jquery - 我正在使用 JQuery 从模式输入中更新表行值，但我遇到了一个小问题。任何人都可以看看并提供一些建议吗？

问题描述

我的更新/编辑表功能遇到了一个奇怪的问题。该功能似乎适用于 1 行，但是当我添加超过 1 行时，我得到了问题。最近的行值被复制到模式中，而不是该行的值。然后更新该行会更新该行和第一行。我现在对这个问题很困惑。

任何人都可以对这件事有所了解吗？我确定这是一个逻辑问题。

行是从“添加到表”按钮添加的，该按钮在单击时调用函数。

function editRow()
{
    $("#myTable tbody").on('click', '#edit', function (x) {

        let row = x.target.parentNode.parentNode;
        let name = $('#Name').val();//row.cells[1].textContent;
        let surname = $('#Surname').val(); //row.cells[2].textContent;
        console.log(row);
        console.log("Original name: " + name);
        console.log("Original surname: " + surname);//same thing
        //set edit modal values
        let edit_modal_name = $('#edit_Name').val(name);
        let edit_modal_surname = $('#edit_Surname').val(surname);


        console.log("Edit modal name: " + edit_modal_name.val());
        console.log("Edit modal surname: " + edit_modal_surname.val());

        $('#edit_modal').modal('show');

        $('#save_btn_edit').click(function () {
            row.cells[1].textContent =  $('#edit_Name').val();
            row.cells[2].textContent =  $('#edit_Surname').val();
            console.log(row);
        })
    });
}
