如何查找html表的最新修改（新添加或更改）行。

Answer 1

Plain way to achieve this by maintaining a flag in latest row.

let's say flag-name/class-name = "latest"

1) Remove all row with flag/class name latest

$('#resultTable tr').removeClass("latest");

2) when you add a new row add latest class to it

let's say newly added/modified row id is row1

$('#row1').addClass("latest");

you can get the latest row by calling.

var latest = $('.latest')[0];
