js获取gridview模板列中textbox行列的值
下面一个例子:在gridview中第一列输入数值,第二列输入数值,点击第三列的时候进行计算 求和,如果不符合标记为红色字体。
如图:
代码 :
<html xmlns="http://www.w3.org/1999/xhtml"><head runat="server"> <title></title> <script type="text/javascript"> function setClf(con) { var table = document.getElementById("GridView1"); var tr = table.getElementsByTagName("tr"); //获取鼠标点击的元素 var e = event.srcElement; //获取元素所在的行的行号(表头行号从0开始)。注意:parentElement只适用于IE浏览器,而parentNode则符合DOM标准。 //var rowIndex=e.parentElement.parentElement.rowIndex ; var i = e.parentNode.parentNode.rowIndex; //获取GridView控件 分别获取选定行指定列的值 var a, b,c; a = parseFloat(tr[i].getElementsByTagName("td")[0].getElementsByTagName("input")[0].value); b = parseFloat(tr[i].getElementsByTagName("td")[1].getElementsByTagName("input")[0].value); //上面为获取gridview中textbox的,如果为lable则如下写法 // b = parseFloat(tr[i].getElementsByTagName("td")[1].getElementsByTagName("span")[0].innerText); sum1 = a+b; //计算方法改变 c = parseFloat(tr[i].getElementsByTagName("td")[2].getElementsByTagName("input")[0].value); if (sum1 != c) { con.style.color = "Red"; } else con.style.color = "black"; } </script></head><body> <form id="form1" runat="server"> <div> <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" CellPadding="4" Width="100%" BackColor="White" BorderStyle="Solid" BorderWidth="1px" O> <Columns> <asp:TemplateField HeaderText="数据1"> <ItemStyle HorizontalAlign="Center" VerticalAlign="Middle" /> <ItemTemplate> <asp:TextBox ID="txt_bndy" runat="server" CssClass="tboxSearch_x" Width="50" Height="20" Text=‘<%# Eval("BNDY").ToString() %>‘ /> </ItemTemplate> <HeaderStyle HorizontalAlign="Center" VerticalAlign="Middle" /> <ItemStyle HorizontalAlign="Center" VerticalAlign="Middle" /> </asp:TemplateField> <asp:TemplateField HeaderText="数据2"> <ItemStyle HorizontalAlign="Center" VerticalAlign="Middle" /> <ItemTemplate> <asp:TextBox ID="txt_bndj" runat="server" CssClass="tboxSearch_x" Width="50" Height="20" Text=‘<%# Eval("BNDJ").ToString()%>‘ /> </ItemTemplate> <HeaderStyle HorizontalAlign="Center" VerticalAlign="Middle" /> <ItemStyle HorizontalAlign="Center" VerticalAlign="Middle" /> </asp:TemplateField> <asp:TemplateField HeaderText="求和"> <ItemStyle HorizontalAlign="Center" VerticalAlign="Middle" /> <ItemTemplate> <asp:TextBox ID="txt_bnlj" runat="server" CssClass="tboxSearch_x" Width="50" Height="20" Text=‘<%# Eval("BNLJ").ToString()%>‘ onBlur="setClf(this)" /> </ItemTemplate> <HeaderStyle HorizontalAlign="Center" VerticalAlign="Middle" /> <ItemStyle HorizontalAlign="Center" VerticalAlign="Middle" /> </asp:TemplateField> </Columns> <FooterStyle BackColor="#CCCC99" /> <PagerStyle BackColor="#F7F7DE" ForeColor="Black" HorizontalAlign="Right" /> <SelectedRowStyle BackColor="#CE5D5A" Font-Bold="True" ForeColor="White" /> <AlternatingRowStyle BackColor="White" /> </asp:GridView> </div> </form></body></html>
后台:
protected void Page_Load(object sender, EventArgs e) { DataTable newdtb = new DataTable(); newdtb.Columns.Add("BNDJ"); newdtb.Columns.Add("BNDY"); newdtb.Columns.Add("BNLJ"); for (int i = 1; i < 11; i++) { DataRow newRow = newdtb.NewRow(); //newRow["BNDJ"] = "pro" + i.ToString(); //newRow["BNDY"] = 12.3m; newdtb.Rows.Add(newRow); } GridView1.DataSource = newdtb; GridView1.DataBind(); }
