javascript日期格式不受支持-仍然需要该格式

Question

I need to compare dates but the finnish date format does not seem to be supported (thanks javascript!).

Here is the code that should return the difference between 2 dates (one of them being today):

function jämförMedIdag (datum) {
    if (datum == null || datum == "") {
        alert('Inget datum!');
        return;
    }
    var datum = new Date(datum);
    var dagar = datum.getDate();
    var månader = datum.getMonth();
    var år = datum.getYear();
    var nyttDatum = new Date();
    nyttDatum.setFullYear(år,månader,dagar);
    var idag = new Date();

    if(nyttDatum>idag) {
        var svar = nyttDatum - idag;
        return(svar);
    } else {
        var svar = idag - nyttDatum;
        return(svar);
    }
}

How can I tell javascript that my date is in format dd.mm.yyyy or dmyyyy or dd.m.yyyy or d.mm.yyyy?

Answer 1

JavaScript中没有像strptime这样的函数，因此您必须使用split或match这样的字符串操作函数strptime解析它。

Answer 2

Just parse it yourself:

var parts = datum.split('.');
datum = new Date();
datum.setFullYear(parts[2],parts[1]-1,parts[0]);

Etc.

Answer 3

If you don't want to write a parser from scratch you can give a try to Date.js , an open source library which has 150+ localized plugins. There's a Finnish version too.
