Tutorial Contents

In our notepad we will write the following:

<html>
<head>
</head>
<body>
<script language="javascript">
// todo el codigo se insertara aqui.
</script>
</body>
</html>

Inside <script language = "javascript"> </ script> we will write the following codes with which we will see our first message.

ALERT

  <script language="javascript"">
  alert("Hi @everyone!!!");
  </script>

"alert" shows an alert message, in this case, it shows this message: Hi @everyone !!!.

DOCUMENT.WRITE

 <script language="javascript">
  document.write('Hi @everyone!!!'+ '
');
  </script>

"Document.write" shows a message printed on the website on which we are working, with the same message: Hi @everyone !!!.

In this case, we will use the javascript outside of <script> </script> and we will use the code in the html directly, we will write it in the <body> </ body> using <button onClick = ""> with the sentences "alert" and "document.write":

<button onClick = "alert ('Hi @everyone !!!')"> click here! </ button>

<br><br>

<button onClick="document.write('Hi @everyone!!!')">click here!</button>
