Question

fading text, delay and change text

Asked by: VirusMinus

I have a script that fades text which works in IE and Firefox by changing the opacity of an element.

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">

<html>
<head>
     <title>Fade Text</title>
     <style type="text/css">
     </style>
</head>

<body>
<table id="blah"><tr><td>How do i make meat gravy? does anyone have a nice recipie?? </td></tr></table>

<script>
var tme=25
var d=1
var fde=1
var max=100
var min=10
var opac=max

function fade(){
if(d==1){opac+=fde}else{opac-=fde}
if(opac>max || opac<min){if(d==0){d=1}else{d=0}}
document.getElementById("blah").style.filter = "alpha(opacity="+opac+")";
document.getElementById("blah").style.opacity = (opac / 100);

setTimeout('fade()', tme)}
fade()
</script>


</body>
</html>

What I'd like to add to this function is:
1. Pass an array of 5 or more strings (which can contain quotes, semicolons etc.), that it will cycle through on each fade. i.e fade in 1st string and fade out, fade in 2nd string and fade out and so on, and then after the last one, start again at the first.
2. get the text string to stay completely visible for a fixed duration, lets say 10 seconds (so it can be read), before it starts the next fade sequence.
3. in IE the text is funny.. a bit bold. can that be fixed? i tried changing the color of the text via CSS and it appears to have a black outline...

only one thing, why is text chunky and bold in IE? any way to fix that?

 

by: pD_EOPosted on 2007-02-04 at 15:16:10ID: 18464814

I don't get that problem in IE 7, but I have heard other people getting it, so I just made the font bold.  Am not entirely sure why it does it.

 

by: VirusMinusPosted on 2007-02-16 at 23:08:07ID: 18554240

I found out how to fix the bold text for IE.

the containing element must have a background set. if not the text is bold.

 

by: VirusMinusPosted on 2007-02-16 at 23:21:53ID: 18554263

so <table id="blah" style="background:#fff"> fixes it.
