I have a page that takes nodes from drupal and pulls the athletes information and renders it into a roster page via a PHP array. initially the page did not have a logical sort and basically was rendered in the order of the node creation. I added sorttable.js to the file and you could then sort based on the header. However, our head coach wanted it to be sorted onLoad by player number (first column) so I added datatable and set aasorting to 0, asc and it actually sorts the second column (name) instead of column 1. No matter which column I set it to it only sorts the name column. If I could get some advice about how to fix this I would appreciate it.

Code:

<style type="text/css">table.sortable th:not(.sorttable_sorted):not(.sorttable_sorted_reverse):not(.sorttable_nosort):after { 
    content: " \25B4\25BE" }
</style>

<script src="/jscript/sorttable.js"></script>
<script type="text/javascript">
   $(document).ready(function() {
	$('#roster').dataTable( {
		"aaSorting": [[ 0, "asc" ]]
	} );
} );</script>
       




<table width="100%" cellpadding="2" cellspacing="2" border="1" class="sortable" id="roster" style="border-bottom:1">
	<thead>
		<tr>
			<?php if( ! empty($vars['sport']->field_sport_show_number) && 1 == $vars['sport']->field_sport_show_number['und'][0]['value'] ): ?>
				<th class="style4, sortBy" style="width: 14px;"  data-sortType="numeric" id="number"><span style="font-family: Arial, Helvetica, sans-serif; font-size: small;">#</span></th>
			<?php endif; ?>

			<th class="style4" style="width: 14px;" ><span style="font-family: Arial, Helvetica, sans-serif; font-size: small;">Name</span></th>

			<?php if( ! empty($vars['sport']->field_show_class) && 1 == $vars['sport']->field_show_class['und'][0]['value'] ): ?>
				<th class="style4" style="width: 14px;"><span style="font-family: Arial, Helvetic

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.

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>

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

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

Please help me to those who can...

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 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?

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.

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 have written javascript for mouseover and click event to change the images.

Here is a URL

http://leowareit.com/imageselect/

The aim is when user click any of image, it should be selected and other should not be selected. I achieve this by changing the images. with following code

Code:

$(function() {
 $('.gender').click(function(){
    $('.gender').each(function() {
        $(this).attr('src','http://dev.trivian.com/theme/trivianV2/icon/' + $(this).attr('alt')+'_up.png');
    });
	 var src = 'http://dev.trivian.com/theme/trivianV2/icon/' + $(this).attr('alt')+'_down.png';
	 $(this).attr('src',src);	 
 });
});

And also when user do mouse over to the images, the images get changed with following code

Code:

$(function(){  
	 $('.gender').hover(function(){
		$(this).attr('src','http://dev.trivian.com/theme/trivianV2/icon/' + $(this).attr('alt')+'_down.png');
	},
	function(){
		 $(this).attr('src','http://dev.trivian.com/theme/trivianV2/icon/' + $(this).attr('alt')+'_up.png');
	});
  });

Now the problem is if I remove the mouse-hover code, the image selection is working properly with onclick, but with mouseover code, the click event get overwritten.


Any help will be appreciated. I am not that good at javascript.

Thanks
