Using modern ways, there are better, more reliable ways to get access token field:
使用现代方法，有更好、更可靠的方法来获取访问令牌字段：
var urlString = 'http://localhost:3000/_oauth/google#access_token=ya29.5HxuYol1Io8JLeGePDznbfkkwu_PC4uodKwG8_1clFYAn9AgdOV1WGpOTNQP3s76HAsn7Y4zWw&token_type=Bearer&expires_in=3600';
var url = new URL(urlString);
// OR: If you want to use the current page's URL
var url = window.location;
var access_token = new URLSearchParams(url.search).get('access_token');
You can also see how this approach makes it easy to get the other parameters in addition. This URLSearchParamsapproach is supported by all browsers except old instances of IE.
您还可以看到这种方法如何使获取其他参数变得更加容易。URLSearchParams除了旧的 IE 实例之外，所有浏览器都支持这种方法。
If the above doesn't work (didn't for me) just add 'hash' to window.location, this is also single line code
如果以上不起作用（不适合我），只需将“哈希”添加到window.location，这也是单行代码
var access_token = new URLSearchParams(window.location.hash).get('access_token');

I like RegEx so here's a RegEx answer:
我喜欢 RegEx 所以这是一个 RegEx 答案：
var url = 'http://localhost:3000/_oauth/google#access_token=ya29.5HxuYol1Io8JLeGePDznbfkkwu_PC4uodKwG8_1clFYAn9AgdOV1WGpOTNQP3s76HAsn7Y4zWw&token_type=Bearer&expires_in=3600',
access_token = url.match(/\#(?:access_token)\=([\S\s]*?)\&/)[1];
access_tokenis:
access_token是：
ya29.5HxuYol1Io8JLeGePDznbfkkwu_PC4uodKwG8_1clFYAn9AgdOV1WGpOTNQP3s76HAsn7Y4zWw
ya29.5HxuYol1Io8JLeGePDznbfkkwu_PC4uodKwG8_1clFYAn9AgdOV1WGpOTNQP3s76HAsn7Y4zWw

Make use of the URL class in JS:
使用 JS 中的 URL 类：
var token = new URL("http://localhost:3000/_oauth/google#access_token=ya29.5HxuYol1Io8JLeGePDznbfkkwu_PC4uodKwG8_1clFYAn9AgdOV1WGpOTNQP3s76HAsn7Y4zWw&token_type=Bearer&expires_in=3600").hash.split('&').filter(function(el) { if(el.match('access_token') !== null) return true; })[0].split('=')[1];
alert(token);
