  • return false for parent javascript function

    - by jeerose
    $("#purchaser_contact").live('submit', function(){ $.ajax({ type: "POST", url: 'ajax/contactSearch.php', data: ({ fname: $("#fname").val(), lname: $("#lname").val(), city: $("#city").val(), state: $("#state").val() }), success: function(d) { var obj = JSON.parse( d ); if(obj.result != 0){ $("#contactSearch").remove(); $("#button-wrapper").before('<div id="contactSearch">' + obj.result + '</div>'); $("#contactSearch").slideToggle('slow'); //return false from submit!! }); }); I know there are other posts on this but I couldn't figure out how to apply them properly to my situation without making it messy. How do I return false on the submit event to prevent the form from submitting if I'm within the $.ajax and success functions? Thanks.

  • Tag-like autocompletion and caret/cursor movement in contenteditable elements.

    - by jimeh
    I'm working on a jQuery plugin that will allow you to do @username style tags, like Facebook does in their status update input box. My problem is, that even after hours of researching and experimenting, it seems REALLY hard to simply move the caret. I've managed to inject the <a> tag with someone's name, but placing the caret after it seems like rocket science, specially if it's supposed work in all browsers. And I haven't even looked into replacing the typed @username text with the tag yet, rather than just injecting it as I'm doing right now... lol There's a ton of questions about working with contenteditable here on Stack Overflow, and I think I've read all of them, but they don't really cover properly what I need. So any more information anyone can provide would be great :)

  • Too many open connections... Did I mess up something?

    - by Legend
    I am developing a plugin (for a Bittorrent client named Azureus programmed in Java) that lets me add peers into the current list from which it is downloading. Everything was working fine until yesterday when I started getting these weird errors: DEBUG::Thu Apr 15 10:45:40 CET 2010::org.gudy.azureus2.core3.peer.impl.control.PEPeerControlImpl::addPeer::795: Injected peer 90.35.126.126:33064 was not added - Too many connections DEBUG::Thu Apr 15 10:48:40 CET 2010::org.gudy.azureus2.core3.peer.impl.control.PEPeerControlImpl::addPeer::795: Injected peer 80.25.126.126:33064 was not added - Too many connections DEBUG::Thu Apr 15 10:52:40 CET 2010::org.gudy.azureus2.core3.peer.impl.control.PEPeerControlImpl::addPeer::795: Injected peer 90.35.126.126:33064 was not added - Too many connections I am thinking I messed up something with the TCP sockets. Does anyone know why this could be happening?

  • Unicode data from NSData to NSString

    - by Jeff
    So if I have NSData from an HTTP request, then I do something like this: NSString *test = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding]; This will result in null if the data contains weird unicode data (title is from reddit): {"title":"click..¦¦me..and..then¦¦________ ¦¦check¦¦_.your...¦¦.__...¦¦____ ¦¦....¦¦¦¦¦¦¦¦¦¦¦¦¦¦....¦¦____ ¦¦¦¦¦¦....¦¦¦¦¦¦....¦¦¦¦¦¦____ ¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦____ ....¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦______ ........¦¦..._recently....¦¦________ ....¦¦....viewed....links....¦¦_____"}, How would I convert the data to a string? Ideally, it would best if the string wasn't null so I could parse it as JSON, but even a lossy conversion is fine with me in these cases. I'm not familiar with unicode (naive American I am), so any enlightenment about that would be a nice bonus :)

  • .NET WebService Security who can see and use.

    - by user295734
    Trying to firgure out how to test the security of a WebService. Is there some way to search a site for webservices? I have 2 applications one has a webservice and the other a reference to that service. I let visual studio build the reference in the App_WebReferences folder. The webservice works, but i started wondering, can anyone access this service from any website? If so, how can i test this? How do you search a site for webservices? Could I use jQuery/JSON code from a simple site to access a webservice? I guess if it is not secure, how do you secure a webservice?

    I need to connect to another database in Joomla! that's on another server. This is for a plugin and I need to pull some data from a table. Now what I don't want is to use this database to run Joomla!, I already have Joomla! installed and running on its own database on its server but I want to connect to another database (ON TOP of the current one) to pull some data, then disconnect from that 3rd party database - all while keeping the original Joomla database connection in tact.

