Ctr+s event on clicking a hyperlink

I have a hyperlink, when i c开发者_StackOverflow社区lick this link Ctr+s event should be fired which results in prompting to save the webpage. How can i call Ctr+s event when clicking a link I needs this in javascript or jquery

add onClick event same as Ctrl+S. Don't return false in onClick

I believe this works in ie.

<a href="javascript:void(0);"  onclick="document.execCommand('SaveAs');"
 >Save this page</a>
