So, for some reason my script refuses to work, although it seems to be correct.
I tried using $.ajax instead, but not working with that either. Any ideas what's gone wrong?
<script>
$(document).ready(function() {
$('#saveForm .submit').click(function() {
var _user = $('#saveForm .user');
_userId = $('#saveForm .userId');
_password = $('#saveForm .password');
$('#saveForm').append('<p>Loading...</p>');
$.post("ajax/fetchPhotos.php", {user:_user, userId:_userId, password:_password}, function(data) {
alert(data);
});
return false;
});
});
</script>
In ajax/fetchPhotos.php i have this:
<?php
set_time_limit(0);
session_start();
require_once("includes/functions.php");
require_once("includes/pclzip.lib.php");
/*
Huge block of code here (commented out for the moment)
*/
echo "wut?";
So, when clicking .submit, it should send a request to fetchPhotos.php with three params and then alert "wut?". Right now the page hangs in chrome.. nothing happens. In firefox the page just refreshes. I do get one error in the console, but i only see it for a split second as the page refreshes directly.
Thanks,

you must use the .val() method to get the value of the inputs.
try this way:
<script>
$(document).ready(function() {
$('#saveForm .submit').bind('click', function() {
var
user = $('#saveForm .user').val(),
id = $('#saveForm .userId').val(),
password = $('#saveForm .password').val();
$('#saveForm').append('<p>Loading...</p>');
$.post("ajax/fetchPhotos.php", {user:user, userId:id, password:password}, function(data) {
alert(data);
});
return false;
});
});
</script>
It seems syntax related problem and also try with absolute url or can do in this way
new Ajax.Request("ajax/fetchPhotos.php", {
method: 'post',
parameters: 'id='+id,
onComplete: function(transport) {
alert(transport.responseText);
}
});

i am using smoke.js which allows to style the classic alert javascript windows.
All you have to do is place .smoke before the alert ie. smoke.confirm()
The issue I am having is with the ok/cancel callback, it isnt working for me.
This is the example the website shows.
`You can implement these the same way you'd use the js alert()...just put "smoke." in front of it.
The confirm() replacement, however, needs to be used just a little differently:
smoke.confirm('You are about to destroy everything. Are you sure?',function(e){
if (e){
smoke.alert('OK pressed');
}else{
smoke.alert('CANCEL pressed');
}
});
and the code I have is;
$(".upb_del_bookmark").click( function() {
if(smoke.confirm(delete_message)) {
var post_id = $(this).attr('rel');
var data = {
action: 'del_bookmark',
del_post_id: post_id
};
$.post(upb_vars.ajaxurl, data, function(response) {
$('.bookmark-'+post_id).fadeOut();
$('.upb_bookmark_control_'+post_id).toggle();
});
It shows the style button and everything but when i click on OK it doesnt perform the function above, nothing happens.
So i rewrote it to
$(".upb_del_bookmark").click( function() {
if(smoke.confirm(delete_message, function(e))) {
if(e){
var post_id = $(this).attr('rel');
var data = {
action: 'del_bookmark',
del_post_id: post_id
};
$.post(upb_vars.ajaxurl, data, function(response) {
$('.bookmark-'+post_id).fadeOut();
$('.upb_bookmark_control_'+post_id).toggle();
});
}}
But now when i click it doesnt even show anything
I am not a programmer, Help!!!!!
