我正在尝试做一些基于句子中字符数量的动态规划。英语字母表中哪个字母在屏幕上占像素最多?

W获胜。
当然，这是一个愚蠢的经验实验。哪个字母最宽没有唯一的答案。这取决于字体。所以你必须做一个类似的经验实验来找出你所处环境的答案。但事实是，大多数字体遵循相同的惯例，大写W将是最宽的。
主旨与这些字符宽度的比率形式(W = 100)在这里捕获使用特定的示例字体:

其他回答
这取决于字体。例如，交叉0所占的空间要比普通0大得多。
但如果要猜的话，我会选X或B。

或者如果你想要一个宽度的映射，包含不止上面描述的alpha(数字)字符(就像我在非浏览器环境中需要的那样)
const chars = ["0", "1", "2", "3", "4", "5", "6", "7", "8", "9", "!", "\"", "#", "$", "%", "'", "(", ")", "*", "+", ",", "-", ".", "/", ":", ";", "=", "?", "@", "A", "B", "C", "D", "E", "F", "G", "H", "I", "J", "K", "L", "M", "N", "O", "P", "Q", "R", "S", "T", "U", "V", "W", "X", "Y", "Z", "[", "\\", "]", "^", "_", "`", "a", "b", "c", "d", "e", "f", "g", "h", "i", "j", "k", "l", "m", "n", "o", "p", "q", "r", "s", "t", "u", "v", "w", "x", "y", "z", "{", "|", "}", "~", " ", "&", ">", "<"] const test = document.createElement('div') test.id = "Test" document.body.appendChild(test) test.style.fontSize = 12 const result = {} chars.forEach(char => { let newStr = "" for (let i = 0; i < 10; i++) { if (char === " ") { newStr += " " } else { newStr += char } } test.innerHTML = newStr const width = (test.clientWidth) result[char] = width / 10 }) console.log('RESULT:', result) #Test { position: absolute; /* visibility: hidden; */ height: auto; width: auto; white-space: nowrap; /* Thanks to Herb Caudill comment */ }
想知道真正最长的字形，而不仅仅是猜测? 我说的不仅仅是字母、数字和常用符号(!， @等等)。我指的是UTF-16的32,834个字符中最长的字形。 所以我从@NK的回答开始，他有一个程序化的解决方案，并进行了修改:
var capsIndex = 65; var smallIndex = 97; var div = document.createElement('div'); div.style.float = 'left'; document.body.appendChild(div); var highestWidth = 0; var elem; for(var i = capsIndex; i < 32834; i++) { div.innerText = String.fromCharCode(i); var computedWidth = window.getComputedStyle(div, null).getPropertyValue("width"); if(highestWidth < parseFloat(computedWidth)) { highestWidth = parseFloat(computedWidth); elem = String.fromCharCode(i); } } div.innerHTML = '<b>' + elem + '</b>' + ' won';
在运行并等待(等待)之后，它给出输出won。 这就是UTF-32中最长的字符! 请注意，在大多数字体上，最长的字形是﷽，但有些字体(特别是单行字体)与运行程序时使用的字体重叠。
这段代码将获取数组中所有字符的宽度:
const alphabet = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ"; var widths = []; var div = document.createElement('div'); div.style.float = 'left'; document.body.appendChild(div); var highestObservedWidth = 0; // widest characters (not just one) var answer = ''; for (var i = 0; i < alphabet.length; i++) { div.innerText = alphabet[i]; var computedWidthString = window.getComputedStyle(div, null).getPropertyValue("width"); var computedWidth = parseFloat(computedWidthString.slice(0, -2)); // console.log(typeof(computedWidth)); widths[i] = computedWidth; if(highestObservedWidth == computedWidth) { answer = answer + ', ' + div.innerText; } if(highestObservedWidth < computedWidth) { highestObservedWidth = computedWidth; answer = div.innerText; } } if (answer.length == 1) { div.innerHTML = ' Winner: ' + answer + '.'; } else { div.innerHTML = ' Winners: ' + answer + '.'; } div.innerHTML = div.innerHTML ; // console.log(widths); // console.log(widths.sort((a, b) => a - b));
