小弟我现在想把JQ代码中的图片路径变成一个变量，原理就是分别改变路径的后缀，图片全部都是同名不同后缀，望大虾们帮忙，给分多多！
[解决办法]
$('a.face').hover(function(){
this.src=this.src.replace("jpg","gif");
},function(){
this.src=this.src.replace("gif","jpg");
});

这里用正则替换一下后缀就可以实现了
$('a.face').hover(function(){
$(this).find("img.face").attr("src", function(index, attr){
return attr.replace(/jpg$/i,"gif");
});
},function(){
$(this).find("img.face").attr("src", function(index, attr){
return attr.replace(/gif$/i,"jpg");
});
});
