  • Getting all selected checkboxes in an array

    - by Click Upvote
    So I have these checkboxes: <input type="checkbox" name="type" value="4" /> <input type="checkbox" name="type" value="3" /> <input type="checkbox" name="type" value="1" /> <input type="checkbox" name="type" value="5" /> And so on. There are about 6 of them and are hand-coded (i.e not fetched from a db) so they are likely to remain the same for a while. My question is how I can get them all in an array (in javascript), so I can use them while making an AJAX $.post request using Jquery. Any thoughts? Edit: I would only want the selected checkboxes to be added to the array

  • Jquery - How to make $.post() use contentType=application/json?

    - by JK
    I've noticed that when using $.post() in jquery that the default contentType is application/x-www-form-urlencoded - when my asp.net mvc code needs to have contentType=application/json (See this question for why I must use application/json: http://stackoverflow.com/questions/2792603/aspnet-mvc-why-is-modelstate-isvalid-false-the-x-field-is-required-when-that) How can I make $.post() send contentType=application/json? I already have a large number of $.post() functions, so I don't want to change to $.ajax() because it would take too much time If I try $.post(url, data, function(), "json") It still has contentType=application/x-www-form-urlencoded. So what exactly does the "json" param do if it does not change the contenttype to json? If I try $.ajaxSetup({ contentType: "application/json; charset=utf-8" }); That works but affects every single $.get and $.post that I have and causes some to break. So is there some way that I can change the behavior of $.post() to send contentType=application/json?

  • Internet Explorer doesn't update file

    - by Leandro
    Hi! I'm using AJAX with PHP to read from a file and update the div's innerHTML. It works on Chrome and Firefox, but not in Internet Explorer. I tried to use: But I think it is useless, since I'm not refreshing the page. if(!$newMsg || $newMsg == "") { // only reading from the file // do nothing } else { $fileData .= "$newMsg"; fwrite($fileHandler, "$newMsg"); } fclose($fileHandler); echo $fileData; Interesting that when it enters the "else" block, it shows the file's content updated. But when it enters the "if" block, it shows the old content.

  • Ajax enabled sorting and paging on grid in ASP.NET 3.5

    - by Ismail S
    Is there any good solution for ajax enabled Grid with pageing and sorting which only brings the required data from database? I mean it should only bring the data from the database which is to be displayed on the particular page number of the grid. I looked at this. It looks good. But I just thought if anyone has created something better using Google's or Yahoo's javascript library or using any good features of asp.net 3.5.

  • click handler after using Ajax

    - by Tom
    I have a site that plays a stream. I perform an AJAX call to the server once a person presses a button. <input type="submit" class="play" data-type="<?php echo $result_cameras[$i]["camera_type"]; ?>" data-hash="<?php echo $result_cameras[$i]["camera_hash"]; ?>" value="<?php echo $result_cameras[$i]["camera_name"]; ?>"> This prints out a bunch of buttons that the user can select. This is processed by the following code: <script> $(document).ready(function(){ $(".play").click(function(){ var camerahash = $(this).data('hash'); var cameratype = $(this).data('type'); function doAjax(){ $.ajax({ url: 'index.php?option=streaming&task=playstream&id_hash=<?php echo $id_hash; ?>&camera_hash='+camerahash+'&format=raw', success: function(data) { if (data == 'Initializing...please wait') { $('#quote p').html(data); setTimeout(doAjax, 2000); } else { if (cameratype == "WEBCAM" && data == 'Stream is ready...') { $('#quote p').html(data); window.location = 'rtsp://<?php echo DEVSTREAMWEB; ?>/<?php echo $session_id;?>/'+camerahash; } else if (cameratype == "AXIS" && data == 'Stream is ready...') { $('#quote p').html(data); window.location = 'rtsp://<?php echo DEVSTREAMIP; ?>/<?php echo $session_id;?>/'+camerahash; } else { $('#quote p').html(data); } } } }); } doAjax(); }); }); </script> The server returns the messages such as Stream is ready.... My problem is that everything is working great except on additional button clicks. Specifically when they get success (video plays) and they exit back out, they don't get any other messages if they click another button. It is as if the click event is not triggered. Do I need to be doing something to the click handler to respond?

  • PHP display progress messages on the fly

    - by XaviEsteve
    Hi everyone, I am working in a tool in PHP that processes a lot of data and takes a while to finish. I would like to keep the user updated with what is going on and the current task processed. What is in your opinion the best way to do it? I've got some ideas but can't decide for the most effective one: The old way: execute a small part of the script and display a page to the user with a Meta Redirect or a JavaScript timer to send a request to continue the script (like /script.php?step=2). Sending AJAX requests constantly to read a server file that PHP keeps updating through fwrite(). Same as above but PHP updates a field in the database instead of saving a file. Does any of those sound good? Any ideas? Thanks!

