[résolu pour le moment :P] Ajax, aide svp

[V1nc3]

C'est mieux que je fasse un petit résumé de ce que je trouve bizarre :

Code PHP :

<?php 

function createRequestObject()

{

    var http;

    if(window.XMLHttpRequest)

    {

        http = new XMLHttpRequest();

    }

    else if(window.ActiveXObject)

    {

        http = new ActiveXObject("Microsoft.XMLHTTP");

    }

    return http;

} 



function affichage_result()

{

    if(http.readyState == 4)

    {

        if(http.status == 200)

        {

            alert(':)');

        }

        else

        {

            alert(http.status + ' : ' + http.statusText);

        }

    }

}



function bouger(x, y)

{

    http = createRequestObject();

    http.open('post', 'pages/requetes_ajax.php', true);

    http.onreadystatechange = affichage_result();

    http.setRequestHeader("Content-type", "application/x-www-form-urlencoded");

    http.send('data_x='+x+'&data_y='+y);

    location.reload();

    

}



function camoufler()

{

    http = createRequestObject();

    http.open('post', 'pages/requetes_ajax.php', true);

    http.onreadystatechange = affichage_result();

    http.setRequestHeader("Content-type", "application/x-www-form-urlencoded");

    





}
