Javascript-regexp objects can only be used once

The following code is a test that identifies the date from the string and can see the created RYMD this RegExp object runs once and runs once.

var datestr = "2014-9-8"; var rymd = new RegExp ("(\\d{4}|\\d{2})-(\\d{2}|\\d{1})-(\\d{2}|\\d{1})", "G"); var aRt = RYMD.exe C (DATESTR); var srt=rymd.exec (DATESTR);

After debugging, we found that the first run, art got the returned Array (array), but the SRT followed by IS null

After repeated attempts, it was discovered that the RegExp object was discarded once it was run.

Therefore, it is necessary to pay attention to the need to regexp each time to new one.
