javascript - How to change this ajax code to long polling -


this question exact duplicate of:

this ajax code please can tell me how can change code long polling ?

here code :-

var chat = {} chat.fetchmessages = function () {   $.ajax({     url: 'ajax/ajax/chat.php',     type: 'post',     data: { method: 'fetch' },     success: function(data) {       $('#chats').html(data);     }   });  } chat.interval = setinterval(chat.fetchmessages, 1000);

you have put next call of fetchmessage in callback of previous 1 :

var chat = {} chat.fetchmessages = function () {   $.ajax({     url: 'ajax/ajax/chat.php',     type: 'post',     data: { method: 'fetch' },     success: function(data) {       $('#chats').html(data);       chat.fetchmessages(); // let's again     }   });  } chat.fetchmessages(); // first call
