  • Change cursor style in firefox input file tag

    - by JohnJ
    I have been trying to change the cursor style to look like a pointer rather than an I beam thing, but it looks like FF does not respect the cursor spec in an input file field. For example, I have made this small fiddle: http://jsfiddle.net/jDZtn/4/ where Id like the cursor to look like a pointer rather than an Ibeam when the user hovers over it. My end plan is to introduce opacity==0 and use a clickable button over it. I am not sure if this behaviour is a bug or not.

  • jQuery - making sure content is loaded before it's faded in?

    - by Kenny Bones
    Hi, Nick Craver really helped me out alot with this code in this thread http://stackoverflow.com/questions/2743443/jquery-can-someone-help-stitching-jquery-code-with-ajaxcomplete/2743791#2743791 And it is working. But I notice that there's a small delay after I've clicked a link and before the content is actually loaded. It's not very intense content that's loaded either so I think it's got something to do with the order which things happen in the script. The original code looks like this: $('.dynload').live('click', function(){ var toLoad = $(this).attr('href')+' #content'; $('#content').fadeOut('fast',loadContent); $('#ajaxloader').fadeIn('normal'); function loadContent() { $('#content').load(toLoad,'',showNewContent()) } function showNewContent() { $('#content').fadeIn('fast',hideLoader()); //Cufon.replace('h1, h2, h3, h4, .menuwrapper', { fontFamily: 'advent'}); } function hideLoader() { $('#ajaxloader').fadeOut('normal'); } return false; }); The new code looks like this: $(function() { $('.dynload').live('click', function(){ $('#ajaxloader').fadeIn('fast'); $('#ajaxloaderfridge').fadeIn('fast'); var href = this.href + ' #content'; $('#content').fadeOut('fast',function() { $(this).load(href,'', function(data) { createMenus(); $('#ajaxloader').fadeOut('fast'); $('#ajaxloaderfridge').fadeOut('fast'); $('#content').fadeIn('fast'); Cufon.replace('h1, h2, h3, h4, .menuwrapper', { fontFamily: 'advent'}); }); }); return false; }); }); $(createMenus); function createMenus() { $('#kontrollpanel .slidepanels').kwicks({ min : 42, spacing : 3, isVertical : true, sticky : true, event : 'click' }); } In the original code, #content is faded out, then the function "loadContent" is started. Which is basically what is happening in the new script as well isn't it? And when I was using the old code, the content just faded out and faded in really fast and smooth and with no small pause delay before the content arrived.

  • Accessing loop iteration in a sub-function?

    - by DisgruntledGoat
    I'm using the Google Maps API to plot several points on a map. However, in the click event function below, i is always set to 4, i.e. its value after iterating the loop: // note these are actual addresses in the real page var addresses = new Array( "addr 1", "addr 2", "addr 3", "addr 4" ); for (var i = 0; i < addresses.length; i++) { geocoder.getLatLng(addresses[i], function(point) { if (point) { var marker = new GMarker(point); map.addOverlay(marker); map.setCenter(point, 13); GEvent.addListener(marker, "click", function() { // here, i=4 marker.openInfoWindowHtml("Address: <b>" + addresses[i] + "</b>"); }); } }); } So when the marker displays it's using addresses[4] which is undefined. How do I pass the correct value of i to the function?

  • (closed) nodejs responding an image (via pipe and response.end()) leads into strange behaviour

    - by johannesboyne
    What the Problem was: I had 2 different writeStreams! If WriteStram#1 is closed, the second should be closed too and then it all should be piped... BUT node is asynchronious so while one has been closed, the other one hasn't. Even the stream.end() was called... well you always should wait for the close event! thx guys for your help! I am at my wit's end. I used this code to pipe an image to my clients: req.pipe(fs.createReadStream(__dirname+'/imgen/cached_images/' + link).pipe(res)) it does work but sometimes the image is not transferred completely. But no error is thrown neither on client side (browser) nor on server side (node.js). My second try was var img = fs.readFileSync(__dirname+'/imgen/cached_images/' + link); res.writeHead(200, { 'Content-Type' : 'image/png' }); res.end(img, 'binary'); but it leads to the same strange behaviour... Does anyone got a clue for me? Regards! (abstracted code...) var http = require('http'); http.createServer(function (req, res) { Imgen.generateNew( 'virtualtwins/www_leonardocampus_de/overview/28', 'www.leonardocampus.de', 'overview', '28', null, [], [], function (link) { fs.stat(__dirname+'/imgen/cached_images/' + link, function(err, file_info) { if (err) { console.log('err', err); } console.log('file info', file_info.size); res.writeHead(200, 'image/png'); fs.createReadStream(__dirname+'/imgen/cached_images/' + link).pipe(res); }); } ); }).listen(13337, '127.0.0.1'); Imgen.generateNew just creates a new file, saves it to the disk and gives back the path (link)

