显示 JavaScript 到期日期变量是过去、未来还是今天到期？

Question

我想在我的 JavaScript 应用程序中显示一些基于 Due Date 是 past due、in the future 或 due today 的不同数据

下面的代码非常适合显示 Due Date 是在未来还是从今天的日期到期。

它不能显示截止日期是否设置为今天的日期，所以我可以使用一些帮助来让这部分工作吗？

// Today's Date
var todayDate = new Date();

// Future Due Date
var futureDueDate = new Date("08/07/2015");

// Past Due Date
var pastDueDate = new Date("03/29/2015");

// Due Date Due Today!
var dueDateToday = new Date("05/27/2015");


// selected dueDate is in the future
if (futureDueDate < todayDate) {
    alert('Due date is past due from todays date!');
}else if (futureDueDate == todayDate) {
    alert('Task Due date is due today!');
}else{
    alert('Due date is in the future from todays date!');
}


// selected dueDate is in the past
if (pastDueDate < todayDate) {
    alert('Due date is past due from todays date!');
}else if (pastDueDate == todayDate) {
    alert('Task Due date is due today!');
}else{
    alert('Due date is in the future from todays date!');
}


// selected dueDate is in the past
if (dueDateToday < todayDate) {
    alert('Due date is past due from todays date!');
}else if (dueDateToday == todayDate) {
    alert('Task Due date is due today!');
}else{
    alert('Due date is in the future from todays date!');
}

最终目标是获取Due Date 和Today's Date 并更改我的DateTime 相对时间文本字符串的颜色，以显示红色 文本以表示今天到期和逾期到期日。显示未来设置的到期日期的绿色文本。

就像我下面的图片：

如果截止日期是从今天开始的未来日期，则显示绿色文本

如果到期日是 PAST DUE 或 DUE TODAY，则显示红色文本

Answer 1

if (dueDate.toDateString() == todayDate.toDateString()) {
    alert('Task Due date is due today!');
}
