js驼峰写法转短横线格式

  1. 小写字母转大写

    var UP = function(s){
      return s.toUpperCase().split(' ').join('_')
    }
    
    UP('Hedge number')
    
  2. 将格式为 CONTRACT_NUM 转换为驼峰形式

    var upFirst = function(s){
    //   首字母大写
      var arrs = s.split('')
      arrs[0] = arrs[0].toUpperCase()
      return arrs.join('')
    }
    var D = function(s){
      var arr = s.toLowerCase().split('_')
      arr = arr.map(function(item,index){
        return index !== 0 ? upFirst(item) : item
      })
      return arr.join('')
    }
    
    D('CONTRACT_NUM')
    
  3. 删除对象属性

    var obj = { name : 'xxx'}
    delete obj.name
    console.log(obj.name)  //undefined
