I've successfully been able to make elements (like div's, panel's, whatever) draggable by using this bit of Jquery:
<script type="text/javascript">
$(function() {
$(".drag").draggable({ revert: true });
});
</script>
This works fine for anything that already exists on the page before page_load is done and before any postbacks occur. I have a series of buttons (with a class of '.catbuttons') that when clicked, will call out to my database and retrieve some image url's. Once I retrieve this set of url's, I do a for/next loop and create a whole bunch of image objects and place them into a panel. Each of the images has the cssclass of '.drag' to make it work with the JQuery above.
Problem is, they no longer drag! I've read another post on here about needing to rebind javascript stuff after a postback (even a partial postback?) and this would allow brand new controls to get the above Jquery code attached to them, and hence make them draggable. After some google searching, I ran into this and tested it out:
<script type="text/javascript">
$(".catbuttons").live("click", function(){
$(".drag").draggable({ revert: true });
});
</script>
I tried leaving this in the header section of my aspx page with the original script, and also having this here all by itself. No dice either way.
Thoughts?
The above function actually expect a click from user, to call draggable again. Instead you need to do it after postback. Rule here, should be, to register all images with draggable function, after placing the images on page.
Edit:
In your case clicking button just triggers the function to fetch the images. Those images should be placed on page, before you make them draggables. You can register the created object with draggables, immediately after the statements where you place & apply ".drag" cssclass to those object/images at runtime.

I'm using jQuery mobile and my page is generated from an index.php file. When I click on links referring to another option of my php file (index.php?action=other_action) it loads in Ajax so the previous content is still kept in the code. This causes problems as nothing is dynamic anymore, because I'm using specific ids, so it breaks everything. Of course disabling Ajax works but I loose all the beauty of jQuery Mobile.
I guess a solution would be to create an onclick function on the <a>, that will prevent the page from keeping the previous content or delete the old page.
So is there a way to keep using ajax in a way that it doesn't break my dynamic elements ?
You can see it in action here, you can filter names if everything's good. Then click on the top left panel and click something, notice what happens in the inspector...
Thanks for any help.
Hi you have missed enclosing the selector within qoutes...
your jQuery
$(document).ready(function() {
//bind a listener to "click" event on links with class "markviewed"
$('a.ui-btn-present').click(function(event) {
$('ul.listlist').listview('refresh');
$(#pageone).remove(); //<-- selector should be within quotes
// get ids from clicked <a>
var id = $(this).attr('data-id');
$(this).attr({
"class" : "ui-btn ui-btn-icon-notext-ok ui-icon-check ui-btn-a"
});
After much more research I wasn't looking in the right direction: the problem was that the listview had to be refreshed. So I created a new function
<script>
function refreshlist() {
$('.listlist').listview("refresh");
$('#pageone').remove();
};
</script>
And then I added onclick= "refreshlist()"to all my links and now it works.
I am using Popup.js by Toddish.
http://docs.toddish.co.uk/popup/demos/
Long story short, the popup plugin creates divs by default given the classes ".popup_back" and ".popup_cont".
I have another button I wish to press which should completely delete the added divs with those classes after they have been generated and added to the html. As if they never even existed. Surely this is possible?
I have tried running a function which simply runs:
$(".popup_back").remove();
$(".popup_cont").remove();
As shown in this example:
http://www.w3schools.com/jquery/tryit.asp?filename=tryjquery_dom_remove
Unfortunately despite the code running, the actual divs are never deleted as required.
Any ideas? I am new to this kind of thing and have googled around and read a lot about DOM etc but am yet to crack it.
Thanks
EDIT:
In reply to the comments:
The Javascript:
function removePopups() { // This function is called to remove the popups.
console.log("removing...");
$(".popup_back").remove();
$(".popup_cont").remove();
}
function func(url) { // url is the url of the image to be displayed within the popup.
removePopups(); // As soon as the function casillas is called, removePopups is used to remove any existing instances of the divs.
$('a.theimage').popup({ // This is where the Popup plugin is utilised.
content : $(url),
type : 'html'
});
}
The HTML:
<a class="theimage" onclick="func('image/image1.jpg')" href="#" >
Long story short, an image is displayed in the popup.
I think the issue is that the popup plugin runs due to the class but the function func is never actually run when the click occurs. However simultaneously "removing..." still prints out in the console which tells me that the function IS being executed. The problem is I want the popup plugin to run together with the javascript function. Is there a solution for this conflict?
Your implementation should really be as simple as this:
<a class="theimage" href="#" >Open</a>
Bind the popup creation to your popup link:
$('a.theimage').popup({
content : 'image/image1.jpg',
type : 'html'
});
I'm speculating here, but what might be happening is that you're invoking the popup twice by binding the popup() call to a click handler in your markup. The popup plugin already binds the popup creation to a click event.
View working demo. Note the 3 external resource: the popup CSS, the popup JS, and the jQuery JS.
I have 2 divs, they have multiples elements and each element has options(events). In the first div, each element has a button that load, in the second div, the children elements. Those children have a edit button that opens a dialog where the user can edit.
