今天要出个鼠标滚动放大缩小图片的功能，看似很简单，从网上一搜，出现的都是onmousewheel的例子，全部只支持IE浏览器，结果查出火狐有对应的DOMMouseScroll来处理这个功能，代码如下,并加上注意的注释项：
$(function(){
$(".body img").each(function(){
if($.browser.msie){
$(this).bind("mousewheel",function(e){
var e=e||event,v=e.wheelDelta||e.detail;
if(v>0)
resizeImg(this,false);//放大图片呗
else
resizeImg(this,true);//缩小图片喽
window.event.returnValue = false;//去掉浏览器默认滚动事件
//e.stopPropagation();
return false;
})
}else{
$(this).bind("DOMMouseScroll",function(event){
if(event.detailresizeImg(this,false);
else
resizeImg(this,true);
event.preventDefault()//去掉浏览器默认滚动事件
//event.stopPropagation(); })
}
});
function resizeImg(node,isSmall){
if(!isSmall){
$(node).height($(node).height()*1.2);
}else
{
$(node).height($(node).height()*0.8);
}
}
});
