javascript - AJAX Request with PHP -

-

i'm working on ajax first time , feel i'm close solving problem need help. have webpage file first below, has input field email address. when user submits, ajax dowork() function should called creates request , processes request. have fixed initial issue of request being created i'm positive correct object has been created based on browser. issue there's no response text being submitted , no email created. goal user enter email, introductory email sent address, when successful, response string should submitted letting user know have been added mailing list , submission has worked. help, appreciated. 

<?php include('../includes/educateheader.php');?>  <script type="text/javascript" charset="utf-8" src="ajax.js"></script>  <div class="involve"> <h1>how involved in oec</h1> <span>want become more involved in operation:educate children , don't know how? share email address us, our facebook page, or check out blog out learn more how can join , children obtain education deserve</span><br></br> <form method="get">     email: <input type="email" name="email" id="email" required><br></br>     <input type="submit" value="send" onclick="dowork()"> </form> </div>  <div id="outputresponse"> </div>   <?php include('../includes/educatefooter.php');?>

so here ajax.js file creates request , prints out data recieved email.php file

function gethttpobject() {     if (window.activexobject) {         return new activexobject("microsoft.xmlhttp");     }     else if (window.xmlhttprequest) {         return new xmlhttprequest();     }     else {         alert("your browser not support ajax.");         return null;     } }  function setoutput() {     if (httpobject.readystate == 4 && httpobject.status == 200) {         document.getelementbyid('outputresponse').value = httpobject.responsetext;     } }  function dowork() {     httpobject = gethttpobject();     if (httpobject != null) {         httpobject.open("get", "email.php?email=" + document.getelementbyid('email').value, true);         httpobject.send(null);         httpobject.onreadystatechange = setoutput;     } }  var httpobject = null;

lastly here email.php script should accept ajax request , echo whether success has occurred or not.

<?php if (isset($_get['email'])) {     $mail = trim($_get['email']);     $subject = 'welcome!';     $message = 'thank joining operation:educate children email list.  in future, send updates new opportunities become more involved in activities run here @ oec , make difference on children\'s futures. thank , best wishes!';     mail($mail, $subject, $message);     echo 'success! thank interest in operaton:educate children. stay tuned updates!'; } ?>

first add return false; @ end of function dowork , change onclick="dowork()" onclick="return dowork()"

then change below line 

document.getelementbyid('outputresponse').value = httpobject.responsetext;

to

document.getelementbyid('outputresponse').innerhtml = httpobject.responsetext;

read question :) setting innerhtml vs. setting value javascript
