Running a function on another page
Hi guys, I hope you can point me in the right direction.
I would like to have a link that runs a javascript command on another page on the site. The function would be to have a div that fades in color (to guide the user to where he/she is supposed to look at
Below is the code that works if it's all on the same page.
<html>
<head>
<script type="javascript">
function colorFade(id,element,start,end,steps,speed) {
var startrgb,endrgb,er,eg,eb,step,rint,gint,bint,step;
var target = document.getElementById(id);
steps = steps || 20;
speed = speed || 20;
clearInterval(target.timer);
endrgb = colorConv(end);
er = endrgb[0];
eg = endrgb[1];
eb = endrgb[2];
if(!target.r) {
startrgb = colorConv(start);
r = startrgb[0];
g = startrgb[1];
b = startrgb[2];
target.r = r;
target.g = g;
target.b = b;
}
rint = Math.round(Math.abs(target.r-er)/steps);
gint = Math.round(Math.abs(target.g-eg)/steps);
bint = Math.round(Math.abs(target.b-eb)/steps);
if(rint == 0) { rint = 1 }
if(gint == 0) { gint = 1 }
if(bint == 0) { bint = 1 }
target.step = 1;
target.timer = setInterval( function() { animateColor(id,element,steps,er,eg,eb,rint,gint,bint) }, speed);
}
// incrementally close the gap between the two colors //
function animateColor(id,element,steps,er,eg,eb,rint,gint,bint) {
var target = document.getElementById(id);
var color;
if(target.step <= steps) {
var r = target.r;
var g = target.g;
var b = target.b;
if(r >= er) {
r = r - rint;
} else {
r = parseInt(r) + parseInt(rint);
}
if(g >= eg) {
g = g - gint;
} else {
g = parseInt(g) + parseInt(gint);
}
if(b >= eb) {
b = b - bint;
} else {
b = parseInt(b) + parseInt(bint);
}
color = 'rgb(' + r + ',' + g + ',' + b + ')';
if(element == 'background') {
target.style.backgroundColor = color;
} else if(element == 'border') {
target.style.borderColor = color;
} else {
target.style.color = color;
}
target.r = r;
target.g = g;
target.b = b;
target.step = target.step + 1;
} else {
clearInterval(target.timer);
color = 'rgb(' + er + ',' + eg + ',' + eb + ')';
if(element == 'background') {
target.style.backgroundColor = color;
} else if(element == 'border') {
target.style.borderColor = color;
} else {
target.style.color = color;
}
}
}
// convert the color to rgb from hex //
function colorConv(color) {
var rgb = [parseInt(color.substring(0,2),16),
parseInt(color.substring(2,4),16),
parseInt(color.substring(4,6),16)];
return rgb;
}
</script>
</head>
<body>
<a href="javascript:colorFade('fade1','background','D7FFCC','ffffff',100,70)">Click here to see a div fade</a>
<br><br>
<div id="fade1"> This div will fade</div>
</body>
</html>
Can someone please tell me what I need to put on the other page? Is this an onLoad issue?
Thank you for all the help!
