Show validation errors when calling validate() method

How can I show validation errors for inputs when calling validate() method?

---

I tried using editor.trigger("change") and set show_errors: "change", but it doesn’t work.

I added a setOption method. I don’t think I want to add a showErrors method at this time, but it should be easy enough to add yourself:

JSONEditor.prototype.showErrors = function() {
  this.setOption('show_errors','always');
}
JSONEditor.prototype.hideErrors = function() {
  this.setOption('show_errors','never');
}

To me show_errors controls automatic validation and errors visualization. validate() method makes on demand, application triggered validation possible (but without errors visualization).

What is missing is the on demand, application triggered validation and errors visualization.

I believe this is a typical workflow (@IonicaBizau please comment if this is more or less the same in your case):

1. User navigates to the configuration screen.
2. Several options are shown using JSON Editor, including editor for array of objects.
3. User adds additional (say third) object to the array by clicking “Add Item” button.
4. JSON Editor shows third object properties with default values set as expected. One field is empty (there is no default value) however according to the schema this one field cannot be empty to validate the JSON value.
5. User clicks “Save” button.

After step no.5 application has to trigger validation and show which field values are missing or incorrect.

This is what is missing right now and I still believe adding a new method for this purpose should not really complicate anything. Changing options to achieve this effect is a not the best solution in my opinion. It may be the way to implement the new method but I think it should be hidden from JSON Editor clients.
