writing information to a div

[gomzi]

hi,
I have written a small script that will display data in a div tag ...the data to be displayed will change every two seconds.

The problem that i am having with this script is that,
in internet explorer i get an error "expected )" [This error does not occur every time i run the script.say once in every 5 runs it appears. Try refreshing the page again and again].

in firefox, nothing gets displayed...i am stumped on that!!


The code :

var names;
var i = 0;
function displaynames(na me)
{
names = name.split("### ");
heading.style.v isibility="visi ble";
heading.style.d isplay = "block";
heading.innerTe xt = names[i];
i=i+1;
var t = setTimeout('sho wnames()',2000) ;
}
function shownames()
{
if (i<names.length )
{
heading.innerTe xt = names[i];
i=i+1;
var t = setTimeout('sho wnames()',2000) ;
}
else
{
i=0;
heading.innerTe xt = names[i];
i=i+1;
var t = setTimeout('sho wnames()',2000) ;
}


The input to displaynames is in this format -> "wow###yipe e"

any help would be appreciated...

thanks,
gomzi.

hey guys...i think i have got a pretty good idea of whats going wrong here...

I have some strings like this-> windows xp 'microsoft' in the database..

so when am trying to display them, i get an error saying expected ')'

i.e. it wrongly considers the single quote as the end of the string...

is there anyway how i can overcome this?

hi pal
first u are missin a }
at the very end!!!

and instead of using
i=i+1;
use
i++;
i can help u with it ,when i understand the way u want it.!
so do u have an textbox for entering names seperated by ###
and u want to write them in a div every 2 sec
Or
do u have an array of names?
and u want to write them in a div every 2 sec

im curious
peace

thanks mate....
ya. i have the } at the end..forgot to copy it here.

i have an array of names. These names have been put into the array by separating them .... i.e. say tom###jerry has been put into two positions in an array , one containing tom and the other jerry.

hi pal
eh could you post a bit of this array
im having trouble understanding it
is it like

names = new Array();
names[0]='tom';
names[1]='jerry';

or

names = new Array();
names[0]='tom###jerry';

which would be very weird
ps firefox does not support innerText use innerHTML instead
hahaha
well peace to u

well peace to u

yup..its of the first type.tried innerHTML. firefox didnt display that either!!

[DutchKingCobra]

so if im correct
u have an arra like this:

names = new Array();
names[0]='tom';
names[1]='jerry';

and u want to write it into a div or span like this

tom###jerry

every 2 sec?

names = new Array();
names[0]='tom';
names[1]='jerry';

and u want to write it into a div or span like this

tom###jerry

every 2 sec?

nope....its something like this...

initially i have this - > tom###jerry in a variable say var1 (string)

then,

i separate it into tom & jerry and put it into a variable named names which is an array...
something like what you guessed..
names = new Array();
names[0]='tom';
names[1]='jerry';

now, i want to display these two items alternatively every 2 seconds.

but the problem is that in case the string is something like say...

tom###je'rry'

then when i pass this string to the displaynames function,
i get an error that the expected ')' aint there.

[gomzi]

And one more thing....
The string can contain single quotes as i just showed...

or

double quotes, like -> tom###je"rry"

or

any other character for that matter...

so, is there a way of encoding the strings so that it wont create a problem in any case?

[DutchKingCobra]

hmmm thats a difficult

are the strings predefined or is it userinput?

take a look at this

instead of a single space?
peace m8
