Question

Cette forme de code fonctionne, mais il n'appelle pas le formulaire ajax chat_process.php. J'ai besoin d'appeler le formulaire ajax et d'alerter un message.

var html = ""; 

for(...) { 
    html += '<form class="form_deletechatmessage" action="chat_process.php" method="post">'; 
    html += '<button type="submit" class="trashchat">Delete</button>' 
    html += '<input type="hidden" name="task" value="chatdelete">'; 
    html += '<input type="hidden" name="token" value="80a86781f1ab0200c17e4a39f42588e5">'; 
    html += '<input type="hidden" name="id" value="1">'; 
    html += '</form>'; 
} 

$('#discussion').append(html); 

$(".form_deletechatmessage").ajaxForm({ 
    success  : function(result) {   
     var result = trim(result); 

     if(result == 'success') { 
      alert("Success"); 
     } else { 
      alert(result); 
     } 
    }  
}); 

Le code complet:

function getChatText(){ 
    $.ajax({ 
     dataType: 'json', 
     url: "chat_process.php?task=refresh&token=" + token + "&lastTimeID=" + lastTimeID, 
     success: function(data) { 
       var jsonData = JSON.parse(data); 
       var jsonLength = jsonData.results.length; 
       var html = ""; 
       for (var i = 0; i < jsonLength; i++) { 
        var result = jsonData.results[i]; 

        var ida = $("#ida").val(); 

        var you = ""; 

        html += '<form class="form_deletechatmessage" action="chat_process.php" method="post">'; 
        if(ida == result.aid) { 
         html += '<li class="self">'; 
         you = " (ti)" 
        } else { 
         html += '<li class="other">'; 
        } 
        html += '<div class="avatar"><img src="http://localhost/project/images/avatars/' + result.aid + '/' + result.avatar + '" /></div>'; 
        html += '<div class="messages">'; 
        html += '<button type="submit" class="trashchat" title="Izbriši poruku"><i class="fa fa-trash-o"></i></button>'     
        html += '<p><font style="font-weight: 600; color: ' + result.color + '">' + result.name + you + '</font> kaže:</p>'; 
        html += '<p>' + result.chattext + '</p>'; 
        html += '</div>'; 
        html += '</li>'; 
        html += '<input type="hidden" name="task" value="chatdelete">'; 
        html += '<input type="hidden" name="token" value="' + token + '">'; 
        html += '<input type="hidden" name="id" value="' + result.id + '">'; 
        html += '</form>'; 

        lastAdminID = result.aid; 
        lastTimeID = result.id; 
       } 
       if(html != "" && lastTimeID != 0) { 
        $('.discussion').append(html); 

        var objDiv = $(".discussion"); 
        objDiv.scrollTop = objDiv.scrollHeight; 

        if(ida != result.aid) { 
         audioElement.play(); 

         $.titleAlert("Imate novu poruku!", { 
          requireBlur:  false, 
          stopOnFocus:  true, 
          stopOnMouseMove: true, 
          interval:   700 
         }); 
        }         
       } 
     }, 
    }); 
}

probablement votre appel ajax échoue et il semble que vous attendez erreur dans votre bloc de succès par:

if(result == 'success') { 
    alert("Success"); 
} else { 
    alert(result); 
} 

Vous devez vous attendre erreur bloc d'erreur non dans le bloc de succès:

$(".form_deletechatmessage").ajaxForm({ 
      success  : function(result) {   
       alert(result) 
      }, 
      error: function(XMLHttpRequest, textStatus, errorThrown) { 
       alert(textStatus + errorThrown); 
     }  
    });
