比较2个字符串内元素的不同(字符1, 字符2, 分隔符可选)
文件: diff.js
// 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;};请根据需要使用, 我用来比较在2个Oracle数据库中导出的表有那些没导入成功.
