HTML5 Local Storage of audio element source - is it possible?

- by andrewdotcom

Hi stackoverflow experts I've been experimenting with the audio and local storage features of html5 of late and have run into something that has me stumped. I'd like to be able to cache or store the source of the audio element locally to enable speedier and offline playback. The problem is I can't see how this is possible with the current implementation. I have tried the following using webkit: Creating a manifest file to set up local caching but the audio file appears not to be a cacheable item maybe due to the way it is stream or something I have also attempted to use javascript to put an audio object into local storage but the size of the mp3 makes this impossible due to memory issues (i think). I have tried to use the data uri and base64 to use the html as a audio transport that can be cached but again the filesize makes this prohibitive. Also the audio element does not seem to like this in webkit (works fine in mozilla) I have tried several methods of putting the data into the local database store. Again suffering the same issues as the other cases. I'd love to hear any other ideas anyone may have as to how I could achieve my goal of offline playback using caching/local storage in webkit.

Determining unknown content-types with the Html5 file api

- by Jesse

I'm working through a small file upload script (learning experience) and I noticed that when selecting microsoft office related files (.doc or .docx for example) the file objects do not have a type specified: For .doc files I had expected the type to be "application/msword" and along the same train of thought .docx to be "application/vnd.openxmlformats-officedocument.wordprocessingml.document". In the cases when the type cannot be determined is the correct course of action to look at the file extension and match that to the "expected" content / mime type? Sample script: <div id="fileUpload"> <input type="file" id="fileElem" style="display:none;" onchange="handleFiles(this.files)"/> <a href="#" id="fileSelect">Select some files</a> </div> <script type="text/javascript"> var fileSelect = document.getElementById("fileSelect"), fileElem = document.getElementById("fileElem"); fileSelect.addEventListener("click", function (e) { if (fileElem) { fileElem.click(); } e.preventDefault(); }, false); function handleFiles(files) { console.log(files); } </script>

Perl Cookie not working

- by grosseskino

Hi! I already spent all day looking for an answer for this: I am using Perl with LWP::UserAgent and HTTP::Cookies. My problem is that I can't get past an cookie-base age-check. In Perl I use this code: my $browser = LWP::UserAgent->new; my $resp = $browser->get( $url, 'User-Agent' => 'MySpider/1.0' ); #Cookie Setup my $cookies = HTTP::Cookies->new(); $cookies->set_cookie(1,'age_check', '1','/','.example.com/', 80, ,0,3354512128, 0); $browser->cookie_jar($cookies); The Site is setting the Cookie with JavaScript function saveSplash(domain) { var expDate = new Date(); expDate.setTime(expDate.getTime()+(1*24*3600*1000)); setCookie("age_check", 1, expDate, '/', domain); setCookie("screen_width", getScreenWidth(), expDate, '/', domain); } This is the Cookie saved by my browser: age_check 1 example.com/ 1088 3354512128 30140182 2646218624 30139981 Any idea what I am doing wrong? Thanks in advance guys!

I'm trying to update an image in a parent window with clickable links in a child window. I've preloaded the images in the parent window with one javascript file. "scriptss.js" My problem is I need to access the preloaded images of the parent window with the childscript "scriptremote.js" Thanks again for all the JS Help! The JS (scriptss.js) var newWindow = null; window.onload = init; var i = 0; image_object = new Image(); myImages = new Array(); // declare array myImages[0]="images/img1.jpg" // load array myImages[1]="images/img2.jpg" myImages[2]="images/img3.jpg" myImages[3]="images/img4.jpg" myImages[4]="images/img5.jpg" myImages[5]="images/img6.jpg" Here's the HTML for parent window: <img src="" width="200px" height="200px" id="myimage" name="myimage" /></img> Here's the JS for child window: window.onload = init; function init() { } function first_image() { window.parent.image_object.src = myImages[3]; //Problem happens here I think document.getElementById("myimage")window.parent.src = window.parent.image_object.src; } The HTML Child Window <h1>My Remote</h1> <a href="#" id="first" onclick="first_image()" >First Image</a> </br>

It is possible?

