  • Facebook Connect Dialog Popup

    - by James
    Hello, When using the "Connect" facebook connect button, when I click it, it opens up a new popup window outside of the current window.

I've attached a sample site to see if you can make anything out of it. http://bit.ly/c9Emi Thank you.

  • Ajax long polling (comet) + php on lighttpd v1.4.22 multiple instances problem.

    - by fibonacci
    Hi, I am new to this site, so I really hope I will provide all the necessary information regarding my question. I've been trying to create a "new message arrived notification" using long polling. Currently I am initiating the polling request by window.onLoad event of each page in my site. On the server side I have an infinite loop: while(1){ if(NewMessageArrived($current_user))break; sleep(10); } echo $newMessageCount; On the client side I have the following (simplified) ajax functions: poll_new_messages(){ xmlhttp=GetXmlHttpObject(); //... xmlhttp.onreadystatechange=got_new_message_count; //... xmlhttp.send(); } got_new_message_count(){ if (xmlhttp.readyState==4){ updateMessageCount(xmlhttp.responseText); //... poll_new_messages(); } } The problem is that with each page load, the above loop starts again. The result is multiple infinite loops for each user that eventually make my server hang. *The NewMessageArived() function queries MySQL DB for new unread messages. *At the beginning of the php script I run start_session() in order to obtain the $current_user value. I am currently the only user of this site so it is easy for me to debug this behavior by writing time() to a file inside this loop. What I see is that the file is being written more often than once in 10 seconds, but it starts only when I go from page to page. Please let me know if any additional information might help. Thank you.

  • disallow selection inside an input element

    - by mkoryak
    I am looking to do the following Disallow text selection inside of an input element Do not show the cursor carrot inside of an input i cannot simply blur the input on click, focus must remain in the input. There is probably a way to do this in just IE, i would of course rather have a cross browser solution but ill settle for IE (or FF) only solution. Here is a demo page where you can see why i might need this functionality: http://programmingdrunk.com/current-projects/dropdownReplacement/ if you click on the dropdowns in the first row on page, you will see the carrot inside the dropdown which looks funny. (this wont happen in chrome, but will in FF or IE)

  • How do I convert an AMD module from a singleton to an instance?

    - by Jamie Ide
    I'm trying to convert a working Durandal view model module from a singleton to an instance. The original working version followed this pattern: define(['knockout'], function(ko) { var vm = { activate: activate, companyId: null; company: ko.observable({}) }; return vm; function activate(companyId) { vm.companyId = companyId; //get company data then vm.company(data); } } The new version exports a function so that I get a new instance on every request... define(['knockout'], function(ko) { var vm = function() { activate = activate; companyId = null; company = ko.observable({}); }; return vm; function activate(companyId) { vm.companyId = companyId; //get company data then vm.company(data); } } The error I'm getting is "object function () [...function signature...] has no method company on the line vm.company(data);. What am I doing wrong? Why can I set the property but can't access the knockout observable? How should I refactor the original code so that I get a new instance on every request? My efforts to simplify the code for this question hid the actual problem. My real code was using Q promises and calling two methods with Q.All. Since Q is in the global namespace, it couldn't resolve my viewmodel after converting to a function. Passing the view model to the methods called by Q resolved the problem.

  • Recommendations on Triming Large Amounts of Text from a DOM Object

    - by aronchick
    I'm doing some in browser editing, and I have some content that's on the order of around 20k characters long in a <pre>. So it looks something like: <pre> Text 1 Text 2 Text 3 Text 4 [...] Text 20,000 </pre> I'd like to use jquery to trim it down when someone hits a button to chop, but I'm having trouble doing it without overloading the browser. Assume I know that the character numbers are at 16,510 - 17,888, and what I'd like to do is trim it. I was using: jQuery('#textsection').html(jQuery('textarea').html().substr(range.start)); But browsers seem to enjoy crashing when I do this. Alternatives?

  • Problem with Railscast #197 - Nested Model Form Part 2

    - by sscirrus
    I'm trying to implement Ryan's Railscast #197 in a system with Questions, Answers, and (multiple choice) Options. http://railscasts.com/episodes/197-nested-model-form-part-2. I have successfully implemented the nesting among these forms/partials. The simpler 'check box' way to delete records works properly. The problem occurs when I try to add/delete records. I have copied the code exactly as it appears in his Railscast: #new.html.erb <%= javascript_include_tag :defaults, :cache => true %> <% f.fields_for :in_options do |builder| %> <%= render "option_fields", :f => builder %> <% end %> #_option_fields.html.erb partial <%= f.hidden_field :_destroy %> <%= link_to_function "remove", "remove_fields(this)" %> #application_helper.rb (exact same as #197) def link_to_remove_fields(name, f) f.hidden_field(:_destroy) + link_to_function(name, "remove_fields(this)") end def link_to_add_fields(name, f, association) new_object = f.object.class.reflect_on_association(association).klass.new fields = f.fields_for(association, new_object, :child_index => "new_#{association}") do |builder| render(association.to_s.singularize + "_fields", :f => builder) end link_to_function(name, h("add_fields(this, \"#{association}\", \"#{escape_javascript(fields)}\")")) end #application.js (exact same as #197. I have an Event.addbehavior below this code.) function remove_fields(link) { $(link).previous("input[type=hidden]").value = "1"; $(link).up(".fields").hide(); } function add_fields(link, association, content) { var new_id = new Date().getTime(); var regexp = new RegExp("new_" + association, "g") $(link).up().insert({ before: content.replace(regexp, new_id) }); } 2 problems: When I click on the 'remove' link it doesn't remove - it just shifts the page up or down. When I include link_to_add_fields "Add Answer", f, :answers, I get undefined method `klass' for nil:NilClass. Thanks everyone.