  • 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?

  • parseInt('07')=='7', but parseInt('08')=='0'? why?

    - by KOHb
    Here's a simple script that gives a strange result: alert(parseInt('01')+' - '+parseInt('02')+' - '+parseInt('03')+' - '+parseInt('04')+' - '+parseInt('05')+' - '+parseInt('06')+' - '+parseInt('07')+' - '+parseInt('08')+' - '+parseInt('09')+' - '+parseInt('10')); I would expect it to give 1 - 2 - 3 and so on, but it gives me this (in FireFox, Chrome and IE6): 1 - 2 - 3 - 4 - 5 - 6 - 7 - 0 - 0 - 10 Can someone please explain me why?

  • Get Caret Position within an Text Input field

    - by MarkB29
    How could can I get the caret position from within an input field. I have seen a few bits and pieces on google but nothing bullet proof. Basically something like a Jquery plugin would be ideal so I could simply do $("#myinput").caretPosition() I realise there may by other non-jQuery solutions and these would also be brilliant if anyone has any??

  • Trouble with Perfect Scrollbar jQuery

    - by coolpup
    I'm using the Perfect Scrollbar jQuery app (http://www.yuiazu.net/perfect-scrollbar/) for this site: http://thehummingbirdplace.com/ The scrollbar shows up when you hover over the News section, but it won't scroll down to reveal the content. I've used this scrollbar before successfully, so I'm stumped as to what is different now. I haven't been able to replicate this on a simpler page, when I experiment on another page it either works or just vanishes, so I'm not sure why it is successfully showing up, yet not scrolling on the main page. Any help would be appreciated!!

  • How do I automatically update hundreds of images in an HTML page using jquery?

    - by Chris
    I have an HTML page where I want to refresh a lot of images every 30 seconds after the HTML page has been downloaded. I understand how to do this with Jquery and a single image, but I want to use about 200 custom urls to determine the current image to display for over 200 images. I need to find an efficient way to have jquery call the custom url associated with each image to download the url for the needed image as it changes, and then update the image in the page when it changes. Current hyperlink example to demonstrate the custom urls. <A href="/urlThatReturnsCurrentImageURL/1234/4567">link to url for image</A> Each custom url will return an image tag like this (or any other text that makes this simpler for jquery) <img src="/static/someImage.jpg"> What is the simplest way to have jquery call the custom url for each image to download the image url, image html, or some other text that jquery can use to download the right image every 30 seconds? Please keep in mind that I will have about 200 of these on a page.

For example, if I click button where id is array[3] so id gets value of 3 in Jquery's function. Hope you got what I mean.

  • 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!

    - by TGuimond
    Hi all, I have been working on a shopping cart that the user can add/remove order items as they please and am returning an updated sub-total via a webservice using jQuery $.ajax Here is how I am calling the webservice and setting the sub-total with the response. //perform the ajax call $.ajax({ url: p, data: '{' + s + '}', success: function(sTotal) { //order was updated: set span to new sub-total $("#cartRow" + orderID).find(".subTotal").text(sTotal); }, failure: function() { //if the orer was not saved //console.log('Error: Order not deleted'); } }); The response I am getting seems perfectly fine: {"d":"128.00"} When I display the total on the page it displays as 128 rather than 128.00 I am fully sure it is something very simple and silly but I am so deep into it now I need someone with a fresh brain to help me out!!

  • Rendering ExtJs components without panels?

    - by Tower
    Hi, Take a look at this example: http://www.extjs.com/deploy/dev/examples/multiselect/multiselect-demo.html On it, there are components rendered against a panel. I've been searching for a way to render components without a panel, so that they are laid out against empty background directly, without any window-like panels. Is there a way to accomplish this?

