How can I click on a joke and have a new joke appear?

j = [
"haha",
"again",

Or realize that there are no new jokes.

That is a good one !

That way, you don't have to number the jokes.

'Faith without judgement merely degrades the spirit divine.'

j=new Array
j[0]="haha"
j[1]="next joke"
j[2]="again"
//....
j[20]="last joke"
/script

Or you could do Math.random()*3

Or better, use Math.floor(Math.random() * j.length). That way, you
don't have to


Not in the case under investigation, where there is a gap in the array !

The point was that if the literal object notation is used, there won't be a gap.

var j = ["haha", "next joke", "again", "last joke"];

Smaller, faster, easier to edit, no gaps.

I know how to display random jokes or sayings. But only if I reload
the page does the script select a new saying. How can I click on
the saying and have it load a new one in its place.


script
j=new Array
j[0]="haha"
j[1]="next joke"
j[2]="again"
//....
j[20]="last joke"
/script

div onclick="this.innerHTML=j[Math.floor(Math.random()*21)]"
Click here for jokes
/div


This did not quite work. This is just about what I wanted. I keep
geting a message that says undefined. I think that the part after
innerHTML= has to be in the script too.


It works all right, tested on IE6, but you have to fill in all 20 texts,
otherwise you get that "undefined"

Sorry. But for some reason, I could not quite get it to work. So I
messed around until I got it to work. Here is what I came up with.


<script>
j=new Array(2)
index = Math.floor(Math.random() * j.length) + 1;
</script>

<div onclick="this.innerHTML=index">Click Here</div>


Now I have another question. I just wanted to take it a step at a
time.

What I really would like to do, is to put each joke into seperate .js
files. Otherwise, since I have hundreds of them it would bog down the
page with too much data and take too long to load into the browser. I
read at www.netmechanic.com where if it takes more than 8 seconds to
load the page then most people will just get bored and go elsewhere.

I have lots of random content and I do not like it when some one has
to reload the whole page to see a different joke or whatever because
it increments the counter. So I thought it would be more convenient if
the person could just click on the joke TEXT and have it display a new
joke each time.

But not just 1 time. Over and over again until they got tired of
reading jokes.

I tried it with an iframe and then just put onclick=location.reload()
in the body tag of the html file in the iframe. That way each time I
clicked on the joke itself the iframe subpage reloaded and displayed a
new joke from the array. It worked great, except that some of the
jokes were larger than the iframe window and then I could not see the
whole thing. I placed each joke in a table, and then gave it a height
and width. But I did not know how to transfer the height and with of
the table in the iframe to the iframe height and width. You know so
that if the table with the joke became larger or smaller the iframe
would resize as needed.

So anyway, I thought there must be an easier way.

That script example I last gave you is no good. It just displays the
index number, not the joke in the array. For some reason I cannot get
it to display the joke. If I put this.innerHTML=j[1] it still says
undefined.

What script are you talking about ?
Show it again please.

1 are you using IE and what version? or something else ?

2 start debugging:

this.innerHTML="Yes"
alert(j[1])

etc.

Odd, I don't hear anybody laughing.
Some people just can't tell a joke.
