i have a date in string like this: var myDateStr='1431451872338.00';
i want, getMonth() from this format date, i do:var date = new Date(myDateStr); but always return invalid date.
and the method getMont() always return NaN, if I put this: var date = new Date(1431451872338.00); this return the date correct but with my string not
my var myDateStr get the value from json and is variable, if someone can help me thank you very much in advance, i hope do understand
This works fine for me. You just need to be sure you're inputing a number, not a string.
var number = parseInt("1431451872338.00");
var date = new Date(number); //Tue May 12 2015 12:31:12 GMT-0500 (CDT)
var month = date.getMonth(); // 4
A Date object cannot be instantiated with a string. You better 1st transform your string into an Int and then ask for month:
var myDateStr='1431451872338.00';
var date = new Date(parseInt(myDateStr, 10));
alert(date.getMonth());
Could you use parseInt and do something like this:
var myDateStr = '1431451872338.00';
var myDateInt = parseInt(myDateStr, 10);
var myDate = new Date(myDateInt);
When you're passing in a date string to the javascript date object, it needs to be in the format "yyyy/mm/dd" or something like "January 10, 2014". What you're passing is the number of milliseconds since January 1, 1970, which is only accepted by the date object as a number. You need to change the type of your input variable.
Please make sure to research carefully before answering questions - the answer to your question is clearly stated on many date references like this one.
One Liner
var month = date.getMonth(Date(parseInt("1431451872338.00")));
new Date(Number(myDateStr))typeof NaN === "number"(Yes, Javascript is funny like that)Dateconstructor expects, the decimals.00are meaningless.typeof NaN === "123"
