又修改了一下代码。但是还是打印不出来。

<!doctype html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Document</title>
</head>
<body>
    <script type="text/javescript">
        var j = 5;
        if ( j >= 0 && j <= 60 ) {
            console.log( "这是E" );
        } else if ( j > 60 && j <= 69 ) {
            console.log( "这是D" );
        } else if ( j > 69 && j <= 78 ) {
            console.log( "这是C" );
        } else {
            console.log( "超神" );
        }

    </script>
