为什么ajax请求被中止……？

Question

I am sending ajax request to server

$.ajax({
    type: "POST",
    data: checkin_push,
    url: api_url + 'file.php?token=' + last_token + '&date=' + dated,
    dataType: "json",
    timeout: 100000, // 100 seconds
    success: function(data) {
        // invoke sync
        api_pending_sync = true;            
        // checkin back to home
        $.mobile.changePage('#home', { reverse: true });
        //api_sync_message
        $('#sync-message').fadeIn(300).html('<div class="ui-body ui-body-e ui-corner-all" style="margin-bottom: 20px;" data-theme="d">Successfully checked in for ' + checkin_display_date() + '.</div>').fadeOut(5000);
    },
    complete: function(jqXHR, textStatus) {
        $.mobile.hidePageLoadingMsg();
    },
    error: function() {
        $('#checkin-status-message').fadeIn(300).html('<div class="ui-body ui-body-e ui-corner-all" style="margin-bottom: 20px; color: red;" data-theme="d">Unable to Check In, Please check your internet connection and try again.</div>').fadeOut(5000);
    }
});

Here is relevant code of file.php

     =========rest code -=================

    #------------------- send alert to life lines (send alerts) -------------------

$query = query("SELECT email, phone, sms_carrier FROM table WHERE account_id = ".escape($account_id));
if ((mysqli_num_rows($query) > 0) and $send_alert) 
{
   while ($l = mysqli_fetch_assoc($lifelines)) 
   {

           // send mail 
           /* this function is returning value of mail() function*/
       send_alert_email($userEmail, $sms_email, 'alert-2');

   }
}
#-------------------------------(/alerts)--------------------------------------

$return = array('answers' => $answers); //, 'transact' => $checkin_transact);
 }

 json_out($return);

 ?>

Now what exactly happening is .. if control is coming in while loop and email is getting send the firebug shows status as 'aborted' otherwise it is working fine ... what am I doing wrong..

Thanks in advance

Answer 1

Can you replace the following line:

error: function() {

with the following:

error: function(jqXHR, textStatus, errorThrown){

and check the value of textStatus and errorThrown to see what was the error when the request aborted.

Hope this helps.

 $.ajax({
    type: "POST",
    data: checkin_push,
    url: api_url + 'file.php?token=' + last_token + '&date=' + dated,
    ...

You are sending both GET & POST parameters. So, just want to make sure, you are not getting null for any parameter.

In file.php,

make sure to get the token and date values as $_GET

& checkin_push sent parameter-values as $_POST

or

get all the sent parameters values as $_REQUEST
