IE6中链接A的href为javascript协议时不在当前页面跳转

<p><a href="javascript:;" onclick="jumpSina()">Sina</a></p> 
<p><a href="javascript:void 0;" onclick="jumpSohu()">Sohu</a></p> 
<script> 
function jumpSina() { 
location.href = 'http://www.sina.com.cn' 
} 
function jumpSohu() { 
location.href = 'http://www.sohu.com' 
} 
</script> 
 
IE6中点击链接无法跳转，其它浏览器都可以。解决方法是改成锚点， 
 代码如下:

<p><a href="###" onclick="jumpSina()">Sina</a></p> 
<p><a href="#none" onclick="jumpSohu()">Sohu</a></p> 
<script> 
function jumpSina() { 
location.href = 'http://www.sina.com.cn' 
} 
function jumpSohu() { 
location.href = 'http://www.sohu.com' 
} 
</script> 
 
如果把跳转方式改为window.open，则IE6下没有问题，如下 
 代码如下:

<p><a href="javascript:;" onclick="jumpSina()">Sina</a></p> 
<script> 
function jumpSina() { 
window.open( 'http://www.sina.com.cn') 
} 
</script>
