DisplayName() Function Keeps Coming Up As Undefined?
May 6, 2011
I have a single page with a single form, but I have split the form into 3 divs for styling purposes. I have some java script that is supposed to pull values from the text fields, and put them in a selct box using 'document.forms[0].name.value', but nothing is happening. I am wondering if having the form split into to divs is causing the JS to not be able to find the fields, using the forms array? Here is the form portion of the html code:
<form name="roster" action="">
<div id="left">
<dl>
<dt>Team Name</dt>
[Code].....

I am trying to use my date Object function to get the date from the comp but my variables in my function are coming up undefined.
Here is my function:
function displayTime() {
var currentTime, hour, minute, second, range, m, s
currentTime = new Date()
var hourInt = currentTime.getHours()
var minuteInt = currentTime.getMinutes()
var secondInt = currentTime.getSeconds()
if (hourInt > 12) {
range = "PM"
hourInt -= 12
} else {
range = "AM"
}
hour = String(hourInt)
if (minuteInt < 10) {
m = String(0) + String(minuteInt)
} minute = m
if (secondInt < 10) {
s = String(0) + String(secondInt)
} second = s
document.timeForm.timeBox.value = hour + ":" + minute + ":" + second + " " + range
alert(hour + ":" + minute + ":" + second + " " + range)

I've boiled down my code to the essence of the problem; a variable which serves as a parameter to a function keeps coming up as 'undefined'. The code is quite simple:
....
<head>
<title>Yearly Calendar</title>
[code]....

I have several divs called 'profile', 'codesamples', 'artportfolio' and 'resume' which are hidden. I also have a visible div called 'bodytext' which is visible. When you click one of the links on my page, the function ClickButton is supposed to run, and send the information contained in one of the hidden divs into my visible 'bodytext' div. Instead, I get 'undefined' when I click one of the buttons.

Here is a clip of code from a script project im working on. Now my document.getElementsByTagName is returning a "undefined" value.
<a href="[URL]" style="text-decoration: none; color: #EDDBAF; font-size: 16px;">
<center style="margin-left: 10px; margin-right: 10px;">
<font style="color: #EDDBAF; font-size: 16px;" id="title"></font>
</center></a>
<li id="name"><a http="[URL]" style="color: blue;">John Doe</a></li>
<script type="text/javascript">
var pname = document.getElementById('name').getElementsByTagName('a');
Now if I remove the ".getElementsByTagName('a')" it will actually work, but it also includes the <a> tag thats within the <li> tag, which I don't want.
document.getElementById('title').innerHTML=pname.innerHTML;
</script>

The following coding works in Konqueror 3.5.10 on Ubuntu 8.04.3 LTS but not on Firefox 3.0.10 Linux/3.5.7 XP, Opera 10.10 Linux or IE8 XP.I can't see why but it may be to do with the recursion (showtable calls onclick calls addit which calls showtable).Somehow it is not seeing the addit routine the second time round.It is meant just to add a line. Eventually it needs to be a complex table but this is for illustration. There are other ways to solve this but this would be the simplest - if it worked!What happens is that one line is added OK but then it chokes. This is what makes me think it is the recursion but I can't see otherwise how to make it write the updated text. I realise I should have a document.close() in it as well and I have tried adding <![CDATA[ ... ]]> as well.Other than in Konqueror, it gives an error message saying object not found (in IE8) or more explicitly:[code]

Suppose we have following javascript codes: Case 1.
var foo = function (){
var x = "hello";
var bar = function () {
alert(x);
} return bar;
} var bar_ref= foo();
document.write(bar_ref()); // it pops up "hello" and print-outs "undefined".
If we modified above code slightly, shown as follow: Case 2.
var foo = function (){
var x = "hello";
var bar = function () {
alert(x);
} return bar();
} var bar_ref= foo();
document.write(bar_ref()); // it only pops up "hello".
As you can see, Case 2 modified the return value from "return bar" to "return bar()," which won't cause the "undefined" output. To me, it looks like when the JS interpreter executes the line "bar_ref();" it triggers the execution of function "foo", besides both "return bar" and "return bar()" do the same job which is to execute function body of "bar".
The only difference is that after the execution of function bar, its function body does not exist anymore, so when the interpreter executes the line "return bar;" it follows the function identifier "bar" and ends up with "undefined". This is why the Case 1 gives us "undefined", but I am not quite clear about why the Case 2 can trace down to the function body of "bar". Do you have any ideas about such difference outputs?

Part 1 of this post I have tested the file i am working on firebug and it's html output result as:undefined can anybody and i have wondered what can be done to define?
HTML Code:
<td>
<ul id="Torpedo" class="undefined">
<li class="one">
<a title="1 Star" href="javascript:RateItem('Torpedo', 1);">1</a>
</li>
[Code]...
So the problem is in the connection from the rating.class.php to rating.js or inside the rating.js where there is not reference to the rated CSS class which define stage 3 in the illustration above. as I said it is suppose to go from stage 1 to stage 3 and define immediately instead with the rated css class instead of going from stage 1 to stage2 to stage 3
there is another file used in this system and it is a javascript file call prototype.js and it seem to be a general file used by most java scripts to pull out functions from there.

I have been trying to figure this out for a few days now and have finally come to the point where I think I got it but may just need a little push to get what I want.
Heres the situation:
I have this function that uses ajax to access a database and returns the results in the responseText. That part is working fine, I have confirmed that the responseText contains the information that I need
**************code*****************************************
//new ajax already created and assigned to the variable xmlhttp//
var response_recieved = "some data";
function get_answer(Table_Name, Field_Name, Data_Type) {
[Code]....
As evidence by my posting, this is not working correctly. The variable response_recieved is coming up undefined outside of the callback function assigned to the onreadystatechangeproperty.
Based on the information that I have gathered online from various forums, I believe this issue has to deal with a problem with closure in the callback function assigned to onreadystatechange property. I don't think it has any. Based on the fact that there is no anonymous function in that function. But my problem is that the call back function is anonymous itself... I think???
get the variable response_recieved to survive outside of this function.

I'm just starting out with Javascript as a development language and this will probably be a relatively simple problem for someone to solve for me.
I am trying to access a variable (this.bodyEl.innerHTML) from within a function but get an error message indicating that it is "undefined". I know that it is a valid variable because I call it elsewhere outside of the inner function itself.
I'm sure this is just a scope issue, but I'd welcome any suggestions on how to solve it with an explanation of where I've gone wrong if you have the time.

I have a function where in I call another function that assigns a value to a var. code...
For some reason my code below is returning 'undefined'. But when I place an alert(); before the 'return' it shows the correct value. However when I place an alert(); to show the var that is set to what the function returns it says 'undefined'.
Firebug throws no errors. I am using a little bit of jQuery.

Here's the problem: I have several hidden divs containing information. When you click on a link, javascript executes which is supposed to move the appropriate info from one of the hidden divs into the visible 'body' div. The javascript isn't working, though, and I'm getting 'undefined' instead

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>

When I run the following code, the .Length function returns "undefined."
var strTest = 'test';
alert(strTest.Length);
Using the typeof function, I know that JS is treating the variable as a string.