Clarification of a some code

- by Legend

I have come across a website that appears to use Ajax but does not include any js file except one file called ajax.js which has the following: function run(c, f, b, a, d) { var e = null; if (b && f) { document.getElementById(b).innerHTML = f } if (window.XMLHttpRequest) { e = new XMLHttpRequest() } else { if (window.ActiveXObject) { e = new ActiveXObject(Microsoft.XMLHTTP) } } e.onreadystatechange = function () { if (e.readyState == 4) { if (e.status == 200 || e.statusText == "OK") { if (b) { document.getElementById(b).innerHTML = e.responseText } if (a) { setTimeout(a, 0) } } else { console.log("AJAX Error: " + e.status + " | " + e.statusText); if (b && d != 1) { document.getElementById(b).innerHTML = "AJAX Error. Please try refreshing." } } } }; e.open("GET", c, true); e.setRequestHeader("Content-Type", "application/x-www-form-urlencoded"); e.send(null) } Like you might have guessed, the way it issues queries inside the page with queries like this: run('page.php',loadingText,'ajax-test', 'LoadSamples()'); I must admit that this is the first time I've seen a page from which I could not figure how things are being done. I have a few questions: Is this Server-Side Ajax or something similar? If not, can someone clarify what exactly is this? Why does one use this? Is it for hiding the design details? (which are otherwise revealed in plain text by javascript) How difficult would it be to convert my existing application into this design pattern? (maybe a subjective question but any short suggestion will do) Any suggestions?

ASP disable button during postback

- by user667430

I have a button which i am trying to add a css class to appear disabled once the user has clicked it. protected void Button_Continue_OnClick(object sender, EventArgs e) { Panel_Error.Visible = false; Literal_Error.Text = ""; if (RadioButton_Yes.Checked) { ...//if radio checked get text and process etc. } } My button onlick is above which simply processes a textbox filled on the page. My button looks like this: <asp:Button runat="server" ID="Button_Continue" CssClass="button dis small" Text="Continue" OnClick="Button_Continue_OnClick" ClientIDMode="Static" OnClientClick="return preventMult();" /> And my javscript is as follows: <script type="text/javascript"> var isSubmitted = false; function preventMult() { if (isSubmitted == false) { $('#Button_Continue').removeClass('ready'); $('#Button_Continue').addClass('disabled'); isSubmitted = true; return true; } else { return false; } } </script> The problem I am having is that the css class added works fine on the first postback, but after which my button onclick doesnt work and the button cant be clicked again if the user needs to resubmit the data if it is wrong Another problem I am having is that with a breakpoint in my method i notice that the method is fired twice on the click.

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?

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.

Why does cloning the django inline formsets result to forms with similar ids and names?

- by user1289167

In my project I use django inline formsets. I got the jquery to clone the formsets but unfortunately the cloned forms have the same names and ids and so data entered in the last one overwrites the data from the first form. What could I be doing wrong? Here is the script: <script type="text/javascript">> function cloneMore(selector, type) { var newElement = $(selector).clone(true); var total = $('#id_' + type + '-TOTAL_FORMS').val(); newElement.find(':input').each(function() { var name = $(this).attr('name').replace('-' + (total-1) + '-','-' + total + '-'); var id = 'id_' + name; $(this).attr({'name': name, 'id': id}).val('').removeAttr('checked'); }); newElement.find('label').each(function() { var newFor = $(this).attr('for').replace('-' + (total-1) + '-','-' + total + '-'); $(this).attr('for', newFor); }); total++; $('#id_' + type + '-TOTAL_FORMS').val(total); $(selector).after(newElement); } </script>

Elegent methods for caching search results from RESTful service?

- by Paul

I have a RESTful web service which I access from the browser using JavaScript. As an example, say that this web service returns a list of all the Message resources assigned to me when I send a GET request to /messages/me. For performance reasons, I'd like to cache this response so that I don't have to re-fetch it every time I visit my Manage Messages web page. The cached response would expire after 5 minutes. If a Message resource is created "behind my back", say by the system admin, it's possible that I won't know about it for up to 5 minutes, until the cached search response expires and is re-fetched. This is acceptable, because it creates no confusion for me. However if I create a new Message resource which I know should be part of the search response, it becomes confusing when it doesn't appear on my Manage Messages page immediately. In general, when I knowingly create/delete/update a resource that invalidates a cached search response, I need that cached response to be expired/flushed immediately. The core problem which I can't figure out: I see no simple way of connecting the task of creating/deleting/updating a resource with the task of expiring the appropriate cached responses. In this example it seems simple, I could manually expire the cached search response whenever I create/delete/update a(ny) Message resource. But in a more complex system, keeping track of which search responses to expire under what circumstances will get clumsy quickly. If someone could suggest a simple solution or some clarifying thoughts, I'd appreciate it.

