Is there a simple way to show a loading spinner in the body of a jquery UI tab while it is loading via AJAX?
Essentially I am looking for something like the spinner option, but displaying the graphic and a loading message in the tab body rather than the tab title.
This should work with jQuery UI 1.9+ for ajax loaded tabs (assuming your tabs have id 'tabs'):
$("#tabs").tabs({
// loading spinner
beforeLoad: function(event, ui) {
ui.panel.html('<img src="loading.gif" width="24" height="24" style="vertical-align:middle;"> Loading...');
}
});
You'll need to put a loading.gif in the right place and adjust the img tag src, width and height, but I think you get the idea. You can get a bunch of spinner images at http://www.ajaxload.info/

I have some AJAX loading in my app, and I thought it would be nice to have a loading icon, since there's a little delay. I grabbed some code from http://tobiasahlin.com/spinkit. The loading and hiding works fine, except that I have a logo in the header, which is a link to the root:
<%= link_to "#{app_name}", root_url, id: "logo" %>
Clicking the link takes you to the root, but the loading icon is visible. But if you reload the page, the icon is hidden, as desired. So there's something different about clicking the link.
The view:
<div class="spinner">
The CSS does not set the hidden attribute. If I set it, the spinner is always hidden.
The jQuery:
$( document ).ready(function() {
// hide spinner
$(".spinner").hide();
// show spinner on AJAX start
$(document).ajaxStart(function(){
$(".spinner").show();
});
// hide spinner on AJAX stop
$(document).ajaxStop(function(){
$(".spinner").hide();
});
});
I tried adding an onclick even to the logo. That fires first, then the page loads with the spinner visible. Any ideas what's wrong?
Terry, this is an accompaniment to the comment which helped you.
There are several things to fix:
You should keep your CSS hidden, using JQuery to make it visible.
You're currently hiding your spinner on DOM load with JQuery.
Although this will work, it adds unnecessary overhead to your application. Instead, you'll be much better to show the spinner when Ajax runs:
#app/assets/stylesheets/application.css
.spinner {
display: none; /* Use this instead of inline styles */
}
You should bind your spinner to on-page elements
You're currently binding the spinner to ajaxStart & ajaxStop. These are global functions, fired EVERY time Ajax runs.
This may work in a simple application, is bad practice in a more complicated system.
I would do the following:
#app/assets/javascripts/application.js
spinner = function(){
$(".spinner").toggle();
}
$(document).on("ajax:beforeSend", function(){
spinner();
}).on("ajax:complete", function(){
spinner();
});
$(document).on("click", ".element", function(){
spinner();
$.ajax({
...
});
This uses the ajax:beforeSend event handler from Rails UJS (every time you call remote: true, this will fire).
It also allows you to use the spinner function for any other event/element in your app.
This is driving me a little crazy as I just can't get it to work :(!
I have jQuery tabs set-up as follows (all working) :
$(".tabs_area" ).tabs({
fx: { duration: 'slow', opacity: 'toggle' }
});
I then have a scroll to anchor focus mechanism (again works fine in terms of the function itself) :
$('.tabs_area li a').bind('click',function(event){
var $anchor = $(this);
$('html, body').stop().animate({
scrollTop: $($anchor.attr('href')).offset().top
}, 500,'easeInOutExpo');
event.preventDefault();
});
My problem is that sadly they won't work simultaneously. When I click the tab, it correctly displays the corresponding tab content BUT it doesn't scroll you to the start of this content. You have to click the tab again for it to then do the scroll to the content, which isn't good.
Sadly the reason I need is that I am using this on a mobile website, and when you click the tab, although it does actually change the content, it is bellow the tabs menu, and therefore below the visible area of the screen, hence why I want it to swap the content then scroll you down to this so you can see it, and of course with one click only.
So I think I need to combine the scroll functionality within the tabs set-up code... somehow... as a callback or something... but I just keep breaking it :(!!
Any help would be so much appreciated.
Thanks in advance,
TJ
Why don't you use the show option for jQuery Tabs?
Seems to do what you wish to do.
