javascript - IE11/Windows 10 => 对象不支持属性或方法“包含”

Question

在 Windows 10 上的 IE11 中，我得到Object doesn't support property or method 'includes' error on Cookie.set('something', null). 以前我有Cookie.remove('something')，这给出了同样的错误。

  Cookie = require('js-cookie')
  Cookies.set('save_lead', null)
  // used to be:
  // Cookies.remove('save_lead')

我使用array-includes npm 包找到了解决方案。乍一看，它看起来只是给你一个 call 的替代品，arr.includes('foo')但它也允许一个 shim。

来自 github 自述文件：

var includes = require('array-includes');
var assert = require('assert');
/* when Array#includes is not present */
delete Array.prototype.includes;
var shimmedIncludes = includes.shim();

assert.equal(shimmedIncludes, includes.getPolyfill());
assert.deepEqual(arr.includes('foo', 1), includes(arr, 'foo', 1));

希望它可以帮助别人。
