Question

我有一个表，每行包含4个单元格，每个单元格包含一个文本框默认情况下。我只有一行和一个按钮，每次点击时我都可以添加一行。

如何在Javascript中动态添加包含文本框的表行？

我还希望他们的文本框ID更改：

<input type="text" id="txtbox1" />
<input type="text" id="txtbox2" />

现在，我有添加单元格的代码：

JavaScript的：

<script type="text/javascript">
    function insertRow(){
                var table=document.getElementById("tbSibling");
                var row=table.insertRow(2);
                var cell1=row.insertCell(0);
                var cell2=row.insertCell(1);
                var cell3=row.insertCell(2);
                var cell4=row.insertCell(3);
    }
</script>

表：

<table id="myTable">
        <th>Name</th>
        <th>Age</th>
        <th>Gender</th>
        <th>Occupation and Employer</th>
        <th>Add</th>
        <tr>
            <td><input type="text" id="txtName" /></td>
            <td><input type="text" id="txtAge" /></td>
            <td><input type="text" id="txtGender" /></td>
            <td><input type="text" id="txtOccupation" /></td>
            <td id="btnAdd" class="button-add" onclick="insertRow();">add</td>
        </tr>
</table>

Answer 1

使用纯javascript检查，这是你想要的一切。 JSFIDDLE

var index = 1;
function insertRow(){
            var table=document.getElementById("myTable");
            var row=table.insertRow(table.rows.length);
            var cell1=row.insertCell(0);
            var t1=document.createElement("input");
                t1.id = "txtName"+index;
                cell1.appendChild(t1);
            var cell2=row.insertCell(1);
            var t2=document.createElement("input");
                t2.id = "txtAge"+index;
                cell2.appendChild(t2);
            var cell3=row.insertCell(2);
            var t3=document.createElement("input");
                t3.id = "txtGender"+index;
                cell3.appendChild(t3);
            var cell4=row.insertCell(3);
            var t4=document.createElement("input");
                t4.id = "txtOccupation"+index;
                cell4.appendChild(t4);
      index++;

}

Answer 2

这是 FIDDLE

    var ctr = 1;
$('#myTable').on('click', '.button-add', function () {
    ctr++;
    var txtName = "txtName" + ctr;
    var txtAge = "txtAge" + ctr;
    var txtGender = "txtGender" + ctr;
    var txtOccupation = "txtOccupation" + ctr;
    var newTr = '<tr><td><input type="text" id=' + txtName + ' /></td><td><input type="text" id=' + txtAge + ' /></td><td><input type="text" id=' + txtGender + ' /></td><td><input type="text" id=' + txtOccupation + ' /></td><td id="btnAdd" class="button-add">Add</td></tr>';
    $('#myTable').append(newTr);
});

Answer 3

只需创建一个带有文本框代码的html代码，然后将其附加到元素

上

$("#addRow").click(function(){
   $("#myTable").append("<tr><td>row</td><td><input type='text'></td></tr>");
});

您的工作代码http://jsfiddle.net/WNDQJ/1/

Answer 4

这是一个快速解决方案：

$('#btnAdd').click(function(e) {
    $('#myTable tr:last').after(
        '<tr><td><input type="text" id="txtName' + $("tr:last")[0].rowIndex + '" /></td><td><input type="text" id="txtAge' + $("tr:last")[0].rowIndex + '" /></td><td><input type="text" id="txtGender' + $("tr:last")[0].rowIndex + '" /></td><td><input type="text" id="txtOccupation' + $("tr:last")[0].rowIndex + '" /></td></tr>'
    );
});

另外，我建议你只有一个添加按钮。除非您需要，否则您不需要复制添加按钮。
