I am using phonegap like this in my application, also note the app is being styled by jquery mobile,
<meta name="viewport" content="width=device-width, initial-scale=1">
<link rel="stylesheet" href="http://code.jquery.com/mobile/1.0/jquery.mobile-1.0.min.css" />
<script src="http://code.jquery.com/jquery-1.6.4.min.js"></script>
<script src="http://code.jquery.com/mobile/1.0/jquery.mobile-1.0.min.js"></script>
<script type="text/javascript" charset="utf-8" src="phonegap-1.3.0.js"></script>
I have this html,
<div id="sync" data-role="page">
<div data-role="header" data-position="inline">
<a data-rel="back" data-icon="back">Back</a>
<h1>Sync</h1>
</div>
<div data-role="content">
<button onclick="sync()">Sync</a></button>
</div>
</div>
I have compiled this for Android and have it working on my Android phone.
But the button there called 'sync' is not always responsive. I click the button and the sync() method doesn't get called every time. I find myself clicking the button a number of times. I can see the button moving when I click it, it is responding by drawing itself being pushed in, but the sync method is not being called.
The sync method starts like this,
function sync()
{
alert("syncing");
$.mobile.loadingMessage = "syncing";
$.mobile.showPageLoadingMsg();
I put the alert in for debugging purposes.
UPDATE:
It has been pointed out that my HTML has an extra tag in it. I have removed it as below but the problem still exists,
<div data-role="content">
<button onclick="sync()">Sync</button>
</div>
I had a similar problem in my application. I tried two different things but I'm not sure wich fixed it.
I added charset="utf-8" in my script tag.
I moved the button click function in to its own script tag. I think there's an error in the other JavaScript block that is preventing the button click function from working when it's in that script block. So you can try isolating the button click JavaScript and see if that helps.
Joke answer: did you push the button hard enough?
Possibly the problem answer:
<button onclick="sync()">Sync</a></button>
^^^^---dangling tag
Is that </a> possibly the cause of the button breaking?

I'm creating an extremely basic script to assist me in one of my google spreadsheets.
I've successfully got a sidebar showing, with a few buttons (which function). However, whenever I click on one of those buttons, it also opens up a new tab, with a URL something like: "https://n-lx3mdv5ls3mdgglsq226llilxd2m4owxy72y3fy-1lu-script.googleusercontent.com/userCodeAppPanel?"
Even if the button is left without any functionality, this still occurs.
Here's an example of the html:
<!DOCTYPE html>
<html>
<head>
<base target="_top">
<link rel="stylesheet" href="https://ssl.gstatic.com/docs/script/css/add-ons1.css">
<!-- The CSS package above applies Google styling to buttons and other elements. -->
<style>
</style>
</head>
<body>
<div class="sidebar">
<form>
<div class="block" id="buttons">
<button id="unindent">Unindent</button>
<button id="indent">Indent</button>
<button id="asdgdgasg">Test</button>
</div>
</form>
</div>
</body>
</html>
How can I stop this new tab from opening every time?
Issue:
<button> type, if not specified defaults to type=submit. So, The form automatically submits the data to the server. This is not preferable in a iframe.
Solution:
Explicitly specify button type as button. <button type='button'>
Use event.preventDefault() to prevent automatic form submission.

Sample Form
When I saw your issue, I thought that this is due to <form>. So I proposed the following modifications.
Modify <form> to <form onsubmit="event.preventDefault()">.
Modify <base target="_top"> to <base target="_self">.
Remove <base target="_top">.
Note:
I think that #TheMaster's answer is more useful information.

