以下代码适用于除 EI11 以外的所有浏览器。控制台或任何地方都没有显示错误。在过去的两天里，我一直在 Stack Overflow 上尝试所有其他已回答的问题，包括缓存破坏、添加 header 选项等任何问题。在这里迷路了，任何指导将不胜感激，我将添加所需的任何其他信息。

最佳答案
IE11 不支持 ES6。这意味着，您需要更换:
- 使用旧 ES5 语法的模板文字
'string' + 'string' - let/const with
var(正如@lostero 提到的，IE11 支持 let/const，but not fully)，因此最好避免使用它们。
或使用 ES6+ > ES5 转译器，如 Babel
无论如何，这是 IE 的代码:
$( document ).ready(function() {
var api_url2 = 'https://api.exchangeratesapi.io/latest?base=USD&symbols=TRY,BRL,MXN';
$.ajax({
type: 'GET',
url: api_url2 ,
dataType: 'json',
success: function(result){
const objVal = result.rates;
var keys = [], k, i, len;
for (k in objVal) {
if (objVal.hasOwnProperty(k)) {
keys.push(k);
}
}
keys.sort();
len = keys.length;
for (i = 0; i < len; i++) {
k = keys[i];
console.log(k + ':' + objVal[k]);
var column = $("<div class='column'></div>");
for (j = 0; j < 3; j++) {
// TODO: Should you match .row here, or use a specific row?
$(".row").append(column);
// Use jQuery to create the P element instead of the DOM.
var para = $('<p></p>');
// Use the jQuery text() method to set the content. (Prevents element
// injection by server via innerHTML.)
para.text(objVal[k].toFixed(3) + k );
// Append this element only to the one div we created this iteration of the
// outer loop.
column.append(para);
}
}
}
