    <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
    <html xmlns="http://www.w3.org/1999/xhtml">
    <head>
    </head>
    <body><script type="text/javascript">
    var bb=function(){
        document.onmouseup = function(){ alert(1); };
    }
    </script>
    <div style="width:100px;height:100px;background-color:#000000;" onmousedown="bb()"> </div>
    <div style="width:100px;height:100px;background-color:#FF0000;" onmousedown="bb()">123</div></body>
    </html>或者看这个测试吧
    当点住下面的div不放，并拖到浏览器外再放开会触发onmouseup
    但上面的div就会没有反应