If you want to try it go to latinunit.org login with david:123321 and then go to a post and try to add it to your favourites
Update
I tried the following, it shows the window but it doesnt perform the function;
$(".upb_del_bookmark").click( function() {
smoke.confirm(delete_message, function(e) {
if(e){
var post_id = $(this).attr('rel');
var data = {
action: 'del_bookmark',
del_post_id: post_id
};
$.post(upb_vars.ajaxurl, data, function(response) {
$('.bookmark-'+post_id).fadeOut();
$('.upb_bookmark_control_'+post_id).toggle();
});
}})
return false;
});
Here is the js file of the smoke script Link
When i click on cancel the following shows;
Uncaught TypeError: Property 'callback' of object # is not a
function Line:198
Uncaught TypeError: Property 'callback' of object # is not a
function Line:208
The following is what's on those linesof the smoke script;
finishbuildConfirm: function (e, f, box)
{
smoke.listen(
document.getElementById('confirm-cancel-' + f.newid),
"click",
function ()
{
smoke.destroy(f.type, f.newid);
f.callback(false);
}
);
smoke.listen(
document.getElementById('confirm-ok-' + f.newid),
"click",
function ()
{
smoke.destroy(f.type, f.newid);
f.callback(true);
}
);
The builtin javascript alert/confirm functions are synchronous, this is not. You need to handle the result of the confirm using the javascript callback pattern. You pass a function to the smoke.confirm() function which called when you need to respond to an action.
See the following code. The if around the smoke.confirm() has been removed and the handling code is wrapped in the function passed to the smoke.confirm() function.
$(".upb_del_bookmark").click( function() {
smoke.confirm(delete_message, function(e) {
if(e){
var post_id = $(this).attr('rel');
var data = {
action: 'del_bookmark',
del_post_id: post_id
};
$.post(upb_vars.ajaxurl, data, function(response) {
$('.bookmark-'+post_id).fadeOut();
$('.upb_bookmark_control_'+post_id).toggle();
});
}
});
}
I highly recommend reading a little about the callback pattern in javascript. It's very common and understanding it will help you use this plugin and many others.
<form>
<input type="text" id="user"/>
<input type="button" value="Submit" onClick="post();" />
</form>
<div id="result"> </div>
<script type="text/javascript">
function post()
{
var username = $('#user').val();
$.post('battlephp.php',
{postuser:user}
)
}
</script>
Its a simple Ajax code.. It should take username and display the Php code!
But don't know why its not running?? Actually I am learning...so I cant rectify the error or fault??
I am running ii on localhost.. so is there any problem with using:
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"></script>
display the Php code
No, it shouldn't.
First, you've changed your mind about the variable name you are using (user, username) half way through your script, so you are going to throw a reference error.
Second, you haven't provided a function (the third argument) to $.post, so you aren't doing anything (such as displaying it) with the returned data.
Third, the server should execute the PHP and return its output. You shouldn't get the actual PHP code.
function post() {
var username = $('#user').val();
$.post(
'battlephp.php',
{postuser:username}, // Be consistent about your variable names
function (data) {
alert(data);
}
);
}
Instead
document.ready()
you can use
jQuery(function($){...});
Try to do this:
<script>
$(document).ready(function() {
function post() {
var username = $('#user').val();
$.ajax({
type : 'post',
url : 'batttlephp.php',
data : {
postuser : user
},
success : function(data) {
alert(data);
},
error : function(data) {
alert(data);
}
});
});
});
</script>
if you're doing a ajax request then is good also handle success and error...
Also I suggest to you "to start the document".
Try the code above and let us know if worked
I have an application that I'm writing that, in one aspect of it, you click on a checkmark to complete a task, a popup window is displayed (using bootstrap), you enter your hours, and then that is sent to a PHP page to update the database. I'm using FF (firebug) to view the post. It's coming up red but not giving me an error. The only thing I'm doing is echoing out "sup" on the PHP page, and it's still showing errors, and I can't figure out why.
