The Javascript example requires support for JSON in browser, e.g. Firefox 3.5 can handle JSON. The example is quite simple, it invokes the thesaurus API with callback=process:

var s = document.createElement("script");
s.src = ""; // NOTE: replace test_only with your own KEY

function process(result) {
  output = "";
  for (key in result.response) {
    list = result.response[key].list;
    output += list.synonyms+"<br>";
  if (output)
    document.getElementById("synonyms").innerHTML = output;

Here is the live demo, that you will be able to see only on JSON capable browsers:

Synonyms of peace:
