How to change slider value on dat.GUI and how to reset dat.GUI

Question

1) I'm working on a dat.GUI application on which I have 2 sliders. I want to reset one when the other is changed. For example :

 var FizzyText = function() {
   this.slider1 = 0;
   this.slider2 = 0;
};
var gui = new dat.GUI();
var text = new FizzyText();
var slider1 = gui.add(text, 'slider1', 0, 5);
var slider2 = gui.add(text, 'slider2', 0, 5);

slider1.onChange(function(value){
  console.log(value); 
  text.slider2 = 0; // this doesn't work
});

slider2.onChange(function(value){
  console.log(value);
  text.slider1 = 0; // this doesn't work
});

This is just an example but it is very important that the slider is reseted or set to its default value (in FizzyText).

The example above comes from https://workshop.chromeexperiments.com/examples/gui/#9--Updating-the-Display-Automatically where I can't automatically update the slider

2) I want to add a reset button in which all sliders will be reseted. But with the previous answer I'd be able to reset all values

Answer 1

I found the answer : gui.__controllers is and array of controllers. So I just added something like that :

var FizzyText = function () {
    this.slider1 = 0;
    this.slider2 = 0;
};
var gui = new dat.GUI();
var text = new FizzyText();
var slider1 = gui.add(text, 'slider1', 0, 5);
var slider2 = gui.add(text, 'slider2', 0, 5);

/* Here is the update */
var resetSliders = function (name) {
    for (var i = 0; i < gui.__controllers.length; i++) {
        if (!gui.__controllers.property == name)
            gui.__controllers[i].setValue(0);
    }
};

slider1.onChange(function (value) {
    console.log(value);
    resetSliders('slider1');
});

slider2.onChange(function (value) {
    console.log(value);
    resetSliders('slider2');
});