  • Function to get the font and calculate the width of the string not working on first instance

    - by user3627265
    I'm trying to calculate the width of the string based on the font style and size. The user will provide the string, the font style and the font size, and then after giving all the data the user will hit the submit button and the function will trigger. Basically this script works but only when the submit button is hit twice or the font is selected twice,. I mean if you selec DNBlock as a font, it will not work for first time, but the second time you hit submit, it will then work. I'm not sure where is the problem here, but when I used the default font style like Arial, times new roman etc it works perfectly fine. Any Idea on this? I suspected that the font style is not being rendered by the script or something. Correct me if I'm wrong. Thanks //Repeat String String.prototype.repeat = function( num ) { return new Array( num + 1 ).join( this ); } //Calculate the width of string String.prototype.textWidth = function() { var fntStyle = document.getElementById("fntStyle").value; if(fntStyle == "1") { var fs = "DNBlock"; } else if(fntStyle == "2") { var fs = "DNBlockDotted"; } else if(fntStyle == "3") { var fs = "DNCursiveClassic"; } else if(fntStyle == "4") { var fs = "DNCursiveDotted"; } else if(fntStyle == "5") { var fs = "FoundationCursiveDots-Regul"; } var f = document.getElementById("fntSize").value.concat('px ', fs), o = $('<div>' + this + '</div>') .css({'position': 'absolute', 'float': 'left', 'white-space': 'nowrap', 'visibility': 'hidden', 'font': f}) .appendTo($('body')), w = o.width(); o.remove(); return w; } //Trigger the event $("#handwriting_gen").submit(function () { var rptNO = parseInt($('#rptNO').val()); $("[name='txtLine[]']").each(function(){ alert(this.value.repeat(rptNO).textWidth()); if(this.value.repeat(rptNO).textWidth() > 1000) { $(this).focus(); $(this).css({"background-color":"#f6d9d4"}).siblings('span.errorMsg').text('Text is too long.'); event.preventDefault(); } }); });

  • how to handle large dataset like sproutcore

    - by Nik
    Hello all, I really don't have any substantial code to show here, actually, that's kinda why I am writing: I looked at the SproutCore demo, especially the Collection demo, on http://demo.sproutcore.com/sample_controls/, and am amazed by its loading 200,000 records to the page so easily. I tried using Rails to provide 200,000 records and in a completely blank HTML page with <% @projects.each do |p| % <%= p.title % <% end % that freezes the browser for seconds on my m1530 laptop with 4gb ram and t7700 256gb ssd. Yet the sproutcore demo does not freeze and takes less than 3 seconds to load. What do you think the one technique they are using to enable this is? Thanks!

  • 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?

  • Creating a page selector with JSP/JSTL

    - by zakSyed
    I am working on a project where I am required to build a page somewhat similar to the one you see when you visit a website like blockbuster. When you click on browse more you are taken to a page with a bar on top with different page numbers and a drop down to select the number of pages you want to view on that page. I want to include a feature like that on my page but I am not sure where to start. In my page I have list of 200 items which I want to display page by page. I was suggested to use custom tags, but is there a more simpler or efficient way to create that functionality. My web application uses Spring MVC framework and is coded entirely in Java. Any suggestions will be appreciated.

  • Find all radio groups which haven't been selected

    - by nickf
    I have a basic quiz/survey type application I'm working on, and I'd like to give the user a prompt before they submit if they haven't answered all the questions. All the questions are multiple choice using radio buttons: <div class="question"> Q1: What is the second letter of the alphabet? <div class="choices"> <input type="radio" name="question_1" value="1" /> A <input type="radio" name="question_1" value="2" /> B <input type="radio" name="question_1" value="3" /> C </div> </div> <div class="question"> Q2: Which out of these is a berry? <div class="choices"> <input type="radio" name="question_2" value="1" /> Apples <input type="radio" name="question_2" value="2" /> Bananas <input type="radio" name="question_2" value="3" /> Carrots </div> </div> <div class="question"> ...etc How do you find which groups haven't got an option ticked? Or at least, if there are any which haven't been answered? jQuery is ok, and even preferred.
