I've a WordPress blog running this jQuery code that allows users to click a bookmark link that saves the post as a bookmark. Each post shows a total bookmark counter that looks like: "Bookmarked (5)". Although this code works, it registers multiple clicks whenever someone clicks multiple times on the bookmark link and then saves the same post as multiple bookmarks. When the user tries to remove the bookmark by clicking on the bookmark link again, it registers multiple clicks again and the counter starts showing minus numbers which looks like: "Bookmarked (-5)".
I've been searching for an instruction on how to prevent this from happening so that the bookmark counter never runs minus and the user can't bookmark the same post multiple times but had no success so far.
Here is the jQuery code that I'm using:
jQuery(document).ready( function($) {
var added_message = upb_vars.added_message;
var delete_message = upb_vars.delete_message
$(document).on('click', '.upb_add_bookmark', function () {
var post_id = $(this).attr('rel');
var data = {
action: 'bookmark_post',
post_read: post_id
};
$.post(upb_vars.ajaxurl, data, function(response) {
$('.upb_bookmark_control_'+post_id).toggle();
if($('.upb-bookmarks-list').length > 0 ) {
var bookmark_data = {
action: 'insert_bookmark',
post_id: post_id
};
$.post(upb_vars.ajaxurl, bookmark_data, function(bookmark) {
$(bookmark).appendTo('.upb-bookmarks-list');
$('.no-bookmarks').fadeOut();
});
}
});
return false;
});
$(document).on('click', '.upb_del_bookmark', function () {
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;
});
});
Could you please help me solve this problem?
Thanks a lot!
One way is to add a .disabled class to your link before the $.post().
// Before ajax...
if ($(this).hasClass('disabled')) {
return false;
} else {
$(this).addClass('disabled');
}
// Make sure we refer to the same element
var that = this;
// On post success...
$(that).removeClass('disabled');

I am trying to extract all the comments of an article found on the yahoo news page using casperjs.
What I do first is to click on the "ver reacciones" button, then click on the response button of the first comments loaded to show the response comments.
So far, get the first comment and your answer, but I can not find the way to get all the answers of all the comments, in a few words, all the comments and the response comments found on the page.
Any algorithm that will help me get it?.

So here is the problem:
I have two click event in one page. The first when you click on a thumbnail picture it's open a modal which shows a bigger image like Instagram on PC (I make an Instagram clone for practicing btw). The other button is for show more image.
The problem is, I use ajax for both click to get some variable and pass to the php. When the page loaded it's shows only 3 image and when I clicked one of them It's shows the right image in the modal but when I click show more it shows 3 more and after when I clicked on the thumbnail it's stucked. I mean its shows only one picture doesn't matter which thumbnail i clicked so the ajax request not runs again. I hope you can understand the problem and can help me. (sorry for my English).
So here is the code:
This is the ajax calling function:
function ajaxShow(urls,datas,element){
$.ajax({
url: urls,
data: {datas: datas},
cache:true,
}).always(function(result){
console.log("done");
element.html(result);
});
}
And these are the click events:
$(document).ready(function(){
//Open picture in modal
var pic = $(".pics");
var modalCont = $(".modal-content");
pic.on('click',function(event){
event.preventDefault();
var id = $(this).attr('data-id');
console.log(id);
ajaxShow("../php/ajax_modal.php",id,modalCont);
});
//Load more
var smbt = $(".smbt");
var limit = $(smbt).data('loaded');
smbt.on('click',function(event) {
event.preventDefault();
var cont = $("#cont");
limit += 3;
console.log(limit);
ajaxShow("../php/show_more.php",limit,cont);
});
});
In a nutshell: After I clicked on load more the modal open ajax request not run again.
Use overloaded version of .on() on document node.
$(document).on(events, selector, data, handler );
So your code should be rewritten as this:
$(document).on('click', '.pics', null, function (event) {
event.preventDefault();
var id = $(this).attr('data-id');
console.log(id);
ajaxShow("../php/ajax_modal.php",id,modalCont);
});
and
$(document).on('click', '.smbt', null, function (event) {
event.preventDefault();
var cont = $("#cont");
limit += 3;
console.log(limit);
ajaxShow("../php/show_more.php",limit,cont);
});
I am using two scripts on my page and there is a general click function which records the number of clicks one user is making. So when I click on any element in the document, the click function should run after which other functions on the same element runs. But in my case, the click function runs multiple times before passing the control to the other function.
