Basket Page - Shipping Estimator IE11

[influxweb]

In Internet Explorer 11 the shipping estimator will open but, when submitted, the form will not process and the console will receive the error SCRIPT438: Object doesn't support property or method 'before'.

Expected Behavior

The form should function in all browsers without errors

Correcting the Issue

To correct the issue, a new function needs to be added to the polyfills.js file. I have added this update and it will be included in the next maintenance release.

To make the update prior to the next release, you will need to add this code in User Interface -> JavaScript Resources -> polyfills:

/**
 * A basic polyfill for the before() method in Internet Explorer 9 and higher.
 *
 * https://developer.mozilla.org/en-US/docs/Web/API/ChildNode/before
 * https://github.com/jserz/js_piece/blob/master/DOM/ChildNode/before()/before().md
 */
(function (arr) {
	arr.forEach(function (item) {
		if (item.hasOwnProperty('before')) {
			return;
		}
		Object.defineProperty(item, 'before', {
			configurable: true,
			enumerable: true,
			writable: true,
			value: function before() {
				var argArr = Array.prototype.slice.call(arguments);
				var docFrag = document.createDocumentFragment();

				argArr.forEach(function (argItem) {
					var isNode = argItem instanceof Node;

					docFrag.appendChild(isNode ? argItem : document.createTextNode(String(argItem)));
				});

				this.parentNode.insertBefore(docFrag, this);
			}
		});
	});
})([Element.prototype, CharacterData.prototype, DocumentType.prototype]);
