  • JCarousel scroll method does not always fire

    - by Scott Faisal
    var carousel = jQuery('#mycarousel').data('jcarousel'); var index = carousel.size() + 1; carousel.size(index); var html = '<li> some html </li>'; carousel.add(index, html); carousel.scroll(index, 1); The very last scroll method fires but not always. Is this a bug in JCarousel? The following is the code for the scroll method in JCarousel: /** * Scrolls the carousel to a certain position. * * @method scroll * @return undefined * @param i {Number} The index of the element to scoll to. * @param a {Boolean} Flag indicating whether to perform animation. */ scroll: function(i, a) { if (this.locked || this.animating) return; this.animate(this.pos(i), a); }

  • SVG drawing application with vector export

    - by Bram Jetten
    I want to create a drawing application where I can place text and images on a canvas. Those elements also need to be interactively manipulated. Eventually the resulting canvas has to be exported to a vector based PDF. An excellent contender for this functionality would be SVG. However, this application also needs to be crossbrowser compatible. I've been browsing around for some time now and have seen a couple of solutions available. I found among others RaphaelJS and Google's SVGWeb for working with SVG. Now for converting those SVG files to a PDF I'm not sure if for instance Batik will offer me what I am looking for. Also, how would bitmap images be handled when converting the SVG to PDF?

  • Difficulty with MooTools Class.extend

    - by Erin Drummond
    Consider the following code: var Widget = new Class({ Implements: [Options], options: { "name" : "BaseWidget" }, initialize: function(options) { alert("Options are: " + JSON.stringify(options)); //alerts "Options are: undefined" this.setOptions(options); alert("My options are: " + JSON.stringify(this.options)); //alerts "My options are: { 'name' : 'BaseWidget' }" }, getName: function() { return this.options.name; } }); var LayoutWidget = Widget.extend({ initialize: function() { this.parent({ "name" : "Layout" }); } }); alert(new LayoutWidget().getName()); //alerts "BaseWidget" I am having difficulty in determining why the argument passed in the "this.parent()" call in "initialize" function of LayoutWidget is coming through as "undefined" in the initialize function of Widget. I am using MooTools 1.2.2. Would somebody be able to point me in the right direction?

  • Get status of servlet request before the response is returned

    - by Alex
    Good evening, I am in the process of writing a Java Servlet (Struts 2, Tomcat, JSP etc) which is capable of doing some fairly complex simulations. These can take up to 2 minutes to complete on the and will return a graph of the results. It is trivial to calculate the percentage of the simulation completed because the process works by repeating the same calculations 1000s of times. I would be interested to know if anyone has ever tried to use client side technology to provide any estimate of the percentage complete. I.e query the servlet processing to get the number of cycles completed at various point throughout the simulation. This could then be displayed as a bar in the client browser. Any thoughts, advice, resources would be much appreciated. Thanks, Alex

  • Is it possible to execute a function in Mongo that accepts any parameters?

    - by joshua.clayton
    I'm looking to write a function to do a custom query on a collection in Mongo. Problem is, I want to reuse that function. My thought was this (obviously contrived): var awesome = function(count) { return function() { return this.size == parseInt(count); }; } So then I could do something along the lines of: db.collection.find(awesome(5)); However, I get this error: error: { "$err" : "error on invocation of $where function: JS Error: ReferenceError: count is not defined nofile_b:1" } So, it looks like Mongo isn't honoring scope, but I'm really not sure why. Any insight would be appreciated. To go into more depth of what I'd like to do: A collection of documents has lat/lng values, and I want to find all documents within a concave or convex polygon. I have the function written but would ideally be able to reuse the function, so I want to pass in an array of points composing my polygon to the function I execute on Mongo's end. I've looked at Mongo's geospatial querying and it currently on supports circle and box queries - I need something more complex.

  • Firefox DOMContentLoaded event problem

    - by mck89
    Hi, i've created a script that works with the Dom so it has to wait until the Dom is ready before execute every operation. I want that this script can be included in two ways: In the head tag so that it is loaded before the Dom is ready. I've used document.addEventListener("DOMContentLoaded",function(){...},false) for this and it works well Loaded dinamically when the Dom is already loaded. In this case the script doesn't work because for some reasons if the Dom is already loaded the DOMContentLoaded event isn't fired So i want to know, is there a way to check if the Dom is already loaded so that the script can execute the code without using the DOMContentLoaded event?

