1.Old PrototypeJS Script:
var loc = document.location.pathname;
var tail = "webengine/generated/Init"
loc = loc.substr(0,loc.indexOf(tail));
var url = loc.concat("protect/RouterServlet?NAV_MENU=TRUE&GREEN_NAV=TRUE");
new Ajax.Request(url,{method:'get',onSuccess:function(request){
var elemAjxResp = request.responseText;
document.getElementById('com-navigation').innerHTML = elemAjxResp;;
}});
2. Use Dojo Ajax and dom operation;
require(["dojo/_base/xhr","dojo/dom","dojo/domReady!"],function(xhr,dom) {
xhr.get({
url: url,load: function(newContent) {
dom.byId("com-navigation").innerHTML = newContent;
},error: function() {
}
});
});
