Show object tag content from a certain position

Question

I have an object tag that shows another website, now I want to show the content of the object from a certain position of the scroll, I tried with javascript but found nothing working. What do you suggest to do?

that is the HTML:

<object class="boxmeteo" id="bmeteo" type="text/html" data="https://www.3bmeteo.com/meteo/roma" >

JS:

<script>
    document.getElementById("bmeteo").scroll(0,150);
</script>
