📚 探索未知领域:Web开发人员必备的14个超级书签! 🌐✨

大家好!今天我有一个超级酷炫的发现,它就是------书签!你可能好奇这是什么神奇的东西,不要着急,继续往下读,我将为你揭开这个神秘面纱!

什么是书签?

一个书签是一小段JavaScript代码,可以保存为浏览器中的书签。当点击这个书签时,它会在当前网页上执行JavaScript代码,执行特定的操作或增强页面的功能。它们真的很棒!那么,让我们看看如何制作一个吧!

如何制作书签

要将书签添加到浏览器中,请确保你可以看到书签栏。按照以下步骤添加一个书签:

  1. 右键单击书签栏,然后选择"添加网页"或类似选项;

  2. 将网址内容替换为 JavaScript 代码,如下所示:

    javascript 复制代码
    javascript:(function() {
      /*这里是你的代码*/
    })();

    上面的代码是一个JavaScript自执行函数。当你点击这个书签时,它就会执行。书签的好处在于它们可以与你所在的页面进行交互。不过,书签有一些重要的局限性!让我们看看下面的那些。

要记住的限制

以下是根据我的经验提供的一些提示,可帮助您创建有效且实用的书签:

  • 避免单行注释 :单行注释 ( //Comment ) 可能会有问题,并且难以在书签中进行故障排除。由于书签只有一行长,因此使用 // 方法可以有效地注释掉它后面的所有内容。请改用 /*Comment*/ 注释掉多行。
  • 注意跨域请求 :根据您的浏览器版本和设置,向 API 发出请求的书签可能具有 origin null 。在向书签中的 API 发出请求时,这有时会导致问题。
  • 最小化外部依赖关系 :不幸的是,在书签中包含像 <script src="https://url.com/"> 这样的外部依赖关系是不切实际的(有时是不可能的)。在编写代码时请记住这一点。
  • 考虑代码长度限制:某些浏览器可能对书签中允许的字符数有限制。虽然我个人没有遇到过这种情况,但如果您怀疑代码可能超过字符限制,最好缩小或压缩代码。

考虑到这些因素,您就可以创建自己的书签了!因此,让我们从以下示例开始。

书签 1:二维码生成器

此书签使用免费的 API https://api.qrserver.com 。这是一个相对简单的代码,通过转到 API 链接,将当前页面 URL 输入到 ?data= (数据)参数中,为任何页面生成二维码。代码如下:

javascript 复制代码
javascript:(function() {  var url = encodeURIComponent(window.location.href);  var qrCodeUrl = "https://api.qrserver.com/v1/create-qr-code/?data=" + url;  window.open(qrCodeUrl, "_blank");})();

书签 2:翻译页面

此书签使用谷歌翻译来翻译您所在的任何页面。单击时,它会提示输入语言(双字母代码,例如"中文简体"→"zh-CN"),并打开翻译后的页面。代码如下:

javascript 复制代码
javascript:(function() {  var lang = prompt("Enter language code to translate to:", "en");  var translationUrl = "https://translate.google.com/translate?sl=auto&tl=" + lang + "&u=" + encodeURIComponent(window.location.href);  window.open(translationUrl, "_blank");})();

书签 3:深色模式

此书签会将页面转换为深色模式(或尝试)。它可能会破坏某些页面。

javascript 复制代码
javascript:(function() {var style = document.createElement('style');style.innerHTML = `* {color: white !important;background-color: #111000 !important;}`;document.head.appendChild(style);})();

书签 4:密码生成器

这个方便的书签会生成一个随机密码。系统会提示您输入长度,并生成密码。这个书签特别利用了非常方便的浏览器 API 占位符,如提示。

javascript 复制代码
javascript:(function() {  function generatePassword(length) {    var charset = 'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789_-+={}|:"?#$*';    var password = '';    for (var i = 0; i < length; i++) {      var randomIndex = Math.floor(Math.random() * charset.length);      password += charset.charAt(randomIndex);    }    return password;  }  var passwordLength = prompt("Enter password length:", "8");  var generatedPassword = generatePassword(passwordLength);  prompt("Generated Password:", generatedPassword);})();

