语法
dateObj.toTimeString()
描述
Date
对象的实例引用一个具体的时间点。 调用 toString
方法以美式英语和人类易读的形式,返回日期对象的格式化字符串。在 SpiderMonkey 里,该字符串由日期部分(年月日)和其后的时间部分(时分秒和时区)组成。有时会需要获取时间部分的字符串,这可以由 toTimeString
方法完成。
The toTimeString
method is especially useful because compliant engines implementing ECMA-262 may differ in the string obtained from toString
for Date
objects, as the format is implementation-dependent; simple string slicing approaches may not produce consistent results across multiple engines.
例子

println(d.toString()); // prints Wed Jul 28 1993 14:39:07 GMT-0600 (PDT)
println(d.toTimeString()); // prints 14:39:07 GMT-0600 (PDT)
