Hello guys,
I'm dealing with this situation :
- I have a color animation script which targets by id (it's not JQuery but pure javascript)
- then I have a dynamic list without ids : 'ul' somePHP throwing list items '/ul'
- and finally I have JQuery itself (which I'll use to add several ids on the fly to the list items: but I still don't know how)
I've realised that I couldn't add, with JQuery, single classes to the list items, as the color plugin only searches by id (it uses getElementById, which have no parallel with classes).
I must exclude so the addClass JQ function, which would be easy enough to put at work.
The script only would work if I could insert ids in the list, 5 well-defined ids, and give later some instructions in the externalised color plugin to affect them :
<ul>
<li><a href="" id="ontheflyone">pulled from the DB</a></li>
<li><a href="" id="ontheflytwo">pulled from the DB</a></li>
<li><a href="" id="ontheflythree">pulled from the DB</a></li>
<li><a href="" id="ontheflyfour">pulled from the DB</a></li>
<li><a href="" id="ontheflyfive">pulled from the DB</a></li>
</ul>
Then, the instructions :
document.getElementById(’id’).onmouseover = function() { 'ontheflyone','text','$color1' };
document.getElementById(’id’).onmouseout = function() { 'ontheflyone','text','$color2'};
document.getElementById(’id’).onmouseover = function() { 'ontheflytwo','text','$color1' };
document.getElementById(’id’).onmouseout = function() { 'ontheflytwo','text','$color2'};
etc.
I could change the plugin's javascript itself, but I thought it would be easier using JQuery to add, in some way, ids in my html.
The color plugin is an awesome piece of code written by Michael Leigeber I reproduce as follows :
// main function to process the fade request //
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;
}
So, a million thanks if someone can tell me how to add those ids on the fly, or, maybe, how to change the javascript to target classes,
Many thanks,
Jan
