javascript and _IEGetObjById

[Jury]

A search of a web page can retrieve 1 to 20 (or more) links split into 20 per page I can go on to the second page by using:

If $x = 20 Then
Sleep(2000) ;two seconds
$oNext = _IEGetObjById($oIE, "pager1")
_IEAction($oNext, "click")
_IELoadWait($oIE)

where $x is the count of links on the previous page but how do I get to the next page given the next page object is in javascript as seen here:

<a id="pager1" href="javascript:__doPostBack('pager1','2')">2</a> -

<a id="pager1" href="javascript:__doPostBack('pager1','3')">3</a> -

<a id="pager1" href="javascript:__doPostBack('pager1','4')">4</a> -

<a id="pager1" href="javascript:__doPostBack('pager1','5')">5</a>

<a id="pager1" href="javascript:__doPostBack('pager1','2')">Next ></a>

is there a way of sending the doPostBack('pager1','3') information? BTW I just thought (I.m not at my own PC) can I get IEGetObjById by index so somthing like that?

Looks like this isn't doable within the confines of Autoit - below is what I've ended up with. I'm curious though if the javascript had been given different id like pager1, pager2, pager3... or been given name="pager1" so I could have used index would it have worked? Oh and I know this only works on some PC & IE combinations - I only have the one PC.
