This article mainly introduces how to use JavaScript to compare whether two strings separated by the specified separator are the same. The code in this article is written for special needs, for more information, see <G id = "1"> 2 </G>)

File: diff. js

// Example usage/* var str1 = "tie, mao, 55"; var str2 = "tie, mao, csdn"; var result = diff (str1, str2 ,', '); // object var rs = "" + result; // "55, csdn" var df1 = result. diff1; // ["55"] var df2 = result. diff2; // ["csdn"] * // compare the elements in two strings (character 1, character 2, separator optional) function diff (str1, str2, separator) {// str1 = str1 | ""; str2 = str2 | ""; separator = separator | ","; // arr contains the ele element function hasElement (arr, ele) {// memory loop va R 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) {// In A, var res = []; for (var i1 = 0; i1 <. 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); // return result 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 ;};

Please use it as needed. I used to compare tables exported in two Oracle databases that have not been imported successfully.
