[RESOLVED] Ajax upload confusion

$

Ok - I've got this HTML - and it's working - dumping the return results into target="upload_target". Originally it was causing my page to reload - or dump into a new tab of the browser - until I found the TARGET setting.

Code:

<form id="upload" action="Upload.ashx" method="post" enctype="multipart/form-data" target="upload_target">
    <div>
        <label>
            <input type="file" name="file" multiple>
        </label>
        <br /><br />
        <button type="submit" class="acs-upload-button ui-button ui-widget ui-state-highlight ui-corner-all ui-button-text-icon-acs-use ui-button-text-icon-primary" role="button" aria-disabled="false">Upload</button>
    </div>
    <iframe id="upload_targe" name="upload_target"></iframe>
</form>

I'm trying to switch it to this JavaScript.

Code:

        function initFileUploader(strId) {
            $("form").on("click", "button[type=submit]", function (evt) {
                $.ajax("Upload.ashx", {
                    files: $(this).parent().find(":file"),
                    iframe: true
                }).complete(function(data) {
                    var returnObj = $.parseJSON(data.responseText);
                    var updArr = returnObj.update || [];
                    var strData = "";
                    var wesAWC = [];
                    for (var i = 0; i < updArr.length; i = i + 2) {
                        strData = updArr[i + 1];
                        wesAWC = $("#" + strId + " .awc-" + updArr[i]).not(".acs-edit-view-hidden");
                        p_fillField(wesAWC, strData, strId, updArr[i], false);
                    }
                    if (returnObj.ok) {
                        errorMessage("Upload Complete", returnObj.message);
                    } else {
                        errorMessage("Upload DID NOT Complete", returnObj.message);
                    }
                });
            });
        }

This function does work - properly processing the return results instead of dumping them into a single target. Problem is that this function tries to reload the page.

I can't even find jQuery docs that talk about the FILES: and IFRAME: options.

Very confused here...