    - by PavelBY
    I have html, and jquery for sorting my table (also there is non-standart sorting (with multi-tbody)). My code could be found here: http://jsfiddle.net/GuRxj/ As you can see there, td with prices (on russian ????) are sorted ascending (but tech-as not!? why? (it a question too))... But as you see, i need to send this tr's with prices to top of this tbody (now there are in the bottom), while empty-price-tr send to bottom... How to do this? part of js: $('.prcol').click(function(e) { var $sort = this; var $table = $('#articles-table'); var $rows = $('tbody.analogs_art > tr',$table); $rows.sort(function(a, b){ var keyA = $('td:eq(3)',a).text(); var keyB = $('td:eq(3)',b).text(); if (keyA.length > 0 && keyB.length > 0) { if($($sort).hasClass('asc')){ console.log("bbb"); return (keyA > keyB) ? 1 : 0; } else { console.log(keyA+"-"+keyB); return (keyA > keyB) ? 1 : 0; } } }); $.each($rows, function(index, row){ //console.log(row); $table.append(row); //$("table.123").append(row); }); e.preventDefault(); });

  • Why does an onclick property set with setAttribute fail to work in IE?

    - by Aeon
    Ran into this problem today, posting in case someone else has the same issue. var execBtn = document.createElement('input'); execBtn.setAttribute("type", "button"); execBtn.setAttribute("id", "execBtn"); execBtn.setAttribute("value", "Execute"); execBtn.setAttribute("onclick", "runCommand();"); Turns out to get IE to run an onclick on a dynamically generated element, we can't use setAttribute. Instead, we need to set the onclick property on the object with an anonymous function wrapping the code we want to run. execBtn.onclick = function() { runCommand() }; BAD IDEAS: You can do execBtn.setAttribute("onclick", function() { runCommand() }); but it will break in IE in non-standards mode according to @scunliffe. You can't do this at all execBtn.setAttribute("onclick", runCommand() ); because it executes immediately, and sets the result of runCommand() to be the onClick attribute value, nor can you do execBtn.setAttribute("onclick", runCommand);

  • Unique element ID to reference later

    - by Hanpan
    I'm trying to figure out a method of storing a unique reference to each tag on a particular page. I won't have any ability to edit the page content and I'll the generated UID to stay the same on every page refresh. Since browsers don't generate any kind of UID for elements, I was thinking that the only method to do this would be to execute a script which walks the DOM and creates a UID for each it comes across. I don't know how accurate this will be, especially considering I'll need to ensure it creates the same UID for the tag each time the script crawls the page. Can anyone think of any other, more accurate ways of mapping a page? Many thanks.

  • How can i have a div stuck on the left side of the page no matter how much i scroll horizontally?

    - by Noor
    This is kind of difficult to explain so ill link to a page that has the effect i need; http://wpaoli.building58.com/wp-content/uploads/2009/08/feedback-panel.html The feedback thing on the left side is what im trying to implement on my side, instead of feedback im going to use it as a navigation menu that shows up when clicked on. the things above is what i have right now. my problem is when i scroll to the right ( my page is around 6000px wide ) i want it to stay on the left side, is there a way to pull this off? (this is to much for my brain to handle)..thanks!

  • How to reference a specific object in an array of objects using jTemplates

    - by Travis
    I am using the excellent jTemplates plugin to generate content. Given a data object like this... var data = { name: 'datatable', table: [ {id: 1, name: 'Anne'}, {id: 2, name: 'Amelie'}, {id: 3, name: 'Polly'}, {id: 4, name: 'Alice'}, {id: 5, name: 'Martha'} ] }; ..I'm wondering if it is possible to directly specify an object in an array of objects using $T. (I'm hoping there is something like $T.table:3 available) Currently the only way I can think of to access a specific object in an array is to do something like this... {#foreach $T.table as record} {#if $T.record$iteration == 3} This is record 3! Name: {$T.record.name} {#/if} {#/for} However that seems clumsy... Any suggestions? Thanks

  • HTML wrapper div over embedded flash object cannot be "clickable" by jQuery

    - by Michael Mao
    Hi all: I've been trying to do as the client requested : redirect to campaign page then to destination page once a customer clicks on the top banner in swf format. You can check what's been done at :http://ausdcf.org If you are using Firefox, Chrome or Safari, I suspect you can reach the destination page. However, if you are using IE or Opera, I doubt it. I think to cause of such a weird problem is: The swf ojbects don't have a link to url, SO I have to hack the theme template file like this : <div id="header">'; /* * A quick and dirty way to put some swf into PHP, and rotate among them ... */ //available banners $banners = array( 'http://localhost/smf/flash/banner_fertalign_1.swf', 'http://localhost/smf/flash/banner_fertalign_2.swf', 'http://localhost/smf/flash/banner_fertalign_3.swf' ); //get random banner srand((double) microtime() * 1000000); $rand = rand(0,count($banners)-1); echo '<div id="top_banner_clickable">'; echo '<div id="top_banner_wrapper">'; echo '<object width="400" height="60">'; echo '<param name="wmode" value="transparent">'; echo '<embed wmode="transparent" src="'.$banners[$rand].'" '; echo 'width="400" height="60" type="application/x-shockwave-flash"'; echo 'pluginspage="http://www.macromedia.com/shockwave/download/index.cgi?P1_Prod_Version=ShockwaveFlash" />'; echo '</object>'; echo '</div>'; echo '</div>'; And the related jQuery code is like this: /* master.js */ $(document).ready(function() { $("#top_banner_clickable").click(function() { window.location ="http://ausdcf.org/campaign/"; }); }); I absolutely know nothing about Flash or embedded objects. I guess that's the cause of this problem. Plus, I don't know why it works with some browsers but not all... I even tried to add a z-index to the wrapper div in css like this: #top_banner_clickable { z-index : 100; } No this wouldn't do, either... Is there a way to go around this issue? Many thanks in advance.

  • Custom Alignment and Backgrounds Through Greasemonkey

    - by Jivec
    I'm trying to implement something in greasemonkey and it is giving me a fair bit of trouble as I can't get it to work. I frequently use Wolfram Alpha (http://wolframalpha.com) for a lot of things. They have recently updated the home page with a new style. There are settings that you can edit on this page (http://www.wolframalpha.com/homesettings.html) As you would expect when you clear cookies you loose these settings. What I would like to do is have a greasemonky script that sets the background to what ever I like (which will stay also regardless of the state of your cookies). It would also be cool if this background was displayed the whole way through Wolfram Alpha (ie when you make queries too eg. http://www.wolframalpha.com/input/?i=stack+overflow ) The other thing I'm trying to implement but I'm struggling is to force the results pages to be left aligned so that the browser window can be smaller. If anyone could help me with this it would be appreciated, I have tried to do it my self but I'm unsure how to get it to work.

  • Troubles with list "dropdowns" and which list item gets the dropdown

    - by Andrew
    I'm working on a project for an MMO "guild" that gives members of the guild randomly generated tasks for the game. They can "block" three tasks from being assigned. The lists will look something like this: <ul> <li class="blocked">Task that is blocked</li> <li class="blocked-open">Click to block a task</li> <li class="blocked-open">Click to block a task</li> </ul> The blocked-open class means they haven't chosen a task to block yet. The blocked task means they've already blocked a task. When they click the list item, I want this to appear: <ul class="tasks-dropdown no-display"> <li><h1>Click a Task to Block</h1></li> <ul class="task-dropdown-inner"> <?php //output all tasks foreach($tasks as $task) { echo '<li class="blocked-option"><span id="'.$task.'">'.$task.'</span></li>'; } ?> <br class="clear" /> </ul> </ul> I don't quite know how, when the user clicks the .blocked-open line-item, to show that dropdown under only the one they clicked. My jQuery looked like this before I became confused. $("li.blocked-open").click(function() { $("ul.no-display").slideToggle("900"); }); $(".blocked-option span").click(function() { var task = $(this).attr('id'); alert("You have blocked: " + task); location.reload(true); }); I tested it by putting the dropdown under a line item in the code, and it worked fine, but when I have more than one dropdown in the code, clicking on one line item toggles all the dropdowns. I'm not sure what to do. :-p.

  • SSL confirmation dialog popup auto closes in IE8 when re-accessing a JNLP file

    - by haylem
    I'm having this very annoying problem to troubleshoot and have been going at it for way too many days now, so have a go at it. The Environment We have 2 app-servers, which can be located on either the same machine or 2 different machines, and use the same signing certificate, and host 2 different web-apps. Though let's say, for the sake of our study case here, that they are on the same physical machine. So, we have: https://company.com/webapp1/ https://company.com/webapp2/ webapp1 is GWT-based rich-client which contains on one of its screens a menu with an item that is used to invoke a Java WebStart Client located on webapp2. It does so by performing a simple window.open call via this GWT call: Window.open("https://company.com/webapp2/app.jnlp", "_blank", null); Expected Behavior User merrilly goes to webapp1 User navigates to menu entry to start the WebStart app and clicks on it browser fires off a separate window/dialog which, depending on the browser and its security settings, will: request confirmation to navigate to this secure site, directly download the file, and possibly auto-execute a javaws process if there's a file association, otherwise the user can simply click on the file and start the app (or go about doing whatever it takes here). If you close the app, close the dialog, and re-click the menu entry, the same thing should happen again. Actual Behavior On Anything but God-forsaken IE 8 (Though I admit there's also all the god-forsaken pre-IE8 stuff, but the Requirements Lords being merciful we have already recently managed to make them drop these suckers. That was close. Let's hold hands and say a prayer of gratitude.) Stuff just works. JNLP gets downloaded, app executes just fine, you can close the app and re-do all the steps and it will restart happily. People rejoice. Puppies are safe and play on green hills in the sunshine. Developers can go grab a coffee and move on to more meaningful and rewarding tasks, like checking out on SO questions. Chrome doesn't want to execute the JNLP, but who cares? Customers won't get RSI from clicking a file every other week. On God-forsaken IE8 On the first visit, the dialog opens and requests confirmation for the user to continue to webapp2, though it could be unsafe (here be dragons, I tell you). The JNLP downloads and auto-opens, the app start. Your breathing is steady and slow. You close the app, close that SSL confirmation dialog, and re-click the menu entry. The dialog opens and auto-closes. Nothing starts, the file wasn't downloaded to any known location and Fiddler just reports the connection was closed. If you close IE and reach that menu item to click it again, it is now back to working correctly. Until you try again during the same session, of course. Your heart-rate goes up, you get some more coffee to make matters worse, and start looking for plain tickets online and a cheap but heavy golf-club on an online auction site to go clubbing baby polar seals to avenge your bloodthirst, as the gates to the IE team in Redmond are probably more secured than an ice block, as one would assume they get death threats often. Plus, the IE9 and IE10 teams are already hard at work fxing the crap left by their predecessors, so maybe you don't want to be too hard on them, and you don't have money to waste on a PI to track down the former devs responsible for this mess. Added Details I have come across many problems with IE8 not downloading files over SSL when it uses a no-cache header. This was indeed one of our problems, which seems to be worked out now. It downloads files fine, webapp2 uses the following headers to serve the JNLP file: response.setHeader("Cache-Control", "private, must-revalidate"); // IE8 happy response.setHeader("Pragma", "private"); // IE8 happy response.setHeader("Expires", "0"); // IE8 happy response.setHeader("Access-Control-Allow-Origin", "*"); // allow to request via cross-origin AJAX response.setContentType("application/x-java-jnlp-file"); // please exec me As you might have inferred, we get some confirmation dialog because there's something odd with the SSL certificate. Unfortunately I have no control over that. Assuming that's only temporary and for development purposes as we usually don't get our hands on the production certs. So the SSL cert is expired and doesn't specify the server. And the confirmation dialog. Wouldn't be that bad if it weren't for IE, as other browsers don't care, just ask for confirmation, and execute as expected and consistantly. Please, pretty please, help me, or I might consider sacrificial killings as an option. And I think I just found a decently prized stainless steel golf-club, so I'm right on the edge of gore. Side Notes Might actually be related to IE8 window.open SSL Certificate issue. Though it doesn't explain why the dialog would auto-close (that really is beyong me...), it could help to not have the confirmation dialog and not need the dialog at all. For instance, I was thinking that just having a simple URL in that menu instead of have it entirely managed by GWT code to invoke a Window.open would solve the problem. But I don't have control on that menu, and also I'm very curious how this could be fixed otherwise and why the hell it happens in the first place...
