用document.location.replace('http://ask.csdn.net/questions/241212')来转向，阻止默认的连接href跳转
<a href="http://ask.csdn.net/questions/241212">http://ask.csdn.net/questions/241212</a><br>
<a href="http://ask.csdn.net/questions/240607">http://ask.csdn.net/questions/240607</a>
<script src="http://ajax.aspnetcdn.com/ajax/jQuery/jquery-1.7.2.min.js"></script>
<script>
$('a').click(function(){
document.location.replace(this.href);
return false;
});
</script>
a标签当然会跳转啦，你用ajax请求就不会跳转页面啦。改成如下
<a href="javascript:login()" target="_parent"">
然后在javascript用ajax请求实现login退出的方法。就能停留在原来的页面啦。