The Document Base URL element
I am trying to build a simple webpage that replaces the contents of the <div id="body"> with something new based on the user clicking on a "link"
The following code does exactly what I expect in Chrome and Firefox, but does nothing (except turn the link to the visited color) in IE 10 or 11:
<!DOCTYPE html>
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script>
<script>
$(document).ready(function(){
$("#activities").click(function(){
$("#body").load("test02.html");
});
});
</script>
</head>
<body>
<div id="header">
Activities
<!-- this stays the same -->
</div>
<div id="body">
<p>this is the content that arrives without needing prompting</p>
<!-- All content will be loaded here dynamically -->
</div>
<div id="footer">
<!-- this stays the same -->
</div>
</body>
</html>
This is the content of "test02.html":
<p>---</p>
<p>Hello world!</p>
<p>---</p>
I've checked the javascript security settings in IE and everything is set to "enable." I've also tried adding type="text/javascript" to the script tags.
Some amount of Googling has turned up the possible need to reinstall IE, which I have tried.
Anyone have an idea about how to get this working in IE?
The problem is that IE breaks itself in "compatibility" mode. The way in which it breaks itself in this case is failing to correctly look up your div id="body" element. I think that was observation error on my part, I think the real problem is addEventListener (because jQuery 2.x doesn't fall back to attachEvent anymore, since it doesn't support IE8 and earlier [or the "compatibility" modes that act like them]):
I can replicate the problem. The problem goes away if I tell IE not to break itself (e.g., not to use compatibility mode) by adding this to the top of the head element:
<meta http-equiv="X-UA-Compatible" content="IE=Edge" />
IE's default for intranet sites is to display them in "compatibility" mode.
At one point I wasn't at all sure that when in "compatibility" mode it didn't get confused about that element with the id "body". IE has a history of getting confused by things like that. So you might also consider the-body or similar, but I tested and didn't seem to need it.
Side note: You probably also want to add a return false or e.preventDefault() to your click handler, so it doesn't follow the # link (which will scroll back to the top of the page and add # to the address bar).
add meta tag below to your page
<meta http-equiv="X-UA-Compatible" content="IE=edge;chrome=1" />
Do you mean <body> tag or <div id="body"> and do you ever try preventing default behavior of the link by using this below code :
$(document).ready(function(){
$("#activities").click(function( e ){
e.preventDefault(); //<---- add here
$("#body").load("test02.html");
});
});
I am devloping a phonegap app, I used a multi page template like page1.html, page2.html. Each page hits the server and renders the output and show it in a listview. So the problem is if I hit to redirect from one page to another page means it shows white screen.
And also I tried lot of possible ways when I did the google search. But it not helps for me.
My code is given below:
$('#content').append('<div class="wholediv"><span class = "wholediv_content"><a style="text-decoration:none!important;"href="'+v.pagename+'.html?id='+v.nodeId +'&catname='+ v.pagecat +'" data-ajax="false">'+'<img src="http://www.examole.com/'+image+' " class="eventsimages" alt = "image"/>'+'<br /><p>'+v.pagename+'</p></a></span></div>');
index.html:
<div data-role="page">
<div data-theme="a" data-role="header" data-position="fixed" data-tap-toggle = "false" style="height:45px;">
<h3 id = "title">
Moble
</h3>
<span class="off new_off" id = "off" >Off</span>
</div>
<div data-role="content" id="content">
</div><!-- /content -->
</div><!-- /page -->
</body>
I need to avoid the flickering. Please I did lot of search and applied all those answers it did not help me. If I use data-transition means I need to remove data-ajax="false". What to do?
Double flickering or Double flashing is a well known issue.
The solution posted by Rob is actually what works.
Setting in your mail css file:
.ui-page {
-webkit-backface-visibility: hidden;
}
Use this in your viewport tag aswell:
user-scalable=no
I made a basic template for phonegap. With Jquery mobile and so forth.
http://www.codemonkey.mobi/guides/base.zip
I dont see any whitescreens with my base.
Let us know if this worked for you.
Also try this:

