Question

有没有什么办法可以让Firefox在我的扩展程序中调用JavaScript函数，只要它完成下载（传递下载文件的路径）？

复制/粘贴解决方案。享受

function DownloadFile(sLocalFileName, sRemoteFileName)
{
    var saveToDirectory = 'C:\\Users\\louis\\downloads\\';

    var chrome = require("chrome");

    var oIOService = chrome.Cc["@mozilla.org/network/io-service;1"].getService(chrome.Ci.nsIIOService)

    var oLocalFile = chrome.Cc["@mozilla.org/file/local;1"].createInstance(chrome.Ci.nsILocalFile);
    oLocalFile.initWithPath(saveToDirectory + sLocalFileName);

    var oDownloadObserver = {onDownloadComplete: function(nsIDownloader, nsresult, oFile) {console.log('download complete...')}};

    var oDownloader = chrome.Cc["@mozilla.org/network/downloader;1"].createInstance();
    oDownloader.QueryInterface(chrome.Ci.nsIDownloader);
    oDownloader.init(oDownloadObserver, oLocalFile);

    var oHttpChannel = oIOService.newChannel(sRemoteFileName, "", null);
    oHttpChannel.QueryInterface(chrome.Ci.nsIHttpChannel);
    oHttpChannel.asyncOpen(oDownloader, oLocalFile);    

}
DownloadFile("saveAsThis.mp3","http://domain.com/file.mp3");
