如何使用javascript正则表达式将字符串转换为驼峰大小写?
设备类名称或 设备类名或设备类名或设备类名
应该全部变成:equipmentClassName。

遵循@Scott的可读性方法，做了一点微调
// convert any string to camelCase
var toCamelCase = function(str) {
return str.toLowerCase()
.replace( /['"]/g, '' )
.replace( /\W+/g, ' ' )
.replace( / (.)/g, function($1) { return $1.toUpperCase(); })
.replace( / /g, '' );
}

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()); };

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。
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'
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。
