I have this code on my website:
<div id="cse" style="width: 100%;">Loading</div>
<script src="//www.google.com/jsapi" type="text/javascript"></script>
<script type="text/javascript">
google.load('search', '1', {language : 'it'});
google.setOnLoadCallback(function() {
var customSearchControl = new google.search.CustomSearchControl('mybigbigbignumber');
customSearchControl.setResultSetSize(google.search.Search.LARGE_RESULTSET);
customSearchControl.draw('cse');
}, true);
</script>
<link rel="stylesheet" href="//www.google.com/cse/style/look/default.css" type="text/css" />
It works as expected: the Google search bar appears, and the search results appears in the lower box.
What I need is a "transparent" search action.
I mean passing the search terms throughout my form, to the google WebSearch service, and display result in a custom css-ized list made by me.
I ended up using some jQuery to hide the Google standard form and trigger its submission.
