I am trying to send text messages on whatsapp web version on chrome.
(www.web.whatsapp.com)

This is the code:

document.getElementsByClassName(input)[1].innerHTML=This message was written via JS script! ;



var input = document.getElementsByClassName(icon btn-icon icon-send);

input[0].click();

But the problem is , initially when no text is present the input box looks like this:
enter

And only when I physically write some text it changes to this:

enter

And only now my script works since it requires the Send text button.

I tried Jquery code to simulate keypresses at $('.input)by following function:

function pressKey() {

  var e = jQuery.Event(keypress);

  e.which = 32; // # space

  $(.input).trigger(e)[1];

  e.which = 91;

  $(.input).trigger(e)[1];

  e.which = 32; // # space

  $(.input).trigger(e)[1];

  e.which = 32; // # space

  $(.input).trigger(e)[1];



}

It didn't work.

How can I get the Send text button by script?

Try this snippet, while opening a conversation:

function dispatch(target, eventType, char) {

   var evt = document.createEvent(TextEvent);    

   evt.initTextEvent (eventType, true, true, window, char, 0, en-US);

   target.focus();

   target.dispatchEvent(evt);

}





dispatch(document.querySelector(#compose-input div), textInput, hello!);



function triggerClick() {

  var event = new MouseEvent('click', {

    'view': window,

    'bubbles': true,

    'cancelable': true

  });

  document.querySelector(.icon.btn-icon.icon-send).dispatchEvent(event)

}

triggerClick()
