Hidden field revealed when date / time field is changed

Avatar

Former Community Member

Hi,

How can I code my form so that when a user selects a date in the date / time field  it will then reveal a hidden text field, I am assuming this would be a "change" in javascript rather than on "exit".

Would appreciate any advice.

Thanks

You can use presence property to hide/ display the fields.

FieldName.presence = "visible"; // Display the field.

FieldName.presence = "hidden"; // Hides the field.

You can decide on the event you want to place the code in based on your requirements. Exit event will be executed when the user leaves the field. Change event will be executed when the value changes in the field.

Thanks

To specifiy when to run the presence code you can use the Date2Num function. This will translate a date into a number and then you can say that when the Date2Num result is equal to the date you want then the presence will change.
