  • How to add values to a JSON object?

    - by Damiano
    Hello everybody, I have created an array with: var msg = new Array(); then, I have a function that add values to this array, this function is: function add(time, user, text){ var message = [time, user, text]; if (msg.length >= 50) msg.shift(); msg.push(message); } As you can see, if the array has 50 or more elements I remove the first with .shift(). Then I add an array as element. Ok, the code works perfectly, but now I have to loop the msg array to create a JSON obj. The JSON object should has this format: var obj = [ {'time' : time, 'user' : user, 'text' : text}, {'time' : time, 'user' : user, 'text' : text}, {'time' : time, 'user' : user, 'text' : text} ] I mean...i have to loop msg array and then store all the values inside the JSON object. I do not know how to "concatenate" the element of the array inside json obj. Could you help me? Thank you very much in advance!

  • Loading/Displaying large amount of data on webpage.

    - by jb
    I have a webpage which contains a table for displaying a large amount of data (on average from 2,000 to 10,000 rows). This page takes a long time to load/render. Which is understandable. The problem is, while the page is loading the PCs memory usage skyrockets (500mb on my test system is in use by iexplorer) and the whole PC grinds to a halt until it has finished, which can take a minute or two. IE hangs until it is complete, switching to another running program is the same. I need to fix this - and ideally i want to accomplish 2 things: 1) Load individual parts of the page seperately. So the page can render initially without the large data table. A loading div will be placed there until it is ready. 2) Dont use up so much memory or local resources while rendering - so at least they can use a different tab/application at the same time. How would I go about doing both or either of these? I'm an applications programmer by trade so i am still a little fizzy on the things I can do in a web environment. Cheers all.

  • Change a select list display value upon selecting description

    - by eli
    Hello, I would like a select list that does the following: When the select list is open, display the list of descriptions. When the user selects an item, the select list will close an only the value will be displayed. The reason for this is to conserve space as the values will be much shorter. I'm hoping that there's an answer in jQuery. Thanks.

  • Defining a recursive function in a Prototype class?

    - by btl
    I'm trying to create an image rotator class that cycles through an arbitrary number of images in an unordered list. Is it possible to define a recursive function within a class declaration? E.g: var Rotator = Class.create() { initialize: function() { do something... this.rotate(); } rotate: function() { do something... this.rotate() } }

  • How to remove the upper right close button

    - by tahdhaze09
    I need to kill the close 'x' button at the top of a jQuery UI modal dialog box. I have a modal that opens with an OK button that redirects to the site. The site behind the modal is in an iframe. When the user agrees to the statement in the dialog box and clicks the 'OK' button, it redirects to the site that is outside the iframe. If the user clicks on the 'x', it goes to the iframe site, which I do not want to have happen. I need the modal to work as a one-way to the site it goes to. It basically forces the user to accept the user agreement. I would post code, but its an intranet site. Thanks everyone for your help! EDIT: This site is a government intranet portal, not a commercial site. So the goal is NOT to trap a user into the site, but rather to let the user know that the use of this site is restricted and to make sure you understand and accept the user agreement or you cannot use the site.

  • Destroying a record via RJS TemplateError (Called ID for nil...)

    - by bgadoci
    I am trying to destroy a record in my table via RJS and having some trouble. I have successfully implemented this before so can't quite understand what is not working here. Here is the setup: I am trying to allow a user of my app to select an answer from another user as the 'winning' answer to their question. Much like StackOverflow does. I am calling this selected answer 'winner'. class Winner < ActiveRecord::Base belongs_to :site belongs_to :user belongs_to :question validates_uniqueness_of :user_id, :scope => [:question_id] end I'll spare you the reverse has_many associations but I believe they are correct (I am using has_many with the validation as I might want to allow for multiple later). Also, think of site like an answer to the question. My link calling the destroy action of the WinnersController is located in the /views/winners/_winner.html.erb and has the following code: <% div_for winner do %> Selected <br/> <%=link_to_remote "Destroy", :url => winner, :method => :delete %> <% end %> This partial is being called by another partial `/views/sites/_site.html.erb and is located in this code block: <% if site.winners.blank? %> <% remote_form_for [site, Winner.new] do |f| %> <%= f.hidden_field :question_id, :value => @question.id %> <%= f.hidden_field :winner, :value => "1" %> <%= submit_tag "Select This Answer" %> Make sure you unselect any previously selected answers. <% end %> <% else %> <div id="winner_<%= site.id %>" class="votes"> <%= render :partial => site.winners%> </div> <% end %> <div id="winner_<%= site.id %>" class="votes"> </div> And the /views/sites/_site.html.erb partial is being called in the /views/questions/show.html.erb file. My WinnersController#destroy action is the following: def destroy @winner = Winner.find(params[:id]) @winner.destroy respond_to do |format| format.html { redirect_to Question.find(params[:post_id]) } format.js end end And my /views/winners/destroy.js.rjs code is the following: page[dom_id(@winner)].visual_effect :fade I am getting the following error and not really sure where I am going wrong: Processing WinnersController#destroy (for 127.0.0.1 at 2010-05-30 16:05:48) [DELETE] Parameters: {"authenticity_token"=>"nn1Wwr2PZiS2jLgCZQDLidkntwbGzayEoHWwR087AfE=", "id"=>"24", "_"=>""} Rendering winners/destroy ActionView::TemplateError (Called id for nil, which would mistakenly be 4 -- if you really wanted the id of nil, use object_id) on line #1 of app/views/winners/destroy.js.rjs: 1: page[dom_id(@winner)].visual_effect :fade app/views/winners/destroy.js.rjs:1:in `_run_rjs_app47views47winners47destroy46js46rjs' app/views/winners/destroy.js.rjs:1:in `_run_rjs_app47views47winners47destroy46js46rjs' Rendered rescues/_trace (137.1ms) Rendered rescues/_request_and_response (0.3ms) Rendering rescues/layout (internal_server_error)

