Interlude.Result.GetString
In Depth¶
Result.GetString(result, key, fallback: "")
A field's answer as text.
Works on any field, not just text ones: a number comes back as its printed form, a choice as the display name of what was chosen. Handy for building a filename or a parameter value out of whatever the user picked.
A missing or empty field gives the fallback, so the answer is never null and never needs guarding before it is concatenated.
The inputs are:
result(object) — The values dictionary or the form output of Form.Show.key(string) — The field to read.fallback(string, defaults to"") — Returned when the field is missing or empty.
Returns value — The answer as text.
Search terms: string, text, get, read.
About the Result nodes¶
Reading a form's answers.
Every node here accepts either the values dictionary or the form output of Form.Show, so it does not matter which one is to hand. They exist so a graph can say what it expects — a number, a date, a colour — rather than pulling an object out of a dictionary and hoping. Each one takes a fallback used when the field is missing or empty, which is what keeps a downstream node from receiving a null it was not expecting.
