  • How to do it more efficiently?

    - by David Maricone
    Let's imagine we should get some data... var data = []; //some code omitted that might fill in the data (though might not) Then we need to do something with the data. And my question is how to do it more effectively. Like so?: if (data.length) { for (var i = 0; i < data.length; i++) { //iterate over the data and do something to it } } Or just like so?: for (var i = 0; i < data.length; i++) { //iterate over the data and do something to it } The point is whether to check the length before iterating or not?

  • cross domain DOM access and manipulation in Java ?

    - by gaqer
    In my Java app, how can I incorporate the browser (which loads and renders URLs) in Swing and access it's DOM and manipulate HTML ? How can you embed such browser in a Rich Internet Application and access it's DOM ? More specifically, Vaadin ? Is there a HTTP proxy class that can load an external URL, and render it to the user ? This was what I was doing on LAMP stack....but I want to switch to Vaadin or some Java web framework where I can just use Java to do everything from server-side to client-side logic design, so I can focus more on application logic. (aka looking for developer friendly frameworks like Vaadin). Thank you and have a great weekend !

  • Uploading multiple files asynchronously by blueimp jquery-fileupload

    - by Ryo
    I'm using jQuery File Upload library (http://github.com/blueimp/jQuery-File-Upload), and I've been stuck figuring out how to use the library satisfying the following conditions. The page has multiple file input fields surrounded by a form tag. Users can attach multiple files to each input field All files are sent to a server when the button is clicked, not when files are attached to the input fields. Upload is done asynchronously Say the page has 3 input fields with their name attributes being "file1[]", "file2[]" and "file3[]", the request payload should be like {file1: [ array of files on file1[] ], file2: [ array of files on file2[] ], ...} Here's jsFiddle, it's behaving weird so far in that it sends post request twice and the first one is cancelled. http://jsfiddle.net/BAQtG/24/ The core part of js code looks like this. $(document).ready(function(){ var filesList = [] var elem = $("form") file_upload = elem.fileupload({ formData:{extra:1}, autoUpload: false, fileInput: $("input:file"), }).on("fileuploadadd", function(e, data){ filesList.push(data.files[0]) }); $("button").click(function(){ file_upload.fileupload('send', {files:filesList} ) }) }) Anybody have idea how to get this to work? Updates Now thanks to @CBroe 's comment, the issue that request is sent twice is fixed. However the keys of request parameter is not correctly set. Here's updated jsFiddle. http://jsfiddle.net/BAQtG/27/

  • In jQuery datepicker beforeShowDay if fails

    - by michalzuber
    HI. I'm having problem to highlight more days. Somehow the if statement in beforeShowDay isn't true when it should be :( dateString typeof is string and an example is available in the screenshot at http://mikaelz.host.sk/datepicker.png Pasted code: var dates = new Array(); function addDate(date) {if (jQuery.inArray(date, dates) < 0) dates.push(date);} function removeDate(index) {dates.splice(index, 1);} function addOrRemoveDate(date) { var index = jQuery.inArray(date, dates); if (index >= 0) removeDate(index); else addDate(date); } function padNumber(number) { var ret = new String(number); if (ret.length == 1) ret = "0" + ret; return ret; } jQuery(document).ready(function(){ jQuery("#pick-date").datepicker({ onSelect: function(dateText, inst) { addOrRemoveDate(dateText); }, beforeShowDay: function (date){ var year = date.getFullYear(); var month = padNumber(date.getMonth()); var day = padNumber(date.getDate()); var dateString = day + "." + month + "." + year; if (dates.indexOf(dateString) >= 0) { return [true,"ui-state-highlight"]; } return [true, ""]; } }); }); Big thanks for any good ideas what could be wrong.

