Well done Mr Már, from "treason" now we are back to reason.
Almost ;o)
Dare I say, the last nail in the coffin of the jQuert.fn.cond, might
be this :
jQuery('a').each(function(){
switch(x) {
case 1 : $(this).css({ color: 'blue' }): break ;
case 2 : $(this).css({ color: 'red' }): break ;
default :
$(this).css({ color: 'green' });
}
});
Unfortunately, for some, this is "too many keystrokes" ... And
peculiarly (then very young and rushed) Mr B. Eich forgot to make
result of the switch available, so this is not possible in
javascript :
$(this).css({ color:
switch(x) {
case 1 : 'blue' ; break ;
case 2 : 'red' ; break ;
default : 'green' ;
}
}) ;
Unless done like this :
eval(
'switch(x){ case 1: "blue"; break; case 2: "red"; break; default:
"green" } '
) ;
Which is somewhat clumsy. So some have concluded they "must help"
everyone with function simillar to this :
cond( x, 1, "blue", 2, "red", default, "green" ) ; // or call it
'my_switch'
Now the 'excitement' is high, because one can write this :
$(this).css({ color:
switch(x) {
cond( x, 1, "blue", 2, "red", default, "green" )
}
}) ;
For some this is "Awesome", while for some this is "obfuscation" . I
vote for ECMA5 to simply allow assignment with the 'switch'
statement :
//My ECMA5 proposal
var color = switch(x) { case 1: "blue"; break case 2: "red"; break
default: "green" } ;
