我有一个表格,其中每个表格行重复我的日期值。我试图用我的查询中的SQL解决这个问题但是那里不能做到所以我正在寻找其他解决方案用Javascript或JQuery来解决这个问题。所以我想删除日期值,如果它们重复,但如果日期值在我的td中改变,我会保留它。表格如下:
Date Time
10/19/2016 8:00 AM - 8:30 AM
10/19/2016 8:30 AM - 9:00 AM
10/19/2016 9:00 AM - 9:30 AM
10/19/2016 9:30 AM - 10:00 AM
10/19/2016 10:00 AM - 10:30 AM
10/19/2016 10:30 AM - 11:00 AM
10/19/2016 11:00 AM - 11:30 AM
10/19/2016 11:30 AM - 12:00 PM
10/19/2016 12:00 PM - 12:30 PM
10/19/2016 12:30 PM - 1:00 PM
10/19/2016 1:00 PM - 1:30 PM
10/19/2016 1:30 PM - 2:00 PM
10/20/2016 9:00 AM - 9:20 AM
10/20/2016 9:20 AM - 9:40 AM
10/20/2016 9:40 AM - 10:00 AM
10/20/2016 10:00 AM - 10:20 AM
10/20/2016 10:20 AM - 10:40 AM
10/20/2016 10:40 AM - 11:00 AM
10/20/2016 11:00 AM - 11:20 AM
10/20/2016 11:20 AM - 11:40 AM
10/20/2016 11:40 AM - 12:00 PM
10/20/2016 12:00 PM - 12:20 PM
10/20/2016 12:20 PM - 12:40 PM
10/20/2016 12:40 PM - 1:00 PM
10/20/2016 1:00 PM - 1:20 PM
10/20/2016 1:20 PM - 1:40 PM
10/20/2016 1:40 PM - 2:00 PM
10/20/2016 2:00 PM - 2:20 PM
10/20/2016 2:20 PM - 2:40 PM
正如您在上面所看到的,这与每行列出的所有日期非常混淆,我想保留每个日期的第一个日期值。像这样:
Date Time
10/19/2016 8:00 AM - 8:30 AM
8:30 AM - 9:00 AM
9:00 AM - 9:30 AM
9:30 AM - 10:00 AM
10:00 AM - 10:30 AM
10:30 AM - 11:00 AM
11:00 AM - 11:30 AM
11:30 AM - 12:00 PM
12:00 PM - 12:30 PM
12:30 PM - 1:00 PM
1:00 PM - 1:30 PM
1:30 PM - 2:00 PM
10/20/2016 9:00 AM - 9:20 AM
9:20 AM - 9:40 AM
9:40 AM - 10:00 AM
10:00 AM - 10:20 AM
10:20 AM - 10:40 AM
10:40 AM - 11:00 AM
11:00 AM - 11:20 AM
11:20 AM - 11:40 AM
11:40 AM - 12:00 PM
12:00 PM - 12:20 PM
12:20 PM - 12:40 PM
12:40 PM - 1:00 PM
1:00 PM - 1:20 PM
1:20 PM - 1:40 PM
1:40 PM - 2:00 PM
2:00 PM - 2:20 PM
2:20 PM - 2:40 PM
以下是我目前用于向屏幕输出值的代码:
<table>
<thead>
<tr>
<th>Date</th>
<th>Time Slots</th>
</tr>
</thead>
<tbody>
~[tlist_sql;
Select to_char(PTC_DATE,'mm/dd/yyyy'),SLOT_LABEL
From EVENT_SLOTS
Where e.EVENT_ID = '145'
Order by PTC_DATE, DISPLAY_ORDER;]
<tr>
<td>~(PTC_DATE)</td>
<td>~(SLOT_LABEL)</td>
</tr>
[/tlist_sql]
</tbody>
</table>
如果甚至可以删除Date td标记中的重复日期值,会怎样?如果有人可以提供帮助,请告诉我。感谢。

好的,如果你真的想在jquery / javascript中为每个日期<td>
标记添加类,并运行此代码:
var placeholder = '';
$(".date").each(function() {
if (placeholder != '') {
if (placeholder == $(this).text()) {
$(this).text("");
} else {
placeholder = $(this).text();
}
} else {
placeholder = $(this).text();
}
});

您可以使用类似于以下内容的空白更新日期值:
update table1 a
set a.date =''
where a.time > (
select min(time)
from table1
where date=a.date
)
使用增量列进行过滤将完成工作
update table1 a
set a.date =''
where a.ID > (
select min(ID)
from table1
where a.date=date
)