  • jQuery tooltip: Trouble with remove()

    - by Rosarch
    I'm using a jQuery tooltip plugin. I have HTML like this: <li class="term ui-droppable"> <strong>Fall 2011</strong> <li class="course ui-draggable">Biological Statistics I<a class="remove-course-button" href="">[X]</a></li> <div class="term-meta-data"> <p class="total-credits too-few-credits">Total credits: 3</p> <p class="median-GPA low-GPA">Median Historical GPA: 2.00</p> </div> </li> I want to remove the .course element. So, I attach a click handler to the <a>: function _addDeleteButton(course, term) { var delete_button = $('<a href="" class="remove-course-button" title="Remove this course">[X]</a>'); course.append(delete_button); $(delete_button).click(function() { course.remove(); return false; }).tooltip(); } This all works fine, in terms of attaching the click handler. However, when course.remove() is called, Firebug reports an error in tooltip.js: Line 282 tsettings is null if ((!IE || !$.fn.bgiframe) && tsettings.fade) { What am I doing wrong? If the link has a tooltip attached, do I need to remove it specially? UPDATE: Removing .tooltip() solve the problem. I'd like to keep it in, but that makes me suspect that my use of .tooltip() is incorrect here.

  • Passing variables to callback functions

    - by mickyjtwin
    I am trying to write a jQuery plugin, that can be applied to a selector. Within this plugin, there are multiple calls to webservices, where callback methods are required. The problem I am having is maintaining the current context item in the each loop of the selector. (function($){ $.fn.myMethod = function(){ return this.each(function(){ var c = $(this); $.api.methodToCall("", CallbackFunction); }); }; function CallbackFunction(data, result){ // do stuff based on c } })(jQuery); Normally, you would provide the callback function straight away, which allows me to access c, however within the callback function, there potentially is another api call, so it would start to get messy. Is there any way to do this?

  • js regex replace multiple words

    - by Raghav
    I need to replace ${conferance name} with ABC, ${conference day} with Monday in the following sentence. Could some one help me with the regex. var text = "<td>${conference name}</td><td>${conference day}</td>" var list = ["${conferance name}", "${conference day}" ] for (var j = 1; j < list.length; j++) { //Extracting the col name var colName = list[j].split("${"); colName = colName.split("}")[0]; //Replacing the col name text = text.replace(new RegExp('\\$\\{' + colName + '\\}', 'g'), "ABC"); } The above code repalces fine if i have ${conference_name}, but it fails when i have a space in between. The list is a dynamic array. And the Replace statements are also dynamic. I just simulated them as objects here for fitting them in the Regex Statement. Thanks in Advance.

  • Calling methods within same Javwscript class [Prototype]

    - by eldeejay
    I've created a class in Javscript using the prototype Class.Create complete with the initialize function and a few other functions. However, in one of my functions I want to reference another function in the same class, but cannot seem to get the syntax correct. e.g. var sampleClass = Class.create({ initialize: function(){ //do the init work here }, functionA: function(){ //do some more stuff here } functionB: function(){ //Do some stuff functionA() } } I've tried calling functionA() , this.functionA() but nothing works I just get errors. I know how to call the functions externally when the class has been instantiated, but not reference a function from within the class itself. Thanks

  • Slow page unload in IE

    - by ForYourOwnGood
    I am developing a site which creates many table rows dynamically. The total amount of rows right now is 187. Everything works fine when creating the rows, but in IE when I leave the page, there is a large amount of lag. I do not know if this is some how related to the heavy DOM manipulation I am doing in the page? I do not create any function closures when building the dynamic content's event handlers so I do not believe this problem is related to memory leaks. Any insight is much appreciated.

  • Having issues when trying to insert an ajax response which is an html block into an element on IE 8

    - by user340812
    Hello Everyone just like my title states, I am having issues with IE8 and innerHTML. For whatever reason, when I make an ajax call which returns an html block and try to insert it into an element using innerHTML, the browser gives me an error "Unknown Error Code: 0". The interesting part of this is that, if the message response does not have html element, innerHTML works. My code is like so: setTimeout(function() { element.innerHTML = context.response.message; }, 1000).bind(context) WORKS: context.response.message = 'String'; Does not WORK: context.response.message = '<p>String</p>';
