IE6/7/8/9 does not support exec's shorthand _javascript skills

Source: Internet
Author: User
As follows
Copy Code code as follows:

var ary =/h/(' hello ');
alert (ary);

Error in IE6/7/8/9
The latest version of Firefox/safari/chrome/opera pops up "H"

The above wording is equivalent to
Copy Code code as follows:

var ary =/h/.exec (' hello ');

That is, the Exec method can be used in the Firefox/safari/chrome/opera browser to remove "exec" using the "regular direct amount + ()" method.
IE10 Platform Preview still does not support this shorthand.
