?: In Regular Expression
Feb 21, 2006I have seen lot of reg. expession with ?:
For dummy eg
(((XXX)ddd)ff)
The above expression is modified as
(?:(?:(XXX)ddd)ff)
Although both the above expr. gives same result. (RegExp.match() gives
same o/p), most of the places , i have seen second option.
Yes, but different matches r shown (using RegExp.exec())
Is the second expr. most efficient or in particular scenarios?
Any comments???
Reg Expression For Currency
May 20, 2006I need a regular expression to format U.S. currency as 1,215.25 (commas and decimals)...if it is not already in that format. It should also allow a '-' sign as the first character for negative numbers. I have looked in the FAQ and through this group, plus the net and cannot seem to find the right example.
Any pointers or solutions appreciated. Thanks. I found the belowposted in this group:
<script type="text/javascript">
var RgX = /^$(d{1,3}(,d{3})*|(d+))(.d{2})?$/
function NewComma(Q) { Q = String(Q)
return (Q == (Q=Q.replace(RgX, "$1$2,$3"))) ? Q : NewComma(Q)
}
function setFormat(elm){
var frmCurr= NewComma(elm);
alert(frmCurr);
}
setFormat(121525);
</script>
JS Does Not Execute The Expression?
Mar 25, 2011I have the following function:
function sonKare(sayac, oteki) {
var vertical, horizontal = hangiYataySira(sayac, oteki), j, k,
l, m, united, tekRakam, actualV = [], actualH = [],
numaralar = [1, 2, 3, 4, 5, 6, 7, 8, 9], olmayanlar = [];
[Code].....
This is a recursive function. As stated above there is a line which does not work for the second time. What I mean is, it works perfect for the first time and after function calls itself, it doesn't work. Javascript does execute the line above it but just disregards that document.form1.buton.click(); line. I use Firebug for debugging and I checked it many times, when that expression needs to be executed for the second time, JavaScript just ignores it and immediately goes at the end of the function... I just can't figure out why JS does such a thing?
How Do I Tweak This Javascript Expression?
Jul 23, 2005I have got a bookmarklet for use with Opera which highlights all
occurrences of some text in the displayed page. I find it very
useful.
Sometimes I need to use two or three different colours for different
keywords I want highlighting on the same page. I have done this by
changing the original word 'yellow' for other javascript colour
words.
I know next to nothig about javascript. So I would ask if anyone
knows how I can tweak this javascript bookmarklet code (see below) in
two sepearte ways:
(1) So that I can select a color from a list. This may be as simple
as changing the caption to say "enter 1 for lime, 2 for yellow," etc.
or it might be cleverer.
(2) This is mutually exclusive with (1). In this case the
javascript would prompt me to enter a javascript colour keyword (like
"yellow" or colour code like "FF00FF").....
Regular Expression Problems
Jun 28, 2006At the moment my code is like:
function telValid(inString) {
var regexp = /^[0-9 +()]+$/;
return (inString.match(regexp,''));

this works ok, but wont allow - (Dashes) which i need..

var regexp = /^[0-9 +-()]+$/;
return (inString.match(regexp,''));
}

Regular Expression To Get The File Name From A URL?
Feb 5, 2009regular express to get the file name from a URL?
It has to be flexible in that the extension can be either 4, 5, or 6 chars (.php, .html, .shtml for example) and needs to cater for and whether querystring parameters exist too.
So, both
[URL]
and
[URL]
The regex should return newthread for both.

Dec 30, 2004When Internet Explorer 5.01 for Windows hits the regular expression:

Aug 16, 2002I have been looking and looking to no avail.
IE has had, since IE4, the use of:
expression( [function or script expression])

Does Netscape v6+ and/or mozilla have anything of the sort?
Code:
<style type="text/css">
div{position:absolute;
top:expression((document.documentElement.offsetHeight * 0.15) + 'px');}

Comma Delimited Regular Expression
Dec 7, 2006I need a regular expression that will validate a double quote comma
delimited list where the odd entries are numeric and the even are
alphabetical. Each pair must also be on a separate line. For example:
"1","Peter"
"2","Paul"
"3","Mary"
I've used the following expression to validate comma delimited lists, but
without the double quotes, numeric/alpha pairing and line return
restriction.
^([A-Za-z0-9]?)+([,]s?([A-Za-z0-9]?)+)*$
Regular Expression To Match Any Spaces
Oct 9, 2007Normally I can write regular expressions decently well but for some
reason I am having trouble getting this to work. I am validating form
data and need to throw an error if there are ANY spaces in the field.
abc123 is fine, abc 123 is not. Any character is fine, just not a
space.
Regular Expression To Exclude Lines?
Jul 20, 2005All I'm trying to do is delete the lines which don't contain a particular
string. Actually a filter to edit a log file. I can find and replace a thing
with null, but can't figure out how to find the lines which do not contain
the thing.
Going further, I want to generalize and use a JavaScript variable containing
the decision string, but first I need to worry about the not-within-a-line
problem.

View 2 Replies View RelatedApply A Style Expression During Runtime?
Feb 10, 2009I need to set the position of an element to fixed using JavaScript at runtime.
Sadly, IE6 does not know this value, so I want to use the following workaround:
Instead of setting the position to fixed, I set it to absolute for IE6, and the top value needs to be the following expression:
Code:
top: expression(0+((e=document.documentElement.scrollTop)?e:document.body.scrollTop)+'px');
Sadly I have no idea on how to apply this expression to myFixedObj.style.top! I tried it using
Code:
myFixedObj.style.top=expression(0+((e=document.documentElement.scrollTop)?e:document.body.scrollTop) +'px');
and
Code:
myFixedObj.style.top="expression(0+((e=document.documentElement.scrollTop)?e:document.body.scrollTop)+'px')";

Regular Expression For US Phone Numbers?
Apr 30, 2009Here is the form in question: spraytechDOTcom/download_form.asp I am so close to getting this to work the way that I want, but here is what I am having an issue with: I cannot seem to make it look for the 12 digits that are in the phone numbers that we are going to collect. Ex. 800-123-4567
It doesn't have require 12 characters if there is another way to get the number to validate looking like the example above. Here is my regular expression that I am struggling with:
var re = /[^d-]$/ It seems to block any letters, but it will accept only 1 number. I would really like it to make sure that the phone number is only entered like this: 800-123-4567.
I have looked for days trying to figure this out and have only gotten close.
Regular Expression To Validate Township
Mar 31, 2009I'm trying to validate data in a textbox for township (usually written as 12N or 23S for Township 12 North or Township 23 South). In Utah the townships range from 01N to 15N, and 01S to 44S. The expression "/[0-9][0-4][ns]/i" will allow 01n (or s) through 94n (or s). If I change it to "/[0-4][0-4][ns]/i" to limit it to 44n (or s), I then am not allowing for 05, 06, 07, 08, and 09. I hope the above is not too confusing. I'm just starting to work with regular expressions.
