复制代码代码如下:以前项目中用到自己写的，应该没有bug吧，有更好的也欢迎大家指教，var Return_AddStrFn=function (oldArr, newArr) {var t = this;//去重复的方法Array.prototype.unique4 = function () {// this = arr;var temp = new Array();this.sort();for (i = 0; i if (this[i] == this[i + 1]) {continue;}temp[temp.length] = this[i];}return temp;}var a = d = oldArr.unique4(); //旧数组var b = e = newArr.unique4();//新数组var c = [];var dels = [];function f() {a.sort();b.sort();var i = 0;var j = 0;while (i if (a[i] c.push(a[i]);i++;} else if (b[j] c.push(b[j]);j++;} else {i++;j++;}}while (i c.push(a[i]);i++;}while (j c.push(b[j]);j++;}}f();//alert("c:" + c);//alert("d:" + d);var addstr = [];for (var i = 0; i for (var j = 0; j if (e[j] == c[i]) {addstr.push(e[j]);}}}return addstr; //新增的//for (var i = 0; i // for (var j = 0; j // if (d[j] == c[i]) {// dels.push(d[j]);// }// }//}//alert("dels:" + dels); //删除的}调用方式： var arr = [1, 2,2,3, 3, 4, 5];var arr2=[1,2,5]var addStr=Return_AddStrFn(arr2,arr);php版微信js-sdk支付接口类php版微信js-sdk支付接口类下载
