【指教】javascript实现点击图片互斥
目前我需要做5个图片，当然。这个五个图片默认是a.gif
当点击其中一个时，图片换为b.gif,再点击此图片时换为a.gif;
其实就是这几个图片是互斥的关系。我做了一个。不过。不好用。
希望那位大侠帮忙一下

var pic1= "a.gif ";
var pic2= "b.gif ";
function changeImg(obj){
var tr=obj.parentNode;
if(tr.focusImg)tr.focusImg.src=pic1;
var img=obj.getElementsByTagName( "img ")[0];
img.src=pic2;
tr.focusImg=img;
}
