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。

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。

我认为这应该可行。
function cammelCase(str){
let arr = str.split(' ');
let words = arr.filter(v=>v!='');
words.forEach((w, i)=>{
words[i] = w.replace(/\w\S*/g, function(txt){
return txt.charAt(0).toUpperCase() + txt.substr(1);
});
});
return words.join('');
}
function convertStringToCamelCase(str){
return str.split(' ').map(function(item, index){
return index !== 0
? item.charAt(0).toUpperCase() + item.substr(1)
: item.charAt(0).toLowerCase() + item.substr(1);
}).join('');
}
我想出了这个内衬，它也适用于烤肉盒到骆驼盒:
string.replace(/^(.)|[\s-](.)/g,
(match) =>
match[1] !== undefined
? match[1].toUpperCase()
: match[0].toUpperCase()
)
我知道这是一个老答案，但这处理空格和_ (lodash)
function toCamelCase(s){
return s
.replace(/_/g, " ")
.replace(/\s(.)/g, function($1) { return $1.toUpperCase(); })
.replace(/\s/g, '')
.replace(/^(.)/, function($1) { return $1.toLowerCase(); });
}
console.log(toCamelCase("Hello world");
console.log(toCamelCase("Hello_world");
// Both print "helloWorld"
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()); };
