I am not getting this at all , is there maybe somewhere else that explains it in simpler terms or in another way. Doesn`t help one is going through the motions and not even getting the given exercises right. What should I do?

You can always google for Javascript tutorials. It may just take another viewpoint to understand it. W3 schools http://www.w3schools.com/js/default.asp is always a great place to start.

No!!! Don't say that Lindy! I had to have a completely unplanned operation and I'v been off my feet for 2 weeks! I'm so behind and haven't even started to look at Java scripting! sad smiley

Good luck- I'm sure with a lot of patience and perseverance we'll get through it! thumbs up

My question is this:
I have now joined Lynda.com and am going through those javascript tutorials. I am still struggling to understand where one gets all the lines from and how they fit in together and what goes where. Is this normal for first timers with Javascript? Is it okay to not really know what is going on and do this assignment , so that when I do the assignment I can copy javascript from other sites or wherever I can get hold of it from , I am feeling a bit desperate at the moment and time is running out?

Hi lindy

If it makes you feel any better, javascript, in the beginning, is not for the faint hearted. I can try and help you ....

For your rollover menu use the Javascript lesson 4B.

If you have done task 4B and got it to work successfully, why not copy and paste the javascript, as it is, into a new basic html file. If there is nothing on the page except the required tags eg. 
Language: HTML
<html><head></head><body></body></html>
, you can play around with it easier.
All you would need to change would be the image names and perhaps the folder, depending on where you have put the images.

In the head section of the page between 
Language: HTML
<script></script>
tags you need to define the function (tell the browser what to do) when someone mouseover the menu image in the 
Language: HTML
<body>
of your page. That is over simplified but about the best I can explain it.
In each of your links 
Language: HTML
<a>
you then add onMouseover and onMouseout events, which call the functions defined in the script in the head of the page.

Once you have got the javascript working on a page with nothing else on it to distract you, then add it to your portfolio page.

I hope Mac corrects me if I have got this wrong!

It is perfectly acceptable to copy javascript from other sites and use it. You may need to adapt it a bit though.

Is anybody else having problems using all of the javascript capabilities in browsers like chrome and firefox? Only certain of the effects work in these browsers, but I am not having the same problems in internet explorer.

Regarding the post by Phoenix, I have also found certain problems in the Zoo tutorials (inculding the "solution demos"winking smiley when using Firefox & Chrome, whereas Explorer always works correctly. Firefox is my 1st choice browser. I was surprised to have such basic issues.

I am a bit confused by the inclusion of a "menu system that makes use of roll-over images" for the assignment. What exactly do we have to do here? Can I have a list that turns into an image with text. So that when I rollover the item in text on the list , a photo and some text appears?? OR have the image and when rolled over text appears and then obviously have no list??

I have read in the tutorial letter that we don't need to report our progress back on the forum for JavaScript. Is there anything we do need to submit to show that we have worked our way through the chapters?

Thanks for the help!

An image is replaced by another image, e.g. a green button with some text on it is replaced by a red button with the same text on it, or the button stays the same but the text on it changes.

Hi Everybody

I'm not sure if anyone has come across this error but I'm not sure how to fix it and getting very frustrated at this stage!

I have completed activity 4B successfully and then adapted the code to my portfolio website however when I mouse over the first link, the image belonging to the second link changes. Same happens for link two, when I mouse over it, the image belonging to link 3 changes into the image that is supposed to be assigned to link two and then finally when I get to my third link and mouse over and then off it I get an error on page message telling me to check the following (namely the two lines with document.images...): 

Language: Javascript
function activeLink(imgnum) 
{
document.images[imgnum].src = rollimgs[imgnum].src
}
 
function inactiveLink(imgnum)
{
document.images[imgnum].src = rollimgs[0].src
}

Am I completely blind and missing something?!
Please help!

I have googled , sat for hours and still I don`t seem to be getting this javascript. What should I do now? All my assignment needs is those 2 javascripts.

I have managed to do the rollovers using :
<td><a href = "thingsToDo.html" onmouseover="document.golf.src='golf1.jpg'" onmouseout="document.golf.src='buttonGolf2.png'">
<img src="buttonGolf2.png" width="100" height="100" name="golf" alt="Club Me!" border="0"></a></td>

I know this is not really the right way of doing it but I am so stuck? I don`t really understand the way of putting it in the head section , I have tried. Where can I go to find out what to do?

Lindy, I know how you feel...and although I don't really understand this 100%, I followed the steps of Task 4B-1&2 and managed to get it to work, although on the wrong images. So perhaps I am not the right person to give out advise at this stage but if you follow the steps, changing image names and adapting the array to the number of images you have...it should work.

I wish that someone else will suggest otherwise so we can get this to work.
Rowena also provided a nice breakdown above.

Hang in there!
