How to Get a source from an Iframe on another page and refresh it

[unitedgt]

Hello all,

I'm having trouble with this code. It works but every time I click on a link that resides on the page that loaded through the Iframe, it opens the page through the iframe, but refreshes back to the original source that loaded. Any suggestions?

function getSource()
{
ifsrc=location.search.substring(1)
idx1 = ifsrc.indexOf("a=")
anchorName = ifsrc.substring(idx1+2,ifsrc.length)
ifsrc=ifsrc.substring(6,idx1-1)
document.getElementById('maincontent').src = ifsrc + "#" + anchorName;
}

I'm calling this function through an onload in the body
