$ delete_commant = l(t('X'),$ url,array('attributes'=> array('onclick'=>'return call_ajax(123)')));drupal call ajax function

,當我把在call_ajax函數定義警報,它警告,所以我繼續寫的AJAX POST方法,但是當我點擊鏈接頁面得到刷新,

如何在Drupal

實現Ajax
function call_ajax(str){alert(str); 
    var url = "post.php"; 
    var params = "lorem=ipsum&name=binny"; 
    http.open("POST", url, true); 

    //Send the proper header information along with the request 
    http.setRequestHeader("Content-type", "application/x-www-form-urlencoded"); 
    http.setRequestHeader("Content-length", params.length); 
    http.setRequestHeader("Connection", "close"); 

    http.onreadystatechange = function() {//Call a function when the state changes. 
     if(http.readyState == 4 && http.status == 200) { 
      alert(http.responseText); 
     } 
    } 
    http.send(params); 
    }

你嘗試初始化在這個例子中看起來他們正在初始化var xmlhttp; http://www.w3schools.com/ajax/ajax_aspphp .asp –
