• IE is not loading all images

  - by newbie

  I have jQuery code that loads images with jQuery load method. It works perfectly in all other browsers, except in IE. I have about 10 images, but IE only loads few of those images and then stops loading. What could be causing this? $(".image-container").each(function() { ... some code here ... var img = $("img", this); $(img).load(function () { ... some code here ... }); });

• Updating div after full page refresh following AJAX request

  - by TonE

  Hi, I have an AJAX controller action which returns JSON. The returned JSON is handled via jQuery and contains a message displayed in an update div. The JSON also contains a flag which indicates a change in state. If this is true the entire page needs to be reloaded from a different url. This is currently performed in the jQuery using window.location.replace(url). In the situation where a full page refresh occurs, I still want to display the message from the JSON in the update div, but after the page has fully reloaded. How can I ensure the div is updated with the message after the window.location.replace call and the page has been completely reloaded? Thanks. (I realise AJAX is not intended for full page refreshes but I can't think of a simple way of avoiding it in this scenario. Normal behaviour here is updating the div with a status message.)

  I want to add a very simple bit of code to a jsfiddle, but when ever I do it breaks everything else.

• Get original element using .on

  - by RGraham

  When using jQuery's event delegation, is there a way to retrieve the element on which .on was called, as well as the element on which the event was called? jQuery: $(".item").on("click","a",function() { var link = $(this); // a tag var itemDiv = // what? }); HTML: <div class="item"> <a href="#">Link</a> <a href="#">Link</a> <a href="#">Link</a> <a href="#">Link</a> </div>

• Rails - Posting a Boolean (true or False) and updating the DB in the controller

  - by AnApprentice

  Hello, in my Rails 3 App, I'm posting with jQuery the following: http://0.0.0.0:3000/topics/read_updater?&topic_id=101&read=true In my controller: def read_updater current_user.topics.where(:topic_id => params[:topic_id]).update_all(:read => params[:read]) render :json => {:status => 'success' } end params[:conversation_id] works great, but params[:read] is inserting empty values in the DB, even though jQuery is posting either a true or false. Ideas? I want rails to update the DB with either true or false. Thanks

• WCF - call same service from client and server side

  - by Steve

  I have a simple WCF service that I call server side from code behind via a service reference. It's used for validation and works and was automatically setup by Visual Studio and is using SOAP I think because the binding is wsHttpBinding. I want to use the same WCF service, but call it client side from jQuery using ajax(). I'm trying to implement it by way of these instructions. But if I make the changes to get the client side call working, I have to add the decoration below which I think will break what works on the server side and also change the system.serviceModel section in web.config. [WebInvoke(Method = "POST", BodyStyle = WebMessageBodyStyle.Wrapped, ResponseFormat = WebMessageFormat.Json, RequestFormat= WebMessageFormat.Json) ] How do I have a WCF service that can be called both from the server-side and client side (jQuery/ajax)?

• Sinatra, JavaScript Cross-Domain Requests JSON

  - by pex

  I run a REST-API build on top of Sinatra. Now I want to write a jQuery Script that fetches data from the API. Sinatra is told to response with JSON before do content_type :json end A simple Route looks like get '/posts' do Post.find.to_json end My jQuery script is a simple ajax-call $.ajax({ type: 'get', url: 'http://api.com/posts', dataType: 'json', success: function(data) { // do something } }) Actually everything works fine as long as both runs on the same IP, API and requesting JS. I already tried to play around with JSONP for Rack without any positive results, though. Probably I just need a hint how to proceed.

• What would you use for auto completion in Rails app?

  - by Andrei

  I want to use auto-completion in a number of fields (5-7) in my forms. There is a screencast on auto-completion with Prototype library by Ryan Bates ( http://railscasts.com/episodes/102-auto-complete-association). On the other hand, I have noticed that quite many guys suggest jQuery for this task ( http://jquery.bassistance.de/autocomplete/demo/). And I guess, there was probably some development last year(s), so I ask you - what would you use nowadays to auto-complete your form fields and why? BTW, I still have an open question on auto completion for HABTM association: http://stackoverflow.com/questions/1510935/how-to-do-habtm-management-with-auto-completion-in-rails

• How do I change the style of an input box in IE7 on focus?

