  • Can a function defined in a bookmarklet be called from a page-level script?

    - by Soviut
    I have a bookmarklet that needs to open a new window/tab. In order to avoid the popup blocker, I need to call the window.open() method directly in the bookmarklet ie: at the browser-level. However, I want to keep the bookmarklet updatable by loading external Javascript files. To do this, the bookmarklet needs to append script nodes to the DOM. If i were to put window.open() code in one of these externally loaded scripts, the popup blocker would block it since its page-level. What I want to know is if I can create a wrapper function around window.open() in my bookmarklet, then call it from the externally loaded script? What is the scope and what are the permissions on a wrap such as this?

  • RSpec: in-depth differences between before(:all) and before(:each)

    - by gmile
    Ok, so I've ran into a very strange issue, directly connected with before blocks. I'm doing a integration testing via Watir and RSpec. For a simple test to check if user can perform a login I'm creating a 'user' record in the db by means of factory_girl. So I put the following code: before(:each) do @user = Factory(:user) end if "should perform a login" do # do stuff end In do stuff I call a browser and see how the user tries to login. Unfortunately, somehow he cannot do that — "Username isn't valid". After some investigation I discovered that if I put the code for creating user in before(:all) block, everything magically works. How's that? What's the difference between :all and :each in this context? Also, If I put the code for creating user actually in the test body, it still doesn't work (i.e. user somehow isn't added to the DB or something).

  • why is link generated in YUI javascript failing to render in rails?

    - by pmneve
    Using YAHOO.widget.treeview to generate a table with three levels of data: module, submodule, and detail. If there is an image associated with a detail row the javascript generates a link: "<td><a href=\"/screenshot/show/" + rowData.id + "\">Screenshot</a></td>" that is appended to the html for the row. The url is generated correctly and the link appears. When clicked nothing happens except the word 'Done' appears in the browser status bar. Am calling the very same url from another page that does not use javascript and the screenshot page appears as expected. Here is the controller. class ScreenshotController < ApplicationController def show if @detail.screen_path.length 1 @imagePath = "#{RAILS_ROOT}" + "/private/#{Company.find(@detail.company_id).subdir}/" + "#{Project.find(@detail.project_id).subdir}/screenshot/" + "#{@detail.screen_path}" send_file ( @imagePath, :type = 'image/jpeg', :disposition = 'inline') end end end A sample url: http://localhost:3004/screenshot/show/20854 This code from show.html.erb belonging to the detail model works: <%= link_to 'View', :controller = 'screenshot', :id = @detail.id, :action = 'show' % Any ideas???

  • how to define div or table cell height depending on the height of other divs or cells

    - by John
    I want to have a web page that contains 3 parts: A header at the top of the page , a footer (both of which having specific height in px)and the main part of the page which should be a div or table cell with the appropriate height attribute in order to take all the available space between them. I want the page to take 100% of the browser window height, trying to avoid scrollbars. The problems I have are the following: USING DIVs a) If I set the maindiv height to 100%, the page overflows and I get a vertical scrolbar. (the maindiv's height is set to the 100% of the browser window) <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>Untitled Document</title> </head> <style type="text/css"> <!-- body, html{ height: 100%; max-height:100%; width: 100%; margin:0; padding:0; } div{padding:0;margin:0;} #containerdiv{height:100%;width:100%;background-color:#FF9;border:0;} #headerdiv{height:150px;width:100%;background-color:#0F0;border:0;} #footerdiv{height:50px;width:100%;background-color:#00F;border:0; } #maindiv{ background-color:#F00; height:100%; } div{border:#000 medium solid;border:0;} </style> <body> <div id="containerdiv"> <div id="headerdiv">headerdiv</div> <div id="maindiv">maindiv</div> <div id="footerdiv">footerdiv</div> </div> </body> </html> b) If I set the maindiv height to auto, the maindiv height is depending on it's content, which is not what I want. USING tables a) If I set the main cell height to 100% it works fine with Firefox but in Internet Explorer 8 I get a vertical scrollbar (you can use the next code block using th style="height:100%" instead of "auto" to see this.) b) If I set the main cell to auto it seems to be working both in IE and FF but then I have the problem that anything I put inside the maincell (table or div) cannot get maincell's full height in IE. <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>Untitled Document</title> </head> <style type="text/css"> <!-- body, html, table{ height: 100%; width: 100%; margin:0; padding:0; } table{border:#000 0px solid} </style> <body> <table style="background:#063" cellpadding="0" cellspacing="0" border="0"> <tr><th style="height:150px;background-color:#FF0"></th></tr> <tr> <th style="height:auto"><table style="background:#0FF;" cellpadding="0" cellspacing="0" border="0"><tr><th style="height:auto">nested cell</th></tr></table> </th> </tr> <tr><th style="height:50px;background-color:#FF0"></th></tr> </table> </body> </html> </html> Any ideas? Maybe there is an easier way to define the size of the main part of the page in px using javascript? (my javascript skills are pretty poor so any help with this is welcome!)

