问题描述
隐藏我之前添加到表格单元格的多个按钮。是否可以使用单个按钮控件依次使其可见?我怎样才能用 c# 做到这一点?
网络上有布局、html、css 等教育内容,但我找不到与我想做的事情相关的任何内容。我怎么解决这个问题?
解决方法
如果你想用c#来做,当点击添加按钮时,你需要将你想传递的数据传递给action。这是一个演示:
视图(TestTable.cshtml):
<table>
<thead>
<tr>
<th>1</th>
<th>2</th>
<th>3</th>
<th>4</th>
<th>5</th>
</tr>
</thead>
<tbody>
@if (Model.Amount > 0)
{
var count = 0;
@for (var i = 0; i < Model.Amount / 5 + 1; i++)
{
<tr>
@for (var j = 0; j < 5; j++)
{
count++;
if (count <=Model.Amount&&count<=Model.Buttons.Count)
{
<th><button>@Model.Buttons[5 * i + j]</button></th>
}
else
{
break;
}
}
</tr>
}
}
</tbody>
</table>
<form method="post">
<input hidden name="Amount" value="@Model.Amount">
<input hidden name="Add" value="1">
<button>Add</button>
</form>
操作:
public IActionResult TestTable(TableModel t)
{
List<string> l = new List<string> { "b0","b1","b2","b3","b4","b5" };
TableModel table = new TableModel { Buttons = l,Amount=0,Add=0};
if (t.Add == 1 && t.Amount >= 0) {
table.Amount = ++t.Amount;
}
return View(table);
}
型号:
public class TableModel {
public List<string> Buttons { get; set; }
public int Amount { get; set; }
public int Add { get; set; }
}
