is there any way to get uint8Array data with cefv8value?

[colinChan008]

as tile, except scheme .I want to get the memory pointer directly just something like "(uint8_t*)target->Buffer()->GetBackingStore()->Data()" in v8.

You can create an array backed by a native buffer with CefV8Value::CreateArrayBuffer.

If I want to get the buffer'pointer of original v8 Arraybuffer, how to do it.

Getting the pointer is not supported. You would need to read the data out in JavaScript and then submit the data to native code via some other mechanism.
