• UnknownHostException again!

  - by Nitesh Panchal

  Hello, I posted one question previously and all of them answered that there is some problem with DNS but i changed my DNS to many addressed and now i have the most reliable, google DNS :- 8.8.8.8 Still i get the same UnknownHostException. What can be the problem? This is my code :- DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance(); DocumentBuilder db = dbf.newDocumentBuilder(); Document doc = db.parse("http://rss.news.yahoo.com/rss/india"); Infact if i pass address as something very common like :- http://google.com i still get the same error. Please help me :(. I have my submissions tomorrow. Thanks in advance :) EDIT : If i type the same address in my mozilla, it works great. So, i am sure that there is no DNS problem. 2nd EDIT :- I found this link http://www.ehow.com/how_4747553_fix-unknownhostexception-java-applications-ubuntu.html But when i run the command sudo apt-get install lib32nss-mdns i get package not found. Somebody even mentioned :- -Djava.net.preferIPv4Stack=true But where do i write this statement of Djava? I am using Netbeans 6.8 to run my web application

• Enable/disable virtual keyboard

  - by dr.Xis

  I'm using a virtual keyboard. I have a checkbox that controls whether the virtual keyboard is displayed or not. The thing is that I don't understand how to disable it. I try to unbind it but it doesn't work... I also tried to use namespaces and then unbind all namespaces but still the keyboard remains accessible after a click on the text box. <input class="virtualKeyboardField ui-keyboard-input ui-widget-content ui-corner-all" data-val="true" data-val-required="The User name field is required." id="loginUserName" name="UserName" type="text" value="" aria-haspopup="true" role="textbox"> <script type="text/javascript"> $(function () { //show login $("#showLogin").on({ click: function () { $("#loginFormDiv").toggle("slow"); } }); $("#cb_showVKey").on('click', CheckIsToShowKey); }); function CheckIsToShowKey(event) { //var isCheck = $("#cb_showVKey").is(':checked'); //alert("ischecked? " + isCheck); if ($("#cb_showVKey").is(':checked')) { //if checked BindKeyboards(); } else { //not checked UnBindKeyboards(); } } function bindVirtualKeyboards() { $("#loginForm").delegate(".virtualKeyboardField", "click.xpto", BindKeyboards); } function UnBindKeyboards() { $("#loginForm").undelegate(".virtualKeyboardField", "click.xpto", BindKeyboards); } function BindKeyboards() { // alert(event.currentTarget.id); //alert("xpto"); if ($("#cb_showVKey").is(':checked')) { $("#loginUserName").keyboard({ layout: 'qwerty', lockInput: true, preventPaste: true }); $("#loginUserPassword").keyboard({ layout: 'qwerty', lockInput: true, preventPaste: true }); } } $(document).ready(function () { $("#loginForm").validate(); BindKeyboards(); }); </script> Any help guys?

• Write a completely fluid HTML page (using '%' instead of 'px' for EVERY element height/width)

  - by barak manos

  I am designing my HTML pages to be completely fluid: For every element in the mark-up (HTML), I am using 'style="height:%;width:%"' (instead of 'style="height:*px;width:*px"'). This approach seems to work pretty well, except for when changing the window measurements, in which case, the web page elements change their position and end up "on top of each other". I have come up with a pretty good run-time (java-script) solution to that: var elements = document.getElementsByTagName("*"); for (var i=0; i < elements.length; i++) { if (elements[i].style.height) elements[i].style.height = elements[i].offsetHeight+"px"; if (elements[i].style.width ) elements[i].style.width = elements[i].offsetWidth +"px"; } The only problem remaining is, that if the user opens up the website by entering the URL into a non-maximized window, then the page fits that portion of the window. Then, when maximizing the window, the page remains in its previous measurements. So in essence, I have solved the initial problem (when changing the window measurements), but only when the window is initially in its maximum size. Any ideas on how to tackle this problem? (given that I would like to keep my "% page-design" as is).

