[ms.buggy]

Hello,

I'm trying to check if the variable starts with certain digits, possible begins are +367 and +352.

I tried to set if  set something like this:

if ((gsm.charAt(0)!="+" && gsm.charAt(1)!=3 && gsm.charAt(2)!=6 && gsm.charAt(3)!=7) || (gsm.charAt(0)!="+" && gsm.charAt(1)!=3 && gsm.charAt(2)!=5 && gsm.charAt(3)!=2)){

 

Can someone help me with this issue?

You should use a regular expression to get a match. Also why are you using charAt? That's not PHP that's javascript
