Firefox Addon SDK - 如何创建about:页面

时间:2015-12-06 11:55:37

标签: firefox-addon firefox-addon-sdk about-box

我需要创建 about:页面,以显示插件选项。我以前见过ti,但SDK中似乎没有允许你这样做的选项。

我是否可以通过其他方式让用户输入关于:网页名称 并进入我的网页?

我不希望将所有带有about:pagename网址的标签重定向到其他选项页面。

提前致谢

这是使用index.js开发的无重启加载项的jpm文件:

const { Cc, Ci, Cr, Cu, Cm, components } = require("chrome");

Cm.QueryInterface(Ci.nsIComponentRegistrar);
Cu.import("resource://gre/modules/XPCOMUtils.jsm");
Cu.import("resource://gre/modules/Services.jsm");

// globals
var factory;
const aboutPage_description = 'This is my custom about page';
const aboutPage_id = '6c098a80-9e13-11e5-a837-0800200c9a66'; // make sure you generate a unique id from https://www.famkruithof.net/uuid/uuidgen
const aboutPage_word = 'foobar';
const aboutPage_page = Services.io.newChannel('data:text/html,hi this is the page that is shown when navigate to about:foobar', null, null);

function AboutCustom() {};

AboutCustom.prototype = Object.freeze({
    classDescription: aboutPage_description,
    contractID: '@mozilla.org/network/protocol/about;1?what=' + aboutPage_word,
    classID: components.ID('{' + aboutPage_id + '}'),
    QueryInterface: XPCOMUtils.generateQI([Ci.nsIAboutModule]),

    getURIFlags: function(aURI) {
        return Ci.nsIAboutModule.ALLOW_SCRIPT;
    },

    newChannel: function(aURI) {
        let channel = aboutPage_page;
        channel.originalURI = aURI;
        return channel;
    }
});

function Factory(component) {
    this.createInstance = function(outer, iid) {
        if (outer) {
            throw Cr.NS_ERROR_NO_AGGREGATION;
        }
        return new component();
    };
    this.register = function() {
        Cm.registerFactory(component.prototype.classID, component.prototype.classDescription, component.prototype.contractID, this);
    };
    this.unregister = function() {
        Cm.unregisterFactory(component.prototype.classID, this);
    }
    Object.freeze(this);
    this.register();
}

exports.main = function() {
  factory = new Factory(AboutCustom);
};

exports.onUnload = function(reason) {
  factory.unregister();
};

基本上,它会在您访问about:foobar时注册将加载的自定义页面。加载的页面只是一行文本。

这就是它的样子:

about:foobar page

如果您使用的是addons-sdk,我认为这是一个更好的解决方案:

信用到这里: https://stackoverflow.com/a/9196046/1038866

var pageMod = require("page-mod");
pageMod.PageMod({
  include: data.url("options.html"),
  ...
});    
var tabs = require("tabs");
tabs.open(data.url("options.html"));

但还有其他方法。您可以查看实现此功能的Scroll to Top插件:https://addons.mozilla.org/firefox/addon/402816
