Cookies - Recalling

[bigal]

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


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!

in your cookie script there will be the part where cookie is read,thats where,you put that part in all of the pages and you will see helllo name in all of the pages.

Yes agreed, but which bit?

script:



<script>

}

}

var now = new Date()

var name = getCookie("name")
if (!name)
name = prompt("Please enter your name:", "BiG Al")
setCookie("name", name, now)
document.write("Hello " + name + "!")

Which bit is the recall bit??? :confused:

[Khalid Ali]

function getCookie(name) {
var prefix = name + "="
var cookieStartIndex = document.cookie.indexOf(prefix)
if (cookieStartIndex == -1)
return null
var cookieEndIndex = document.cookie.indexOf(";", cookieStartIndex + prefix.length)
if (cookieEndIndex == -1)
cookieEndIndex = document.cookie.length
return unescape(document.cookie.substring(cookieStartIndex + prefix.length, cookieEndIndex))
}

where parameter
name="name"

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.

As a mater of fact good idea...

[bigal]

How would you do that? :confused:

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:


:cool:

I will open a new topic on how to have Javascript cod in a .js file and insert it wherever needed! :)
