I am trying to use ajax to load sometag , but my appended code is not being enhanced by JQM.
I tried $(this).trigger('create') and $(this).trigger('updatelayout') but It still not working.
Then I tried to call ajax by function jquery mobile support: $.mobile.changePage()
my code:
$.mobile.changePage({url:'/', data:'add_new_tag=true', type:'GET'}, 'slide', false, true)
in action index: I render 'index.html'
I have checked it in firebug and see response is right (expected) . But I see nothing change in my browser.
Did I miss something ? I hope to recieve your help . Thank you :D
I have never been able to get the trigger('create') method to work for me either. Maybe someone else *cough (Jasper) can help me out with that part of the answer. I may be able to help you with your changPage code though.
Try this for changePage instead:
$.mobile.changePage( '/',{
data: "add_new-tag=true",
type: "get",
transition: "slide"
});

Since 2 days I'm trying to solve a really strange issue. On first Visit of my rails web app loads a picture, but if you click on Home in the navbar to get to the same page, the picture doesn't load. If you reload the page after this, it appears again.
For you to see yourself
I am totally clueless on how to solve this and whats the cause..
You use turbolinks.
try to put your js-slider code like this
$(document).on('turbolinks:load', function() {
$( document ).ready(function() {
// your js-slider code here
})
});
or just put this in application.js and require owl-carousel from aplication.js
try to add below code for home link like:
<%= link_to('home', home_path, data: { no_turbolink: false}) %>
I have been trying to implement the autocomplete and have come across a problem that has stumped me. The first time I call .autocomplete it all works fine and I have no problems. If, however, I call it after I have removed some (unrelated) elements from the DOM and added a new section to the DOM then autocomplete does nothing and reports no errors.
Code:-
$.ajax({
type : 'get',
dataType : 'json',
url : '/finance/occupations',
cache:true,
success:function(data){
occupationList = data;
$('.js-occupation').autocomplete({
source: occupationList,
messages: {
noResults: '',
results: function(){}
},
minLength : 2,
select:function(event, ui){
$('.js-occupationId').val(ui.item.id);
}
});
}
});
The background to this page is that it contains multiple sections that are manipulated as the user moves through them. Hide and show works fine and does not impact on the autocomplete. However, if I do the following:-
var section = $('.js-addressForm:last').clone();
clearForm(section);
$('div.addressDetails').append(section);
$('.js-addressForm:first').remove();
Which gives the user the bility to add multiple addresses on the previous section then the autocomplete stops working.
Any suggestions or pointers on something obvious I am missing?
I have tried to put the initialisation of the autocomplete on an event when the element gets focus and it still does not work.
You have to create the autocomplete after all other underlying objects. If you F12, you will see that the list is "visible", however it is below and hidden by all instances created after it.
If you created a div with inputs (one input being the autocomplete), then you create the automplete then the dialog instances, the autocomplete will never show. If you create the dialog then the autocomplete, no problem. The problem is the z-order
I have faced the same issue. For now to fix this, i'm creating widget on the input once input is in focus. It will help you solve the issue.
You can look for the help on
making sure some event bing only when needed
Sample code will look like this
$( "#target" ).focus(function() {
//I don't care if you manipulated the DOM or not. I'll be cautious. ;)
(function() {
$( "#combobox" ).combobox();
$( "#toggle" ).click(function() {
$( "#combobox" ).toggle();
});
})();
// use a flag variable if you want
});
This solved my problem. Hope its the solution you were looking f
I want a popup to open as soon as the page loads but seem to be getting stuck with the spinning wheel.
Here is a fiddler to demonstrate the problem any help would be appreciated.
http://jsfiddle.net/Ohpyx/UGfXG/
The code I'm using is:
$(document).live('pageinit',function(event){
$('#popupBasic').popup('open');
})
This worked for me:
$(document).on('pageinit', '.ui-page',function(event){
setTimeout(function () {
$('#popupBasic').popup('open');
}, 0);//Note the comment below from #Taifun.
})
You had a race condition and this places the popup code at the end of the queue.
