Please help with IFrame callback
- by Code Sherpa
Hi - thanks for clicking.
I am trying to get status feedback using an IFrame for file uploads. I am not trying to get progress or percentages -
just when a file is done uploading and if it was a success or failure.
THE PROBLEM is that I can't seem to get the server response
to appear on the client. I have to following design:
I have an iframe on my page:
<iframe id="target_frame" src="" style="border:0px; width:0px; height:0px"></iframe>
The form tag points to it:
<form enctype="multipart/form-data" id="fileUploadForm" name="fileUploadForm" action="picupload.aspx" method="post" target="target_frame">
And the submit button starts a file upload via the iframe:
<input id="submit" type="submit" value="upload" />
In the picupload.aspx.cs file, I have a method that returns
dynamic data. I then send it to the client:
message = data;
Response.Write(String.Format("<script language='javascript' type='text/javascript'>window.parent.handleResponse('{0}');</script>", message));
On the client, I have a response handler:
function handleResponse(msg) {
document.getElementById('statusDiv').innerHTML = msg;
}
My intent is to see the msg value change for each uploaded file but I never see anything appear in statusDiv, let alone dynamically changing messages.
Can somebody please help??
