Right now I’m struggling to get this simple PHP AJAX request to work.
<html>
<head>
<script type="text/javascript">
function getSuggestions(type){
if(type == "")
{
document.getElementById("entries").innerHTML="test"
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("entries").innerHTML=xmlHttp.response;
}
}
xmlHttp.open("GET","getData.php?status="+type,true);
xmlHttp.send();
}
</script>
</head>
<body>
<div id="A" onclick='getSuggestions("A")'>Click for A</div>
<div id="P" onclick='getSuggestions("P")'>Click for P</div>
<div id="R" onclick='getSuggestions("R")'>Click for R</div>
<div id="entries"></div>
</body>
</html>
Below is getData.php
<?php
$status = $_GET["status"];
echo $status;
?>
Everytime I click on any of the tags I get “undefined” in the “entries” tag. Could anybody explain why it’s undefined?
use xmlHttp.responseText
