Something in my script is breaking IE.
I'm looking on a collection of links with a class, and hijacking the URL's.
Clicking a link will animate the height and reveal a message. It also
does an ajax request to mark the message as read.
However, in IE it simply goes to the URL instead of staying on the page and processing the http request.
$('.message .subject .subject_link').click(function(e) {
toggle_message(e)
return false;
});
function toggle_message(m) {
var link = m.target;
var parent = $(link).parent().parent();
console.log(link.href);
$.ajaxSetup({
url: link.href,
dataType: 'json',
timeout: 63000,
type: 'GET',
cache: false
});
if($(parent).hasClass('unread')) {
$(parent).addClass('read').removeClass('unread');
$.ajax({
complete: function(r, textStatus) {
console.log(r.responseText)
}
});
}
if($(parent).find('.body_wrapper').hasClass('collapsed')) {
$(parent).find('.body_wrapper').addClass('expanded').removeClass('collapsed');
$(parent).find('.body_wrapper').animate({
height: 'toggle'
})
} else {
$(parent).find('.body_wrapper').addClass('collapsed').removeClass('expanded');
$(parent).find('.body_wrapper').animate({
height: 'toggle'
})
}
}
any ideas what's causing this issue?

Adding
e.preventDefault();
before toggle_message in the first function should work, although return false should as well.
I don't have access to IE right now but I think you could try preventing the default click event to fire in your click()-function like so:
$('.message .subject .subject_link').click(function(e) {
toggle_message(e)
e.preventDefault();
});
More on .preventDefault() here: http://api.jquery.com/event.preventDefault/

I already asked some questions about ajax, but I still don't get it.
I took a script that I found on the internet and made some modifications, but it didn't work!
HTML:
<a data-toggle="team" id="times">TEAM</a>
ORIGINAL SCRIPT:
<script>
// THIS IS WHERE THE MAGIC HAPPENS
$(function() {
$('nav a').click(function(e) {
$("#loading").show();
href = $(this).attr("href");
loadContent(href);
// HISTORY.PUSHSTATE
history.pushState('', 'New URL: '+href, href);
e.preventDefault();
});
// THIS EVENT MAKES SURE THAT THE BACK/FORWARD BUTTONS WORK AS WELL
window.onpopstate = function(event) {
$("#loading").show();
console.log("pathname: "+location.pathname);
loadContent(location.pathname);
};
});
function loadContent(url){
// USES JQUERY TO LOAD THE CONTENT
$.getJSON("content.php", {cid: url, format: 'json'}, function(json) {
// THIS LOOP PUTS ALL THE CONTENT INTO THE RIGHT PLACES
$.each(json, function(key, value){
$(key).html(value);
});
$("#loading").hide();
});
// THESE TWO LINES JUST MAKE SURE THAT THE NAV BAR REFLECTS THE CURRENT URL
$('li').removeClass('current');
$('a[href="'+url+'"]').parent().addClass('current');
}
</script>
MODIFIED SCRIPT:
<script>
// THIS IS WHERE THE MAGIC HAPPENS
$(function() {
$('#times').click(function(e) {
$("#loading").show();
var href = $(this).attr("data-toggle");
loadContent(href);
// HISTORY.PUSHSTATE
history.pushState('', 'New URL: '+href, href);
e.preventDefault();
});
// THIS EVENT MAKES SURE THAT THE BACK/FORWARD BUTTONS WORK AS WELL
window.onpopstate = function(event) {
$("#loading").show();
console.log("pathname: "+location.pathname);
loadContent(location.pathname);
};
});
function loadContent(url){
$.ajax({
url: 'ajaxcontdent/ajax'+url,
type: 'GET',
error: function(){
// always good to have an error handler with AJAX
},
success: function(data){
$('#content').html(data);
}
// THESE TWO LINES JUST MAKE SURE THAT THE NAV BAR REFLECTS THE CURRENT URL
$('li').removeClass('current');
$('a[href="'+url+'"]').parent().addClass('current');
};
</script>
What is wrong with my script? Nothing happens. I click in my <a> link and nothing. I already tried to put the file location on a hrefattribute, but then e.preventDefault(); doesn't work and my website runs like there is no AJAX.
