codesandbox 的 JS vanila 模板不起作用

Question

Attaching my code here. Trying to learn JS. Practicing my code in the codesandbox.io's vanilla JS template.

Error:

It is not reading the function that I am defining.

CODE:

<meta charset="utf-8">   

<title>BOM property</title>   

<h2>Browser Object Model (BOM) properties</h2>   

<script type="text/javascript">    

    function prpt()    

    {   

     document.write("The innerHeight is :"+window.innerHeight+"<br>"); //inner height   

     document.write("The innerWidth is :"+window.innerWidth); // inner width    

    }   

</script>      

<input type="button" value="innerHeight_Width" onclick="prpt()">      

Answer 1

Try to save the document with Ctrl + S keyword, and then execute the code.

Answer 2

This code seems to work:

 <h2>Browser Object Model (BOM) properties</h2> <script type="text/javascript"> // fixed some space's function prpt() { document.write("The innerHeight is:"+window.innerHeight+"<br>"); //inner height document.write("The innerWidth is:"+window.innerWidth); // inner width } </script> <input type="button" value="innerHeight_Width" onclick="prpt()">
