#js string conversion timestamp can be converted first using the built-in function Date (the time string to be converted) It is a Date type, and then the Date type is converted into a timestamp type.

Here you will get a Date type data, to get the timestamp data, you need to operate the date object and convert the date into time There are three ways to stamp, as follows:

1. var time1 = date.getTime();

2.var time2 = date.valueOf();

3.var time3 = Date.parse(date);

First and second: yes Accurate to milliseconds. The third type: can only be accurate to seconds. Milliseconds are replaced by 000. Note: The obtained timestamp is divided by 1000 to obtain the Unix timestamp, which can be obtained by passing the value to the background.
