date to timestamp in javascript
Is it possible in javascript to convert some date in timestamp ?
i have date in this format 2010-03-09 12:21:00
and i want to convert it into it开发者_高级运维s equivalent time stamp with javascript.
In response to your edit:
You need to parse the date string to build a Date
object, and then you can get the timestamp, for example:
function getTimestamp(str) {
var d = str.match(/\d+/g); // extract date parts
return +new Date(d[0], d[1] - 1, d[2], d[3], d[4], d[5]); // build Date object
}
getTimestamp("2010-03-09 12:21:00"); // 1268158860000
In the above function I use a simple regular expression to extract the digits, then I build a new Date object using the Date constructor with that parts (Note: The Date object handles months as 0 based numbers, e.g. 0-Jan, 1-Feb, ..., 11-Dec).
Then I use the unary plus operator to get the timestamp.
Note also that the timestamp is expressed in milliseconds.
+(new Date())
Does the job.
The getTime()
method of Date
object instances returns the number of milliseconds since the epoch; that's a pretty good timestamp.
