How to convert date to timestamp in javascript

Method: 1. Use the getTime() method, the syntax is "time object.getTime()"; 2. Use the valueOf() method, the syntax is "time object.valueOf()"; 3. Use parse() Method, syntax "parse(time object)".

The operating environment of this tutorial: windows7 system, javascript version 1.8.5, Dell G3 computer.

js string conversion timestamp can use the built-in function Date (time string to be converted) to first convert to Date type, and then convert the Date type to timestamp type, where the time string has requirements, The format must be in the form of yyyy-MM-dd HH:mm:ss. Of course, it can also be just yyyy-MM-dd, which is 2013-08-30, as follows:

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

1. var time1 = date.getTime( );

2.var time2 = date.valueOf();

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

The first and second types: will be accurate to milliseconds. The third type: can only be accurate to seconds. Milliseconds are replaced with 000. Note: Get The Unix timestamp can be obtained by dividing the arrived timestamp by 1000, and the value can be passed to the background to obtain it.
