Question

我必须创建一个可以在单击按钮后动态添加行的表单，下面是代码。所以基本上我想在点击下一行的id="ADD"按钮后用btAdd克隆行。

我不知道在追加功能中添加什么？我尝试过一些东西，但它没有用。提前谢谢。

$(document).ready(function(){
    $("#btAdd").click(function(){
        $("#ADD").append(" ");
    });
});

    </script>
</head>
<body>
    <h1></h1>
    <div id = "myDiv">
        <form name="form1">
            <table border='1' width='700' align="center" cellpadding='5' cellspacing='10'>
                <tr>
                    <th>Place configuration here</th>
                </tr>
                <tr>
                    <td>Server Url: <input type="text" name="surl" id="surl"></td>
                </tr>
                <tr>
                    <td>            
                        Filter Name: <input type="text" name="fname"id="fname">
                        Filter Type
                        <select name="operation">
                            <option value="text">Text</option>
                            <option value = "List">List</option>
                        </select>
                    </td>
                </tr>
                <tr id="ADD">
                    <td>
                        Filter Options: <input type="text" name="foptions"id="foptions">
                        <input type="button" name="ADDb" value="+" id="btAdd">
                    </td>
                </tr>
                <tr>
                    <td>
                        Filter Label: <input type="button" name="filterb" id="filterb" value="Add Filter" onclick="showData();">
                    </td>
                </tr>
                <tr>
                    <td><input type="button" name="submitb" id="submitb" value="Submit"></td>
                </tr>
            </table>
        </form>
    </div>
</body>

Answer 1

试一试：

$("#btAdd").click(function(){
    $("#ADD").clone().removeAttr("id").insertAfter("#ADD");
});

Answer 2

试试这个

$("#btAdd").click(function(){
  $("#ADD").clone().attr("id","ADD_"+$("#table1 tbody").children("tr").length).insertAfter("#ADD");   
});

其中table1是表id。