Check the solution
$(".tabs_area" ).tabs({
show: function(e,ui){
$('html, body').stop().animate({
scrollTop: $(ui.tab.getAttribute('href')).offset().top
}, 500,'easeInOutExpo');
}
});
Hello I am using jquery-ui tabs on a page that is being embedded into different platforms. The tabs work fine but the problem is if you click a link in the tabbed page it exits the tabs to goto the page. Is there an option in the tabs call to make them more self contained or should I look into setting the target of the anchors on those pages, etc?
$(function() {
$( "#crmtabs" ).tabs({
cookie: {
expires: 1
},
ajaxOptions: {
error: function( xhr, status, index, anchor ) {
$( anchor.hash ).html(
"Couldn't load this tab. We'll try to fix this as soon as possible.");
}
}
});
});
I'm not sure I understand your issue. Your code will try to load tab content via AJAX so clicking a tab will load the page specified by the anchor in your cmrtabs markup. Remember that UItabs is basically rendering the output of the AJAX loaded page and inserting it into the appropriate container in the crmtabs markup. Any links in the loaded page are now relative to the tabs page (i.e. jQuery code in the AJAX loaded page will not work but jQuery code in the tabs page can operate on the AJAX content). Links in the loaded tab are not "contained" but are rather now a part of the tabs page. If you are thinking of some kind of iFrame behavior within the tab, you are moving beyond the intent of the tabs widget. See this article referenced on the jQuery UI site. http://www.useit.com/alertbox/tabs.html
I'm using the jQuery tabs library to create a set of remote (i.e., ajax loaded) tabs.
However, to avoid the initial page load being empty until the ajax request finishes, I'd like to include the content for the initial tab with the initial page download.
I've got this generally working by providing a div in the initial page load that matches the title of the tab, but even though this content appears immediately, as soon as I initialize the tabs it does the ajax request IN ADDITION which is both wasteful and causes a flicker. My basic question is how can I get jQuery tabs to NOT do an ajax request for the initially selected tab, and get this content as part of the initial page load, while still loading the other tabs dynamically.
The complication is that I can't hard code the ids/hrefs for which tab is the "initial" one since the initial tab will change based on available content.
I'm sure there is some kind of hacky way to do this with javascript rewriting the URLs of tabs dynamically before I initialize the tabs but I'm looking for a cleaner solution.
Any ideas?
Are you using a specific tab control to do this? It's pretty dependent on how your tabs are implemented...
If you want the data to be included without a delayed load, you will have to include it server side.
Give me some more details and I'll see what I can do!
The best way to do it is using server side implementation to add the starting text. In the JQuery documentation the default text it is not loaded through AJAX.
I'm not sure exactly what you are doing but if that is not your case, then a simple boolean "hack" could be used like this:
var initial=true;
Then, in your tabs code:
$('.selector').tabs({
select: function(event, ui) { if(initial) { initial=false; return false; }
});
This will prevent to execute the ajax call the very first time.
There's an option called "spinner" which holds the text, gif-animation or whatever to be displayed.
$( ".selector" ).tabs( { spinner: 'Retrieving data...' } );
I currently use jTemplates to create a rather large table on the client, each row has a button that will open a jQuery UI dialog. However, when I scroll down the page and click on one of those buttons, jQuery dialog will open, but the scroll position get lost and the page jumps back to the top (with the blocking and the actual dialog showing off the screen). Has anyone seen or know what might cause this problem?
Thanks.
Are you using an anchor tag to implement the "button" that pops the dialog? If so, you'll want the click handler that opens the dialog to return false so that the default action of the anchor tag isn't invoked. If you are using a button, you'd also need to make sure that it doesn't submit (by returning false from the handler) and completely refresh the page.
For example,
$('a.closeButton').click( function() {
$('#dialog').dialog('open');
return false;
});
<a class='closeButton'>Close</a>
If your buttons work with an html anchor tag with href="#" replace the href for example by href="javascript:;" or any other method that you use to disable the href. The reason why the scrolling happens is because of href="#" scrolls to the top of your page.
change your code like this
$('a.closeButton').click( function(e) {
e.preventDefault();
$('#dialog').dialog('open');
});
You can try :
scrollTo(0, jQuery("body"));
