Writing A ToFixed Function
Jul 20, 2007
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 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'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>

Is there a way to write a custom tweening function, preferably with easing, without the use of the build in animate() function?In Javascript, it's possible to do this with an interval, but I haven't been successful in finding something similar for jquery

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.

When I used toFixed() method on a number, I thought that this method round a number to a specified approximation, but I got a surprising result, the number became string! 15.23689.toFixed(2) ==> "15.24". So does it convert the number into string?

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.

i've been reading up on access to the dom via js (i'm new to this dom
stuff)
i understand tutorials and info such as
http://developer.mozilla.org/en/doc...t.createElement
my problem: i'd like js to create the code for a stylesheet in the head
of the docuement!
i'm not sure how do do this (or if it can be done)
can i create the following...
<link rel="stylesheet" type="text/css"
href="mystyle.css" />
OR
<style type="text/css">
hr {color: sienna}
p {margin-left: 20px}
body {background-image: url("images/back40.gif")}
</style>
using the dom or anything else in js alone?...or am i fighting a losing
battle.
(what i really want at the end of the day is to detect the browser and
use a css file according to that file, either with js or php)...

I have an existing page that dynamically creates data in a popup
window. I am trying to change it to use an iFrame. Is the following
code valid:
The iFrame is as follows
<iframe src="theframe.html" name="theframe"></iframe>
"theframe.html" is an existing file initially with instructions.
In a script I do
thewindow=window.open("","theframe");
thewindow.document.open();
thewindow.document.write("Some Requested Data");
thewindow.document.close();
This is done multiple times depending on what the user requests each
time. Sometimes this works and sometimes it doesn't. I'm probably doing
someing very wrong but I don't know where to look for reference.
I'm not really opening a window so there must be another way to do it.
What is the best way to write to an iFrame or should I not even try?

I have a function that generates the code I want from form input.
Beneath the form I want to create a div tag and write out the results from the form input.
How would I go about doing this?
How would I go about passing the results from the function (e.g. function newCode() {.......(code)... var scroll = X }
Then I want to write out X in a div tag?

I'm trying to write a Tic-Tac-Toe program in JavaScript. I have an array containing the state of the grid. For some reason when I update the "O" for the computer's move, it doesn't show this in the updated grid. I don't understand why.[URL].. I'm brand new to JavaScript, and sometimes I accidentally use syntax from C++ or PHP when writing, so it could be something as simple as that. I just can't figure it out.
