PHP生成的表单不提交AJAX

Question

I have a select with ROWID in the value and the name in the value,

<select name="opcoes"  onchange="showInfo(this.value)">
<option value=''>Select</option>
<option value=6>A</option>
<option value=2>F</option>
<option value=5>L</option>
<option value=1>M</option>
</select>

when you select one i have this ajax code to create a form with php,

    function showInfo(str)
{


if (str=="")
  {

  document.getElementById("fields").innerHTML="";
  return;
  } 
if (window.XMLHttpRequest)
  {// code for IE7+, Firefox, Chrome, Opera, Safari
  xmlhttp=new XMLHttpRequest();
  }
else
  {// code for IE6, IE5
  xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
  }
xmlhttp.onreadystatechange=function()
  {
  if (xmlhttp.readyState==4 && xmlhttp.status==200)
    {
    document.getElementById("fields").innerHTML=xmlhttp.responseText;
    }
  }
xmlhttp.open("GET","php/vendors/getRow.php?id="+str,true);
xmlhttp.send();
}

Next if the selected value isnt "" it goes to the php,

...conection to the database...

echo "<form action='/php/vendors/edit.php' onSubmit=\"return confirm('Deseja editar?')\" method='post' >"; 
echo "<td><input type='text' name='editname'   value='".utf8_encode($linha[vendor_name])."'    ></td>";
echo "<td><input type='text' name='editemail'    value='".utf8_encode($linha[vendor_email])."'    ></td>";
echo "<td><input type='text' name='editwebsite'    value='".utf8_encode($linha[vendor_website])."'  ></td>";
echo "<td><input type='text' name='editphone'    value='".utf8_encode($linha[vendor_phone])."'    ></td>";
echo "<td><input type='text' name='editfax'     value='".utf8_encode($linha[vendor_fax])."'     ></td>";
echo "<td><input type='text' name='editadress'    value='".utf8_encode($linha[vendor_adress])."'   ></td>";
echo "<td><input type='text' name='editincharge'   value='".utf8_encode($linha[vendor_incharge])."'  ></td>";
echo "<td class='btn'><input class='edit' type='submit' value=''></td>";
echo "</form>";

It displays every information correctly the ONLY problem is that it does not submit when i click the input submit button... any ideas why?

Answer 1

You are generating invalid HTML.

A form can contain an entire table. A table cell can contain an entire row. A form cannot exist inside a table but around a set of cells in that table.

Your browser is error recovering by moving the form to after the table but leaving the form controls behind.

This means that the submit button isn't inside a form so it can't submit a form.
