首页 / 脚本样式 / JavaScript / JS实现的用来对比两个用指定分隔符分割的字符串是否相同

// 示例用法/*var str1 = "tie, mao, 55";var str2 = "tie, mao, csdn";var result = diff（str1, str2, ","）; // 对象var rs = "" + result;// " 55, csdn"var df1 = result.diff1; // [" 55"]var df2 = result.diff2; // [" csdn"]*/// 比较2个字符串内元素的不同（字符1, 字符2, 分隔符可选）function diff（str1, str2, separator）{//str1 = str1 || "";str2 = str2 || "";separator = separator || ",";// arr中有ele元素function hasElement（arr, ele）{// 内存循环var hasItem1 = false;for（var i2=0; i2 < arr.length; i2++）{//var item2 = arr[i2] || "";if（！item2）{continue;}//if（ele == item2）{hasItem1 = true;break;}}return hasItem1;};function inAnotB（a, b）{ // 在A中，不在B中var res = [];for（var i1=0; i1 < a.length; i1++）{var item1 = a[i1] || "";if（！item1）{continue;}var hasItem1 = hasElement（b, item1）;if（！hasItem1）{res.push（item1）;}}return res;};//var list1 = str1.split（","）;var list2 = str2.split（","）;//var diff1 = inAnotB（list1, list2）;var diff2 = inAnotB（list2, list1）;// 返回结果var result = {diff1 : diff1,diff2 : diff2,separator : separator,toString : function（）{//var res = this["diff1"].slice（0）;res = res.concat（this["diff2"]）;//return res.join（this["separator"]）;}};//return result;};
