Question

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

I would like to check the people’s email address whether only match @tomtom.com or @stream.com.

Currently, I have two solutions in my mind:

1. Using indexof() function

   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 
   }
   

2. Using match

   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 I do not consider all the detail yet. Any suggestions?
Thanks

Answer 1

Perhaps if people are only allowed to enter emails for those two addresses you should only collect the username and then allow them to choose @tomtom.com or @stream.com using radiobuttons.

If you still want to go the javascript route then your regex can be combined into a single statement

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

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