Question

I am trying to submit a form to execute a php script. But the submit button is not working. It doesn’t seem like I’m missing any quotes or expressions. What may be the problem I am doing wrong?

<script type="text/javascript">

function doSubmit()
{

<?php
echo "Hello";
?>
var actions = document.frm.actions.value;
var tables = document.frm.tables.value;
var text0 = document.frm.text0.value;
var text1 = document.frm.text1.value;
var text2 = document.frm.text2.value;

/*var txtBox = document.getElementById("text3");

if (txtBox!=null){
var text3 = document.frm.text3.value;
var strURL = "devicesql.php?actions=" +actions+ "&tables=" +tables+ "&text0=" +text0+     "&text1=" +text1+ "&text2=" +text2+ "&text3=" +text3;
}

else
{*/
var strURL = "devicesql.php?actions=" +actions+ "&tables=" +tables+ "&text0=" +text0+ "&text1=" +text1+ "&text2=" +text2;
//}

var xmlhttp;

if (str=="")
  {
  document.getElementById("result").innerHTML="";
  return;
  }
if (window.XMLHttpRequest)
  {
  xmlhttp=new XMLHttpRequest();
  }
else
  {
  xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
  }
xmlhttp.onreadystatechange=function()
  {
  if (xmlhttp.readyState==4 && xmlhttp.status==200)
{
document.getElementById("result").innerHTML=xmlhttp.responseText;
}
  }

xmlhttp.open("GET",strURL,true);
xmlhttp.send(null);

}

</script>

Answer 1

Try to create another form for the table displaying the database information. Your form might be confused with the 2 buttons.
