FormData.getAll()
The getAll()
method of the FormData
interface returns all the values associated with a given key from within a FormData
object.
Note: This method is available in Web Workers.
Syntax
formData.getAll(name);
Parameters
name
-
A
USVString
representing the name of the key you want to retrieve.
Returns
An array of FormDataEntryValue
s whose key matches the value passed in the name
parameter. If the key doesn't exist, the method returns an empty list.
Example
The following line creates an empty FormData
object:
var formData = new FormData();
If we add two username
values using FormData.append
:
formData.append('username', 'Chris');
formData.append('username', 'Bob');
The following getAll()
function will return both username
values in an array:
formData.getAll('username'); // Returns ["Chris", "Bob"]
