多選題評分規(guī)則每個正確選項都有得分權(quán)重，選正確一個給該正確選項得分權(quán)重的分值，選錯一個，則總分為0假如:正確答案ABC，總分10分，權(quán)重分別為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分集思廣益，如果可以請使用PHP作答

不會php，用一下js//選擇的選項constselect=['a','b','d']//分?jǐn)?shù)constscore={'a':20,'b':20,'c':60,'d':0}//根據(jù)所選得到分?jǐn)?shù)如：abd的到20,20,0consta=select.map(x=>score[x])//如果a里面有0直接返回0否則reduce后得到分?jǐn)?shù)total=a.includes(0)?0:a.reduce((total,i)=>total+(i*0.1),0)
