Changing Look of the Domino Upload Control (DUC) on a Domino Web Page/Form

Notes Developer Tips

The standard Domino File Upload Control (FUC) is easy to use, but not pretty to use. Below is a solution that solves the problem w/o refactoring to an XPage. There is nothing wrong with doing that; but that was not desired when the rest of the app was classic "Notes" and "web".

This reference document are the basic steps we took to update our 2008 web Send Files form for the Mindwatering web site to a more modern look still using "classic" Domino web development. JQuery and AngularJS are NOT required for this solution. JavaScript support is still required.

We have a form called Send Files | Files.
It has a WebQuerySave agent called wqsSendFiles.

The Files form has an Email field, a Comments field called Body, and the FUC control. It also has a hidden field that stores the attachment used with the JS validation to confirm that both the Email field and the FUC have been populated. The WQS agent has three purposes: to confirm the Email field and the FUC were indeed populated, to perform notification to Mindwatering staff that an upload has been received, and to move the comments, followed by the attachments into the new/permanent RTF in a field called WP_Body.

Although with positioning of a RTF field with a control, with one immediately following the other, allows for the attachments to automatically go into the Body RTF field, we didn't want this layout restriction. That is why the WQS agent moves the attachment into a new RTF field. The attachment move uses the system/OS temp folder; it could use a NotesStream but we have not bothered to rewrite that part of the WQS agent.

The DUC and the common <input type="file" multiple> can upload more than one file if the multiple attribute is added to the input/FUC. We didn't do that because we still had some IE 8 and 9 -based enterprise clients who had not updated all their employee machines to Windows 7 and 10 until 2016. So this solution does NOT support IE 8, and may not support IE 9. It is tested with IE 11, Firefox, Chrome, and Safari, all on Mac, and IE via a Windows 7 or 10 VM.

Send Files Form Updates:

1. Reduce number of File Upload Controls to just one.
The old form had 3 FUC elements, so the first thing to do was to removed the extra two. We also made some minor layout changes. Below are the Old and New layouts.
Hide details for Old Form:Old Form:
Old Form:

Hide details for New Form:New Form:
New Form:

For the File Upload Control, we the following properties set the the HTML tab:
ID: file1_1
Class: inputfile
Other: data-multiple-caption="{count} Selected" multiple

The ID file1_1, is for the label to reference its control, and for the JavaScript to get the control.
The class inputfile, is for applying CSS. We apply CSS so that the control is basically hidden, but has a 0.1 width and height for tabbing.
The data-multiple-caption="{count} Selected" is for the label to be dynamically updated by the JavaScript
The single word multiple toggles the FUC to more than one attachment.

2. Add the new label to be our new user interface to the FUC, and a div to contain the list of files selected.
For the label and for displaying the list of files selected, we used pass-thru HTML.

<label for="file1_1"><span> Select Files </span></label> *

<div id="filelist" class="filelist"></div>

The for="file1_1" makes clicking the label "button" the same as clicking the old Browse button of the control.

3. Update the JS Header and the onLoad form events with the following:

--> Add to the JS Header:
// File upload
var inputs;

// Start of form validation
function validate() {
var f = document._Files;
// check for attachment name, add to FileUploadName field if exists, if not return error
if(f.file1_1.value == ""){
msg = "No file was attached.";
alert (msg);
return false;
} else {
f.FileUploadName.value = f.file1_1.value;
// check email field populated
var emailFld = document.getElementById("Email");
if (emailFld == null) {
var emailaddr = "";
msg = "Please enter your e-mail.";
alert (msg);
return false;
} else {
var emailaddr = emailFld.value;
var estr = new String(emailaddr);
var atindex = estr.indexOf("@");
if(atindex ==-1) {
msg="Your e-mail address isn't in a valid format.";
alert (msg);
return false;
} else {
// address okay

window.status='Document Submitted Successfully';
// End of Field Validation

--> Add to the onLoad:
;( function ( document, window, index ) {
var inputs = document.querySelectorAll( '.inputfile' ); inputs, function( input )
var label = input.nextElementSibling,
labelVal = label.innerHTML;
input.addEventListener( 'change', function( e )
var fileNums = '';
var fileNms = '';
if( this.files ) {
fileNums = ( this.getAttribute( 'data-multiple-caption' ) || '' ).replace( '{count}', this.files.length );
for (var i = 0; i < this.files.length; i++ ) {
fileNms += this.files[i].name + '<br/>';
if( fileNums ) {
label.querySelector( 'span' ).innerHTML = fileNums;
document.getElementById('filelist').innerHTML = fileNms;
} else {
label.innerHTML = labelVal;
document.getElementById('filelist').innerHTML = '';
// Firefox bug fix
input.addEventListener( 'focus', function(){ input.classList.add( 'has-focus' ); });
input.addEventListener( 'blur', function(){ input.classList.remove( 'has-focus' ); });
}( document, window, 0 ));

4. The following elements remained unchanged:

- Email
Text - Editable
Default Value: ""
Input Translation: @Trim(@ThisValue);

- Body
RTF - Editable
ID: Body
Class fldBody

- FileUploadName
Text - Editable
Default Value: ""
Input Translation:
@If(@Contains(tmp; "\\"); @RightBack(tmp; "\\"); tmp)
HTML Attributes: "type=hidden"

- Send File(s) button
Name: btnSend
ID: btnSend
Common JavaScript: validate();

5. WebQuerySave agent remains unchanged:

6. The CSS is loaded from a style sheet element.

It's loaded into the header via a JS Header @DbLookup which creates the following HTML:
<link rel="stylesheet" media="" title="SendFiles" type="text/css" href="/MWTransfer.nsf/webHH/sendfiles.css">

The CSS tags are below. The File Upload Control (FUC) his hidden via the it's class ID inputfile. The label "button" is styled via its inputfile + label CSS below.

body { font-family: futura-medium, futura, helvetica, arial, sans-serif; font-size: 10pt; }

.wptitle {padding-left: 0px;}.wpbodytable {margin-top: 20px;}

.inputfile { width: 90.1px; height: 90.1px; opacity: 0; overflow: hidden; position: absolute; z-index: -1;}

.inputfile + label { font-size: 14pt; color: #000000; border: solid 1px #604578; background-color: #d0c0f9; display: inline-block; cursor: pointer; padding: 8px;}

.inputfile:focus + label { outline: 1px dotted #000; outline: -webkit-focus-ring-color auto 5px;}

.inputfile + label:hover { background-color: #604578; color: #ffffff;}

.filelist { padding: 10px 0px 10px 0px; color: #553377;}

.fldEmail {width: 95%;}

.fldBody {width: 95%;}

#btnsend { margin-top: 10px; margin-bottom: 10px; min-width: 200px; font-size: 14pt; display: inline-block; cursor: pointer; padding: 8px;}
