Assuming you have access to that domain in the window you're opening (same origin policy), you have to wait for the window to finish opening first before accessing elements inside. 假设您可以在要打开的窗口中访问该域（相同的原始策略），则必须等待该窗口首先完成打开，然后才能访问其中的元素。
$("#buttonDownloadBRScan").click(function(){
const w = window.open('https://www.fdibr.com.br/autenticacao/autenticacao/login');
w.addEventListener('DOMContentLoaded', () => {
w.document.getElementById("usuario").innerHTML = "7478704";
});
})

Try something like this: 尝试这样的事情：
<input id="yourID" type="button" onclick="open_page()" value="Your Message Here"/>
<script>
function open_page () {
window.open('Your Webpage');
}
</script>

外部站点和内部站点具有不同的域，您不能直接从内部站点修改外部站点内容。可以使用window.postMessage，也许可以解决您的问题