  - by Cen

  I know IE7 has issues... I've read posts here and on Google telling me I need to set the style by hand onfocus() and onblur(). However, everything I try isn't working! Here is my jQuery $(document).ready(function(){ if (jQuery.browser.msie === true) { $("input.date-picker").each(function(i) { var $foo= $(this); $foo.bind('onfocus onblur', function() { $(this).toggleClass('smalltxt-active'); }); }); }//end if }); The a corresponding box <input name="ctl00$SelectionContent$Selections1$txtDestinationDate" type="text" id="ctl00_SelectionContent_Selections1_txtDestinationDate" class="date-picker" style="width:80px;" /> I have already confirmed that my code is detecting MSIE. That I am getting a count of 2 input.date-picker objects. Any ideas? Thanks in advance,

• Bootstrap-Switch options don't take effect

  - by Linda Keating

  I'm using Bootstrap-Switch and the documentation says that options can be passed as an object on initialization. enter link description here And here is a list of options: enter link description here So my code looks like this: var options = { onText: "Yes", onColor: 'primary', offColor: 'danger', offText: "No", animate: true, }; $("[name='radioGroup1']").bootstrapSwitch(options); And it all switch works fine, but none of the defaults are overwritten by the options. Anybody got any examples of how this might work? Thanks

• How could I implement a fuzzy time date replacer using Knockout?

  - by rball

  I'd like to implement what this plugin does using jQuery: https://github.com/rmm5t/jquery-timeago A short description of that plugin: This will turn all abbr elements with a class of timeago and an ISO 8601 timestamp in the title (conforming to the datetime design pattern microformat): <abbr class="timeago" title="2011-12-17T09:24:17Z">December 17, 2011</abbr> Into something like this: <abbr class="timeago" title="December 17, 2011">about 1 day ago</abbr> Except using knockout my markup looks like this: <abbr data-bind="attr: { title: Posted }" class="timeago"></abbr> I think something isn't synced up because nothing is happening even if I put the call to timeago within the viewmodel itself. I'm guessing I need a subscriber that's attached to the observable "Posted" but I'm not sure how to set that up.

• Need a Javascript Expert, IE slow script

  - by Aaron Carlino

  I have a jQuery plugin running on my site that is executing very, very slowly in IE7/8 to the point that it throws a slow script warning to the user. It doesn't happen in any other browser, and I can't figure out what might be going on. If you go to this page: http://dev.xeetic.org/projects You'll see that there are 16 results on each page, and each one has a "flip" behavior attached, using the jQuery plugin "quickflip." Attaching this behavior is very slow in IE. If I reduce the result set to 8 or 4 per page, it's faster, but still very bogged down. I have contacted the author of the script with no success. I am willing to pay for a solution, if I'm allowed to offer such a thing on this site. Very desperate. Please help!

• Change the value of an existing onclick function

  - by Mark Peach

  I have a page that is pulling in via an iframe a page of html content from a pre-existing content management system, whose content I can not directly change. I want to use jquery to alter some of the links and button locations dynamically. For links within the page I was able to change the href attr values of <a href="/content.asp">more</a> from content.asp to content2.asp using $("a[href^='/content.asp']") .each(function() { this.href = this.href.replace("content.asp", "content2.asp"); }); But the page pulled in also has form buttons that contains javascript onclick functions e.g. <INPUT type="button" value="Add to basket" onClick="document.location='/shopping-basket.asp?mode=add&id_Product=1076';"> I basically want to use jquery to select any such buttons and change the shopping-basket.asp to shopping-basket2.asp How can I select these buttons/onclick functions and change the location string?

