- def readAsArrayBuffer(blob: Blob): ArrayBuffer
The readAsArrayBuffer method is used to starts reading the contents of the specified Blob or File.
The readAsArrayBuffer method is used to starts reading the contents of the specified Blob or File. When the read operation is finished, the readyState becomes DONE, and the loadend is triggered. At that time, the result attribute contains an ArrayBuffer representing the file's data.
- def readAsDataURL(blob: Blob): URL
The readAsDataURL method is used to starts reading the contents of the specified Blob or File.
The readAsDataURL method is used to starts reading the contents of the specified Blob or File. When the read operation is finished, the readyState becomes DONE, and the loadend is triggered. At that time, the result attribute contains a data: URL representing the file's data as base64 encoded string.
- def readAsText(blob: Blob, encoding: String = js.native): String
The readAsText method is used to read the contents of the specified Blob or File.
The readAsText method is used to read the contents of the specified Blob or File. When the read operation is complete, the readyState is changed to DONE, the loadend is triggered, and the result attribute contains the contents of the file as a text string.