• How do I use jquery to both download & delete files dynamically from servlet

  - by Adam

  Is it possible to a jquery $.get() to call a servlet and use it to both download a file or update the page without reloading the page? (Or more basically, can I download a file without reloading the page?) For example, I am using a servlet that either returns a file to download of mimetype "application/octet-stream", or returns text to be update in the page of type "text/html". I can write a form with a submit, but then it reloads the page, so I've been trying to use $.get()... but the download doesn't work. <script type="text/javascript"> jQuery(document).ready(function(){ $("#handleFileOptions button").button(); }); function handleFilesSubmit(requestType) { $.get('FileServlet', {filename: $('#radioFileList input:radio:checked').button("widget").text(), requestType: requestType}, function(data){ ...?... }); } </script> In the html: <div id = "handleFiles"> <div id ="radioFileList"> <div id="radioFileList"> <input value="file0.txt" type="radio" id="fileitem0><label for="fileitem0">file0.txt</label> <input value="file1.txt" type="radio" id="fileitem1><label for="fileitem0">file1.txt</label> </div> </div> <div id="handleFileOptions"> <button id="handleFileOption0" onclick="handleFilesSubmit('Download')">Download</button> <button id="handleFileOption1" onclick="handleFilesSubmit('Delete')">Delete</button> </div> </div>

• Issue creating side-by-side slideshows with jQuery

  - by JShweky

  I'm trying to create a site with 2 slideshows. I've tweaked and re-tweaked the JS and Jquery numerous times. Sometimes one slideshow works perfectly and the other cycles between one picture, other times both work but are out of sync, or the fadeIn doesn't seem to be applied to the second slideshow, or in some variations one slideshow stays frozen on the initial image and just remains static. Anyway, I created a JS Fiddle (link at bottom) and apparently my code is at least free of typos. JS is below, the rest is on the JS Fiddle. Any help would be greatly appreciated. $(document).ready(function () { $(".slider #1").fadeIn(1000); $(".slider #1").delay(2000).fadeOut(1000); var sc = $(".slider img").size(); var count = 2; setInterval(function () { $(".slider #" + count).fadeIn(1000); $(".slider #" + count).delay(2000).fadeOut(1000); if (count === sc) { count = 1; } else { count++; } }, 3500); $(".sliderTwo #7").fadeIn(1000); $(".sliderTwo #7").delay(2000).fadeOut(1000); var sc2 = 12; var count2 = 7; setInterval(function () { $(".sliderTwo #" + count2).fadeIn(1000); $(".sliderTwo #" + count2).delay(2000).fadeOut(1000); if (count2 === sc2) { count2 = 7; } else { count2++; } }, 3500); }); http://jsfiddle.net/gg4PL/

• HTML + Button with text and image on it.

  - by lucky

  Hello, I have a problem in creating a Button with text and image on it. <td> <button type="submit" name="report" value="Report" <?php if($tab == 'Excel') echo "id=\"tab_inactive\""; else echo "id=\"tab_active\"" ; ?>> <img src="images/report.gif" alt="Report"/>Report </button> <button type="submit" name="excel" value="Excel" <?php if($tab == 'Excel' ) echo "id=\"tab_active\""; else echo "id=\"tab_inactive\"" ; ?>> <img src="images/Excel.gif" alt="Excel" width="16" height="16" /> Excel </button> </td> Here $tab is $tab = strlen(trim($_POST[excel]))>0 ? $_POST[excel] : $_POST[report]; I tried this way, but this is behaving so strangely. On click the button:- The submit function is working properly in firefox, but not in IE. Instead of submitting the value(in this example values are 'Report' and 'Excel'), indeed it is submitting the label of the button. That is if i am checking the value of array PRINT_R($_POST). The value of it is Array ( [report] =>(Icon that i used) Report [excel] => (Icon that i used) Excel [frm_analysis] => [to_analysis] => ) Here i have more than 1 button, then all the labels are submitted eventhough one of them is pressed. i dont how to capture which button is pressed. I even tried changing button type=button and onclick="document.formname.submit()" Even this is resulting in the same. Can you please help me to solve this.