  • Retain Site Background and Switch Pages?

    - by yar
    I was about to redo a Rails site today using AJAX so that the background could remain in place. Then I thought, "that would be exactly like using frames," and then I thought about SEO consequences and I dropped the idea entirely and took a look around the Web. It turns out that few sites -- except for Google itself, which has the link bar at the top -- are doing this. It doesn't look impossible to do, but it's not exactly easy. Aside from Ajaxing, you have to think about updating the query-string and having SEO-friendly links (that actually don't work, but rather make background requests via Javascript). Will any of the new technologies -- HTML5, perhaps -- solve this problem and allow us to have a Web with background colors (and other static elements) that do not disappear momentarily between page refreshes? On the other hand, why are few devs doing this with current technologies? Is it just not a big deal, too complicated to implement, or....?

  • jQuery .ajax doesn't load Google Adsense

    - by Sahas Katta
    Hey Everyone, Just ran into an odd issue. I have a simple WP loop and instead of regular NEXT/BACK pages, I use a jQuery powered $.ajax get to append the following page to the current page. It works perfectly. However, I choose to insert a Google Adsense unit every 5th story. Unfortunately, the Adsense unit that is brought in with a second, third, or etc page load don't render. Here's my loop: 10 stories per page, Adsense after the 4th one. <?php $count = 0; ?> <?php if ( have_posts() ) : ?> <?php while ( have_posts() ) : the_post(); ?> <?php $count++; ?> <div class="card"> <div class="title"> <a href="<?php the_permalink(); ?>" title="<?php the_title(); ?>"><span><?php the_title(); ?></span></a> </div> </div> <?php if ($count == 4) : ?> <div class="card"> <!-- ADSENSE CODE HERE (Straight from Google Adsense Panel, no tweaks.) --> </div> <?php endif; ?> As for my jQuery script, here's how that looks: $.ajax({ url: nextPageLink, type: 'GET', success: function(data) { $(data).find('#reviews .card').appendTo('#reviews'); }, error: function(xhr, status, error) { $('.loadination').addClass('hidden'); } }); Keep in mind, I just simplified my code to give you guys an example. The code above was just the essentials. All the loading stuff works perfectly. Images, text, links, etc all load just fine. However, the Google Adsense unit doesn't. Any help would be appreciated. Thanks and Happy Holidays!

  • SO style alert header

    - by Zachary
    I apologize if this question is vague, but I want to build a drop down header, very similar to the one on StackOverflow that alerts you whenever you have earned a new badge, or on Twitter whenever a new tweet comes in. I've been looking around on the internet for a tutorial, but I'm having trouble googling exactly what I'm looking for. I assume there is a way to do this in jQuery, or there may be a jQuery plugin for it, but I haven't had any luck finding one. The idea would probably be to make an AJAX request every so many seconds, and if a new alert-worthy item is found, display it for the user. If someone could point me to a resource to learn how to build one, and/or an existing plugin, that would be great.

  • Dependent Dropdown inside Joomla

    - by kernel
    I was trying to implement the Ajax method for deploying dependent drop down select boxes inside Joomla. The Problem is that if you call an ajaxRequest to run a php with the query that populates the second drop down depending on the result of the first, this is out of the joomla framework and you can't use anything from the joomla functions. So I need to copy into the new file all the details of my dbase login + to write down the html+php to populate the options. I was thinking whether there is an easier solution to this problem. Maybe the Joomla framework supports something like this. Any ideas?

  • Can you write to a file (on a disk) in JavaScript?

    - by asdfqwer
    I don't wanna come across as a troll, so please excuse my question's demeanor, but I am a novice-intermediate programmer taking a stab at AJAX. While reading up on JavaScript I found it curious that most of the examples I've been drawing on use PHP for such an operation. I know many of you may argue that 'I'm doing it wrong' or 'JavaScript is a client-side language' etc. but the question stands. . .can you write a file in only JavaScript? EDIT: Sorry, just read faq, failed to mention this my first post on Stackoverflow while I hope I'm not sounding argumentative, pompous, or subjective.

  • How do you keep the value of global variables (namely a struct variable) between postbacks?

    - by user3702304
    I'm new to this and have already searched for this with not much luck :( Lets say I have defined a struct array globally and filled the array with data on an Ajax ModalPopupExtender. I then have a ddl_SelectedIndexChanged event that does a postback and seems to recycle my array. Is there a way to fire the ddl_SelectedIndexChanged event to perform some code without doing a postback? Or is there an easy way to make the array of type struct retain it's values? (I am creating a website btw) Thanks in advance...
