我有一张包含4个cols的表:
<table id="myTable">
<th>
<td> A </td>
<td> B </td>
<td> C </td>
<td> D </td>
</th>
<tr>
<td>
<span>A-1</span> <span>A-3</span> <span>A-5</span>
</td>
<td>
<span>B-2</span> <span>B-3</span>
</td>
<td>
<span>C-3</span> <span>C-4</span> <span>C-7</span>
</td>
<td>
<span>D-1</span>
</td>
</tr>
</table>
我有A,B,C和D的下拉列表,带有更改处理程序(A = 1,B = 2等):
@Html.DropDownListFor(model => model.TypeID, new SelectList(Model.Types, "Key", "Value", Model.TypeID))
$('#myTable').change(function () {
var type = $(this).val();
if (type == 1) {
var tr = $('#current tr')[0];
var td = tr.cells[0].innerHTML;
var last = $(td).find(':last-child');
/// how do I get the contents of the last span???
} else if ( type == 2 ) {
...
}
});
最后,一个文本框:
@Html.TextBoxFor(model => model.next)
当用户从下拉列表中选择一个选项时,我想根据appropritate表格单元格中最后一个范围内的内容放置相应的“下一个”值。 我似乎无法弄清楚如何获取最后一个,并提取值。
答案 0 :(得分:1)
$('#myTable').change(function () {
var type = +$(this).val();
if (type === 1) {
var tr = $('#current tr');
var td = tr.find('td:eq(0)');
var last = td.find('span:last');
var contents = last.html();
} else if ( type == 2 ) {
...
}
});
