Cookies – Recalling

Copy linkTweet thisAlerts:
Sep 01.2003

I have received nothing but Helpful replys and advice here! So I have decided to post My next challanging Problem ?

Save the attached file as htm and open, enter a name and you get hello <Name>

Thats all well and good, it remembers your name.

But how would you put the name in the another HTML document, EXAMPLE.

Page opens – name entered – page says hello <Name>
Link downloads clicked. Page says, Hello <Name>
blablabla <name> blabla b…….<name>

In other words, how can you utilise just the recall part of the script, or do i have to insert the whole 5kb script wherever i want the name to be displayed?

Problem #1:
If cookies are disabled they will get hello null ?
Problem #2
If the whole script is in all over a page 6 times, they will have to enter there name 6 times if cookies are diabled or get null!

prov #3 Away from that (who cares if the end user has cookies disabled – ill ask them to enable it)the main prob is SIZE!!!! its a six k script, can i just utalise the recall part.

Thank,
BiG Al!

var name = getCookie("name")

if (!name)

name = prompt("Please enter your name:", "BiG Al")

setCookie("name", name, now)

document.write("Hello " + name + "!")

@Alien_ManSep 01.2003 — Why not just put it in a .js file and write it once and call it when ever you need it from what ever page you need to use it in.

[B]Why not just put it in a .js file . [/B][/QUOTE]

:-)

As a mater of fact good idea...

@bigalauthorSep 02.2003 — How would you do that? ?

Would you put the entire cookie code in a .js file.

How do you call it in a normal html file ??

I will have to experiment! :rolleyes:
