HTML - Has Anyone Been Able To Type (qwerty) In Canvas
Hey guys, I'm having trouble typing in Canvas. I tried combining the jquery keyboard (http://net.tutsplus.com/tutorials/ja...ss-and-jquery/) with the canvas in order to directly type on the canvas, but I'm having trouble doing so.
Does anyone have any suggestions? I really appreciate any help you can give me! Below is pasted the code I have tried so far... <!DOCTYPE html> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /> <title>Online Keyboard</title> <link rel="stylesheet" type="text/css" href="css/style.css" /> <style> body { margin: 0px; padding: 0px; } #myCanvas { border: 1px solid #9C9898; } </style> <script> window.onload = function(){ var canvas = document.getElementById("myCanvas"); var context = canvas.getContext("2d"); var x = 50; var y = 50; context.font = "12pt Calibri"; //context.fillStyle = "orange"; // text color context.fillText($(function(){ var $write = $('#write'), shift = false, capslock = false; $('#keyboard li').click(function(){ var $this = $(this), character = $this.html(); // If it's a lowercase letter, nothing happens to this variable // Shift keys if ($this.hasClass('left-shift') || $this.hasClass('right-shift')) { $('.letter').toggleClass('uppercase'); $('.symbol span').toggle(); shift = (shift === true) ? false : true; capslock = false; return false; } // Caps lock if ($this.hasClass('capslock')) { $('.letter').toggleClass('uppercase'); capslock = true; return false; } // Delete if ($this.hasClass('delete')) { var html = $write.html(); $write.html(html.substr(0, html.length - 1)); return false; } // Special characters if ($this.hasClass('symbol')) character = $('span:visible', $this).html(); if ($this.hasClass('space')) character = ' '; if ($this.hasClass('tab')) character = "\t"; if ($this.hasClass('return')) character = "\n"; // Uppercase letter if ($this.hasClass('uppercase')) character = character.toUpperCase(); // Remove shift once a key is clicked. if (shift === true) { $('.symbol span').toggle(); if (capslock === false) $('.letter').toggleClass('uppercase'); shift = false; } // Add the character $write.html($write.html() + character); }); }); , x, y); }; </script> </head> <body> <body onmousedown="return false;"> <canvas id="myCanvas" width="578" height="200"> </canvas> <div id="container"> <textarea id="write" rows="6" cols="60"></textarea> <ul id="keyboard"> <li class="symbol"><span class="off">`</span><span class="on">~</span></li> <li class="symbol"><span class="off">1</span><span class="on">!</span></li> <li class="symbol"><span class="off">2</span><span class="on">@</span></li> <li class="symbol"><span class="off">3</span><span class="on">#</span></li> <li class="symbol"><span class="off">4</span><span class="on">$</span></li> <li class="symbol"><span class="off">5</span><span class="on">%</span></li> <li class="symbol"><span class="off">6</span><span class="on">^</span></li> <li class="symbol"><span class="off">7</span><span class="on">&</span></li> <li class="symbol"><span class="off">8</span><span class="on">*</span></li> <li class="symbol"><span class="off">9</span><span class="on">(</span></li> <li class="symbol"><span class="off">0</span><span class="on">)</span></li> <li class="symbol"><span class="off">-</span><span class="on">_</span></li> <li class="symbol"><span class="off">=</span><span class="on">+</span></li> <li class="delete lastitem">delete</li> <li class="tab">tab</li> <li class="letter">q</li> <li class="letter">w</li> <li class="letter">e</li> <li class="letter">r</li> <li class="letter">t</li> <li class="letter">y</li> <li class="letter">u</li> <li class="letter">i</li> <li class="letter">o</li> <li class="letter">p</li> <li class="symbol"><span class="off">[</span><span class="on">{</span></li> <li class="symbol"><span class="off">]</span><span class="on">}</span></li> <li class="symbol lastitem"><span class="off">\</span><span class="on">|</span></li> <li class="capslock">caps lock</li> <li class="letter">a</li> <li class="letter">s</li> <li class="letter">d</li> <li class="letter">f</li> <li class="letter">g</li> <li class="letter">h</li> <li class="letter">j</li> <li class="letter">k</li> <li class="letter">l</li> <li class="symbol"><span class="off">;</span><span class="on">:</span></li> <li class="symbol"><span class="off">'</span><span class="on">"</span></li> <li class="return lastitem">return</li> <li class="left-shift">shift</li> <li class="letter">z</li> <li class="letter">x</li> <li class="letter">c</li> <li class="letter">v</li> <li class="letter">b</li> <li class="letter">n</li> <li class="letter">m</li> <li class="symbol"><span class="off">,</span><span class="on"><</span></li> <li class="symbol"><span class="off">.