首先,我们要判断鼠标移入对象的方向:JS代码:
;(function($){
$.fn.extend({
dirMove:function(){
var $outer=this;
var $mask=this.find("#mask");
var disL = $outer.offset().left;
var disT = $outer.offset().top;
var disR = disL + $outer.outerWidth();
var disB = disT + $outer.outerHeight();
$outer.hover(function(e){
Confirmdir(e);
},function(e){
Confirmdir(e);
});
function Confirmdir(e){ //确定具体鼠标移入对象的方向
var dirL = Math.abs(e.pageX - disL);
var dirT = Math.abs(e.pageY - disT);
var dirR = Math.abs(e.pageX - disR);
var dirB = Math.abs(e.pageY - disB);
var dir = Math.min(dirL,dirT,dirR,dirB);//取得最小值
if(e.type=="mouseenter"){
switch(dir){
case dirL:
mouseIn("left");
break;
case dirT:
mouseIn("top");
break;
case dirR:
mouseIn("right");
break;
case dirB:
mouseIn("bottom");
break;
}
}else{
switch(dir){
case dirL:
mouseOut("left");
break;
case dirT:
mouseOut("top");
break;
case dirR:
mouseOut("right");
break;
case dirB:
mouseOut("bottom");
break;
}
}
}
function mouseIn(dir){
switch(dir){
case "left":
$mask.css({"left":-$outer.outerWidth(),"top":0}).show().stop(true,true).animate({"left":0});
break;
case "top":
$mask.css({"left":0,"top":-$outer.outerHeight}).show().stop(true,true).animate({"top":0});
break;
case "right":
$mask.css({"left":$outer.outerWidth(),"top":0}).show().stop(true,true).animate({"left":0});
break;
case "bottom":
$mask.css({"left":0,"top":$outer.outerHeight}).show().stop(true,true).animate({"top":0});
break;
}
}
function mouseOut(dir){
switch(dir){
case "left":
$mask.stop(true,true).animate({"left":-$outer.outerWidth()});
break;
case "top":
$mask.stop(true,true).animate({"top":-$outer.outerHeight()});
break;
case "right":
$mask.stop(true,true).animate({"left":$outer.outerWidth()});
break;
case "bottom":
$mask.stop(true,true).animate({"top":$outer.outerHeight()});
break;
}
}
}
})
})(jQuery);
HTML代码:
$(".outer").each(function(){
$(this).dirMove();
})
