sending variable to a new page

what im trying to do is send a number to a page that the user opens im trying to do it in java what i have so far is:


page 1

<a href = "http://wherenewpageis.html?send=1">test send</a>

page http://wherenewpageis.html

<script language = "javascript">
document.writeln(send);
</script>


im not shure if im even doing it remotly right im just kindof guessing that the ?send=1 makes a varble on the page its loading called send and sets it to 1 but it seems thats not the case or if it is im doing something else wrong please tell me how to do it or what im doing wrong.

thanx

No it doens't make a variable on the page (unless you are using a server-side method to retrieve it rather than JavaScript). You will need to use a script to find all the arguments in the query string. I think I have one on my site at http://www.rickbull.co.uk/tutorials/...t%20Downloads/ which you can use if you like.

thanks for the script rick.

now i have another quaestion how can you detect if they havent put any parameter in the adress

Well you could make up another function from the script I gave you. Let me do that, reupload it then I'll post back here.

OK, I've updated it http://www.rickbull.co.uk/tutorials/...t%20Downloads/ - there's now a new function hasArgument, just pass in whatever argument name you want. E.g. this will return whether the argument 'user' is present:

Code:

---

alert(hasArgument('user'));

---

ok got it thanks again
