  • jquery vote up down, request for some help

    - by Billa
    I want to make some changes in the following piece of code. The demo of the code can be seen here. http://cyberbuff.noadsfree.com/lab/reddit_votes/ The above example shows calculated number of votes (vote ups - votes down). And when you click on any thumbe, it disappears the thumbs and shows the updated votes. I want to make changes that in begining it shows vote up and vote down separately (which are stored in database separately). and after thumb up or down is pressed, it should not remove the thumbs, but it should show the updated vote up and down separatetly. As shown in the image below. Here are pieces of code: Main page having html/CSS and jquery code. http://pastebin.com/RC6dj6N5 vote processng code: http://pastebin.com/heszKyDc PS. I have tried to change by myself but I could not do. Any help will be much appriciated. Thanks.

  • Rewriting URL in AJAX application

    - by Artem Moskalev
    I am making a simple online application. I have a navigation bar with a few buttons and one "div" into which all the new contents will be loaded dynamically i.e. when I click "About", it will load the page parts into the "div" without reloading the whole page with .load() function. The problem is: what if I need to give a link to the Documents section of my web site, or the user wants to store this kind of link, the url is not rewritten when browsing my site. when the user stores the default link it will always link him to the default "Home" part. How can I rewrite the URL and what is the most correct way to do this?

  • Js Variable Reference Quickie

    - by Nikki
    Hoping someone can clear this up for me. Let's say I have 2 globals: var myarray=[1,3,5,7,9],hold; and then I do this: function setup() { alert (myarray[0]);//shows 1 hold=myarray; alert (hold);//appears to show 'hold' containing all the values of myarray. first number shown is 1 myarray[0]=2; alert (hold);//shows the values of myarray with the updated first entry. first numbe shown is 2 } Am I to take it that 'hold' is simply keeping a reference to myarray, rather than actually taking all the values of?

  • Durandal Google Maps not showing properly

    - by user1891037
    Trying to show Google Maps using the Durandal. I'm now simply working with Durandal HTML Starter Kit so the other modules and all engine works properly. The thing is when I added the Google Map it doesn't fit the div size (the big part of div is just grey). As I understand, the problem is causing because Google Maps added before page is completely loaded. But I can't figure out how can I hook on page load event. Here is the module code: define(['knockout', 'gmaps'], function (ko, gmaps) { return { displayName: 'Google Maps', myMap: ko.observable({ lat: ko.observable(32), lng: ko.observable(10)}), activate: function () { console.log('activate'); ko.bindingHandlers.map = { init: function (element, valueAccessor, allBindingsAccessor, viewModel) { console.log('init'); var mapObj = ko.utils.unwrapObservable(valueAccessor()); var latLng = new gmaps.LatLng( ko.utils.unwrapObservable(mapObj.lat), ko.utils.unwrapObservable(mapObj.lng)); var mapOptions = { center: latLng, zoom: 5, mapTypeId: gmaps.MapTypeId.ROADMAP}; mapObj.googleMap = new gmaps.Map(element, mapOptions); } } }, attached: function() { console.log('attached'); }, compositionComplete: function() { console.log('compositionComplete'); } }; }); And a very simple HTML code: <section> <div id="gmap-canvas" data-bind="map:myMap"></div> </section> I'm loading Google Maps with async plug-in in my shell.js. It works fine. Screenshot with trouble here - http://clip2net.com/s/ibswAa P.S. div size is defined in .CSS file. P.S. I tried to use getElementById approach provided here and it's work great if placed in compositionComplete block. But when I tried to move my bindings to this block nothing happens at all. Thanks!

  • Filtering content (jQuery)

    - by Nimbuz
    HTML: <div class="filter"> <a href="#category-1">category 1</a> <a href="#category-2">category 2</a> </div> <ul class="items"> <li class="category-1">item 1</li> <li class="category-1">item 2</li> <li class="category-2">item 3</li> <li class="category-2">item 4</li> </ul> What I want is for example clicking on 'category 1' link should hide all other category items from the list. I understand jQuery's .filter() selector can be used but I'm not sure how to implement it for my purpose here. Thanks for your help!

  • How do I find the previous/default value of a radio button in JS?

