대분류 - 중분류 - 소분류  이렇게 3개의 셀렉트 박스가 있는데요.

각각의 셀렉트박스는 쿼리를날려서 선택할수 있게끔 하였습니다.

문제는 대분류를 선택하면 확인버튼을 안눌러도 쿼리를 날려 그조건에

맞는 결과가 출력이 돼버립니다. ( 이거 때문에 느려집니다.)

3개의 셀렉트 박스를 조건 선택후 확인버튼을 눌러야 결과가 출력되게 하려면

어떻게 하나요?


소스는 다음가 같습니다.

function cate1Select() {
document.searchForm.cate2.options[0].selected = true;
document.searchForm.cate3.options[0].selected = true;
document.searchForm.submit();
}
function cate2Select() {
document.searchForm.cate3.options[0].selected = true;
document.searchForm.submit();
}
function cate3Select() {
document.searchForm.submit();
}
