Writing Function Output Values?
Jan 20, 2009
I've got a glitch somewhere and it's not obvious to me. Maybe someone can spot it.My problem is that the functions seem to return values but don't display them like they should. I'm testing returned values with a function called sayvalue(item). But when I test "DelTimeCode" the function returns "[Object]". I don't understand. I get returned values from DelTime and DelTitle.My approach is to select a radio button option, return a delivery title and a delivery price from the appropriate functions then write the information. I think I'm close. Any suggestions or observations of an error in my code?I have the following VARIABLES and FUNCTIONS:
<head>
var AmtSV;
var DelTimeCode="";

I want to use document.write to output the values of an array. If the array is too long, it totally ignores the width of the container div. How do I get the values to word-wrap when they get to the end of the container?
I've searched on this forum, and also googled for the answer but can't find a solution. I'm still fairly new to Javascript.

I'm not that familiar with javascript, and I am trying to write a
toFixed function.
The function takes two arguments, the number and the number of decimal
places we're interested in.
If the number of decimal places is negative, it's interpreted as the
number of significant digits.
Thus:
toFix(12345.6789,2) -12345.67
toFix(12345.6789,0) -12345
toFix(12345.6789,-2) -12000
I've hacked up a solution that so far works on all tested browsers for
the first 2 cases.
It's the last one I'm having trouble with... How do I get only the
significant digits?
It has to work for all of the following cases:
toFix(12345.6789,-2) -12000
toFix(12345.6789,-5) -12345
toFix(12345.6789,-7) -12345.67

I've been using the document.write function to loop through some xml and print the data within a HTMl table. I thought it would be useful to add a hyperlink to the table row, so I thought the best way to do this would to create a function (called popup), which takes an id as a parameter.
The problem with this, is that when writeing using the onClick, the speech marks seem to all get messed up.
Code:
onclick='popup('"+mailID+"')'
I'm 99% sure it's just the speech marks, i'm just not sure of the right combination, and it's doing my head in
If someone could even point me in the right direction, even the proper name as to what this is called would be great, as googleing it is proving to be a nightmare!
Here's the whole section of code if it's more useful:
Code:
var mailID = x[i].getElementsByTagName("mailid")[0].childNodes[0].nodeValue;
if (r == "unread") { //email is unread
document.write("<tr onclick='popup('"+mailID+"')' title='test'>"); } else { //else is read, so add colour

If you specify arguments when writing a function should you still declare the argument variable inside the function?

For example I have a link that I want to when I click on it, It writes some words after the link. I have written a code but it does not work as I want and it clears all the page and writes the words. I don't want to clear the page and write just words, I want to add words after the link.
Here is my code:
HTML Code:
<script type="text/javascript">
function a() {document.writeln('aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa');}
</script>
<a name="aaa" href="javascript:void()" onclick="a()">Click on me!</a>

I'm trying to return all the permutations of a given string, so I wrote the following recursive function:
The problem is, I'm not getting all the permutations, and I don't know why.
For example, if string="bindle", the output I get is:
And then the function stops.

How would you go about writing a function that returns a string that outputs a branched bulleted list using <ul> and <li> tags of all the html elements in a page? The html elements don't all have id's or names, so I cannot reference them directly. I would like to do it recursively so that I can grab all the elements, not just those two or three levels deep.

I'm working on a project in which I parse the XML and I get the element names.
So far everything is ok.
Also, I would get a variable increment that I create in the function and I want to find out of it.
Unfortunately, I can not recover.
Here is an example of my script:
// start
// "i" is my increment variable
var i = 0;
$(this).find('foo').each(function(i){ // run correctly x time
i = i++;
[Code]....
How do I find my variable "i" to the output of my loop?

I am trying to taking this embedded script
Code:
<SCRIPT LANGUAGE="JavaScript">
<!-- Begin
var strDay;
if ((now.getDate() == 1) || (now.getDate() != 11) && (now.getDate() % 10 == 1)) // Correction for 11th and 1st/21st/31st
strDay = "st ";
else if ((now.getDate() == 2) || (now.getDate() != 12) && (now.getDate() % 10 == 2)) // Correction for 12th and 2nd/22nd/32nd
strDay = "nd ";
else if ((now.getDate() == 3) || (now.getDate() != 13) && (now.getDate() % 10 == 3)) // Correction for 13th and 3rd/23rd/33rd
strDay = "rd ";
else
strDay = "th ";
document.write(dayName[now.getDay()] .....
// End -->
</script>
and turn it into a function called time.
XHTML Source
Code:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "[URL]">
<html xmlns="[URL]" xml:lang="en">