  • jQuery.keypad Performance Issues

    - by John Duff
    I am working on a Kiosk Touch Screen application and using the JQuery.keypad plugin and noticing some major performance issues. If you click a number of buttons in rapid succession the CPU gets pegged, the button clicks don't keep up with the clicking and some button presses even get lost. On my dev machine this isn't as noticeable, but on the Kiosk itself with 1 gig of ram it's painful. Trying the demo keypad at http://keith-wood.name/keypad.html#inline the one with multiple targets (which is the case with mine) has the exact same issues. Does anyone have any suggestions on how we might be able to improve this? The Kiosk runs in Firefox only so something specific to that would work. I'm using v1.2.1 of jquery.keypad and just upgraded to v1.4.2 of jquery.

  • Jquery SimpleModal flickers in Firefox

    - by Obay
    I'm using SimpleModal plugin for Jquery and I have a weird problem with Firefox ( other browsers work fine: Chrome, Safari, Opera, IE). What happens is when I click on the button that launches the modal dialog, before showing the modal (and the fadeIn of the overlay), there is a quick "flicker", less than half a second. (It's longer on my slower PC). Weird thing is, it didn't happen in Firefox 3.5.2, but when I upgraded to 3.6.3, I got the flicker. Any ideas? Here is my code: $("#popup").modal({ onOpen: function (dialog) { dialog.data.show(); dialog.container.show(); dialog.overlay.fadeIn('fast'); }, onClose: function (dialog) { dialog.data.hide(); dialog.container.hide(); dialog.overlay.fadeOut('fast', function() { $.modal.close(); }); } });

  • Nested sql queries in rails when :has_and_belongst_to_many

    - by Godisemo
    Hello, In my application I the next task that has not already been done by a user. I have Three models, A Book that has many Tasks and then I have a User that has has and belongs to many tasks. The table tasks_users table contains all completed tasks so I need to write a complex query to find the next task to perform. I have came up with two solutions in pure SQL that works, but I cant translate them to rails, thats what I need help with SELECT * FROM `tasks` WHERE `tasks`.`book_id` = @book_id AND `tasks`.`id` NOT IN ( SELECT `tasks_users`.`task_id` FROM `tasks_users` WHERE `tasks_users`.`user_id` = @user_id) ORDER BY `task`.`date` ASC LIMIT 1; and equally without nested select SELECT * FROM tasks LEFT JOIN tasks_users ON tasks_users.tasks_id = task.id AND tasks_users.user_id = @user_id WHERE tasks_users.task_id IS NULL AND tasks.book_id = @book_id LIMIT 1; This is what I Have done in rails with the MetaWhere plugin book.tasks.joins(:users.outer).where(:users => {:id => nil}) but I cant figure out how to get the current user there too, Thanks for any help!

  • different small js files per page VS. 1x site-wide js file?

    - by Haroldo
    Different pages of my site have different js needs (plugins mainly), some need a lightbox, some dont, some need a carousel, some dont etc. With regards to pageloading speed should i option 1 - reference each js file when it is needed: so one page might have: <script type="text/javascript" src="js/carousel/scrollable.js"></script> <script type="text/javascript" src="js/jquery.easydrag.js"></script> <script type="text/javascript" src="js/colorbox/jquery.colorbox-min.js"></script> and another have: <script type="text/javascript" src="st_wd_assets/js/carousel/scrollable.js"></script> <script type="text/javascript" src="st_wd_assets/js/typewatch.js"></script> option 2 - combine and compress into one site_wide.js file: so each page would reference: <script type="text/javascript" src="js/site_wide.js"></script> there would be unused selectors/event listeners though, how bad is this? I would include any plugin notes/accreditations at the top of the site_wide.js file

  • How can I call some javascript functions but, waiting for the previous has finished?

