This script will make your form look good and attractive ,you can go through this script and can play around this by changing the attribute the change in attribute value you will see changes in the designing part of form ,and you can make it of your choice. family=Raleway); #main span h2 hr #login input[type=text],input[type=password] input[type=submit] #profile i #right #right p #paypal_logo #results table thead tr th td tbody tr #return #return h3#success #return P #return .back_btn #btn a .success_main_heading #return h3#fail ul li hr.style-four hr.style-four:after #dsubmit #txtmsg Hope you would have enjoyed this post, I am sure you will give a try to the script provided and implement it in your own projects as well.
I think it’s a bit of an overkill for most use cases.
Taken from Paul Warren’s page on the RFC822 Perl module: I generally avoid this sort of coding, but it will work in a pinch.
This index page have both html code and java script code , when you will execute this page you will get a form on screen asking for entering the email id and message and then submit form by pressing submit button.
and java script code will validate the user for the cases like “unfilled form field” or”filled incorrect text” , in this script email address field is validating by regular expression(regex) which is quite strong validation type.
Restrictions in above regex are:1) A-Z characters allowed 2) a-z characters allowed 3) 0-9 numbers allowed 4) Additionally email may contain only dot(.), dash(-) and underscore(_) 5) Rest all characters are not allowed Let’s test some email addresses against above regex.
List emails = new Array List(); emails.add("[email protected]"); emails.add("[email protected]"); emails.add("[email protected]"); emails.add("[email protected]"); emails.add("[email protected]"); emails.add("[email protected]"); emails.add("[email protected]"); //Invalid emails emails.add("@yahoo.com"); String regex = "^[A-Za-z0-9 _.-] @(.
This may look like a disturbing feature, but I have added a simple check at beginning to skip this checkup if the field is blank.
The regular expression used here is To implement this on a textbox, add the onblur attribute to the textbox with value as return blur Email Check(this);. NET 2.0 allows direct addition of html attributes into an ASP.
You should be sure to escape sensitive characters when inserting the email address into a string passed to another program, in order to prevent security holes such as SQL injection attacks. :\.[a-z A-Z0-9-] )*$"; Pattern pattern = Pattern.compile(regex); for(String email : emails) Output: [email protected]: true [email protected] : true [email protected]: true user'[email protected] : true [email protected]: false [email protected] Please feel free to use this regex as well as edit it as per your application’s additional needs.
List emails = new Array List(); emails.add("[email protected]"); emails.add("[email protected]"); emails.add("[email protected]"); emails.add("user? : false [email protected]: false Now lets modify the regex such that domain name must include at least one dot, and that the part of the domain name after the last dot can only consist of letters. The top-level domain (in these examples) must consist of two to six letters only.
There may be more usecase but that’s not point of discussion here. validating email address in java using regular expressions.