In the original code, the author use some content.php file. But I don't know JSON, so I have no idea what did he put in that file.
There are no errors in the console.
My ajaxcontent/ajaxteam.php file content:
<p style="color:#fafafa;">Team</p>
It's just one line indeed. Just a test.
I think that may be a cause syntax error, I have regenerate one of your function so please use below code.
function loadContent(url){
$.ajax({
url: 'ajaxcontdent/ajax'+url,
type: 'GET',
error: function(){
// always good to have an error handler with AJAX
},
success: function(data){
$('#content').html(data);
}
});
};
Then use your operation, whatever you want, in your success block of above function.
I hope thin will help you.
Thansk
In your code if I am not wrong
url: 'ajaxcontdent/ajax'+url,
this is the main culprit.
Try this one:
url: 'ajaxcontent/ajax'+url,
this is my first time using ajax. and i don't have an idea where the ajaxStop takes place. I am using the ajaxStart to show a loading image and need the ajaxStop to hide the loading image. Please help.
I have this code to call a popup from "PageOne"
function ShowFixSteps(path, title){
var winHeight = parseInt(jQuery(window).height() - 100);
var winWidth = parseInt(jQuery(window).width() - 600);
jQuery.ajax({
url: path,
success: function(data) {
jQuery("#divPopup").load(path).dialog({
modal: true,
width: winWidth,
height: winHeight,
title: title,
position: "center"
});
}
});
jQuery("#divPopup").bind("dialogbeforeclose", function(){
jQuery("#divPopup").empty('');
});
}
And on my Master page, I have this code to check the start and stop of ajax call:
$(document).ajaxStart(function() {
alert('start');
});
$(document).ajaxStop(function() {
alert('stop');
});
$(document).ajaxError(function() {
alert('error');
});
It alerts the START but not the STOP: no ERROR also.
NOTE: START and STOP alerts are working on Chrome but not IE.
ajaxStop is triggered after all current AJAX requests have completed.
You can read more about ajaxStop using the jQuery API documentation.
You can use .ajaxStop() in the following manner:
$(document).ajaxStop(function() {
$('#loading-spinner').hide();
});
Or you could add :complete callback to your AJAX function, like so:
jQuery.ajax({
url: path,
success: function(data) {
jQuery("#divPopup").load(path).dialog({
modal: true,
width: winWidth,
height: winHeight,
title: title,
position: "center"
});
},
complete: function() {
// do something here when ajax stops
// like hiding the spinner or calling another function
}
});
And as you mentioned how to stop an AJAX request in one of your comments, here's how:
var ajax1 = $.ajax({
type: "POST",
url: "some.php",
...
});
ajax1.abort()
You could check if a specific AJAX request is running before aborting by doing this:
if (ajax1) {
ajax1.abort();
}
Or you could check to see if any ajax requests are running before aborting by doing something like this:
var ajax_inprocess = false;
$(document).ajaxStart(function() {
ajax_inprocess = true;
});
$(document).ajaxStop(function() {
ajax_inprocess = false;
});
if (ajax_inprocess == true) {
request.abort();
}
Beware using .abort() though, as it only stops the client-side code from listening for a response, it wont actually stop the server from working. There are actually a few major caveats using this, so make sure you read about it first.
UPDATED ANSWER FOR UPDATED QUESTION
For IE problem, try using:
$(document).ajaxComplete(function() {
// do something
})
Instead of ajaxStop(). ajaxComplete() will fire each time an AJAX request finishes, rather than when ALL requests have finished using ajaxStop(). Maybe it will help, maybe not.
I have a firework detonation system which uses JQuery to connect to a PHP script via AJAX to detonate the fireworks. The only problem is that if you click one launch button straight after another, there is a possibility of setting off more fireworks than you want.
