GetElementByName Not A Function Error
Mar 6, 2006
I have a function that I am working with on onload of the body.
RIght now I don't think the function is important, I am just trying to call it and pass it the name of the field I need it to use and it is giving me an error.
Here is my function call in the body tag and the quotes are escaped because the html is set in a local var so...
onLoad="d.updateOptions(document.employees.getElementByName('company'), 'dept');"
I have also tried leaving the form name out
onLoad="d.updateOptions(document.getElementByName('company'), 'dept');"
The error I am getting is Error: document.getElementByName is not a function
I thought this was how you used this. Can someone enlighten me as to what is wrong with this please?

Is there a way to reference a table cell in a table that will have X amount of rows?I want to use javascript preferably... The only methods I know of are "getElementById" and "getElementByName" - Problem is, since the cells are only known once the page is run, it is impossible to hardcode an Id OR a name before hand.

I'm trying to "progressively enhance" one of my surveys using javascript. Basically, I have rating scales that make use of radio buttons as each point on the scale. Each radio button occupies its own cell in a table. I wrote some functions that will highlight cells on mouseover in a color corresponding to its position on the scale (e.g. the lowest point is red, the midpoint is yellow, the highest point is green). When a radio button is clicked, the background of the button's cell and preceding cells in the same row will be colored accordingly. The functions are working well in FireFox and Chrome (I just have to add a few lines using the addEvent function to make it compatible with IE).
The effect looks a lot nicer when I add a function that makes the visibility of the radio buttons hidden.
However, I want to make sure that there is a fallback option in case the functions that color the cells don't work for whatever reason. I would not want the radio buttons hidden in this case.
Is there a method whereby I can call the "hideRadiobuttons" function only if the other functions are successfully executed?

Here's where I'm having an issue: [url]
It returns an error of "Error: ca is null" from this function:
Code:
The thing is that it will return a "null error" for whichever height I try to set first. I mean, if I swap the first two items:
Code:
It will return "Error: cb is null".

I have a string that is a latitude and longitude pair separated by a comma. I'm trying to separate the 2 parts of the string into separate variables, but for whatever reason, the "split()" function won't work in my code. Everywhere I've looked online says to use "split()" and my syntax seems correct,[code]When I try to run the page, I get this error in firefox:Error: latlong.split is not a function.

Just after upgrading from v1.4.3 to v1.4.4 I started receiving this javascript error on the console, but apart from the update, I didn't do any code modifications. If I follow the console link, it takes me to this point in the source:

with the line in red marked as the error source. What could it be causing the error?

I have a function which is called twice. It allows the elements of an array to be set to a different color, successively:
function ln8 (arrayA,color,current) {
var arrayB=(typeof arrayA == 'string')? arrayA.split(',') : arrayA;
var line = document.getElementById(arrayB[current]);

I am trying to code a reusable error handling function for my JavaScript objects. I thought is would be possible to display the name of the function. So this way, when an error occurs, I can display the error along with the name of the function the error occurred in. Is it possible to display the name of the function from within the function?
These examples do not work but I did try them.
<html>
<head>
<script language="JavaScript">
function display()
{
alert( this.toString() );
alert( this.name );
alert( this );
}
</script>
</head>
<body>
<a href="javascript: display();">Display</a>
</body>
</html>

Everything works fine with Opera and IE, but not with Mozilla 1.7.3 and
Firefox 1.0 PR. When I call a function previously defined inside another
function I've got "function is not defined". Why?

