How to change a embeded grafana page‘s timerange without reload?

I have a parent page A,and a child page B,with same origin.

B is a garfana dashboard and is embeded in A with an iframe.

There is a timeRange selector in page A,I hope I can change grafana’s timerange with it.

But every time I push new src to my iframe,it reload.

How can i change timerange without reload? just like “setState“ in React.

Thanks a lot
