Answer 1

document.querySelector('#iframeID').contentWindow
  .document.querySelector('#myForm1').submit();

Answer 2

From an old project.... 来自一个旧项目...

Put this in your iframe code (test.html): 将其放入您的iframe代码（test.html）：

function getElement(id) {
    return document.getElementById(id);
}

then access the element via 然后通过访问元素

var el = document.getElementById("iframeID").contentWindow.getElement(id);

You should be able to act on that element from there. 您应该可以从那里对该元素进行操作。
