问题描述

我正在尝试在chrome上发送whatsapp web版本的短信。

解决方案

在打开对话时尝试此片段：

  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！）; 
 
函数triggerClick（）{
 var event = new MouseEvent（'click'，{
'view'：window，
'bubbles'：true，
'cancelable'：true 
}）; 
 document.querySelector（。icon.btn-icon.icon-send）。dispatchEvent（event）
} 
 triggerClick（）
  

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:

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

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?

Here is the screen recording :

解决方案

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()
