Empty.js about locutus HOT 5 CLOSED

It throws an error. Only built-in typeof operator handles checks for non-existing variables in JavaScript, so the empty() function in phpjs has a limitation, which cannot be handled. In fact, the isset and empty in PHP are not real functions, they are language constructs, that look similar to functions, but have often "greater powers".

Rofl,

too bad.. I'm tired to use typeof blabla =='undefined' blabla

too long when i've 300000 test vars...

Well, PHP and JavaScript differ in many ways, so not everything can be ported from one to another. In PHP for instance there is no explicit variable declaration, so the isset/empty make sense. In JavaScript using undeclared variables leads to many problems, so you should just avoid such practices.

yep but when i try to access to an object parameter in my view and when the object is undefined. i must try the object first, next the params...etc

it's little complicated for nothing.

Not something we'll fix anyway, sorry.
