FormData: get() method

{{APIRef("XMLHttpRequest API")}} {{AvailableInWorkers}}

The get() method of the {{domxref("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 {{domxref("FormData.getAll()","getAll()")}} method instead.

Syntax

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 {{domxref("FormData")}} using {{domxref("FormData.append", "append()")}}:

formData.append("username", "Chris");
formData.append("username", "Bob");

The following get() method will only return the first username value:

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