But html table only show the FirstNmae and Lastname.
但是 html 表只显示 FirstNmae 和 Lastname。
Where to store the person id ,if it hidden it will not get in javascript and space problem also.
在哪里存储人员 ID，如果它隐藏它也不会出现在 javascript 和空间问题中。
My need is to, make the rows doubleclickable and that time get the personID and second is to hide the person id from the enduser.

解决方案
The problem is that the event is firing for the tdelement, so thisrefers to the tdelement. You need to get the parent trand then call the findfunction.
问题是事件正在为td元素触发，因此this引用td元素。您需要获取父项tr，然后调用该find函数。
Something like this:
像这样的东西：
$('#EditTable td').dblclick(function () {
var $this = $(this);
var row = $this.closest("tr");
row.find('td:eq(1)');
row.find('td:first').text();
}); //<-- NOTE: you dont close correctly in your example, which cause console errors
Alternatively, you could assign the event to the trelement instead, which would allow you to keep your original function code...
或者，您可以将事件分配给tr元素，这将允许您保留原始功能代码...
$('#EditTable tr').dblclick(...
Personally, I would prefer to store "metadata" type things using a dataattribute. For example:
就个人而言，我更喜欢使用data属性来存储“元数据”类型的东西。例如：
$('#EditTable td').dblclick(function () {
var $this = $(this);
var row = $this.closest("tr");
var id = row.data("id");
});
with the following html table:
使用以下 html 表：
<table id="EditTable">
<tr data-id="1">
<td>1</td><td>One</td>
</tr>
</table>

Actually you can store the model details in DOM tree using $.data('personID',1)method. In that way you can hide the personIDfrom the user. When the user dbl clicks on a row, get the corresponding personIDlike $.data('personID')
实际上，您可以使用$.data('personID',1)方法将模型详细信息存储在 DOM 树中。通过这种方式，您可以personID对用户隐藏。当用户 dbl 点击一行时，得到对应的personIDlike$.data('personID')
//setting the personID
$.data('personID',2);
//getting the personID
$.data('personID'); //returns 2

You have to write:
你必须写：
// You want event fired on row `tr` and not on `td`
$('#EditTable tr').dblclick(function () {
$(this).find('td:eq(1)')
$(this).find('td:first').text()
}
Edit
编辑
Best way would be:
最好的方法是：
$('#EditTable').on(dblclick, 'tr', function () {
var $rowClicked = $(this);
var secondCell = $rowClicked.find('td:eq(1)');
var textOfFirstCell $rowClicked.find('td:first').text();
}

try this
试试这个
$('#EditTable tr').dblclick(function () {
var $this=$(this);
$this.find('td:first').text(); //get personid
$this.find('td:first').hide(); //hide the personrow... u can use remove()
});

try this one:
试试这个：
$('#EditTable tr').dblclick(function () {
$(this).find('td:eq(1)')
$(this).find('td:first').text()
});
Try to iterate through TRsinstead and may be that's a typo or what you have a error at closing that should be });
尝试迭代TRs，这可能是一个错字或者你在关闭时有错误应该是});
