Document.write（variable.toDateString）;不工作

Question

document.write('test'); 

將工作，並打印'測試'的文件。

document.write(d.toDateString()); 

無所事事。 d當然是我的Date變量，但它並不是按照我的設想打印日期。可能是一個業餘的錯誤:(也是我想打印出這個日期在一個紅色的顏色，我該怎麼做？

編輯：我的完整代碼（我認爲毫秒的轉換是使其行爲規範，但我需要做的是如何轉換都回來什麼的）

Answer 1

最有可能d是不是一個真正的約會對象，但別的東西

試試這個：？

var d = new Date(); 
document.write("<span style=\"color: red;\">" + d.toDateString() + "</span>");
