How to get month from string in javascript?

Question

I have tried

     var d=new Date("2012-07-01 00:00:00.0");
     alert(d.getMonth());   

But getting NAN.

I want month as July for the above date.

Answer 1

Try this:

    var monthNames = ["January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December"]
    var str="2012-07-01";   //Set the string in the proper format(best to use ISO format ie YYYY-MM-DD or YYYY-MM-DDTHH:MM:SS)
    var d=new Date(str);  //converts the string into date object
    var m=d.getMonth(); //get the value of month
    console.log(monthNames[m]) // Print the month name

NOTE: The getMonth() returns the value in range 0-11.

Another option is to use toLocaleString

var dateObj = new Date("2012-07-01");
//To get the long name for month
var monthName = dateObj.toLocaleString("default", { month: "long" }); 
// monthName = "November"

//To get the short name for month
var monthName = dateObj.toLocaleString("default", { month: "short" });
// monthName = "Nov"
