jQuery should I use multiple ajaxStart/ajaxStop handling

Maybe there is no difference, but is either way better than the other (or perhaps a mysterious 'third' way better than both!)...

first:

var startTime;

$(document).ready(function() {

$("#lbl_ajaxInProgress").ajaxStart(function() {
    // store the current date/time...
    startTime = new Date();
    // update labels
    $(this).text('Yes');
    $("#lbl_ajaxCallTime").text("-");
});

$("#lbl_ajaxInProgress").ajaxStop(function() {
    // update labels
    $(this).text('No');
    $("#lbl_ajaxCallTime").text(myFunctionThatCalculatesTime(startTime));
});

});

second:

var startTime;

$(document).ready(function() {

$("#lbl_ajaxInProgress").ajaxStart(function() {
    // update labels
    $(this).text('Yes');
});

$("#lbl_ajaxInProgress").ajaxStop(function() {
    // update labels
    $(this).text('No');
});

$("#lbl_ajaxCallTime").ajaxStart(function() {
    // store the current date/time...
    startTime = new Date();
    // update labels
    $(this).text("-");
});

$("#lbl_ajaxCallTime").ajaxStop(function() {
    // update labels
    $(this).text(myFunctionThatCalculatesTime(startTime));
});

});

From stackoverflow davidsleeps

• An interesting fact is that ajaxStart, etc. are actually just jQuery events. For instance:

  $("#lbl_ajaxInProgress").ajaxStart(function() {
    // update labels
    $(this).text('Yes');
  });
  

  is equivalent to:

  $("#lbl_ajaxInProgress").bind("ajaxStart", function() {
    // update labels
    $(this).text('Yes');
  });
  

  This means that you can also attach namespaces to ajaxStart/ajaxStop, etc. Which also means that you can do:

  $("#lbl_ajaxInProgress").unbind("ajaxStart ajaxStop");
  

  You could also do:

  $("#lbl_ajaxInProgress").bind("ajaxStart.label", function() {
    // update labels
    $(this).text('Yes');
  });
  
  $("#lbl_ajaxInProgress").bind("ajaxStop.label", function() {
    // update labels
    $(this).text('No');
  });
  

  And then:

  $("#lbl_ajaxInProgress").unbind(".label");
  

  Cool, huh?

  davidsleeps : certainly is! i'm assuming here, but you're saying that it doesn't matter which way?

  Yehuda Katz : the ajaxStart helper is equivalent to the click helper, which just delegates to bind, so yes, it doesn't matter either way.
