尝试使用 Puppetter 打印 PDF 时出现以下错误。我在网上找不到有关此错误的更多信息。这是否意味着该特定页面不支持 PDF，或者我的代码中是否有可以修改此设置的设置？任何帮助，将不胜感激。

export const create = async (dev: boolean = true) => {
        
        const username = process.env.USERNAME;
        const password = process.env.PASSWORD;
    
        const options = dev
            ? {
                    headless: false,
                    slowMo: 25, 
              }
            : {};
    
        const browser = await Puppeteer.launch(options);
        const page = await browser.newPage();
    
        await page.goto(LOGIN_URL, {
            waitUntil: "networkidle2",
        });
    
        await page.type(USERNAME_INPUT_ID, username);
        
        const passwordInputHandle = await page.$(PASSWORD_INPUT_ID);
        await passwordInputHandle.type(password);
        await passwordInputHandle.press("Enter");
    
        await page.pdf({ path: path.join(TEMP_FOLDER, "hn.pdf"), format: "a4" });
    
        await browser.close();
    };

需要帮助测试用户与mocha selenium webdriver的交互.不知道在哪里找到正确的方法来获取文本输入的值.尝试了getAttribute(),getText等各种变体.获取相同的错误:

TypeError: Object [object object] has no method 'getElementText'

这是我的代码:

var assert = require('assert'),
    fs = require('fs');

var webdriver = require('../node_modules/selenium-webdriver'),
    test = require('../node_modules/selenium-webdriver/testing'),
    remote = require('../node_modules/selenium-webdriver/remote');


test.describe('Google Search', function() {
  var driver;

  this.timeout(60000);

  test.before(function() {
    driver = new webdriver.Builder().
        withCapabilities(webdriver.Capabilities.chrome()).
        build();
  });

  test.it('should append query to title', function() {

    //setTimeout(done, 60000);

    driver.get('http://localhost:8080/devanagariTextField/index.html');

    driver.findElement(webdriver.By.id('textbox')).sendKeys('gaa');
    //driver.findElement(webdriver.By.name('btnG')).click();
    driver.wait(function() {
      return driver.getElementText('value').then(function(text) {
        console.log('TEXT: ' + text)
        return '??' === text;
      });
    }, 1000);
  });

  //test.after(function() { driver.quit(); });
});

我正在使用这个功能:

function playSound(file) {

MyAudio = new Audio(file);
MyAudio.play();

}

不幸的是,我很难找到适用于所有浏览器的文件类型.Mp3适用于Chrome,Safari,IE但不适用于FF和Opera,而.ogg文件似乎只适用于FF.

有什么建议来解决这个问题吗？我认为没有办法以编程方式检测正在使用哪个浏览器,然后播放相应的文件类型？任何建议/想法赞赏.谢谢.

我试图让java在一次点击后执行一个操作,然后在再次按下相同的按钮时执行另一个操作,无论点击之间有多长时间.这可能吗？这是我到目前为止所尝试的:

button.addMouseListener(new MouseAdapter() {
    public void mouseClicked(MouseEvent e) {
        if (e.getClickCount()%2 == 1) {
            System.out.println("You have clicked once");
        }

        if(e.getClickCount()%2 == 0){
            System.out.println("You have clicked twice");
        }
    }
});

这不是我想要的,因为按钮上似乎有一些计时器使它更像是双击.所以我显然使用了错误的方法或其他东西,但我不知道还有其他选择.我希望在第一次点击后再次点击鼠标的速度并不重要.希望有道理.非常感谢任何帮助,谢谢.

如何使用 Redux Toolkit RTK Query 将查询参数传递给 api？

import { createApi, fetchBaseQuery } from '@reduxjs/toolkit/query/react';

const baseUrl = 'xxxxxxx';

export const postsApi = createApi({
  reducerPath: 'posts',
  baseQuery: fetchBaseQuery({ baseUrl }),
  endpoints: (builder) => ({
    getPostsByYear: builder.query({
      query: (start, end) => { // Why is 'end' always undefined???
        return {
          url: 'posts/',
          params: { start, end },
        };
      },
    }),
    getPosts: builder.query({
      query: () => 'posts/',
    }),

    getPostByID: builder.query({
      query: (name) => `posts/${name}`,
    }),
  }),
});

export const { useGetPostsQuery, useGetPostsByYearQuery, useGetPostByIDQuery …
