I am using cordova 2.2.0 with Xcode 4.5.2. On one of my pages I have a select component and once a particular option is selected I want to display a table within a div. My html looks like this: <div class="hero-unit" id="#facprog"></div>
The javascript/jquery looks like this:
<pre><code>
$(function() {
$('#selFaculty').change(function() {
var facultyName = $('#selFaculty').val();
var progDetails = app.fillFacultyProgramme(facultyName);
alert(progDetails);
$('#facprog').append(progDetails);
});
});
</code></pre>
Note that #selFaculty is the id of the select object. However, when the select option changes, everything in javascript executes except for the append. Nothing shows up in the div. Is there a different way to add html element to a div in jquery under cordova 2.2.0 in iOS?
Thanks in advance,
José
With jquery you can refresh a div.
This is a good example:
<script>
var auto_refresh = setInterval(
function()
{
$('#loaddiv').fadeOut('slow').load('reload.php').fadeIn("slow");
}, 20000);
</script>
and now you need to put the div in the body section of your page
<div id="loaddiv">
</div>
from http://designgala.com/how-to-refresh-div-using-jquery/
and there is another example here:
refresh div with jquery
The first example is useful when you need to load a script and refresh and the second one is useful when you need to make a change, e.g. append html and then refresh as in your case.

I try to make the items of a list draggable, but it doesn't work. jQuery doesn't seem to add the ui-draggable class, or maybe Angular removes it.
Javascript
$('.results_video').draggable({
});
HTML
<div class="results_video" ng-repeat="video in results.list">
{{video.title}}
</div>
Note that if I just write the following html, it works
<div class="results_video"></div>
Any suggestions?
I have found the solution. I need to make these divs draggable after they have been loaded. In my case:
var VideoCtrl = function ($scope){
$scope.$watch('search', function(){
//Some code that updates the divs
$('.results_video').draggable();
});
};
I have a menu header and when you click one of the menu links it directs to another page half way down (which i want) as it finds the relevant div id name. I was wondering if there is a way to clean the url back up again so it doesn't include the #id in my url? Tried window.location hash and this breaks it from scrolling and leaves the # in the url. Here is what i have:
In my menu: <li><a href="about#scroll-to" ....
And on the about page, it scrolls down to a div called #scroll-to..<div id="scroll-to"></div>
Any suggestions would be great. Thanks!
Using jquery, you can make a POST call to the target page when menu is clicked.
The POST data will contain the id of the div where you want to slide to.
On your target page, use your server language (php, asp) to output that id in a js variable and on document ready slide using jquery to that id.
Then you will have a clean url, and the page scrolling to your div.
---- edit: here comes the code!
Lets use jquery to make a POST to the target page, when a menu item is clicked. We will add a class, lets say, "mymenuitem". We will add this class to our link in the menu. So we will have
<li>Information about us</li>
(the onClick stops link from redirecting manually)
and an empty form (put it after the < body >)
<form id="slidinganchorform" method="post" action="YOURTARGETPAGE.HTML"></form>
then we will create the neccessary jquery so when the < a > tag with class "mymenuitem" is clicked, we will make a POST to the target page.
<script type="text/javascript">
jQuery(document).ready(function(){
$(".mymenuitem").click(function() {
// we will split the clicked href's value by # so we will get [0]="about" [1]="scroll-to"
var the_anchor_id_to_scroll_to = $(this).attr("href").split('#')[1];
// lets do the POST (we WILL TRIGGER a normal FORM POST while appending the correct id)
$("#slidinganchorform").append('<input type="hidden" name="anchorid" value="'+ the_anchor_id_to_scroll_to + '">');
$("#slidinganchorform").submit();
});
});
</script>
then in our YOURTARGETPAGE.HTML we will have something like (let's assume we use php)
<head>
<!-- make sure your jquery is loaded ;) -->
<?php
if($_POST['anchorid']!='')
{
?>
<script type="text/javascript">
jQuery(document).ready(function(){
// lets get the position of the anchor (must be like <a name="scroll-to" id="scroll-to">Information</a>)
var thePositiontoScrollTo = jQuery('#<?php echo $_POST['anchorid']; ?>').offset().top;
// Lets scroll
jQuery('html, body').animate({scrollTop:thePositiontoScrollTo}, 'slow');
});
</script>
<?php
}
?>
</head>
be sure the correct id must exist ;)
<a name="scroll-to" id="scroll-to">Information about us or whatever...</a>
(remove your old code because i changed some variable names and it will be difficult to debug if there are parts from the previous version. write everything from the start )
You can do this when the new page loads
history.pushState("", document.title, window.location.pathname);
However it will also remove the query string. Although, you could play with it a little bit to keep it
I have jQuery UI tabs set up, but a problem that I'm having with links to different pages is that they load all contents of the page into the tab. This includes the footer, header, and other navbars that I don't want in the tab. What if I would only like to load a single ID from that page?
My tabs are set up this way:
<div id="mytabs">
<ul>
<li>Awesome page</li>
<li>Foo</li>
</ul>
</div>
Nothing much going on in the jQuery...
