JavaScript - Javascript Exercises
I'm looking for online Javascript excercises that I can do at home to practise my JavaScript and just basically expand my JavaScript knowledge. I want something that is presented clearly and professionaly, and is also presented in something that resembles an actual excercise that is/would be given to students on a JavaScript course, etc. Something like this is what I am looking for:
http://www.nvcc.edu/home/wpegram/Jav...exercises.html Any sites/pages on the net that have stuff like that on them would be a great resource to me, and would help a lot. Thanks in advance. Similar TutorialsHello all. I have been taking a JavaScript course on Udemy that while has been a very good course as far as I can tell, it has been short on practical exercises. Lots of examples, lots of showing different concepts and methods, etc, just short on the reinforcing and confidence building exercises. Thus, the point to my post here. I wish there were some kind of web developing club here locally but alas if you don't hunt, fish, drink or chew tobacco you are kind of left out, LOL. Well its not that bad, I make fun of it, but sometimes it seems so. At any rate, I'm looking for some kind of resource or something I can participate in that will help me use what I am learning and help me build some experience, etc. I want to get past the 'noob' stage as quickly as I can and as far as I know the quickest way to do that is to start coding even if its really simple stuff and working to more complicated coding. So, does anyone know of such resources? Thanks in advance for your time and help. I have finished studying JS and now testing myself on what I have learned so far by trying these exercises: http://www.nvcc.edu/home/wpegram/Jav...exercises.html This is my code so far for number 1 through 4: Code: <html> <body> <script language="Javascript"> var name = prompt("What is your name?", "Type your name here"); alert("Welcome "+name) var m_names = new Array("January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December"); var d = new Date(); var curr_date = d.getDate(); var curr_month = d.getMonth(); var curr_year = d.getFullYear(); document.write(m_names [curr_month] + " " + curr_date + "," + " " + curr_year + "."); document.lastModified; document.write(document.lastModified); </script> </body> </html> Regarding number 4: Code: 4. Display the last modified date of the document. I am having a problem: 1] The output from the above code is: May 31, 2011.05/31/2011 10:13:13 So it's lining up questions numbers 3 and 4 on the same line, how can I get 3 and 4 on separate lines please? Hello! I am trying to find a script that allows you to open multiple browser tabs and then close each of those tabs, either one by one or all at once. Does anyone know how to do this please? Thanks so much for your help. I want to have another go at Javascript. I have several books on the subject but I find that my eyesight is a major problem. Therefore I want to try an on-line solution, preferably free. I have Googled, but there are so many that I am almost dizzy with the choices. Perhaps someone could recommend one. Not too fussy visually. My knowledge is VERY basic. Frank Does anyone know how to make URL links that use Javascript still work when users have Javascript disabled on their browser? The only reason I'm using JS on a URL is because my link opens a PDF file, and I'm forcing it not to cache so users have the latest version. I tried the <script><noscript> tags, but I'm not sure if I'm using it correctly, as my URL completely disappears. Below is my HTML/Javascript code: <p class="download"> <script type="text/javascript">document.write("<span style=\"text-decoration: underline;\"><a href=\"javascript:void(0);\" onclick=\"window.open( 'http://www.webchild.com.au/mediakit/Direct_Media_Kit_Web.pdf?nocache='+ Math.floor( Math.random()*11 ) );\" >The Child Magazines Media Kit</a></span> (PDF 1 MB) ");</script> <noscript><span style="text-decoration: underline;"><a href="http://www.webchild.com.au/mediakit/Direct_Media_Kit_Web.pdf" >The Child Magazines Media Kit</a></span> (PDF 1 MB)</noscript> </p> Thanks for any help, Michael Hi Guys, I am new at JavaScript and start to do some tutorials.What I am trying to do here is prompting user to input a name and if the name was valid the page(document) will display with all objects like the button.But if user enter a wrong name then the button will be disabled! I create the following code but it did not work <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>New Web Project</title> <script language="JavaScript" type=""> function changeColor(){ document.bgColor = "Gray"; } </script> </head> <body> <script language="JavaScript" type="text/javascript"> var person = ""; person = prompt('What is Your Name:'); if (person == "Foo") { document.write("<h1 />Welcome " + person); document.bgColor = "Yellow"; } else { document.write("<h1 />Access Denied!!!!"); document.bgColor = "Red"; document.getElementById("gree").disabled = true; } </script> <div> <p/><input id="gree" type="button" value="Gray " onClick="changeColor();"> </div> </body> </html> as you can see I used the: document.getElementById("gree").disabled = true; but it did not work , could you please give an idea how I can solve this problem? Thanks Hi, I have the following code snippet: test.html ====== <script language="javascript" type="text/javascript"> var testVariable = "test"; </script> <script language="javascript" type="text/javascript" src="test.js"> </script> test.js ===== var testVariable = window.top.testVariable; In firefox, I'm able to access testvariable defined within test.html in test.js. But in chrome, test.js couldnot get the window.top.testVariable field defined in test.html. Can any one please let me know how i can make it work in chrome?. Am i missing something here?. I got an index.php Code: <html> <form action="bacakomik.php" method='post'> <select name="kodekomik"> <option value='../komik1/|23'>Judul Komik1</option> <option value="../komik2/|20">Judul Komik2</option> <option value="../komik3/|10">Juduk Komik3</option> <option value="../komik4/|20">Judul Komik4</option> </select> <input type="submit" /> </form> <?php echo ('<select>'); echo ('<option value= "'.$i.'">'.'Page '.$i.'</option>'); echo ('</select>'); ?> </html> As you can see, each of the option brings specific value "../komik1/|23" komik1 is a directory | is a delimiter 23 is the pages in one chapter and can be considered also as how many images are there on a specific directory This is my bacakomik.php Code: <?php $dirkomik = $_POST['kodekomik']; $exploded = explode("|", $dirkomik); echo ($exploded[0]); //picture directory echo ("<br>"); echo ($exploded[1]); //total page in the comic $pagecount = (int)$exploded[1]; //Take last posted value, process it right away echo ('<FORM name="guideform"> '); echo ('<select name="guidelinks">'); $i=1; do { echo ('<option value= "'.$i.'">'.'Page '.$i.'</option>'); $i= $i+1; }while($i <= $pagecount); //Printing option and select echo ("</select>"); ?> <input type="button" name="go" value="Go!" onClick="document.getElementById('im').src=document.guideform.guidelinks.options[document.guideform.guidelinks.selectedIndex].value+'.png';"> </FORM> <img src="img0.jpg" id="im"> With the current code on bacakomik.php, I only can change the img src of id "im" in the same directory only. What I want is that the Javascript could "add" the "$exploded[0]" variable so that the picture can be loaded from different directory. Anyone can do this? I believe that the fix should be somewhere on input tag inside OnClick, or do you know where? Anyway, I found this on the net http://p2p.wrox.com/php-faqs/11606-q...avascript.html Please help me to those who can...