I need a way to disable all other links on the page until the ajax has finished and received a response. I have tried:
//Prevent clicks
$("body").find("a").click(function (e) { e.preventDefault(); });
//Re-enable clickable links
$("body").find("a").unbind("click");
My current ajax script is:
$(document).ready(function() {
$(".button").on("click",function() {
//Disable all other links
$.ajax({
type: "POST",
url: "launch.php",
data: {FID:$(this).attr('id'),Length:$('#FireLength').val()},
success: function(e) {
//Re-enable other links once ajax is complete
}
});
return false;
});
});
What would be even better is, if the buttons were to grey out whilst waiting for the response. I have a demo script at http://joshblease.co.uk/firework/
One way using a variable disabled
$(document).ready(function() {
var disabled = false;
$('a').css('opacity','0.4');
$(".button").on("click",function() {
//Disable all other links
disabled = true;
$.ajax({
type: "POST",
url: "launch.php",
data: {FID:$(this).attr('id'),Length:$('#FireLength').val()},
success: function(e) {
//Re-enable other links once ajax is complete
disabled = false;
$('a').css('opacity','1');
}
});
return false;
});
});
$('a').click(function(event){
if(disabled)
event.preventDefault();
});
Update
Changed link opacity for a disabled effect.
I would use actual buttons, not links, and disable them when one is clicked. Use a class on the button distinguish it from other buttons that might be on the page.
<input type="button" class="launch" ... >
...
$(document).ready(function() {
$("input[type=button].launch").on("click",function(event) {
// We will handle the button, prevent the standard button press action.
event.preventDefault();
//Disable all other links
$('input[type=button].launch').disable();
$.ajax({
type: "POST",
url: "launch.php",
data: {FID:$(this).attr('id'),Length:$('#FireLength').val()},
success: function(e) {
//Re-enable other links once ajax is complete
$('input[type=button].launch').enable();
}
});
return false;
});
});
Further manage it with a flag as #MonkeyZeus suggests.
I'd manage this with a class (assuming there might be some links you want to work). All the links that you want to not work give them the class blockable.
You can also then style your a.disabled class in your css to grey out the links (or whatever you want)
$(document).ready(function() {
$(a.blockable).click(function(e) {
if($(this).hasClass('disabled'))
{
e.preventDefault();
}
}
$(".button").on("click",function() {
$('a.blockable').addClass('disabled');
$.ajax({
type: "POST",
url: "launch.php",
data: {FID:$(this).attr('id'),Length:$('#FireLength').val()},
success: function(e) {
$('a').removeClass('disabled');
}
});
return false;
});
});
I would approach this by declaring a variable and only allowing AJAX to fire if variable has not been tripped:
$(document).ready(function() {
var launch_processing = false;
$(".button").on("click",function() {
if(launch_processing === false){
launch_processing = true;
$.ajax({
type: "POST",
url: "launch.php",
data: {FID:$(this).attr('id'),Length:$('#FireLength').val()},
success: function(data) {
},
complete: function(){
launch_processing = false;
}
});
}
else{
alert('Are you mad?!?! Fireworks are in progress!');
}
});
});
I am trying to reinitialize a Overlay on new ajax loaded elements.
Here my code:
$('input.search-files').keyup(function(event){
if( event.keyCode == 13 ) {
$.ajax({
type: "GET",
url: ...,
dataType: "html",
data: {...},
beforeSend: function(){
$('.tr-documento').fadeOut('fast', function(){ $(this).remove(); });
$('.table-content').find('.table-loader').show();
},
success: function(data) {
if( $(data).filter('tr').length == 0 ){
$('.table-loader').before( '<tr class="tr-documento"><td colspan="10">Non ci sono</td></tr>' );
} else{
$('.table-loader').before( $(data).filter('tr') );
}
$('.table-content').find('.table-loader').hide();
$("table.table-content").tablesorter({headers: { 0: { sorter: false }, 6: { sorter: false },7: { sorter: false },8: { sorter: false },9: { sorter: false } } });
reInitializeAjaxed();
$(".modifica-file[rel]").overlay();
}
});
}
});
This function is triggered on "ENTER" keyup.
