Hello all,

I have a cookie set with 4 values i.e.

cookie = value1::value2::value3::value4

trying to strip the values but can not get to the 3rd and fourth value... here is what I'm trying....

var setlinknames=getCookie('Setlinknames');

var setlinkname1;
var setlinkname2;
var setlinkname3;
var setlinkname4;

if(setlinknames.indexOf('::')==-1){
setlinkname1=setlinknames;
setlinkname2="";
setlinkname3=" ";
setlinkname4=" ";
}
else{
setlinkname1=setlinknames.substring(0,setlinknames.indexOf("::"));
setlinkname2=setlinknames.substring(setlinknames.indexOf("::")+2, setlinknames.length);

<!-- works to this point the 2nd value is returned for 3 and 4-->

if(setlinknames.indexOf('::')==-1){
setlinkname3="";
setlinkname3=setlinknames.substring(setlinknames.indexOf("::")+4, setlinknames.length);

if(setlinknames.indexOf('::')==-1){
setlinkname4="";
setlinkname4=setlinknames.substring(setlinknames.indexOf("::")+6, setlinknames.length);
}



out put...

Value1 Value2:::: Value2:::: Value2::::

Please what am I missing ??

Thx
Erick

This looks like a job for regular expressions - a much feared and misunderstood tool available in Javascript...

For example if your string looks like this...
var str = "value:1::value 2::value3::value4";

then
str.split(/::/);

returns an array of four strings:
["value:1","value 2","value3","value4"]

Note: I added the single ':' to show that split(/::/) splits only on double : boundaries.

All right !!!

var setlinkurlcrumbs = setlinkurls.split("::");

var setlinkurl1 = setlinkurlcrumbs[0];
var setlinkurl2 = setlinkurlcrumbs[1];
var setlinkurl3 = setlinkurlcrumbs[2];
var setlinkurl4 = setlinkurlcrumbs[3];

Works exellent...

now trying to get a hrefs to work...


using.. want is to TARGET

the setlink url is set now as
http://www.global411.net target=”content

setting the <a href=" as hard code so the cookie filles the center of the href...

then hard coding the "> in the linkurl script to finish the href..

won't link or the " for the target comes up as a black block not a " so I'm guessing it is not reconizing it..

<td>

<a href="<script language="JavaScript" type="text/javascript">
document.write(' '+setlinkurl1+' ">');
document.write(' '+setlinkname1+'</a> ');</script>">

&nbsp; &nbsp;
</td>


Thx..

<a href="<script language="JavaScript" type="text/javascript">document.write(' '+setlinkurl1+' ">');document.write(' '+setlinkname1+'</a> ');</script>">

Hmmm. Might be a fine model in ASP, but HTML and Javascript don't work like that.

sounds like what you want is more like this...

<a href="javascript:void 0;" id="myLink">Watch this space!</a>

then when the HTML has loaded (use onload event on the <body> tag)
var oA = document.getElementById('myLink');
oA.href = setlinkurl1;
if ( oA.text ) oA.text = setlinkname1;
else oA.innerHTML = setlinkname1;

I'm sorry I do not understand ...:confused:

OK, the problem with saying...

<a
href="<script language="JavaScript" type="text/javascript">
document.write(' '+setlinkurl1+' ">');
document.write(' '+setlinkname1+'</a> ');
</script>"
>

is that it's not good HTML, and browsers will get confused - particularly with all the quotes.

What you need to do is set up your link (the <a> tag) with dummy values and some unique ID and then once the HTML page has loaded, fill in the values afterwards.

e.g.

<html>
<head>
<script language="Javascript">

var setlinkurlcrumbs = setlinkurls.split("::");

var setlinkurl1 = setlinkurlcrumbs[0];
var setlinkurl2 = setlinkurlcrumbs[1];
var setlinkurl3 = setlinkurlcrumbs[2];
var setlinkurl4 = setlinkurlcrumbs[3];

function Setup()
{
// get a reference to the link object below.
var oA = document.getElementById('myLink');

// set the href on the link
oA.href = setlinkurl1;

// set the text of the link
if ( oA.text ) oA.text = setlinkname1; // netscape 4 & up
else oA.innerHTML = setlinkname1; // most other browsers
}
</script>
</head>
<body onload="Setup();">
<a href="" id="myLink">Watch this space!</a>
</body>
</html>

Ok..

before I set all this up "THANK YOU"

this seems really close..

document.write('<A HREF="javascript:void.content.frames.location.href='+setlinkurl1+' "> ');

just getting line: 1 char: 5 Error: syntax error

???

Thx

It's probably the '.' after void in the statement "javascript:void.content.frames..."

If you're happy writing the link out in full, how about...

document.write('<a href="' + setlinkurl1 + '">' + setlinkname1 + '</a>');

This would be fine... I can get it to link but it is targeting the content frame that I can not get...

got it.... was simple when I looked at it again this morn, :rolleyes:

document.write('<a href=" '+setlinkurl2+' " target="content">');


ok now in the scripting ig the value is "null" notthing defined how do I get it to display notthing ?? no null or undefined or anything unless there is somthing to display ??/



Thx,
Erick