    - by royrules22
    I'm not sure if this is even possible, but I figured I'd ask before clubbing togehter an ugly solution. What I have is a group of radio buttons and I want to trigger a function if the radio button value is changed. For example say there are three buttons X Y and Z with Y default selected. If a user clicks on an unselected button (i.e. X or Z) then the function gets triggered but if he/she clicks on Y (which is already selected) nothing happens. Naturally the best solution would be to fire the function on an onchange event but IE6 doesn't fire onchange until the focus is no longer on the element which is not satisfactory. So is there a way to know what the previous value of the radio button was or at least what its default value is? I could easily create an array of default values and check against that but I'm trying to reduce the overhead. Please no jQuery suggestions ;)

  • What's the best way to set cursor/caret position?

    - by Daniel Bachhuber
    If I'm inserting content into a textarea that TinyMCE has co-opted, what's the best way to set the position of the cursor/caret? I'm using tinyMCE.execCommand("mceInsertRawHTML", false, content); to insert the content, and I'd like set the cursor position to the end of the content. Both document.selection and myField.selectionStart won't work for this, and I feel as though this is going to be supported by TinyMCE (through something I can't find on their forum) or it's going to be a really ugly hack. Later: It gets better; I just figured out that, when you load TinyMCE in WordPress, it loads the entire editor in an embedded iframe. Later (2): I can use document.getElementById('content_ifr').contentDocument.getSelection(); to get the selection as a string, but not a Selection Object that I can use getRangeAt(0) on. Making progress little by little.

  • JQuery Validation Plugin not working when used on page that includes another page via AJAX

    - by droidy
    We have a long page that contains a bunch of different form elements. One part of the form is called remotely via AJAX and is populated in an empty div. This is the part which JQuery Validation plugin is not working correctly on. We have class="required" on the elements on this page, but they do not show up as required. I'm guessing it's because the Validation plugin is looking for class="required" on our main page, and since the content from the AJAX page is put into the empty div behind the scenes, it's not detected the required fields. Any help is greatly appreciated.

  • changing window.location without triggering refresh

    - by jdwyah
    I have an AJAX form that submits GET requests. Because these are all GET requests these should be easily bookmark-able. Preferably I'd make my Ajax request, update the screen and then update window.location.href to be the URL for the new page. Unfortunately this reloads the page. Is there any way I can get around this? Basically I'd like the URL bar to be a permalink bar, but it needs to be able to change to keep up with the state of the page. window.location.hash is no good because that doesn't get sent to the server.

  • Backbone.js - Getting JSON back from url

    - by Brian
    While trying to learn Backbone.js, I've been trying to grab the content of a JSON file using the following code: (function($){ var MyModel = Backbone.Model.extend(); var MyCollection = Backbone.Collection.extend({ model : MyModel, url: '/backbone/data.json', parse: function(response) { console.log(response); return response; } }); var stuff = new MyCollection; console.log(stuff.fetch()); console.log(stuff.toJSON()); })(jQuery) 'stuff.fetch()' returns the entire object (with the data I'm after in responseText), 'stuff.toJSON' returns nothing ([]), but the console in the parse method is returning exactly what I want (the json object of my data). I feel like I'm missing something obvious here, but I just can't seem to figure it out why I can't get the right data out. Could someone point me in the right direction or show me what I'm doing wrong here? Am I using a model for the wrong thing?

  • Incorporation of YUI 3 in rails

    - by lorefnon
    I was wondering if any effort has been made towards integration of YUI3 with rails asset pipeline. By integration, I don't just mean a couple of helpers for including the library but rather a complete integration of YUI module loader. I'll elaborate the idea in detail: Currently, developers developing modules using YUI rely on Ant tasks for concatenating the module components and wrapping them up with some associated metadata and generating target files ( and optionally minifying and running jslint). Also, when fetching the modules, the YUI loader calculates the module dependencies and generates a single file comprising of all the dependencies which havent been included already in the page. I was wondering if the whole functionality could be seamlessly integrated into the Asset pipeline of rails.

  • jQuery UI Draggable 'stop' event called too many times?

    - by Graham
    I have a feeling I'm either misunderstanding the 'stop' event or not doing it right, but it seems to be called several times while the element is bound to is being dragged. makeAllDragable = function () { $(".test-table").draggable({ start: function (event, ui) { $(this).click(); }, stop: function (event, ui) { foo() } }).click(function () { selectTable($(this)); }); } foo = function () { alert("test"); } In this example foo is called about 30 times, shouldn't is just be when I release the draggable? The jQuery docs don't actually say one where or another though.
