当重点放在文本输入字段时，在手机上获取数字键盘

Question

我有一个输入字段，需要是text，text。但我希望手机上出现的键盘是数字键盘。怎么能实现这一目标？我尝试过以下方法：

'dtb is the datatable'
Dim lstMaxLen As New List(Of Integer)
For Each dcl As DataColumn In dtb.Columns
  Dim intMaxLen As Integer = 0
  For Each drw As DataRow In dtb.Rows
    If drw(dcl.ColumnName).ToString.Length > intMaxLen Then
      intMaxLen = drw(dcl.ColumnName).ToString.Length
    End If
  Next drw
  lstMaxLen.Add(intMaxLen)
Next dcl

          "type": "string"
        },
