[英]How to make a counter in a table in asp.net mvc
Hello, good afternoon.你好,下午好。 I am making a view in Razor ASP.NET 6. I find myself making a table and what I want to do is in the column N° add a counter, that for each row it creates, I add 1,2,3,4,5, etc. Try to do it with a for, foreach, but it is returning something that does not interest me, or it returns the total value of the rows.
我在 Razor ASP.NET 中创建一个视图 6. 我发现自己创建了一个表,我想做的是在 N° 列中添加一个计数器,对于它创建的每一行,我添加 1,2,3,4,5等。尝试用 for、foreach 来做,但它返回的是我不感兴趣的东西,或者它返回行的总值。 And what I need is to add 1. I'm going to leave an example image.
而我需要的是加 1。我将留下一个示例图像。 I would be very grateful if someone can help me.
如果有人能帮助我,我将不胜感激。 Thanks.
谢谢。
@model Taller.Model.Entities.Remito
@{
var counter = @Model.RemitoDetalle.Count();

<!-- Tabla -->
<div class="table">
<table style="width: 100%">
<tr>
<th style="text-align: left">N°</th>
<th>Detalle</th>
<th style="text-align: left">Cantidad</th>
<th style="text-align: left">Alto</th>

<tbody>
@foreach (var item in Model.RemitoDetalle)
{
<tr>
@for (var i = 1; i < counter; i++)
{
<td>@i</td>
}
<td>@Html.DisplayFor(modelItem => item.PresupuestoDetalle.Descripcion)
</td>
<td>@Html.DisplayFor(modelItem => item.PresupuestoDetalle.Cantidad)</td>
<td>@Html.DisplayFor(modelItem => item.PresupuestoDetalle.Alto)</td>
<td>@Html.DisplayFor(modelItem => item.PresupuestoDetalle.Ancho)</td>
</tr>
}
</tbody>
</table>
</div>
You're going over all possible values of the counter for every row.您将遍历每一行的计数器的所有可能值。 You should only increment it once per row, like this:
您应该每行只增加一次,如下所示:
<tbody>
@int i = 0;
@foreach (var item in Model.RemitoDetalle)
{
i++;
<tr>
<td>@i</td>
<td>@Html.DisplayFor(modelItem => item.PresupuestoDetalle.Descripcion)
</td>
<td>@Html.DisplayFor(modelItem => item.PresupuestoDetalle.Cantidad)</td>
<td>@Html.DisplayFor(modelItem => item.PresupuestoDetalle.Alto)</td>
<td>@Html.DisplayFor(modelItem => item.PresupuestoDetalle.Ancho)</td>
</tr>
}
</tbody>
Try this:尝试这个:
<tbody>
@for (var i = 0; i < Model.RemitoDetalle.Count(); i++)
{
<tr>
<td>@i</td>
<td>
@Html.DisplayFor(model => model.RemitoDetalle[i].PresupuestoDetalle.Descripcion)
</td>
<td>@Html.DisplayFor(model => model.RemitoDetalle[i].PresupuestoDetalle.Cantidad)</td>
<td>@Html.DisplayFor(model => model.RemitoDetalle[i].PresupuestoDetalle.Alto)</td>
<td>@Html.DisplayFor(model => model.RemitoDetalle[i].PresupuestoDetalle.Ancho)</td>
</tr>
}
</tbody>
Replace代替
@for (var i = 1; i < counter; i++)
{
<td>@i</td>
}
by经过
<td>@(++counter)</td>
And on begin of the view or another code line before using it:在使用它之前,在视图或其他代码行的开头:
@{
var counter = 0;
}
