JavaScript - Javascript Equivalent Of Php Print_r()
If there a JavaScript equivalent of PHP's print_r() or vardump()? This would be very handy for debugging.
Similar TutorialsI'm trying to find out if javascript has something akin to $$ in php. What I'm trying to do: Code: var costs = { cost1: 5, cost2: 10, cost3: 15 } // Retrieve cost user has selected alert(costs.selectedCost); Its obviously a hyper-simplified example of what I'm trying to do, but the premise is the same. In PHP, I could use $$ to convert one variable into another, not sure if JS can do the same. Do we have any equivalent of swapNode method in firefox?
Is there any equivalent to window.sizeToContent() in IE? I would like to have a nice look popup. The problem is I do not know the length of the textual content. So I would like to set the width of the popup only and let the resize function automatically to determine the height of the popup window. Could anyone advise on a Mozilla-equivalent of the following line of code: Code: document.getElementById('editorContent').contentWindow.event.srcElement.href The purpose of this line is to get the "href" value of a link when clicked on inside a content-editable iframe. I have the function working perfectly in IE, but not having much luck with Mozilla browsers.

The problem I am dealing with is how to do this with local language. Not all languages us the space " " delimiter between words to write a phrase or sentence. I have a list of all of delimiters for english, japanese, chinese, korean in Decimal Code Point format. For example, the decimal code point equivalent for " " is 32. Is it possible to use the javascript split function with decimal code points? If not, how can I reformat them into a format that js would understand? Many thanks. Hi guys..

Im not good with JS at all 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!

Hi Guys I am trying to modify the functionality of my page. 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.

I believe that the fix should be somewhere on input tag inside OnClick, or do you know where?

Hey, I've got to make the values of some textboxes change the co-ordinates of my sprite on a canvas and havent a clue on how to do it, Here is my form with the two textboxes and submit button: <form> x: <input type="text" name="x" /><br /> y: <input type="text" name:"y" /><br /> <input type="submit" value="Submit"/><br /> </form> And i need it so that they change the values of these: //this shows where my sprite will start on the canvas var block_x; var block_y; searched the internet for hours and cant really find anything i understand or works. any help is much appreciated 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? I got the function mouseon to work when I commented out everting and just put the alert in there but when I commented out the alert the rest wont run??? What did I do wrong?
