react jsx - Listen to keypress for document in reactjs

Question

I want to bind to close the active react bootstrap popover on escape press .Here is the code

_handleEscKey:function(event){
         console.log(event);
        if(event.keyCode == 27){
          this.state.activePopover.hide();
        }
   },

  componentWillMount:function(){
     BannerDataStore.addChangeListener(this._onchange);
     document.addEventListener("click", this._handleDocumentClick, false);
     document.addEventListener("keyPress", this._handleEscKey, false);
   },


   componentWillUnmount: function() {
     BannerDataStore.removeChangeListener(this._onchange);
      document.removeEventListener("click", this._handleDocumentClick, false);
      document.removeEventListener("keyPress", this._handleEscKey, false);
   },

But nothing is getting logged in the console when I press any key. I have tried to listen that on window also and with different cases .'keypress','keyup' etc but it seem I am doing something wrong .

Answer 1

You should use keydown and not keypress.

Keypress (deprecated) is usually used only for keys that produce a character output as per the docs

Keypress (deprecated)

The keypress event is fired when a key is pressed down and that key normally produces a character value

Keydown

The keydown event is fired when a key is pressed down.
