在之前的js广告代码中，介绍了不少带关闭按钮的对联广告代码，比如：
今天，为大家带来的这个js对联广告代码，点击关闭按钮仅是实现缩小显示，并不关闭。
效果图，如下：
用法简介：
js对联广告点击关闭按钮缩小显示
纯js实现的对联广告代码，鼠标点击缩小层并简陋显示跟随滚动条浮动
原理非常简单js实现显示和隐藏层。
重点代码：
清空div隐藏样式为空，兼容火狐和谷歌浏览器。
function bar1190_show(){
document.getElementById('Bar1190_big').style.display='';
document.getElementById('Bar1190_small').style.display='none';
}
function bar1190_hidden(){
document.getElementById('Bar1190_big').style.display='none';
document.getElementById('Bar1190_small').style.display='';
}
var autohide1190 = setTimeout("bar1190_hidden()",5000);
function bar11901_show(){
document.getElementById('Bar11901_big').style.display='';
document.getElementById('Bar11901_small').style.display='none';
}
function bar11901_hidden(){
document.getElementById('Bar11901_big').style.display='none';
document.getElementById('Bar11901_small').style.display='';
}
var autohide11901 = setTimeout("bar11901_hidden()",5000)
