推荐答案
这是 Opera 中的一个已知错误.除了上述解决方法的想法外,您可能还想尝试以下方法:
This is a known bug in Opera. In addition to the above ideas for workarounds, you may want to play with something like this:
var clone=document.documentElement.cloneNode(true)
var win=window.open('about:blank');
win.document.replaceChild(clone, win.document.documentElement);
win.print();
我没有测试过这个,但它应该在弹出窗口中创建页面的副本并打印它,而不必从服务器第二次加载内容或丢失您可能想要打印的任何 DOM 修改.
I have not tested this but it should create a copy of the page in a popup window and print it, without having to load the content a second time from the server or loosing any DOM modifications you may want printed.