• Position footer to bottom of window or page, whichever is larger

  - by BenM

  I am currently working on a site that requires a footer to be placed either at the bottom of the window, or the bottom of the page content, whichever is lower. I have tried using the height: 100% method, but this causes a problem. I also have a position: fixed header, and some padding on my content (defined in pixels). Also, the height of the content may change after the page has loaded (use of accordions, etc.), so I wonder if there's a pure CSS way to position the footer to either the bottom of the window, or the bottom of the document, while still allowing pixel padding and so forth. Here's an outlined structure of the HTML: <header></header> <div class="content"> <footer></footer> </div> I have also put together a Fiddle to demonstrate how the CSS works at the moment: http://jsfiddle.net/LY6Zs/. I am unfortunately unable to change the HTML structure (i.e. breaking out the footer element from .content.

• Javascript, problem with binding an event to a div-tag

  - by Patrick

  Hello, i am trying to bind an event to a dynamically created div. function GameField(playerNumber) { this.fields = new Array(); this.player = playerNumber; this.isPlayerActive = false; this.currentRound = 0; } GameField.prototype.InitField = function(fieldNumber) { var newField = document.createElement("div"); if (fieldNumber == 0 || fieldNumber == 6 || fieldNumber == 8 || fieldNumber == 17) newField.className = 'gameCellSmall borderFull gameText gameTextAlign'; else newField.className = 'gameCellSmall borderWithoutTop gameText gameTextAlign'; newField.onclick = function() { this.DivClick('a'); } this.fields[fieldNumber] = newField; return newField; } GameField.prototype.DivClick = function(fieldNumber) { alert('Nummer: ' + fieldNumber); } Everything works perfectly, but when you click on one of the created divs, i end up with the following error message: Error: Object doesn't support this property or method. If i replace the onclick function with this, then it works: newField.onclick = function() { alert('Nummer: ' + fieldNumber); } How can i get the onclick event to fire my DivClick function instead?

• jQuery date calculator - show/hide IMG

  - by utopicam

  I have a problem with the following code. I tried changing many things (symbols, classes, imgs in the code) but this is killing me and I have no idea how to fix it. Sorry it's so specific, when solved I'll change the title to something more useful. I have two images. My jquery has to calculate the day and show one image or the other depending on that (using a class with display:none). My month has 24 days (it's a xmas thing). This is what I have so far: <script type="text/javascript"> $(document).ready(function(){ var currentTime = new Date() var day = currentTime.getDate(); if (day > 24){ day = 1; } $(".calDate").each(function(){ var curDate = $(this).attr("date"); if (curDate < day){ $(this).addClass("xMasPast"); } else if(curDate==day){ $(this).addClass("xMasActive"); } else { $(this).addClass("xMasInactive"); } }); $(".calDate2").each(function(){ var curDate = $(this).attr("date"); if (curDate > day){ $(this).addClass("xMasInactive"); } else if(curDate==day){ $(this).addClass("xMasActive"); } else { $(this).addClass("xMasActive"); } }); }); </script> But it's showing all the images. What am I missing? (any ideas on making the code simpler are more than welcomed). Thanks for your help! Update: simplified HTML <div><img src="day21.png" which="21"/></a></div> <img id="bola21" class="calDate2" src="day21.png"/>

• jQuery, Ajax & PHP submit multiple forms dilemma

  - by user557563

  This is a very simple form that I have found on the web (as I am a jQuery beginner). <!-- this is my jquery --> <script> $(document).ready(function(){ $("form#submit_wall").submit(function() { var message_wall = $('#message_wall').attr('value'); var id = $('#id').attr('value'); $.ajax({ type: "POST", url: "index.php?leht=pildid", data:"message_wall="+ message_wall + "&id="+ id, cache: false, success: function(){ $("ul#wall").prepend(""+message_wall+"", ""+id+""); $("ul#wall li:first").fadeIn(); alert("Thank you for your comment!"); } }); return false; }); }); </script> <!-- this is my HTML+PHP --> some PHP ... while($row_pilt = mysql_fetch_assoc($select_pilt)){ print <form id="submit_wall"> <label for="message_wall">Share your message on the Wall</label> <input type="text" id="message_wall" /> <input type="hidden" id="id" value="'.(int)$row_pilt['id'].'"> <button type="submit">Post to wall</button> </form> and down below is my PHP script that writes to mySQL. It is a pretty straight forward script. However, it is getting little complicated when I submit it. Since I have more than one form on my page (per WHILE PHP LOOP), thus when I submit - only the FIRST form gets submitted. Furthermore, any other subsequent forms that I submit - data is being copied from the first form. Is there any jQuery functions that clear the data? - or is there a better solution. Thanks, Nick

• How can I [simply] consume JSON Data to display to the page

  - by Atomiton

  I usually use JSON with jQuery to just return a string with html. However, I want to start to use Javascript objects in my code. What's the simplest way to get started using json objects on my page? Here's a sample Ajax call ( after $(document).ready( { ... }) of course: $('#btn').click(function(event) { event.preventDefault(); var out = $('#result'); $.ajax({ url: "CustomerServices.asmx/GetCustomersByInvoiceCount", success: function(msg) { // // Iterate through the json results and spit them out to a page? // }, data: "{ 'invoiceCount' : 100 }" }); }); My WebMethod: [WebMethod(Description="Gets customers with more than n invoices")] public List<Customer> GetCustomersByInvoiceCount(int? invoiceCount) { using (dbDataContext db = new dbDataContext()) { return db.Customers.Where(c => c.InvoiceCount >= invoiceCount); } } What gets returned: {"d":[{"__type":"Customer","Account":"1116317","Name":"SOME COMPANY","Address":"UNit 1 , 392 JOHN ST. ","LastTransaction":"\/Date(1268294400000)\/","HighestBalance":13922.34},{"__type":"Customer","Account":"1116318","Name":"ANOTHER COMPANY","Address":"UNIT #345 , 392 JOHN ST. ","LastTransaction":"\/Date(1265097600000)\/","HighestBalance":549.42}]} What I'd LIKE to know, is what are people generally doing with this returned json? Do you iterate through the properties and create an html table on the fly? Is there way to "bind" JSON data using a javascript version of reflection ( something like the .Net GridView Control ) Do you throw this returned data into a Javascript Object and then do something with it? An example of what I want to achieve is to have an plain ol' html page ( on a mobile device )with a list of a Salesperson's Customers. When one of those customers are clicked, the customer id gets sent to a webservice which retrieves the customer details that are relevant to a sales person. I know the SO talent pool is quite deep so I figured you all here would be able to guide in the right direction and give me a few ideas on the best way to approach this.

• navigation li to create <span></span> around text via jquery

  - by MikesEpitaphSays

  I've been trying all day and reading a few things, but for some reason my code isn't working right What i'm trying to achieve is this: When i create an un ordered list in my index page - I want my jquery to automatically add around the text in the anchor. So i want it to look like this <li><a href="index.htm"><span>Home</span></a></li> while I am only adding: <li><a href="index.htm">Home</a></li> I want to do this because i have a LOT of list items and instead of writing when i'm adding pages it makes the most sense to save some time in the long run and create a loop that will handle that anytime i add one. This is What i have so far (sorry if it looks ugly): $('document').ready(function () { var begSpan = "<span>"; var endSpan = "</span>"; $('p').each(function () { $(this) prepend(begSpan); }).append(endSpan); }); How can i get that to auto create span tags for me

• What's wrong (or right) with this JS Object Pattern?

  - by unsane1

  Here's an example of the pattern I'm using in my javascript objects these days (this example relies on jQuery). http://pastie.org/private/ryn0m1gnjsxdos9onsyxg It works for me reasonably well, but I'm guessing there's something wrong, or at least sub-optimal about it, I'm just curious to get people's opinions. Here's a smaller, inline example of it: sample = function(attach) { // set internal reference to self var self = this; // public variable(s) self.iAmPublic = true; // private variable(s) var debug = false; var host = attach; var pane = { element: false, display: false } // public function(s) self.show = function() { if (!pane.display) { position(); $(pane.element).show('fast'); pane.display = true; } } self.hide = function() { if (pane.display) { $(pane.element).hide('fast'); pane.display = false; } } // private function(s) function init () { // do whatever stuff is needed on instantiation of this object // like perhaps positioning a hidden div pane.element = document.createElement('div'); return self; } function position() { var h = { 'h': $(host).outerHeight(), 'w': $(host).outerWidth(), 'pos': $(host).offset() }; var p = { 'w': $(pane.element).outerWidth() }; $(pane.element).css({ top: h.pos.top + (h.h-1), left: h.pos.left + ((h.w - p.w) / 2) }); } function log () { if (debug) { console.log(arguments); } } // on-instantiation let's set ourselves up return init(); } I'm really curious to get people's thoughts on this.