书签 5:电子邮件复制

如果您像我一样,并且偏执于打错电子邮件,那么此书签适合您。将 you@example.com 替换为您的真实电子邮件。

javascript 复制代码
javascript:(function() {  const email = "you@example.com";  const dummyElement = document.createElement("textarea");  document.body.appendChild(dummyElement);  dummyElement.value = email;  dummyElement.select();  document.execCommand("copy");  document.body.removeChild(dummyElement);})();

书签 6:页字数

当您单击书签时,它会扫描页面并告诉您上面有多少个单词。

javascript 复制代码
javascript:(function() {  var text = document.body.innerText || document.body.textContent;  var words = text.trim().split(/\s+/).length;  alert("Word Count: " + words);})();

书签 7:SEO 技巧书签

功能不全,但我在其中放了 20 个 SEO 技巧来帮助您入门:

javascript 复制代码
javascript:(function() {  var pageUrl = window.location.href;  var tips = processDiagnosticData();  if (tips) {    alert('Page Diagnosis Tips:\n\n' + tips);  }  function processDiagnosticData() {    var tips = '';    var titleTag = document.querySelector('title');    if (!titleTag) {      tips += 'Title Tag is missing\n';    }    var metaDescriptionTag = document.querySelector('meta[name="description"]');    if (!metaDescriptionTag) {      tips += 'Meta Description is missing\n';    }    var headingTags = document.querySelectorAll('h1, h2, h3, h4, h5, h6');    if (headingTags.length === 0) {      tips += 'Heading Tags are missing\n';    }    var imgTags = document.querySelectorAll('img');    if (imgTags.length === 0) {      tips += 'Image Tags are missing\n';    }    var anchorTags = document.querySelectorAll('a');    if (anchorTags.length === 0) {      tips += 'Anchor Tags are missing\n';    }    var scriptTags = document.querySelectorAll('script');    if (scriptTags.length === 0) {      tips += 'Script Tags are missing\n';    }    var linkTags = document.querySelectorAll('link');    if (linkTags.length === 0) {      tips += 'Link Tags are missing\n';    }    var metaViewportTag = document.querySelector('meta[name="viewport"]');    if (!metaViewportTag) {      tips += 'Viewport Meta Tag is missing\n';    }    var canonicalTag = document.querySelector('link[rel="canonical"]');    if (!canonicalTag) {      tips += 'Canonical Tag is missing\n';    }    var robotsTag = document.querySelector('meta[name="robots"]');    if (!robotsTag) {      tips += 'Robots Meta Tag is missing\n';    }    var ogTags = document.querySelectorAll('meta[property^="og:"]');    if (ogTags.length === 0) {      tips += 'Open Graph Tags are missing\n';    }    var twitterTags = document.querySelectorAll('meta[name^="twitter:"]');    if (twitterTags.length === 0) {      tips += 'Twitter Card Tags are missing\n';    }    var altAttributes = document.querySelectorAll('img:not([alt])');    if (altAttributes.length > 0) {      tips += 'Alt Attributes are missing for some Images\n';    }    var formTags = document.querySelectorAll('form');    if (formTags.length === 0) {      tips += 'Form Tags are missing\n';    }    var inputTags = document.querySelectorAll('input');    if (inputTags.length === 0) {      tips += 'Input Tags are missing\n';    }    var textareaTags = document.querySelectorAll('textarea');    if (textareaTags.length === 0) {      tips += 'Textarea Tags are missing\n';    }    var buttonTags = document.querySelectorAll('button');    if (buttonTags.length === 0) {      tips += 'Button Tags are missing\n';    }    var tableTags = document.querySelectorAll('table');    if (tableTags.length === 0) {      tips += 'Table Tags are missing\n';    }    var metaCharsetTag = document.querySelector('meta[charset]');    if (!metaCharsetTag) {      tips += 'Charset Meta Tag is missing\n';    }    return tips;  }})();