<strong><script type="text/javascript">time()</script></strong>

Javascript Source
Code:
function time() {
var strDay;
if ((now.getDate() == 1) || (now.getDate() != 11) && (now.getDate() % 10 == 1)) // Correction for 11th and 1st/21st/31st
strDay = "st ";
else if ((now.getDate() == 2) || (now.getDate() != 12) && (now.getDate() % 10 == 2)) // Correction for 12th and 2nd/22nd/32nd
strDay = "nd "; .....
But when I do the out put returns nothing. Why this might be. I initially thought that I had the formattingsyntax wrong for the function it self but this doesn't seem to be. [URL]

What's supposed to happen is when the program is run the user clicks on "Select your Numbers!" their then asked for 5 numbers which they input and then the numbers are checked by a function called �isAlreadySelected� for duplicates and if there is an alert is shown. When 5 numbers are entered correctly then they are shown by a window.alert.
Its done in to 2 functions
When I run the below code I'm prompted for the 5 numbers but it isn't checking for duplicates and my selection is undefined.

I'm fairly new to writing script and so can only assume I have got something incorrect because the 'ages' are failing to change by -1 when the month and day is greater than the current date.
function currentAge(value){
var theDOB = value;
var theDOB = theDOB.split('/');
var DOBday = theDOB[0];
var DOBmonth = theDOB[1];
var DOByear = theDOB[2];
var todaysDate = new Date()
var yr = todaysDate.getFullYear();
var mth = todaysDate.getMonth() +1;
var dayy = todaysDate.getDate() +1;
var theAge = (yr -DOByear);
var yearBefore = (theAge -1);
if (mth <= DOBmonth && dayy < DOBday) {
return yearBefore;
}
else {
return theAge;
}}

outputting the results from a javascript search function onto a new page. Right now I am using a javascript search script on 7 pages and it works but the results overwrite the current page that the search was initiated from. I would like it to open a new page and print out into a specific area. Im not really proficient in js, tho I know enough to get by. since ive been grinding my gears at work trying to get this to display right. I'll post the code tomorrow morning when I get to work so you can see the function.

I'm working on some code and am running into brick walls. I'm trying
to write out Javascript with Javascript and I've read the clj Meta FAQ
and didn't see the answer, read many similar posts (with no luck
though), and searched through the IRT.ORG Faqs
(www.irt.org/script/script.htm).
The Javascript is designed to open an popup window and then inside that
window call another script which will resize that window. There may be
another way around this but the reason I tried this approach initially
was that I wanted to call the onload handler in the popup window to
resize the image only after the image had completely loaded. I've had
some code in the primary Javascript file (showimage.js) before that
works if the image has been cached but on the first load, it doesn't
resize properly which tells me it is probably because it is trying to
resize the window based on the image size but it isn't completely known
at that point. So I removed that code and tried placing the resizing
code in the second Javascript file (resizewindow.js). BTW I've tried
other code to open a popup image and automatically size it ie Q1443 at
irt.org but that doesn't do exactly what we need.
Even if there is another way to do this with one file, I still want to
figure out why this isn't working in case I run into it in the future.
I thought what I would need to do to use document.writeln to write
Javascript would be to escape any special characters and to break
apart the script tag ie
document.writeln('</SCRIPT>');
would become
document.writeln('</SCR' + 'IPT>');
I have a HTML page and 2 Javascript files. All files are in the same
directory and have permissions set correctly.
Here are the 3 files (keep in mind wordwrap has jacked up the
formatting):
index.html
----------
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title>Test</title>
<SCRIPT type="text/javascript" LANGUAGE="JavaScript1.1"
SRC="showimage.js">
</SCRIPT>
</head>
<body>
Click the house<BR>
<A ONCLICK="newWindow1('house1.jpg','Nice House')"><IMG
SRC="house1thumb.jpg"></A>
</body>
</html>
showimage.js
------------
function newWindow1(pic,sitename)
{
picWindow=window.open('','','width=25,height=25,sc rollbars=1,resizable=1');
picWindow.document.writeln('<html> <head>');
picWindow.document.writeln('<SCR' + 'IPT type="text/javascript"
LANGUAGE="JavaScript1.1" SRC="resizewindow.js"></SCR' + 'IPT>');
picWindow.document.writeln('</head>');
picWindow.document.writeln('<body onload="resizewindow();">');
picWindow.document.writeln('<img src=' + pic + '>');
picWindow.document.writeln('</body> </html>');
picWindow.document.close();
}
resizewindow.js
---------------
function resizewindow()
{
// Do resizing here.
// Right now this isn't being executed
alert("resizing window");
}
Can anyone provide some pointers as to why this javascript is failing?
I'm using IE6 on Win2k and when I click on the image to open the popup
window, it does open the window but it is white with no content and the
system immediately goes from about 4% CPU usage to 100% and
consistently stays there until I kill that window with the task
manager.