• What goes into the "Controller" in "MVC"?

  - by P72endragon

  I think I understand the basic concepts of MVC - the Model contains the data and behaviour of the application, the View is responsible for displaying it to the user and the Controller deals with user input. What I'm uncertain about is exactly what goes in the Controller. Lets say for example I have a fairly simple application (I'm specifically thinking Java, but I suppose the same principles apply elsewhere). I organise my code into 3 packages called app.model, app.view and app.controller. Within the app.model package, I have a few classes that reflect the actual behaviour of the application. These extends Observable and use setChanged() and notifyObservers() to trigger the views to update when appropriate. The app.view package has a class (or several classes for different types of display) that uses javax.swing components to handle the display. Some of these components need to feed back into the Model. If I understand correctly, the View shouldn't have anything to do with the feedback - that should be dealt with by the Controller. So what do I actually put in the Controller? Do I put the public void actionPerformed(ActionEvent e) in the View with just a call to a method in the Controller? If so, should any validation etc be done in the Controller? If so, how do I feedback error messages back to the View - should that go through the Model again, or should the Controller just send it straight back to View? If the validation is done in the View, what do I put in the Controller? Sorry for the long question, I just wanted to document my understanding of the process and hopefully someone can clarify this issue for me!

• Get height of DIV and it's content with JQuery

  - by user1012403

  I have a div which contains several elements: <div class="menuItem designMenu" id="dMenu"> <ul class="menuList menu"> <li class="menuHeader">Design</li> <li class="projectHeader">Mother</li> <li class="projectBody">Some text here</li> <li class="more">More</li> </ul> </div> I need to get the height of the dMenu items that I can animate it upwards, including all the content inside. My Javascript currently: var designHeight = $("#dMenu").height(); Returns nothing. I've tried offsetHeight, scrollHeight, and everything else Google turns up. I'm running the JQuery at the end of the body, inside a document ready function. The reason to get the height to animate, instead of doing it manually, is that a: I'd like to learn how and b: I don't yet know how many items will be int he div. Thanks.

• I can't find the homepage for my ASP.NET MVC site :(

  - by Pure.Krome

  Hi folks, really simple question here. when I remove the default route, I returns an empty page to the browser :- routes.MapRoute( "Default", // Route name "{controller}/{action}/{id}", // URL with parameters new { controller = "Home", action = "Index", id = UrlParameter.Optional } ); Now before everyone starts shouting "that's because that's the default route to access all action methods, etc.." .. i know that. My question is - what code / routes does the default framework try and call .. which makes that Default Route get used/kick in? Why? I don't wish to make that my default route regex (don't ask why - this is some R&D) but I still need the main home page .. ie. Home/Index . If i try and just add that route, it doesn't get called and an empty page is returned. So -- what does the framework try and call when a user doesn't provide any urls? It's like there's some secret default document stuff set up? Cheers :)

• Modifying html of dom element that was created after page loaded

  - by Ben321

  I have two separate AJAX calls. One that gets a list of items from a txt file and creates an HTML table out of them and one that talks to a database to find how much each item costs and then lists this in the corresponding table cell for each item (I know this may sound like a strange approach, but it's a good option in our case...). The issue is that the price is not getting written to the table since the table is created (or to be precise, the rows of the table are created) after the page loads. I'm not sure how to fix this. $(document).ready(function() { makeItemTable(); listPrices(); ... }); function makeItemTable() { $.ajax({ url: 'products.php', type: 'GET' }) .done(function(response) { $('.price-table > tbody').html(response); }) } function listPrices() { .ajax({ url: 'prices.php', type: 'GET' }) .done(function(response) { priceData = $.parseJSON(response); $('.price-table tr').each(function() { var item = $(this).find('td:nth-child(1)').text(); if (priceData[item]) { var price = priceData[item]; $(this).find('td:nth-child(2)').text(price); } }) }

