I have a function newCount that I run on Ajax success and it is working OK, however, I want to also run the same function every time the window is reloaded but for some reason I'm unable to call the function with newCount();
my code:
.ajax
$( document ).ajaxComplete(function() {
newCount();
});
.js
function newCount() {
var sum = 0;
$('.myclass').each(function() {
sum += parseFloat($(this).text());
});
// update count in html
$('#myid').html(sum);
}; // end count function
newCount(); // ajax not working when this in place
when I add newCount(); after the function, it will run correctly on page load, but the ajax will no longer work and vice versa.
What am I missing? How can I call the same function from the ajax success and every time the page is loaded?
Hey I've created this Plunker to show you how you should call the functions.
Here is the Javascript code.
<script>
(function(){
function newCount(msg) {
alert("message from: " + msg);
}; // end count function
debugger;
newCount("Page load");
$.get( "data.json", function( data ) {
alert( "Load was performed." );
});
$(document).ajaxComplete(function() {
newCount("ajax complete");
});
})();
EDIT 1
I've changed the Plunker so you can see that also works inside the $.ajax success property.
$.ajax({
url: "data.json",
data: "",
success: function() {
newCount("ajax complete");
}
});
I want to append first, then run ajax to update the data and then do the search. See the code below. I want to put a code like if append, then run $.post. How can I do that in jquery, thanks?
$('<span />', { class: 'result_tag', text: href }).insertBefore($input);
$('.result_tag').append(' ');
//make sure append first and then run .post
$.post("member_search.php", {
search_text: $(".result_tag").text()
}).done(function()
{
$.post("member_search.php", {
search_text: $(".result_tag").text()
},
function(data){
$("#find_members").html(data);
});
});
The $.post() function returns a promise. You can call the done() function on this promise. The done() function takes a callback function which will be executed after the post to the server is done:
$.post("update.inc.php", {
tag : $(this).closest("a").text(),
users_id : $("#users_id").val()
}).done(function(){
// your second post goes here
});
You can use $.ajax and its Event beforeSend like this:
$.ajax({
url: "http://fiddle.jshell.net/favicon.png",
data: 'search_text='+$(".result_tag").text(),
beforeSend: function( xhr ) {
$('.result_tag').append(' ');
}
})
.done(function( data ) {
//now do your other ajax things
});
Hope this will help you.

I have a plugin raty (http://wbotelhos.com/raty) that is loaded to document.ready, the page content changes at the click of a button reloading a part of the DOM, and the document is not ready "recalculated" and I will not reload all javascript (there are other similar behavior) I tried this solution but without success
function star(){
alert("star");
...code plugin...
}
$(document).ready(function() {
star();
});
$.ajax({
..code..
done: function(creaStella) {
alert("D");
star();
},
complete:function(){
alert("C");
star();
},
});
After call ajax i have alert("star") but i haven't my div populated
Incorrect usage of $.ajax
$.ajax({
..code..
success: function(creaStella) {
//code to populate div goes here
alert("complete");
star();
}
}).done(function(){
//or here
alert("complete2");
});
use success/done as show (or both).
I resolve in this Way..(promise().done)
also form with jquery validate plugin before dosen't works
function star(){
//plugin star
}
$(document).ready(function() {
formJqueryValidate1();
formJqueryValidate2();
star();
});
function formJqueryValidate1() {
//my check
function formJqueryValidate2() {
//my check
}
$.ajax({
success: function(msg) {
$('#myid').html(msg.template).promise().done(function(){
formJqueryValidate1();
formJqueryValidate2();
star();
});
}
}
});
I have an ajax function that creates a link that triggers another ajax function. For some reason the second ajax function refuses to go through POST event if I've set type: "POST"
The two functionas are below:
function HandleActivateLink(source) {
var url = source.attr('href');
window.alert(url)
$.ajax({
type: "POST",
url: url,
success: function (server_response) {
window.alert("well done")
}
});
return false;
}
function HandleDeleteLink() {
$('a.delete-link').click(function () {
var url = $(this).attr('href');
var the_link = $(this)
$.ajax({
type: "POST", // GET or POST
url: url, // the file to call
success: function (server_response) {
if (server_response.object_deleted) {
FlashMessage('#form-success', 'Link Deleted <a class="activate-link" href="' + url.replace('delete', 'activate') + '">Undo</a>');
$('a.activate-link').click(function(){
HandleActivateLink($(this));
});
the_link.parent().hide();
} else {
var form_errors = server_response.errors;
alert(form_errors)
}
}
});
return false;
});
}
You'll notice HandleDeleteLink creates a new link on success, and generates a new click event for the created link. It all works butHandleActivateLink sends the request to the server as GET. I've tried using $.post instead with no luck.
