using typed-arrays-polyfill error

[zhengtg]

using typed-arrays-polyfill to send msg by websocket, and capture package by wireshark,
the opcode of package is text(0001). without using polyfill, the opcode value is binary (0010) .

ps:
already set websocket binaryType is "arraybuffer";

If you have to use a polyfill, binaryType="arraybuffer" is probably not supported by the (older) browser.

[zhengtg]

oh, yes, polyfill maybe not supported "arraybuffer", i'am sure my browser supported arraybuffer

[dcodeIO]

What I wanted to say is that if you have to use a polyfill because DataView or something isn't supported, XmlHttpRequest most likely also doesn't support ArrayBuffers as a payload. The sole existence of ArrayBuffers doesn't imply that XmlHttpRequest already supports them.
