I have a JQUERYUI Dialog in a popup page. I want this Dialog to be opened as a new window ( like window.open) Is this possible ??
Don't use jquery dialog at all, it's just a floating div with higher z-index.
<script>
function nWin() {
var w = window.open();
var html = $("#toNewWindow").html();
$(w.document.body).html(html);
}
$(function() {
$("a#print").click(nWin);
});
</script>
<div id="toNewWindow">
<p>Your content here</p>
</div>
Open

fellows! I'm doing some frontend work using doT.js for generating content and jquery-ui for displaying tooltips.
{{##def.defboardtooltip:
<div class='tooltip'>
<!-- some html code -->
<a id='bdetails' href='#'>Click for details</a></div>
</div>
#}}
And how it is used:
<div class="participant" title="{{#def.defboardtooltip}}">
I'm trying to add the event to the a element with jquery as such ():
$(document).ready(function () {
// ...enter code here
$('#bdetails').click(function (e) {
// some code
console.log('fired');
});
});
And I never see the "fired". I'm confused.
jQuery Event delegates are your friend here.
Try:
$(function()
{
$(document).on('click', '#bdetails', function(e)
{
var a = $(this);
});
});
This will filter the event to just your #bdetails element, you can use any valid jQuery seletor here also; e.g., 'a' to delegate all anchor tag clicks.
I have a multipage mobile app using phonegap, leaflet and jquery(-mobile) and the following problem:
On page1, when clicking on a map-marker, the name of the poi is written to localstorage and then page2 is called:
var onMarkerClick = function(e) {
akt_poi = e.layer.options.poi;
var globVars = {
"akt_poi": akt_poi,
};
localStorage.setItem('globalVariables', JSON.stringify(globVars));
window.location = '#page2';
};
On page2 i'm doing the following:
<div data-role="content">
<div id=poi></div>
<script type="text/javascript">
var gV = JSON.parse(localStorage.getItem("globalVariables"));
var a_poi = gV.akt_poi;
document.getElementById("poi").innerHTML='<h2>'+a_poi+'</h2>';
</script>
The correct value is shown only at the first call. When doing another click on a map-marker of page1 the old value instead of the locally stored one is shown on page2 until doing a page-refresh.
What can i do display the right value?
I solved the problem by using sessionstorage:
setting on page1:
var onMarkerClick = function(e) {
akt_poi = e.layer.options.poi;
sessionStorage.akt_poi=akt_poi;
window.location = '#page2';
};
reading on page2:
<div data-role="content">
<div id=poi></div>
<script type="text/javascript">
$('#page_audio').live('pageshow', function(event, ui) {
document.getElementById("poi").innerHTML='<h2>'+sessionStorage.akt_poi+'</h2>';
});
</script>
In a jQuery Mobile application, I'm using Ajax to load a page with dynamic content. Now, I want to add a "reload" button to that page.
Consider index.html:
<div data-role="page" id="home">
<div data-role="header"><h1>Home</h1></div>
<div data-role="content">Time</div>
</div>
And time.php:
<div data-role="page" data-add-back-btn="true" id="time">
<div data-role="header"><h1>Time</h1></div>
<div data-role="content">
<p><?= date(DATE_RFC822)?></p>
Reload
</div>
</div>
I can now navigate back and forth between the "home" and "time" pages, and the time will be updated when arriving on the "time" page, but I would like the "Reload" button to reload the "time" page. That is: it should do an Ajax request for time.php, and recreate the "time" page from the response (and meanwhile show the "page loading" indicator).
How can I do that?
After looking at the code of changePage and loadPage I came up with a simpler solution:
$('.reload').live('click', function(e) {
$.mobile.changePage($.mobile.activePage.jqmData('url'), {
reloadPage: true,
changeHash: false,
transition: 'none'
});
e.preventDefault();
});
Note that JQM will still transition between the old version of the page and the new version; it is best not to use a transition that has a stronge sense of direction (like 'slide').
The preventDefault does not seem strictly necessary, but I added it for good measure.
This does not seem to be possible when using the hijax-style links. You can however use a multi-page HTML document and load the dynamic page content yourself in the pagebeforechange event.
So in index.html, I already add the "time" page with empty content:
<div data-role="page" id="home">
<div data-role="header"><h1>Home</h1></div>
<div data-role="content">Time</div>
</div>
<div data-role="page" data-add-back-btn="true" id="time">
<div data-role="header">
<h1>Time</h1>
Reload
</div>
<div data-role="content"></div>
</div>
Next, I intercept the pagebeforechange event: in case of the "time" page, we will load the page content from URL time.php.
$(document).bind('pagebeforechange', function(e, data) {
if(typeof data.toPage == 'string') {
var u = $.mobile.path.parseUrl(data.toPage);
if(u.hash == "#time") {
loadPageContent($('#time'), 'time.php', data.options);
e.preventDefault();
}
}
});
Since I want to wait for the Ajax request to come back before changing the page, I prevent the page change; loadPageContent will have to do this.
