HTML Preparation code:
<!--your preparation HTML code goes here-->
Script Preparation code:
const str = "111111"; const encoder = new TextEncoder(); const uint8Array = encoder.encode(str); const buffer = uint8Array.buffer; const blob = new Blob([buffer]);
Tests:
buffer
const metaDataLength = new DataView(buffer).getUint8(0); const metaDataRaw = new Uint8Array(buffer, 1, metaDataLength); const mainDataRaw = new Uint8Array(buffer, 1 + metaDataLength); const mainData = new Blob([mainDataRaw]); const metaData = new TextDecoder().decode(metaDataRaw);
blob
(async () => { const metaDataLength = (await blob.slice(0, 1).bytes())[0]; const metaDataBlob = blob.slice(1, metaDataLength); const mainData = blob.slice(1 + metaDataLength); const metaData = await metaDataBlob.text(); })();
