Im trying to make the first ul tag in the each slideMenus[] array index values have a position of left = 0px I keep recieving this error however
____________________________________________________
Error: slideMenus[i].getElementsByTagName("ul").style is undefined

Line: 63
------------------------------------------------------------------

the script in question is in [code]. Could someone tell me if I am just making a syntax error if not ill try redoing the whole thing.










window.onload = makeMenus

var currentSlide = null
var timeID = null
leftPos = 0

function makeMenus(){
var slideMenus = new Array()
var allElems = document.getElementsByTagName("*")
var slideListArr = new Array()

for(var i=0 ; i < allElems.length ; i++){
if(allElems[i].className = "slideMenu") slideMenus.push(allElems[i])
}



for(var i=0 ; i < slideMenus.length ; i++){
slideMenus[i].onclick = showSlide;
Code:

slideMenus[i].getElementsByTagName("ul")[0].style.left = "0px";

}
document.getElementById("head").onClick = closeSlide
document.getElementById("main").onClick = closeSlide
}

function showSlide(){
var slideList = this.getElementsByTagName("ul")[0] // mess with this
if((currentSlide != null) && (currentSlide.id == slideList.id))
{closeSlide()}

else{
closeSlide();
var currentSlide = slideList;
currentSlide.style.display = "block";
timeID = setInterval('moveSlide()', 1);
}
}

function closeSlide(){
if(currentSlide){
clearInterval(timeID);
currentSlide.style.left = "0px"
currentSlide.style.display = "none";
var currentSlide = null
}
}

function moveSlide(){
var leftPos = leftPos + 5;
if(leftPos <= 220)
{currentSlide.style.left = leftPos + "px"}
else{
clearInterval(timeID);
var leftPos = 0}
}

Hi!

Can someone help me please...
thanks in advance.

Javascript
Code:

 <script type="text/javascript">
  
$allValues = new Array();
$allValues[0] = 'Choose One';
$allValues[1] = 'A1';
$allValues[2] = 'A2';
$allValues[3] = 'A3';
$allValues[4] = 'A4';
$allValues[5] = 'A5';
			
			
            function stripDupelicateValues(inElementId)
{
    // get current list of all selected values
    $selectedValues = new Array();

    for( $position in $allValues )
    {
        if( $position != 0 )
        {

            $formField = eval( 'document.crewchange.emp_' + $position );

            // preserve our selected values
            $thisSelectedValue = $formField.options[ $formField.selectedIndex ].value;
            $selectedValues[$thisSelectedValue] = true;
        }
    }


    for( $position in $allValues )
    {
        if( $position != 0 )

            // preserve our selected values
            $thisSelectedValue = $formField.options[ $formField.selectedIndex ].value;

            // wipe out the previous choices
            $formField.options.length = 0;

            // create default option
            $formField.options[0] = new Option( $allValues[0], 0 );

            for( $optionValue in $allValues )
            {
                // add each of our non selected values
                if( $selectedValues[$optionValue] != true )
                {
                    $formField.options[$formField.options.length] = new Option( $allValues[$optionValue], $optionValue );
                }
                // create the option for our selected value
                else if( $thisSelectedValue == $optionValue )
                {
                    $index = $formField.options.length;

                    if( $optionValue != 0 )
                    {
                        $formField.options[$index] = new Option( $allValues[$optionValue], $optionValue );
                        $formField.options[$index].selected = true;
                    }
                }

            }
        }
    }
}


        </script>

Html
Code:

<form action="cc2.php" method="post"  name="cc">
<select name='emp[]' id='emp_1' onChange='stripDupelicateValues(this.id)'>
<option>Choose One</option>
<option value='1'>A1</option>
<option value='2'>A2</option>
<option value='3'>A3</option>
<option value='4'>A4</option>
<option value='5'>A5</option>
</select>
</form>

Error Msg
Code:

Message: Unable to get value of the property 'options': object is null or undefined

Code:

out += (out ? rogueArray[14] : rogueArray[13]) + arrayItem + ((vanWilder[arrayItem] !== null) ? = + encodeURIComponent(vanWilder[arrayItem]) : rogueArray[13]);

There is supposedly a syntax error here on the line up until [arrayItem in Dreamweaver. Any help?

On this page
http://jimpix.co.uk/ecards/262-no-words.html

I get this Javascript error in IE6:

Code:

Line: 5
Character: 1
Code: 0
Error Message: Syntax error
URL: http://jimpix.co.uk/ecards/262-no-words.html

I'm using the DebugBar add in for IE (http://www.debugbar.com/)

The error message in DebugBar is this:
http://jimpix.co.uk/junk/error.png

And the view-source of the page is he
http://jimpix.co.uk/junk/source-code.png

I don't get the error in Firefox 3 or IE7.

I can't work out how to fix it.

Any advice would be much appreciated.

Thanks!

Can someone point where i'm going wrong? I want to evaluate the values of 'miles' to be >=0 and 'putime' to between 0 and 24 only.
Code:

<script type = "text/javascript">
	function TaxiFare() {
	// calculates taxi fare based upon miles travelled
	// and the hour of the day in military time (0-23).

	var baseFare = 2.50;
	var costPerMile = 2.00;
	var nightSurcharge = 0.50; // 8pm to 6am, every night

	var milesTravelled = Number(document.getElementById("miles").value);
	var pickupTime = Number(document.getElementById("putime").value);

	var cost = baseFare + (costPerMile * milesTravelled);

	// add the nightSurcharge to the cost if it is after
	// 10pm or before 6am
	if (pickupTime >= 22 || pickupTime < 6) {
	cost += nightSurcharge;
	}
	if((document.getElementById('miles').value>=0)&&(document.getElementById('putime').value>=0||<=24) {
	alert("Your taxi fare is $"  + cost.toFixed(2));
	}
	else{return 0;}
	}

	</script>