书签 8:元素荧光笔

基本上,它会更改所有页面元素的颜色,因此您可以看到它们:只需单击一下即可向我显示页面布局。对于开发人员来说,它可以帮助我们发现页面的问题。

javascript 复制代码
javascript:(function(){  function getRandomColor() {    var letters = "0123456789ABCDEF";    var color = "#";    for (var i = 0; i < 6; i++) {      color += letters[Math.floor(Math.random() * 16)];    }    return color;  }  function getContrastingColor(color) {    var hex = color.slice(1);    var r = parseInt(hex.substr(0, 2), 16);    var g = parseInt(hex.substr(2, 2), 16);    var b = parseInt(hex.substr(4, 2), 16);    var yiq = (r * 299 + g * 587 + b * 114) / 1000;    return yiq >= 128 ? "#000000" : "#FFFFFF";  }  function applyRandomStyle(element) {    var randomColor = getRandomColor();    element.style.backgroundColor = randomColor;    element.style.color = getContrastingColor(randomColor);  }  var elements = document.getElementsByTagName("*");  for (var i = 0; i < elements.length; i++) {    applyRandomStyle(elements[i]);  }})();

书签 9:JSON 格式化程序

此书签设置 JSON API 响应的格式:

javascript 复制代码
javascript:(function() { function syntaxHighlight(json) { json = JSON.stringify(json, undefined, 4); json = json.replace(/&/g, '&amp;').replace(/</g, '&lt;').replace(/>/g, '&gt;'); return json.replace(/("(\\u[a-zA-Z0-9]{4}|\\[^u]|[^\\"])*"(\s*:)?|\b(true|false|null)\b|-?\d+(?:\.\d*)?(?:[eE][+-]?\d+)?)/g, function (match) { var cls = %27color: black;%27; if (/^"/.test(match)) { if (/:$/.test(match)) { cls = %27color: green;%27; } else { cls = %27color: darkorange;%27; } } else if (/true|false/.test(match)) { cls = %27color: red;%27; } else if (/null|-?\d+(?:\.\d*)?(?:[eE][+-]?\d+)?/.test(match)) { cls = %27color: purple;%27; } return %27<span style="%27 + cls + %27">%27 + match + %27</span>%27; }); } var contentType = document.contentType; if (contentType === "application/json") { var json = JSON.parse(document.body.innerText); var highlighted = syntaxHighlight(json); document.body.innerHTML = %27<pre>%27 + highlighted + %27</pre>%27; document.body.style.fontFamily = "Arial, sans-serif"; document.body.style.fontSize = "15px"; } else { alert("This page does not contain JSON."); }}());

书签 10:拾色器

在任何页面上打开颜色选择器,以便您可以将其用于 Web 开发内容。

javascript 复制代码
javascript:(function(){  var container = document.createElement('div');  container.style.position = 'fixed';  container.style.top = '10px';  container.style.right = '10px';  container.style.zIndex = '9999';  container.style.backgroundColor = 'white';  container.style.borderRadius = '10px';  container.style.padding = '10px';  container.style.boxShadow = '0 0 10px rgba(0, 0, 0, 0.3)';  container.style.display = 'flex';  container.style.alignItems = 'center';  var colorInput = document.createElement('input');  colorInput.type = 'color';  colorInput.style.width = '30px';  colorInput.style.height = '30px';  colorInput.style.marginRight = '10px';  var copyButton = document.createElement('button');  copyButton.textContent = 'Copy';  copyButton.style.padding = '5px 10px';  copyButton.style.marginRight = '10px';  copyButton.style.backgroundColor = '#4CAF50';  copyButton.style.color = 'white';  copyButton.style.border = 'none';  copyButton.style.borderRadius = '5px';  copyButton.style.cursor = 'pointer';  var closeButton = document.createElement('button');  closeButton.textContent = 'Close';  closeButton.style.padding = '5px 10px';  closeButton.style.backgroundColor = '#f44336';  closeButton.style.color = 'white';  closeButton.style.border = 'none';  closeButton.style.borderRadius = '5px';  closeButton.style.cursor = 'pointer';  copyButton.addEventListener('click', function() {    var color = colorInput.value;    var tempInput = document.createElement('input');    tempInput.value = color;    document.body.appendChild(tempInput);    tempInput.select();    document.execCommand('copy');    document.body.removeChild(tempInput);    alert('Color copied to clipboard: ' + color);  });  closeButton.addEventListener('click', function() {    container.remove();  });  container.appendChild(colorInput);  container.appendChild(copyButton);  container.appendChild(closeButton);  document.body.appendChild(container);})();

书签 11:桌面吸管

这个超级方便的书签让你不仅可以从页面上选择颜色,还可以从整个桌面上选择颜色!
