  • Simulate Offline Mode for HTML5 Cache Testing

    - by Kevin Sylvestre
    I have an HTML5 application that requires offline support. I am using a local Apache server for the application, and am trying to figure out what the best way is to simulate offline mode (currently, in Firefox I disable my Air-Port to simulate offline mode, but this is a pain). Any suggestions? I am open to using other browsers if a method exists that doesn't require turning off my Internet.

  • use jQuery to get 'true size' of image without removing the class

    - by jon3laze
    I am using Jcrop on an image that is resized with css for uniformity. JS <script type="text/javascript"> $(window).load(function() { //invoke Jcrop API and set options var api = $.Jcrop('#image', { onSelect: storeCoords, trueSize: [w, h] }); api.disable(); //disable until ready to use //enable the Jcrop on crop button click $('#crop').click(function() { api.enable(); }); }); function storeCoords(c) { $('#X').val(c.x); $('#Y').val(c.y); $('#W').val(c.w); $('#H').val(c.h); }; </script> HTML <body> <img src="/path/to/image.jpg" id="image" class="img_class" alt="" /> <br /> <span id="crop" class="button">Crop Photo</span> <span id="#X" class="hidden"></span> <span id="#Y" class="hidden"></span> <span id="#W" class="hidden"></span> <span id="#H" class="hidden"></span> </body> CSS body { font-size: 13px; width: 500px; height: 500px; } .image { width: 200px; height: 300px; } .hidden { display: none; } I need to set the h and w variables to the size of the actual image. I tried using the .clone() manipulator to make a copy of the image and then remove the class from the clone to get the sizing but it sets the variables to zeros. var pic = $('#image').clone(); pic.removeClass('image'); var h = pic.height(); var w = pic.width(); It works if I append the image to an element in the page, but these are larger images and I would prefer not to be loading them as hidden images if there is a better way to do this. Also removing the class, setting the variables, and then re-adding the class was producing sporadic results. I was hoping for something along the lines of: $('#image').removeClass('image', function() { h = $(this).height(); w = $(this).width(); }).addClass('image'); But the removeClass function doesn't work like that :P

  • Restricting Access in ERB code.

    - by LGFaler
    I am trying to build a CMS using ERB. Is there a way you can give ERB code read-only access to your models? For instance, I want to be able to load any information on my models (Model.all, Model.find_by_slug, Model.find_by_name, Model.other_model.name, etc...), but I don't want to be able to change this data. Can you disable ERB from executing commands that would make database changes (Model.save, Model.update, Model.delete, Model.destroy, etc.)???

  • how to dynamically break NHibernation cascade

    - by Joe Black
    The NHibernate cascade setting in the entity mapping is static. Is there anyway to dynamically disable the "cascade" setting in code to avoid expensive cascade operation in NHiberate during a bulky data transaction? We do not want to use stored procedures or native SQL because we need to have the entity changes captured by NHibernate (audit).

  • Restricting Edit and Delete in Ruby on Rails

    - by phleet
    I want to be able to edit and delete resources myself, but not allow users of the application to do so. Is there an easy way of doing this in Rails? An incomplete solution would be just to remove the "delete" and "edit" buttons from the index view, but that doesn't disable their ability to do so via direct HTTP requests. Running Rails 2.2.2 and ruby 1.8.7

  • UITextView disabling text selection

    - by dizy
    I'm having a hard time getting the UITextView to disable the selecting of the text. I've tried: canCancelContentTouches = YES; I've tried subclassing and overwriting: - (BOOL)canPerformAction:(SEL)action withSender:(id)sender (But that gets called only After the selection) - (BOOL)touchesShouldCancelInContentView:(UIView *)view; (I don't see that getting fired at all) - (BOOL)touchesShouldBegin:(NSSet *)touches withEvent:(UIEvent *)event inContentView:(UIView *)view; (I don't see that getting fired either) What am I missing ?

  • Shapes-tool creating a vector mask every time, cannot seem to fix in CS3?

    - by Bryan
    Every time I create a shape using the shape tool, it places a vector mask on top of this. I don't know how I enabled this but it does not do it on my laptop version, only my desktop. I can seem to disable this problem I am having. Even reinstalling and restoring defaults I cannot seem to stop this. Very frustrating, anyone have a fix for this problem? Thanks in advance!

  • How to fix emacs popup dialogs on mac?

    - by radekg
    Hello emacs gurus, I'm out of ideas here - my emacs crashes when popup dialog is opened. The x-popup-dialog function is probably to blame but I found no workaround to this. My Emacs version is 23.1.1 . Unfortunately some functionality of emacs calls this (e.x. customize asks whether it should save the changes) which causes the crash. Does anybody know how to fix it or disable it?

  • Sanitizing DB inputs with XSLT

    - by azathoth
    Hello I've been looking for a method to strip my XML content of apostrophes (') like: <name> Jim O'Connor</name> since my DBMS is complaining of receiving those. By looking at the example described here, that is supposed to replace ' with '', I constructed the following script: <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:output omit-xml-declaration="yes" indent="yes" /> <xsl:template match="node()|@*"> <xsl:copy> <xsl:apply-templates select="node()|@*" /> </xsl:copy> </xsl:template> <xsl:template name="sqlApostrophe"> <xsl:param name="string" /> <xsl:variable name="apostrophe">'</xsl:variable> <xsl:choose> <xsl:when test="contains($string,$apostrophe)"> <xsl:value-of select="concat(substring-before($string,$apostrophe), $apostrophe,$apostrophe)" disable-output-escaping="yes" /> <xsl:call-template name="sqlApostrophe"> <xsl:with-param name="string" select="substring-after($string,$apostrophe)" /> </xsl:call-template> </xsl:when> <xsl:otherwise> <xsl:value-of select="$string" disable-output-escaping="yes" /> </xsl:otherwise> </xsl:choose> </xsl:template> <xsl:template match="node()|@*"> <xsl:apply-templates name="sqlApostrophe"/> </xsl:template> </xsl:stylesheet> However, the processor isn't accepting it. What am I missing here? Is there a better way to get rid of the apostrophes? Perhaps another approach for sanitizing DB inputs by using XSLT? Thanks for your help

  • Does Ruby Version Manager interfere with the system scripts on Dream Linux?

    - by stephemurdoch
    Since Dream Linux has built in support for Ruby, I'm assuming it will work well as a Rails development environment, but I'm wondering if Ruby Version Manager will interfere with the system version of Ruby. Generally, when I use RVM, I disable/ignore the system version. How will the Dream Linux OS system scripts that are written in Ruby react to the presence of RVM? If I can't use RVM on Dream Linux, how easy is it to upgrade to newer versions of Ruby, without frazzling the system?
