Question

我知道,出于安全原因,这并不容易实现,但是,如果火烧确实发生,就会有办法这样做。

请帮助,在本页的行文中引用一些文字,以取得某种效果。

Basically, I would like to achieve two functionality: 1. add jQuery to any web page automatically if not already exist. 2. when open certain address, call a method of that page to auto notify the server. (an ajax functionality of the page)

I have tried to inject on the body, no luck. tried to get the window object, which however do not have access to call the function.

试图将地点改变为:javascript:alert(试验注射);

许多.。

Answer 1

在阅读了某些正式文件和Grease Monkey的消息来源之后,我获得了基本上为我工作的以下方法。

希望能节省时间:

var appcontent = document.getElementById("appcontent");   // browser  
    if (appcontent) {
         appcontent.addEventListener("DOMContentLoaded", function (evnt) {
            var doc = evnt.originalTarget; 
            var win = doc.defaultView;
            var unsafeWin = win.wrappedJSObject;

            // vote.up is the function on the page s context
            // which is take from this site as example
            unsafeWin.vote.up(...);
         }, true);
    }
}

Answer 2

Greasemonkey。如果你正在开发自己的延伸功能,你可以使用Components.utils.evalInSand Box 。