The code the creation of the forms is: <tr> <td class='items' width='80%' align='center' valign='top'><?PHP echo $itemstore->itemname;?> </td> <td width="20%"> Price:<?PHP echo $itemstore->newprice;?> <form method="post"> <input type='text' id='amount-<?PHP echo $row;?>)' /> <input name="itembid" type="button" onclick="pbuy(<?PHP echo $row;?>)" value="Buy" /></form></td> </tr> If I hardcode the amount in the ajax function it all runs fine like it should.

• Google Chrome && (cache || memory leaks).

  - by Alexey Ogarkov

  Hello All, I have a big problem with Google Chrome and its memory. My app is displaying to user several image charts and reloads them every 10s. In the interval i have code like that var image = new Image(); var src = 'myurl/image'+new Date().getTime(); image.onload = function() { document.getElementById('myimage').src = src; image.onload = image.onabort = image.onerror = null; } image.src = src; So i have no memory leaks in Firefox and IE. Here the response headers for images Server Apache-Coyote/1.1 Vary * Cache-Control no-store (// I try no-cache, must-revalidate and so on here) Content-Type image/png Content-Length 11131 Date Mon, 31 May 2010 14:00:28 GMT Vary * taken from here In about:cache page there is no my cached images. If i enable purge-memory-button for chrome (--purge-memory-button parameter) it`s not help. Images is in PNG24. So i think that the problem is not in cache. May be Google Chrome is not releasing memory for old images. Please help. Any suggestions. Thanks.

• "The breakpoint will not currently be hit" error while debugging a mixed mode application (c# and unmanaged c++)

  - by user1678403

  While debugging a mixed mode application in VS2010, the breakpoint set on a line of code contained in an unmanaged c++ dll source file (called from a managed c# wrapper class) shows the infamous "The breakpoint will not currently be hit. No symbols have been loaded for this document" info message when hovering the mouse over the breakpoint on the line in question. The breakpoint itself is a red circle with a yellow info triangle instead of the usual solid red orb. Of course, the breakpoint isn't hit when the debugger is executed. Most answers I've found for this warning indicate the breakpoint hasn't been set properly, or that the expected dll is not being loaded, or that the associated pdb file is not located in the correct location, etc. etc. This is not the problem. The application does load and execute the referenced dll correctly. I've verified that the correct pdb file, with the same file date as its dll, is located in the executable's working directory along with the target dll itself. The debugger simply doesn't load the symbols for the dll, and the dll doesn't show in the Modules list. None of the solutions I've found online work for this problem. The dll doesn't show in the modules list available from 'Debug-Windows-Modules' menu selection... even though it is, in fact, loaded. Breakpoints set in the wrapper class work correctly. Deleting the bin and obj directories, cleaning and rebuilding the solution also doesn't help.

• Pass/Access Object Attributes to/from another Class

  - by Namuna

  Issue: Unable to access parent object attributes Verification.pm: (Parent class) package Verification; use Verification::Proid; sub Proid { my $self = shift; print Dumper($self); my $result = Verification::Proid->validate($self); return $result; } Dumper result $VAR1 = bless( { 'event_name' => 'validate', 'Verification_Type' => 'Proid', 'Verification_Value' => 'ecmetric', 'xml_request' => bless( do{\(my $o = 148410616)}, 'XML::LibXML::Document' ), 'Verification_Options' => [ { '2' => 'UNIX' } ], 'Verification_ID' => '3' }, 'Verification' ); Proid.pm: (Child class) package Verification::Proid; our @ISA = qw(Verification); sub validate { my $self = shift; print Dumper($self); my $result; foreach my $validation_type ( @$self->{Verification_Options} ) { do stuff... } } Dumper result $VAR1 = 'Verification::Proid'; What am I doing wrong that the child class isn't properly getting all the attributes from the object passed to it? Thank you!
