JavaScript - Text Box Duplicated Numbers Error Does Not Work 100%

hi please help,
i want to select numbers from a list box and add it to a text box with comma separated. my java script code does not work into browser but work fine into eclipse jsp view.

Code:

		function passingNumbersToTextArea(numToCall,allNum)
		{
			var numFromList=document.getElementById(allNum);
			var numToTextArea=document.getElementById(numToCall);
			if(numToTextArea.value.search(numFromList.value)!=-1)//if duplicate Number is exist
			{
				alert("Duplicate Number Can not be added :");
				return false;
			}
			else 
			{
				if(numToTextArea.value.length!=0)
				{
				// If textarea has value than it added another value with comma seperated 
					numToTextArea.value=numToTextArea.value+','+numFromList.value;
					return false;
				}	
				else
				{				 
					numToTextArea.value=numFromList.value;
					return false;
				}
			}	
 		}


jsp code 

<h:inputTextarea cols="10" rows="4" id="numberToCall" required="true"
value="#{conferenceCall.numberToCall}" styleClass="form_input_box" />
<h:selectOneListbox styleClass="form_selectmenu" id="allNumbers" size="5" onclick="passingNumbersToTextArea('numberToCall','allNumbers');">
<f:selectItem itemValue="9971701077" itemLabel="Sharad : 9971701077"/>
<f:selectItem itemValue="9990102381" itemLabel="Saurabh : 9990102381"/>							
</h:selectOneListbox>

javascript debugger shows error

Hi

I am trying to use stoutlabs content slider on my website.

I have a dummy set up here www.mattbbell.com

Instead of the numbered navigation i want to have text like home, bio, contact etc

The demo can be download here http://stoutlabs.com/demos/class_sli..._slider_v2.zip

with all files necessary to make the dummy website you see there...

From what i can tell I have to edit the sl_slider_new.js file and make it call a list of divs that i name home, bio, contact

I think this is the section i need to edit but i don't know much about javascript....

Code:

// -- Number nav setup
			if(self.options.numNavActive == true){
				//create numbered navigation boxes, and insert into the 'num_nav' ul)
				var numItem = new Element('li', {id: 'num'+i});
				var numLink = new Element('a', {
					'class': 'numbtn',
					'html': (i+1)
				});
				numItem.adopt(numLink);
				self.options.numNavHolder.adopt(numItem);
				self.numNav.push(numLink);
				numLink.set('morph', {duration: 100, transition: Fx.Transitions.linear, link: 'ignore'});
				
				numLink.addEvents({
					'click' : function(){
						self.numPress(i);
					},
					'mouseenter' : function() {
						this.setStyle('cursor', 'pointer');
					}
				});
				
				//set initial number to active state
				if(i == self.options.itemNum){
					var initNum = self.numNav[i];
					initNum.addClass('active');
				}
			}
			//end if num nav 'active'
		
		 });
	
	},

thanks!

I have a database script that returns dates in the following format:

yyyy-mm-dd

I have been using the following code to change this format to dd-mm-yyyy:

Code:

<script type="text/javascript">
var myString = "[[date]]";
var mySplitResult = myString.split("-");document.write(mySplitResult[2] + "/" + mySplitResult[1] + "/" + mySplitResult[0] );
</script>

However, I now want to display the date in text format, e.g. 01-08-2009 would be displayed as 01 August 2009.

Could anyone please let me know how I change the script to show this format?

Many thanks in advance,
Neil

Can someone please help me generate a series of 13 digit numbers and output them to a text file. I'm really desperate here.

Thanks guys.

I'm creating a page that calculates a number depending on what value is inputted into a text field. I need to create some javascript that updates this new calculated value and outputs it next to the input field. Anytime the user changes the number, it recalculates the value. My calculation is currently being produced by PHP, however if I need to, I can create javascript as well to recalculate these numbers.

My formulas for all 4 calculations are as follows:

First: Inputted Value * 10
Second: Inputted Value * 20
Third: Inputted Value / 2
Fourth: Inputted Value * 2

Here is my code I'm working with:

PHP Code:
<?php
session_start();
$username = $_SESSION['username'];

include_once('inc/connect.php');

$credquery = mysql_query("SELECT * FROM userstats WHERE username='$username'");

$credits = $row['credits'];
$bannercredits = $row['bannercredits'];
$textcredits = $row['textcredits'];

$sitetobanner = $_POST['sitetobanner'];
$sitetotext = $_POST['sitetotext'];
$bannertotext = $_POST['bannertotext'];
$texttobanner = $_POST['texttobanner'];

if (isset($sitetobanner)){

$bannerimp = round($_POST['bannerimp']);
    if ($bannerimp > 1){
        $s = "s";
    }
    if ($bannerimp <= $credits){
        $newcredits = $credits - $bannerimp;
        $newbannercredits = $bannerimp * 10;
