在脚本开头添加如下代码
1 //filter 2 if (!Array.prototype.filter){ 3 Array.prototype.filter = function(fun){ 4 if (this === void 0 || this === null) 5 throw new TypeError(); 6 7 var t = Object(this); 8 var len = t.length >>> 0; 9 if (typeof fun !== "function") 10 throw new TypeError(); 11 12 var res = []; 13 var thisArg = arguments.length >= 2 ? arguments[1] : void 0; 14 for (var i = 0; i < len; i++){ 15 if (i in t){ 16 var val = t[i]; 17 if (fun.call(thisArg, val, i, t)) 18 res.push(val); 19 } 20 } 21 return res; 22 }; 23 } 24 25 //map 26 if (!Array.prototype.map) { 27 Array.prototype.map = function(callback, thisArg) { 28 var T, A, k; 29 if (this == null) { 30 throw new TypeError(" this is null or not defined"); 31 } 32 var O = Object(this); 33 var len = O.length >>> 0; 34 if (typeof callback !== "function") { 35 throw new TypeError(callback + " is not a function"); 36 } 37 if (thisArg) { 38 T = thisArg; 39 } 40 A = new Array(len); 41 k = 0; 42 while(k < len) { 43 var kValue, mappedValue; 44 if (k in O) { 45 kValue = O[ k ]; 46 mappedValue = callback.call(T, kValue, k, O); 47 A[ k ] = mappedValue; 48 } 49 k++; 50 } 51 return A; 52 }; 53 }
在实现HTML table中粘贴excel复制数据时发现chrome正常，但是IE8未无法实现这一功能，通过排查发现IE8中并不支持filter、map等方法
如下是实际应用
