剛剛開始自學 用網站的教學 我照她說的做了 可是還是不對 請問哪裡出問題了? // Declare a variable on line 3 called // myCountry and give it a string value. var myCountry = "TAIWAN"; // Use console.log to print out the length of the variable myCountry. console.log("myCountry".length); // Use console.log to print out the first three letters of myCountry. console.log("TAIWAN".substring(0,3)); 這是她顯示錯誤的地方 Oops, try again! It looks like you didn't log the length of myCountry to the console. 可是我不是有用length了? 感謝回答~ -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 203.213.89.161
