Pass multiple values- Query string - Javascript

Question

Hi friends,

 

I have 2 values in 'A' page as below

string OppNumber = DataBinder.Eval(e.Row.DataItem, "OpportunityID").ToString();

string LeadNo = DataBinder.Eval(e.Row.DataItem, "Lead_no").ToString();

Now, I want to pass them to 'B' page in query string so I put the following code in 'A' page

HyperLink h5 = e.Row.FindControl("HypShowAllActivities") as HyperLink;

h5.Attributes.Add("OnClick", "fnDispAllActivities('" + OppNumber + ' ' + LeadNo + "')");

In design page of 'A' i added the following code

function fnDispAllActivities(OppNumber,LeadNo)

{

window.open('B.aspx?DocNo=' + OppNumber + '&LeadNo=' + LeadNo + '&Number=&ID=&Row=New', '', '', 'toolbars=0,resizable=1,scrollbars=0,width=800,height=600,top=0,left=0');

}

My requirement is to retrive the oppnumber,leadno seperately in 'B' page. Now,I can't get it them as seperatly,

But i have mistakes here.Can you Please help me to solve this?
