  • IndexedDB and Relationships

    - by Josh Johnson
    Can I create relationships between my object stores in IndexedDB? For example, I have two object stores: artist and album. An artist has a one-to-many relationship with an album. album.artistId relates the album to artist.id. I'm thinking along the lines of Hibernate here. I would like to do a query for artists and have the albums belonging to that artist returned as an array called artists on the album object. artist.albums = [];

  • Get Flickr Sets

    - by PaulAdamDavis
    Hi everyone. Usual stuff, Googled forever, looked on here, no help. Yet. What I want is to list the sets of photos I have on Flickr. Nice & simple, it would seem. I want the 'title image' (the one used as the thumb for it on Flickr its self), the title and URL. Can't be that hard, can it? The language of choice is PHP (5.1.6), or JS (jQuery if possible). Both are good.

  • jQuery - Programmatically Trigger Event

    - by Sonny
    I need to programmatically trigger a click event that's being handled by jQuery. Here's the current code: var $thumbs = $('#PhotoGalleryThumbs .tile'); var $zoom = $('#PhotoGallery #PhotoGalleryZoom img'); var $description = $('#PhotoGallery #PhotoGalleryDescription'); $thumbs.click(function(event) { event.preventDefault(); var $thumb = $(this); $thumb.addClass('selected') .siblings().removeClass('selected'); $zoom.attr('src', $thumb.children('a').attr('href')); $description.html($thumb.find('img').attr('alt')); }); I am having a mental block working out how to create a function out of the event handling code and then arbitrarily calling it for an element in the $thumbs object.

  • Has anyone used a rails gem for lightbox functionality? If so which ones?

    - by bgadoci
    Trying to figure out what is the best solution for using lightbox in rails. I have a set up an application that has projects and posts belong_to project. A post can have multiple photos and I am successfully only displaying the first photo in the photos table in the projects show view for each post. I am now trying to allow the user to view the rest of the photos associated with a post through a lightbox feature. Any idea if there is a rails ready solution for something like this?

  • JQuery Facebook like Tag feature

    - by Tech
    Hi, Does anyone know of a very basic tag JQuery script? (Facebook like tag feature) All I want to do is when I type @ in a text box for it to search an AJAX search, it then brings back a display name i.e. "Bob Johnson" and an associated Id and stores the Id in a comma delimited list. So an example would be the following .... [TextArea] [Name 1] [Name 2] [Name 3] The thing is it also needs to remove this entry (Id) once the tag gets removed, also it needs to load into a DIV which has a scrollbar so that the list doesn't get to big. If anyone know's how/if this is possible that would be great. Thanks.

  • Event when the user changes font size in browser?

    - by Christian
    I need to get informed when the user changes the font size in it's browser. I need it to reposition some elements which have to be relative in one dimension to an anchor inside a text. So far i haven't found anything and i'm a bit worried that it's not possible. In this case it should be possible to emulate it with a hidden div and some text inside and a script polling for changes of it's width. But i hope someone has a more elegant solution.

  • JQuery tools overlay opens at the top of page instead of overlaying in IE, works fine in FF/Chrome

    - by culov
    Here is the sandbox version of my site: http://3.latest.truxmapper.appspot.com/ To reproduce the error, hover over to the toolbar and go to Support -- FAQ. In Chrome/FF, this will work as expected. In IE, the background image will quickly move to the center of the page, but when its time to insert the div over the background image, its inserted on top of the page rather than the center of the page. The plugin example ( http://flowplayer.org/tools/overlay/apple.html ) works fine in IE, so i know it ought to be possible. I've tried messing around with the div placement on the html and with the css to no avail. Does anyone know what could be the problem? Thanks!

  • Using "null" in jQuery functions. Is this okay?

    - by Nick
    My database consists of some entries which are NULL (so they don't affect max, min, etc..). When I pull all of the data from the database, I need to repopulate form fields with the values. Using .val(value) where value = NULL seems to work without any problems, but I'm not sure if this is a valid way to go about this. It doesn't say anything in the jQuery documentation (that I can find) about using NULL as parameters to functions.

  • How do I unbind another jQuery function on .click()?

