复制代码 代码如下:
<script type="text/javascript">
(function($){
var ele_fix = $("#div_right"); //浮动窗口
var _main = $(".main"); //浮动区域
var ele_offset_top = ele_fix.offset().top; //浮动区域高度
$(window).scroll(function(){
var scro_top = $(this).scrollTop(); //当前高度
var fix_foot_pos = parseInt(ele_fix.height())+parseInt(scro_top)-10; //浮动框最底部到最顶部高度
var mainpos = parseInt(_main.offset().top)+parseInt(_main.height());
if(scro_top <= ele_offset_top&&fix_foot_pos<mainpos){
ele_fix.css({position: "static", top: -10});
}else if(scro_top>ele_offset_top&&fix_foot_pos<mainpos){
ele_fix.css({position: "fixed", top: -10});
}else if(scro_top>ele_offset_top&&fix_foot_pos>mainpos){
var posi = mainpos-fix_foot_pos-10;
ele_fix.css({position: "fixed", top: posi});
}
});
/*
//方案二
$(window).bind("scroll",function() {
var temp = '1165';
//判断往下滚
if ($(document).scrollTop() > temp) { //如果大于这个高度，就置顶

}
if ($(document).scrollTop() <= temp) { //如果小于这个高度，则恢复原来状态
flag = true;
$('#div_right').css('position','');
}
});
*/
})(jQuery);
