JS - Email Regexp With ONLY One Period Possible Before @
Feb 21, 2010
I am attempting to do a basic email format validation in JavaScript on a very basic form with fields for name, address, email, etc.
Requirements: A period can occur before the @, but not twice in a row -- as in jane.doe@xyz.com but not jane..doe@xyz.com. Email must start with a letter. I'm also allowing underscores and hyphens before the @, but I'm not worrying about whether there's only one of each -- I'm just allowing those. Must end in .com, .net, .org. Nothing else.
[Code]...
I have read extensively on this site and several others and haven't found a solution to the "one and only one period allowed in succession, but not required" problem. I haven't found a successful way to limit periods to only 1 in a row yet still have the rest of the validation work properly. I get the symbols in general, but as a newbie can't seem to make them do this one thing that I want them to do.

My understanding of regular expressions is rudimentary, at best.
I have this RegExp to to a very simple validation of an email-address, but it turns out that it refuses to accept mail-addresses with hypens in them.
Can anybody please help me adjust it so it will accept addresses like dag-sunde@test-domain.net too?
Here's what got:
function validateEmail(eMail) {
return /^(w+.)*(w+)@(w+.)+([a-zA-Z]{2,4})$/.test(eMail);
}

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 finally diving into regexp by porting a perl script over to js that uses regexp to compress javascript into a bookmarklet capable format.I've successfully worked out 90% of the expressions but am troubled with a few, this one at the moment is odd:I want to remove the first line if it hasjavascript:So I thought str.replace(/^javascripts+:s+/, "") would be ok. I want javascript text, any space, colon, any space and new line. what I'm doing wrong.btw this is the original perl version
$src =~ s{^// ?javascript.+:.+
}{};

I found this in felgall's page. I added script tag
<script type="text/javascript">
var re = /(t)he/g;
var mystring = "Over the moon.";
re.text(mystring);
alert(RegExp.input); // or RegExp.$_
alert(RegExp.leftContext); // or RegExp["$`"]
alert(RegExp.rightContext); // or RegExp["$'"]
alert(RegExp.lastMatch); // or RegExp["$&"]
alert(RegExp.lastParen); // or RegExp["$+"]
alert(re.source);
</script>
I don't see message box. Please tell me what I can do.

I'm using jQuery to add some extra functionality to our Request Tracker installation, and I've run into a small problem. It uses generated ids for various elements, including one I want to use in a selector. The id is 'TitleBox--_Ticket_Display.html--ticket-info-requestor-------0', which as far as I can tell is valid, but has a period in the middle of it. If I use either of:
Then I don't get a hit. I also tried using \2E for the period, with no luck. Is there another method to select these nodes?

I am having difficulties with my code and i've tried many ways to do everything from do while to if else statements. i've got everything in my code down but that pesky loop statement, and i'm trying to write my code where it says if one of either of variable Orbital Period or Semi-Major Axis is a zero, then it should use different way to read the inputed information.

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:
/+((+d).)/
Would this evaluate correctly?

Heres my javascript code that will verify email from email input field and check if the checkbox (I agree condition) was checked:
[Code]....
However, this will work fine when calling with a link "javascript:validate('inputForm');" but if I try to prevent users by submitting form with pressing enter I put it in form onSubmit parameter: <form .. onSubmit="javascript:validate('inputForm');"> which will check the forms and submit data (do return) no matter if it matched or no.

Last week after much searching, I found the answer to my problem in
this newsgroup. I can't find the thread from which I got my solution,
but I wanted to report back what worked.
When the site visitor fills out the form and submits it, this calls a
rather ordinary asp script like formmail.asp that sends the emails and
displays a "thank you" web page. At the very end of my "thank you" web
page I placed the following:
<script type="text/javascript">
location.href="FileToDownload.exe"
</script>
This causes the file download to get triggered, and asks the user if
they want to save the file. In limited testing this appears to work
fine in both Firefox and IE.

I have a frameset and one of the frames contains a page that is created on the fly, an
actual word document. I want to have a button in one of the other frames that emails this created page as an email attachment using the email client (outlook or whatever). I created a function as follows:
<script language="JavaScript">
function mailIt()
var page = parent.QandA;
document.write 'mailto: sendmail@example.com?subject=The
document&Attachment='
document.write page;
}
</script>
Which is then called from a button, but it doesnt work! QandA is the
name of the frame that contains the document I want to email as the
attachment.

I'm displaying ads on my website, but I would like to hide the script for, let's say 12 hours, after it has been clicked on it. I somehow managed to create something, but it's still not what I want.

Im using a jQuery script to show/hide a div based based on the selection made via a dropdown.
<script type="text/javascript" src="jquery-1.3.2.min.js"></script>
The problem im having is that the value used in the dropdown lists are price values eg 10.00
Consequently jQuery seems to interprit these as css notations, meaning the code doesnt work.
