  • Regex with dynamic <textarea>

    - by Oscar Godson
    How can I do this with the JS replace() method: Make \n\n change to <p>$1</p> Change single \n to <br> Then back again. I think I have this part, see the JS at the bottom. Example HTML: <p>Hello</p><p>Wor<br>ld</p> The <textarea> would look like: Hello Wor ld So, how can I achieve this? It's an AJAX form where when you click on this div it changes to a <textarea> and back, and fourth, etc. So, I need to it to go from <p>s and <br>s to \n\n and \n. For the going to <textarea> from HTML I have: $(this).html().replace(/\s?<\/?(p|br\s?\/?)>\s?/g,"\n")

  • JQuery: Get length of JSON reply?

    - by Rosarch
    In a JQuery getJSON call, how can I tell the length of the JSON that's returned? function refreshRoomList() { $.getJSON('API/list_rooms', function (rooms) { if (rooms.length > 0) { $("#existing-room-list").empty(); $("#join-existing-room").text("Join existing room:"); // this shouldn't be here $.each(rooms, function (index, roomName) { var newChild = sprintf('<li><a href="room?key=%s">%s</a></li>', index, roomName); $("#existing-room-list").append(newChild); }); } else { $("#join-existing-room").text("No rooms found."); } }); } For some reason this doesn't work, but if I replace rooms.length > 0 with true, the full list of rooms is printed out.

  • FF extension: saving a value in preferences and retrieving in the js file

    - by encryptor
    I am making an extension which should take a link as the user input only once. Then the entire extension keeps using that link on various functions in the JS file. When the user changes it, the value accessed by the js file also changes accordingly. I am using the following but it does not work for me var pref_manager = Components.classes["@mozilla.org/preferencesservice;1"].getService(Components.interfaces.nsIPrefService) function setInstance(){ if (pref_manager.prefHasUserValue("myvar")) { instance = pref_manager.getString("myvar"); alert(instance); } if(instance == null){ instance = prompt("Please enter webcenter host and port"); // Setting the value pref_manager.setString("myvar", instance); } } instance is the global variable in which i take the user input. The alert (instance) does not show up, which means there is some problem by the way i am saving the pref or extracting it. Can someone please help me with this. I have never worked with preferences before. so even if there are minor problems i might not be able to figure out.

  • How to escape charaters in the title of a marker in a Google Maps?

    - by Anthony
    Say I have this piece of code: var marker = new google.maps.Marker({ position: location, title: 'B&#250;fals', map: map }); This creates a marker as expected but if I hover the mouse over it I don’t see 'Búfals' as I would expect (instead I see the html code). This doesn't make any difference: var marker = new google.maps.Marker({ position: location, title: unescape('B&#250;fals'), map: map }); Any ideas? Thanks.

  • whats faster, more efficient, loading a js file with arrays or populating arrays from tables

    - by Leigh
    I am rebuilding an ecom site where the product data is stored in a multidimensional JS array that gets loaded on page load. This data is constantly being accessed with JS due to the nature of the site, to update prices based on user selections. There are many options that affect final price. From a programming standpoint, a DB table is much easier to maintain and update than are JS arrays, and since I am porting the site over to PHP and MYSQL, I have been considering moving these arrays into tables. So, would it be better to populate an array from the DB on load so that the pricing data is always available to the JS, or stay with hard coded JS files? I considered getting data via ajax as needed, but since this site has to constantly update pricing with user interaction, I have pretty much ruled that out. How would you handle it?

  • Question about A Sketching Website on the IPAD, Dragging and Touching

    - by pfunc
    I've been testing out the new functionality of html5 and js to create a sketching site. I've been looking into this for a possible client that wants their site to be ipad accessible, but also have drawing features on it. So i created a rough experiment where you can drag your mouse across a screen to draw lines. I went to test it on an ipad and realized this doesn't work. Why? because dragging on an ipad is reserved for actually dragging the screen around. Is there something you can do to get around this? I'm sure this could be done if made for an app, but what about just a normal website.

