I used to like some small unobtrusive links to the various W3C html and css validators at the bottom of my pages. Instead of mainting these links by hand I decided to write some litte Java for the task. The solution I came up with is W3C compliant in that browsers not capable of Javascript simply won’t display the links.

Here is the code for the Java function which I placed in the validator.jsfile:

    function validator()
    { 
          var url = 'Check this page for ' +
                    '<a href="http://validator.w3.org/checklink?uri=' +
                    location.href + "'>dead links</a>, ' +
                    '<a href="http://validator.w3.org/check?uri=' +
                    location.href + '">sloppy html</a>, or a ' +
                    '<a href="http://jigsaw.w3.org/css-validator/validator?uri=' +
                    location.href + '">bad style sheet</a>.';
          document.write(url);
    }

The function is included in the html page by placing the following between the <head> and </head> tags:

<script src="validator.js" type="text/javascript"></script>

Now that this function is available in the page, it is used on the page by placing this code in the body of the page:

<script type="text/javascript">
    <!-- // For browsercompatibility
    validator();
     // -->
</script>
