自己用jQuery写了一个图片的马赛克消失效果_jquery

其中的一个效果:

html代码:

单击图片,产生效果

插件代码:

; (function ($) {
var defaults = {
ani: 4, //动画效果.1.马赛克向中间聚拢,2.马赛克左上角聚拢,3.马赛克拉扯消失,4.原地缩小
delay: 3000, //动画执行时间
url:"0",//图片路径
count: [20, 20]//马赛克水平数量,竖直方向数量;数量不能过多,否则计算量太大,计算机执行不了,导致浏览器卡死
}
$.fn.gysMaSaiKe = function (opt) {
opt = $.extend({}, defaults, opt);
if(opt.url=="0"){alert("没有填写图片路径参数");return;}
var obj = $(this);
if (obj.css("position") == "static") obj.css({ "position": "relative" });
obj.css("overflow","hidden");
var objWidth = obj.width();
var objHeight = obj.height();
(function (count,url, obj) {
var littleBoxWidth = Math.floor(objWidth / count[0]);
var littleBoxHeight = Math.floor(objHeight / count[1]);
var html = "";
var littleBoxLeft = littleBoxWidth * (-1), littleBoxTop = littleBoxHeight * (-1);

for (var i = 0; i littleBoxTop += littleBoxHeight;
for (var j = 0; j littleBoxLeft += littleBoxWidth;
html += "";
}
littleBoxLeft = littleBoxWidth * (-1);
}
obj.html(html);
})(opt.count,opt.url,obj);

var animation = function (ani, delay, objs) {
var res = function () { }
if (ani == 1) {//马赛克向中间聚拢
res = function () {
objs.animate({ top: objHeight / 2, left: objWidth / 2, opacity: 0 }, delay);
setTimeout(function(){obj.html("");},delay);
}
}
else if (ani == 2) {//碎片向左上角聚拢消失
res = function () {
objs.animate({ left: 0, top: 0, opacity: 0 }, delay); setTimeout(function () { obj.html(""); }, delay);
}
}
else if (ani == 3) {//拉扯消失
res = function () {
objs.filter(":even").animate({top:-100,left:-100},delay);
objs.filter(":odd").animate({ top: -100, left:900}, delay); setTimeout(function(){obj.html("");},delay);
}
}
else if (ani == 4) {//
res = function () { objs.animate({ height: 0, width: 0 }, delay);setTimeout(function(){obj.html("");},delay); }
}
else {
res = function () { objs.animate({ height: 0, width: 0 }, delay);setTimeout(function(){obj.html("");},delay); }
}
return res;
} (opt.ani, opt.delay, obj.children());

obj.on("click", "span", animation);
}
})(jQuery);

css代码:

.box { width: 1000px; height:600px;}

插件的调用:

$(function () {
$(".box").gysMaSaiKe({
count: [10, 15], //马赛克水平数量,竖直方向数量;数量不能过多,否则计算量太大,计算机执行不了,导致浏览器卡死
ani: 4, //动画效果.1.马赛克向中间聚拢,2.马赛克左上角聚拢,3.马赛克拉扯消失,4.原地缩小
delay: 5000, //动画执行时间
url: "1.jpg" //图片路径
});
});
