Hi all...

Have any of you tried to use cookies yet!

OMG - is it just me or are they impossible to work out.

I Have tried several methods all found on the net and all based around the same functions setcookie(), getcookie() and deletecookie().

The only thing is I cannot get them to work. Whenever I put them in a <script> tag the page always displays with errors and I cannot figure out why.

All I need is a cookie that will store a single colour value.

Any ideas?

Thanks in advance and hope!
Neil

you may need to rename your page as a .php page instead of a .html page to get the scripts to run Then put the setcookie() inside <?php ?> tags rather than <script> tags???

This might help you

Thanks to Tom and Fe Pixie for your replies.

Fortunately I have managed to work it out. None of the samples actually worked correctly so after much head scratching and coffee in a cup , I re wrote the original samples I found as it turns out you do not need 'php' to use cookies. HTML and Javascript and a little good luck work just fine.

So I have working cookies and learnt a hell of a lot about Javascript in the process

All I have to do now is figure out how to get all my functions to call correctly from a seperate script file

Thanks again,
Neil

You could load the script in the head section

and call the function from withing the page body

Or call the function from an onclick event.

Thanks for your reply Tom... I did not make it very clear!

I have managed to get my functions in a script file with no problem. The problem lies with passing variables from one function to another from within the script file.

It is hard to explain, let me try. Two functions - A and B. Both stored in a script file.

I call function A with a variable, which in turn calls function B - the problem is it does not seem to pass the variable with it and I don't know why. The VB equivalent would be local and global variables (I LOVE coding in VB as well by the way!) but I don't know if JScript or HTML can use persistant variables.

It is not vital that they are in a script file, it is just that I will be using these functions (6 of them) a lot and it would cut down on clutter as each HTML page will need all 6!

So if you do have any ideas on the solution - I am all ears.

Neil.

PS. One thing I use <script language="javascript"> and then the ref to the script file. Would this make any difference to the option you suggested?

External scripts are fine as long as you declare the script in the head section of the html, it's loaded and ready to be used. The priciple of passing a variable to any javascript function, and returning a value, is just like in VB.

W3Schools is a great source. Check out these pages on JS Functions.

Thanks Tom and sorry for the delay in replying.

I had declared in the body section instead of the head. DOH!

All working fine now.

Thanks again.

LOL, I've been there a thousand times, myself. Glad you got it working.
