Validating Email Addresses in Javascript

Question

I think many people have already done some similar development tasks:

I would like to check people's email address only if it matches @ tomtom.com or @ stream.com.

I currently have two solutions:

• Function use indexof()

  var checkTomTomEmail=eo.data.username.indexOf("@tomtom.com");
  var checkStreamEmail=eo.data.username.indexOf("@stream.com");
  
  
  if (checkTomTomEmail >0 || checkStreamEmail >0 )
  {
      //Run the login code
  }
  
  
  Else 
  {
      //Please login with your tomtom or stream email 
  }
  

• Using Compliance

  var patt1=/@tomtom.com/gi;
  var patt2=/@stream.com/gi;
  var checkTomTomEmail=eo.data.username.match(patt1);
  var checkStreamEmail=eo.data.username.match(patt2);
  
  
  if(indexOf(checkTomTomEmail)> 1 ||indexOf (checkStreamEmail)>1)
  {
      //Login 
  }
  

I still think that I am not considering all the details yet. Any suggestions?
thank

Answer 1

Perhaps if people are allowed to enter emails for these two addresses, you should only get a username and then let them choose @ tomtom.com or @ stream.com using radio books.

javascript-,

var emailPatt=/@(tomtom|stream).com/gi;

if(emailPatt.test(eo.data.username))
{
    //Login 
}

Answer 2

...

var emailRegex = /^([0-9a-z])+@(tomtom|stream)\.com$/ig;
if (emailRegex.test(emailRegex)) {
    // Login
}

.match(...) - , .test(...), , - .

:

• " " (, [e-mail])
• (/ - -/i )
• . , "[e-mail]" , "[e-mail]".)

, , 3 , ..

, . :

• "[e-mail] Hello", .
• , # 2 "." Regex, , , , "@tomtom1com", ...
