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()); };

基本的方法是用匹配大写或空格的正则表达式分割字符串。然后再把碎片粘回去。技巧将处理各种方式的正则表达式分割是破坏/奇怪的浏览器。有人编写了一个库来解决这些问题;我去找找。

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。

function toCamelCase(str) {
  // Lower cases the string
  return str.toLowerCase()
    // Replaces any - or _ characters with a space 
    .replace( /[-_]+/g, ' ')
    // Removes any non alphanumeric characters 
    .replace( /[^\w\s]/g, '')
    // Uppercases the first character in each group immediately following a space 
    // (delimited by spaces) 
    .replace( / (.)/g, function($1) { return $1.toUpperCase(); })
    // Removes spaces 
    .replace( / /g, '' );
}

我试图找到一个JavaScript函数驼峰大小写字符串，并希望确保特殊字符将被删除(我有困难理解上面的一些答案正在做什么)。这是基于c c young的回答，添加了注释，并删除了$peci&l字符。

从上驼峰格式("TestString")到下驼峰格式("TestString")，而不使用正则表达式(让我们面对现实吧，正则表达式是邪恶的):

'TestString'.split('').reduce((t, v, k) => t + (k === 0 ? v.toLowerCase() : v), '');
