The JavaScript connection

  • JavaScript files contain file paths, just like HTML files. The paths can be broken when you use PHP to insert library files.
  • You can fix the problem by creating a JavaScript variable in each file containing the path to the Web root. That variable is added to the JavaScript code in the library files.
  • The JavaScript variable can have its value set by PHP.

  • You can fix it with root relative paths, but this makes your site less portable.
  • A better way it to create a variable on each page, giving the path from that page to the root of the site. Add that variable in the inserted files.
  • This gives you a big productivity win. You can change an entire site just by changing one inserted file.
