Hii, i am new Extjs user. I am using Extjs history for back and forward button of browser. it is working fine, but the updated query is showing in URL, i want it should be hidden, so user can not see the query string. I herewith some snap of code,
I am using following code.
when Id added in stack, it is also showing in url, i want it should not be.

Ext.History.add('home' + a2rm.historybtn.tokenDelimiter +'start-div')

Ext.History.on('change', function(token){
if(token)
{
//a2rm.frameset.contentUpdater.update(token);
var parts = token.split(a2rm.historybtn.tokenDelimiter);
var tabPanel = Ext.getCmp(parts[0]);
var tabId = parts[1];
//alert("token>>"+tabId + " a2rm.historybtn.gflag>>>" +a2rm.historybtn.gflag);
if (tabId == 'start-div')
{
a2rm.currentNodeId ='start-div';
Ext.getCmp('content-panel').layout.setActiveItem('start-div');
}
else if(!tabId.indexOf('report'))
{
a2rm.selected_detail_id = tabId;
//alert("we r in report" + tabId.indexOf('report'));
reportMenuListener(a2rm.selected_detail_id);
}
else
{
if(a2rm.historybtn.gflag)
{
a2rm.historybtn.gflag = false;
}
else
{
Ext.getCmp('content-panel').layout.setActiveItem(tabId + '-panel');
}
}
a2rm.selected_detail_id = tabId;
addupdatedetail();
}
else if (token == '')
{
//do nohing
}
else
{
// This is the initial default state. Necessary if you navigate starting from the
// page without any existing history token params and go back to the start state.
Ext.getCmp('content-panel').layout.setActiveItem('start-div');
a2rm.selected_detail_id ='start-div';
a2rm.currentNodeId ='start-div';
addupdatedetail();
}
});
