我需要一件事，我需要检查一个日期，这是一个字符串在fomat dd / mm / yyyy 包含在两个日期之间，格式相同（dd / mm / yyyy ）

I need one thing, I need check if one date, that is a string in fomat dd/mm/yyyy is contained between two dates, with the same format (dd/mm/yyyy)

我尝试过这个，但不起作用：

I tried this, but doesn't work:

var dateFrom = "02/05/2013"; var dateTo = "02/09/2013"; var dateCheck = "02/07/2013"; var from = Date.parse(dateFrom); var to = Date.parse(dateTo); var check = Date.parse(dateCheck ); if((check <= to && check >= from)) alert("date contained");

我使用调试器和检查，变量和变量都有nNN值可以帮助我吗， 请？ 最好的问候，丹尼尔

I used debugger and check,to and from variables have isNaN value Could you help me, please? Best regards, Daniel

推荐答案

Date.parse 支持格式mm / dd / yyyy不是dd / mm / yyyy。为此，你必须使用一个图书馆，如moment.js，或者做一些如下面给出的内容。

Date.parse supports the format mm/dd/yyyy not dd/mm/yyyy. For that either you have to use a library like moment.js or do something as given below

var dateFrom = "02/05/2013"; var dateTo = "02/09/2013"; var dateCheck = "02/07/2013"; var d1 = dateFrom.split("/"); var d2 = dateTo.split("/"); var c = dateCheck.split("/"); var from = new Date(d1[2], parseInt(d1[1])-1, d1[0]); // -1 because months are from 0 to 11 var to = new Date(d2[2], parseInt(d2[1])-1, d2[0]); var check = new Date(c[2], parseInt(c[1])-1, c[0]); console.log(check > from && check < to)
