I have a single page jQuery Mobile app with four "data-role='pages'" in place; so, essentially, it's one HTML doc with four "pages."
Each "page" also has a navigation footer that I am populating dynamically through javascript. I defined a variable called "theFooter," and assigned all my empty footer divs (with classes of "footer") like so:
$('.footer').html(theFooter);
Now, in order to get this to work properly, I have to populate those footers PRIOR to the page being created, otherwise jQuery Mobile won't apply it framework to make the footer bar look like a mobile app nav bar.
So I achieve that through this:
$( "div[data-role='page']").live('pagebeforecreate', function (evt) {
console.log("BEFORE CREATE run."); //writes to my fireBug console to alert me that the 'page' has been run
$('.footer').html(theFooter);
});
It works like a dream, the first time around. Let's suppose the pages are "about," "contact," "mission," and "calendar"…
You click "about"… perfect.
You click "contact".. perfect.
You can do this for each of the "pages," and each time the "pagebeforecreate" is fired and the footer looks GREAT.
HOWEVER, if now you click on, say, "about" again (or any of the ones that you've already visited), the page transitions and the content is in place, but there is NO JQUERY MOBILE FORMATTING. And it is not firing the 'pagebeforecreate' function again, which makes sense, because it has already been created the first time.
I've tried working with 'pageinit' and 'pagebeforeshow' firings, but have gotten nowhere.
I have tried .trigger() and .page() methods… and got nowhere.
Can someone explain exactly how to make that JQuery Mobile formatting stick?
If you call .trigger('create') on the parent element of the widget you can enhance it's markup at any point in time:
$( "div[data-role='page']").live('pagebeforecreate', function (evt) {
console.log("BEFORE CREATE run."); //writes to my fireBug console to alert me that the 'page' has been run
$('.footer').html(theFooter).trigger('create');
});

I am doing my damnedest to embed a Google trends chart into a section of my site.
In theory, it seems easy:
1.) copy script from Google:
2.) Clear a space in your webpage:
3.) Add the code:
<div class="full-row4" style="height: 300px;">
<script type="text/javascript" src="https://ssl.gstatic.com/trends_nrtr/1386_RC02/embed_loader.js"></script>
<script type="text/javascript">
trends.embed.renderExploreWidget("TIMESERIES", {"comparisonItem":[{"keyword":"/m/078rys","geo":"","time":"today 12-m"}],"category":0,"property":""},
{"exploreQuery":"q=%2Fm%2F078rys&date=today 12-m","guestPath":"https://trends.google.com:443/trends/embed/"}
);
</script>
</div>
Seems easy right? wrong!
Every time I do this, I get this result:
Upon further inspection, I found that when those scripts were loaded in, it wipes my entire body of the webpage. (Note: the chart gets loaded in thru an AJAX call containing the entire active page minus the navbars)
I've tried an array of different logic to try and get this to work, but everything I try deletes all HTML in the body tag of the webpage. (script tags are still there)
I found people with a similar issue, but it seems Google has changed how you embed these widgets into a site. Rendering any previous stackoverflow documentation useless. (at least from what I found)
you can use renderExploreWidgetTo() function instead, it takes DOM element as first parameter:
var divElem = document.getElementById('wrapper');
trends.embed.renderExploreWidgetTo(divElem,"TIMESERIES", {"comparisonItem":[{"keyword":"dbs bank","geo":"","time":"today 12-m"}],"category":0,"property":""}, {"exploreQuery":"q=dbs%20bank&date=today 12-m","guestPath":"https://trends.google.com:443/trends/embed/"});
Google trends embed script create an iframe at the hosting website.
Here is a simple example.
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width">
<title>JS Bin</title>
</head>
<body>
<h1>hello</h1>
<div>
<script type="text/javascript" src="https://ssl.gstatic.com/trends_nrtr/1386_RC02/embed_loader.js"></script> <script type="text/javascript"> trends.embed.renderExploreWidget("TIMESERIES", {"comparisonItem":[{"keyword":"dogs","geo":"","time":"today 12-m"}],"category":0,"property":""}, {"exploreQuery":"q=dogs&date=today 12-m","guestPath":"https://trends.google.com:443/trends/embed/"}); </script>
</div>
<h1>world</h1>
</body>
</html>
As you can see, the body is not affected.
The problem is probably not with the trends scripts, but a more general issue.
Try creating an iframe at your page, does it display correctly?
I have a weird issue that i am hoping someone can help resolve.
Problem
When i load html dynamically via .load() function, if any aspect of html in the loaded fragment tries to access the javascript query functions in original HTML page, it doesn't work. Example code below:
Main HTML page (main.html)
<!DOCTYPE html>
<html xmlns:th="http://www.thymeleaf.org">
<head lang="en">
<!--javascript load functions etc... standard header stuff -->
</head>
<body>
<div id="dynamic_section_fragment"></div>
Load Fragment
<script type="text/javascript">
// <![CDATA[
function loadFragment() {
$("#dynamic_section_fragment").load("/api/fragment/");
};
$(".checkvalue").click(function () {
$.getJSON("/api/checkvalue", {term: $(this).attr('value')}, function () {
console.info("submitted for checking");
})
});
// ]]>
</script>
</body>
</html>
FRAGMENT File (fragment.html)
<!DOCTYPE html>
<html xmlns:th="http://www.thymeleaf.org">
<head lang="en">
</head>
<body>
<div th:fragment="check_value">
<br/>
Check the value in the attribute field
<br/>
<a href="javascript:" th:attr="value='123'" class="checkvalue">Check This<a/>
</div>
</body>
</html>
SPRING MVC Controller Method
#RequestMapping("/api/checkvalue")
public String getFragment(Model model) {
return "fragment :: check_value";
}
So a run down of actions:
-Main.html page loads
-User clicks on Load Fragment hyperlink
-Javascript dynamically loads the relevant fragment into the div
-User clicks on Check This hyperlink, nothing happens
Is there something i am missing or something i need to be aware?
It is as if Thymeleaf has preregistered all the possible scenarios of events and doesn't allow any others.
Only way i have been able to get it to work is by injecting the "checkvalue" javascript within the fragment, which as you can agree is a bad way of doing things.
Help is appreciated.
You are applying the click event listener to all existing objects with the checkvalue class.
$(".checkvalue").click(function ()
What you rather wish to do (to make the click event apply to all the existing and any new added, dynamically) is to set a event on a parent in the dom tree (parent both to the existing and to all that will be added).
In your case, the body tag would probably be the safe bet.
The following should suffice:
$('body').on('click', '.checkvalue', function() { ...
Simplified, the code will apply a listener on the body element instead of the .checkvalue objects, and whenever a object with the .checkvalue class is clicked (wether dynamically or statically loaded), the event will fire.
edit
I would also suggest that you, in your javascript, don't use jquery before you know for certain that it is loaded.
The jquery lib have a way of fixing this for you, by using the $( document ).ready() function:
$( document ).ready(function() {
// All jquery dependant code here.
});
In JQuery Mobile 1.4 panels can be external, fixed and responsive which led me to try to create a persistent sidebar using a panel. Everything seems to work great except that the panel is closed every time a page transitions. The panel is then opened again when the new page is shown.
jsfiddle: http://jsfiddle.net/egntp/
I would like for the panel to remain on the page during page transition similar to the way persistent toolbars work.
Any ideas? I looked into the panel's beforeClose() event (http://api.jquerymobile.com/panel/#event-beforeclose) to try to prevent it from closing, but I didn't know how to proceed.