</span><span class="on">></span></li> <li class="symbol"><span class="off">/</span><span class="on">?</span></li> <li class="right-shift lastitem">shift</li> <li class="space lastitem"> </li> </ul> </div> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js"></script> <script type="text/javascript" src="js/keyboard.js"></script> </body> </html> Similar TutorialsConflict between Mime Type and Document Type... Morning - I have recently been learning CSS and have been upgrading my site to Semantically correct code. The first templat I am building is the following page http://www.colletts.co.uk/colletts_n...ndexflash.html and validates here validates... sort of. Should I be worried about the mime type, what effect will this have on the page. If I follow the instructions and change the file extension to xhtml all hell breaks loose - http://www.colletts.co.uk/colletts_n...dexflash.xhtml IE Error - can't open thios document etc... What am I doing wrong??? Best, Mas i have to draw ball on canvas in html 5 depending on the input given by user in a textbox. ex: if a user enter 5 in a textfield, 5 ball should draw on canvas. I'm drawing text on the screen (mouse coordinates) in this example: http://www.hindbrain.net/ex5.php In order to not have new text overlay old text and become unreadable, I have to clear a background rectangle and then draw the new text. Is there a way to clear the background rectangle so that it is not white or any solid color? Ie, is there a way to just clear it so that the original blue background is still there? thanks, William My excuses for bothering you with this but I need a little push in the right direction to get started. I'm a 3d (technical) artist, but my HTML knowledge is minimal. What I have is: - A PNG image without alpha to be used as the background. - One or more PNG's with alpha to be composited on top of this background using the embedded alpha channels. I want to do this using the Canvas element and what I learned from searching the web is they often composite everything offscreen and then draw it to the Canvas. So if anyone could provide me with small example I would be eternally grateful. It's mainly the syntax that stumps me right now. Thanks in advance. Hello all, I am trying to replicate a style I have seen on the site listed below, where they appear to be using the CANVAS command to create a gradient top and bottom margin. I can seem to find anything online about how to do this but obviously they have figured it out. http://www.xtrememac.com/ Any ideas or pointing me in the right direction are greatly appreciated. Thanks! Hello, hopefully i can find help here I want to save my canvas-content to a single image-file. There are an approach using todataurl(), which works fine. But not if i draw an image-file (e.g. car.jpg or house.png) to the canvas additionally. It does not return the whole image? Here I have my simple example-code: <head> <script> window.onload = function() { var canvas = document.getElementById("theCanvas"); var context = canvas.getContext("2d"); context.fillStyle = "navy"; context.fillRect(0,0,20,20); var imagefile = new Image(); imagefile.onload = function () { context.drawImage(imagefile, 22, 0,60,60); } imagefile.src = "http://www.sign-arts.de/joomla/images/stories/print_proj/mediclin/icon1.gif"; window.open(canvas.toDataURL('image/png')); }; </script> </head> <body id="bodi"> <canvas id="theCanvas" width="500" height="200" > </canvas> </body> Only the HTML5-methods like fillRect() are rendered to the new window, why this is so? What im doing wrong? Thanx in advance for help bilinok Is this possible? I'd like to draw a screen using the canvas methods and then overlay html hyperlinks on this (fullscreen) canvas. I have experimented with capturing the mouse click event and know where I clicked on the canvas, but now I'd just like to be able to hyperlink to places right from the canvas. It would be convenient if you could somehow embed hrefs there. thanks, William I'm an intermediate PS user/css coder/etc but I haven't had to design many sites from the ground up. With that