Here are some helper functions for Java Script

function addScript(url) {
   var script = document.createElement("script");
   script.src = url + '&t='+new Date().getMinutes();
   script.type = "text/javascript";
   document.getElementsByTagName("head")[0].appendChild(script);
}

// performs a contextual product search

function productSearch(version, applicationid, adspace, region, programs, minPrice, maxPrice, category, page, items, q, callback) {
     var url = 'http://api.zanox.com/json/' + version + '/products?applicationid=' + applicationid;
     if (adspace) url += '&adspace=' + adspace;
     if (region) url += '&region=' + region;
     if (programs) url += '&programs=' + programs;
     if (category) url += '&category=' + category;
     if (page) url += '&page=' + page;
     if (items) url += '&items=' + items;
     if (minPrice) url += '&minPrice=' + minPrice;
     if (maxPrice) url += '&maxPrice=' + maxPrice;
     if (callback) url += '&callback=' + callback;
     if (q) url += '&q=' + q;
     addScript(url);
}

          var zxAdList = document.getElementById('zxAdList'); //ID of a UL HTML element

          for (var i = 0; i < productItems.length; i++) {
               var productItem = productItems[i];

     var li = document.createElement("li");
     li.innerHTML = '<a href="' + link + '">' + content + '</a>';  
     itemContainer.appendChild(li);
}

// this would start the product search
productSearch('2009-02-01', '..your applicationId..', null, 'de', '660', 0, 1000, null, 0, 5, 'test', 'exampleProductHandler');