  • Uncaught SyntaxError: Unexpected token var

    - by Bob R
    I have an error Uncaught SyntaxError: Unexpected token var displayed between (1) and (2) its a very odd error and it doesn't make sense at all. if ($hiddenimage.length==0){ //if this is the first time moving over or clicking on the anchor link var $hiddenimage=$('<img src="'+this.href+'" />').appendTo($hiddenimagediv) //populate hidden div with enlarged image $hiddenimage.bind('loadevt', function(e){ //when enlarged image has fully loaded loadarea.empty().append($.thumbnailviewer2.buildimage($, $anchor, s, options) (1) - var $targetimage=$.thumbnailviewer2.buildimage($, $anchor, s, options) //create reference actual enlarged image (2) - $loadarea.empty().append($targetimage) //show enlarged image $.thumbnailviewer2.showimage($targetimage, s) })

  • Is it possible to wrap an asynchronous event and its callback in a function that returns a boolean?

    - by Rob Flaherty
    I'm trying to write a simple test that creates an image element, checks the image attributes, and then returns true/false. The problem is that using the onload event makes the test asynchronous. On it own this isn't a problem (using a callback as I've done in the code below is easy), but what I can't figure out is how to encapsulate this into a single function that returns a boolean. I've tried various combinations of closures, recursion, and self-executing functions but have had no luck. So my question: am I being dense and overlooking something simple, or is this in fact not possible, because, no matter what, I'm still trying to wrap an asynchronous function in synchronous expectations? Here's the code: var supportsImage = function(callback) { var img = new Image(); img.onload = function() { //Check attributes and pass true or false to callback callback(true); }; img.src = 'data:image/gif;base64,R0lGODlhAQABAAD/ACwAAAAAAQABAAACADs='; }; supportsImage(function(status){ console.log(status); }); To be clear, what I want is to be able to wrap this in something such that it can be used like: if (supportsImage) { //Do some crazy stuff } Thanks! (Btw, I know there are a ton of SO questions regarding confusion about synchronous vs. asynchronous. Apologies if this can be reduced to something previously answered.)

  • In SVG is there a way to grab a shape anywhere when it has fill = "none"

    - by Shaunwithanau
    I have a series of shapes that I want the user to be able click anywhere on the shape to pick up as part of a drag and drop feature. All of these shapes are bounded by a rectangle. For example: <g id="shape1" fill="none" stroke="black"> <rect x="0" y="0" width="100" height="100"/> <circle cx="50" cy="50" r="50"/> </g> <g id="shape2" fill="none" stroke="black"> <rect x="0" y="0" width="100" height="100"/> <line x1="0" y1="0" x2="50" y2="100"/> <line x1="100" y1="0" x2="50" y2="100"/> </g> I already have all of the drag and drop parts working, the problem is all of these shapes have to have fill="none" so you can see anything that may be underneath of them. This means that even though they are bounded by the rectangle, at the moment users have to physically click on one of the lines in order to pick it up instead of being able to click anywhere on the shape like I want. My original idea was to use fill="white" and then set opacity="0" or some really low value but this applies to the stroke as well so this didn't work out. Any ideas on how I can get this working?

  • Is there a way to do this with basic JS DOM?

    - by Thomas
    I need to apply/remove to an input field according to a user's selection in a separate drop down form - but I can't figure out how to target the input's class. I need to add/remove the 'pageRequired' class from this input: <input type="text" title="Company Required" name="customfields-tf-2-tf" class="inputclass pageRequired textInput" id="customfields-tf-2-tf" /> When the user selects one of two options from a drop down field. For example: <select class="dropdown" name="customfields-s-1-s" id="customfields-s-1-s" > <option value="Owner"<?php if(in_array("Owner",$temp_values)) { ?> selected='selected'<?php } ?>> Owner</option> <option value="Broker"<?php if(in_array("Broker",$temp_values)) { ?> selected='selected'<?php } ?>> Broker</option> </select> If the user selects broker than I want to add the pageRequired class to the first input field and remove it if the user selects Owner.

  • How can I make my Video play as soon as the page loads

    - by bill
    im lost here, need some help for something probably very simple: I have embedded a swf object to play an flv file. i want the video to play as soon as the page loads rather than requiring the viewer/user to have to click the play button to see the video. I'm not sure if it is the swf file, the script or the javascipt file that has to be edited, and with what code. thanks

  • Step by Step validation with jquery validation plugin

    - by Alex
    I know its been asked many times already but no one could come up with solution so far. The idea is to have one form separated into few steps and validate each step on next click of the button. I know jquery validation plugin is offering quite complicated way of doing it with accordion but can anyone come up with a simple solution something like var stepOne = { rules: { fieldname1: "required", fieldname2: "required", } } $("form").validate(stepOne); //onclick hope someone could suggest the best way of doing it. Thanks.

  • Find the exact height and width of the viewport in a cross-browser way (no Prototype/jQuery)

    - by lyoshenka
    I'm trying to find the exact height and width of a browser's viewport, but I suspect that either Mozilla or IE is giving me the wrong number. Here's my method for height: var viewportHeight = window.innerHeight || document.documentElement.clientHeight || document.body.clientHeight; I haven't started on width yet but I'm guessing it's going to be something similar. Is there a more correct way of getting this information? Ideally, I'd like the solution to work with Safari/Chrome/other browsers as well.

  • Backbone.js - Getting JSON back from url

    - by Brian
    While trying to learn Backbone.js, I've been trying to grab the content of a JSON file using the following code: (function($){ var MyModel = Backbone.Model.extend(); var MyCollection = Backbone.Collection.extend({ model : MyModel, url: '/backbone/data.json', parse: function(response) { console.log(response); return response; } }); var stuff = new MyCollection; console.log(stuff.fetch()); console.log(stuff.toJSON()); })(jQuery) 'stuff.fetch()' returns the entire object (with the data I'm after in responseText), 'stuff.toJSON' returns nothing ([]), but the console in the parse method is returning exactly what I want (the json object of my data). I feel like I'm missing something obvious here, but I just can't seem to figure it out why I can't get the right data out. Could someone point me in the right direction or show me what I'm doing wrong here? Am I using a model for the wrong thing?

  • Printing saved HTML to jsp keeps getting corrupted

    - by JWL
    I have a JAVA object where I save a HTML string value I call message. The saved data looks like the below, You have received a new <a href='' onclick='return popupRentalView('5282053859835904');'>Rental Request 5282053859835904</a>. Please view your open orders. But when printed to the JSP file and displayed at runtime using <%=pm.getMessage()%> or <%out.print(pm.getMessage());%> The actual html code comes out all messed up, You have received a new <a 5282053859835904');'="" onclick="return popupRentalView(" href="">Rental Request 5282053859835904</a> . Please view your open orders. Any thoughts on why the displayed string does not match the saved string? JAVA code for saving is note.setMessage("You have received a new <a href=\"\" onclick='return popupRentalView('" + requestId + "');'> Rental Request " + requestId + "</a>. Please view your open orders.");

  • Is there anything on a local network or desktop environment that could effect JScript execution?

    - by uku
    I know this sounds odd. The JS on my project functions perfectly, except when the web site is accessed using computers at one specific company. To make things even more difficult, the JS fails only about 50% of the time when run from that company. The JS failure occurs with FireFox, Chrome, and IE. I have tested this myself using FF and Chrome on a thumb drive. The browsers on my thumb always display my project site perfectly, except when run from a computer on said company's network where they fail at the same rate as the installed browsers. My JS is using jQuery and making some Ajax calls. The Ajax calls are where the failure is occurring. To diagnose the problem I created a logging function for my Ajax calls and recorded success and failure. Over a one month period, there were only a handful of failures (about 1%) from all access points other than this company. Oddly enough, the Ajax calls in the logging function are not failing. There is nothing exotic there - Just Win XP SP3. I have never noticed any other unusual behavior from their network. The company is a division of a mega ISP and is on their corporate network. Any other suggestions for troubleshooting would be welcome.

  • Prevent backspace button from navigating back in Sharepoint 2010 and IE

    - by Machinegon
    as a user requirement I have to disable the backspace button from navigating back in the history. I made the following piece of code //Bind back nutton to prevent escaping the page with backspace $j(document).unbind('keydown').bind('keydown', function (event) { var doPrevent = false; if (event.keyCode === 8) { if(event.target == document.body){ if(event.preventDefault()){ event.preventDefault(); } event.stopEvent(); event.returnValue = false; } } }); This is working perfectly in all the browsers except IE8/7. I cannot bind the input types as exceptions because the content editor in sharepoint allows to modify the text in div or paragraph elements etc. The solution is not working in IE8 because the event.target returns the element that is on mouseover when there's no controls that has the focus. All tips will be appreciated. Thanks!!

  • Sencha 2 : Sync models with hasMany associations in LocalStorage

    - by Alytrem
    After hours and hours trying to do this, I need your help. I have to models : Project and Task. A project hasMany tasks and a task belong to a project. Everyting works well if you don't use a store to save these models. I want to save both tasks and projects in two stores (TaskStore and ProjectStore). These stores use a LocalStorage proxy. I tried many things, and the most logical is : Ext.define('MyApp.model.Task', { extend: 'Ext.data.Model', config: { fields: [ { name: 'name', type: 'string' }, { dateFormat: 'd/m/Y g:i', name: 'start', type: 'date' }, { dateFormat: 'd/m/Y g:i', name: 'end', type: 'date' }, { name: 'status', type: 'string' } ], belongsTo: { model: 'MyApp.model.Project' } } }); Ext.define('MyApp.model.Project', { extend: 'Ext.data.Model', alias: 'model.Project', config: { hasMany: { associationKey: 'tasks', model: 'MyApp.model.Task', autoLoad: true, foreignKey: 'project_id', name: 'tasks', store: {storeId: "TaskStore"} }, fields: [ { name: 'name', type: 'string' }, { dateFormat: 'd/m/Y', name: 'start', type: 'date' }, { dateFormat: 'd/m/Y', name: 'end', type: 'date' } ] } }); This is my "main" : var project = Ext.create("MyApp.model.Project", {name: "mojo", start: "17/03/2011", end: "17/03/2012", status: "termine"}); var task = Ext.create("MyApp.model.Task", {name: "todo", start: "17/03/2011 10:00", end: "17/03/2012 19:00", status: "termine"}); project.tasks().add(task); Ext.getStore("ProjectStore").add(project); The project is added to the store, but task is not. Why ?!

  • Browser Issue: Charts are not rendered on IE8

    - by Rachel
    We have inhouse library which uses canvas for displaying charts in my application. And dojo as scripting language.Everything is fine, but my charts are not appearing in IE8. I google about this, and found that there is some VML issue in IE8. I found this: var printChart = function(time, freq){ if (!document.namespaces['g_vml_']) { document.namespaces.add('g_vml_', 'urn:schemas-microsoft-com:vml', '#default#VML'); } if (!document.namespaces['g_o_']) { document.namespaces.add('g_o_', 'urn:schemas-microsoft-com:office:office', '#default#VML'); } if (freq === undefined) { this.freq = "1mi"; } if (time === undefined) { this.time = "1dy"; } self.reload(); } Now I was trying to add this in my DOJO code and that is creating problem. As when I do document.namespace I get firebug error 'document.namespaces is undefined'. Q: How can we fix this, are the any better alternative approaches for the same, basic problem am having is browser related, charts are rendered properly on other browsers but not on IE8, any suggestions ? Update: What are ways to deal with such cross browser issue ?

    I am experimenting with html5 and I have a little image dropdown, the user selects and image and it draws it to the canvas using drawImage(); I can't seem to figure out how to add an event listener to the newly drawn image on the canvas. I have tried putting it in a variable like so: var newImg = ctx.drawImage(myImage, 200, 200); and then adding an eventlistener to that, but it doesn't seem to work. newImg.addEventListener('mousedown', onImgClick, false); What is the correct way to do this.
