How to change a value of a form field in Form Blocks (React version)

Custom Coding

Form blocks are listening to a special event called update-fields.
When block is loaded block-loaded event is triggered after which one can set form field values in name, value pairs and trigger update-fields event.

<script>
window.addEventListener('block-loaded-form1', () => {
	const updateFields = new CustomEvent('update-fields-form1', {
			detail: {
				'Full Name': 'Softr',
				'Email': 'info@softr.io'
			}
	});
	window.dispatchEvent(updateFields);
});
</script>

form1 is the name of the block set in the softr studio block settings panel.

Thanks for sharing Arthur!

Is it possible to hide fields in Forms Blocks? What other events do Form Blocks listen to (other than update-fields); anything like hide-fields or show-fields?

Thanks,

Thank you very much for this code which works perfectly well. Do you have the event that a form waits for to fill in the options of a dropdown field? This would allow pre-filling the options via a script

@artur Are there any other custom events that we can listen to? I’m particularly interested in knowing when a Edit modal has been populated from its underlying datasource.

@artur Thanks for this. For me this code works only for a split-second and then the values are being reset to empty. Adding a setTimeoutwith 2000 works but it creates a laggy experience. Any ideas?

Hmm, this isn’t working for me. I confirmed the event is getting dispatched, and I changed the name of the form to the name I have in the interface, but the text in the text-box isn’t actually updating. Just to check - the ‘detail’ attributes are the names of the different fields in the form, correct?
