使用C＃从表格单元格内的输入框中提取数据(Extracting Data out of a input box inside a table cell using C#)

我有一些看起来像这样的表：

现在，我想从中删除数据并将其存储在XML文件中。问题是行数未知。用户可以创建3到n行之间的任何位置。为了解决这个问题，我写了一个小循环，将数据逐行拉出来。

// Assume the relevant items are declared and assigned a proper value. while (i < myTable.Rows.Count) { tRow = myTable.Rows[i]; tNameNode.InnerText = tRow.Cells[0].InnerText; tUnitsNode.InnerText = tRow.Cells[1].InnerText; tValueNode.InnerText = tRow.Cells[2].InnerText; tNewEntryNode.AppendChild(tNameNode); tNewEntryNode.AppendChild(tUnitsNode); tNewEntryNode.AppendChild(tValueNode); tIntermediateNode.AppendChild(tNewEntryNode); i++; }

现在我在运行之后才意识到的问题是它不会取出输入框内的内容，只是实际的输入框代码，这不是我想要的。

如何获取输入框内的内容？

I have some table that looks like this:

Now, I want to rip data out of that and store it in an XML file. The problem is that the number of rows is unknown. A user can create anywhere between 3 and n rows. To solve this, I wrote a little loop that pulls data out of the table by row.

// Assume the relevant items are declared and assigned a proper value. while (i < myTable.Rows.Count) { tRow = myTable.Rows[i]; tNameNode.InnerText = tRow.Cells[0].InnerText; tUnitsNode.InnerText = tRow.Cells[1].InnerText; tValueNode.InnerText = tRow.Cells[2].InnerText; tNewEntryNode.AppendChild(tNameNode); tNewEntryNode.AppendChild(tUnitsNode); tNewEntryNode.AppendChild(tValueNode); tIntermediateNode.AppendChild(tNewEntryNode); i++; }

Now the problem with this that I realized only after I ran it is that it's not going to fetch what is inside the input box, just the actual input box code, which is not really what I want.

How can I get the content inside the Input boxes?

您可以开发一些脚本来获取生成的文本框的所有文本值，方法是为它们分配所有相同的ID，然后让脚本按ID获取值。然后将其存储到您可以在C＃代码中访问的变量中

您的文本框的HTML，包括一个隐藏的TextBox，可以使用脚本填充其余文本框的值：

此时对JQuery的个人偏好（但我很确定你可以用任何脚本完成类似的事情）：

$('body').live('input','.userTxtBox', function () { $('#hiddenTxtBox').val($('.userTxtBox').val()); });

然后，在您的C＃代码中，您可以从hiddenTxtBox中获取文本。

The solution I employed looked like this:

while (i < myTable.Rows.Count) { tRow = tblCropsAndFeed.Rows[i]; string tInputBox0 = tRow.Cells[0].Controls[0].ClientID; tContent = (HtmlInputText)tRow.FindControl(tInputBox0); tNameNode.InnerText = tContent.Value; string tInputBox1 = tRow.Cells[1].Controls[0].ClientID; tContent = (HtmlInputText)tRow.FindControl(tInputBox1); tUnitsNode.InnerText = tContent.Value; string tInputBox2 = tRow.Cells[2].Controls[0].ClientID; tContent = (HtmlInputText)tRow.FindControl(tInputBox2); tValueNode.InnerText = tContent.Value; tNewEntryNode.AppendChild(tNameNode); tNewEntryNode.AppendChild(tUnitsNode); tNewEntryNode.AppendChild(tValueNode); tCropsAndFeedNode.AppendChild(tNewEntryNode); i++; }

The huge problem I encountered was the C# was treating the input boxes as a DirectControl object, which made it pretty impossible to get anything out of it. After adding

runat="server"

To the input boxes, all was fine however.
