  • Named Function Expressions in IE, part 2

    - by Polshgiant
    I asked this question a while back and was happy with the accepted answer. I just now realized, however, that the following technique: var testaroo = 0; (function executeOnLoad() { if (testaroo++ < 5) { setTimeout(executeOnLoad, 25); return; } alert(testaroo); // alerts "6" })(); returns the result I expect. If T.J.Crowder's answer from my first question is correct, then shouldn't this technique not work?

  • cross domain iFrames communication problem

    - by Cyno
    I have a page A containing 2 children iFrames called B and C. A and B are on different domains. On pressing a button in B I would like to change C's URL. Based on the law III of Michael Mahemoff it should work, but in fact it doesn't (js security error). Here is the JS code in B: window.parent.frames['C'].location.href = "http://random.url";

  • Showing popup in the new FB JS SDK

    - by FearUs
    HI, I used to have an Href in my website, when users clicked on it, multi friend selector showed so they can incite their friends to my website. That was done using the following code: FB.ensureInit(function() { var dialog = new FB.UI.FBMLPopupDialog('XXXXXXX', ''); var fbml = 'Multi-Friend-Selector FBML' dialog.setFBMLContent(fbml); dialog.setContentWidth(620); dialog.setContentHeight(570); dialog.show(); }); Now, I'm using the new JS SDK (http://connect.facebook.net/en_US/all.js), but the old methods are not present... How can I do it with the new SDK ??

  • How do I DRY up my CouchDB views?

    - by James A. Rosen
    What can I do to share code among views in CouchDB? Example 1 -- utility methods Jesse Hallett has some good utility methods, including function dot(attr) { return function(obj) { return obj[attr]; } } Array.prototype.map = function(func) { var i, r = [], for (i = 0; i < this.length; i += 1) { r[i] = func(this[i]); } return r; }; ... Where can I put this code so every view can access it? Example 2 -- constants Similarly for constants I use in my application. Where do I put MyApp = { A_CONSTANT = "..."; ANOTHER_CONSTANT = "..."; }; Example 3 -- filter of a filter: What if I want a one view that filters by "is this a rich person?": function(doc) { if (doc.type == 'person' && doc.net_worth > 1000000) { emit(doc.id, doc); } } and another that indexes by last name: function(doc) { if (doc.last_name) { emit(doc.last_name, doc); } } How can I combine them into a "rich people by last name" view? I sort of want the equivalent of the Ruby my_array.select { |x| x.person? }.select { |x| x.net_worth > 1,000,000 }.map { |x| [x.last_name, x] } How can I be DRYer?

  • How can I use jQuery to match a string inside the current URL of the window I am in?

    - by Jannis
    Hi, I have used the excellent gskinner.com/RegExr/ tool to test my string matching regex but I cannot figure out how to implement this into my jQuery file to return true or false. The code I have is as follows: ^(http:)\/\/(.+\.)?(stackoverflow)\. on a url such as http://stackoverflow.com/questions/ask this would match (according to RegExr) http://stackoverflow. So this is great because I want to try matching the current window.location to that string, but the issue I am having is that this jQuery/js script does not work: var url = window.location; if ( url.match( /^(http:)\/\/(.+\.)?(stackoverflow)\./ ) ) { alert('this works'); }; Any ideas on what I am doing wrong here? Thanks for reading. Jannis

  • ExtJS combo setting problem

    - by Hubidubi
    Hi I run into an interesting problem while was using combos in input form. My form contains combos that get data from json stores. It works fine when adding new record, but when the form is opened for editing an existing record, sometimes the id appears as selected not its value (eg: there's 5 instead of "apple"). I think it tries to set the value before it finishes loading the combo. Is there a way to solve this? I put the code down here that creates combos: function dictComboMaker( store, fieldLabel, hiddenName, name, allowBlank, myToolTipp ) { comboo = { xtype : 'combo', id: 'id-'+name, allowBlank: allowBlank, fieldLabel : fieldLabel, forceSelection : true, displayField : 'value', valueField : 'id', editable: false, name: name, hiddenName : hiddenName, minChars : 2, mode: 'remote', triggerAction : 'all', store : store }; function dictJsonMaker(url) { store = new Ext.data.JsonStore({ root : 'results', // 1 fields : [ 'id','value' ], url : url, autoLoad: true}); return store; } var comboKarStore = dictJsonMaker('/service/karok'); var comboKar= dictComboMaker(comboKarStore, 'Kar', 'karid', 'kar', false, ''); // then comboKar is added to the form Hubidubi