Here is the script:
$("#Content").load("elements.php?id=5", function(){
$.ajaxSetup({cache: true});
$.getScript("../js/elements.js", function(){
$.ajaxSetup({cache: false});
});
})
The problem is: When I load #Content with its script, it`s works good only in the first time, it opens one dialog box, but if I load twice, it opens two dialog boxes, and three, etc.
How do I delete the last script I loaded?
Are there any bindings? any live, etc? I am not sure if its your current code that is causing this issue or the elements.js being that I dont know what is inside of it. I do recommend checking out Jquery stopImmediatePropagation(). I hope this can put you on the right path.
I found this nice jQuery preloader/progress bar, but I cannot get it to work as it is supposed to. The problem is that it first loads my page and after my whole page is loaded the 0%-100% bar displays quickly, after that it reloads my page again. So it does not show the progress bar BEFORE the page loads and it loads the page a second time as well.
Here is my implementation code:
<head>
<script src="js/jquery-1.7.2.min.js" type="text/javascript"></script>
<script src="js/jquery.queryloader2.js" type="text/javascript"></script>
<script type="text/javascript">
$(document).ready(function () {
$("body").queryLoader2();
});
</script>
</head>
<body>
My content...No other reference in here for the Jquery preloader
</body>
Thanks for any help in advance.
I could be very, very wrong here, but in my opinion:
The plugin is flawed.
You have some issue in your page that causes a redirect.
I have created a test fiddle and found out the following:
If there are no images on the page, then the plugin's private function completeImageLoading(); is never called because it is only bound to the image elements. When there are no images -> there's no binding -> no triggering -> nothing completes -> you stay with overlay 0% as demonstrated by the fiddle that is NOT RUN (jsfiddle doesn't see relative images when the page is not run).
The plugin doesn't take into consideration remote images. So if you declare them like so <img src="http://example.com/image.jpg"> - then it won't work because the plugin doesn't recognize them. In fact it is using $.ajax to load images which, obviously, generates a error when trying to access another domain.
The plugin doesn't reload the page (at least in Google Chrome)... check your console output while in the fiddle. It displays the message once per click on Run.
Suggestions:
Make sure you provide at least one relative or background image (though I haven't tested backgrounds...) for the plugin to work.
Show us more code. The fiddle demonstrates that the plugin does NOT cause page reload (at least in Chrome... are you using another browser?). It must be something you made that interferes here.
Specify some options for the plugin (behaves weird when there are none).
Edit regarding preloader
Regarding preloader... if displaying progress is not mandatory for you, then you can just use a window.onload trick. On DOM ready $(...) you create an opaque page overlay with a "Please wait..." message and some animation if you fancy it. Then you wait for window.onload event which "fires at the end of the document loading process... when all of the objects in the document are in the DOM, and all the images and sub-frames have finished loading." When window.onload triggers, you just remove your overlay and voila - the page is ready!
Edit 2 regarding preloader
Actually, you don't even need $(...)... what the hell was I thinking? Just create your overlay (a simple div with a unique id) in your html, style it so that it fills the screen and give it a z-index:1337 CSS attribute so that it covers the entire page. Then, on window.onload:
window.onload = function () {
// Grab a reference to your overlay element:
var overlay = document.getElementById('myOverlay');
// Check if the overlay really exists
// and if it is really appended to the DOM,
// because if not - removeChild throws an error
if (overlay && overlay.parentNode && overlay.parentNode.nodeType === 1) {
// Remove overlay from DOM:
overlay.parentNode.removeChild(overlay);
// Now trash it to free some resources:
overlay = null;
}
};
Of course, it's not really a preloader, but simply an imitation.
Here's a working fiddle you can play with.
P.S. I personally don't appreciate preloaders, but that's just me...
Try out this(Remove the document.ready event and simply call this):-
<script type="text/javascript">
$("body").queryLoader2();
</script>
First of all, here is the site I am working on.
I am trying to get a modal window to pop-up when elements in the Flash are clicked on. Which at this point I have about 90% working when you click on the warrior image. Below is a list of issues I am still trying to solve that I hope you can help me with...
The modal background doesn't fill up
the whole page like it should.
I cannot get the close button to work
I need to set the vidname variable in
both the Flash and Java to load in a
dynamic HTML file. Depending on which
image is clicked on. My naming
convention will probably be something
like vid-1.html, vid-2.html, etc.
If you need to look at the .js file you can view it at /cmsjs/jquery.ha.js
Below is the ActionScript I currently have...
var vidname = "modal.html";
peeps.vid1.onRelease = function() {
getURL('javascript:loadVid(\'' + vidname + '\');');
};
Well I have one for you.
Your current close code is
$('#modalBG, #modalClose').click(function(){
closeModal();
});
If you click the background after a video loads you'll see that the modal does close. The reason your close button does not work is because #modalClose does not exist in the DOM when you are binding to the click function.
You need to either rebind the modalClose element when you modify the DOM or use live. If you use live you just need to change your click code to this:
$('#modalBG, #modalClose').live("click", (function(){
closeModal();
});
