Private #privateAppends a new value onto an existing key inside a FormData object, or adds the key if it does not already exist.
The difference between set() and append() is that if the specified key already exists, set() will overwrite all existing values with the new one, whereas append() will append the new value onto the end of the existing set of values.
The name of the field whose data is contained in value.
Optional fileName: stringThe filename reported to the server, when a Blob or File is passed as the second parameter. The default filename for Blob objects is "blob". The default filename for File objects is the file's filename.
Returns an iterator allowing to go through the FormData key/value pairs.
The key of each pair is a string; the value is a FormDataValue.
Executes given callback function for each field of the FormData instance
Optional thisArg: unknownReturns 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.
A name of the value you want to retrieve.
A FormDataEntryValue containing the value. If the key doesn't exist, the method returns null.
Returns all the values associated with a given key from within a FormData object.
A name of the value you want to retrieve.
An array of FormDataEntryValue whose key matches the value passed in the name parameter. If the key doesn't exist, the method returns an empty list.
Returns an iterator allowing to go through all keys contained in this FormData object.
Each key is a string.
Set a new value for an existing key inside FormData, or add the new field if it does not already exist.
The name of the field whose data is contained in value.
Optional fileName: stringThe filename reported to the server, when a Blob or File is passed as the second parameter. The default filename for Blob objects is "blob". The default filename for File objects is the file's filename.
Returns an iterator allowing to go through all values contained in this object FormData object.
Each value is a FormDataValue.
Static [hasGenerated using TypeDoc
Provides a way to easily construct a set of key/value pairs representing form fields and their values, which can then be easily sent using fetch().
Note that this object is not a part of Node.js, so you might need to check if an HTTP client of your choice support spec-compliant FormData. However, if your HTTP client does not support FormData, you can use
form-data-encoderpackage to handle "multipart/form-data" encoding.
