我为数据库更新编写了代码。问题是添加新行后，它显示然后消失..这个页面在服务器端。我试图在Firefox和chrome中打开该页面，它显示然后消失。问题是什么？？

<head>
    <script type="text/javascript" src="http://code.jquery.com/jquery-latest.min.js"></script>
    <script>
        //$(function() { alert('hi') })
        $(document).ready(
            function () {
                $("#AddRow").click(
                    function () {
                        if ($('.checkbox').is(':checked')) {
                            {
                                //alert('hi') 
                                var row = document.getElementById("row"); // find row to copy
                                var table = document.getElementById("tabletomodify"); // find table to append to
                                var clone = row.cloneNode(true); // copy children too
                                clone.id = "row0"; // change id or other attributes/contents
                                table.appendChild(clone); // add new row to end of table

                            }

                        }
                    }

                );

这是一个老问题，但我最近遇到了类似的问题。原来使用 HTML 标记<button>是问题所在。如果您将按钮放在表单中，它将导致页面重新加载，从而导致您报告的问题。尽管您的表单中没有按钮，但您可能没有准确地向我们发布您页面上的内容？我怀疑是这种情况，因为您的 HTML 中没有正文标记。

最简单的解决方法是< input type="button"/>改用。

这是一个使用相同 html 并清理了 JavaScript 的小提琴：http: //jsfiddle.net/krmFU/

$("#AddRow").click(function () {
    if ($('.checkbox').is(':checked')) {
        {
            alert('hi');
            var row = document.getElementById("row"); // find row to copy
            var table = document.getElementById("tabletomodify"); // find table to append to
            var clone = row.cloneNode(true); // copy children too
            clone.id = "row0"; // change id or other attributes/contents
            table.appendChild(clone); // add new row to end of table
        }
    }
});

<table cellpadding="10" style="border:2px solid black;" id="tabletomodify">
    <tr bgcolor="#360584">
        <td style="border:1px solid black;" colspan="15"><font face="Arial" size="4" color="white"><b><i>Records</i></b></font>

        </td>
    </tr>
    <tr>
