Regular Expression To Match Any Spaces

Oct 9, 2007

Normally 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 And Match Anything Between Two Characters

Sep 19, 2009

I 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, 2010

I 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)))$";

[Code].....

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 :: Match Letter But Leave Html Entities Alone

Mar 14, 2007

I 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:

<div>
This is the content &nbsp; &lt; Hello &gt;
</div>

Just as an example to make it more clearer, If I wanted to replace the all letters of the message with the number "1" I would have this result:

<div>
1111 11 111 1111111 &nbsp; &lt; 11111 &gt;
</div>

Test Strings Against A Regular Expression - Getting "No Match"

Jul 6, 2009

I am trying to test some strings against a regular expression, but have tried at least 10 different online testers with no success at all. Plus I've tried some code to do it myself, again with no success. I know for a fact that some of the strings should match and some shouldn't match, but I am getting "No match" returns from all the strings.

Does somebody have some page code that has the regular expression in some javascript code in the head section of a document, then a form in the body that I can enter the text string, click a button, and I get an alert saying if the string matches or not?

Regular Expression - Match ",.[]" - Cannot Put Them Into The Square Brackets

May 3, 2010

for the character classes [ ], if i want to match ,.[] i cannot put them into the square brackets so how to deal with that? what if the characters are . or ! or ." (<-- combined) it fails if the regexp is [.!(.")] which will treat ( as one of the element. also the book javascript: the definitive guide says that (?=p) requires that the following characters match the pattern p, but do not include those characters in the match. However, the browser failed to figure this out (IE8) i.e. "asd:ert".match(/(?=:)w/) returns null

Regular Espressions And .match()

Jan 21, 2003

I have a regular expression called mCheck and a variable called usrVal which contains &#391;/20/41/11/22' I then use the usrVal.match(mCheck) so the code looks like the following

var mCheck = /^[0-9][0-9]/;
if(!usrVal.match(mCheck))
{
usrVal = &#390;' + usrVal;
}

Now, I was under the impression that if there wasn't a match then the match method would return boolean 'False'. However it is returning 'null' instead... I have used this exact same check on other pages before and it returned false just fine....

?: 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.

Comma Delimited Regular Expression

Dec 7, 2006

I 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 Exclude Lines?

Jul 20, 2005

All 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.
