Preserved Topic: delete an Object (Page 1 of 1)

Sorry for my simple questions, but i'm still at the beginning of learning javascript.

How can i delete an object?

Not sure exactly what you're trying to accomplish. If you have object o, you can set its value to null:

var o = new Object;

o = null;

If I understand correctly, you want to take an object or variable that you've declared, and make it as though you never declared it. This can be done with the delete operator:

var myvariable = 3;
delete myvariable;

This gives the variable the "undefined" value, as though it had never existed in the first place.

One should know that the delete operator in JavaScript has very little to do with the delete operator in other languages, such as C++.

Now, that said, I've personally never had a use for this. Why don't you tell us more about what you're trying to do, because I suspect there may be a better way to solve the problem you're trying to solve.
