javascript - 迭代动态创建的表并将数据插入 SQL Server 表

Question

我有一个 .html 表单动态创建的表，我想在 .cfm 表单中进行插入。我需要循环遍历动态创建的表的行并对 SQL Server 中的表执行 INSERT。此外，该表是用 JavaScript 创建的。谢谢。

<cfoutput>
 <cfloop from="1" to="#ArrayLen(tblSample)#" index="i">
  <cfquery name="AppendForm" datasource="TestSource">
    INSERT INTO tblGrand
    (GrandNum,
    GrandName, 
    County, 
    VersionType, 
    VersionNum, 
    SectCode, 
    Comments,    
    Provider,       
    TypeID,     
    SubmitDate)                 
    Select
    <cfif isdefined("form.GrandNum")>
      '#GrandNum#',
    <cfelse>
      null,
    </cfif>
    <cfif isdefined("form.GrandNme")>
      '#GrandNme#',
    <cfelse>
      null,
    </cfif>
    <cfif isdefined("form.selCnty")>
      '#selCnty#',
    <cfelse>
      null,
    </cfif>
    <cfif isdefined("form.VersionType")>
      '#VersionType#',
    <cfelse>
      null,
    </cfif>
    <cfif isdefined("form.VersionNum")>
      '#VersionNum#',
    <cfelse>
      null,
    </cfif>
    <cfif isdefined("form.SectCode[i]")>
      '#SectCode[i]#',
    <cfelse>
      null,
    </cfif>
    <cfif isdefined("form.txtComments[i]")>
      '#textComments[i]#',
    <cfelse>
      null,
    </cfif>
    <cfif isdefined("form.txtProvider[i]")>
      '#txtProvider[i]#',
    <cfelse>
      null,
    </cfif>
    <cfif isdefined("form.selType[i]")>
      '#selType[i]#',
    <cfelse>
      null,
    </cfif>
    '#DateFormat(Now(),"yyyy-mm-dd") &" "& TimeFormat(Now(),"HH:mm:ss")#'
    </cfquery>
  </cfloop>

这是我用于创建表的 html 代码:

<script language="javascript" type="text/javascript">
function addRow() {

    var tbl = document.getElementById('tblSample');
    var lastRow = tbl.rows.length;  
    var iteration = lastRow;
    var row = tbl.insertRow(lastRow);

  // left cell
    var cellLeft = row.insertCell(0);
    var textNode = document.createTextNode(iteration-3);
    cellLeft.appendChild(textNode);

      // select cell
    var cellRightSel = row.insertCell(1);
    var sel = document.createElement('select');
    sel.name = 'sectCode' + iteration;
    sel.id = 'sectCode' + iteration;    
    sel.options[0] = new Option('---Any---', '0');
    sel.options[1] = new Option('Level 0.5: test1, '1');
    sel.options[2] = new Option('Level I: test2', '2');
    sel.options[3] = new Option('Level I.D: test3', '3');
    sel.options[4] = new Option('Level II.1: test4', '4');
    sel.options[5] = new Option('Level II.5: test5', '5');
    cellRightSel.appendChild(sel);

    var cellRights = row.insertCell(2);
    var els = document.createElement('input');
    els.type = 'text';
    els.name = 'txtComments' + iteration;
    els.id = 'txtComments' + iteration;
    els.size = 20;
    cellRights.appendChild(els);

    var cellRight = row.insertCell(3);
    var el = document.createElement('input');
    el.type = 'text';
    el.name = 'txtProvider' + iteration;
    el.id = 'txtProvider' + iteration;
    el.size = 20;  
    cellRight.appendChild(el);

    var cell7 = row.insertCell(8);
    var sel5 = document.createElement('select');
    sel5.name = 'selType' + iteration;
    sel5.id = 'selType' + iteration;
    sel5.options[0] = new Option('---Any---', '---Any---');
    sel5.options[1] = new Option('Fees, 'Fees);
    sel5.options[2] = new Option('Reimbursement', 'Reimbursement');
    cell7.appendChild(sel5);
}

您需要使用VALUES插入数据库。您还应该使用 structKeyExists 而不是 isDefined，并且还应该使用 cfqueryparam。我也会调整你的变量的范围。

<cfloop from="1" to="#ArrayLen(tblSample)#" index="i">
  <cfquery name="AppendForm" datasource="TestSource">
  INSERT INTO tblGrand
  (GrandNum,
  GrandName, 
  County, 
  VersionType, 
  VersionNum, 
  SectCode, 
  Comments,      
  Provider,     
  TypeID,       
  SubmitDate) 
  VALUES (
  <cfif structKeyExists(form,"GrandNum")>
    <cfqueryparam cfsqltype="cf_sql_varchar" value="#form.GrandNum#">,
  <cfelse>
    NULL,
  </cfif>
  <cfif structKeyExists(form,"GrandNme")>
    <cfqueryparam cfsqltype="cf_sql_varchar" value="#form.GrandNme#">,
  <cfelse>
    NULL,
  </cfif>
  <cfif structKeyExists(form,"selCnty")>
