Problem: to open a new window with the select -option
Modify your handleSubmit function as follows:
function handleSubmit()
{
var form = _gel("moduleForm"),
elm = _gel("allQuery"),
selectElm = _gel("allSelect");
if (elm != "" && selectElm != "") {
var query = elm.value;
var searchUrl = selectElm.value;
if (query != "" && searchUrl != "") {
searchUrl += escape(query);
window.open(searchUrl, form.target || "_blank");
}
}
return false;
}
