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?

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 */ }

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:

大写的“M”通常是最宽的。
Arial 30px在Chrome - W获胜。
我认为字母W是最宽的。