Here is a demo: http://jsfiddle.net/UGfXG/6/
Note: I replaced .live() with .on() (the delegated flavor) as the former has been depreciated as of jQuery 1.7.
The .popup('open') needs the $.mobile.activePage, which is set after the pageinit event. The pagechange event seems to be better for popups.
This worked for me :
$(document).on('pagechange',function(event){
$('#popupBasic').popup('open');
})
If you want it just at the first load, use .one :
$(document).one('pagechange',function(event){
$('#popupBasic').popup('open');
})

Hi everyone,
it's now my fourth try to implement history.js in a Rails app. I have one approach that is running quite okay, but the code is so ugly. Today again I looked at the code and thought: How can I make this better, easier, more DRY?!
What I have done so far (and working quite okay, not perfect):
Set remote: true to my links
jquery-ujs fetches the js.erb
My HTML looks like:
<body>
<div id="content">
some content with buttons, etc.
</div>
</body>
The js.erb contains:
History.pushState(
{
func: '$(\'#content\').html(data);',
data: '<%= j(render template: "news/index", formats: [:html]) %>'
},
'test title',
'<%= request.url %>'
);
And then history.js takes the function and gives it the data. So it replaces the content-div with the new generated code. And it also updates the URL. This code I have to put in every(!) js.erb file.
My last thoughts to make it a bit less ugly were:
Set remote: true to my links
When a link gets clicked it fetches some js.erb which replaces the content-div
All links with data-remote="true" will get a ajax:success-handler
On ajax:success the new URL gets pushed to history.js
But there's still one problem within. Then I have JavaScript code:
$(document).on('ajax:success', 'a[data-remote="true"]', function() { ... });
The problem is: ajax:success never fires if I replace the div-tag where the link (that should fire the event) was in.
Maybe someone can solve my problems...
Or is there a better way?
I only use jquery-ujs and pushState, popState.
See my answer here:
https://stackoverflow.com/a/27532946/345996
what about:
History.Adapter.bind(window, 'statechange', function() {
var state = History.getState();
...
});
I'm using the beforeSend event as global listener for all data-remote to change the handle the history of the browser.
I prefer the beforeSend because I want the link to change as soon as it is clicked, regardless of the result of the ajax request...
$(document).bind('ajax:beforeSend', function(event,data){
history.pushState(null, '', event.target.href)
});
This solve your problem because the event is fired before any modification to the DOM is done.
Have you tried turbolinks ?
It will be default in Rails 4.
I am trying to get jQuery.post() to run my php script and then open a jQuery UI dialog with the data that php script returns. Its supposed to come back as a form with a table and a textarea in it. It works great with alert(data); and i get a pop-up with all my data.
The problem starts if i turn off alert(). Now it opens 2 dialogs. One containing only the table, without textarea, and the second one absolutely empty.
What am i doing wrong here? How come all my data shows up in the alert(), but not in dialog? What do i need to do to fix it?
Oh, and do i need to also include $.ajax() before the $.post()?
Thank you.
$.post("/path/to/script.php",
{ id: this.id, value: value },
function(data){
// THIS WORKS
//alert(data);
// THIS DOES NOT WORK
$(data).dialog({
autoOpen: true,
width: 400,
modal: true,
position: 'center',
resizable: false,
draggable: true,
title: 'Pending Changes'
});
}
);
You don't need another $.ajax() call. The $.post() method is a wrapper shortcut to $.ajax(). What might be happening is you may be getting both default behavior and Javascript bound behavior. I'm assuming this $.post action triggered on a click. If so, then at the very end of your $.click() handler you need to return false to prevent default behavior.
$('input[type=submit]').click(function() {
$.post( /* ... */ );
return false;
});
This is how I handle it. I have a empty div and initialize the dialog upon document ready. Now on the ajax return load that div's html with the data received from PHP and call the "open" method of dialog. Simple and definitely works.
HTH
Ah! This was not a problem with the JS, but my php file.
The textarea was sitting outside of <div>blah blah</div>.
Problem solved.