HI! I keep on getting this error and I have tried different things but I am
not sure how to send the expiring date.
The error that I am getting in Firefox 1.5 is
"Error: expires.toGMTString is not a function"
----------------------------------------------------
I have this in a .js file and in the head section.
function Set_Cookie(name,value,expires,path,domain,secure) {
document.cookie = name + "=" +escape(value) +
( (expires) ? ";expires=" + expires.toGMTString() : "") +
( (path) ? ";path=" + path : "") +
( (domain) ? ";domain=" + domain : "") +
( (secure) ? ";secure" : "");
}
I am calling it like this.
<script type="text/javascript">
Set_Cookie("checkpopupwarning", "1", "Thu, 2 Aug 2001 20:47:11 UTC", "/");
</script>

Using a while loop in a function, I am trying to test an input character against a stored string of characters. I want the function to return the input character only if it is not in the stored string of characters. The code I've prepared is as follows:
<SCRIPT language = "JavaScript">
var storedLetters = 'sideways';
function requestLetters(aString)
{
var validLetter ='';
[Code]...
The code works fine if I remove it from the function wrapper but if the function is called I keep getting an error message that the variable validLetter is not defined. :confused: Can anyone see why this is the case?

I have written the following javascript code which makes a simple calculation and writes between the <span> tags using Inner HTML
My code is:
Code:
<html><head>
<script type="text/javascript">
function hesapla() {
kredimiktari = document.hesapla.miktar.value
kredivadesi = document.hesapla.vade.value;
faiz = document.hesapla.faiz.value;
ayliktaksit1 = (kredimiktari * faiz) / kredivadesi;
geriodeme1 = kredimiktari * faiz;
document.getElementById('ayliktaksit').innerHTML = "<strong>Taksit / Ay :</strong>" + ayliktaksit1;
document.getElementById('geriodeme').innerHTML = "<strong>Taksit / Ay :</strong>" + geriodeme1;}
</script></head><body>
<form name="hesapla">
<input type="text" name="miktar" value="Kredi Miktarı" onfocus = "if (this.value == 'Kredi Miktarı') this.value = '';" onblur = "if (this.value == '') this.value = 'Kredi Miktarı';" />
<input type="text" name="vade" value="Kredi Vadesi" onfocus = "if (this.value == 'Kredi Vadesi') this.value = '';" onblur = "if (this.value == '') this.value = 'Kredi Vadesi';" />
<input type="text" name="faiz" value="Faiz Oranı" onfocus = "if (this.value == 'Faiz Oranı') this.value = '';" onblur = "if (this.value == '') this.value = 'Faiz Oranı';" />
<div id="gosterim"><span id="ayliktaksit"></span><span id="geriodeme"></span></div>
<input type='button' value='Hesapla' onClick='hesapla()'><br><br>
<img src="images/dot2.png" width="180" height="2" alt="dot"/>
</form></body></html>
I am really confused as similar code on Tizag web site works fine.
Code:
<script type="text/javascript">
function changeText(){
document.getElementById('boldStuff').innerHTML = 'Fred Flinstone';
}</script>
<p>Welcome to the site <b id='boldStuff'>dude</b> </p>
<input type='button' onclick='changeText()' value='Change Text'/>

I'm getting an error message that says that my function is null or undefined. I figure it' something simple, like maybe a ( instead of {, but I can't seem to find it.
Here's the script from the header:
Code:
<script type="text/javascript">
var time = new Date();
var dayNight = time.getHours();
function displayImage() {
if (dayNight >= 9 && dayNight <= 14) { .....
And from the body:
Code:
<body onload="displayImage()">
<div>
<img id="highlights" src="" alt=""/>
</div>
</body>

New to working with javascript and I've come up with a function. I have a form with a dropdown and input field:
<form>
<select name="warranty" id="warranty" onChange="doadate()">
<option value="Select">Select</option>
<option value="In Warranty">In Warranty</option>
<option value="Out of Warranty">Out of Warranty</option>
<option value="DOA" selected>DOA</option>
</select>
<input name="doadate" type="text" id="doadate" value="<? echo $doadate; ?>"
size="20" readonly>
</form>
I need the input field to be disabled unless DOA is selected in the select form element. I've started on page load with document.form1.doadate.disabled=true. Then I've put an onChange handler in the select to call the function below:
<script type="text/javascript">
function doadate(){
val = document.form1.warranty.value;
if(val=='DOA'){
document.form1.doadate.disabled=false;
} else{
document.form1.doadate.disabled=true;
}}
</script>
But it's not working, it stays disabled after load even when the DOA is selected in the drop down form field.