Any pointers, much appreciated.
In the second event you do not inform the client to prevent the default behaviour.
One way to do this would be to change:
$('a.activate-link').click(function(){
HandleActivateLink($(this));
});
to:
$('a.activate-link').click(function(){
return HandleActivateLink($(this));
});
(This works because HandleActiveLink already returns false.)
A nicer way to do this is to pass in the event argument to the click function and tell it to preventDefault
$('a.activate-link').click(function(e){
e.preventDefault();
HandleActivateLink($(this));
});
what is your url?
btw You can't send a cross-domain post via javascript.
I want a basic spinner or processing animation while my AJAX POST is processing. I'm using JQuery and Python. I looked at the documentation but can't figure out exactly where to put the ajaxStart and ajaxStop functions.
Here is my js:
<script type="text/javascript">
$(function() {
$('.error').hide();
$("#checkin-button").click(function() {
var mid = $("input#mid").val();
var message = $("textarea#message").val();
var facebook = $('input#facebook').is(':checked');
var name = $("input#name").val();
var bgg_id = $("input#bgg-id").val();
var thumbnail = $("input#thumbnail").val();
var dataString = 'mid='+mid+'&message='+message+'&facebook='+facebook+'&name='+name+'&bgg_id='+bgg_id+'&thumbnail='+thumbnail;
$.ajax({
type: "POST",
url: "/game-checkin",
data: dataString,
success: function(badges) {
$('#checkin-form').html("<div id='message'></div><div id='badges'></div>");
$('#message').html("<h2><img class=\"check-mark\" src=\"/static/images/check-mark.png\"/>You are checked in!</h2>");
$.each(badges, function(i,badge) {
$('#badges').append("<h2>New Badge!</h2><p><img class='badge' src='"+badge.image_url+"'><span class='badge-title'>"+badge.name+"</span></p>");
});
}
});
return false;
});
});
</script>
$.ajax({
type: "POST",
url: "/game-checkin",
data: dataString,
beforeSend: function () {
// ... your initialization code here (so show loader) ...
},
complete: function () {
// ... your finalization code here (hide loader) ...
},
success: function (badges) {
$('#checkin-form').html("<div id='message'></div><div id='badges'></div>");
$('#message').html("<h2><img class=\"check-mark\" src=\"/static/images/check-mark.png\"/>You are checked in!</h2>");
$.each(badges, function (i, badge) {
$('#badges').append("<h2>New Badge!</h2><p><img class='badge' src='" + badge.image_url + "'><span class='badge-title'>" + badge.name + "</span></p>");
})
}
});
http://api.jquery.com/jQuery.ajax/:
Here are the callback hooks provided by $.ajax():
beforeSend callback is invoked; it receives the jqXHR object and the settings map as parameters.
error callbacks are invoked, in the order they are registered, if the request fails. They receive the jqXHR, a string indicating the error type, and an exception object if applicable. Some built-in errors will provide a string as the exception object: "abort", "timeout", "No Transport".
dataFilter callback is invoked immediately upon successful receipt of response data. It receives the returned data and the value of dataType, and must return the (possibly altered) data to pass on to success.
success callbacks are then invoked, in the order they are registered, if the request succeeds. They receive the returned data, a string containing the success code, and the jqXHR object.
complete callbacks fire, in the order they are registered, when the request finishes, whether in failure or success. They receive the jqXHR object, as well as a string containing the success or error code.
Note the beforeSend and complete method additions to the code.
Hope that helps.
