我要评论jquery中给animation加更多的运作效果实例。
. 代码如下:
//animation
jquery.extend({
easing:
{ // ******* back
backeasein: function (p, n, firstnum, diff) {
var c = firstnum + diff;
var s = 1.70158; // default overshoot value, can be adjusted to suit
return c * (p /= 1) * p * ((s + 1) * p - s) + firstnum;
},
backeaseout: function (p, n, firstnum, diff) {
var c = firstnum + diff;
var s = 1.70158; // default overshoot value, can be adjusted to suit
return c * ((p = p / 1 - 1) * p * ((s + 1) * p + s) + 1) + firstnum;
},
backeaseinout: function (p, n, firstnum, diff) {
var c = firstnum + diff;
var s = 1.70158; // default overshoot value, can be adjusted to suit
if ((p /= 0.5) < 1)
return c / 2 * (p * p * (((s *= (1.525)) + 1) * p - s)) + firstnum;
else
return c / 2 * ((p -= 2) * p * (((s *= (1.525)) + 1) * p + s) + 2) + firstnum;
},
// ******* bounce
bounceeasein: function (p, n, firstnum, diff) {
var c = firstnum + diff;
var inv = this.bounceeaseout(1 - p, 1, 0, diff);
return c - inv + firstnum;
},
bounceeaseout: function (p, n, firstnum, diff) {
var c = firstnum + diff;
if (p < (1 / 2.75)) {
return c * (7.5625 * p * p) + firstnum;

return c * (7.5625 * (p -= (1.5 / 2.75)) * p + .75) + firstnum;
}
else if (p < (2.5 / 2.75)) {

调用:
. 代码如下:
$("#p").animate({
left: v
}, 1000, "circeaseout");
