一个有趣的方法是通过dataset属性。

函数camelize(dashString) { let el = document.createElement('div') el.setAttribute(数据——+ dashString”) 返回种(el.dataset) [0] ｝ camelize('x-element') // 'xElement'

Lodash可以很好地做到这一点:

var _ = require('lodash');
var result = _.camelCase('toto-ce héros') 
// result now contains "totoCeHeros"

虽然lodash可能是一个“大”库(~4kB)，但它包含了许多通常使用代码片段或自己构建的函数。

以下所有14个排列产生相同的“equipmentClassName”结果。

String.prototype.toCamelCase = function() { return this.replace(/[^a-z ]/ig, '') // Replace everything but letters and spaces. .replace(/(?:^\w|[A-Z]|\b\w|\s+)/g, // Find non-words, uppercase letters, leading-word letters, and multiple spaces. function(match, index) { return +match === 0 ? "" : match[index === 0 ? 'toLowerCase' : 'toUpperCase'](); }); } String.toCamelCase = function(str) { return str.toCamelCase(); } var testCases = [ "equipment class name", "equipment class Name", "equipment Class name", "equipment Class Name", "Equipment class name", "Equipment class Name", "Equipment Class name", "Equipment Class Name", "equipment className", "equipment ClassName", "Equipment ClassName", "equipmentClass name", "equipmentClass Name", "EquipmentClass Name" ]; for (var i = 0; i < testCases.length; i++) { console.log(testCases[i].toCamelCase()); };

这个方法似乎比这里的大多数答案都要好，虽然有点粗糙，没有替换，没有正则表达式，只是建立一个新的字符串，那就是camelCase。

String.prototype.camelCase = function(){
    var newString = '';
    var lastEditedIndex;
    for (var i = 0; i < this.length; i++){
        if(this[i] == ' ' || this[i] == '-' || this[i] == '_'){
            newString += this[i+1].toUpperCase();
            lastEditedIndex = i+1;
        }
        else if(lastEditedIndex !== i) newString += this[i].toLowerCase();
    }
    return newString;
}

简单容易理解这段代码，希望这对你有帮助，我用下面的逻辑解决了我的问题

// This example is for React Js User

const ConverToCamelCaseString = (StringValues)=> 
{
    let WordsArray = StringValues.split(" ");
    let CamelCaseValue = '';
    for (let index = 0; index < WordsArray.length; index++) 
    {
        let singleWord = WordsArray[index];
            singleWord.charAt(0).toUpperCase();
            singleWord =singleWord.charAt(0).toUpperCase() + singleWord.slice(1);

        CamelCaseValue +=" "+singleWord;
        
    }
    CamelCaseValue = CamelCaseValue.trim();
    return CamelCaseValue;
}

下面的例子是针对核心javaScript用户的

function ConverToCamelCaseString (StringValues) 
    {
        let WordsArray = StringValues.split(" ");
        let CamelCaseValue = '';
        for (let index = 0; index < WordsArray.length; index++) 
        {
            let singleWord = WordsArray[index];
                singleWord.charAt(0).toUpperCase();
                singleWord =singleWord.charAt(0).toUpperCase() + singleWord.slice(1);

            CamelCaseValue +=" "+singleWord;
            
        }
        CamelCaseValue = CamelCaseValue.trim();
        return CamelCaseValue;
    }

console.log(ConverToCamelCaseString("this is my lower case string")); 

我希望上面的例子能解决你的问题。

可靠的高性能示例:

function camelize(text) {
    const a = text.toLowerCase()
        .replace(/[-_\s.]+(.)?/g, (_, c) => c ? c.toUpperCase() : '');
    return a.substring(0, 1).toLowerCase() + a.substring(1);
}

情况下,修改字符:
