xmlhttp request to parent page and self close

[travisbrown]

I'm refreshing an object in a parent window when closing a popup. I thought i could just use self.close(), but it messes stuff up.

FF js console gives me "http is not defined" on this line in the second function: if ( http.readyState == 4 ) {

Refreshes properly when I take self.close out. Any hints?

<a href="javascript:sndParentReq('call_index.asp?key=<% = LEFT(song_title,1) %>','songlist');self.close();" ><img src="_images/exit.gif" class="savebutton" /></a>

var http = createRequestObject();

function sndReq(page,insert) {
    http.open( 'get', page );
    http.onreadystatechange = function(){
		 if ( http.readyState == 4 ) {
        var response = http.responseText;
        document.getElementById(insert).innerHTML = response;
		}	
	};
    http.send(null);
}

function sndParentReq(page,insert) {
    http.open( 'get', page );
    http.onreadystatechange = function(){
		 if ( http.readyState == 4 ) {
        var response = http.responseText;
        opener.document.getElementById(insert).innerHTML = response;
		}	
	};
    http.send(null);
}

Presumably if you close the popup, the function assigned to onreadystatechange is removed, and so would no longer work.

Oh, I see. I thought once it was changed, it was changed since I could close the page manually.

Any ideas on a process so I can 1. show the changes in the parent page without doing a complete opener refresh 2. close the popup?

The functions are in an outfile. Can an event trigger a function on the parent page? Sort of wrap the function in another so it is the parent calling the httpxml, not the popup?

Yes - you should be able to use a "send" function in the opener instead of the popup with no problem. Use "opener.sndParentReq" instead of "sndParentReq" (assuming you move the functions to the opener, of course).

Hope this helps,

Hmm... look like there is anything wrong with this? Still can't get it to close the popup. sndReq is firing okay, but window won't close.

<script type="text/javascript">
opener.sndReq('call_profiles.asp?str=help','autocomplete_lanid');
opener.sndReq('call_profile.asp?lanid=help','profile');
opener.document.getElementById('txt_lanid').value = 'help';
self.close;
</script>

~bump~

Maybe I should ask first: is it possible to self.close a window after calling a opener function?

I refer only to the script in the first post.

[1] Make out a function foldup() say in the popup page. (I assume http is of scope global.)
[tt]
function foldup() {
if (http && (http.readyState==4)) {
setTimeout("window.close()",100);
} else {
setTimeout("foldup()",100);
}
}
[/tt]
[2] Change the anchor element to calling it.
[tt]
<a href="javascript:sndParentReq('call_index.asp?key=<% = LEFT(song_title,1) %>','songlist');[blue]foldup()[/blue]" ><img src="_images/exit.gif" class="savebutton" /></a>
[/tt]
I assume proper functioning of the rest.
