I've got an ajax prefilter which defines a success, an error, and a complete function callback onto the jXHR object. During a successful ajax response I first his the success function callback (as expected), and if I throw an error from within this callback I hit the error callback (again, as expected). However, at this point I would assume my complete callback would be called, yet it never is. I ran a sanity test by issuing an ajax request to an undefined URL, which throws a 404, and it triggered my error callback and then my complete callback as expected.
I'll start off by saying I'm a novice developer. I'm building an mvc application and recently started using the jquery hotness. I've set up a right hand nav and bound click events for collapsible panes. Inside one of those divs (action pane) I've bound click events which will open a modal dialog with a form. The form is submitted with $.post(). Then I've used $.get() to refresh several divs with the new content. Once that happens, all of my links begin to fire twice (collapsible panes and the links in the action pane) in ie8 and the latest firefox but not in chrome. I pulled out all the markup and js and put it on a static test site: [URL].
I'm loading a list of elements into mydiv with ajax, I want them to be selectable so I call the UI plugin selectable after the list has loaded.
The list building function produces this:
<div id='mydiv'> <ul id='mylist'> .... </ul>
[Code].....
The problem is, every time I click the link to reload the list via ajax, I get a duplicate selectable event handler created. Should I be removing the old event handlers before reloading the div ? if so, how?
Everything works, as in selectable still works, and only seems to fire once but I get ever growing memory usage in firefox and an ever growing list of event handlers in the firebug script tab. Eventually firefox starts to crawl and I have to restart the browser.
I have verified that the server is returning valid json. My jsonpCallback is called, but neither the success nor the error callbacks are. I'm stumped by this.
I've written some functions that seem to be able to handle parallel AJAX requests. However, I am not sure if they would work under all circumstances.My idea was to create a separate object for each AJAX request in order to bind the right handler function to the appropriate .onreadystatechange. I have used an array to store references to the created objects so that they would not be garbage collected as long as needed (see the lines commented out below). I have noticed, however, that everything works nicely even if I don't save these references -- so, with these lines commented out.
My question basically is whether it is safe to do so, and what prevents these objects from being deleted by the garbage collector. As both the event and the handler function appear to be in the same object, I think it will not stop the garbage collector.
In my code, ajax_req() is called to make a request; it will create the new ajax_abs object whose constructor takes care of the rest.
// ajaxrequests=new Array(); function ajax_abs(method,page,str,dest,todo,myno){ function init(){
[code]....
Furthermore, is it possible to tell the interpreter after the request succeeds, that now it should garbage-collect the object?
I'm using jquery-1.4.2 with PHP. I have a grid of records with a link to a form i'd like to use to edit the row with. The form is built using php, and works as expected when called just using a regular html link.
When the form is called using $(".ajax").click(function(event), the form comes up, but the textarea(s) are messed up; <textarea>Stuff for the text area
I have something that's called with AJAX when the user enters some text [url]. What I want is to execute some javascript within this "frame". If the frame calls something, with say <script type="text/javascript"> document.write('h'); </script> in it, then "h" doesn't appear, and neither does anything besides what would normally be shown if I didn't add that.
like theres two pages.page one calls page two and displays the output of page 2 on page 1 via ajax.now can i click on page 2's output(on page one) and have it execute another javascript function to call AJAX(a third page)
I am using a form validation class I got from the internet. Now I have a main page wherein I have a <div id="form"></div> that, using AJAX, displays other pages with forms like textboxes, etc. for a user to input. Here is the code for my main page:
Code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head>
When the JS file is not working at the time of Ajax files is called. on first time the onmouseover JS is working but , if you call the ajax JS is not working.
As you can see, when the Mousewheel is turned or #up/#down is clicked, the same function is executed but its redundand! is there a way to combine mousewheel turned and click +up/down so that i only have 1 function?
