To prevent intra-screen jumps

I have a link on click of which I need a new pop-up window and that pop-up window should stay in the
same place and shouldn't jump to the top of the screen.

<a href="#abc" class="actionButtonDis" onClick="clicked('ABCTable',this);window.open('searchABCName.do?param=contact','searchContact','resizable=1,width=710,height=625,status=1,scrollbars=1');" >lt;/a>


For this requirement href="#" is the one that we usually give to enable a link on screen. To get the pop-up to stay in the same location and not jump to the top of the screen we need to add junk alphabets besides the #.
