end;

procedure TForm1.RzBitBtn6Click(Sender: TObject);
var

begin
ov:= WebBrowser1.OleObject.document.all.item('btnlogin', 0); {'btnlogin'代表网页上的按键名或ID}
ov.Click;

if SUCCEEDED(spDisp.QueryInterface(IHTMLAnchorElement ,iane))then
begin
if iane.href='http://www.nq51.com/' then //这里我在网页里的url是http://www.nq51.com调用的时候自动加上了'/'需要注意一下
