This can be achieved using ajax, lets see an example,
File : index.php<html>
<head>
<title>Example</title>
<script>
$('.myButton').click(function() {
$.ajax({
type: "POST",
url: "phpFileWithFunction.php"
}).done(function( resp ) {
alert( "Hello! " + resp );
});
});
</script>
</head>
<body>
<input type="button" value="Click" id="myButton" />
</body><?php
class Foo {
function myFunc() {
return "This data is received from PHP function on button click!";
}
}
$fooObj = new Foo();
echo $fooObj->myFunc();
