I have a form. If a patient has not entered any allergies into the $w( ‘#allergies’ ).value field on clicking the Submit button, I want the $w( ‘#allergies’ ).value in the collection to update to “Sin alergias conocidas”
export function submit_click(event) {
if ($w( ‘#allergies’ ).value === “” ) {
$w( ‘#allergies’ ).value = “Sin alergias conocidas” ;
}
}
Any help would be greatly appreciated.
I don’t see your code for saving to collection.
Does the submit button not save it for me?
@digitalzemb it probably saved before executing the onClick function.
You should disconnect this button from the dataset and submit using code.
Alternatively, you can move the code to a beforeInsert hook in the backend data.js file.
@jonatandor35 Thanx… Still learning about beforeInsert. I have many fields that need to be added to the collection as the record is saved. But when I use the “If” statement to update the one particular field… it doesn’t get saved with the rest of the data.
@digitalzemb as I said you can save the field that way.
you should read:

@jonatandor35 You are a star. Thanx. I have so many questions but will post them one by one.
You’re welcome 
@jonatandor35 Got it working.
I setFieldValues to update that one field $w( ‘#allergies’ ).value called “allergies” with “Sin alergias conocidas”
ie. “allergies” : “Sin alergias conocidas”
My code:
$w.onReady( function () {
const allergy = $w( ‘#allergies’ ).value;
if (allergy === “” ){
$w( “#ptDataset” ).onReady( () => {
$w( “#ptDataset” ).setFieldValues( {
“allergies” : “Sin alergias conocidas”
} );
} );
}
});
