Javascript生成的表单未提交

使用Javascript生成表单时，我在将表单数据提交到php文件时遇到问题。不太确定如何修复它。它在test.html文件上自行运行，但在javascript生成时不起作用。
因此php看起来是这样的：

function logDisp(){
var divCheck = document.getElementById('logRec');
if (divCheck != null) divCheck.parentNode.removeChild(divCheck);
var getC = document.getElementById("craneDrop");
var vCrane = getC.options[getC.selectedIndex].text;
var getD = document.getElementById("dept");
var vDept = getD.options[getD.selectedIndex].text;
var logDiv = document.createElement("div");
logDiv.setAttribute("id", "logRec");
logDiv.className = "round1";
logDiv.style.marginTop = "10px";
logDiv.style.width = "600px";
logDiv.innerHTML = "<table border=1 width=100% style='margin-top:20px;'>"
+"<form action='submit.php' method='post' name='form1' id='form1'>"
+"<tr><td>Department | <input type=text name=lname value='"+vDept+"' disabled></td><td colspan=2> Crane | <input type=text name=fname value='"+vCrane+"' disabled></td></tr>"

+"</table>"
+"Member number:<BR><input type=text name=member><BR>"
+"Date:<BR><input type=text name=inputDate value="+dateIn()+"><BR>"
+"<BR><input type=submit />"
+"</form>";
logDiv.innerHTML += "<BR>";
var getOk = document.getElementById("craneDrop");
var vOk = getOk.options[getOk.selectedIndex].value;
if(vOk != '0') // Check if crane selection is a valid selection
document.getElementById("log").appendChild(logDiv);

}

并在HTML中添加以下内容：

<div id='log' style='padding-bottom: 20px;'></div>

当它在初始页面之后生成时，我如何让它将数据提交到submit.php？？
