我有一个JSON对象，其中包含许多客户端，每个客户端我有几个月的时间，并在该月的某些日期范围内付款。
我正在尝试遍历此客户列表以显示每个客户的表格，并在此表格中显示该月份的付款。棘手的部分是我需要强调付款的时间与前一时期不同。我的问题是我设法比较同月的付款，但是我没有设法比较当月第一个月的付款与上个月的最后一个月。
这是我的JSON（由遗留系统返回）：

这是我的HTML，我试图循环使用ng-repeat并尝试在付款时使用“突出显示”类与前一个不同：
<table ng-repeat="customer in customersList">
<tbody ng-repeat="month in customer.months">
<tr ng-repeat="detail in customer.details track by $index">
<td data-ng-class="{'highlight' : month.details[$index-1].payment != month.details[$index].payment && $index > 0}">{{::detail.payment}} {{month.details[$index-1].payment != month.details[$index].payment && $index > 0}}</td>
<td data-ng-class="{'highlight' : month.details[$index-1].payment != month.details[$index].payment && $index > 0}">{{::detail.payment | currency}} {{$parent.customers.months[$index].details[$index-1].payment}}</td>
</tr>
</tbody>
</table>
我尝试使用$ parent尝试访问上个月，并能够将上个月的最后一笔付款与新月的第一笔付款进行比较，但却失败了。有人可以告诉我我做错了什么，以及这是否可行？
答案 0 :(得分：0)
您当前的实施失败，因为month.details是customer.months中的索引，您希望索引位于<table ng-repeat="customer in customersList">
<tbody ng-repeat="month in customer.months">
<tr ng-init="monthIndex = $index" ng-repeat="detail in customer.details track by $index">
<td data-ng-class="{'highlight' : customer.months[monthIndex - 1].details[$index].payment != month.details[$index].payment && monthIndex > 0}">
{{::detail.payment}} {{customers.months[monthIndex - 1].details[$index] != month.details[$index].payment && $index > 0}}
</td>
<td data-ng-class="{'highlight' : customer.months[monthIndex - 1].details[$index-1].payment != month.details[$index].payment && monthIndex > 0}">
{{::detail.payment | currency}} {{customers.months[monthIndex - 1].details[$index].payment}}
</td>
</tr>
</tbody>
</table>
。
这是the ng-init directive的目的。
我不是百分之百确定你打算如何比较付款，但我相信你想要这样的东西：
monthIndex这会将month.details设置为进入month.details循环之前的当前月份的索引。此范围变量在monthIndex - 1循环中可用，因此您可以使用create table Dates (
id int identity(1,1) primary key,
dates DateTime Not Null Default(GetDate())
)
查看上个月。
