Limiting size of files a user can upload.
I want to limit the size of files my users can upload to an app? is there a native way to do this? and is there a way to retrieve the file size for existing files?
Forum Discussion
It pleases me no end to see people using JavaScript with QuickBase!
This code will immediately (no need to wait till Save button is clicked) check the file size of a selected file and remove the file from the input if it is too large.

Notes:
(1) For security reasons, you can only set the value of a file input to an empty string (essentially removing the selected file).
(2) The code uses backticks to do strinng interpolation.
(3) My code should of course be placed wthin the normal IOL module decoding logic._

$("#_fid_6").on("change", function(e) {
var maxSize = 1000;
var data = e.originalEvent.target.files[0];
if (data.size > maxSize) {
alert('Your file size is ${data.size}. Please select a smaller file.');
this.value = "";
}

- Reviving this thread. Is there a way to use script to simply put the file size into a field? I just need the file size there to then check a couple things using formulas/dynamic rules. I believe these solutions give alerts, and I don't know syntax to set a field to the size.
