主题：表格提取数据问题

调试看服务端接收到的值

服务器接收到的列没问题啊，怎么回事？

服务端哪一句代码执行后出错

Dim e As RequestEventArgs = args(0)
Dim wb As New weui
  Dim sb As New StringBuilder
'For Each key As String In e.PostValues.Keys
'            sb.AppendLine(key & ":" & e.PostValues(key) & "<br/>")
'        Next
'        e.WriteString(sb.ToString)
 MessageBox.Show("1")
If e.GetValues.ContainsKey("sureyidtimes") Then
    If e.GetValues.ContainsKey("key") Then
        Dim pr As DataRow = DataTables("压舱水").SQLFind("[_Identify] =" & e.getvalues("key"))
        If pr IsNot Nothing Then
            Dim nms() As String = {"tankno", "obvd", "correct", "tovcubmeter", "density"}
            For Each nm As String In nms
                pr(nm) = e.PostValues(nm)
            Next
             MessageBox.Show("2")
            '计算结果
            If pr.IsNull("obvd") And pr.IsNull("correct") Then
                pr("corrd") = Nothing
            Else
                pr("corrd") = Math.Round(pr("obvd") + pr("correct") / 100, 2)
            End If
            '' "tovcubmeter","density"  ''weightmetricton,操作表bw获取公式
            If pr.IsNull("tovcubmeter") Or pr.IsNull("density") Then
                pr("weightmetricton") = Nothing
            Else
                pr("weightmetricton") = Math.Round(pr("tovcubmeter") * pr("density"), 2)
            End If
             MessageBox.Show("3")
            pr.Save()
            DataTables("压舱水").Load
             MessageBox.Show("4")
        Else
            DataTables("压舱水").appendload("[_Identify]=" & e.getvalues("key"))
             MessageBox.Show("5")
        End If

 

显示1，然后报错，然后显示5

大概知道原因了，因为我先点击行，然后修改，传送到后端保存，然后再修改，这个时候就会丢失主键，传送到后端就没有主键了，这个有办法吗？

js文件发上来看看

function setvalues(){
    document.getElementById("tankno").value = table1.rows[table1.rowSel].cells[0].innerHTML; //红色表示选中的行，蓝色表示第一列
    document.getElementById("obvd").value = table1.rows[table1.rowSel].cells[1].innerHTML;
    document.getElementById("correct").value = table1.rows[table1.rowSel].cells[2].innerHTML;
    document.getElementById("tovcubmeter").value = table1.rows[table1.rowSel].cells[3].innerHTML;
    document.getElementById("density").value = table1.rows[table1.rowSel].cells[4].innerHTML;
}

function myfunction1(sureyidtimes){
  if(document.getElementById("tankno").value==''){  //假如舱号为空，则传输srueyidtimes，生成表格
 var result=submitAjaxFileds("list3save.htm?sureyidtimes="+sureyidtimes,"","tankno","obvd", "correct", "tovcubmeter", "density",false)
    document.getElementById("p1").innerHTML=result;
     bindTable();
  }else{                                           //假如舱号不为空，则代表已经进入编辑状态，将传输主键
    var result=submitAjaxFileds("list3save.htm?key=" + table1.primarykey+"&sureyidtimes="+sureyidtimes,"","tankno","obvd", "correct", "tovcubmeter", "density",false)
    document.getElementById("p1").innerHTML=result;
     bindTable(); //必须有此函数，见下，不然无法触控操作
}
 }

 

黄色部分是发送后端编辑存储的

function myfunction1(sureyidtimes){
  if(document.getElementById("tankno").value==''){  //假如舱号为空，则传输srueyidtimes，生成表格
 var result=submitAjaxFileds("list3save.htm?sureyidtimes="+sureyidtimes,"","tankno","obvd", "correct", "tovcubmeter", "density",false)
    document.getElementById("p1").innerHTML=result;
     bindTable();
  }else{                                           //假如舱号不为空，则代表已经进入编辑状态，将传输主键

解决

试试 function myfunction1(sureyidtimes){   if(document.getElementById("tankno").value==''){  //假如舱号为空，则传输srueyidtimes，生成表格  var result=submitAjaxFileds("list3save.htm?sureyidtimes="+sureyidtimes,"","tankno","obvd", "correct", "tovcubmeter", "density",false)     document.getElementById("p1").innerHTML=result;      bindTable();   }else{                                           //假如舱号不为空，则代表已经进入编辑状态，将传输主键 var key = table1.primarykey;     var result=submitAjaxFileds("list3save.htm?key=" + table1.primarykey+"&sureyidtimes="+sureyidtimes,"","tankno","obvd", "correct", "tovcubmeter", "density",false)     document.getElementById("p1").innerHTML=result;      bindTable(); //必须有此函数，见下，不然无法触控操作 table1.primarykey = key  }  } 这个地方，除了返回来一个网页，能否同时再返回一组数组？比如我想接收到服务端函数返回的{"tankno","obvd", "correct", "tovcubmeter", "density"}数组，并直接通过document.getElementById("tankno").value=...这种方式赋值到表单内。这个应该怎样发送和接收？
