Hi David.
Sure... I make a library that that needs to share a private variable with
all methods
of an instance passed by arguments on my lib' method.
```
var lib;
(function () {
var shared;
shared = 'a shared value';
lib = {
method: function method(foreignObject) {
var property;
for (property in foreignObject) {
if (foreignObject.hasOwnProperty('property') {
if (typeof foreignObject === 'function') {
// how to pass the "shared" variable
// preserving the inside this in foreignObject
methods
// and without to touch the methods args?
}
}
}
}
};
}());```
The nearest way is something like this :
```
var foreignObject;
foreignObject = {
method: function method(shared) {
console.log(shared);
}
};
lib.method(foreignObject);
```
And, in place of the lib.method comments :
```
foreignObject[property] = foreignObject[property].bind(foreignObject,
shared);
```
It's really boring, because :
- it don't works with non-writable methods,
- it risks to loose the inside this of the methods (if not equal to
foreignObject),
- it forces to have a 'shared' arguments on each foreignObject method
Better? :)
