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"

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.

?: In Regular Expression

Feb 21, 2006

I 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???

Regular Expression To Get The File Name From A URL?

Feb 5, 2009

regular 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.
