i need to animate in a similar style the 'div id="green"' to a green colour directly after it for a similar length of time. This is where I need help, i'm stuck. thanks
this is the code i have already for the animation in javascript.
lerp = function(a, b, u) {
return (1 - u) * a + u * b;
};
fade = function(element, property, start, end, duration) {
var interval = 10;
var steps = duration / interval;
var step_u = 1.0 / steps;
var u = 0.0;
var theInterval = setInterval(function() {
if (u >= 1.0) {
clearInterval(theInterval)
}
var r = parseInt(lerp(start.r, end.r, u));
var g = parseInt(lerp(start.g, end.g, u));
var b = parseInt(lerp(start.b, end.b, u));
var colorname = 'rgb(' + r + ',' + g + ',' + b + ')';
el.style.setProperty(property, colorname);
u += step_u;
}, interval);
};
el = document.getElementById('yellow');
property = 'background-color';
startColor = {
r: 255,
g: 255,
b: 255,
};
endColor = {
r: 255,
g: 255,
b: 0
};
fade(el, 'background-color', startColor, endColor, 10);
setTimeout(function() {
fade(el, 'background-color', endColor, startColor, 10);
}, 1000);
You can do following way.
el = document.getElementById('yellow');
el1 = document.getElementById('green');
setTimeout(function() {
fade(el, 'background-color', endColor, startColor, 10);
fade(el1, 'background-color', greeColor, startColor, 2000);
}, 1000);
And change in function
el.style.setProperty(property, colorname);
To
element.style.setProperty(property, colorname);