I can do a similar loadPageContent for the "Reload" button:
$(document).ready(function() {
$('#time .reload').bind('click', function(e) {
loadPageContent($('#time'), 'time.php', undefined, $(e.target).closest(".ui-btn"));
});
});
This is the code of loadPageContent:
function loadPageContent(page, url, options, button) {
if(typeof button != "undefined")
button.addClass($.mobile.activeBtnClass);
$.mobile.showPageLoadingMsg($.mobile.loadingMessageTheme, $.mobile.loadingMessage, $.mobile.loadingMessageTextVisible);
var content = page.children(':jqmData(role=content)');
content.load(url, function(response, status, xhr) {
if(status == "success") {
page.page();
content.trigger('create');
$.mobile.hidePageLoadingMsg();
if(typeof button != "undefined")
button.removeClass($.mobile.activeBtnClass);
$.mobile.changePage(page, options);
} else {
$.mobile.hidePageLoadingMsg();
$.mobile.showPageLoadingMsg($.mobile.pageLoadErrorMessageTheme, $.mobile.pageLoadErrorMessage, true);
setTimeout(function() {
$.mobile.hidePageLoadingMsg();
if(typeof button != "undefined")
button.removeClass($.mobile.activeBtnClass);
}, 1000);
}
});
}
This is already quite an elaborate version: it will display the page loading message, and it will display an error message for 1s when the request fails. At the end of a successful request, it will enhance the content with the create trigger, and it will do the page change. If the reload button is passed along, it will mark this button as active while the operation is in progress.
Here is some javascript that I wrote that attempts to change the theme of the header of my jQuery Mobile application. It is in the head element of my web page after jQuery mobile javascript and CSS has loaded.
$(function() {
$("[data-role='header']").attr('data-theme', 'b');
});
Why is it having no effect?
As it turns out, dynamically changing the theme of a header is easy since there is only a single class to change, that goes for buttons as well (if you have buttons in your header).
//store all the classes to remove from elements when swapping their theme
var removeClasses = 'ui-bar-a ui-bar-b ui-bar-c ui-bar-d ui-bar-e ui-btn-up-a ui-btn-up-b ui-btn-up-c ui-btn-up-d ui-btn-up-e';
//when a specific page initializes, find links in the body and add an event
//handler to the click event for them to update the header's theme
$(document).delegate('#my-page', 'pageinit', function () {
$(this).find('a').bind('click', function (event) {
//get the new theme letter, stored in the HREF attribute of the link
var newTheme = $(this).attr('href');
//change the header's class/attr to relfect the new theme letter
$.mobile.activePage.children('.ui-header').attr('data-theme', newTheme).removeClass(removeClasses).addClass('ui-bar-' + newTheme).children('h1').text('My Header (' + newTheme + ')');
//change the header button's classes/attr to reflect the new theme letter
$.mobile.activePage.children('.ui-header').children('a').removeClass(removeClasses).addClass('ui-btn-up-' + newTheme);
return false;
});
});
Here is a demo: http://jsfiddle.net/jUgLr/1/
After all that I guess I should make sure you know you can just add a data-theme attribute to any element to change it's theme:
<div data-role="page">
<div data-role="header" data-theme="e">
...
</div>
<div data-role="content" data-theme="d">
...
</div>
</div>
This would work
$(document).delegate('[data-role=page]','pageinit',function(){
$('[data-role=header]').attr('data-theme','b').removeClass().addClass('ui-header ui-bar-b');
});
I wrote like there: http://jqueryui.com/demos/tabs/#...follow_a_tab.27s_URL_instead_of_loading_its_content_via_ajax
<script type="text/javascript">
$(function(){
$("#tabs").tabs({
select: function(event, ui) {
var url = $.data(ui.tab, 'load.tabs');
if( url ) {
location.href = url;
return false;
}
return true;
}
});
});
</script>
<div id="tabs">
<ul>
<li>
Home
</li>
<li>
About
</li>
</ul>
</div>
Tabs are created, but initial list (div, ul, li) is visible as well. Another problem: when I hover over tab, I see URL kind of /default.htm#ui-tabs-1, /default.htm#ui-tabs-2 etc. But I want to see URL "/default.htm" over the 1st tab and URL "/about.htm" over the 2nd tab.
What could I do to solve my problem?
UPDATE
In version 1.9 there is powerful widget "menu".
You are miss interpreting the jQuery UI Tabs.
This Tabs are for having content hide/show and if using ajax pull the page info and show it on demand.
if you want those tabs to act as a menu ... then you need a menu, not the jQuery UI Tabs.
If your idea if to use this tabs but to fetch the /about.htm as a new content, then you can use the ajax example
http://jqueryui.com/demos/tabs/#ajax
keep in mind that it will fetch the entire content, so the /about.htm page should not have <html> neither <body> tags
I don't want to encourage you to do this, but the solution is currently available on jQuery UI's website: http://jqueryui.com/demos/tabs/#...follow_a_tab.27s_URL_instead_of_loading_its_content_via_ajax
You may extend it a bit to follow only certain URLs:
select: function(e, ui)
{
var tab = $(ui.tab);
var url = $.data(ui.tab, 'load.tabs');
if(url && tab.attr('data-ajax') == 'false')
{
location.href = url;
return false;
}
return true;
}
Then, when defining tabs:
<li>...</li>
