答案 0 :(得分:8)
您可以将正则表达式与Array#map
和parseInt(string, radix)
一起使用:
var hex = 'AA5504B10000B5'
var typedArray = new Uint8Array(hex.match(/[\da-f]{2}/gi).map(function (h) {
return parseInt(h, 16)
}))
console.log(typedArray)
console.log([0xAA, 0x55, 0x04, 0xB1, 0x00, 0x00, 0xB5])
var buffer = typedArray.buffer
