Question

tenho essa funcao javascript que valida email:

if (document.getElementById('email').value.search(/^\w+([\.-]?\w+)*@\w+([\.-]?\w+)*(\.\w{2,3})+$/) == -1)
{
    alert("E-mail Inválido.");
    document.getElementById("email").focus();
    return false;
}[/code]

ela funciona certinho sem problema nenhum.

mas to postando aqui porque queria que alguém me explicasse como ela funciona porque eu não entendo nd.

o que são aquele monte de rabiscos passados de parametro no search?? o que eles fazem?? alguém saberia explicar??
