推荐答案

假设没有相同的原始政策受限制，您可以

Assuming there are no same originl policy constrains, you can clone the node

var elements = document.getElementById('main_iframe').contentDocument.querySelectorAll(".optdel, .optbold");
var editsummary = document.getElementById("opteditsum");

for (var i = 0, im = elements.length; im > i; i++) {
    editsummary.appendChild(elements[i].cloneNode(true));