/************ 1st Jquery Script ***************/
function($) {
$(function(e) {
$('.signupCustom').click(function(){
var email = $('#form-email').val()
var password = $('#pass').val()
var firstName= $('#form-first-name').val()
var lastName= $('#form-last-name').val()
var number= $('#form-mobile').val()
var type=$('#sel1').val()
$.ajax({
url: '/login',
type: 'GET',
data: {
'email': email,
'password':password,
'firstName':firstName,
'lastName':lastName,
'number':number,
'type':type
},
success: function(data){
if ($('#sel1').val() == "Travel-Agent"){
window.location.href = "/agentVerification.html"
}
else{
window.location.href = "/dashboardTraveller"
}
}
})
})
$('.login').click(function(){
var email = $('#form-username').val()
var password= $('#form-password').val()
$.ajax({
url: '/loginCustom',
type: 'GET',
data: {
'email': email,
'password':password
},
success: function(data){
window.location.href = data['url']
}
})
})
$('.destinationsButton').click(function(){
var url="/destinations";
window.location=url;
})
}); })(jQuery);
I have attached the link to the html page which contains the second script.
Link to Page
If you go to this link, there is an image:
When I click on Login button, the click function runs multiple times before control goes to other function. I want the click function to run single time and then control should go to other function.
I tried e.stopPropagation but in case of a popup on same page, the popup does not open. Here on clicking on login, popup comes.
Is there any reason you are using the below?
jQuery('*').on("click",function(e){});
I think this might work better
jQuery('body').on("click",function(e){});
good luck
I don't know where you're stuck but you may use one to run the click function just once:
$(selector).one('click',function(){
//code runs only one click
});
On a page with a tab control, each tab contains a table, each tr contains a td with a button which has a value assigned to it.
<td>
<button type="button" class="btn" name="deleteEventBtn" value="1">Delete</button>
</td>
This code below works for the first delete. After the AJAX call & the refresh of the div, no further delete buttons can be clicked. The .on is attached to the document. The same happens if I attach it to the body or anything closer to the buttons.
function deleteRecord(url, id, container) {
$.ajax({
type: "POST",
url: url,
data: { id: id },
success: function (data) {
$('#delete-popup').hide();
$(container).trigger('refresh');
}
});
}
$(document).ready(function () {
$(document).on('click', '[name^="delete"]', function (e) {
e.preventDefault();
var id = $(this).val();
$('#current-record-id').val(id);
$('#delete-popup').modal('show');
});
$('#delete-btn-yes').on('click', function (e) {
e.preventDefault();
var recordId = $('#current-record-id').val();
var recordType = location.hash;
switch (recordType) {
case "#personList":
deleteRecord(url, recordId, recordType);
break;
}
});
});
Any ideas? Could it be related to the wildcard for starts with [name^="delete"]? There are no other elements where the name starts with 'delete'.
EDIT
When replacing
$(container).trigger('refresh');
with
location.reload();
it "works", however that refreshes the whole page, loses the users position and defeats the point of using AJAX.
As the button click is firing at first attempt, there is no issue in that code. All you have to do is, put the button click event in a method and call it after the refresh. This way, the events will be attached to the element again. See the code below,
function deleteRecord(url, id, container) {
$.ajax({
type: "POST",
url: url,
data: { id: id },
success: function (data) {
$('#delete-popup').hide();
$(container).trigger('refresh');
BindEvents();
}
});
}
$(document).ready(function () {
BindEvents();
});
function BindEvents()
{
$(document).on('click', '[name^="delete"]', function (e) {
e.preventDefault();
var id = $(this).val();
$('#current-record-id').val(id);
$('#delete-popup').modal('show');
});
$('#delete-btn-yes').on('click', function (e) {
e.preventDefault();
var recordId = $('#current-record-id').val();
var recordType = location.hash;
switch (recordType) {
case "#personList":
deleteRecord(url, recordId, recordType);
break;
});
}
Apologies to all and thanks for your answers. The problem was due to the way the popup was being shown & hidden.
