引入表数据的Json代码：
{
"person": [
{
"firstName": " ",
"lastName": "Kent",
"job": "Reporter",
"roll": 20,
"hours":10
},
{
"firstName": " ",
"lastName": "Wayne",
"job": "Playboy",
"roll": 30,
"hours":20
}
]
}
我在行开头使用的按钮只能用于其他每一行。该按钮基本上允许该人接受或拒绝给定行内的数据，因此每行都需要该按钮。该表必须是动态的，以便从本地HTML页面以外的源读取信息。如果我要添加3个表行，则三个按钮中只有两个会起作用，即使这样，有时模态视图也会停止工作。例如，一旦按下按钮，模态视图就会出现另外两个按钮，如果您单击这些按钮之一，视图将关闭。但是当添加更多行时，单击初始行中的按钮时，模态视图中的按钮（在单击表格行内的按钮后出现的按钮）不起作用。这是在初始按钮的顶部，仅适用于其他每一行。
答案 0 :(得分：1)
如果在添加所有行后添加处理程序怎么样？
$(function() {
var people = [];
$.getJSON('datasource/people.json', function(data) {
$.each(data.person, function(i, f) {
var tblRow = "<tr>" + "<td><button class='button-border toggleModal'><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");
});
// Add the click handler after adding all table rows
$('#userdata').on('click', '.toggleModal', function (e) {
$('.modal').toggleClass('active');
});
});
});
否则，您将在第一行添加一次处理程序，在第二行添加两次，在第三行添加三次等等。
这就是为什么它适用于其他所有行。切换两次（或任何可被2整除的数字）将导致它打开然后关闭。
此外，您的<tbody>位置奇怪（位于您的内部）。
