Regular Expression - Validate That An Email Address Cannot Contain Any White Space Character?
May 22, 2009
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
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....
I need to check that the user as put in at least one character between a-z upper or lowercase in a name field. They can put in whatever they like but there as to be a character a-z in the string. How shall the test expression look like?
I am stuck on this seemingly simple validation loop.I want to iterate through a list of comma separated emails entered in a textarea input and check their validity before submitting the form.For some reason even when I enter all valid emails every other email doesn't pass the validation test!
var okEmailArr = badEmailArr = new Array(); var emails = $('#emailList').val(); // Get email list from text are input[code]....
I'm trying to validate data in a textbox for township (usually written as 12N or 23S for Township 12 North or Township 23 South). In Utah the townships range from 01N to 15N, and 01S to 44S. The expression "/[0-9][0-4][ns]/i" will allow 01n (or s) through 94n (or s). If I change it to "/[0-4][0-4][ns]/i" to limit it to 44n (or s), I then am not allowing for 05, 06, 07, 08, and 09. I hope the above is not too confusing. I'm just starting to work with regular expressions.
Does anyone know if it is possible to use your own regular expression for fields with the JQuery Validation plugin?I have previously used Live Validation (standalone) which allows you to do this kind of thing:var loginpass = new LiveValidation('loginpass');loginpass.add( Validate.Format, { pattern: /^[A-Za-zd]+$/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 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:
Trying to make a 2 page application. First is an introduction page and second is the content. Ive put a pop up box in the head of the second page and it asks for email, but how do i make it so if the email is incorrect it will not go onto the second page? at present if i click the link for the second page the box pops up but that is it. I can document.write their response and it comes on the top of the second page, but i want it validated!
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 want to check the email address type in a contact form but want to reject it if it's from a certain domain I actually use this regexp : /^[a-zA-Z0-9_.-]+@([a-zA-Z0-9-]+.)+[a-zA-Z0-9]{2,4}$/ (taken from the jquery validationengine) to check if the email address is correctly formated but I'd like to reject it if contains hotmail between the @ and the. I tried many things but couldn't get something that works.
I'm doing a registration form.I want to validate the email address before submitting the form using ajax.That is to verify if the email address already exist in the database.
I've built a simple script to validate the email address and password on a form, the email part of it is working, but the password isn't, any idea what I've done wrong here? Code:
I am creating a class for all of my code snippets, using a formatted paragraph (and "word-wrap: pre") to keep formayting intact. The problem is that in keeping my HTML files formatted nicely, they are indented, and due to the "pre" formatting the indentation is kept. Code:
Right now when someone clicks on my listbox I immediately do an update on the form to populate the selected item.
Is there a way to detect if a user has clicked on some white area of a list box? If my list is sized 8 items but the list only has 4 items, if the user clicks near the bottom of the list where there is no item to select, can I detect that? Currently I get the form updating even if I click on the white area of the list and I'd like the form to update only if I actually click on an item in the list.
I have a frame that includes a hidden <div> at first (before any action), the problem is that when opening the page, I have a white space, and i can't reduce the size of the frame because the content of the <div> will not appear!
how to hide the white space of the frame without reducing it's size?