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.

HTML5 card game [closed]

- by ChrisCa

I created a card game in silverlight a year or so ago in order to learn a bit about Silverlight. I am now wanting to make a HTML5 version of the game in an effort to learn a little bit more about that. I am thinking I'd like to take advantage of stuff like Knockout.js and WebSockets and the canvas element. Now what I'm confused about is how to lay out the cards on the screen. With Silverlight I was able to make a "Hand" control, which was made up of two sub controls - the cards the player has in their hand and the ones they have on the table. And they in turn were made up of Card controls. Now I don't believe there is the concept on a User Control in javascript. So I am possibly thinking about this in entirely the wrong way. So my question is - how could I lay out some cards on the table and perhaps make reuse of something for each player? I have a client side JSON object called game, which contains an array of players. Each player has a hand which is made up of an array of in-hand cards and on-table cards. Ideally I would like to bind these to something using Knockout.js - but I don't know what I could bind to. Would I simply position images (of cards) on a canvas? Is there a way to make some kind of Hand object that each player could have and that I could bind to? Any advice? Or sample code you've seen elsewhere?

How to append query parameter at runtime using jQuery

- by Wondering

Through JavaScript I am appending one query parameter to the page url and I am facing one strange behaiviour. <div> <a href="Default3.aspx?id=2">Click me</a> </div> $(function () { window.location.href = window.location.href + "&q=" + "aa"; }); Now I am appending &q=aa in default3.aspx and in this page the &q=aa is getting added continuously, causing the URL to become: http://localhost:1112/WebSite2/Default3.aspx?id=2&q=aa&q=aa&q=aa&q=aa&q=aa&q=aa&q=aa&q=aa&q=aa&q=aa&q=aa&q=aa&q=aa&q=aa&q=aa&q=aa&q=aa&q=aa&q=aa&q=aa&q=aa One would say just pass it like <a href="Default3.aspx?id=2&q=aa">Click me</a>, but I cant do that. The value of this query parameter is actually the value of an HTML element which is in default3.aspx. I have to add it in runtime. What are the ways to achieve this?

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"/>

How to store arbitrary data for some HTML tags

- by nickf

I'm making a page which has some interaction provided by javascript. Just as an example: links which send an AJAX request to get the content of articles and then display that data in a div. Obviously in this example, I need each link to store an extra bit of information: the id of the article. The way I've been handling it in case was to put that information in the href link this: <a class="article" href="#5"> I then use jQuery to find the a.article elements and attach the appropriate event handler. (don't get too hung up on the usability or semantics here, it's just an example) Anyway, this method works, but it smells a bit, and isn't extensible at all (what happens if the click function has more than one parameter? what if some of those parameters are optional?) The immediately obvious answer was to use attributes on the element. I mean, that's what they're for, right? (Kind of). <a articleid="5" href="link/for/non-js-users.html"> In my recent question I asked if this method was valid, and it turns out that short of defining my own DTD (I don't), then no, it's not valid or reliable. A common response was to put the data into the class attribute (though that might have been because of my poorly-chosen example), but to me, this smells even more. Yes it's technically valid, but it's not a great solution. Another method I'd used in the past was to actually generate some JS and insert it into the page in a <script> tag, creating a struct which would associate with the object. var myData = { link0 : { articleId : 5, target : '#showMessage' // etc... }, link1 : { articleId : 13 } }; <a href="..." id="link0"> But this can be a real pain in butt to maintain and is generally just very messy. So, to get to the question, how do you store arbitrary pieces of information for HTML tags?

Why is the operation address incremented by two?

