<caption>Table 1</caption>
<thead>
<tr>
<th></th>
<th >ID</th>
<th> Name</th>
<th>System</th>
</tr>

<tbody>
<tr>
<td><input type="checkbox" /></td>
<td>12</td>
<td>Sam</td>
<td>FSS</td>
</tr>
<tr>
<td><input type="checkbox" /></td>
<td>87</td>
<td>Harry</td>
<td>MSS</td>
</tr>
<tr>
<td><input type="checkbox" /></td>
<td>23</td>
<td>Rita</td>
<td>MVV</td>
</tr>
<tr>
<td><input type="checkbox" /></td>
<td>65</td>
<td>Tom</td>
<td>RDD</td>
</tr>
</tbody>
</table>

<button id="add">Add</button>
</body>
</html>
Here, when I click on add button I want to get all the values of the corresponding row that is checked in different variables namely id, name & system that should contain the checked values. 在这里，当我单击添加按钮时，我想获取在不同变量（即id，name和system中应检查的值）中检查的相应行的所有值。
I want these values to be stored in a String (not map). 我希望这些值存储在字符串（不是映射）中。 Could you please suggest me a jquery / js to achieve the folllowing 你能建议我一个jQuery / JS实现以下
UPDATE UPDATE
If I have a hidden field along with the checkbox how can I get its value? 如果我的复选框旁边有一个隐藏字段，如何获取其值？ For example 例如
<td>
<input type="checkbox" />
<input type="hidden" value="secret" id="alertTyp" />
</td>

Try this: 尝试这个：
var stringresult = '';
$('#add').on('click', function () {
$('input:checked').each(function () {
$this = $(this);
var one = $this.parent().siblings('td').eq(0).text();
var two = $this.parent().siblings('td').eq(1).text();
var three = $this.parent().siblings('td').eq(2).text();
alert(one + ' ' + two + ' ' + three);
//or just
stringresult += $this.parent().siblings('td').text();
});
console.log(stringresult);
});

You can iterate through all the rows...the question how performand would that be: 您可以遍历所有行...性能如何的问题，那将是：
var str = '';
$('#one').find('tbody').find('tr').each(function()
{
if($(this).children().eq(0).attr('checked') == 'checked')
{
$(this).find('td').each(function()
{
str += $(this).text();
});
}
});
or something like that ...i don't have the time atm to test this sorry. 或类似的东西...我没有时间atm来测试这个抱歉。

I would do something like this (untested code!!!) : 我会做这样的事情（未经测试的代码！！！）：
var myRow = $('input[type="checkbox"]:checked').parents('tr:first');
var result;
myRow.children('td').each(){
result += $(this).html() + "|";
}
this could work if there was only 1 checked checkbox... otherwise you need to cycle through all the checked checkboxes to get values... 如果只有1个选中的复选框，这可能会起作用...否则，您需要循环遍历所有选中的复选框才能获取值...
