I am using the SP file attachment modal to attach files to list items and I am having an issue with trying to target the OK button click event.
I know I can use the dialog callback once it finishes, but how can I target it this at the start once the user clicks the button to upload the file?
The reason being is I have a custom loader where I want to fade the dialog-content out, fade in my loader and then when it completes in the callback, fade the loader out.
I cannot figure out how to get access to the button click event though, which is causing an issue because depending on how big the file is, it can take a minute or more to upload. In the meantime the users are sitting there with no prompts, no nothing to let them know what is going on and I get the feeling they might not wait for it to finish and just try and reload the page thinking it froze. Any help here?
