Rails spinoffs - Apr 2007 - Call function from outer class in an anonyme function

hello, i have a little problem...

in need to call a method of an outer class within a anonyme function.
here is my code example:

-- snip

var Test = Class.create();

Test.prototype = {
  test: function() {
    alert(''test!'');
  }

  query: function() {
    new Ajax.Request(...url..., {
      onSuccess: function(transport, json) {
        // call Test.test() here???
        Test.test();
      }
    });
  }
}

-- snip

I tried to write a method Test.queryOnSuccess(transport, json) which
is located in the same class and overwrites the anonyme function, but
this didn''t work either.

Can anybody tell me how to do this?

Thank you

Regards Christoph Hautzinger

Hey Christoph,

Classic binding issue:

Test.prototype = {
  test: function() {
    alert(''test!'');
  }

  query: function() {
    new Ajax.Request(...url..., {
      onSuccess: function(transport, json) {
        this.test();
      }.bind(this)
    });
  }
}