    - by texai
    I want to call some functions but waiting for the previous one has finished. I know jQuery provides a callback argument in several functions, but I want to learn how implement this behaviour in my own jQuery plugin. So this is the case: After read answers from my previous question I wrote this: (function(callback){ $('#art1').animate({'width':'1000px'},1000); callback(); })((function(callback2){ $('#art2').animate({'width':'1000px'},1000); callback2(); })(function(){ $('#art3').animate({'width':'1000px'},1000); })); But still not working. Three animates still starting at same time. I want they were called one after other. But without using: $('#art1').animate({'width':'1000px'},1000,'linear',function(){ $('#art2').animate({'width':'1000px'},1000,'linear',function(){ $('#art3').animate({'width':'1000px'},1000); }); });

  • CategoryName.find is not a function

    I need to call a plugin inside a ajax call so it could be used on called&received data. But I got the following error. Error: CategoryName.find is not a function Source File: http://www.refinethetaste.com/FLPM/ Line: 82 I tried it as: $.ajax({ dataType: "xml", url: "/FLPM/content/home/index.cs.asp?Process=ViewVCategories", success: function(xml) { $(xml).find('row').each(function(){ var id = $(this).attr('id'); var CategoryName = $(this).find('CategoryName').text(); $("<div class='tab fleft'><a href='http://www.refinethetaste.com/FLPM/content/home/index.cs.asp?Process=ViewVideos&CATEGORYID="+ id +"'>"+ CategoryName + "</a></div>").appendTo("#VCategories"); CategoryName.find("div.row-title .tab").tabs("div.row-title div.panes > div"); }); } });

  • jQuery autocomplete: how to split the string result?

    - by Matt
    I have the following situation with an autocomplete plugin on an .aspx page. It is working fine. The result from the autocomplete search yields a product id and a product description is concatenated with it (i.e. 2099 -- A Product). I know that I need to use split() with this but where do I put it? I'm still rather new to jQuery and javascript. $(document).ready(function() { $('.divAutoComplete').autocomplete("LookupCodes.aspx?type=FC", { mustMatch: true }); });

  • Re-binding an ajaxForm after content re-loads with ajax (jQuery 1.4.2)

    - by Cristian
    I'm trying to figure out why this is a problem when using jQuery 1.4.2 and not 1.3.2. This is my function: function prepare_logo_upload() { $("#logo-upload-form").ajaxForm({ //alert(responseText); success: function(responseText) { //alert(responseText); $('#profile .wrapper').html(responseText); prepare_logo_upload(); } }); } Every other live event works but can't use the .live() method because ajaxForm is a plugin. I have noticed this also for other types of binding (clicks) using the old form (re-binding after callback) Can you tell me if it is a way of solving this? This is a similar question, but due to my newbie reputation here, can't comment or ask a question there, so I'll ask a new one here. - http://stackoverflow.com/questions/2208880/jquery-bind-ajaxform-to-a-form-on-a-page-loaded-via-load Thank you!

  • jQuery-Ui Ajax Tabs bug?

    - by vsync
    I have a JSON that returns from the server which tabs to build, so I init them in my JS like this: $('#tabs').tabs( 'ajaxOptions', { timeout: 20000, error: function(xhr, status, index, anchor){ console.log( status, index, anchor ); } }) .tabs('add', item.CategoryLink, item.CategoryName); Thing is, when I click a tab, and before it is done loading I click another tab, the previous request is aborted and never called again when I click that first one again! this is very bad, because it obviously didn't fetch the request, so what gives? I tried bypassing this by setting: .tabs({ cache: false }) but this is a bad thing to do, because I don't want to have a request each time again... it should be cachced if response was sent. using jquery-ui 1.8.1

  • Do you take the pain of learning it or use an out of the box solution?

    - by Mantorok
    Hi all What I'm getting at here is being presented with a control or framework that does 95% of what you want but has its shortcomings when opposed to learning how to do it yourself. To give a good example (ASP.Net) UpdatePanel vs DIY JS/JSON. The UpdatePanel gives you AJAX instantly without doing anything additional, however I've come to learn that its shortcomings are mainly that it's a bit of a hack and performs badly on busy pages and I've found myself having to scrap UpdatePanels in favour of rolling my own JS, and I've now made it a habit to fully investigate any shortcomings in out-of-the-box solutions, as I've been stung by this experience. So I guess what I'm asking is: Is it better to find out how to DIY or is it considered a better approach to try the available solution and risk going a full circle? Obviously I've only targetted a single control, but it is a very attractive control to people learning AJAX - I'm sure there are others out there. Sorry if dupliate. Thanks

  • Addslashes, mysql_real_escape always adding two slashes?

