I have an object a:

var a = {//some properties....};

Then b refer a:

var b = a;
function modifyB()
{
//do something with b to change a
}
//after finish I want from b to refer an other object c
b = c;

The problem that a refer c , how can I change b without changing a after modifyB().

You need to make a copy of the object. – SLaks Nov 26 '15 at 18:29
If it's a simple object (ie no methods) you can do `var b = JSON.parse(JSON.stringify(a));` to do a quick clone. – Andy Nov 26 '15 at 18:58
can't use `JSON.parse` , because `a` contain methods. – WriteYour NameHere Nov 26 '15 at 19:16
