js获取gridview的值

js获取gridview的值

方法一:

这是在GridView里面没有控件的情况下,有控件另当别论

var gdview=<%=gridview.ClientID%>;//gridview是GridView控件的ID

或者

var gdview=document.getElementById("<%=gridview.ClientID %>");

//1 读取指定行单元格的值如果是0则读出其表头的值
//rowIndex=1就是第一行的值
function getCellValueByRow(rowIndex)
{
   for(var i=0;i<gdview.rows(rowIndex).cells.length;i++)
   {
      alert(gdview.rows(rowIndex).cells(i).innerText);//弹出指定行单元格的值

   }
}


//2 读取指定列单元格的值 cellIndex=0则为第一列的值
function getValueByCell(cellIndex)
{
   for(var i=0;i<gdview.rows.length;i++)
   {
      alert(gdview.rows(i).cells(cellIndex).innerText);//指定列单元格的值
   }
}

//3 读取所有单元格的值
function getValueAll(cellIndex)
{
   for(var i=1;i<gdview.rows.length;i++)//要从1开始,从0则会读出表头的值
   {
       for(varj=0;j<gdview.rows(i).cells.length;j++)
       {
          alert(gdview.rows(i).cells(j).innerText);//读取所有单元格的值
        }
   }
}


//4 读取列标头的值
functioin getValueTitle()
{
   for(var i=0;i<gdview.rows(0).cells.length;i++)
   {
      alert(gdview.rows(0).cells(i).innerText);//读取列标头的值

   }
}

方法二:

首先在模板列中添加一个按钮用来选中行，页面有关代码如下：

<asp:GridView ID="gdview" runat="server" CellPadding="4"ForeColor="#333333" GridLines="None"
                                           Height="176px" Width="380px"OnRowDataBound="gdview_RowDataBound"OnSelectedIndexChanging="gdview_SelectedIndexChanging">
                                           <FooterStyle BackColor="#1C5E55" Font-Bold="True"ForeColor="White" />
                                           <RowStyle BackColor="#E3EAEB" />
                                           <PagerStyle BackColor="#666666" ForeColor="White"HorizontalAlign="Center" />
                                           <SelectedRowStyle BackColor="#C5BBAF" Font-Bold="True"ForeColor="#333333" />
                                           <HeaderStyle BackColor="#1C5E55" Font-Bold="True"ForeColor="White" />
                                           <EditRowStyle BackColor="#7C6F57" />
                                           <AlternatingRowStyle BackColor="White" />
                                           <Columns>
                                               <asp:TemplateField>
                                                   <ItemTemplate>
                                                       <input id="btnLocation" type="button" value="定位到"onclick="Select()" style="height: 20px" />
                                                   </ItemTemplate>
                                               </asp:TemplateField>
                                           </Columns>
                                       </asp:GridView>

脚本代码如下：

//取得gridview中获取选中行指定列的值
      function Select()
      {
            //获取鼠标点击的元素
            vare=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。
           //varrowIndex=e.parentElement.parentElement.rowIndex ;
            varrowIndex=e.parentNode.parentNode.rowIndex ;
            //获取GridView控件
            vargdview=document.getElementById("<%=gdview.ClientID %>");
           //分别获取选定行标注点的X、Y坐标
           varvalue=gdview.rows(rowIndex).cells(列号).innerText;

      }

方法三:

<scripttype="text/javascript">      function fun()      {           varGridView=document.getElementById("GridView1");          for(var i=1;i <GridView.rows.length;i++)//从1开始，表示不考虑表格列头          {              varhtml=GridView.rows[i].cells[0].getElementsByTagName("input")[0].value;              alert(html);          }       }     </scr
