            function doOnOrientationChange()
            {
                switch(window.orientation) 
                {  
                    case -90:                 
                        document.getElementById("landscape").style.display="block";
                    break;
                    case 90:              
                        document.getElementById("landscape").style.display="block";

</script>
<body>
 <span id="space" ><input onclick='MakeRequest();' onmouseup="changement()"       type="button" value="PUSH" id="bouton"/></span>
 </body>

compteur.php：

<?php

$clicks = file_get_contents("compteur.txt");
$clicks++;

$fp = fopen("compteur.txt", "w+");

while ( !flock($fp, LOCK_EX) ) {    
    usleep(500000); // Delay half a second
}

fwrite($fp, $clicks);
fclose($fp);
flock($fp, LOCK_UN);

 ?>

当我点击按钮时，一切似乎都有效。控制台中没有错误。 但不是向我显示点击次数，而是显示“未定义”。

感谢您的帮助。

XMLHttpRequest个对象没有名为countText的属性。在MakeRequest中，您需要responseText代替：

HandleResponse(xmlHttp.responseText);
// Not `countText` ----^