This is my initial click function:
$('.complete').on('click', function(event) {
var id = $(this).attr('data-id');
var tr = $(this).parent().parent();
var span = $(tr).children('td.task-name');
var r = (confirm('Are you sure you want to complete this task?'));
if (r){
addHours(id);
} else {
return false;
} // end else
});
That works fine, and it fires my next function which actually fires the bootstrap modal:
function addHours(id) {
var url = 'load/hours.php?id='+id;
$.get(url, function(data) {
$('<div class="modal hide fade in" id="completeTask">' + data + '</div>').modal()
.on('shown', function() {
pendingTask(id);
}); // end callback
}).success(function() {
$('input:text:visible:first').focus();
});
} // end function
This is also working, and the modal is displayed just fine. However, whenever I post the form to my logic page, it fails for no reason. This is the function to post the form to the logic page:
function pendingTask(id) {
$('.addHours').on('click', function(event) {
var formData = $('form#CompleteTask').serializeObject();
$.ajax({
url:'logic/complete-with-hours.php',
type: 'POST',
dataType: 'json',
data: formData,
success: function(data) {
if (data.status == 'error') {
$(this).attr('checked', false);
//location.reload();
} // end if
else {
$(this).attr('checked', true);
//location.reload();
} // end else
},
dataType: 'json'
});
}); // end click
} // end function
When this is fired, I see this in my Firebug console:
I know this is a lot of information, but I wanted to provide as much information as I could. Every other post function in the application is working fine. It's just this one. Any help would be appreciated.
Thanks in advance.
The jQuery.ajax data parameter takes a simple object of key value pairs. The problem could be that the object created by serializeObject() is too complex. If that's the case, you could either process the formData object to simplify it or try data: JSON.stringify(formData)
Does serializeObject() even exist in jQuery? is that a function you wrote yourself? Can you use jQuery functions like serialize() or serializeArray() to serialize the form data and see how it goes.
Usually the red indicates a 404 response error. We can't tell in this screen shot. Check your php code by directly calling the requested page and getting a proper response.
Also make sure your dataType is application/json which is the proper mime type header (though I don't think this is causing the error). You also should only have dataType once (you have it again at the bottom)
I figured it out. I changed the post type from the structure I entered above to a standard post:
$("#CompleteTask").validate({
submitHandler: function(form) {
var hours = $('#hours').val();
$.post('logic/complete-with-hours.php', {'hours': hours, 'id':id},
function(data){
if (data.status == 'success') {
$(checkmark).attr('checked', false);
$('.message').html(data.message).addClass('success').show();
} // end if
if (data.status == 'error') {
$('.message').html(data.message).addClass('error').show();
} // end else
},
"json"
); //end POST
} // end submit handler
}); // end validate
That seemed to do the trick
I am experiencing the strangest behaviour on our website, and it is making things incredibly slow.
My team and I have a website running entirely on AJAX. So for the login, I have some js ajax that loads the login box into our index page. The html containing the login box has a script link in the head. This script listens for the login form submission, and sends the form data to the server for authentication through ajax.
The html that contains the login box only gets loaded once, but the js file that it links to gets loaded multiple times. The amount of times change. From 5 times to 15 times and I cannot see a pattern or anything. This happens everywhere on our site, not just at login time.
This issue really has me stumped and I'm totally stuck. Is it because I have ajax in a js file that is loaded in initially with ajax?
I would really appreciate your insight and help!
EDIT:
As requested, some code:
This is a stripped down version of loadContent() in the Interface.js file. This specific function loads all site content into the content area on index.php. When the page is refreshed, the first thing sent to the function is the location of the login.php file, containing the login box:
loadContent: function(page) {
var self = this;
//just some animations to make things look good
$(self.error).fadeOut(150, function() {
$(self.content).fadeOut(150, function() {
$(self.loading).fadeIn(150, function() {
$.ajax({
url: page,
success: function(data) {
//response data
var $response = $(data);
$(self.content_1).html($response);
//definitions for contentbox-2
self.contentHeading_2.html("Replies:");
self.content_2.html(postReplies);
//redisplay the content after it has loaded in.
