Hola, como puedo mandar una funcion javascript a un archivo PHP para luego enviarlo por correo les dejo algo de codigo...

Mi funcion JS
function visualizarcarrito() {
numerodeorden = 0;
subtotal=0;
preciototal=0;
numerodeorden = getcookie("numerodeorden");
tablas = "";
for (i = 1; i <= numerodeorden; i++) {
nuevopedido = "Order." + i;
datos = "";
datos = getcookie(nuevopedido);
ficha0 = datos.indexOf("|", 0);
ficha1 = datos.indexOf("|", ficha0+1);
ficha2 = datos.indexOf("|", ficha1+1);
campos = new Array;
campos[0] = datos.substring( 0, ficha0 );
campos[1] = datos.substring( ficha0+1, ficha1 );
campos[2] = datos.substring( ficha1+1, ficha2 );
campos[3] = datos.substring( ficha2+1, datos.length );
subtotal = subtotal + (campos[1] * campos[0]);
preciototal = formatoeuros(subtotal);
tablas += "<tr style='font: 9pt; text-align: justify; color=white'><td>" + campos[2] + "</td><td style='color=navy'>"
+ campos[3] + "</td>"
+ "<td><input type=button id=boton value=\" Eliminar \" onClick=\"quitardelcarrito("+i+")\">"