  - by kranthi

  hi, I am using jquery ajax method on my aspx page,which will invoke the webmethod in the code behind.Currently the webmethod takes a couple of parameters like firstname,lastname,address etc which I am passing from jquery ajax method using data:JSON.stringify({fname:firstname,lname:lastname,city:city}) now my requirement has been changed such that,the number and type of parameters that are going to be passed is not fixed for ex.parameter combination can be something like fname,city or fname,city or city,lname or fname,lname,city or something else.So the webmethod should be such that it should accept any number parameters.I thought of using arrays to do so, as described here.

• Rewriting .each() loop as for loop to optimize, how to replicate $(this).attr()

  - by John B

  I running into some performance issues with a jquery script i wrote when running in ie so I'm going through it trying to optimize any way possible. Apparently using for loops is way faster than using the jQuery .each method. This has led me to a question regarding the equivalent of $(this) inside a for loop. I'm simplifying what I'm doing in my loop down to just using an attr() function as it gets across my main underlying question. Im doing this with each(simplified) var existing = $('#existing'); existing.each(function(){ console.log($(this).attr('id')); }); And I've tried rewriting it as a for loop as such: var existing = $('#existing'); for(var i = 0;i < existing.length;i++) { console.log(existing[i].attr('id')); } Its throwing an error saying: Uncaught TypeError: Object #<HTMLDivElement> has no method 'attr' Thanks.

• Implementing hoverIntent for Drop Down Menu (coming from click_event)

  - by stormeTrooper

  I've just recently started programming, I was hoping for some help. I have a drop down menu that was originally activated by click_event, however I want to now implement hoverIntent in order to make the menu drop. The issue I am having now is being able to use the menu, because whenever I invoke the menu now, once I leave the area that activates the menu, the menu closes. If you could explain to me like I'm five, I'd appreciate it, thanks :) The code I am using as follows: JavaScript: function setupUserConfigMenu() { $('.user_profile_btn').hoverIntent( function (event) { $('#user_settings_dropdown').animate({height:['toggle', 'swing'] }, 225); }, function (event) { $('#user_settings_dropdown').animate({height:['toggle', 'swing'] }, 225); }) } HTML: <li> <a href="<%= "#" %>" class="user_profile_btn" title="Your profile page"><%= truncate(current_user.full_name || current_user.name, :length => 28) %> <div class="arrow_down"></div></a> <ul id="user_settings_dropdown"> <li> <a href="<%= current_user.get_url(true) %>"> <%= image_tag current_user.get_thumb_url, :size => "30x30" %> <div> <%= truncate(current_user.full_name || current_user.name, :length => 40) %> <br> View profile </div> </a> </li> <div class="grey_line"></div> <li class="settings_list_item"> <%= link_to "Settings", edit_user_registration_path %> </li> <li class="settings_list_item"> <%= link_to "About", "/about" %> </li> <li class="settings_list_item"> <%= link_to "Logout", destroy_user_session_path, :method => :delete %> </li> </ul> </li>

• Z-Index problems with IE6 and html <select> element

  - by rsturim

  I have a <div> that opens up on a jquery hover event (display goes from hidden to block). Sometime it's opens up over some form elements. And of course it works fine in all browsers except IE6. <select> boxes bleed through as if there z-index is higher than the <div> tag. I've tried setting the <div> tag with a higher z-index, but it still gets ignored by IE6. I'm hoping to implement any fix -- jquery or css, I really don't care at this point. Any ideas?

• show the list of usernames inside a div

  - by Mr_Green

  I am new to jQuery. In my project, I created one Class User in which the code is as shown below: static ConcurrentDictionary<string, User> _users = new ConcurrentDictionary<string, User>(); // // some function to add values to _users list // public List<User> GetConnectedUsers() { return _users.Values.ToList(); } I want to show this list of values in div #showUsernames. How to do this by using jQuery? I tried the below which is not showing anything /*display your contacts*/ $('#showUsernames').append(function(){ chat.server.getConnectedUsers(); }); where chat.server(signalr) calls the server-side code(Chat class).. I think the solution has nothing to do with signalr. If the above description is not enough then you can go through my code here
