Regular Expression :: Validate Numbers Separated By Period (.)
Dec 19, 2005
I need a regular expression to validate a string which consists of numbers, seprated by a period. For example: 123.456.7890.123 or
543245634.564362454.543543523.43532543
Basically, its a set of any amount of numbers, seperated by a period, ocurring any number of times. Now this is my first time dealving into regular expressions, and after reading some tutorials i came up with this:
what is the regular expression for a comma-separated list (in this case - IPs) ?My list looks like this: 192.168.0.1, 10.%.23.100, %.46.%.1So far I managed to create this:^[0-9%]{1,3}.[0-9%]{1,3}.[0-9%]{1,3}.[0-9%]{1,3}$But I don't know how to specify a comma-separated list of the above sequence.
Here is the form in question: spraytechDOTcom/download_form.asp I am so close to getting this to work the way that I want, but here is what I am having an issue with: I cannot seem to make it look for the 12 digits that are in the phone numbers that we are going to collect. Ex. 800-123-4567
It doesn't have require 12 characters if there is another way to get the number to validate looking like the example above. Here is my regular expression that I am struggling with:
var re = /[^d-]$/ It seems to block any letters, but it will accept only 1 number. I would really like it to make sure that the phone number is only entered like this: 800-123-4567.
I have looked for days trying to figure this out and have only gotten close.
I'm developing a web app and I want to validate a users input on a form. I need a regular expression to validate a string which must begin with a letter (i.e. A-Z or a-z) and must have 5 numbers (0-9) after it....
I'm looking to use Javascript to pull apart a page of HTML I have already fetched. The page contains a table, within which there are rows containing...
Either:
0000000 - 0000000<some html>00<some html>0
or:
0000000 - 0000000<some html>00 - 00<some html>0
I'm interested in extracting only the numbers (which may not always be 0!), in each case. I bet this can be done using a regular expression (or two). Can anyone help?
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.
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....
Does anyone know if it is possible to use your own regular expression for fields with the JQuery Validation plugin?I have previously used Live Validation (standalone) which allows you to do this kind of thing:var loginpass = new LiveValidation('loginpass');loginpass.add( Validate.Format, { pattern: /^[A-Za-zd]+$/i } );
Does anyone know of a regualr expression to validate US and Canadian Postal Codes? I want to be able to accept ##### or #####-#### or Canadian A#A #A# that is alpha,number,alpha number,alpha,number.
I am new to regular expressions. The US 5 digit part is easy, but I get stuck after that.
I wish to ammend it so that the time or h:m:s part is validated only if supplied (i.e. I wish to make the time part optional). At present if a time is not supplied the validation fails. I gather that the following part of the above expression
(20|21|22|23|[0-1]?d):[0-5]?d:[0-5]?d$
validates the time, however I don't know the syntax to make it optional.
i am using the following regular expression for the validation of Email address /^.+@([?)[a-zA-Z0-9-.]+.([a-zA-Z]{2,3}|[0-9]{1,3})(]?)$/; but the problem is that if user enters any white space character while entering email address then email is considered as valid how ever we know that an email address can not contain any white space character i have tried a lot but could not get a correct regular expression
validation ' <strong>Email Validation for multiple emails (comma separated)</strong> ' for textarea. I am writing Regular expression but not able validating the given input with comma
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.

how can i get "src" value in above code using regular expression?
does anyone know how I can build a regular expression e.g. for the string.search() function on runtime, depending on the content of variables? Should be something like this:
var strkey = "something"; var str = "Somethin like this";
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.
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.
