XHTML with JavaScript

Let's adjust our JavaScripts for validity in XHTML.

• Rules:

  1. type attribute (not the language attribute).
  2. lower-case letters for XHTML elements:
     • case sensitivity.
     • script tags.
     • event handler attributes.
  3. ampersand in external file.
  4. semantic mark-up language in external file.
  5. name attribute with the XHTML-transitional DTD.

• Validation Exercises:

  • Directions.
  • Exercise 1: error, upper-case letters, event handler.
  • Exercise 2: error, upper-case letters, another event handler.
  • Exercise 3: error, language attribute.
  • Exercise 4: error, upper-case letters for the type attribute.
  • Exercise 5: error, semantic mark-up language in a document level script.
  • Exercise 6: error, ampersands in a document level script.
  • Exercise 7: error, name attribute.

• Tasks.
