Match Entire String (regular Expression & Javascript)
Jul 23, 2005I'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?
Extract Digits With Regular Expression?
Jun 4, 2011I have the following string "d3-23-76-546"
I'm looking for a regular expression that will match everything in this string before 546 so that I can replace it with an empty string and just be left with 546. The string could be of any length and contain any number of hyphens.

Regular Expression :: Allow 1,2 Or 3 Digits Before Decimal Point
Jun 8, 2006I wrote a regex to edit a decimal number. you're allowed 1,2, or 3
digits before the decimal point, and 0,1,2,or 3digits after the decimal
point. Of course, you can't enter a decimal point without at least a
digit after ("5." is invalid). So here is my regex
pattern=/^d{1,3}(.(?=d))d{0,3}$/
This works fine for every case except an integer. In other words, it
tests false for entering 5, or 567.
I don't see why it tests false for integers. I'm allowing 1-3 digits
before the decimal point, then a decimal point only if the next
character is a digit (the lookahead clause), and then 0-3 digits after
the decimal point.
I've gotten around this problem with other javascript code around
the regex, but I'd just like to know why this "clean" solution doesn't
work.

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

abc123 is fine, abc 123 is not. Any character is fine, just not a
space.

Regular Expression And Match Anything Between Two Characters
Sep 19, 2009I have the following code:
var str = "/dev/filler/test0/";
var patt = new RegExp("/test0/$");
var result = patt.exec(str);
document.write(result);
which returns: /test0/
in the var patt line I would like to replace the hardcoded test0 string with an expression that matches any characters between the two forward slashes. I have tried with little success.
Regular Expression Match Always Returns Null
Feb 12, 2010I found this regular expression on the internet and it works fine when I test it in various validators on the web.
Code:
^(((0?[1-9]|1[012])/(0?[1-9]|1d|2[0-8])|(0?[13456789]|1[012])/(29|30)|(0?[13578]|1[02])/31)/(19|[2-9]d)d{2}|0?2/29/((19|[2-9]d)(0[48]|[2468][048]|[13579][26])|(([2468][048]|[3579][26])00)))$
It's purpose is to check for valid date and allows formats mm/dd/yyyy, m/dd/yyyy, mm/d/yyyy or m/d/yyyy.
When I try it with the code below it always returns null.
Code:
function isValidDate(/* String */ p1_date) {
var x = "^(((0?[1-9]|1[012])/(0?[1-9]|1d|2[0-8])|(0?[13456789]|1[012])/(29|30)|(0?[13578]|1[02])/31)/(19|[2-9]d)d{2}|0?2/29/((19|[2-9]d)(0[48]|[2468][048]|[13579][26])|(([2468][048]|[3579][26])00)))$";

Mar 14, 2007I need to figure out a pattern that can match each letter of the message, but leaves all the html entities alone.
For example, I have a input like this:

Regular Expression As String Argument?
Feb 24, 2006I'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?
