Ajaxおよび/またはPHPエラー

Question

私はAJAXをPHPと共に使用して、訪問者がページ上で費やした時間を、PHPスクリプトが他の詳細とともにテキストファイルに書き込むサーバーに伝えます。 AJAXスクリプトは、PHPスクリプトを呼び出すことができませんので、訪問者の詳細は。これは、AJAXスクリプト

PHPスクリプトがあまりにも下に与えられたある

<script type="text/javascript"> 
    var startTime = new Date();  //Start the clock! 
    window.onbeforeunload = function()  //When the user leaves the page(closes the window/tab, clicks a link)... 
    { 
     var endTime = new Date();  //Get the current time. 
     var timeSpent = (endTime - startTime);  //Find out how long it's been. 
     var xmlhttp;  //Make a variable for a new ajax request. 
     if (window.XMLHttpRequest)  //If it's a decent browser... 
     { 
      // code for IE7+, Firefox, Chrome, Opera, Safari 
      xmlhttp = new XMLHttpRequest();  //Open a new ajax request. 
     } 
     else  //If it's a bad browser... 
     { 
      // code for IE6, IE5 
      xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");  //Open a different type of ajax call. 
     } 

     xmlhttp.open("GET","ajaxphp.php?time="+timeSpent,false);  //The false at the end tells ajax to use a synchronous call which wont be severed by the user leaving. 
     xmlhttp.send();  //Send the request and don't wait for a response. 
    } 
</script>

以下を試してください：

• ウェブブラウザでurl ajaxphp.php？time = 123456に直接アクセスしてくださいペン
• 使用AJAX呼び出しを活性化し、AJAXのための代わりに
• 使用jqueryのを何が起こるかに注意し、これらのいずれかがより多くのあなたを与えるだろう、私は確信している
