我正在尝试使用bootstrap和asp.net构建一个在表中添加和删除行的选项。但是,我有动态添加DropDownList的问题。
我的观点:
<body>
<div class="container">
<table id="myTable" class=" table order-list">
<thead>
<tr>
<th>Payment Category</th>
<th>Amount</th>
</tr>
</thead>
<tbody>
<tr>
<td class="col-sm-3">
@Html.DropDownListFor(m => m.SelectedPaymentCategory, Model.PaymentCategories, "Select a Category", new
{
@class = "form-control"
})
</td>
<td class="col-sm-2">
<input type="number" name="amount" class="form-control" />
</td>
<td class="col-sm-2">
<input type="button" class="ibtnDel btn btn-md btn-danger " value="Delete">
</td>
</tr>
</tbody>
<tfoot>
<tr>
<td colspan="3" style="text-align: left;">
<input type="button" class="btn btn-lg btn-block " id="addrow" value="Add Row" />
</td>
</tr>
<tr></tr>
</tfoot>
</table>
</div>
</body>
该模型是获取付款类别的简单查询。 然后,我有一个JS来添加和删除表中的行:
$(document).ready(function () {
var counter = 0;
$("#addrow").on("click", function () {
var newRow = $("<tr>");
var cols = "";
// HERE IS MY ISSUE. HOW CAN I CREATE THE DropDownList
cols += '<td><input type="text" class="form-control" name="name' + counter + '"/></td>';
cols += '<td><input type="number" class="form-control" name="amount' + counter + '"/></td>';
cols += '<td><input type="button" class="ibtnDel btn btn-md btn-danger " value="Delete"></td>';
newRow.append(cols);
$("table.order-list").append(newRow);
counter++;
});
$("table.order-list").on("click", ".ibtnDel", function (event) {
$(this).closest("tr").remove();
counter -= 1
});
});
function calculateRow(row) {
var price = +row.find('input[name^="price"]').val();
}
function calculateGrandTotal() {
var grandTotal = 0;
$("table.order-list").find('input[name^="price"]').each(function () {
grandTotal += +$(this).val();
});
$("#grandtotal").text(grandTotal.toFixed(2));
}
一切正常,但我不知道如何在JS中创建DropDownList。有没有更好的方法呢?

您必须添加select
元素:
cols += '<td><select> \
<option value=“option1”>option1</option> \
<option value=“option2”>option2</option> \
</select></td>';
