[英]getting error in EDGE and IE11 Object doesn't support property or method 'waitUntil'" using method in service-worker.js
[英]Using react polyfills but getting error Object doesn't support property or method 'repeat' in IE11
我正在使用 react polyfills,並且該站點在 IE11 中工作,除非使用
changeHeight() {
let height = 0;
for (let child of this.Element.current.children) {
height = Math.max(height, child.clientHeight);
}
this.Element.current.style.height = `${height}px`;
}
IE 中的錯誤是Object 不支持屬性或方法“重復”
我在 package.json 中定義了瀏覽器並導入了以下內容
但頁面不會呈現。
我也收到錯誤
SCRIPT5022:拋出異常但未捕獲
main.chunk.js (6068,465)
IE 11 不支持新的 ECMAScript 2015 的repeat()
方法。 您可以添加以下polyfill來修復它:
if (!String.prototype.repeat) {
String.prototype.repeat = function(count) {
'use strict';
if (this == null)
throw new TypeError('can\'t convert ' + this + ' to object');
var str = '' + this;
// To convert string to integer.
count = +count;
// Check NaN
if (count != count)
count = 0;
if (count < 0)
throw new RangeError('repeat count must be non-negative');
if (count == Infinity)
throw new RangeError('repeat count must be less than infinity');
count = Math.floor(count);
if (str.length == 0 || count == 0)
return '';
// Ensuring count is a 31-bit integer allows us to heavily optimize the
// main part. But anyway, most current (August 2014) browsers can't handle
// strings 1 << 28 chars or longer, so:
if (str.length * count >= 1 << 28)
throw new RangeError('repeat count must not overflow maximum string size');
var maxCount = str.length * count;
count = Math.floor(Math.log(count) / Math.log(2));
while (count) {
str += str;
count--;
}
str += str.substring(0, maxCount - str.length);
return str;
}
}