$(function() {
$( "#mytabs" ).tabs();
});
Let's say this is the html of "awesomepage" (that the first link targets):
<html>
<head>
<title>awesome page</title>
</head>
<body>
<div id="header">bla</div>
<div id="awesomeness">awesomeness!</div>
<div id="footer">fdsfd</div>
</body>
</html>
...And I only want the tab to load #awesomeness from the page. How would I go about doing this? I've read into some guides that do that by adding a data-target="#youridhere" attribute to the HTML, but I'm still confused on how to implement the javascript. It seems like this is a convenient solution, as I won't be targeting the same ID in every page. Any clues on how to get the javascript working?
Thanks in advance!
The function that allow to load partial code of the response is the $.load() function.
Unfortunately, the tabs() feature does not use this function but use $.ajax instead.
You can try this solution:
You can try to stop the default processing on the beforeLoad callback and manage your ajax call with the $.load() method.
(base on the 1.9 documentation, you may should adapt)
$('#tabs').tabs({
// Callback run when selecting a tab
beforeLoad: function(event, ui) {
// If the panel is already populated do nothing
if (ui.panel.children().size() > 0)
return false;
// Make your own ajax load (with fragment feature)
ui.panel.load(ui.tab.attr('href') + ' #yourFragment');
// stop the default process (default ajax call should not be launched)
return false;
});
NOTICE: I'm not sure about extracting the URL with ui.tab.attr('href'), check before what object is ui.tab, but it should be easy to retrieve the href parameter.
Good luck
Got the solution :) Using one of the answers as a reference point, the tabs can now load a single element specified in the data-target attribute. Here is the modified version:
$(function() {
$('#tabs').tabs(
{
beforeLoad: function(event, ui) {
if (ui.panel.children().size() > 0)
return false;
ui.panel.load($('a', ui.tab).attr('href') + $('a', ui.tab).attr('data-target'));
return false;
}
});
});
I'm building a select list with an Ajax call that is triggered when another select list is changed.
The page loads correctly with the jQuery styling, but when I replace my ajax container with the new div I can't get jQuery mobile to format it. This means that it reverts to the native select list format.
I have tried what is suggested in the JQM documentation:
var myselect = $("select#foo");
myselect[0].selectedIndex = 3;
myselect.selectmenu("refresh");
but that does not work. My page initially loads with this:
<div id="ajax-destination">
<select id="destinationAirport" data-native-menu="false">
<option value="-- Please Select --" data-placeholder="true">-- Please Select --</option>
</select>
and this is my jQuery code wrapped in the change function of the other select list.
$('#ajax-destination').empty();
$.post(url, { departureAirport : departureAirport }, function(data) {
$('#ajax-destination').append(data);
var myselect = $("#destinationAirport");
myselect[0].selectedIndex = 1;
myselect.selectmenu("refresh");
});
The only other way I can think to do this is to return a JSON array via Ajax and use that to add the options to the select list, but I would prefer to just send formatted HTML because it's simpler to follow.
If myselect.selectmenu("refresh"); or myselect.selectmenu("refresh",true); doesn't work you can always refresh the page using
you could try myselect.trigger('create');
#Andy :
myselect.selectmenu("refresh"); will refresh the select box and where as
myselect.selectmenu('refresh', true); will rebuild the select menu.It may helps you out. Check this link once http://forum.jquery.com/topic/how-to-add-items-and-refresh-the-select-menu-in-jquery-mobile
I am developing the application using jQuery Mobile 4.1.
In my app, I have two html pages like login.html and home.html. In the home.html have 3 pages. () like menupage, searchpage, resultpage.
The project flow is login.html ---> home.html. In home.html, menupage is displayed as a first page. If I choose the some option in the menupage it will move to searchpage and then resultpage. consider, currently I am in the resultpage. If I press the back button on the mobile browsers (iPhone-safari, Android-chrome) then it moves to the login.html.
But I want to display the searchPage. How to solve this one? is it possible to do this?
[Note : The pages should be in the single html page(home.html).
use the attribute data-rel="back" on the anchor tag instead of the hash navigation, this will take you to the previous page
Look at back linking: Here
Newer versions of JQuery mobile API (I guess its newer than 1.5) require adding 'back' button explicitly in header or bottom of each page.
So, try adding this in your page div tags:
data-add-back-btn="true"
data-back-btn-text="Back"
Example:
<div data-role="page" id="page2" data-add-back-btn="true" data-back-btn-text="Back">
try
$(document).ready(function(){
$('mybutton').click(function(){
parent.history.back();
return false;
});
});
or
$(document).ready(function(){
$('mybutton').click(function(){
parent.history.back();
});
});
You can try this script in the header of HTML code:
<script>
$.extend( $.mobile , {
ajaxEnabled: false,
hashListeningEnabled: false
});
</script>
You can use nonHistorySelectors option from jquery mobile where you do not want to track history. You can find the detailed documentation here http://jquerymobile.com/demos/1.0a4.1/#docs/api/globalconfig.html
This is for version 1.4.4
<div data-role="header" >
<h1>CHANGE HOUSE ANIMATION</h1>
Back
</div>
try to use li can be more even
<ul>
<li>back</li>
</ul>
