1. In js, the official website of string to date is like this:

Date.parse(datestring)

Where datestring is a date string.

For example, see: http://www.w3school.com.cn/tiy/t.asp?f=jseg_parse

The parse() method parses a datetime string and returns the number of milliseconds since midnight on 1/1/1970 from the datetime.

Return value: The number of milliseconds between the specified date and time and midnight (GMT time) on 1/1/1970.

Second, the datestring string format problem.

When datestring=2017-02-16, the parsed result is:

Thu Feb 16 2017 08:00:00 GMT+0800 (China Standard Time)

code show as below:

<html>
<body>

<script type="text/javascript">

var d = new Date(Date.parse("2017-02-16"));
document.write(d)

</script>

</body>
</html>

It's 08:00:00 here , not 00:00:00, which should relate to the timezone.

When datestring=2017/02/16, the result of parsing is:

Thu Feb 16 2017 00:00:00 GMT+0800 (China Standard Time)

code show as below:

<html>
<body>

<script type="text/javascript">

var d = new Date(Date.parse("2017/02/16"));
document.write(d)

</script>

</body>
</html>

As can be seen from the above code, js string to date should pay attention to the format of the date string.

Three, string to date method:

/**
 * Date parsing, string to date
 * @param dateString can be 2017-02-16, 2017/02/16, 2017.02.16
 * @returns {Date} returns the corresponding date object
 */
function dateParse(dateString){
	var SEPARATOR_BAR = "-";
	var SEPARATOR_SLASH = "/";
	var SEPARATOR_DOT = ".";
	var dateArray;
	if(dateString.indexOf(SEPARATOR_BAR) > -1){
		dateArray = dateString.split(SEPARATOR_BAR);  
	}else if(dateString.indexOf(SEPARATOR_SLASH) > -1){
		dateArray = dateString.split(SEPARATOR_SLASH);
	}else{
		dateArray = dateString.split(SEPARATOR_DOT);
	}
	return new Date(dateArray[0], dateArray[1]-1, dateArray[2]); 
};
