从内部获取对象 <object> 在javascript中标记

Question

I have an HTML code with the following:

<object class="sis" id="sis1" type="text/html" data="sis/sis1.html"></object>

and in the imported file I have and <h2> I am trying to manipulate with JS, but I can figure out a way to select the element.

I've even tried: document.getElementById("sis1").getElementById("h2_id") but -> Uncaught TypeError: Object #<HTMLObjectElement> has no method 'getElementById'

Answer 1

你试过了吗？

document.getElementById('sis1').contentDocument.getElementById('h2_id');
