Loading JavaScript in HTML

Use simple syntax to load external scripts (the type attribute is not required):

Access HTML elements

The consequence of using the "untidy" HTML style may be an JavaScript error.

These two JavaScript statements produce different results:

Var obj = getElementById ("Demo")

Var obj = getElementById ("demo")

If possible, use the same naming convention in HTML (just like JavaScript).

Access the HTML style Guide.

File extension

HTML files should use the .html extension (not .htm).

CSS files should use the .css extension.

JavaScript files should use the .js extension.

Use lowercase file names

Most web servers (Apache, Unix) are sensitive to the case of file names:

London.jpg cannot be accessed as a London.jpg.

Other web servers (Microsoft's IIS) are case-insensitive:

London.jpg can be accessed as London.jpg or london.jpg.

If you mix case, you must be strictly contiguous and consistent.

Even this small error can damage your site if you move your site from a case-insensitive server to a case-sensitive server.

To avoid these problems, always use lowercase file names, if possible.

Performance

Computers do not use code conventions. Most rules have little impact on the execution of the program.

Indentation and extra spaces are not important for small scripts.

For scripts under development, readability should be a priority. Larger production scripts should be scaled down.
