如何使用JavaScript定位Edge浏览器 [英] How to target Edge browser with javascript

问题描述

我知道您应该尽可能进行特征检测，但是如果浏览器是Microsoft Edge浏览器，是否可以使用Javascript进行检测?

I know you should do feature detection where possible, but can you detect in Javascript if the browser is the Microsoft Edge browser?

我维护的是旧产品，但我想显示警告，指出某些功能可能会被破坏，而不必花费大量时间来修复旧代码.

I maintain an old product and I want to display a warning that some features could be broken without having to invest a lot of time fixing the old code.

推荐答案

尝试检测功能而不是特定的浏览器.更具前瞻性.很少使用浏览器检测.

顺便说一句:一种选择是使用库(用户代理字符串有很多复杂性)，或者手动解析window.navigator.userAgent.

With that out of the way: one option is to use a library (there are many intricacies to User Agent strings), or alternatively to parse window.navigator.userAgent manually.

使用解析器库

# https://github.com/faisalman/ua-parser-js.

var parser = new UAParser();
var result = parser.getResult();

var name = result.browser.name;
var version = result.browser.version;

使用Java的原始方法

# Mozilla/5.0 (Windows NT 10.0) AppleWebKit/537.36 (KHTML, like Gecko) \
# Chrome/42.0.2311.135 Safari/537.36 Edge/12.10136

window.navigator.userAgent.indexOf("Edge") > -1
