PHP function + Jquery + Ajax

Question

I cant make it work. I have a php script on a website (not so good in php, so if something is wrong, please point me). And i want to call it from a js document.

<?php
    function doit($option){
        if ('getit' == $option){
            $value = '318273918739182739179';
            return $value;
        }else{
            return 0;
        }
    }
?>

and i want to call it from a js file. How do i pass an argument to the php script via Ajax?

var getanswer ={
php: function(){
    $.ajax({
           url:'mywebsite.com/php/return.php',
           data: {action, 'doit'},
           type: 'post',
           success: function(output){
           alert(output);
           }
           })
}
}

I hate how people on stackoverflow make you feel like a complete crap for asking for help. No, i dont want to run php inside js. I am aware that it s not possible. Sorry — ghaschel

@ghaschel, maybe you should search around a bit before asking how to use AJAX. There are plenty of tutorials online, and we've seen this question asked more than enough already. Heck, you're already passing data to your php, so there isn't even really a question: data: {action, 'doit'}, — Cerbrus

in javascript:

$.get('yourPHPscript.php?argument='+some_arg,function(data){
 //data contain result from php script
});

in yourPHPscript:

$option = $_GET['argument'];
if ('getit' == $option){
        $value = '318273918739182739179';
        echo $value;
    }else{
        echo "0";
    }

You can use ajax to call php whenever you need it

for example I have used it for calling a function glob in php

here is some of the jquery code

$('#search_query').keyup(function() {
    var search_input = $("#search_query");
    var output = search_input.val();
    if(output.length > 0){
    $('#app_menu').hide();
    $('#note').show(1000);
        $.ajax({
                type: "POST",
                url: "search_node.php",
                data:{item:output}
            }).done(function( msg ) {
                if(msg!='error')
                {
                    $("div#note").html(msg);
                }
                else
                {

                    $("#debug").append("<br />refresh function failed: ");
                    $("#debug").scrollTop("30");
                }
            });//ajax 

        }
        if  (output.length  == 0){
        $('#note').hide();
        $('#app_menu').show(250);

        }
    });

});

There are some extra stuf in this code that you might not need, hope this helps

what if you have more than 1 function inside the script? How and where do you specify the function you want to call?

@ghaschel do you mean js script or php