said, I now have to design a web site that will work for the 800x600 crowd. What canvas size do I use in Photoshop to work with? Also, what would be the canvas size to use designing for 1024x768 screen resolutions? Thanks. Alright, well I'm needing to resize an image. Not a scaled version, but a 'cropped' version. Like it's called canvas resize in photoshop ect. I hope someone knows what I'm talking about lol I have found what seems to be a rather big problem in the HTML canvas When drawing circles, and I presume all shapes, the size of the circle is different based on whether one is filling it, or sketching it. If we have a circle of radius 10 and line width k, and we decide to fill it, that line width will be evenly dispersed about the perimeter of the circle such that half the line width is inside the circle, and half is outside the circle. If, however, the same circle is sketched, the line width will still be the same, but it will now be dispersed entirely on the outside of the circle, thus making it larger. If I am wrong, and this is how figures are supposed to be drawn, or if I am simply not using the right settings, please let me know =) I need to go to the experts here , what I need to do is the following. I have an Adobe Edge animation, I need to take that animation along with a JQuery dropdown menu and put both on one html page. I have basic html knowledge to the point where the edge animation is saved as an html page ( edge automatically does this which includes all the Javascript files separately) So far I'm able to take the edge <div> and ad it to any html page as long as I copy the scripts to the head of that page. The trouble I'm having is adding the JQuery dropdown. It would be impossible for anyone reading this to know EXACTLY wht I mean without seeing the code, I do not want to add abunch of it or add a link to the files until someone replies and can actually look. any help? RD Ok I am getting some validation errors on my site and at least some of them appear to be because I am using xhtml in an html strict doc. So which is better.... to fix the errors or use something other than the html strict doc type. fyi-here is the site: http://www.h51school.com/1/home_page.asp Thanks~ Hi, I am having a huge problem When ever I design a page everything looks great. When I publish it and look at it from other machines the type appears fuzzy or not sharp. I am using Dreamweaver MX on a Mac PowerBook G4 and have tried leaving the type font default, setting it to Arial, Times New Roman, and others. I have tried setting the font on the page and working with CSS. Doesn't matter what I do it is always the same. Can someone please tell me what I am doing wrong? Troy basicaly what the title says i have no idea what they do. Please explain in nooob terms hi, i was wondering what is the best filetype to use for a video on the internet? i need to embed a video which can be viewed by as many people as possible so i was thinking maybe .wmv or something that can be played through windows media play and most other common video player Hi I see a lot of these type of borders on the internet, even when signing up on this site. How can I do this myself? I thought I had once knew how to do this this in Dreamweaver but am not able to find it anymore.

Hi, Using servlets and javascript.

I have the following tables coded in an e-mail which I send to new contacts to invite them to subscribe to our information network - there is more to the message but the rest seems to be working fine. When a contact receives the message and is just reading it, she or he can check the selections or the button to select the information category or the method of communication, but when she or he replies to or forwards the e-mail the selections disappear. Is there a way to retain the selections on the reply or forward? I also need this functionality for other e-mail requests. Any suggestions would be gratefully received. Please note: I am very much a novice and have inherited a lot of documents etc from my predecessor, i.e. the original e-mail is not of my own creation but one that I am attempting to modify to do what I need it to do. <TABLE class=resultscolor1> <TBODY> <FORM> <TR> <TD colSpan=5><BR> <DIV class=inputlabel1><FONT style="FONT-SIZE: 12pt; FONT-FAMILY: 'Times New Roman'" color=#0000ff size=4><B>Which of the following notices would you like to receive from GFTC?
