看不明白的小白 求助 解析下这段签到的函数
var ad_left = $("#ad_left");if (ad_left.length > 0) {
var ie6 = bbeng.(),
position = bbeng.() ? "absolute" : "fixed";
ad_left.css({
"position": position,
'top': bbeng.() - 130
});
ad_left.live('click', function () {
$(window).scrollTop(0);
return false;
});
$(window).resize(function () {
var scrollTop = 0;
if (ie6) {
scrollTop = bbeng.();
}
ad_left.css('top', scrollTop + bbeng.() - 130);
});
$(window).scroll(function () {
var ad_left = $("#ad_left");
var scrollTop = bbeng.();
if (ad_left.length > 0) {
var displayType = ad_left.css("display");
if (ie6) {
ad_left.css('top', scrollTop + bbeng.() - 130);
}
}
});
}
});
//签到函数
