html+css+js粘土动画Doodle特效
1、准备好需要用到的图标。
2、新建html文档。
3、书写hmtl代码。
<div style="width:135px;height:156px;background:url(images/6_gumby11-initial-sprite.png) 0 0;" id="Div1"></div>
<div style="left:138px;top:40px;width:65px;height:102px;background:url(images/6_gumby11-initial-sprite.png) -270px 0;" id="Div2"></div>
<div style="left:196px;top:14px;width:67px;height:144px;background:url(images/6_gumby11-initial-sprite.png) -400px 0;z-index:90;" id="Div3"></div>
<div style="left:246px;top:-6px;width:98px;height:156px;background:url(images/6_gumby11-initial-sprite.png) -682px 0;" id="Div4"></div>
<div style="left:323px;top:50px;width:75px;height:108px;background:url(images/6_gumby11-initial-sprite.png) -534px 0;" id="Div5"></div>
4、书写css代码。
<style>
div{position:absolute;}
</style>
5、书写js代码。
<script language="javascript" >
window.onload = function () {
new animation({ element: "Div1", url: 'images/15_gumby11-blockheads.jpg', hover: function () { this.element.style.backgroundPositionX = '-135px'; }, blur: function () { this.element.style.backgroundPositionX = '0'; } });
new animation({ element: "Div2", url: 'images/16_gumby11-prickle.jpg', hover: function () { this.element.style.backgroundPositionX = '-335px'; }, blur: function () { this.element.style.backgroundPositionX = '-270px'; } });
new animation({ element: "Div3", url: 'images/17_gumby11-goo.png', hover: function () { this.element.style.backgroundPositionX = '-467px'; }, blur: function () { this.element.style.backgroundPositionX = '-400px'; } });
new animation({ element: "Div4", url: 'images/10_gumby11-gumby.jpg', hover: function () { this.element.style.backgroundPositionX = '-780px'; }, blur: function () { this.element.style.backgroundPositionX = '-682px'; } });
new animation({ element: "Div5", url: 'images/18_gumby11-pokey.png', hover: function () { this.element.style.backgroundPositionX = '-609px'; }, blur: function () { this.element.style.backgroundPositionX = '-534px'; } });
};
</script>
6、书写animationjs代码
<script>
function animation(options) {
var defaultOptions = { element: "", url: "", speed: 11, hover: function () { }, blur: function () { } };
this.init(options, defaultOptions);
};
animation.prototype = {
init: function (o1, o2) {
var me = this;
for (var p in o2) {
me[p] = o1[p] || o2[p];
}
me.element = document.getElementById(me.element);
me.delay = 1000 / me.speed;
me.step = 0;
me.defaultBackground = me.element.style.background;
me.defalutUrl = me.element.style.backgroundImage;
me.url = me.url || me.defalutUrl;
me.width = me.element.clientWidth;
me.height = me.element.clientHeight;
var img = new Image();
img.onload = function () {
me.cols = parseInt(img.width / me.width);
me.rows = parseInt(img.height / me.height);
me.frames = me.cols * me.rows;
me.element.onclick = function () {
me.play();
};
me.element.onmouseover = function () {
me.onhover();
};
me.element.onmouseout = function () {
me.onblur();
};
};
img.src = me.url;
}
, play: function () {
if (this.playing) {
return;
}
this.playing = true;
this.next();
},
onhover: function () {
if (!this.playing) {
this.hover();
}
},
onblur: function () {
if (!this.playing) {
this.blur();
}
},
next: function () {
var me = this;
me.step++;
if (me.step > me.frames) {
me.stop();
return;
}
var x = me.step % me.cols;
var y = parseInt(me.step / me.rows);
if (me.step % me.rows > 0) {
y++;
}
var position = "-" + (x - 1) * me.width + "px -" + (y - 1) * me.height + "px";
me.element.style.background = "url(" + me.url + ") " + position;
setTimeout(function () { me.next(); }, me.delay);
},
stop: function () {
var me = this;
me.step = 0;
me.playing = false;
me.element.style.background = me.defaultBackground;
}
};
</script>
7、代码整体结构。
8、查看效果。
