Look at the code

The code is as follows Copy Code

<title>js practice</title>
<body>
<script src= "Script.js" ></script>
<div id = "main" >
<p>this is a very simple HTML page.</p>
<p>it ' s about as basic as they come. It has: </p>
<ul>
<li>an H1 tag</li>
<li>two paragraphs</li>
<li>an unordered list</li>
</ul>
</div>
<div id= "JavaScript" >
</div>
</body>


Only in Google browser this error, other IE series, ff,opera are normal.

Look for a reason, JS's

The code is as follows Copy Code
Document.body.appendChild (container);

is run before the body, this time, document.body does not exist, that is null, so document.body.appendChild will report the above error.

Solution:

Include the script code inside the <body></body> or put it behind the body tag to work properly.

Modified Code

The code is as follows Copy Code

<title>js practice</title>
<body>
<div id = "main" >
<p>this is a very simple HTML page.</p>
<p>it ' s about as basic as they come. It has: </p>
<ul>
<li>an H1 tag</li>
<li>two paragraphs</li>
<li>an unordered list</li>
</ul>
</div>
<div id= "JavaScript" >
</div>

<!--now it'll run after the above elements have been created-->
<script src= "Script.js" ></script>
</body>