    - by Mike Barwick
    I have this script that run to fix my menu bar to the browser on scroll. Nothing really needs to change here (works as it should). However, you may need it... var div = $('#wizMenuWrap'); var editor = $('#main_wrapper'); var start = $(div).offset().top; $(function fixedPackage(){ $.event.add(window, "scroll", function() { var p = $(window).scrollTop(); $(div).css('position',((p)>start) ? 'fixed' : 'static'); $(div).css('top',((p)>start) ? '0px' : ''); //Adds TOP margin to #main_wrapper (required) $(editor).css('position',((p)>start) ? 'relative' : 'static'); $(editor).css('top',((p)>start) ? '88px' : ''); }); }); Now for the issue at hand. I have another script function that calls a modal pop-up (which again works as it should). However, it's not slick from a UI perspective when I scroll the page when the modals open. So I want to disable the script above when the modal script below is called. In other words, when I click to open the modal pop-up, the script above shouldn't work. $(function () { var setUp = $('.setupButton'); // SHOWS SPECIFIED VIEW $(setUp).click(function () { $('#setupPanel').modal('show'); //PREVENTS PACKAGE SELECT FIXED POSITION ON SCROLL $(setUp).unbind('click',fixedPackage); }); }) As you can see above, I tried to unbind the scroll function (the first code snippet), but this is not correct. These two scripts are in two separate js libraries.

  • How to focus next field if user clicked on the link?

    - by LA_
    I have a number of fields with labels-links like below: <div class="control-group"> <label class="control-label" for="some-id-1"><a href="http://example.com/some-id-1" target="_blank">Text1</a></label> <div class="controls"> <input type="text" id="some-id-1" name="some-id-1"><br> </div> </div> <div class="control-group"> <label class="control-label" for="some-id-2"><a href="http://example.com/some-id-2" target="_blank">Text2</a></label> <div class="controls"> <input type="text" id="some-id-2" name="some-id-2"><br> </div> </div> If user clicks on the link, how can I focus according field (without preventing default action)? I.e. if user clicks on Text1, then I should open http://example.com/some-id-1 in new window and set focus at input with id some-id-1.

  • getAttribute cannot return class in IE7?

    - by Nir
    I need to find random nodes according to random attribute values. To do that I use getAtrribute on nodes from getElementsByTagName. It seems like when I look for class name as attribute it does not work on IE (works on FF). Anyone know if getAtrribute doesn't work only on 'class' or other attributes as well? (if its only class I'll do a workaround.)

  • jquery, position 'close icon' div in the top right of a large image

    - by Blankman
    My webpage has a large image (a map). I want to position, at the top right of the image, a small icon that is for closing the map. How can I figure out the position and place the image appropriately? The image has a fixed width of 900 x 600. I have jquery on the page if that helps. I tried using $("#map").position and I have the top and left, but not sure how to position to the top right.

  • Highlighting current and previous stars on mouseover

    - by mpet
    I'm trying to make simple five star rating system using Twitter Bootstrap 3 i jQuery. For now, I'm trying to set .hover() and .mouseout() events using counter by writing this code that doesn't work: var i; for (i = 1; i <= 5; i++) { $('#overall_rating_' + i).hover(function(){ $('#overall_rating_' + i).removeClass("glyphicon-star-empty").addClass("glyphicon-star"); }); $('#overall_rating_' + i).mouseout(function(){ $('#overall_rating_' + i).removeClass("glyphicon-star").addClass("glyphicon-star-empty"); }); } Trying to highlight current and previous stars on mouseover. The code is not complete, it would be accompanied by additional sub-counters, but this part doesn't work for now. Any better methods are welcome. What's broken here?

  • Detect if Download is Complete

    - by user604138
    I have a very simple and standard PHP force download script. How do I check if/when the download has completed in order to notify the user on the clientside? I don't even need to show the progress in real time, I am only interested in the very specific event: "when the download completes". Based on my research, it seems like it would have to be determined from the serverside as there is noondownloadready event and I don't think it is possible to intercept browser events. So it seems that my best bet would be to compare bytes sent to total bytes with some sort of clientside/severside interaction. How would I go about checking the bytes sent from the server for a PHP forced download? is there some sort of global PHP variable that store these data that I can ping with AJAX? <?php header("Content-Type: video/x-msvideo"); header("Content-Disposition: attachment; filename=\"".basename($realpath)."\";"); ... $chunksize = 1 * (1024 * 1024); // how many bytes per chunk if ($size > $chunksize) { $handle = fopen($realpath, 'rb'); $buffer = ''; while (!feof($handle)) { $buffer = fread($handle, $chunksize); echo $buffer; ob_flush(); flush(); } fclose($handle); } else { readfile($realpath); } exit(); ?> The reason I need this: For the project I am working on, it is required that after the download starts, the page redirects to (or displays) a "please wait while the download completes" page. Then, once it is complete, it should redirect to (or display) a "Your download is complete, thank you" page. I am open to other ideas that would achieve the same result.