    - by Zach
    I'm having an issue with inserting JSON into a database, my intention is to take the variables, json_encode them, remove slashes (from magic_quotes), and then addslashes back in to escape the quotes in {"key":"value"} Unfortunately, strip_slashes on the encoded string isn't doing anything, and outputs this {"content":"<p>This string has it\'s downsides</p>","date":1271352514} I have then tried addslashes, and mysql_real_escape_string, both output "{\\"content\\":\\"<p>This string has it\\\'s downsides</p>\\",\\"date\\":1271352514}" I can't work out why it's adding in two slashes? And I'm tearing my hair out over this, everytime I try to stripslashes it leaves one in, and adding slashes adds two. Any help would be hugely appreciated!

  • When is a Google Maps API key required?

    - by Thomas
    Recently Google changed it's policy on the use API keys. You're now supposed to no longer need an API key to place Google Maps on your website. And this worked perfectly. But now I have this map (without API key) running on my localhost, which works fine. But as soon as I place it online, I get a popup saying that I need another API key. And on another page on that website, Google Maps does work. Could it maybe have something to do with that the map that doesn't work have a lot (30+) of markers on it? Actually using an API key wouldn't be a very nice solution to me, as this is part of a Wordpress plugin used on many websites.

  • Cannot see response body in ie8 when response http status code is set to some error code(422)

    - by Deewendra Shrestha
    I am making a requset to a web service that sends custom error with proper HTTP header when I notice some validation error, this works fine in chrome and mozilla as things always do and then it broke in ie8 as it always does! After checking the network activity, I see that ie8 is not able to get response body when HTTP code is other that 200(or at-least it seems so). In groovy I am returning error like : render(status: 422, contentType: 'TEXT', text: ((errors as JSON) as String)) Is there a way I could somehow get ie8 to read in the response body, or as an alternative I might be able to set response header but before trying that I was wondering if you guys have already seen this issue and know a solution to it. Thanks, Dee

  • Handling Exceptions that happen in a asp.net MVC Controller Constructor

    - by Jason
    What's the best way to handle exceptions that happen from within a controller's constructor? All I can think of to do is use Application_OnError() or put a try/catch in my ControllerFactory. Neither of these solutions seem ideal. Application_OnError is to broad - I have some non-mvc content in the site that has its own error handling. Using a try/catch block seems kinda hacky. If I'm serving different content type -html/text/json/rss.... I would like to be able to handle the exception from within the action method instead of having to write all kinds of conditions to determine what kind of error message to serve. Am I missing something here, or has anyone else dealt with this?

  • GWT and a jaxb objects

    - by arinte
    I am trying to use GWT to build objects on the client side that would be sent to a web service elsewhere. These objects are generate through JAX-WS which I am pretty sure uses jaxb to build objects from the xsds that are in the wsdl. Anyhow, GWT was supposed to be able to support this by ignoring annotations or whatever, but it isn't working for me. Here is one of the errors that I am getting: Line 4: The import javax.xml.bind cannot be resolve I am using GWT 2 and the Google plugin for Eclipse.

  • Is C# WebAPI worth it? Can I use standart MVC4 to create my API?

    - by Steve
    I need to build a massive API and I'm trying out WebAPI instead of default MVC4 projects and it seems that it just makes things more difficult. Can have only 4 methods in controller Get, Post, Put, Delete, if I want more I need to modify route for that particular method FluentValidation won't work with WebAPI so I need to use DataAnnotations which I really don't want to. Can't use dynamic return data-types My question is: Would it really be that bad if I would use MVC4 project and use default ActionResults that return Json? What are real advantages of using WebAPI, why did they even made them in the first place if you can easily convert your project to API?
