移动端 window.location.href 跳转app无效的问题

url地址是 market://details?id=com.juphoon.justalk&referrer=utm_source=newheaderen
我在网页上用a连接href="market://details?id=com.juphoon.justalk&referrer=utm_source=newheaderen"可以跳转,
但是用 window.location.href= "market://details?id=com.juphoon.justalk&referrer=utm_source=newheaderen" 则无效,
求大神解答,

附上源码

<input type="text">
<a href="market://details?id=com.juphoon.justalk&referrer=utm_source=newheaderen">测试一下</a>

<script type="text/javascript">

setTimeout(function(){
    window.location.href = "http://www.baidu.com";//可以跳转
    window.location.href = "market://details?id=com.juphoon.justalk&referrer=utm_source=newheaderen";//不会跳转
},2000)
