是否可以在页面加载事件上更改按钮背景颜色,但到目前为止我根本找不到任何此类方法.如果不可能,那么我很乐意使用一些在页面加载后加载的预定义图像.

我尝试了以下内容,没有成功:

的script.js

// chrome.browserAction.setIcon("red.png");
chrome.browserAction.setIcon({path:'red.png'});

的manifest.json

{
  "name": "Domain Colors",
  "version": "1.0",
  "manifest_version": 2,
  "content_scripts": [{
      "matches": ["http://*/*"],
      "js": ["script.js"]
  }],
  "permissions": [ "tabs", "http://*/*" ],
  "browser_action": {
    "default_title": "Colry",
    "default_icon": "blue.png"
  }
}

我有一个名为frmMain的表单,其中我有以下功能:

public void openFullScreen(String id,String content)
{
    frmEditor Editor = new frmEditor();
    Editor.WindowState = FormWindowState.Maximized;
    Editor.Content = content;
    Editor.ID = id;
    Editor.ShowDialog();
}

在Editor.cs中我使用以下代码:

private void btnClose_Click(object sender, EventArgs e)
{
    Object content = browserEditor.Document.InvokeScript("getContent");
    if (content != null)
    {
        object[] args = new object[2];
        args[0] = content.ToString();
        args[1] = _id;
        AppDomain.CurrentDomain.SetData("EditorContent", args);
        this.Close();
        //browserEditor.Document.InvokeScript("setEditorContent",args)
    }
}

关闭frmEditor我想告诉frmMain frmEditor现在关闭了,知道我必须显示某个值.我该如何检查？

下面是我的代码。尽管我使用的是 Oracle 网站上提供的代码，但它显示行数据但不显示列名

JPanel panel = new JPanel(new GridLayout(1, 1));
            JTextField txtFilter = new JTextField("1234.56");
            //panel.add(txtFilter);
            //TableModel model = new BibTexModel();
           String[] columnNames = {
                            "First Name",
                            "Last Name",
                            "Sport",
                            "# of Years",
                            "Vegetarian"
             };
           Object[][] data = {
                {"Kathy", "Smith",
                 "Snowboarding", new Integer(5), new Boolean(false)},
                {"John", "Doe",
                 "Rowing", new Integer(3), new Boolean(true)},
                {"Sue", "Black",
                 "Knitting", new Integer(2), new Boolean(false)},
                {"Jane", "White",
                 "Speed reading", new Integer(20), new Boolean(true)},
                {"Joe", "Brown",
                 "Pool", new Integer(10), new Boolean(false)}
};
            JTable table = new …

正如它所说的。无论如何要在整个 DOM 中搜索特定文本，例如CAPTCHA单词？

我从网站获取价格格式:10.990,00这样没有意义.需要做什么才能成为10,990.00.我试过跟随,但它正在取代所有.

price = "10.990,00"
price = price.replace(',','.',1)
price = price.replace('.',',',1)

我究竟做错了什么？

所以我正在运行我的网站http://localhost:8080,下面是我的测试:

public function testExample() {
        $this->browse( function ( Browser $browser ) {
            $browser->visit( '/' )
                    ->assertTitle( 'Welcome to Mysite' );
        } );
    }

在运行时php artisan dusk,它会打开错误的URL http://localhost.如果我提到完整的URL然后它的工作原理.

如何让它打开正确的URL？

在Dockerfile我提到的音量如下:

COPY src/ /var/www/html/但不知何故,我的代码更改似乎不像以前只使用Docker.除非我删除Pods,否则它不会出现.如何同步？

我正在使用minikube.

webserver.yaml

apiVersion: apps/v1
kind: Deployment
metadata:
  name: webserver
  labels:
    app: apache
spec:
  replicas: 3
  selector:
    matchLabels:
      app: apache
  template:
    metadata:
      labels:
        app: apache
    spec:
      containers:
      - name: php-apache
        image: learningk8s_website
        imagePullPolicy: Never
        ports:
        - containerPort: 80

我正在研究基于Java的COM程序,当我以这种格式发送数据时它可以工作:

serialPort.writeBytes( new byte[] { (byte)3, (byte)0, (byte)0, 
                                    (byte)0, (byte)4, (byte)5} );

但是当我这样做的时候却没有,我在哪里做错了？

byte[] bcode = null;
bcode[0] = (byte)3;
bcode[1] = (byte)0;
bcode[2] = (byte)0;
bcode[3] = (byte)0;
bcode[4] = (byte)4;
bcode[5] = (byte)5;
serialPort.writeBytes(bcode);

我得到的例外。我所做的只是增加了池数

代码

 def parse(url):
  r = request.get(url)
POOL_COUNT = 75
with Pool(POOL_COUNT) as p:
    result = p.map(parse, links)

我struct在列表中插入一个变量。我能够检索循环中插入的项目，但不能检索单个值。我收到错误：

e.Value.name undefined (type interface {} is interface with no methods)

代码如下：

type Item struct {
    name  string
    value string
}
queue := list.New()
per := Item{name: "name", value: "Adnan"}
queue.PushFront(per)

for e := queue.Front(); e != nil; e = e.Next() {
    fmt.Println(e.Value.name)
}