Everything work fine, table sorter works at first hit.
jQuerytools overlay event instead, is binded only at the second hit on "ENTER".
Someone knows this issue?
Is there a way to "live" overlay event and not re-init each ajax call?
I tried this:
$(document).delegate('.modifica-file[rel]', 'load', function(){ $(".modifica-file[rel]").overlay(); });
but is not working..
I think is not opened because the overlay is only initialized without firing.
You can set the load attribute at true like:
$(".modifica-file[rel]").overlay({load: true});
or fire the overlay manually using the load method:
$(".modifica-file[rel]").data("overlay").load();
Docs: http://jquerytools.org/documentation/overlay/
Example: http://jquerytools.org/demos/overlay/trigger.html
I found solution here: http://flash.flowplayer.org/forum/tools/40/21252
There are many solutions on this link, i am using the following:
$(".modifica-file[rel]").live('click', function () {
$(this).overlay().load();
$(this).overlay().load();
return false;
});
I think this is quite dirty solution...$.live() method is not supported anymore on latest jQuery versions...but i am using 1.7.2 and it is working fine!
I added this snippet to end of SUCCESS AJAX callback.
I have a relatively simple jQuery AJAX call wrapped in a function and I am testing my error functionality. The problem I am facing is the AJAX call happens too quickly! It is causing my 'H6' and '.loading' elements to start repeating. The behaviour I require is to remove the elements, then call the ajax.
function getAvailability(form) {
var str = $(form).serialize(),
warning = $('#content h6');
if ( warning.length > 0 ) {
$(warning).remove();
$('<div class="loading">Loading…</div>').insertAfter(form);
}
else
{
$('<div class="loading">Loading…</div>').insertAfter(form);
}
$.ajax({
type: "POST",
url: "someFile",
data: str,
success: function(calendar) {
$('.loading').fadeOut(function() {
$(this).remove();
$(calendar).insertAfter(form).hide().fadeIn();
});
},
error: function() {
$('.loading').fadeOut(function() {
$('<h6>Unfortunately there has been an error and we can not show you the availability at this time.</h6>').insertAfter(form);
});
}
});
return false;
}
I would love to sequence it like so -> Remove 'warning' from page, add .loading. Then trigger AJAX. Then fade out .loading, add & fade in warning/calendar dependent on success.
I have amended my original code, and I have got the function to behave as expected, primarily because I have disabled the submit button during the ajax process.
function getAvailability(form) {
var str = $(form).serialize(),
btn = $('#property_availability');
// Disable submit btn, remove original 'warning', add loading spinner
btn.attr("disabled", "true");
$('.warning').remove();
$('<div class="loading">Loading…</div>').insertAfter(form);
$.ajax({
type: "POST",
url: "public/ajax/returnAvailability1.php",
data: str,
success: function(calendar) {
$('.loading').fadeOut(function() {
$(this).remove();
$(calendar).insertAfter(form).hide().fadeIn();
});
},
error: function() {
$('.loading').fadeOut(function() {
$(this).remove();
$('<h6 class="warning">Unfortunately there has been an error and we can not show you the availability at this time.</h6>').insertAfter(form);
btn.removeAttr("disabled");
});
}
});
return false;
}
I believe that the original sequence was not working as expected due to the time delay created by the fadeOut() functions.
Instead of adding and removing warning, why not just show/hide leveraging ajaxStart and ajaxStop?
warning.ajaxStart(function() {
$(this).show();
}).ajaxStop(function() {
$(this).fadeOut();
});
If you need to sequence your events, then you should try using the deferred and promise methods that are a part of the jQuery.ajax API. This article does a good job of introducing them: http://www.bitstorm.org/weblog/2012-1/Deferred_and_promise_in_jQuery.html
