I am trying to make this as simple as possible:
As an example (listed below) I have a javascript ajax call to a java
servlet within my existing Apache Tomcat web application not Drupal.
All that would need to be modified would that the URL have to be the
full path.
Is their a way within Drupal to embed a javascript call similar to the
one listed below?
Thanks,
John
<script type = "text/javascript">
function download(link){
var email = document.getElementById('email');
var xmlHttpReq = new XMLHttpRequest();
var url = 'ecommerce?command=serve&name=' + link + '&email=' +
email.value;
xmlHttpReq.open('post', url, true);
xmlHttpReq.onreadystatechange = function() {
if (xmlHttpReq.readyState != 4) {
return;
}
else {
var responseText = xmlHttpReq.responseText;
return false;
}
}
xmlHttpReq.send(null);
}
</script>