Trying to add new HTML elements to the document using the jQuery append() function it seems it doesn't add event handlers to the newly created elements.jQuery only seems to add these in Internet Explorer:
I have a piece of javascript which does not work as intended. The code is:
var v = document.getElementById('ReportViewer1'); if (v) { v.ClientController.CustomOnReportLoaded = endPoll; }
The endPoll event handler should be added to the list of event handlers for CustomOnReportLoaded. In the code about, it removes all other event handlers and just adds itself. Looking through JQuery i found:
this will add the new event handler to the collection of event handlers already attached to the click event.how do I select the ClientController through JQuery's selectors?
if i use jquery to attach a click or keyup handler to an element, and then later remove that element form the DOM, do i need to clean up/remove the handler first?
which is the recommended way to bind event handlers to elements. Preferably without giving each of them an id. As far as I know, the "classic" way (<input onchange="...">) is considered deprecated and evil. So what is the jQuery way of doing this?
Am I the only person who finds wildly wrong the jQuery behavior of handler invocation for native events on state-changing elements like check boxes and radio boxes?Specifically, when the user clicks a check box or a radio box, the state of the element is changed and then the handler is invoked.However, when I call"click()" on the elements, the handler is invoked *before* the element value is updated. That makes it pointlessly difficult to write handler routines that need to look at the value to know what to do.
I want to use .ajax instead of the following js function so that I can use the event handlers to update the DOM after changing the contents of a jQuery UI tab. What happens now is that the DOM only contains the first loading of the JQuery UI tab (fragment-3 in this example). Once the tab is changed by the displayfrag3 function (a table is rewritten with new <td ids>) the DOM doesn't see any new id tags so "on click" functions using the new ids don't work.
My Call to this Function:
My Attempt at using jQuery .ajax:
What is the call statement for this and how do I pass a variable to it?
Could someone show me the correct jQuery .ajax code and explain how to add the success handler to update the DOM.
I have a simple filmstrip that uses getJSON to return data. The data is an array containing two arrays. The first, is the base path to photos. The second is a list of the photo file names. I am trying to loop through the array of photos and set them in divs. Then I need to attach an event to popup a larger view of the image placed in a dynamically generated div containing the image and initially hidden.
So what I am trying to accomplish is: 1. get JSON data from server. 2. get base image path from json data array 3. get list of images from json data array 4. Loop through list of images, prepend base path and assign to hard coded div. 5. create a dynamically generated div with larger version of same image. 6. Attach hover action to cause a mouse-over action on the hard coded div to popup the dynamically generated div containing the larger version of the image.
My issue is that once my code runs, no matter what image in the filmstrip I mouse over I always get a popup with the last image in it. Here is my code: <script language="javascript"> $(document).ready( function(){ $.getJSON("<?php echo site_url('filmstrip/index');?>", function(data){ var dir = data['dir']; var imgs = data['imgs']; var i =0; .....
is there a way to set up a page so that a event handler function is bound to a DOM object and event but it runs _after_ the browser's default action is complete?
I would like to add an event handler to the submit() method on the form. If the form contains an elemant recaptcha, it should show a recpatcha in a modal, and upon completing that recaptcha, assign the entered captcha to that element to be submitted long the form.
Basically, I would be able to attach the code that renders the modal and the recaptcha form in the .submit event handler.
I was just wondering; if we have multiple form.submit() handlers that we attach to the forms. in what order are they executed? and what if one of the handlers return false - will the others still be executed? What if we add the "preventDefault" call in any of these handlers?
Basically - I need to know how I can make sure that this handler I'm attaching to the form does not interfere with any other handlers that may have been attached to the forms submit event...
I have a function that sends some data to a PHP file for processing, and call a page refresh after that, but it's not working. This is what I have so far:
function Reload() {location.reload() ;} function del(v,m,f){ $.post("system/reject.php", {id: v}) ; javascript:parent.mainFrame.document.location.reload(); }
The function Reload is something else I tried while trying to get it to work but everything I have done so far doesn't work. :(
I want to run a function only if it has been called from lets say another function, is there an event handler for that? I dont want to call the function on document.ready since it will load without being called?
for example, the below function is run when page loads, how do I just run it only when I call it directly, say from another function..
This is not the way I want to handle events. I checked MSDN and it seems to indicate that the first way should work. Is there something I can do to get the first way (event handlers?) to work in IE5?