  • Calling multiple functions simultaneously with jquery.

    - by clarke78
    I want to loop through an object that contains functions which will execute one after another. My most ideal approach would be to have these chain somehow (ie. func2 waits for func1 and func3 waits for func2) but this needs to happen dynamically and the functions will all have different durations. I'm using jQuery so I thought that perhaps "queue()" may help but I haven't worked with it much. A main concern is to not add any scope/callbacks to the functions within the object. I'd rather somehow enclose them within a parent function to execute within the loop in order to create the callback/chaining. Here's an example of what I've got now, but dumbed down. Thanks for any help! var obj = [ {'name':'func1','callback':function(){ alert(1); }}, {'name':'func2','callback':function(){ alert(2); }}, {'name':'func3','callback':function(){ alert(3); }} ]; $.each(obj, function(x, el) { el.callback(); });

  • jQuery .height() property not working

    - by Andrew
    I'm attempting to get the height of an element using jQuery, but am receiving some unexpected results. Here's the code: $(function() { var contentheight = $('#subpage-content-small').height; alert(contentheight); }); Where #subpage-content-small has these CSS properties: #subpage-content-small { width: 400px; float: left; margin: 30px 10px 0 0; padding-bottom: 45px; } What I'm getting as an output for my alert is the following: function (f) { var e = this[0]; if (!e) { return f == null ? null : this; } if (c.isFunction(f)) { return this.each(function (j) {var i = c(this);i[d](f.call(this, j, i[d]()));}); } return "scrollTo" in e && e.document ? e.document.compatMode === "CSS1Compat" && e.document.documentElement["client" + b] || e.document.body["client" + b] : e.nodeType === 9 ? Math.max(e.documentElement["client" + b], e.body["scroll" + b], e.documentElement["scroll" + b], e.body["offset" + b], e.documentElement["offset" + b]) : f === w ? c.css(e, d) : this.css(d, typeof f === "string" ? f : f + "px"); } Any idea why I'm getting this as opposed to an integer of the height? Thanks in advance!

  • auto_complete plugin error: Couldn't find Question with ID=auto_complete_for_tag_tag_name

    - by bgadoci
    I have successfully set up this plugin before so I am curious as to what I am doing wrong here. I have built the ability for users to add tags to questions. I am not using tagging plugin here but that shouldn't matter for this. With respect to the auto complete, I am trying to have the form located in the /views/questions/show.html.erb file access the Tags table and display entries in the tags.tags_name column. When I begin to type in the field I get the following error message: Processing QuestionsController#show (for 127.0.0.1 at 2010-05-31 15:22:20) [GET] Parameters: {"tag"=>{"tag_name"=>"a"}, "id"=>"auto_complete_for_tag_tag_name"} Question Load (0.1ms) SELECT * FROM "questions" WHERE ("questions"."id" = 0) ActiveRecord::RecordNotFound (Couldn't find Question with ID=auto_complete_for_tag_tag_name): app/controllers/application_controller.rb:15:in `init_data' For some reason I am actually passing the field name as the Question.id. The plugin set up is fairly simple as you add the following line to your controller: auto_complete_for :tag, :tag_name and the following line in your routes.rb file: map.resources :tags, :collection => {:auto_complete_for_tag_tag_name => :get } I have added the controller line to both my tags and questions controller and also mapped resources for both tags and questions in my routes.rb file: map.resources :tags, :collection => {:auto_complete_for_tag_tag_name => :get } map.resources :questions, :collection => {:auto_complete_for_tag_tag_name => :get } I have played around with removing either or of the above but can't seem to fix it. Any ideas what I am doing wrong here?
