基于jquery的一个图片hover的插件(2)

that.cutter = function(){
var w = that.node.width() / 2;
var h = that.node.height() / 2;
that.node.hover(function(){
that.imga[0].stop().animate({
'left': '-' + w,
'top': '-' + h
}, that.speedOut, that.easeOut);
that.imga[1].stop().animate({
'right': '-' + w,
'top': '-' + h
}, that.speedOut, that.easeOut);
that.imga[2].stop().animate({
'left': '-' + w,
'bottom': '-' + h
}, that.speedOut, that.easeOut);
that.imga[3].stop().animate({
'right': '-' + w,
'bottom': '-' + h
}, that.speedOut, that.easeOut);
}, function(){
that.imga[0].stop().animate({
'left': 0,
'top': 0
}, that.speedIn, that.easeIn);
that.imga[1].stop().animate({
'right': 0,
'top': 0
}, that.speedIn, that.easeIn);
that.imga[2].stop().animate({
'left': 0,
'bottom': 0
}, that.speedIn, that.easeIn);
that.imga[3].stop().animate({
'right': 0,
'bottom': 0
}, that.speedIn, that.easeIn);
})
};

.stop()函数的作用就是如果在事件再次出发的时候，上一次的动画还在进行中的话，就终止动画，这样效果更加自然一些。that.easeIn和that.easeOut参数是用来设置动画的模式的，默认的jQuery库只有两种简单的线性库，可以下载jQuery.easing库来添加更多绚丽的效果。
这样就完成了这个插件的编写，完整的代码如下：

复制代码 代码如下:

(function($){
$.jCutter = function(node, o){
o = $.extend({
speedIn: 300,
speedOut: 300,
easeIn: '',
easeOut: ''
}, o || {});
var that = this;
that.init = function(){
that.node = $(node);
that.img = that.node.find('img');
that.speedIn = o.speedIn;
that.speedOut = o.speedOut;
that.easeIn = o.easeIn;
that.easeOut = o.easeOut;
that.generate();
that.cutter();
};
that.generate = function(){
var w = that.node.width() / 2;
var h = that.node.height() / 2;
that.imga = [];
for (var i = 0; i < 4; i++) {
that.imga[i] = document.createElement('div');
that.imga[i] = $(that.imga[i]);
that.imga[i].css({
'position': 'absolute',
'z-index': '2',
'width': w,
'height': h,
'background': 'url("' + that.img.attr("src") + '") no-repeat'
});
$(that.node).append(that.imga[i]);
}
that.imga[0].css({
'left': '0px',
'top': '0px'
});
that.imga[1].css({
'right': '0px',
'top': '0px',
'background-position': '-' + w + 'px' + ' 0px'
});
that.imga[2].css({
'left': '0px',
'bottom': '0px',
'background-position': '0px' + ' -' + h + 'px'
});
that.imga[3].css({
'right': '0px',
'bottom': '0px',
'background-position': '-' + w + 'px ' + '-' + h + 'px'
});
that.img.remove();
};
that.cutter = function(){
var w = that.node.width() / 2;
var h = that.node.height() / 2;
that.node.hover(function(){
that.imga[0].stop().animate({
'left': '-' + w,
'top': '-' + h
}, that.speedOut, that.easeOut);
that.imga[1].stop().animate({
'right': '-' + w,
'top': '-' + h
}, that.speedOut, that.easeOut);
that.imga[2].stop().animate({
'left': '-' + w,
'bottom': '-' + h
}, that.speedOut, that.easeOut);
that.imga[3].stop().animate({
'right': '-' + w,
'bottom': '-' + h
}, that.speedOut, that.easeOut);
}, function(){
that.imga[0].stop().animate({
'left': 0,
'top': 0
}, that.speedIn, that.easeIn);
that.imga[1].stop().animate({
'right': 0,
'top': 0
}, that.speedIn, that.easeIn);
that.imga[2].stop().animate({
'left': 0,
'bottom': 0
}, that.speedIn, that.easeIn);
that.imga[3].stop().animate({
'right': 0,
'bottom': 0
}, that.speedIn, that.easeIn);
})
};
that.init();
};
$.fn.jCutter = function(o){
return this.each(function(i){
$.jCutter(this,o);
});
};
})(jQuery);

很简单有趣的效果，逻辑很清楚，代码也简单，是练手的好东东。
