JavaScript dynamically generates private variable accessors _javascript tips

Copy Code code as follows:

Creates a new user object that accepts an object with many attributes as a parameter
function User (properties)
{
Iterate through all the properties of the object and ensure that it is scoped correctly
for (var i in properties) {
(function (which) {
var p=i;
Creates a new reader (getter) for this property
which["Get" +p]=function () {
return properties[p];
};

Creates a new setup (setter) for this property
which["Set" +p]=function (Val)
{
Properties[p]=val;
};
}) (this);
}
}
Creates a new instance of the user object and passes an object with two attributes as a parameter
var user=new user ({name: "Bob", age:44});
Reading property values
Alert (User.getname ());
Setting property values
User.setage (23);
