推荐答案
我将亲自确保您手动输入的日期输入格式清晰，我更喜欢DD-MMM-YYYY，消除了所有歧义.另外，如果无法识别日期，请处理此错误(下面的代码将写出任何无效日期").
首先要做的是解析日期对象中的日期.
然后只需对date对象的valueOf执行相等性测试(根据javascript docs，valueOf的输出与toString相同).
I would personally ensure your date entry for manual entries is clear in the format expected, I prefer DD-MMM-YYYY, removes all ambiguity. Also, if the date is not recognised handle this error (the code below will write out any "invalid date").
The first thing to do, is parse the dates in a date object.
Then simply perform an equality test of the valueOf the date object (according to the javascript docs, valueOf output is the same as toString).

var d1 = new Date(Date.parse(Text1.value));
var d2 = new Date(Date.parse(Text2.value));
output.innerHTML = "D1 value is: " + d1.toUTCString() + "<br />" + "D2 value is: " + d2.toUTCString();
alert("Are the dates the same; " + (d1.valueOf() == d2.valueOf()));
}