  • Using jQuery to rapidly scroll through a countdown

    - by CaptainAwesomePants
    I have a webpage that displays the number 0, and when the user presses "start", the number should rapidly increasing until it reaches a target number (maybe 10,000 or so) a few seconds later. I'd like the numbers to scroll by as if they're on a slot machine wheel. I've managed to mostly hack something together using the ScrollTo plugin, but it's slow and choppy. It always stops briefly at certain divs along the way. Perhaps I'm using it wrong. Is there a better way to accomplish such an effect?

  • Inereritance of clousure objects and overriding of methods

    - by bobikk
    I need to extend a class, which is encapsulated in a closure. This base class is following: var PageController = (function(){ // private static variable var _current_view; return function(request, new_view) { ... // priveleged public function, which has access to the _current_view this.execute = function() { alert("PageController::execute"); } } })();` Inheritance is realised using the following function: function extend(subClass, superClass){ var F = function(){ }; F.prototype = superClass.prototype; subClass.prototype = new F(); subClass.prototype.constructor = subClass; subClass.superclass = superClass.prototype; StartController.cache = ''; if (superClass.prototype.constructor == Object.prototype.constructor) { superClass.prototype.constructor = superClass; } } I subclass the PageController: var StartController = function(request){ // calling the constructor of the super class StartController.superclass.constructor.call(this, request, 'start-view'); } // extending the objects extend(StartController, PageController); // overriding the PageController::execute StartController.prototype.execute = function() { alert('StartController::execute'); } Inheritance is working. I can call every PageController's method from StartController's instance. However, method overriding doesn't work: var startCont = new StartController(); startCont.execute(); alerts "PageController::execute". How should I override this method?

  • Get the character count of a textarea including newlines

    - by styfle
    I tested this code in Chrome and there seems to be a bug involving the newlines. I am reaching the maxlength before I actually use all the characters. <textarea id="myText" maxlength="200" style="width:70%;height:200px"> Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s...

  • How can one put together multiple arrays into one string?

    - by Noor
    I'm having a hard time describing what I'm looking for. If we pretend that we're pulling an array (I've used the .split to get user input data) where each line represents a link. How can I then add an anchor tagg to that link that I'm pulling? I need to be able to put < a href=" + thearray + "anything< /a. The reason for this is that I'm dynamically creating a list. I think that if I create two variables, one with this part < a href=" one with the closing and then call some sort of function that puts those two and the pulled array in between them until the list is complete. Does this make any sense?

  • How atomic *should* I make an Ajax form?

    - by b. e. hollenbeck
    I have some web forms that I'm bringing over with AJAX, and as I was dealing with the database on the back end, I thought that it might be easier to just handle each input on the form atomically with AJAX, saving the form in 'real time' as the user edits it. The forms are ~20 fields of administrative settings. Would this create massive overhead with the app, cause it to be error-prone, or is this a feasible idea? Of course, contingent operations (like a checkbox that then requires a text entry) would be held until the textbox gained and lost focus. Comments?

  • jQuery AJAX requests with Rails 3

    - by elsurudo
    I'm trying to do a manual jQuery AJAX request the following way: $("#user_plan_id").change(function() { $("#plan_container").load('/plans/' + this.value); }); I have the "rails.js" file included in my header, and a "<%= csrf_meta_tag %". I see from my log that the request IS getting to the server (although without the authenticity token... does rails.js even do this?), but the response is a 302 (Found) rather than 200, and no data actually gets rendered. Any ideas?

  • jQuery: How to fire event when all asynchronous calls return?

    - by Jeremy
    I have a jQuery application that loads data from five asynchronous server calls. I do not want to display any data until all five calls return. (I plan on displaying a Loading message until that happens.) How can I detect when all five calls have returned? I considered having each callback method increment a variable (using jQuery's data() method, perhaps) and then waiting for the value to become 5. (I am not sure yet how I would listen for that event.) I do not think this is a very good solution, however. What would happen if two calls return at the same time? Is there a better way to do this?
