combine a javascript if together

this is what i have now

if (selectVal.value == 'Rental House') {
document.getElementById('rental_table').style.disp lay='';
document.getElementById('main_table').style.displa y='none';
}
else if (selectVal.value == 'Rental Unit') {
document.getElementById('rental_table').style.disp lay='';
document.getElementById('main_table').style.displa y='none';
}

is there a way i can combine it like this.

if (selectVal.value == 'Rental House',***or***'Rental Unit') {
document.getElementById('rental_table').style.disp lay='';
document.getElementById('main_table').style.displa y='none';
}

just that i have more like this for example i need to create one
that will have 5 if else and it gets very confusing..


cheers aron.

simply put || inbetween the statements

if (selectVal.value == 'Rental House' || 'Rental Unit') {

|| is or

&& is and

If you wanted to do something different, depending on the value, you would be better to use a "switch" statement (commonly called a "case" statement)... otherwise, if the action to be taken is the same for all, then use the above suggestion.

same as php cool thanks.

aron.

REALLY??

the || operator works like that?

I would have done

if( selectVal.value == 'Rental House' || selectVal.value == 'Rental Unit') {

oops my mistake =[
