Using Regular Expressions is probably the best way. Here's an example (live demo):

function validateEmail(email) { 
    var re = /^(([^<>()[\]\\.,;:\s@\"]+(\.[^<>()[\]\\.,;:\s@\"]+)*)|(\
".+\"))@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\])|(([a-zA
-Z\-0-9]+\.)+[a-zA-Z]{2,}))$/;
    return re.test(email);
}

But keep in mind that one should not rely only upon JavaScript validation. JavaScript can easily be disabled. This should be validated on the server side as well.

Update: Then use the JavaScript split() function to split the mail address after the '@' and check the value versus your strings.

var mail = yourMailAdress.split("@");
if (mail[1] == "gmail.com" || mail[1] == "yahoomail.com") {
    // OKAY
} else {
    // false
}