  • html/php: how to handle absolute url's?

    - by YuriKolovsky
    Is the html tag safe to use in terms of browser support? Or should I generate a root path with PHP which i then add like this <a href="<?=BASE?>somepage.html">somepage</a> which makes up a absolute url. using the base tag like this <base href="<?=BASE?>" /> I am then able to use links like this <a href="somepage.html">somepage</a> now I am fully aware that it would be much easier to just do this without using the base tag: <a href="/somepage.html">somepage</a> but how do I test locally then with a base url of http://localhost/testsite/ ???

  • Using vim, how do you quickly refresh a web page you're working on?

    - by aLostMonkey
    I've been using VIM for a few weeks now while messing with various web languages and I'm really enjoying it. I find it cumbersome having to tab or click into my browser and refresh the page to see the effect of a code change. It's even more annoying as I'm using Virtual Box and I tend to be working from PDF files on the host system so I have limited window space. Do you gurus have any fancy ways of doing this? I was wondering if it's possible to split the VIM workspace and have links/lynx in a window of its own or something to that effect?

  • jQuery.Form wont submit

    - by kim
    Im´trying to submit a form without refreshing the page, but I´m having a problem. When I click submit the page refreshes and anothing gets posted. Here is the code, what am I doing wrong? (I´m a newbie) jQuery 1.4.2 and the jQuery Form Plugin 2.43 is present. tnx $(document).ready(function() { var options = { target: '#output2', url: https://graph.facebook.com/<%=fbUid%>/feed, type: post, clearForm: true // clear all form fields after successful submit //dataType: null // 'xml', 'script', or 'json' (expected server response type) //resetForm: true // reset the form after successful submit // $.ajax options can be used here too, for example: //timeout: 3000 }; // bind to the form's submit event $('#fbPostStatus').submit(function() { // inside event callbacks 'this' is the DOM element so we first // wrap it in a jQuery object and then invoke ajaxSubmit $(this).ajaxSubmit(options); // !!! Important !!! // always return false to prevent standard browser submit and page navigation return false; }); });

  • What is the best way to inject a javascript script from another domain into a page? (without using a

    - by lowellk
    Here is a snippet of javascript for loading a script onto a given page asynchronously. I was wondering if there was anything wrong with it? Can it be improved? I haven't played with this yet, but some things I'm worried about are: - cross browser support - when script.readyState is true, will the old version of that function get clobbered? - can i always count on there being a head or body element? Here it is: function injectScript(url, callback){ var script = document.createElement('script'); script.type = "text/javascript"; script.setAttribute('async', 'true'); script.src = url; (document.getElementsByTagName('head')[0] || document.getElementsByTagName('body')[0]).appendChild(script); if (callback) { if (script.readyState){ script.onreadystatechange = function(){ if(script.readyState === "loaded" || script.readyState === "complete"){ script.onreadystatechange = null; callback(); } }; }else{ script.onload = function() { callback(); } } } }

  • Socket server for 2D MMORPG

    - by Alejandro
    I'm starting a 2D browser multiplayer game consisting of a city with many kinds of transports (metro, buses, tunnels), players using those transports and having some interaction between them. I have started the client side in Actionscript, server side in PHP (but now i'm moving to Java) and persistence in MySQL. Which socket server (non commercial) will be preferable, RedDwarf (former DarkStar), Red5, ... ? Those servers are Flash Remoting (AMF) capable ? Those servers manage all the object's game persistence? Then there's no need to create a database ?

  • Android DownloadManager - few questions

    - by ChrisR
    I have a few questions about the Android browser download manager . Does it support multiple downloads at the same time? From the code it looks like it does. What's advantage of using HTTPRequest over URL/URLConnection to download files? 3.The download manager opens and closes connection for each download. Is it the right thing to do? Or is it better to use the same connection for for all the download requests(by changing the required parameters) and then clse the connection?

    - by memical
    Hi, on a web page i am trying to redirect the browser to another page on the same site. the code is very simple for that: window.location = "/path1/path2" on safari - both windows as well as mac - a message box containing only the text "http://domain.com" comes up. I have tried different ways of specifying this: location.href, windows.assign(...) ... and the all have the same behavior. Did any of you see this? and do you have a solution for this? Thanks.

