多选题评分算法 求指导

Question

多选题评分规则
每个正确选项都有得分权重，选正确一个给该正确选项得分权重的分值，选错一个，则总分为0
假如:正确答案ABC，总分10分，权重分别为20%40%40%
提交答案ABC得（20%+40%+40%）*10=10分
提交答案AB得（20%+40%）*10=6分
提交答案ABD得0分
集思广益，如果可以请使用PHP作答

Answer 1

functionselectScore(preAnswerScore,answer){lettotalScore=0;letnoScoreKey=[];lethasNoScoreKey=false;for(letkeyinpreAnswerScore){if(preAnswerScore[key]==0){noScoreKey.push(key);}}noScoreKey.map(item=>{if(answer.includes(item)){hasNoScoreKey=true;}});if(hasNoScoreKey){totalScore=0;}else{answer.map(item=>{totalScore+=preAnswerScore[item];});totalScore/=10;}returntotalScore;}letpreAnswerScore={a:20,b:40,c:40,d:0};letanswer=['c','b','d']console.log(selectScore(preAnswerScore,answer));}js走一波，考虑到你其他选择题也适用

Answer 2

不会php，用一下js//选择的选项constselect=['a','b','d']//分数constscore={'a':20,'b':20,'c':60,'d':0}//根据所选得到分数如：abd的到20,20,0consta=select.map(x=>score[x])//如果a里面有0直接返回0否则reduce后得到分数total=a.includes(0)?0:a.reduce((total,i)=>total+(i*0.1),0)