$('#delete-popup').modal('show');
and
$('#delete-popup').hide();
When I changed this line to:
$('#delete-popup').modal('hide');
it worked. Thanks to LShetty, the alert (in the right place) did help!
If you are using Bootstrap Modal
After Ajax Request before Refreshing page add
$('.modal').modal('hide');
This Line will Close your Modal and reload your page. Before that it will complete all Ajax Request things.
But for google chrome there is no issues :) hope this help someone.
I am trying to do an ajax pagination with the following code:
// AJAX pagination
$(".pages .prev").live('click', function(event) {
event.preventDefault()
var current_page = parseInt(getParameterByName('page'))-1;
$.get('/ajax/financial_page/', {'page': current_page}, function(response) {
$(".content table").replaceWith(response)
});
})
And in my view function:
def financial_page(request):
"""
Returns a single financials page, without extra HTML (used in AJAX calls).
"""
page = int(request.GET.get('page', 1))
if request.user.is_superuser:
fs = FinancialStatements.objects.order_by('-date', 'statement_id')
else:
up = request.user.get_profile()
providers = up.provider.all()
fs = FinancialStatements.objects.filter(provider__in=providers).order_by('-date', 'statement_id')
fs_objects, current_page_object, page_range = paginator(request, objects=fs, page=page, number_per_page=30)
data = { 'fs':fs_objects,
'page_range': page_range,
'current_page': current_page_object,
}
page = render_to_string('financial_section.html', data, RequestContext(request))
return HttpResponse(simplejson.dumps([page]))
However, there are two problems I'm running into. The first is that the response is not really HTML, and has a bunch of n\t\t\n\t\t\n\t\n\t\n\t\n\t\t\n\t\, etc. Also, I'm having trouble keeping track of the current page/changing the url as needed. How would I build a functional ajax pagination here?
Update: I figured out the first one, by doing response = $.parseJSON(response);. How would I keep track of which page I am on though?
To keep track of the page, you can increment/decrement a variable on click with your AJAX function. Try this:
var counter="0";
$(document.body).on('click', ".pages .prev, .pages .next", function(event) {
if($(this).hasClass('prev')
counter--;// <--decrement for clicking previous button
else if($(this).hasClass('next')
counter++; // <--increment for clicking next button
event.preventDefault()
$.get('/ajax/financial_page/', {'page': counter}, function(response) {
$(".content table").replaceWith(response)
});
})
I would also not use live method as it is deprecated as of jQuery 1.7. It has been replace by the on method. See the jQuery on() API here: http://api.jquery.com/on/
Check this tutorial about "Ajax Scroll Paging Using jQuery, PHP and MySQL", it may simplify your job:
http://www.bewebdeveloper.com/tutorial-about-ajax-scroll-paging-using-jquery-php-and-mysql
Here is the essential from:
var is_loading = false; // initialize is_loading by false to accept new loading
var limit = 4; // limit items per page
$(function() {
$(window).scroll(function() {
if($(window).scrollTop() + $(window).height() == $(document).height()) {
if (is_loading == false) { // stop loading many times for the same page
// set is_loading to true to refuse new loading
is_loading = true;
// display the waiting loader
$('#loader').show();
// execute an ajax query to load more statments
$.ajax({
url: 'load_more.php',
type: 'POST',
data: {last_id:last_id, limit:limit},
success:function(data){
// now we have the response, so hide the loader
$('#loader').hide();
// append: add the new statments to the existing data
$('#items').append(data);
// set is_loading to false to accept new loading
is_loading = false;
}
});
}
}
});
});
Try using the javascript String.replace() method:
// AJAX pagination
$(".pages .prev").live('click', function(event) {
event.preventDefault()
var current_page = parseInt(getParameterByName('page'))-1;
$.post('/ajax/financial_page/', {'page': current_page}, function(response) {
response = response.replace(/\n/g,'<br>').replace(/\t/,' ');
$(".content table").replaceWith(response)
});
})
jQuery.get(url, [data], [callback], [type])
type :xml, html, script, json, text, _default。
how about trying to define the last parameter as "html" ?
