getting one liners randomly chosen from a set

[mikeycorn]

Real newbie web design question:

I'm working with dreamweaver 4 and I can't figure where to look in the help to find out how you set it up to where I have a group of different one-liners (a set of single lines of text) and have a different one randomly selected and displayed each time the page is hit.

Anyone?

This is one way to do it using JavaScript:


<script type="text/javascript"><!--
function randomNumber(maxValue, minValue) {
//If minValue/maxValue is missing make it/them 0/1
if (minValue == null) minValue = 0;
if (maxValue == null) maxValue = 1;

//Return the number
return (Math.round(maxValue * Math.random()) + minValue);
}
//List of all lines wanted - add your own
var oneLiner = new Array(
'Line 1',
'Line 2',
'Line 3',
'Line 4'
);
//Output the line
document.write(oneLiner[randomNumber(oneLiner.length-1)]);
document.close();
//--></script>


Just add the lines you want to be written to the array, seperated by commas, and encased in single or double quotes.

Wow! That is cool. Thanks Rick Bull. (Damn, I'm afraid that little snippet right there has me thinking it's time to move beyond the comfy confines of VB and start learning some new tricks.)

How do I get single quotes inside the single quotes???

I figured maybe the percent sign and the ascii code.

As an example, I tried 'It%39s only me.' but it didn't work.

You can either escape it with \ like so:


document.write('single quote \\'');


or use double quotes:


document.write("single quote '");

In JavaScript ' and " are completly interchangeable, except that the starting and ending sign of one particular string must be the same (you can't do "this is a string')

Awesome, thanks guys.

If you want to check out the little spice you just helped me add to my web page, check out the slogans at the bottom of the page:

www.vellosoft.com

And be sure to hit refresh a bunch of times (some of them are funnier than others.)

You think you have enough catch-phrases in there, there must be about 50 :eek:

[mikeycorn]

Actually, that nice JavaScript you provided is dipping into an array of 367 slogans I had put together for a quiz on corporate slogans. My favorite are the one's that make absolutely no sense, like "Vellosoft. The Other White Meat." or "Vellosoft. Just for the Taste of It."

:D

Ah right, it all makes sense now. :p
