在javascript中将camel大小写转换为句子大小写

function camelToSentenceCase(camelCaseString) {
  // 将驼峰字符串拆分为单词
  var words = camelCaseString.match(/[A-Za-z][a-z]*/g) || [];

  // 将单词转换为句子大小写
  var sentenceCaseString = words.map(function(word) {
    return word.charAt(0).toUpperCase() + word.substr(1).toLowerCase();
  }).join(' ');

  return sentenceCaseString;
}
