JavaScript: Change browser window status message

When we hover on some link text, the target link is shown in the status bar. How can we hide the link address in the status bar. For example, in following link:

<a href="javascript:$('#fileUpload2'开发者_运维问答).fileUploadStart()">Start Upload</a> 

---

Try this

<a onClick="javascript:$('#fileUpload2').fileUploadStart()" href="javascript:void(0)">Start Upload</a>`

Only javascript:void(0) will show up in the browser window.
