前端如何判断用户的电脑是 arm 还是 x86？-灵析社区
CTang前端如何判断用户的 mac 是 arm 还是 x86 [https://www.telerik.com/download/fiddler-everywhere](https://link.segmentfault.com/?enc=%2BBHyfQQdK7BCzrmzwOMhtg%3D%3D.VULg3EvL8%2BI112PqiHE2LYRf5moKNI1cO0kmcL78AMWwXwywN7eBwTKYPhurwdqdAi4c17Kn7ktawo1TFbyHAA%3D%3D) 下载 fiddler-everywhere 的时候，它监测到了我的电脑是 arm 怎么实现的？浏览器的 UA 都还是谎称自己是 intel  是通过 js 调用浏览器 API 获得的结果吗？对应的 API 是哪个呢？
九久九navigator.userAgentData.getHighEntropyValues(["architecture", "bitness"])
.then(ua => {
if (navigator.userAgentData.platform === "Windows") {
if (ua.architecture === 'x86') {
if (ua.bitness === '64') {
console.log("x86_64");
}
else if (ua.bitness === '32') {
console.log("x86");
}
}
else if (ua.architecture === 'arm') {
if (ua.bitness === '64') {
console.log("ARM64");
}
else if (ua.bitness === '32') {
console.log("ARM32");
}
}
}
else {
console.log("Not running on Windows");
}
});

截图中的用浏览器api就可以获取
navigator.userAgent;