    - by aldux
    How can I temporarily disable the onclick event listener, (jQuery preferred), after the event has been fired? Example: After the user clicks on the button and fires this function below, I want to disabled the onclick listener, therefore not firing the same command to my django view. $(".btnRemove").click(function(){ $(this).attr("src", "/url/to/ajax-loader.gif"); $.ajax({ type: "GET", url: "/url/to/django/view/to/remove/item/" + this.id, dataType: "json", success: function(returned_data){ $.each(returned_data, function(i, item){ // do stuff }); } }); Thanks a lot, Aldo

  • Display/Hide part of a list

    - by superexsl
    Hi I have an (unordered)list (generated by a repeater) of items. However, I'd like to show the first three items, and have the rest hidden by the main content div. When a button is pressed, I would like the list's div to expand, pushing the main content div down and showing the rest of the list. I was thinking of using slideDown(), but that closes the entire div ( and I would like to show the first 3 items of the list). What would be the best way to achieve an effect like this? Is there a plugin that can easily show X items of a list and the display the rest upon request? Thanks

  • Special Characters in JS, how to use "/" character

    - by user1461222
    I've vbulletin 4.2.0 i added an special button to it's editor with this article; http://www.vbulletinguru.com/2012/add-a-new-toolbar-button-to-ckeditor-tutorial/ The thing i want to do is add an syntax highlighter code with this button. When i use below code it's working fine; CKEDITOR.plugins.add( 'YourPluginName', { init: function( editor ) { editor.addCommand( 'SayHello', { exec : function( editor ) { editor.insertHtml( "Hello from my plugin" ); } }); editor.ui.addButton( 'YourPluginName', { label: 'My Button Tooltip', command: 'SayHello', icon: this.path + 'YourPluginImage.png' } ); } } ); so i changed this code to this, because i wannt to add specific text like below; CKEDITOR.plugins.add( 'DKODU', { init: function( editor ) { editor.addCommand( 'SayHello', { exec : function( editor ) { editor.insertHtml( '[kod=delphi][/kod]' ); } }); editor.ui.addButton( 'DKODU', { label: 'My Button Tooltip', command: 'SayHello', icon: this.path + 'star.png' } ); } } ); after update the code when i press the button nothings happen, i checked with google and this site but i couldn't figure it out i think i made mistake with some special characters but i couldn't find what's the problem. If i made some mistakes when i publish this question forgive me and also forgive me for my bad english, thanks.

  • IE 8 specifying background-color changes element behavior

    - by Mateo
    I have an absolutely positioned div on which I am trying to trigger mouseenter and mouseleave events. In IE8/7 with the background-color of the div left unspecified (so that it defaults to transparent), the mouseenter/leave events are not firing when the cursor crosses the div's boundary, only somewhere in the middle of the div and when the cursor is over any text within the div. When I attempt to debug the problem by adding a background color to the div (e.g. background-color: green), the problem magically goes away. The div's box model is honored perfectly and mouseenter/leave fire as when expected. It's only when the div's background color is left unspecified (or even explicitly set to transparent) that it doesn't behave correctly. Any ideas? Googling for this IE bug/quirk is coming up with nothing.

  • Assign different colors to individual array elements

    - by rk.
    Say I have the array, arr1. I want to print this array (i.e. just display the numbers) but, I want to color the numbers based on their values. If arr1[i]<15, green, if arr1[i]20, red, else orange. Something to this effect. var arr1 = [ 5,10,13,19,21,25,22,18,15,13,11,12,15,20,18,17,16,18,23,25,25,22,18,15,13,11,12,15,20,18]; Here is what I tried doing: for(var i=0; i<arr1.length;i++){ if(arr1[i]<15){ var temp = $(this).css("color","green"); $this.text(temp); } else if(arr1[i]>20){ var temp = $(this).css("color","red"); $this.text(temp); } else { var temp = $(this).css("color","orange"); $this.text(temp); } } I tried changing the css property of individual elements and them adding them to the div, but it did not work for me. Can someone suggest how should I go about doing this?

  • Is there a sexier way to write this jQuery selector?

    - by Bears will eat you
    I want to select all the children of the body element before element with id foo (which is a child of body). Since it doesn't look like there are :before() or :after() selectors, I've got it working like this: $('body > :first').nextUntil('#foo').andSelf(); but it seems kludgy. Could this be done with fewer function calls, or more efficiently? Maybe something akin to $('body > *:before(#foo)') ?

    Whether JavaSript, C# or C++ main problem i face while reading the code is which function is called by which function. This problem is big when dealing with BIG code. Is there any static code analysis tool/technique/plugins using which a graphical representation of the code can be generated(something like below) so that reading/analyzing code becomes easy? .... --outerFuntion() ---innerFunction() ----innerFunction2() --outerFunction2() ....

  • Print/save full webpage as PDF

    - by Oliver
    I need a method to be able to print/save the current full webpage as a PDF. I know it can be done if I download a PDF printer and print to that; but I need it to be done without the user having to do anything other than click a button in a webpage. I can't do it via PHP as the page is all client side content, so I'm guessing an ActiveX component? Any ideas would be greatly appreciated! Many thanks
