I have an HTML form that currently just posts the data directly to a PHP file. I want to update the code so that the submit button sends the data to a JavaScript function so that I can create an AJAX function. Is it possible for the submit button to activate a JavaScript function rather than posting to a php file? The only thing I have come up with is below, which quite obviously does not work:
<html>
<head>
<script type="text/javascript">
function ajax(){
//...
}
</script>
</head>
<body>
<form action="ajax();">
<!-- ... -->
<input type="submit" value="Submit" />
</form>
</body>
</html>
