嗨，我在控制台中收到此错误：ie11中的“对象不支持属性或方法'forEach'”，但据我所知，nodelist不支持该对象，而是将它们添加到数组中。也使用babel。
<header class="main-header">
@if(config('adminlte.layout') == 'top-nav')
<nav class="navbar navbar-static-top">
<div class="container">
<div class="navbar-header">
<a href="{{ url(config('adminlte.dashboard_url', 'home')) }}" class="navbar-brand">
{!! config('adminlte.logo', '<b>Admin</b>LTE') !!}
</a>
<button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#navbar-collapse">

<div class="collapse navbar-collapse pull-left" id="navbar-collapse">

@else

<form id="logout-form" action="{{ url(config('adminlte.logout_url', 'auth/logout')) }}" method="POST" style="display: none;">
@if(config('adminlte.logout_method'))
{{ method_field(config('adminlte.logout_method')) }}
@endif
{{ csrf_field() }}
</form>
@endif
</li>
</ul>
</div>
</nav>
@if(config('adminlte.layout') == 'top-nav')
</div>
@endif
</nav>
</header>
我的代码中有很多，也许我可以以某种方式添加支持。
谢谢！

您应该使用下面的库在IE中支持es6语法

您也可以使用Array.from polyfill from MDN：
// Production steps of ECMA-262, Edition 6, 22.1.2.1
if (!Array.from) {
Array.from = (function () {
var toStr = Object.prototype.toString;
var isCallable = function (fn) {
return typeof fn === 'function' || toStr.call(fn) === '[object Function]';
};
var toInteger = function (value) {
var number = Number(value);
if (isNaN(number)) { return 0; }
if (number === 0 || !isFinite(number)) { return number; }
return (number > 0 ? 1 : -1) * Math.floor(Math.abs(number));
};
var maxSafeInteger = Math.pow(2, 53) - 1;
var toLength = function (value) {
var len = toInteger(value);
return Math.min(Math.max(len, 0), maxSafeInteger);
};
// The length property of the from method is 1.
return function from(arrayLike/*, mapFn, thisArg */) {
// 1. Let C be the this value.
var C = this;
// 2. Let items be ToObject(arrayLike).
var items = Object(arrayLike);
// 3. ReturnIfAbrupt(items).
if (arrayLike == null) {
throw new TypeError('Array.from requires an array-like object - not null or undefined');
}
// 4. If mapfn is undefined, then let mapping be false.
var mapFn = arguments.length > 1 ? arguments[1] : void undefined;
var T;
if (typeof mapFn !== 'undefined') {
// 5. else
// 5. a If IsCallable(mapfn) is false, throw a TypeError exception.
if (!isCallable(mapFn)) {
throw new TypeError('Array.from: when provided, the second argument must be a function');
}
// 5. b. If thisArg was supplied, let T be thisArg; else let T be undefined.
if (arguments.length > 2) {
T = arguments[2];
}
}
// 10. Let lenValue be Get(items, "length").
// 11. Let len be ToLength(lenValue).
var len = toLength(items.length);
// 13. If IsConstructor(C) is true, then
// 13. a. Let A be the result of calling the [[Construct]] internal method
// of C with an argument list containing the single item len.
// 14. a. Else, Let A be ArrayCreate(len).
var A = isCallable(C) ? Object(new C(len)) : new Array(len);
// 16. Let k be 0.
var k = 0;
// 17. Repeat, while k < len… (also steps a - h)
var kValue;
while (k < len) {
kValue = items[k];
if (mapFn) {
A[k] = typeof T === 'undefined' ? mapFn(kValue, k) : mapFn.call(T, kValue, k);
} else {
A[k] = kValue;
}
k += 1;
}
// 18. Let putStatus be Put(A, "length", len, true).
A.length = len;
// 20. Return A.
return A;
};
}());
}

使用此代码在IE 11中将NodeList转换为数组
var div_list = document.querySelectorAll('div'); // returns NodeList
var div_array = Array.prototype.slice.call(div_list); // преобразует NodeList в Array
