How to Press the button with JavaScript.

function fnLoginPressEnter(obj) {
  if (this.event.keyCode == 13) {
    Ncucu.Login(document.forms[0]);
  }
} 

that's so wrong

webBrowser1.Document.InvokeScript("fnLoginPressEnter");

Answer 1

使用onkeydown =“ if（event.keyCode == 13）document.getElementById（'[YOUR_BUTTON_ID]'）。click（）”

Answer 2

If you using jQuery, you can do this:

$('#button_id').click();

or you can create manually an click event:

var el=document.getElementById('button_id');                            
if (!el.dispatchEvent) {
                            el.fireEvent('onclick');
                        } else {
                            var e = document.createEvent('MouseEvents');
                            e.initMouseEvent('click', false, true, top, 1, 0, 0, 0, 0, false, false, false, false, 0,
                                    null);
                            el.dispatchEvent(e);
                        }

Use this one with your requirement like onkeyup

eg:

onkeyup="javascript:KeyUp(event);"

function KeyUp(event)
var v = event.keyCode ? event.keyCode : event.charCode;
  if (v == "13") {
    document.getElementById('btnSubmit').click();
  }