  • Socket Programming for the Web

    - by Benny
    I have to interact with a legacy system that accepts socket communication and messages. My goal is to make the application cross-platform, but I need the ability to push messages to the client (i.e. - .NET's WCF, Java's Comet) and detect when the user closes out of their browser to destroy the socket. I have built a prototype of .NET wrapper + WCF + Silverlight but it is so disconnected it is difficult to manage the state of the user and seems to be a nightmare to support. All of that considered, what would be my best option?

  • How to use separat block caches for secure and unsecure shop access in Magento?

    - by Uwe Mesecke
    I use the Magento block cache for the top navigation block. The problem is the block has to generate some urls for files in the skin directory that cannot be put into css files as the file names depend on category model data. Now when I open magento using a secure connection (https://) the navigation block is fetched from the cache and is sent to the browser but with the http:// urls resulting in a warning in most browsers about unsecure elements on the page. I'd like the have separat caches for secure and unsecure connections. The navigation block extends the class Mage_Catalog_Block_Navigation and therefore has the following cache configuration: $this->addData(array( 'cache_lifetime' => false, 'cache_tags' => array(Mage_Catalog_Model_Category::CACHE_TAG, Mage_Core_Model_Store_Group::CACHE_TAG), ));

  • Non-Latin characters in URLs - is it better to encode them or replace with their Latin "counterparts

    - by Pawel Krakowiak
    We're implementing a blog for a site which supports six different languages and five of them have non-Latin characters in their alphabets. We are not sure whether we should have them encoded (that is what we're doing at the moment) Létání s potravinami: Co je dovoleno? becomes l%c3%a9t%c3%a1n%c3%ad-s-potravinami-co-je-dovoleno and the browser displays it as létání-s-potravinami-co-je-dovoleno. or if we should replace them with their Latin "counterparts" (similar looking letters) Létání s potravinami: Co je dovoleno? becomes letani-s-potravinami-co-je-dovoleno. I can't find a definitive answer as to what's better from SEO perspective? Search engine optimization is very important for us. Which approach would you suggest?

  • Detect all changes to a <input type="text"> (immediately) using JQuery

    There are many ways the value of a <input type="text"> can change, including: keypresses copy/paste modified with JavaScript auto-completed by browser or a toolbar I want my JavaScript function to be called (with the current input value) any time it changes. And I want it to be called right away, not just when the input loses focus. I'm looking for the cleanest and most robust way to do this across all browsers (using jQuery preferably). Example use case: On the Twitter Signup page, the username field's value gets shown in the url "http://twitter/username" below it.

  • Display indented XML code within a HTML page

    - by Efrain
    I have a programmatically created HTML document on which I would like to show some XML-code, fully formatted with line breaks and tabulators. That is, it should look like if you drag an xml file without a xml-stylesheet directly onto your browser (most browsers do some kind of xml-rendering with some default style sheet). Now, I can of course escape all the characters (like <>, tab and newline) and do the indenting myself (using css styles, for example), but I was wondering whether I couldn't re-use some 'default' xml-stylesheet from somewhere. Preferrably also one that has some javascript node-folding, too. Do you know such a stylesheet/xslt? Or would you suggest another way to achieve this? I'm using C#. PS: I tried to use the XmlNotepad.DefaultSS.xslt from Microsoft's XmlNotepad, but I couldn't really get that working. :T

  • Cant append "used" DOMObject in IE

    - by Kein
    I have some objects, that keep created DOMObjects, like here: function category(){ var domBlock; this.block = function(){ if (!domBlock){ // Here dom-object constructor $('<div></div>'); etc } return domBlock; // jquery object, // but i test and native document.createElement } } Then i clear category's area, and append old and new received(with Ajax) objects: area.html(''); for(id in category_list){ area.append( category_list[id].block() ); } where category_list is list that contain category objects. Area is jQuery object. In other browsers (except IE) i get area with all needed categories, but in IE i get only new received categories(that just create DomObject), other old objects that keeped old DomObject not show. I know it possible make with innerHTML, but i wont keep DomObject, not text. Because DomObject keep many events. And it very hard for browser attach events for each DomObject after refresh area.

  • SoundManager + FFMPEG causing loud popping sound when streaming MP3s?

    - by David
    Hi there, I built an application that plays both uploaded original mp3 files, and copies that have been converted with FFMPEG. I am finding that in some cases the FFMPEG files have a horrible popping/clicking/screeching sound for a split second at startup (hear below). But when I analyze the file in an audio editor there is nothing there, so it seems to be either the browser or soundManager reacting badly to something in that file. Wondering if there is any way I can fix this either by adjusting FFMPEG settings, soundManager settings, or..... Any suggestions? I've uploaded the offending sound in the link below (before the music starts playing). Thanks for your help! Hear sound