- by Gavin Jones

I am looking at a Javascript emulator of a NES to try and understand how it works. On this line: addr = this.load(opaddr+2); The opcode is incremented by two. However, the documentation (see appendix E) I'm reading says: Zero page addressing uses a single operand which serves as a pointer to an address in zero page ($0000-$00FF) where the data to be operated on can be found. By using zero page addressing, only one byte is needed for the operand, so the instruction is shorter and, therefore, faster to execute than with addressing modes which take two operands. An example of a zero page instruction is AND $12. So if the operand's argument is only one byte, shouldn't it appear directly after it, and be + 1 instead of + 2? Why +2? This is how I think it works, which may be incorrect. Suppose our memory looks like: ------------------------- | 0 | 1 | 2 | 3 | 4 | 5 | <- index ------------------------- | a | b | c | d | e | f | <- memory ------------------------- ^ \ PC and our PC is 0, pointing to a. For this cycle, we say that the opcode: var pc= 0; //for example's sake var opcode= memory[pc]; //a So shouldn't the first operand be the next slot, i.e. b? var first_operand = memory[pc + 1]; //b

listbox select count not work dont work

The function is called, but it doesn't count the number of the selected options. <select name="element_17_1[ ]" size="7" multiple="multiple" class="element select medium" id="element_17_1[ ]" onfocus="selectCount(this.form);" onClick="selectCount(this.form);" > <option value="Opt1">Opt1</option> <option value="Opt2">Opt2</option> <option value="Opt3">Opt3</option> <option value="Opt4">Opt4</option> <option value="Opt5">Opt5</option> <option value="Opt6">Opt6</option> <option value="Opt7">Opt7</option> </select> and this is the function I tried in the <head> function selectCount(f) { var selObj = myForm.elements['element_17_1[]']; var totalChecked = 0; for (i = 0; i < selObj.options.length; i++) { if (selObj.options[i].selected) { totalChecked++; } } f.element_9.value = totalChecked; }

The current implementation doesn't do anything javascript <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.5.1/jquery.min.js"></script> <script> $(document).ready(function (){ //$(this).animate(function(){ $('html, body').animate({ scrollTop: $("#test4").offset().top }, 2000); //}); }); </script> html <div class="row"> <div class = "span12"> <div class = "row"> <div class = "span2"> <div style="height:480px;font:12px Georgia, Garamond, Serif;overflow:auto;"> <div id = "test1">Test1</div> <div id = "test2">Test2</div> <div id = "test3">Test3</div> <div id = "test4">Test4</div> </div> </div> <div class = "row"> <div class = "span8"> Other content on the page </div> </div> </div> </div> </div>

Returning a Value from a jQuery Dialog Button Instead of Running a Function

- by kamera

I'm working on an admin UI and I can't wrap my head around how to get a specific kind of modal behaviour. I'm using jQuery. I already have a system for modal dialogs in place, where an openModal(settings) function opens a modal. Based on the settings, it will show/hide or sometimes inject various dialogs. I also have a generic confirmation dialog and this is the one I'm not sure how to make work. The layout is simple: <div id="confirmation-dialog"> <h2>Are you sure?</h2> <button class="button.yes">Yes</button> <button class="button.no">No</button> </div> I could just hard-code each button to do what I need it to do but I would like this to be more generic. Ideally, I would like it to function like this: (I know this doesn't work) function deleteImportantThing() { if (confirmThis() == true) { // Delete the thing } else { // Do nothing, close dialog } } function confirmThis() { openModal({kind: "confirm"}); // Check which button is clicked, then return true or false } I guess I just don't know enough JavaScript to get this to work, or to even figure out where to look. Any advice? I know there are modal dialog plug-ins out there but I'd have to change how the rest of my modals work to integrate them, and I'd like to do this myself if at all possible.

Ajax Code to run PHP query After Facebook Like Button is Clicked

- by John

I have the PHP below on a file called fblike.php. On another file, I have the Facebook Like button. The Like button functions. I would like to run the code below when the Facebook Like button is clicked. I know that FB.Event.subscribe('edge.create', function(response) {} is supposed to run whenever the Like button is clicked. I know that I am probably supposed to use Javascript and maybe Ajax to cause the PHP on fblike.php to run. But after multiple tries, I can't get it to work. What is the specific Ajax code that I could include within the Facebook Event? Do I need to do anything to the Like button code to allow the Facebook Event to work? $submissionid = $_POST['submissionid']; $uid = $_POST['uid']; mysql_connect("server", "username", "password") or die(mysql_error()); mysql_select_db("database") or die(mysql_error()); $q = "INSERT INTO fblikes VALUES (NULL, '$submissionid', '$uid', NULL)"; $r = mysql_query($q); if($r) { echo "Success!"; } elseif(!$r) { echo "Failed!"; }
