本人剛剛開始自學js，本意是根據(jù)輸入提示框輸入的數(shù)字輸出一個乘法表，比如輸入1就輸出1*1=1....到1*9=9，輸入5就輸出5*5=25...到5*9=45?，F(xiàn)在不知道問題出在哪....<!DOCTYPE html> ?<html lang = "en"> ?<head><title>excercise1</title> ?</head> ?<body> <script> function chengfachart(chengshu0){??var chengshu0 = parseFloat(prompt("enter chengshu","1")); ??var chengshu1 = chengshu0; ??for(var chengshu1 = chengshu0;chengshu1 <= 8;chengshu1++); ??{ ??var deshu = chengshu1*chengshu0; ??document.write(chengshu1+"\*"+chengshu0+"\="+deshu+"<br/>"); ??} } ??chengfachart() ;</script> ?</body> ?</html>

	for(var?chengshu1?=?chengshu0;chengshu1?<=?9;chengshu1++){??//這里多了個分號