I'm trying to do similar things, playing around with mild success here and there....try starting with this and see how far you can take it...
.ui-panel-closed {
width: 17em !important;
visibility: visible !important;
}
The reason this may work is because all jQuery Mobile is doing when you open or close a panel is they are modifying the css classes of the panel div. One thing they do is toggle a couple css classes, ui-panel-open and ui-panel-closed.
The above css ensures that even though they add the ui-panel-closed class to the panel div, the panel remains open.
You can do this in jQuery mobile 1.4 onwards. Just place the panel outside your page (i.e. data-role="page").
Note that external panels need to be initialized manually. So just do the following:
$(document).on( "pageshow", "[data-role='page']", function() {
$( "your_panel_selector" ).panel({ animate: true });
});
I've got the problem.

If I understood you correctly, you wan to execute some JavaScript when the user clicks on some text.
Wrap the JS in a function, in my example I will call it doSomething().
JS:
function doSomething() {
// your JS (this can be in another file too)
}
HTML:
<span onclick="doSomething()">text</span>
OR:
text
On my site a number of operations can take a long time to complete.
When I know a page will take a while to load, I would like to display a progress indicator while the page is loading.
Ideally I would like to say something along the lines of:
$("#dialog").show("progress.php");
and have that overlay on top of the page that is being loaded (disappearing after the operation is completed).
Coding the progress bar and displaying progress is not an issue, the issue is getting a progress indicator to pop up WHILE the page is being loaded. I have been trying to use JQuery's dialogs for this but they only appear after the page is already loaded.
This has to be a common problem but I am not familiar enough with JavaScript to know the best way to do this.
Here's simple example to illustrate the problem. The code below fails to display the dialog box before the 20 second pause is up. I have tried in Chrome and Firefox.
In fact I don't even see the "Please Wait..." text.
Here's the code I am using:
<html>
<head>
<link type="text/css" href="http://jqueryui.com/latest/themes/base/ui.all.css" rel="stylesheet" />
<script type="text/javascript" src="http://jqueryui.com/latest/jquery-1.3.2.js"></script>
<script type="text/javascript" src="http://jqueryui.com/latest/ui/ui.core.js"></script>
<script type="text/javascript" src="http://jqueryui.com/latest/ui/ui.dialog.js"></script>
</head>
<body>
<div id="please-wait">My Dialog</div>
<script type="text/javascript">
$("#please-wait").dialog();
</script>
<?php
flush();
echo "Waiting...";
sleep(20);
?>
</body>
</html>
You'll need to run that piece of code immediately after your <body> tag, something like:
<html>
<head>
</head>
<body>
<div id="please-wait"></div>
<script type="text/javascript">
// Use your favourite dialog plugin here.
$("#please-wait").dialog();
</script>
....
</body>
</html>
Note I omitted the traditional $(function (){}) because you need this to be loaded as soon as the page is shown, not after the whole DOM is loaded.
I've done this before and works great, even if the page has not finished loading yet.
EDIT: you'll have to be certain the jQuery dialog plugin you're using is loading before your entire DOM loads. Usually this is not the case, you it won't work. In that case, you'll need to use a g'old plain JavaScript solution, such as Lightbox 1 or Lightbox 2.
