Email address field cannot allowed the capital letters, special characters except '@' symbol.
But can allowed the small letters, numeric numbers.
Now i use this script for validate the email address. But it allows the cpital letters otherwise its working correctly.
SCRIPT FUNCTION
************************************************
Expand|Select|Wrap|Line Numbers
- function validateEmail(addr,man,db) {
- if (addr == '' && man) {
- if (db) alert('Email address is mandatory');
- return false;
- }
- var invalidChars = '\/\'\\ ";:?!()[]\{\}^|';
- for (i=0; i<invalidChars.length; i++) {
- if (addr.indexOf(invalidChars.charAt(i),0) > -1) {
- if (db) alert('Email address contains invalid characters');
- return false;
- }
- }
- for (i=0; i<addr.length; i++) {
- if (addr.charCodeAt(i)>127) {
- if (db) alert("Email address contains non ascii characters.");
- return false;
- }
- }
- var atPos = addr.indexOf('@',0);
- if (atPos == -1) {
- if (db) alert('Email address must contain an @');
- return false;
- }
- if (atPos == 0) {
- if (db) alert('Email address must not start with @');
- return false;
- }
- if (addr.indexOf('@', atPos + 1) > - 1) {
- if (db) alert('Email address must contain only one @');
- return false;
- }
- if (addr.indexOf('.', atPos) == -1) {
- if (db) alert('Email address must contain a period in the domain name');
- return false;
- }
- if (addr.indexOf('@.',0) != -1) {
- if (db) alert('period must not immediately follow @ in email address');
- return false;
- }
- if (addr.indexOf('.@',0) != -1){
- if (db) alert('period must not immediately precede @ in email address');
- return false;
- }
- if (addr.indexOf('..',0) != -1) {
- if (db) alert('two periods must not be adjacent in email address');
- return false;
- }
- var suffix = addr.substring(addr.lastIndexOf('.')+1);
- if (suffix.length != 2 && suffix != 'com' && suffix != 'net' && suffix != 'org' && suffix != 'edu' && suffix != 'int' && suffix != 'mil' && suffix != 'gov' & suffix != 'arpa' && suffix != 'biz' && suffix != 'aero' && suffix != 'name' && suffix != 'coop' && suffix != 'info' && suffix != 'pro' && suffix != 'museum') {
- if (db) alert('invalid primary domain in email address');
- return false;
- }
- return true;
- }
I need script for not allowed the capital letters.
Please any one can help me to rectify the email validation problem.
