Is there a way to launch an ajax request in a distinct frame?

So, I've come across this code snippet:

<script language="javascript" type="text/javascript">
<!--

function loadContent(page) {

    var request = false;

    try {
        request = new XMLHttpRequest();
    } catch (e) {
        try{
            request = new ActiveXObject("Msxml2.XMLHTTP");
        } catch (e) {
            try{
                request = new ActiveXObject("Microsoft.XMLHTTP");
            } catch (e) {
            alert("Unable to perform the action.");
            return false;
            }
        }
    }

    request.onreadystatechange = function() {
        if(request.readyState == 4) {
            if(request.status == 200) {    
                document.getElementById('content').innerHTML = request.responseText;
            }
        }
    }

    request.open("GET", "include.php?page=" + page, true);
    request.send(null);
}

//-->
</script>

And then calling it like this:

<a onclick="javascript:loadPage('red_the_clown')"><li>Red</li></a>
<div id="content"><?php include('index2.php'); ?></div>

I've been struggling to figure out how to specifically target a different frame instead of the current one. For example, the #content div will be in _main, but it's being requested from another frame.

Any suggestions or solutions would be greatly appreciated!

Cheers,

Ryan

Answer №1

Are you trying to retrieve the document from within a frame?

The term top refers to the highest level frame, while parent refers to one level above.

To make your JavaScript code work properly, you may only need to make a small adjustment:

top.document.getElementById('content').innerHTML = request.responseText;

Keep in mind that both frames must originate from the same domain in order to avoid restrictions imposed by browser security measures.

Answer №2

Do you currently possess an iframe identified as "_main"?

What are your thoughts on this approach?

If you have an iframe with the id "_main", you can use the following code to update its content:
window.frames["_main"].document.getElementById("content").innerHTML = request.responseText;
