javascript - 仅在 IE11 中首次单击时画廊灯箱不插入图像

标签 javascript jquery html css internet-explorer

我有一个画廊，它在除 IE11 之外的所有浏览器中都运行良好(震惊!)。

主要问题是，在 IE11 中，当您第一次单击图库元素时，它不会从数据属性中插入图像 url。如果您随后去加载下一张图片(使用灯箱导航或画廊缩略图)，img src 将更新并且工作正常。

我注意到的另一个问题仅存在于 IE11 中。gallery-navigation 计数器导航圆圈不会触发任何其他图像的加载。

我一直在环顾四周，发现 IE11 可能存在前置等问题，但我尝试更改此问题以及我在网上看到的其他一些解决方案，但我无法让画廊在 IE11 中正常工作

最佳答案

我尝试使用您的代码创建示例，它会向我显示此错误:

Error: Object doesn't support property or method 'from'

添加以下polyfill后，代码在IE浏览器上运行良好:

    // 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;
            };
        }());
    }

您可以检查 whole sample code .我这边的结果是这样的。
