我正在 div 标签内创建动态表。在每个单元格内部，添加了一个标签和图像按钮。单元格被添加到行和行到表。我想知道如何找到使用 jquery 单击了 5*8 表中的哪个图像按钮。动态表代码添加在asp.net
public void DisplaySeatLayout()
{
//fetching data from database
_seatBUS = new SeatBUS();
DataTable dt = _seatBUS.GetAllSeatByBusRouter(_listBus);
//Layout generation code
ImageButton img ;
HtmlTable table = new HtmlTable();
table.Attributes.Add("runat", "server");
table.Attributes.Add("id", "LayoutTable");
HtmlTableRow [] tr = new HtmlTableRow[] { new HtmlTableRow(), new HtmlTableRow(), new HtmlTableRow(),new HtmlTableRow(),new HtmlTableRow()};
HtmlTableCell tc = null;
int SeatNo=0;
//Getting Total no of seats.
int MaxSeatNo = dt.Rows.Count;
//Iterating datatable
//Displaying labels for displaying column names in the table
for (int columnCounter = 0; columnCounter < 8; columnCounter++){
for (int rowCounter = 0; rowCounter < 5; rowCounter++){
if (SeatNo < MaxSeatNo){
if (rowCounter == 2 && columnCounter < 7){
//adding label in each cell.
tc = new HtmlTableCell();
Label lbl = new Label();
lbl.Text = "";
lbl.ID = "lbl " + rowCounter.ToString() + columnCounter.ToString();
tc.Controls.Add(lbl);
tr[rowCounter].Controls.Add(tc);
}
else{
//adding label in each cell.
tc = new HtmlTableCell();
Label lbl = new Label();
lbl.Text = dt.Rows[SeatNo]["NumberSeat"].ToString();
lbl.ID = "lbl " + rowCounter.ToString() + columnCounter.ToString();
lbl.Attributes.Add("runat", "server");
tc.Controls.Add(lbl);
//adding imagebutton in each cell .
img = new ImageButton();
img.Attributes.Add("runat", "server");
img.Attributes.Add("type", "image");
img.Attributes.Add("id", dt.Rows[SeatNo]["NumberSeat"].ToString());
img.CssClass = "seatRightMostRow1";
img.ImageUrl = "../Images/available_seat_img.png";
img.ID = dt.Rows[SeatNo]["NumberSeat"].ToString();
img.Click += new ImageClickEventHandler(Imagebutton_Click);
tc.Controls.Add(img);
tr[rowCounter].Controls.Add(tc);
SeatNo++;
}
}//SeatNo < MaxSeatNo
table.Controls.Add(tr[rowCounter]);

seatArranngement.Controls.Add(table);