$(self.loading).fadeOut(150, function() {
$(self.content).fadeIn(150, function() {
// Content faded in
});
});
},
error: function() {
$(self.loading).fadeOut(150, function() {
$(self.error).fadeIn(150, function() {
// Error faded in
});
});
}
});
});
});
});
this.page = page;
}
And then the login.php file:
<!DOCTYPE HTML>
<html>
<head>
<title></title>
<script type="text/javascript" src="js/login.js"></script>
</head>
<body>
<div class="padded loginphp">
<div id="loginbox">
<!-- the login box comes here
</div> <!-- #loginbox -->
</div>
</body>
</html>
And the login.js file:
$(document).ready(function() {
$('#honeyloginform').submit(function(event) {
//event.preventDefault();
login();
return false;
});
});
function login() {
$('.errorinputfields').removeClass('errorinputfields');
if (isEmpty($('#username'))) {
$('#username').addClass('errorinputfields');
$('#username').focus();
return;
}
if (isEmpty($('#password'))) {
$('#password').addClass('errorinputfields');
$('#password').focus();
return;
}
$('#honeyloginform').fadeOut(100, function(){
$('#loginbox .loading').fadeIn(300, function(){
var pword = $('#password').val();
var remember = "no";
if ($('#remember').is(':checked')) {
remember = "yes";
}
var JSONobj = {
username: $('#username').val(),
password: pword,
rem: remember
};
$.ajax({
url: 'ajax/login.php',
data: JSONobj,
success: function(data) {
//alert(data);
var JSONobj = JSON.parse(data);
if (JSONobj.Success) {
Interface.login(); //just loads the landing page after login
//window.setTimeout('location.reload()', 300);
} else {
$('#loginbox .loading').fadeOut(300,function(){
$('#honeyloginform').fadeIn(300);
});
$('#username').focus();
$('#loading-message').text(JSONobj.Message).show();
}
}
});
});
});
}
I've managed to find the problem, and fix it!
I've made a change to my interface layout, and as a result, the three selectors, $(self.error), $(self.content) and $(self.loading) each contain more than one element, where it always only contained one each.
This seems to cause the callback functions to be compounded or something, as everything inside the final callback in loadContent() was called 9 times.
So it was a simple case of redefining the selectors, so that they refer to one element each.
Why doesn't the following pick up the form? All it does is just to do a normal PHP post without throwing any errors...
I'm using blockUi on this as well, hence block/unblock.
$(document).ready(function(){
$("input.update").click(function(){
var str = $(this).parent().serialize();
$(this).parent().parent().block({ message: "<span class=\"loading\"><img src=\"<?php echo $siteUrl ?>/admin/template/images/loading.gif\" alt=\"loading...\" /><p>Updating...</p></span>" });
$.ajax({
type: "POST",
url: "forms/update.php",
data: str,
success: function(){
$("div.edit_box").unblock();
$("div.edit_box").append("<span class=\"success\">This has been updated!</span>");
}
});
return false;
});
});
This is my first attempt at using jQuery's Ajax functionality so please bear with me.
("input.update").click(function(){
should be
$("input.update").click(function(){
Since it seems you're only using the 'success' callback of post you could use the .post method, which is a bit easier on the eyes. Also you can put those block calls inside ajaxStart and ajaxStop. To me it's neater.
The $(this).parent().parent().block seemed wrong to me, I changed it to reference the same element that is used for unblocking. I'd also be checking the output of the PHP script, to make sure that whatever you are 'updating' actually is updated (just echo XML from PHP and you'll see it on your console log).
$(function() {
// Apply click handlers to anchors
$("input.update").click(function(e){
// Stop normal link click
e.preventDefault();
var str = $(this).parent().serialize();
// Send request
var action = "forms/update.php";
$.post(action, {data:str}, function(xml) {
console.log(xml);
$("div.edit_box").append("<span class=\"success\">This has been updated!</span>");
})
});
// Adds a wait indicator to any Ajax requests
$(document.body).ajaxStart(function() {
$("div.edit_box").block({ message: "<span class=\"loading\"><img src=\"<?php echo $siteUrl ?>/admin/template/images/loading.gif\" alt=\"loading...\" /><p>Updating...</p></span>" });
}).ajaxStop(function() {
$("div.edit_box").unblock();
$("div.edit_box").append("<span class=\"success\">This has been updated!</span>");
});
});