If you're using jQuery 1.5 you could do that nicely, unobtrusively and generically with a prefilter. Let's make a very simple plugin for this:
(function($) {
var animations = {};
$.ajaxPrefilter(function( options, _, jqXHR ) {
var animation = options.animation && animations[ options.animation ];
if ( animation ) {
animation.start();
jqXHR.then( animation.stop, animation.stop );
}
});
$.ajaxAnimation = function( name, object ) {
if ( object ) {
animations[ name ] = object;
}
return animations[ name ];
};
})( jQuery );
You install an animation as follows:
jQuery.ajaxAnimation( "spinner" , {
start: function() {
// code that starts the animation
}
stop: function() {
// code that stops the animation
}
} );
then, you specify the animation in your ajax options:
jQuery.ajax({
type: "POST",
url: "/game-checkin",
data: dataString,
animation: "spinner",
success: function() {
// your success code here
}
});
and the prefilter will ensure the "spinner" animation is started and stopped when needed.
Of course, that way, you can have alternative animations installed and select the one you need per request. You can even set a default animation for all requests using ajaxSetup:
jQuery.ajaxSetup({
animation: "spinner"
});
The best method I have found, assuming you are populating a present but empty field is to have a .loading class defined with background-image: url('images/loading.gif') in your CSS. You can then add and remove the loading class as necessary with jQuery.
you can set global ajax loading icon handler using here #ajxLoader takes your loading icon
$( document ).ajaxStart(function() {
$("#ajxLoader").fadeIn();
});
$( document ).ajaxComplete(function() {
$("#ajxLoader").fadeOut();
});
$(function() {
$('.error').hide();
$("#checkin-button").click(function() {
var mid = $("input#mid").val();
var message = $("textarea#message").val();
var facebook = $('input#facebook').is(':checked');
var name = $("input#name").val();
var bgg_id = $("input#bgg-id").val();
var thumbnail = $("input#thumbnail").val();
var dataString = 'mid=' + mid + '&message=' + message + '&facebook=' + facebook + '&name=' + name + '&bgg_id=' + bgg_id + '&thumbnail=' + thumbnail;
$.ajax({
type : "POST",
url : "/game-checkin",
data : dataString,
beforeSend : function() {
$('#preloader').addClass('active');
},
success : function(badges) {
$('#preloader').removeClass('active');
$('#checkin-form').html("<div id='message'></div><div id='badges'></div>");
$('#message').html("<h2><img class=\"check-mark\" src=\"/static/images/check-mark.png\"/>You are checked in!</h2>");
$.each(badges, function(i, badge) {
$('#badges').append("<h2>New Badge!</h2><p><img class='badge' src='" + badge.image_url + "'><span class='badge-title'>" + badge.name + "</span></p>");
});
},
complete : function() {
$('#preloader').removeClass('active');
}
});
return false;
});
});
#preloader{
background: url(staticpreloader.gif);
}
.active {
background: url(activepreloader.gif);
}
I wrote a blog post about how to do this on a generic document level.
// prepare the form when the DOM is ready
$(document).ready(function() {
// Setup the ajax indicator
$('body').append('<div id="ajaxBusy"><p><img src="images/loading.gif"></p></div>');
$('#ajaxBusy').css({
display:"none",
margin:"0px",
paddingLeft:"0px",
paddingRight:"0px",
paddingTop:"0px",
paddingBottom:"0px",
position:"absolute",
right:"3px",
top:"3px",
width:"auto"
});
});
// Ajax activity indicator bound to ajax start/stop document events
$(document).ajaxStart(function(){
$('#ajaxBusy').show();
}).ajaxStop(function(){
$('#ajaxBusy').hide();
});
The AJAX process starts when you run the $.ajax() method, and it stops when the 'complete' callback is run. So, start your processing imagery/notification right before the $.ajax() line, and end it in the 'complete' callback.
ajaxStart and ajaxStop handlers can be added to any elements, and will be called whenever ajax requests start or stop (if there are concurrent instances, start only gets called on the first one, stop on the last to go). So, it's just a different way of doing global notification if you had, for example, a status spinner somewhere on the page that represents any and all activity.
