laugh, but I build our website with Microsoft Publisher, so I don't know any Code or Javascript. Is there any way I can have this "middle scrolling frame" like they do without having to know code. Perhaps an easy cut & paste code I can embed to give me that middle frame. Any assistance you can give is appreciated. Thanks, DOC |
