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.
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}$/ (taken from the jquery validationengine) to check if the email address is correctly formated but I'd like to reject it if contains hotmail between the @ and the. I tried many things but couldn't get something that works.
I'm finally diving into regexp by porting a perl script over to js that uses regexp to compress javascript into a bookmarklet capable format.I've successfully worked out 90% of the expressions but am troubled with a few, this one at the moment is odd:I want to remove the first line if it hasjavascript:So I thought str.replace(/^javascripts+:s+/, "") would be ok. I want javascript text, any space, colon, any space and new line. what I'm doing wrong.btw this is the original perl version
I found this in felgall's page. I added script tag
<script type="text/javascript">
var re = /(t)he/g; var mystring = "Over the moon."; re.text(mystring); alert(RegExp.input); // or RegExp.$_ 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 field names in HTML with a period in them for e.g. <INPUT TYPE='hidden' NAME='cars.toyota.camry' VALUE=དྷK'> I need to know how to access this field name in Javascript.
I want to rotate content every x seconds but my app often sits in another tab out of view for a period of time.Basically after a period of time, if the div is viewable by the user, I would like to refresh it. How can I do this?The time part is easily. How do I also detect the div is in view?
I want to run a quiz competion on my website in which after logging any user play that quiz, like I will give 50 question to solve in just 3 min time, all will be objective question, now after that 3 min, quiz will automatically end and all users marked answer entered to the database, means he has not press any submit button, but after specific time all answer automatically enter in the database, and he come out from it..
Now I am using this timer: <!DOCTYPE HTML PUBLIC "-W3CDTD HTML 4.01 TransitionalEN" "[URL]"> <html><head> <title>Untitled Document</title> <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1"> </head><body> <?php $dateFormat = "d F Y -- g:i a"; $targetDate = time() + (1*60);Change the 25 to however many minutes you want to countdown $actualDate = time(); ..... Where to bring changes or which new thing is to be added.
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:
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:
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.
To give you a little background about myself, I am a complete JavaScript novice. I am used to SQL scripting a little. We have recently moved to a web IT Service tool, we have taken on the programming of this tool and it is mostly using JavaScript. Within my tool I am trying to create a field to display the financial Period Number, based on the open date of a task using a 4 weekly rotation. Therefore what I am trying to code is;
I'm a mediocre website designer i know html , at JS i'm to noob to actualy make something of my own :) just Edit, i'm still learning and atm i'm working on a web project and I'm struggling to find a way to Filter email addresses to redirect my New Members to their e-mail provider, for example if they would register newmmember@hotmail.com to be forwarded to www.hotmail.com so they would login and activate their account, or if they enter @yahoo.com to be forwarded there . Can you please point out a few things i'm eager to learn how to Forward User to email provider after he creates his account . Or how can i forward email to URL inside my webpage , this could help me with another ideea i have, again this would have to be filtered @yahoo.com , @hotmail.com etc , to be forwarded to a local URL inside the site depending on what Email Provider they enter .
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.

Is it possible to create a page (with javascipt) that will send an email to the "me" but the user can't see the destination email address? Im wondering if I can do the "party" with Javascript without using some server page like PHP.
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. On refresh, the image is back. I know that i have to use jquery cookies, but i'm really new to jquery so I've got no clue how to set up the cookies into that script.
