How do I make random sentences appear when page refreshes

**thinandpale** · 08-22-2006, 09:24 AM

I'm not sure if I need php for this to work, but I've seen it done with seperate JS files in the same directory.

I've been looking at other sites to see how they do it, but I can never view the changing script! What do I need to put on the page to make the changing script appear on the page?

Put that into the HEAD section of your page:

Code:

<script type="text/javascript">
var sentences = new Array(
	"Put your sentences here.",
	"Quoted and comma delimited.",
	"Third sentence.",
	"Fourth sentence.",
	"And so on...",
	"<em>HTML tags may be used</em>",
	"Use <br /> for line breaks.",
	"NO COMMA AFTER THE LAST ONE!!!"
);
</script>

And that, where you want the sentences to appear:

Code:

<script type="text/javascript">
document.write(sentences[Math.floor(Math.random()*sentences.length)]);
</script>

Whoops, sorry, my bad, there was a typo in the code

try it again, it works now.

**thinandpale** · 08-22-2006, 11:21 AM

Yeah, that was it......... that worked!

Thank you very much. I've been searching the whole web for the last 20 hours trying to figure this out. I read pages after pages of .js and .php and other message boards weren't able to help.

Thanks for helping me.

I was trying to use the Array method, but this works.

Is there a way for me to use mp3 embed tags instead of sentences ?

or do I need to make a seperate page listing the mp3 files and then if so what do I do to get those mp3 songs to play at random when the page refreshes.

**thinandpale** · 08-22-2006, 11:35 AM

I made a sample page for both scripts. They both work.

Is there a way for me to use mp3 files ?

**blm126** · 08-22-2006, 12:39 PM

Where ever you put the string to display put the HTML for your mp3.

**thinandpale** · 08-23-2006, 02:06 AM

I just figured it out....

I needed to put \ infront of " in the embed so it could read it

Thought that I would just throw in here that my version, because it uses cookies, is much less likely to ever randomly repeat. Cookies would have to be disabled for that to happen.
