const toCamelCase = str =>
  str
    .replace(/[^a-zA-Z0-9]+(.)/g, (m, chr) => chr.toUpperCase())
    .replace(/^\w/, c => c.toLowerCase());

您可以使用以下解决方案:

String.prototype.toCamelCase = function(){ return this.replace(/\s(\w)/ig, function(all, letter){return letter. touppercase ();}) .replace (/ (^ \ w)、功能(1美元){返回1.美元tolowercase ()}); }; console.log(“设备名称”.toCamelCase ());

看看你的代码，你可以实现它只有两个替换调用:

function camelize(str) {
  return str.replace(/(?:^\w|[A-Z]|\b\w)/g, function(word, index) {
    return index === 0 ? word.toLowerCase() : word.toUpperCase();
  }).replace(/\s+/g, '');
}

camelize("EquipmentClass name");
camelize("Equipment className");
camelize("equipment class name");
camelize("Equipment Class Name");
// all output "equipmentClassName"

编辑:或者使用一个替换调用，捕获RegExp中的空白。

function camelize(str) {
  return str.replace(/(?:^\w|[A-Z]|\b\w|\s+)/g, function(match, index) {
    if (+match === 0) return ""; // or if (/\s+/.test(match)) for white spaces
    return index === 0 ? match.toLowerCase() : match.toUpperCase();
  });
}

这将把任何空格大小写字符串转换为thisWordsInCamelCase

function toCamelCase(str) {
  return str.toString() && str.split(' ').map((word, index) => {
    return (index === 0 ? word[0].toLowerCase() : word[0].toUpperCase()) + word.slice(1).toLowerCase()
  }).join('');
}

const toCamelCase = str =>
  str
    .replace(/[^a-zA-Z0-9]+(.)/g, (m, chr) => chr.toUpperCase())
    .replace(/^\w/, c => c.toLowerCase());

ES5

var camalize = function camalize(str) {
    return str.toLowerCase().replace(/[^a-zA-Z0-9]+(.)/g, function(match, chr)
    {
        return chr.toUpperCase();
    });
}

ES6

var camalize = function camalize(str) {
    return str.toLowerCase().replace(/[^a-zA-Z0-9]+(.)/g, (m, chr) => chr.toUpperCase());
}

> To get ***C**amel**S**entence**C**ase* or ***P**ascal**C**ase*

var camelSentence = function camelSentence(str) {
    return  (" " + str).toLowerCase().replace(/[^a-zA-Z0-9]+(.)/g, function(match, chr)
    {
        return chr.toUpperCase();
    });
}