I want to be able to activate this piece of code using another javascript function. This is the code I want to activate: Code: <script type="text/javascript"><!-- $('#button-cart').bind('click', function() { $.ajax({ url: 'index.php?route=checkout/cart/update', type: 'post', data: $('.product-info input[type=\'text\'], .product-info input[type=\'hidden\'], .product-info input[type=\'radio\']:checked, .product-info input[type=\'checkbox\']:checked, .product-info select, .product-info textarea, .date_data input[type=\'text\']'), dataType: 'json', success: function(json) { $('.success, .warning, .attention, information, .error').remove(); if (json['error']) { if (json['error']['warning']) { $('#notification').html('<div class="warning" style="display: none;">' + json['error']['warning'] + '<img src="catalog/view/theme/default/image/close.png" alt="" class="close" /></div>'); $('.warning').fadeIn('slow'); } for (i in json['error']) { $('#option-' + i).after('<span class="error">' + json['error'][i] + '</span>'); } } if (json['success']) { $('#notification').html('<div class="success" style="display: none;">' + json['success'] + '<img src="catalog/view/theme/default/image/close.png" alt="" class="close" /></div>'); $('.success').fadeIn('slow'); $('#cart_total').html(json['total']); $('html, body').animate({ scrollTop: 0 }, 'slow'); } } }); }); //--></script> And this is how I want the format of the function to be: function testsession() { if there is a session called 'hiredate' { activate the script above } else { var el = document.getElementById("product_data"); } } I just dont know how to write this in javascript Could you help me if possible please I want to insert this js snippet Code: function addText(smiley) { document.getElementById('message').value += " " + smiley + " "; document.getElementById('message').focus(); return false; } to a loaded iframe with name&id chtifrm. I can access it & change embed something in its html via using something like: Code: $(parent.chtifrm.document.body).append('<div id=\"smly\" style=\"cursor:pointer;float:left;top:200px;display:none;position:absolute;\"><\/div>'); .... Code: parent.chtifrm.document.getElementById('chatbox_option_disco').style.display == 'none' but how do I insert js in the head of loaded iframe? All -- I have a JavaScript config file called gameSetting.js which contains a bunch of variables which configures a particular game. I also have a shared JavaScript library which uses the variables in gameSetting.js, which I include like so: <script type="text/javascript" src="gameSetting.js" ></script> <script type="text/javascript" src="gameLibrary.js" ></script> In gameSetting.js I have: $(document).ready(function() { // call some functions / classes in gameLibrary.js } in Firefox, Safari, and Chrome, this works fine. However, in IE, when it's parsing gameSetting.js, it complains that the functions that live in gameLibrary.js aren't defined. When it gets to parsing gameLibrary.js, the variables in gameSetting.js are reported as not being defined. I've tried dynamically bootstrapping the gameLibrary file using this function in document.ready for dynamic load... $.getScript("gameLibrary.js"); However, the same problem still happens in IE, where when it parses the files individually it's not taking into context the file/variables that came before, so it's not an out of load order problem. My options a 1) collapsing all the functions in gameLibrary.js and variables in gameSetting.js into one file. However, this is not practical because this is dealing with literally hundreds of games, and having a gameLibrary.js in ONE location for ONE update is what makes most logical sense. 2) figure out a way to get this to work where variables in file1 are accessible to file2 in IE (as it seems they are in other browsers). jQuery seems to be able to have multiple plugins that all refer to the based jQuery-1.3.2.js, so I know there is a way to get this to work. Help appreciated. Nero I wrote a log function that took note of various function calls. Thinking that functions are first class objects, and objects have properties, I made the name of each logged function a property of that function, e.g., brightenInnerPara.name = "brightenInnerPara"; Every browser I tried (Firefox, MSIE, Opera, Chrome, Safari) accepted the assignment, no problem. In Firefox and MSIE, the result was what I wanted: brightenInnerPara.name == "brightenInnerPara" But in the others, the result was: brightenInnerPara.name == null Question 1. Which Javascript is correct here? I favor Firefox and MSIE, not merely because they were willing to give me what I wanted, but also because it makes no sense to accept an assignment statement without throwing an error and then give it a null semantics, like Chrome, Opera, and Safari did. I found a workaround, using assignments like this: brightenInnerPara.prototype.name = "brightenInnerPara"; To my surprise, that worked in every browser. But I don't know why. It seems that such assignments are enough to cause each function to have its own distinct prototype. Question 2. Just how inefficient is my workaround, and why does it work? Hi to all, I'm a php person and I have a problem: I need to attach another value when an option is selected, the code below is only part of it but maybe you can see what I want to do. When an option is selected $username I need allso $id, can I do a appendChild or something, maybe my question is a bit stupid. Code: var newTextbox = document.createElement('select'); newTextbox.className = 'fn-select'; newTextbox.name = "opcion"; var op1 = new Option("", "<?php echo"$username" ?>"); newTextbox.appendChild(op1); var txt1 = document.createTextNode('<?php echo"$username" ?>'); op1.appendChild(txt1); editAreaText.appendChild(newTextbox); editArea.appendChild(editAreaText); Here is the full script including the php: PHP Code: <!-- Populate list with friends START--> var newTextbox = document.createElement('select'); newTextbox.className = 'fn-select'; newTextbox.name = "opcion"; //First user in the populated select menu is the person Loged in var op1 = new Option("", "<?php echo"$username"; ?>"); newTextbox.appendChild(op1); var txt1 = document.createTextNode('Me | <?php echo"$username"; ?>'); op1.appendChild(txt1); //Next users are my friends in the database <?php mysql_select_db("dnlife", $con); $result = mysql_query("SELECT * FROM `dnl_friends` WHERE `user_id` = '$id' OR `friends_id` = '$id'"); if(mysql_num_rows($result)) { while($row = mysql_fetch_array($result)) { $current = ($row['user_id'] == $id)?$row['friends_id']:$row['user_id']; //With each id now we get the name from database $lista_amigos = mysql_query("SELECT * FROM `dnl_users` WHERE `id` = '$current'"); $i = "1"; $op = $i++; while($row_users = mysql_fetch_array($lista_amigos)) { echo " var op".$op." = new Option(\"\", \"$row_users[nombre]\"); newTextbox.appendChild(op".$op."); var txt".$op." = document.createTextNode('$row_users[nombre]'); op".$op.".appendChild(txt".$op."); "; }}} else { echo ""; } ?> editAreaText.appendChild(newTextbox); editArea.appendChild(editAreaText); <!-- Populate list with friends END--> I had someone tweek a website for me. jQuery works fine on his server, on my site www.gamesgaze.com, I get the following message: Webpage error details User Agent: Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 5.1; Trident/4.0) Timestamp: Thu, 14 Oct 2010 21:15:34 UTC Message: 'nodeName' is null or not an object Line: 981 Char: 3 Code: 0 URI: http://www.gamesgaze.com/plugins/sit...query-1.4.1.js and this is the line in jquery-1.4.1.js that is causing the problem data: function( elem, name, data ) { if ( elem.nodeName && jQuery.noData[elem.nodeName.toLowerCase()] ) { return; What do you guys and gals think is causing this issue? My developer can't seem to figure this out. I am grateful for any info that could help me resolve this issue. Michael. I'm learning JavaScript. My suspicions for all these years would be I'd hate it, and it I was right. It seems I have to write half a page to perform something so simple. Anyway, a question: Do I have to end **** with a ; always? {example;} Hi I am trying to remove spaces from the 'username' field but leave the spaces in the first and last name fields. The below code removes *one* space from the string but no more. Code: <html> <head> <title> </title> <script language="javascript"> function makename() { var firstname = document.mine.firstname.value; var lastname = document.mine.lastname.value; var username = firstname + "." + lastname; document.mine.username.value = (username.replace(" ", "")); } </script> </head> <body> <form name="mine" method="post"> UserName <input type="text" name="username" readonly/> <br />First Name <input type="text" name="firstname" onkeyup="makename()"/> <br />Last Name <input type="text" name="lastname" onkeyup="makename()" /> <p><input type="submit" /> </form> </body> </html> I am thinking I need to run a do, while loop eg. Code: do { document.mine.username.value = (username.replace(" ","")); } while (username still contains space) But I am not sure how to define username still contains space I have a calendar I made myself. What I want is to open it in a new window, each date is a link, when clicked the date is returned to the original page. How do I do that?? I have searched and found that it is not to hard to make the calendar to open in a new window, but how do I fix the date to be passed along on click?? Yeah, forgot to say I want the date to be returned to a form field... sorry about my english... i have logo slider in javascript this is the code: var displayWaitMessage=true; // Display a please wait message while images are loading? var activeImage = false; var imageGalleryLeftPos = false; var imageGalleryWidth = false; var imageGalleryObj = false; var maxGalleryXPos = false; var slideSpeed = -1; var imageGalleryCaptions = new Array(); function startSlide(e) { if(document.all)e = event; var id = this.id; if(this.id=='arrow_right'){ slideSpeedMultiply = Math.floor((e.clientX - this.offsetLeft) / 5); slideSpeed = -1*slideSpeedMultiply; slideSpeed = Math.max(-10,slideSpeed); }else{ slideSpeedMultiply = 10 - Math.floor((e.clientX - this.offsetLeft) / 5); slideSpeed = 1*slideSpeedMultiply; slideSpeed = Math.min(10,slideSpeed); if(slideSpeed<0)slideSpeed=10; } } function releaseSlide() { var id = this.id; slideSpeed=-1; } function gallerySlide() { if(slideSpeed!=0){ var leftPos = imageGalleryObj.offsetLeft; leftPos = leftPos/1 + slideSpeed; if(leftPos>maxGalleryXPos){ leftPos = maxGalleryXPos; slideSpeed = 0; } if(leftPos<minGalleryXPos){ leftPos = minGalleryXPos; slideSpeed=0; } imageGalleryObj.style.left = leftPos + 'px'; } setTimeout('gallerySlide()',50); } function showImage() { if(activeImage){ activeImage.style.filter = 'alpha(opacity=50)'; activeImage.style.opacity = 0.5; } this.style.filter = 'alpha(opacity=100)'; this.style.opacity = 1; activeImage = this; } function initSlideShow() { document.getElementById('arrow_left').onmousemove = startSlide; document.getElementById('arrow_left').onmouseout = releaseSlide; document.getElementById('arrow_right').onmousemove = startSlide; document.getElementById('arrow_right').onmouseout = releaseSlide; imageGalleryObj = document.getElementById('theImages'); imageGalleryLeftPos = imageGalleryObj.offsetLeft; imageGalleryWidth = document.getElementById('galleryContainer').offsetWidth - 80; maxGalleryXPos = imageGalleryObj.offsetLeft; minGalleryXPos = imageGalleryWidth - document.getElementById('slideEnd').offsetLeft; var slideshowImages = imageGalleryObj.getElementsByTagName('IMG'); for(var no=0;no<slideshowImages.length;no++){ slideshowImages[no].onmouseover = showImage; } var divs = imageGalleryObj.getElementsByTagName('DIV'); for(var no=0;no<divs.length;no++){ if(divs[no].className=='imageCaption')imageGalleryCaptions[imageGalleryCaptions.length] = divs[no].innerHTML; } gallerySlide(); } function showPreview(imagePath,imageIndex){ var subImages = document.getElementById('previewPane').getElementsByTagName('IMG'); if(subImages.length==0){ var img = document.createElement('IMG'); document.getElementById('previewPane').appendChild(img); }else img = subImages[0]; if(displayWaitMessage){ document.getElementById('waitMessage').style.display='inline'; } document.getElementById('largeImageCaption').style.display='none'; img.onload = function() { hideWaitMessageAndShowCaption(imageIndex-1); }; img.src = imagePath; } function hideWaitMessageAndShowCaption(imageIndex) { document.getElementById('waitMessage').style.display='none'; document.getElementById('largeImageCaption').innerHTML = imageGalleryCaptions[imageIndex]; document.getElementById('largeImageCaption').style.display='block'; } window.onload = initSlideShow; now when it's get to the last logo the slider is stop, and you can move with the arrow right and left and want to change that the slider don't stop and keep move in looping. i really need help! thank you very much. I downloaded a javascript file that works GREAT. It shows and hides div's in the code on demand. My problem is that in my code the divs in question are forms that are submitted. The handler for the forms is the same page. So the first time I visit the page all the sections are hidden. I expand a div, add some information and submit. Then the page refreshes and all divs are hidden again. I have to reexpand the div again to continue my work. Not a HUGE deal except when I have a ton of data entry to do. So I have a plan. I have created a table in the data base to hold a 1/0 value. I want the javascript that shows the sections to simply check the table. IE if the page is loaded, check the database to see which sections should be hidden and which should be visible. I THINK the place to add it is the fuction called "showhide" on line 53 but I'm not sure if that's correct nor do I have any idea how to make it accept the value from the database. Whew! I hope I made that clear. Below is the code for the javascript and the code of the webpage in question. Can anyone help?
