以下有关 Mixitup.js 的代码在 Internet Explorer 中不起作用，但在所有其他浏览器中都可以正常工作。

任何人都可以帮助解决这个问题，或者可以调整在 Internet Explorer 中工作的代码吗？

// 2) Reusable function to convert any string/text to css-friendly format
  var conv = function (str) {
    if (!str) {
        str = 'empty';
    }  return str.replace(/[!\"#$%&'\(\)\*\+,\.\/:;<=>\?\@\[\\\]\^`\{\|\}~]/g, '')
              .replace(/ /g, "-")
              .toLowerCase()
              .trim();
  };

// 3) Creating dynamic elements classes from its categories for filtering:
  var catArray = document.querySelectorAll('.w-dyn-item .filter-category');
  catArray.forEach( function(elem) {
    var text = elem.innerText || elem.innerContent;
    var className = conv(text);
    elem.parentElement.parentElement.parentElement.parentElement.classList.add(className);
  });

// 4) Creating custom data-date attributes from blog dates:
  var sortArray = document.querySelectorAll('.w-dyn-item .sort-category');
  sortArray.forEach( function(sortElem) {
    var sortText = sortElem.innerText || sortElem.innerContent;
    sortElem.parentElement.parentElement.setAttribute('data-date', sortText);
  });

// 5) Set the reference to the container. Use the class-name of your Collection List or ID of the Collection List
  var containerEl = document.querySelector('.collection-list');

// 6) Call the MixitUp plugin
  mixitup(containerEl);

我在 IE 中运行您的代码，它显示错误Object doesn't support property or method 'forEach'。ForEach是为 NodeList 而不是 HTMLCollection 定义的。我们可以forEach对 HTMLCollection 进行 polyfill，然后它可以用于 IE 中的 NodeList 和 HTMLCollection。

填充物：

var ctors = [typeof NodeList !== "undefined" && NodeList, typeof HTMLCollection !== "undefined" && HTMLCollection];
for (var n = 0; n < ctors.length; ++n) {
    var ctor = ctors[n];
    if (ctor && ctor.prototype && !ctor.prototype.forEach) {
        // (Yes, there's really no need for `Object.defineProperty` when doing the `forEach`)
        ctor.prototype.forEach = Array.prototype.forEach;
        if (typeof Symbol !== "undefined" && Symbol.iterator && !ctor.prototype[Symbol.iterator]) {
            Object.defineProperty(ctor.prototype, Symbol.iterator, {
                value: Array.prototype[Symbol.itereator],
                writable: true,
                configurable: true
            });
        }
    }
}
