Javascript this

gistfile1.txt

this varies depending on the execution context and can sometimes lead to unexpected behaviour

ways of tackling this are:

newname = functionname.bind(object); // calling the bind method which exists on all JS functions creates a copy of the function
                                     // with this scoped to the value of the object passed into the bind method. 
newname(arg1,arg2);                  // newname will then need to be executed


                                    
functionname.call(object, arg1,arg2); // call executes the function but the first parameter is the object that you want to use for the this scop

functionname.apply(object, [arg1,arg2]); // its the same as call be it contains an array of arguments instead;
