为了仅仅资本化第一封信,并将其余的字符串下载案例:

function capitalize(str) {
     var splittedEnter = str.split(" ");
     var capitalized;
     var capitalizedResult;
     for (var i = 0 ; i < splittedEnter.length ; i++){
         capitalized = splittedEnter[i].charAt(0).toUpperCase();
         splittedEnter[i] = capitalized + splittedEnter[i].substr(1).toLowerCase();
    }
    return splittedEnter.join(" ");
}

capitalize("tHiS wiLL be alL CapiTaLiZED.");

结果将是:

这一切都将被资本化。

关于TypeScript

  capitalizeFirstLetter(string) {
    return string.charAt(0).toUpperCase() + string.slice(1);
  }

安装和加载Lodash:

import { capitalize } from "lodash";

capitalize('test') // Test

使用 Tailwind CSS

<p class="capitalize">The quick brown fox</p>

此分類上一篇: Quick Brown Fox

(src: https://tailwindcss.com/docs/text-transform#transforming-text)

优雅

const capitalize = ([firstChar, ...rest]) => `${firstChar.toUpperCase()}${rest.join('')}`;

let capitalize = (strPara)=>{
    let arr = Array.from(strPara);
    arr[0] = arr[0].toUpperCase();
    return arr.join("");
}

let str = capitalize("this is a test");
console.log(str);
