JavaScript - Javascript Basics - Itunes
I am a total noob to JS and need a little help.
Currently writing some small snippets to control iTunes. An example: Code: var iTunesApp = WScript.CreateObject("iTunes.Application");
iTunesApp.LibraryPlaylist.AddFile('B:\\filetoadd.mp4');
Nicely adds a file to the library. Now, i need to set the encoder. I try this: Code: var iTunesApp = WScript.CreateObject("iTunes.Application");
iTunesApp.CurrentEncoder("MP3");
I get: object doesn't support this property of method. iTunes SDK docs: HRESULT IiTunes::CurrentEncoder ( [in] IITEncoder * iEncoder ) Sets the current encoder (AAC, MP3, AIFF, WAV, etc.). Parameters: iEncoder An IITEncoder object corresponding to the new encoder. Any ideas? Similar TutorialsI'm not sure I phrased the question properly and it's probably easiest to show what I'm trying to get. Basically, I want to find all the properties(?) available for a single track object in iTunes. For example, this is how I access what's stored as the Album and Artist for a track: Code: var myTracks = myPlaylists(1).Tracks; alert(myTracks(1).Album); alert(myTracks(1).Artist); There are a ton of properties (like Album and Artist), but I don't know what they all are, so I was trying to list them like this, but it doesn't work: Code: for(var key in myTracks(1)) alert(key); It's probably obvious why this doesn't work, but does anyone know how to get this list? Thanks for any help! Hello all, This is my first post here, so I apologize if I didn't format this correctly. I am trying to figure out where I went wrong in my code. The objective is to display all lines of the song using a switch statement. I thought I had my head wrapped around it, but apparently not. Would anyone mind pointing me in the right direction, or telling me what I did wrong here? I would be greatly appreciative! Thank you for your consideration folks.

I'm trynna make a website, its gonna be like, a game making website I plan to keep it as simple as possible for now, but once I get better at it.. anyways, I'm trying to figure out how I would do things such as: click, drag and drop right click, select something and make it appear on screen make something happen on keydown events 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, 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?. 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 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 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 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? 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 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 everyone, can someone please help me to find a way to rewrite this code function evenorodd( form ) { var x = new Number( form.x.value ); if( isNaN( x ) || x == "" ) { alert( "Not a number or no value entered" ); return ""; } for( var i = 0; i <= x; i++ ) ( i % 2 == 0 ) ? alert( i + " is even!" ) : alert( i + " is odd!" ); } the purpose is to show an alert box with a odd or even number Thanks in advanced! 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. "http://192.168.1.68/state.xml?relayState=2" What i would love to do is be able to add a book mark which once selected it fires off the above string and closes the window without a prompt, is this possible??? i have spent hours and hours and seem to be going nowhere. Thanks for all your help Daniel Hey everyone, could anyone help me with this code please? Code: <script language ="javascript">
function ageCalculator()
{
var day = parseInt(document.forms[0].inputdate.value);
var month = (parseInt(document.forms[0].inputmonth.value)-1);
//this is because javascript thinks of january as month 0, so we need to minus the
input month to work e.g december in javascript is month 11.
var year = parseInt(document.forms[0].inputyear.value);
var year;
var yourage;
var date = new Date();
thisday = now.getDate();
thismonth = (now.getMonth());
thisyear = (now.getFullYear());

{yourage = year}
else {yourage = year + 1}

Hi everyone, I'm trying to generate a drop down list using a supplied xml form with an xsl sheet. 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? |
