Writing A ToFixed Function
Jul 20, 2007I'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
Need To Escape Parentheses In Script Parameter String???
Jul 20, 2005I'm passing a parameter to a script, which sometimes fails.
However, I discovered that the ones failing had parentheses within the
text string, e.g., "Step: Press the (0) on the console."
I've learned how to escape apostrophes, but how do I do so for parens?
Is it ( ? Also, where ' was the xml entity for apostrophe,
would someone know the one for left and right parens? Can't find that
either...not having much luck today with my searches.
Onclick AJAX :: Where To Add The Open And Closing Parentheses?

I know how to use buttons to call JS functions but I'm not sure where to add the open and closing parentheses with this AJAX...I've tried encasing different parts, but to no avail.So guessing I have to do something different here? I'm not sure, really new to this.And yes I've tried searching, again it's very specific and a bit vague.

Writing Function Output Values?
Jan 20, 2009I'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;

Use Of Speech Marks When Writing Function To HTML
Jan 13, 2009I'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

Writeln Function - Writing Some Words After Link
Aug 8, 2011For 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.

My Function Works Only If Alert Function Exists Inside It?
Jan 17, 2011I have what I think is a strange issue but others may see something I am missing.I am using AJAX functionality to process a php script on a server and then place the output of the script into a div element.Here is the code snippet
Code:
function doWork13(typeCode,colorBlockName,objectCategory,imgID){
httpObject = getHTTPObject();
if (httpObject != null) {[code]....
This code shown here works perfectly BUT....I do not want the alert message to be there. When I remove that line of code the script fails to function. There is no error just nothing happens.The function is to replace one image with another and the variable in question is simply the ID tag of the particular image being modified.As I said it works with the alert but does not with out, could it be a timing issue in that the alert gives enough time for the if statement in the setOutput13 function become TRUE
