Is there any reason why RegExp wouldn't be able to find a period?
str = '256.89';
a = new RegExp('(\.)');
b = /(\.)/;
alert(str.repla ce(a, 'x$1x'));
alert(str.repla ce(b, 'x$1x'));
The alert for a says
x2x56.89
However the alert for b says
256x.x89
b is the result I want, because it means that the period was found. a
is just finding a single character, as if it's ignoring the escape in
front of the period.
I've tried this in IE and Mozilla.

Here's a hint:
When used in a STRING, the backslash is the escape character.
b = /(\.)/;
alert(str.repl ace(a, 'x$1x'));
alert(str.repl ace(b, 'x$1x'));
The alert for a says
x2x56.89

Yeah, what you actually need to do is:
a = new RegExp('(\\.)') ;
when its a string.

Sometimes the solution is so simple. Thank you very much.
What's strange is at one point I had written it \\. and things weren't
working the way I expected. But that was when I was trying it as part
of a larger regular expression. Another piece of the expression must
have been wrong. Things are working now. This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics | |

Hi everyone!
How can I simply search text for regexps (lets say <a

Or how can I replace the html &entities; in a string
"blablabla&blablabal&balbalbal" with the chars they mean using
re.sub? I found out they are stored in an dict . I though about this functionality:

• Sorting and Searching
• Numerical Analysis
Design Specification
You are to write a program called “StockAnalyser”. Your program will read a text file that
contains historical price of a stock. The program will allow users to query the stock price of a
particular date and output its statistics (mean price, median price and standard deviation) for any
specified period. Your program must be menu driven and works as follows.

Hello all,
I have just discovered (the long way) that using a RegExp object with
the 'global' flag set produces inconsistent results when its test()
method is executed. I realize that 'global' is not an appropriate
modifier for the test() function - test() searches the entire string
by default.
However, I would expect it to degrade gracefully. Instead, I seem to
be getting something as follows - using W3Schools handy page at :

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
