我正在尝试向index.html文件中的按钮添加功能如下:我有一个按钮元素index.html

<button id="auth-button">Authorize</button>

在main.js应用程序中,我有

require('crash-reporter').start();
console.log("oh yaeh!");
var mainWindow = null;

app.on('window-all-closed', function(){
    if(process.platform != 'darwin'){
        app.quit();
    }
});

app.on('ready',function(){
    mainWindow = new BrowserWindow({width:800, height : 600});
    mainWindow.loadUrl('file://' + __dirname + '/index.html');

    var authButton = document.getElementById("auth-button");
    authButton.addEventListener("click",function(){alert("clicked!");});

    mainWindow.openDevTools();

    mainWindow.on('closed',function(){
        mainWindow = null;
    });
});

但是出现如下错误: Uncaught Exception: ReferenceError: document is not defined

在构建电子应用程序时是否可以访问DOM对象？或者是否有其他替代方法可以提供所需的功能？

当我在代理网络中时,我在cmd中设置了代理设置,如下所示:

set http_proxy=http://username:pass@hostname:port

set https_proxy=https://username:pass@hostname:port

现在我在普通网络上,我想在命令提示符中取消设置代理设置.是否有任何直接命令可以让我直接为命令行取消设置http_proxy和https_proxy环境变量,而不是导航通过GUI删除它们？

当我尝试使用Ubuntu 15.04安装电子时

sudo npm install electron-prebuilt -g

这就是我得到的

/usr/local/bin/electron -> /usr/local/lib/node_modules/electron-prebuilt/cli.js

> electron-prebuilt@0.28.3 postinstall /usr/local/lib/node_modules/electron-prebuilt

SWI Prolog允许在非最低级别的顶级之前执行目标,如下所示

swipl -s consultingfile.pl -g start

但是,当具有非零arity的谓词指定如下时

swipl -s consultingfile.pl -g start(1)

它给出了一个错误

syntax error near unexpected token '('

如何将非零arity谓词作为最高级别之前的目标传递？

我想为Docker容器的子网设置IP自定义池。为此，我遵循了此停止的docker守护程序，删除了docker0接口并使用自定义NetworkId重新创建

systemctl stop docker
ip link del docker0

使用NetworkManager重新创建docker0虚拟网桥接口并将其打开。

ant@ant ~> nmcli con up <UID>
ant@ant ~> ip addr
111: docker0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc noqueue state DOWN group default qlen 1000
    link/ether 3e:ff:1b:ce:e4:a4 brd ff:ff:ff:ff:ff:ff
    inet 172.20.0.1/20 brd 172.20.15.255 scope global docker0
       valid_lft forever preferred_lft forever

现在，当我再次启动docker daemon时，

ant@ant ~> systemctl start docker
ant@ant ~> ip addr
111: docker0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc noqueue state DOWN group default qlen 1000
    link/ether 3e:ff:1b:ce:e4:a4 brd ff:ff:ff:ff:ff:ff

.pl扩展名为perl 的文件的默认文件类型.但是我经常使用prolog所以每次打开一个新文件时我都必须通过运行vim命令手动设置它

:set filetype=prolog

我尝试通过插入以下行来自动化它 ~/.vimrc

autocmd BufNewFile,BufRead *.pl set syntax=prolog

还尝试在.vim/ftdetect/pl.vim文件中插入此行是徒劳的.

如何将.pl文件设置为prolog类型而不是perl？

I have some docker containers running on my machine, one of them being container_1

I am able to access container_1's cli using

ant@ant~/D/m/l/db> docker exec -it container_1 bash
daemon@1997cc093b24:/$

This allows me to go to container_1's cli but with no write permissions. The following commands give a permission denied error

ant@ant~/D/m/l/db> docker exec -it container_1 touch test.txt
bash: test.txt: Permission denied
ant@ant~/D/m/l/db>docker exec -it container_1 bash
daemon@1997cc093b24:/$ touch test.txt
bash: test.txt: Permission denied

Also tried using --previleged option …
