javascript - 创建日期对象

Question

我的项目中有一个奇怪的问题。我正在尝试动态地将参数插入到 Date 对象构造函数中。这是我的代码:

from += fromYear + "," + fromMonth + "," + fromDay + "," + fromHour + "," + fromMinute;
to += toYear + "," + toMonth + "," + toDay + "," + toHour + "," + toMinute;

console.log(from);  //here is log value: 2012,8,25,9,22
console.log(to);   //another log: 2012,8,25,9,52

//Creating object               
var fromtime =  new Date(from);
var totime = new Date(to);

当我尝试提醒日期对象(totime 或 fromtime)时，出现错误:日期无效。我不知道如何通过它。你能帮我吗？

Answer 1

在您的示例中，from 是一个逗号分隔的字符串，而不是 Date 构造函数需要的一系列离散变量作为参数:

var fromtime =  new Date(fromYear, fromMonth, fromDay, fromHour, fromMinute);

(月份是从 0 开始的，因此您可能需要添加 1)