  • node.js / socket.io, cookies only working locally

    - by Ben Griffiths
    I'm trying to use cookie based sessions, however it'll only work on the local machine, not over the network. If I remove the session related stuff, it will however work just great over the network... You'll have to forgive the lack of quality code here, I'm just starting out with node/socket etc etc, and finding any clear guides is tough going, so I'm in n00b territory right now. Basically this is so far hacked together from various snippets with about 10% understanding of what I'm actually doing... The error I see in Chrome is: socket.io.js:1632GET http://192.168.0.6:8080/socket.io/1/?t=1334431940273 500 (Internal Server Error) Socket.handshake ------- socket.io.js:1632 Socket.connect ------- socket.io.js:1671 Socket ------- socket.io.js:1530 io.connect ------- socket.io.js:91 (anonymous function) ------- /socket-test/:9 jQuery.extend.ready ------- jquery.js:438 And in the console for the server I see: debug - served static content /socket.io.js debug - authorized warn - handshake error No cookie My server is: var express = require('express') , app = express.createServer() , io = require('socket.io').listen(app) , connect = require('express/node_modules/connect') , parseCookie = connect.utils.parseCookie , RedisStore = require('connect-redis')(express) , sessionStore = new RedisStore(); app.listen(8080, '192.168.0.6'); app.configure(function() { app.use(express.cookieParser()); app.use(express.session( { secret: 'YOURSOOPERSEKRITKEY', store: sessionStore })); }); io.configure(function() { io.set('authorization', function(data, callback) { if(data.headers.cookie) { var cookie = parseCookie(data.headers.cookie); sessionStore.get(cookie['connect.sid'], function(err, session) { if(err || !session) { callback('Error', false); } else { data.session = session; callback(null, true); } }); } else { callback('No cookie', false); } }); }); var users_count = 0; io.sockets.on('connection', function (socket) { console.log('New Connection'); var session = socket.handshake.session; ++users_count; io.sockets.emit('users_count', users_count); socket.on('something', function(data) { io.sockets.emit('doing_something', data['data']); }); socket.on('disconnect', function() { --users_count; io.sockets.emit('users_count', users_count); }); }); My page JS is: jQuery(function($){ var socket = io.connect('http://192.168.0.6', { port: 8080 } ); socket.on('users_count', function(data) { $('#client_count').text(data); }); socket.on('doing_something', function(data) { if(data == '') { window.setTimeout(function() { $('#target').text(data); }, 3000); } else { $('#target').text(data); } }); $('#textbox').keydown(function() { socket.emit('something', { data: 'typing' }); }); $('#textbox').keyup(function() { socket.emit('something', { data: '' }); }); });

  • how to find the height of html content

    - by ganapati hegde
    Hi, I am trying to display 10 html pages as a single document,with 10 chapters. I am using Webkitgtk+ engine to render the HTML pages. I am getting the content of each html files and concatenating all of them to create a single 'char *content' and using webkit_web_view_load_html_string(WebKitWebView *web_view, const gchar *content, const gchar *base_uri); this function to load all the HTML files, as a document. Now i am trying to build a 'table of contents(toc)' for this document, which displays all the chapter names in order. My requirement is, when i click on a particular chapter in toc, the document should scroll to that point. For that i need to know height of each chapter ( height of each html file content). The point to be noted here is, the width of the document can changed and as HTML is reflowable, as width increases height decreases and vice-versa. So each time when height changes i need to find out the current height of each HTML page(or chapter) and hence calculate the distance to be scrolled. How can i find out the height of content of HTML page dynamically ? Thank you for the answer....

  • jQuery Validate - resetForm() Not Behaving as Expected

    - by Kevin C.
    Site in question is http://epraxadev.com/kw/palisade-palms/ "Click here for brochure" and "Learn More about Palisade Palms" both bring up a lightbox with the same HTML form to be filled out...the "learn more..." link also changes some of the HTML in the form (the value for a hidden form field, and the fields required). I'm using Colorbox for the lightbox, and for its onClosed event, I have this to reset the form: onClosed: function() { $('#brochure-form label em').remove(); $('#brochure-form').data('validator').resetForm(); } Now here's the problem: User tries to submit the "brochure" form, but it fails validation. User closes the lightbox. User opens up the "Learn more" lightbox, and tries to submit the form...now, instead of using the correct validation rules (only requiring e-mail and referrer), it requires all fields to be filled out (as is the case with the "Brochure Form") Is there something that I can add to the onClosed function, to clean up all the validation rules? Thanks guys!

  • How can I duplicate the UI functionality of Google Fastflip?

    - by marcamillion
    Trying to get the same functionality as Google FastFlip. Not just with the thumbnails, but even for the larger images too. Notice how when you click on a story, you see the main story front and center, and you see smaller half-screens of previous and next stories. How can I get that functionality? Is there a plugin for one of the JS frameworks that does this already? I also love the speed and feel of flipping through the images.

  • Lazy-loading flash objects

    - by friedo
    I'm using the jQuery lazy-loading plugin to defer loading of below-the-fold images on a large web page. This works great. Now, I would like to apply the same technique to a large Flash object which is also below-the-fold. I don't think the lazy-load plugin handles things that aren't images (at least it doesn't look that way so far.) I may have to do it myself. In that case, how do I detect when the area containing the Flash object becomes visible?

  • Webbrowser javascript errors

    - by Gaby
    HI, I use a WebBrowser control to navigate to a html page which contains JavaScript. When I open this page in the IE browser no JavaScript error is shown and the page is displayed and functions perfectly. But when navigating to the same page with the WebBrowser control, a pop-up appears to inform about a Script error. I have tried to suppress the script error with the ScriptErrorsSuppressed property but now another pop-up comes up with the title "Visual Studio Just-In-Time Debugger" and proposes to debug. How can i disable all the errors?

  • How to control allowed HTML tags in WMD Editor?

    - by Toto
    I am trying to some-how set the valid HTML tags and attributes users would be able to use in WMD Editor in my site. For example, I want to forbid the user to directly set the font size, color, typeface and so on, which is trivial to do with the default settings typing something like: <span style="font-size: 45px; color:#FF0000">Some intrusive text here</span>. I think the way to implement this is through the "wmd_options", but I have not found any documentation or reference regarding this, giving the fact that the 'Options demo' seems to be the only public documentation and it does not show how should I do what I have described above. I've send this same question to [email protected] but didn't get any reply. As stackoverflow uses this editor someone reading this or maybe Jeff knows the answer ;) Thanks in advance!
