I have a an HTML button where I want the onclick to call a PHP function. I need to use AJAX to do this but I am totally lost. There is more that occurs inside the php function, but I didn't see the need of including it. Below is code thus far:
<HTML>
<BODY>
<FORM>
<input text="text" name=airport1 id=airport1 />
<input text="text" name=airport2 id=airport2 />
<input type="button" value="Enter" onclick=PrintDist()/>
</FORM>
</BODY>
</HTML>
<?php
function PrintDist(){
$icao1 = $_REQUEST["airport1"];
$icao2 = $_REQUEST["airport2"];
}
?>

Using jQuery (untested):
function PrintDist() { var submitButton = $(this).find('*:submit'); $.post(this.action, $(this).serialize(), function() { alert('Form submitted!'); submitButton.attr('disabled', 'false').attr('value', 'Enter'); }); submitButton.attr('disabled', 'true').attr('value', 'Posting...'); return false; }Use a proper form as your HTML (for people without Javascript, and for the script to work nicely):
<form action="xxx" method="post" onsubmit="return PrintDist()"> <input text="text" name="airport1" id="airport1" /> <input text="text" name="airport2" id="airport2" /> <input type="submit" value="Enter" /> </form> -
Use any javascript library to make ajax calls to the php script on the server. For example:
Or if you just want really simple stuff, take a look at the sajax ajax toolkit for php

nice peace of code but how would you pass a function parameter
<input type="button" value="Enter" onclick=PrintDist(30)/>function PrintDist($value){ foo else bar }
