javascript - 向表中添加更多行后，模态 onclick 按钮不起作用

标签 javascript html css onclick bootstrap-modal

这是我的一小段代码:https://jsfiddle.net/DurangoJohnson/bmg0fLvL/2/

目前在 fiddle 中它显示 5 行。如果您要添加另一行，则单击该行中的按钮后弹出的模态窗口中的按钮将不起作用。

这是一个包含 6 行的表格，作为确切错误的引用: https://jsfiddle.net/DurangoJohnson/bmg0fLvL/3/

我假设需要修复的是向行添加一个 id。对于我想要完成的工作，我想让 employeeNum 字段成为 id(我喜欢这种方法，因为它会更加动态和灵活，而不是在表数据本身中为每个条目提供一个静态 id)。是的，列名称和内部的实际数据不相关，因为这仍在进行中，只是试图让功能方面发挥作用。 

 $(function() {

        var people = [];
var data = {
  "person": [
   {

       "firstName": " ",
       "lastName": "Kent",
       "job": "Reporter",
       "roll": 20,
       "hours":10
   },
   {
       "firstName": " ",
       "lastName": "Wayne",
       "job": "Playboy",
       "roll": 30,
       "hours":20
   },
    {
    "firstName": " ",
    "lastName": "Scott",
    "job": "PaperMan",
    "roll": 20,
    "hours": 40
   },
    {
    "firstName": " ",
    "lastName": "Mike",
    "job": "writer",
    "roll": 12,
    "hours": 30
   },
    {
    "firstName": " ",
    "lastName": "Charlie",
    "job": "Driver",
    "roll": 2,
    "hours": 23
   }
           ]
        };

var row = 0;

$.each(data.person, function(i, f) {
  var tblRow = "<tr>" + "<td><button class='button-border toggleModal toggleModalFromTable'><span class='icon'></span> Timesheet Approval</button></td>" + "<td>" + f.lastName + "</td>" + "<td>" + f.job + "</td>" + "<td>" + f.roll + "</td>" + "<td>" + f.hours + "</td>" + " </tr>"
  $(tblRow).appendTo("#userdata tbody");
  $('#userdata').on('click', '.toggleModalFromTable',  function (e) {
        row = $(this).closest('tr').index() + 1;
    $('.modal').toggleClass('active');
        });

尝试将您的点击事件处理程序从每个循环中取出。 您只需将处理程序附加到表一次。

var people = [];
var data = {
  "person": [{
    "firstName": " ",
    "lastName": "Kent",
    "job": "Reporter",
    "roll": 20,
    "hours": 10
  }, {
    "firstName": " ",
    "lastName": "Wayne",
    "job": "Playboy",
    "roll": 30,
    "hours": 20
  }, {
    "firstName": " ",
    "lastName": "Scott",
    "job": "PaperMan",
    "roll": 20,
    "hours": 40
  },
    {
    "firstName": " ",
    "lastName": "Mike",
    "job": "writer",
    "roll": 12,
    "hours": 30
   },
    {
    "firstName": " ",
    "lastName": "Charlie",
    "job": "Driver",
    "roll": 2,
    "hours": 23
   },
   {    
    "firstName": " ",
    "lastName": "Tom",
    "job": "Cook",
    "roll": 1,
    "hours": 40
    }

  ]
};

var row = 0;

$('#userdata').on('click', '.toggleModalFromTable', function(e) {
  row = $(this).closest('tr').index() + 1;
  $('.modal').toggleClass('active');
});

$.each(data.person, function(i, f) {
  var tblRow = "<tr>" + "<td><button class='button-border toggleModal toggleModalFromTable'><span class='icon'></span> Timesheet Approval</button></td>" + "<td>" + f.lastName + "</td>" + "<td>" + f.job + "</td>" + "<td>" + f.roll + "</td>" + "<td>" + f.hours + "</td>" + " </tr>"
  $(tblRow).appendTo("#userdata tbody");

});

$('.approve').click(function() {
  $('.modal').toggleClass('active');
  $('table tbody tr:nth-child(' + row + ')').remove();
});

$('.disapprove').click(function() {
  $('.modal').toggleClass('active');
  $('table tbody tr:nth-child(' + row + ')').css({
