VaR S = + newdate ();

VaR S = +NewDate ();

The explanation is as follows: = + does not exist;

+ New date () is a thing;

+ Equivalent to. valueof ();

See the reply to add. gettime (), which also gets the number of milliseconds.

 
//Returns the number of milliseconds of the current time as the four results are the same.
Alert (+NewDate ());
Alert (+NewDate );
VaRS =NewDate ();
Alert (S. valueof ());
 

 
Alert (S. gettime ());
 

The following describes how to use js to obtain the time:

VaRMydate =NewDate ();

VaRA = mydate. tolocalestring ();

By the way, valueof has another usage:

The valueof () method returns the original value of a Boolean object.

If the object that calls this method is not Boolean, an exception typeerror is thrown.

 
VaRBoo =NewBoolean (False);
Document. Write (Boo. valueof ());
