I'm developing a phonegap app with the help of JQuery mobile that has four sections, each one has its own html file. The problem is, for instance, if I first load main.html and then navigate to list.html through a link, the listview in list.html does not show anything, but if I load list.html as the first page, it works perfect, I found this problem while testing on devices. Hope someone can help me fix this
Got this files as an example

});
});
When using Ajax navigation, then jQM loads only the contents of the response's body element (or more specifically the data-role="page" element). The scripts and styles inside the head tag won't execute unless the page is requested via HTTP. This explains why the listview is displayed properly when the page is loaded as first page.
In conclusion there are two possible solutions to your issue:
Initially, replace $(document).ready(function(){ with $(document).on('pageinit', '#vehiculos', function(){ inside vehiculos.js. This action is required, regardless of which of the below solution you will select.
The first solution is to add the vehiculos.js script inside the main.html page's head tag:
<script src="vehiculos.js"></script>
The second solution is to include the vehiculos.js script inside the list.html page's div:
<div data-role="page" id="vehiculos" data-add-back-btn="true">
I hope this helps.

I have a file, which needs to have 90 modals with lots of long texts, because I need to create a modal when a link is clicked.

$(function(){
$('a').click(function(){
var link = $('#name').html(); // I need sent this to my calculator file
$.ajax({

});
});

</div>";
}
echo create_modal();
?>
The result is, I need to click on the link two times to show my modal. But it can't close or does anything.
Where did it go wrong? And is there any way to make my idea better?
you can add
success : function (a){
$('#result').html(a);
$('#myModal').modal('show');
}
just add $('#myModal').modal('show'); when ajax load your modal in #result
I don't think 90 modals is a good idea.
Try saving data maybe in a databas.
Assign your links different ids.
Use jquery to listen to click events
Get data from your server
Populate modal with values from the server.
Check this stack overflow link.
Let me know if you need help
Page is redirecting to a new page(view) even though i set the view response(AJAX Call) to a div class on the same page. Ajax call was successful and i could see the response in console.

I am using ajax to auto refresh a div tag using this code in my index.php file:
<script type="text/javascript">
$(document).ready(function() {
$.ajaxSetup({ cache: false });
setInterval(function() {
$('#messanges').load('messanges.php');
}, 1000);
});
</script>
<div id="messanges"></div>
<textarea name="chat_input" id="chat_input"></textarea>
In messanges.php I have a auto scroll down code.
Cause I want it to start at the bottom when entering the chat.
<head>
<script>
var chat_height = $('#chat').outerHeight();
$('#chat_box').scrollTop(chat_height);
</script>
</head>
<div id="chat_box" style="height:700px; overflow:auto">
<div id="chat">
<div id="Name">Test user:</div>
<div id="img"><img src="picture.png" /></img></div>
<p class="triangle-isosceles left">
"Test" </p>
</div>
The code is now forcing the scroll to stay at the bottom because of the ajax auto refresh.
How can I make it auto refresh, but if I want to scroll up it will not force me down when it refresh?
try some like this
<head>
<script>
var chat_height = $('#chat').outerHeight();
if($('.doScroll').is(':checked'))
{
$('#chat_box').scrollTop(chat_height);
}
</script>
</head>
<input type="checkbox" class="doScroll" checked />
<div id="chat_box" style="height:700px; overflow:auto">
<div id="chat">
<div id="Name">Test user:</div>
<div id="img"><img src="picture.png" /></img></div>
<p class="triangle-isosceles left">"Test" </p>
</div>

When I enter special character as content as pass it to Ajax call I am getting an error :( Ajax call works fine with out any special characters...
Is there any way to encode the data before passing it to ajax call???Please help me on this...
Thanks in advance.
(1.)Either you should put your data into a form and serialize it and then send to the server
(2.)Second way is you can use the js inbuilt function encodeURIComponent().
I am trying to implement photoswipe inside my jquerymobile application.
I am using jquerymobile & Django to develop my application and now I want to setup a gallery on one my pages.
Basically I have 3 pages, page 1 is the the category index, then I got a subcategory index for each category and finally I goto a detail item page.
On the itemPage I put the code to handle the photoswipe library however it doesn't work as I expected because the content of the page is loaded via ajax ( I have to do a full refresh in order to load the photoswipe scripts)
I know I can solve the issue, calling the subctageory level links with rel="external", but this cause a total refresh on Itempage and I want to keep the smooth transitions between pages.
So I need to know how to setup the code for photoswipe before page load.
The code below is from the itemPage level( I put the code from the photoswipe demo inside)

I put the script to handle the gallery inside <div data-role="page" id="Home">
since If I put the code in the head is never executed for the ajax call.
However when I executed the code above, the page doesn't show the last level(itempage never appears)
I guess the problem can be fixed changing ther way the page is loaded with some code like below inside <div data-role="page" id="Home">
$( document ).delegate("#Home", "pagebeforecreate", function() {
alert('A page with an ID of "aboutPage" is about to be created by jQuery Mobile!');
});
but how I can call the photoswipe script, If I replaced the code from alert function with
(function(window, PhotoSwipe){
document.addEventListener('DOMContentLoaded', function(){
var
options = {},
instance = PhotoSwipe.attach( window.document.querySelectorAll('#Gallery a'), options );
}, false);
}(window, window.Code.PhotoSwipe));
it doesn't work? the page doesn't load
Hope you can help me!
Thanks
You should take a look at the examples provided by Photoswipe and how they are initializing photoswipe in their sample galleries.
I'm using this, which also ensures you can call more than one photoswipe-gallery on a multipage and also allows different HTML containers for the images. Feel free to modifiy to your need:
(function (window, $, PhotoSwipe) {
// still using live for photoswipe vs. on()/off()
$('div:jqmData(role="page")').live('pageshow', function (e) {
var currentPage = $(e.target),
options = {},
// allow multiple galleries
swipesOnPage = currentPage.find('.photoswipeable');
// no photoswipe, we're done
if (swipesOnPage.length == 0) {
return false;
}
// if there are swipes init each
swipesOnPage.each(function (i) {
// make sure swipe is initialized once in case events bubble
if ($(this).data('photoswipe') != 'init') {
$(this).data('photoswipe', 'init');
// init - make sure you add a class of swipeMe to your images!!
var photoSwipeInstance = $(this).find(":not('.cloned') a.swipeMe", e.target).photoSwipe(options, currentPage.attr('id'));
}
return true;
});
// un-init when leaving the page
}).live('pagehide', function (e) {
var currentPage = $(e.target),
photoSwipeInstance = PhotoSwipe.getInstance(currentPage.attr('id'));
if (typeof photoSwipeInstance != "undefined" && photoSwipeInstance != null) {
PhotoSwipe.detatch(photoSwipeInstance);
}
return true;
});
}(window, window.jQuery, window.Code.PhotoSwipe));
Add data-ajax="false" to the page calling the sub pages.
Similarly, add to index.html to link to portfolio.html.
If you have a slide show on home page add to link on portfolio.html for index.html as well.
