script language="JavaScript"

function scoref(f1) {

var score=0;

if(f1.R1.value=="產(chǎn)品觀念") score++;

if(f1.R2.value=="集中策略") score++;

if(f1.a1.value=="廣告") score++;

if(f1.a2.value=="滲透定價(jià)") score++;

if(f1.a3.value=="同心多角化") score++;

if(f1.組合.value=="寬度"+"長度"+"深度"+"關(guān)聯(lián)性") score++;

if(f1.市場.value=="消費(fèi)者市場"+"生產(chǎn)者市場") score++;

alert("你的成績?yōu)?"+score);

}

/script

注意：

如果下邊這段代碼有問題的話也不行

if(f1.R1.value=="產(chǎn)品觀念") score++;

if(f1.R2.value=="集中策略") score++;

if(f1.a1.value=="廣告") score++;

if(f1.a2.value=="滲透定價(jià)") score++;

if(f1.a3.value=="同心多角化") score++;

if(f1.組合.value=="寬度"+"長度"+"深度"+"關(guān)聯(lián)性") score++;

if(f1.市場.value=="消費(fèi)者市場"+"生產(chǎn)者市場") score++;

自己研究吧
