Scripting for NS6 and IE5.5 takes special care to adhere to standards and good programming practices. Each browser acts differently for external scripts, and you must be careful to encapsulate your element-dependent executable within functions called onload. Netscape 6 is particularly sensitive to improperly nested HTML when executing dynamically loaded scripts. By following these best coding practices, and coding for the DOM, you can ensure your scripts will work for current and future generations of browsers.
- Properly Nest all HTML Tags
- Properly Close all HTML Tags
- Validate your HTML
- Validate your CSS
- Choose the appropriate DOCTYPE, if any
- Define onload handers within external files, or subsequent SCRIPT blocks
We've provided some test cases to illustrate the problems that we discussed, and also some workarounds.
