Regular Expression To Validate Township

Mar 31, 2009

I'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.

Regular Expression Validate Email Address

Jul 23, 2005

/^[a-zA-Z0-9_-]+([.][a-zA-Z0-9_-]+)*@[a-zA-Z_-]+([.][a-zA-Z0-9_-]+)*$/

I'm using this to try to validate a small subset of the valid e-mail
addresses allowed by the relevant RFC (alphanumerics, underscores, and
dashes). I've tested it and it seems to work....

Regular Expression As String Argument?

Feb 24, 2006

I'm finishing my javascript form validator (only text fields for now) and here's one of the last things that's left.

I'm using class names of input elements as parameters for my validator. To find them i use Element.hasClassName(id, class) method from prototype library. I want to implement minlength parameter - so i grab a regexp tutorial and after a minute i had something like this minlength[[1-9][0-9]*], which finds minlength[1], minlength[666] and so on.

Great, but how to pass this as a paramter to hasClassName method, which requires string as a className?

Global String Replacement (was Regular Expression)

Oct 12, 2011

I have just spent a while searching how to use regular expression to strip out spaces in a string and replace them with ',' I don't seem to be getting anywhere and was hoping someone could explain how to do it.

So for example:

Mystring = "a b c d"

My string would end up looking like the following

Mystring = "A','b','c','d"

Regular Expression :: Validate Date-time Field In European D/m/y H:m:s Format

Jul 23, 2005

I have the following regular expression to validate a date-time field
in European or d/m/y h:m:s format.

^((((31/(0?[13578]|1[02]))|((29|30)/(0?[1,3-9]|1[0-2])))/(1[6-9]|[2-9]d)?d{2})|(29/0?2/(((1[6-9]|[2-9]d)?(0[48]|[2468][048]|[13579][26])|((16|[2468][048]|[3579][26])00))))|(0?[1-9]|1d|2[0-8])/((0?[1-9])|(1[0-2]))/((1[6-9]|[2-9]d)?d{2}))
(20|21|22|23|[0-1]?d):[0-5]?d:[0-5]?d$

I wish to ammend it so that the time or h:m:s part is validated only if
supplied (i.e. I wish to make the time part optional). At present if a
time is not supplied the validation fails. I gather that the following
part of the above expression

(20|21|22|23|[0-1]?d):[0-5]?d:[0-5]?d$

validates the time, however I don't know the syntax to make it
optional.

Match Entire String (regular Expression & Javascript)

Jul 23, 2005

I'm trying to perform a very simple validation of user input. I
want to verify that the user entered a six-digit string consisting
entirely of numbers. So anything from 000000 to 999999 is considered
valid. The problem that I'm having is getting the validation to work on
the entire string. In other words, 000000 is okay but 000000000000 is
also returning as a match. Here's a quick code block...I have something
along these lines....

/*********************/
<html>
<body>
<INPUT name="txtNumberField" type="text" id="txtNumberField">
<INPUT onClick="fnTestNumberField()" id=Button1 type=button value="Test
Number!" name=btnTest>
<script language=javascript>
function fnTestNumberField()
{
var sNumberValue = document.getElementById("txtNumberField").value;

if (sNumberValue.match(/A[0-9]{6}z/))
{
alert("match");
} else {
alert("no match");
}
}
</script>
</body>
</html>
/******************/

That is failing when I enter 123456 into the textbox. Why, though? I
know I can replace...

if (sNumberValue.match(/A[0-9]{6}z/))

....with something like...

if (sNumberValue.length == 6 && sNumberValue.match(/[0-9]{6}/))

....or I could assign a maxlength to the input box, of course. The thing
is, I really want to know WHY the regular expression isn't responding
as I'd expect. Is there a syntax error somewhere in the code?

Regular Expression That Tests A String To Find Out If Not Empty

Jun 25, 2010

Just a quick one here I want a regular expression that tests a string to find out if not empty. I am currently using /^[a-zA-Z0-9]+$/ which allows all alphanumeric characters, however unfortunately does not allow white space. As I am trying to use the RE for a form name input and I don't wish to separate first and last name, I want to allow users to enter their full name including spaces. Can anyone tell me an RE that allows all alphanumeric characters and white space in a string but does not allow an empty string

Regular Expression - Enter A String That Is 2 - 20 Characters Long And Only Has Letters Doesn't Work

Jun 28, 2010

I wanted to try creating a basic expression first. I want someone to enter a string that is 2 - 20 characters long and only has letters. This is what I use so far, and it doesn't work, nothing happens at all when I run it.

Code:
// Check for a valid name.
var namePattern = new RegExp("/^[a-zA-Z]{2,20}$/");
if (namePattern.test(name))
{
window.alert("Invalid");
}

name comes from a input box I display on screen. Also, I would like to update the expression so that there can be one space in the string, but it cannot be at the beginning or end. So this string is like a persons name. Bob is OK, Bob Smith is also OK. Edit: Actually, it is doing something but its always coming back invalid.
