You can just use the jQuery s  ajax function and use its option beforeSend and define some function in which you can show something like a loader div and on success option you can hide that loader div   jQuery ajax       type   POST       url   YOU URL TO WHICH DATA SEND       data  YOUR DATA TO SEND       beforeSend  function                 loaderDiv   show               success  function data                loaderDiv   hide                You can have any Spinning Gif image  Here is a website that is a great AJAX Loader Generator according to your color scheme  http   ajaxload info

As well as setting global defaults for ajax events  you can set behaviour for specific elements  Perhaps just changing their class would be enough       myForm   ajaxSend  function           this  addClass  loading            myForm   ajaxComplete  function          this  removeClass  loading          Example CSS  to hide  myForm with a spinner    loading       display  block      background  url spinner gif  no-repeat center middle      width  124px      height  124px      margin  0 auto       Hide all the children of the  loading  element     loading         display  none

You can insert the animated image into the DOM right before the AJAX call  and do an inline function to remove it         myDiv   html   lt img src  images spinner gif  alt  Wait    gt         message   load  index php pg ajaxFlashcard   null  function           myDiv   html            This will make sure your animation starts at the same frame on subsequent requests  if that matters   Note that old versions of IE might have difficulties with the animation   Good luck

I think you are right   This method is too global      However - it is a good default for when your AJAX call has no effect on the page itself   background save for example     you can always switch it off for a certain ajax call by passing  global  false - see documentation at jquery   When the AJAX call is meant to refresh part of the page   I like my  loading  images to be specific to the refreshed section  I would like to see which part is refreshed    Imagine how cool it would be if you could simply write something like         component to refresh   ajax                And this would show a  loading  on this section   Below is a function I wrote that handles  loading  display as well but it is specific to the area you are refreshing in ajax    First  let me show you how to use it    lt  -- assume you have this HTML and you would like to refresh        it   load the content with ajax -- gt    lt span id  email  name  name  class  ajax-loading  gt   lt  span gt    lt  -- then you have the following javascript -- gt      document  ready function             email   ajax   url    my url   load true  global false          And this is the function - a basic start that you can enhance as you wish  it is very flexible    jQuery fn ajax   function options        var  this     this       debugger      function invokeFunc func  arguments                if   typeof func      function                         func  arguments                          function  think  obj  think                 if   think                         obj html   lt div class  loading  style  background  url  public images loading 1 gif  no-repeat  display inline-block  width 70px  height 30px  padding-left 25px   gt  Loading      lt  div gt                       else                       obj find   loading   hide                         function makeMeThink  think                 if    this is   ajax-loading                            think  this think                     else                        think  this  think                        options     extend     options      make options not null - ridiculous  but still         read more about ajax events     var newoptions     extend           beforeSend  function                         invokeFunc options beforeSend  null               makeMeThink true                       complete  function                         invokeFunc options complete               makeMeThink false                      success function result                        invokeFunc options success               if   options load                                  this html result                                   options          ajax newoptions

I ve used the following with jQuery UI Dialog   Maybe it works with other ajax callbacks        lt div gt  lt img src   i loading gif  id  loading    gt  lt  div gt    load   ajax html   dialog       height  300      width  600      title   Wait for it           The  contains an animated loading gif until its content is replaced when the ajax call completes

There are a couple of ways  My preferred way is to attach a function to the ajaxStart Stop events on the element itself       loadingDiv        hide       Hide it initially      ajaxStart function               this  show                ajaxStop function               this  hide               The ajaxStart Stop functions will fire whenever you do any Ajax calls   Update  As of jQuery 1 8  the documentation states that  ajaxStart Stop should only be attached to document  This would transform the above snippet to   var  loading       loadingDiv   hide      document     ajaxStart function           loading show            ajaxStop function           loading hide

As well as setting global defaults for ajax events  you can set behaviour for specific elements  Perhaps just changing their class would be enough       myForm   ajaxSend  function           this  addClass  loading            myForm   ajaxComplete  function          this  removeClass  loading          Example CSS  to hide  myForm with a spinner    loading       display  block      background  url spinner gif  no-repeat center middle      width  124px      height  124px      margin  0 auto       Hide all the children of the  loading  element     loading         display  none

I think you are right   This method is too global      However - it is a good default for when your AJAX call has no effect on the page itself   background save for example     you can always switch it off for a certain ajax call by passing  global  false - see documentation at jquery   When the AJAX call is meant to refresh part of the page   I like my  loading  images to be specific to the refreshed section  I would like to see which part is refreshed    Imagine how cool it would be if you could simply write something like         component to refresh   ajax                And this would show a  loading  on this section   Below is a function I wrote that handles  loading  display as well but it is specific to the area you are refreshing in ajax    First  let me show you how to use it    lt  -- assume you have this HTML and you would like to refresh        it   load the content with ajax -- gt    lt span id  email  name  name  class  ajax-loading  gt   lt  span gt    lt  -- then you have the following javascript -- gt      document  ready function             email   ajax   url    my url   load true  global false          And this is the function - a basic start that you can enhance as you wish  it is very flexible    jQuery fn ajax   function options        var  this     this       debugger      function invokeFunc func  arguments                if   typeof func      function                         func  arguments                          function  think  obj  think                 if   think                         obj html   lt div class  loading  style  background  url  public images loading 1 gif  no-repeat  display inline-block  width 70px  height 30px  padding-left 25px   gt  Loading      lt  div gt                       else                       obj find   loading   hide                         function makeMeThink  think                 if    this is   ajax-loading                            think  this think                     else                        think  this  think                        options     extend     options      make options not null - ridiculous  but still         read more about ajax events     var newoptions     extend           beforeSend  function                         invokeFunc options beforeSend  null               makeMeThink true                       complete  function                         invokeFunc options complete               makeMeThink false                      success function result                        invokeFunc options success               if   options load                                  this html result                                   options          ajax newoptions
