There's a pit---JS date format yyyy-mm-dd and YYYY/MM/DD

There is a hole here,---------each of the pits are summed up after a fortune.

When we write scripts, it is common to define a date format that uses both "2015-12-21" and "2015/12/21" data formats, since the picking date format is not good or bad. However, when we use the following statement to convert the date format, please note the following questions.

1, var dtnow=new Date (' 2015-12-21 ');

2, var dtnow=new Date (' 2015/12/21 ');

When we use the Chorme browser, we will find that both methods can be accurately converted to the desired date format. But when we are in the IE browser, the scenario one is wrong. Because IE does not recognize "-" as the format of the date. So the conversion will fail. It is best to use scenario two in the form of a date format.
