FormData.get()

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.

Note: This method is available in Web Workers.

Syntax

formData.get(name);

Parameters

name

A USVString representing the name of the key you want to retrieve.

Return value

A FormDataEntryValue containing the value. If the key doesn't exist, the method returns null.

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 get() function will only return the first username value appended:

formData.get('username'); // Returns "Chris"
