getAll() 方法在 FormData interface returns all the values associated with a given key from within a FormData 对象。

注意 : This method is available in Web 工作者 .

句法

formData.getAll(name);
					

参数

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

返回

An array of FormDataEntryValue s whose key matches the value passed in the 名称 parameter. If the key doesn't exist, the method returns an empty list.

范例

The following line creates an empty FormData 对象:

var formData = new FormData();
					

If we add two username values using FormData.append :

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

下列 getAll() function will return both username values in an array:

formData.getAll('username'); // Returns ["Chris", "Bob"]
