JavaScript - Addevent() In Javascript
Code:
addEvent(document.getElementById('myinput'), 'blur', function(event) { alert('The element lost focus (blurred)'); }); Is addEvent() a built-in functionality in JavaScript ? If not, then how will JavaScript understand it when it is used for an event ? Thanks Similar TutorialsI have more than 30 addEvent listeners i need to add to my WebApp. But the Code to dynamically add them is not working, unless change: Code: AddItemEvtAry[x].addEventListener('click', function (e) {document.getElementById("text" + x).value ++}, false); to Code: AddItemEvtAry[x].addEventListener('click', function (e) {document.getElementById("text0").value ++}, false); but obviously hardcoding all of those DIV IDs would defeat the purpose of the code. Code in Question: Code: // Event Listeners for Incrimenting Quantities var AddItemEvtAry = [40]; for(var x = 0; x < 39; x++) { AddItemEvtAry[x] = document.getElementById("AddItem" + x); } for(var x = 0; x < 39; x++) { AddItemEvtAry[x].addEventListener('click', function (e) {document.getElementById("text0").value ++}, false); } This code is finally working, but for some reason no matter which button i click on, it is always returning "9". It should be firing the alert(x), where x is the x index value for that particular addEventListener Code: .addEventListener('click', function (e) {alert(x);}, Code: <html> <script type="text/javascript"> document.addEventListener('DOMContentLoaded', DOMLoadedEventFunction, false); function DOMLoadedEventFunction () { for(var x = 0; x < 9; x++) { document.getElementById('btn' + x).addEventListener('click', function (e) {alert(x);}, false); } } </script> <body> <input type="button" id="btn0" value="1"> <input type="button" id="btn1" value="2"> <input type="button" id="btn2" value="3"> <input type="button" id="btn3" value="4"> <input type="button" id="btn4" value="5"> <input type="button" id="btn5" value="6"> <input type="button" id="btn6" value="7"> <input type="button" id="btn7" value="8"> <input type="button" id="btn8" value="9"> <input type="button" id="btn9" value="10"> </body> </html> This is just some sample code that i will later turn into an HTML5 File Manager 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 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. 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 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']); $('html, body').animate({ scrollTop: 0 }, 'slow'); } } }); }); //--></script> And this is how I want the format of the function to be: function testsession() { if there is a session called 'hiredate' { activate the script above } else { var el = document.getElementById("product_data"); } } I just dont know how to write this in javascript Could you help me if possible please I got an index.php Code: <html> <form action="bacakomik.php" method='post'> <select name="kodekomik"> <option value='../komik1/|23'>Judul Komik1</option> <option value="../komik2/|20">Judul Komik2</option> <option value="../komik3/|10">Juduk Komik3</option> <option value="../komik4/|20">Judul Komik4</option> </select> <input type="submit" /> </form> <?php echo ('<select>'); echo ('<option value= "'.$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... 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? I am having trouble modifying this to make the number of guesses limited to 5 and if guessed under 5 guesses prints pass otherwise prints failed. Thanks for the help. var mycolor = 'green'; var guess = ''; while (guess != mycolor){ guess = prompt("Guess my color:"); } println('You guessed it!'); I would like to put an ad delay onto a webpage. No content shows up (complete white backgorund) until 30 seconds after viewing the ad. The ad would disappear and the content of the page would load up.
Hi guy's Not sure if what i want to do is possible, i am a very basic computer user and any help would be great. i have a relay that is conect to my router and if i type the following into the address bar it turns it on for 2 seconds.

Because xsl lacks commands that will allow me to create repetitive <options> I am using javascript. A sample xml file that I am using is bellow. Code: <?xml version="1.0" encoding="ISO-8859-1"?> <?xml-stylesheet type="text/xsl" href="a.xsl"?> <Country> <California> <County>San Diego</County> <County>Los Angeles</County> </California> <Nevada> <County>Reno</County> <County>Las Vegas</County> </Nevada> </Country> The xsl file that I'm using is show below. Code: <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:template match="/"> <html> <head></head> <body> <p>This loaded</p> <form> <select name='County'> <script type="text/javascript"> var i=3; while(i > 0){ document.write("<option><xsl:value-of select='Country/California/County["); document.write(2); document.write("]'/></option>"); i--; } </script> </select> </form> <script type="text/javascript"> var i=3; while(i > 0){ document.write("<xsl:value-of select='Country/California/County["); document.write(2); document.write("]' /> <br />"); document.write("<xsl:value-of select='Country/California/County[2]'/><br />"); i--; } </script> </body> </html> </xsl:template> </xsl:stylesheet> Bassically all I'm trying to do is list the counties under california. My problem is that the javascript will print the list no problem but it only prints san diego even if my xpath index = i, is set to two. When i is set to 2, it should display Los Angeles. The following sample code will display Los Angeles Code: document.write("<xsl:value-of select='Country/California/County[2]' />"); However when the document has i = 1, it should display san diego. Unfortunately when i use i = 2 and write ... Code: document.write("<xsl:value-of select='Country/California/County[" document.write(i); document.write("]' />"); or even Code: document.write("<xsl:value-of select='Country/California/County["); document.write(2); document.write("]' />"); The xsl sheet will display san diego instead. If the code is used without brackets you can see that everything is being displayed correctly ... for instance writting Code: document.write("xsl:value-of select='Country/California/County[" document.write(i); document.write("]' /"); will result in .. Code: xsl:value-of select='Country/California/County[2]' / Why is xsl doing this to me? |
