FormData: get() method
Baseline
Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since October 2018.
Note: This feature is available in Web Workers.
The get() method of the FormData interface
returns the first value associated with a given key from within a FormData
object. If you expect multiple values and want all of them, use the
getAll() method instead.
Syntax
js
get(name)
Parameters
name-
A string representing the name of the key you want to retrieve.
Return value
A value whose key matches the specified name. Otherwise, null.
Examples
If we add two username values to a FormData using append():
js
formData.append("username", "Chris");
formData.append("username", "Bob");
The following get() method will only return the first username value:
js
formData.get("username"); // Returns "Chris"
