這個(gè)代碼寫(xiě)的好啊（借鑒）

尤其是這句?score[i] = parseInt(mystr[i].split(":")[1]);很喜歡

1、字符串scoreStr被分裂成數(shù)組mystr=["小明:87","小花:81","小紅:97","小天:76","小張:74","小小:94","小西:90","小伍:76","小迪:64","小曼:76"]
2、第一次循環(huán)時(shí)，i=0，
mystr[0]="小明:87"，
mystr[0].split(":")=["小明","87"]是一個(gè)數(shù)組，
mystr[0].split(":")[0] ="小明"，mystr[0].split(":")[1] ="87"
而你說(shuō)的mystr[0].split(":",1)只取第一個(gè)字符串，所以這個(gè)數(shù)組的長(zhǎng)度為1，mystr[0].split(":",1)="小明"
3、所以是我錯(cuò)了~不好意思啊，誤導(dǎo)你了~趕緊改正@劉榮軒1991

2、第一次循環(huán)時(shí)，i=1，
mystr[1]="小明:87"，
mystr[1].split(":")=["小明","87"]是一個(gè)數(shù)組，
mystr[1].split(":")[1] ="小明"，mystr[1].split(":")[1] ="小明"，mystr[1].split(":")[2] ="87"
而你說(shuō)的mystr[1].split(":",1)只取第一個(gè)字符串，所以這個(gè)數(shù)組的長(zhǎng)度為1，mystr[1].split(":",1)="小明"
3、所以這里應(yīng)該改為mystr[i].split(":")[2]
