От това, което разбрах, търсите начин да подчертаете разликите в текста, за да видите разликите между описанията. От там мога да предложа да ограничите функцията diff само до b_discription тъй като другите атрибути не изглеждат в обхвата на това, от което се нуждаете. Очаквате ли business_logo , business_name или mod_date да се промени? Независимо от това, следната функция може да бъде изпълнена върху всички атрибути във вашия обект, ако могат да бъдат преобразувани в низ.
simplediff е отличен скрипт, който намира разликата между два низа, включително:
- Съществува в A, а не в B (Изтриване)
- Съществува в B, а не в A (вмъкване)
