Description

We needed this one for a project where Autocompleter should only request if some given input fields consists of special values. The only workaround was to change the "minChars" to an higher value so that the "onObserverEvent" wont be fired.

The more elegant version was to implement (patch) this behaviour by extending the Autocompleter.Base with a new Callback-Option:

The baseInitializer: 

this.options.onObserving = this.options.onObserving || 
function() { return true };

The event itself: 

onObserverEvent: function() {
    this.changed = false;   
    if(this.getToken().length>=this.options.minChars && this.options.onObserving()) {
      this.startIndicator();
      this.getUpdatedChoices();
    } else {
      this.active = false;
      this.hide();
    }
  },
