Question

chrome插件的contentscrip中怎么调用目标页面的函数？？？？？

Answer 1

var script = document.createElement('script');
script.type = 'text/javascript';
script.innerHTML = 'methodInOriginPage();'
document.body.appendChild(script);

Answer 2

不可以调用的。只能访问目标页面的 DOM，不能访问 JavaScript 变量和函数。

Content scripts execute in a special environment called an isolated world. They have access to the DOM of the page they are injected into, but not to any JavaScript variables or functions created by the page.
