JQuery 清除 HTML 表并插入新行 [英] JQuery clear HTML table and insert new rows

问题描述

我一直在四处寻找，但找不到有效的解决方案.

I have been scouting around but cannot find a solution that works.

我有一个简单的 HTML 表格:

I have a simple HTML table:

<table id="myTable">
        <thead>
            <tr>
                <th>UserID</th>
                <th>Current Submissions</th>
            </tr>
        <tbody>
            <tr>
            </tr>
        </tbody>
        <thead>
    </table>

使用 socket.io 我正在接收 JSON 数据，我会在清除它后将其附加到表中.下面的代码只是删除表而不插入新数据?

using socket.io I am receiving JSON data that I would to append to the table, after clearing it. The code below just deletes the table and doesn't insert the new data?

<script>
    var socket = io();
    socket.on('totalsubmissions', function(msg) {
        $('#myTable').find('tbody').remove();
        // loop over each recevied in the object
        $.each(msg, function(k, v) {
            //display the key and value pair
            var myRow = "<tr><td>" + k + "</td><td>" + v + "</td></tr>";
            $('#myTable').find('tbody').append(myRow);
        });

    });
</script>

我是否错误地删除了表格?

Am I removing the table incorrectly?

推荐答案

这一行删除了 tbody.

$('#myTable').find('tbody').remove();

所以当你到达这一行时:

So when you get to this line:

$('#myTable').find('tbody').append(myRow);

没有要查找的 tbody.

变化:

$('#myTable').find('tbody').remove();

致:

$('#myTable').find('tbody').empty();
