I am a beginner in the use of javascript and I am learning the handling of dom (very basic). I get this error in the console: Uncaught TypeError: Cannot read properties of null (reading 'setAttribute') I investigated how to fix it and tried it but I get the same result

    <!DOCTYPE html>
<html lang="es">
<head>
    <meta charset="UTF-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>DOM</title>
    <script src="/DOM/test.js"></script>
    <link rel="stylesheet" href="/DOM/index.css">
</head>
<body>
    <h1 id="titular">este es un titular</h1>
</body>
</html>

const titular = document.getElementById("titular"); titular.setAttribute("contentEditable","true");

  • Hi, Christopher, welcome to SO. Please give us more info, like where is placed that last line of code ? Maybe inside DOM/test.js ? You could post the content of the file where that last line is placed. It maybe a matter of timing: for instance, you must declare const titular *after* DOM is loaded. Otherwise, Javascript will not find an element if it isn't loaded yet... – quinqui Jun 04 '22 at 00:11