My programming skills are rudimentary at best, so please forgive me if I sound a little clunky discussing these things. I'm learning, but at a chimp's pace.
Here's my issue: I'm using JQuery Mobile to bring in some form content as a dialog via ajax. This content is contained in the document itself, in second div with a data-role="page" attribute.
Within that second page div, I have some javascript that defines a few vars, then writes them into the doc with document.write().
However, when I click the link (the far right link in the nav), instead of popping up a nice dialog, Firefox instead briefly loads a new page with the fist var (not dynamically but as a static page), then redirects back to the starting page, leaving a "wyciwyg(00000)..." in my browser history. Upon said redirect, "WYCIWYG" is displayed in the browser's title bar. Other browsers choke in slightly different ways (Safari doesn't redirect, Chrome displays all the vars and doesn't redirect, etc.), but the WYCIWYG-in-the-history factor is in play in all three. If I remove the document.write commands, the link behaves as expected.
I've scoured the web for hours and not found an answer... similar problems show up in 10 year old Mozilla bug reports, but not much else. The only resolution I've found is not to use document.write() in content loaded via ajax. Unfortunately, I have no clue what the alternative would be, or how I would even begin to execute it. The Javascript code originated at Google - front-end code for a transit trip planner.
Below is some stripped-down code that illustrates the issue. Any guidance would be greatly appreciated, bearing in mind the whole chimp's-pace thing. Thanks in advance.
<!DOCTYPE HTML>
<html>
<head>
<title>WYCIWYG</title>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<link rel="stylesheet" href="http://code.jquery.com/mobile/1.2.1/jquery.mobile.structure-1.2.1.min.css" />

<script>
var startExample = "USC";
var endExample = "201 N Los Angeles St.";
var zip = "90012";
</script>
</head>
<body>
<div data-role="page">
<div data-role="navbar">
<ul data-mini="true">
<li>Service 1</li>
<li>Service 2</li>
<li>PLAN TRIP</li>
</ul>
</div>
</div>
<div data-role="page" id="planTrip">
Some document.write js:
<script>
document.write(startExample);
document.write(endExample);
document.write(zip);
</script>
</div>
</body>
You could simply use jQuery.html() on placeholder elements:
Source: http://jsfiddle.net/fiddlegrimbo/suD6s/6/
Demo: http://fiddle.jshell.net/fiddlegrimbo/suD6s/6/show/light/
<div data-role="page" id="planTrip">
Some document.write js:
<p id="start"></p>
<p id="end"></p>
<p id="zip"></p>
<script>
$("#planTrip #start").html(startExample);
$("#planTrip #end").html(endExample);
$("#planTrip #zip").html(zip);
</script>
</div>
Consider the code given at the end, which makes use of jQuery Mobile to enhance buttons.
The first button (original button) appears when page loads:
The second button (inserted button) is inserted by clicking the yellow box:
The problem here is, the inserted button cannot catch up the CSS styles. This scenario is very common (and not specific to jQuery Mobile) when we work with AJAX, but I have never able to find a solution or workaround for this problem.
What can I do to enhance the inserted button with CSS styles?
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>title</title>
<link rel="stylesheet" href="http://code.jquery.com/mobile/1.1.1/jquery.mobile-1.1.1.min.css" />
<script src="http://code.jquery.com/jquery-1.7.1.min.js"></script>
<script src="http://code.jquery.com/mobile/1.1.1/jquery.mobile-1.1.1.min.js"></script>
<script type="text/javascript">
function insert(){
$("#result").html('<input type="button" value="Inserted button"/>');
}
</script>
</head>
<body>
<form>
<p class="ui-body-e ui-corner-all" style="padding:5px" onclick="insert()">Click here to insert the button</p>
<input type="button" value="Original button" />
<div id="result">
Button not inserted yet
</div>
</form>
</body>
</html>
After you insert the button's html:
$("#result").html('<input type="button" value="Inserted button"/>');
You can call .trigger('create') on its container to invoke the jQuery-mobile renderer on its contents, so your line would look like this:
$("#result").html('<input type="button" value="Inserted button"/>').trigger('create');
jQuery mobile adds extra elements/classes to your objects. This happens onpage load.
When you insert extra buttons or other objects (list,...) the style needs to be applied again.
in this case you use after you inserted the button $(_selector_for_new_button_).button();
jQuery mobile applies the nice button style for you.
