      1. JavaScript常用工具方法封装

         更新时间:2019年02月12日 10:08:16   作者:周小肆   我要评论

        今天小编就为大家分享一篇关于JavaScript常用工具方法封装,小编觉得内容挺不错的,现在分享给大家,具有很好的参?#25216;?#20540;,需要的朋友一起跟随小编来看看吧

        因为工作中经常用到这些方法,所有便把这些方法进行了总结。

        JavaScript

        1. type 类型判断

        isString (o) { //是否字符串
          return Object.prototype.toString.call(o).slice(8, -1) === 'String'
        }
        isNumber (o) { //是否数字
          return Object.prototype.toString.call(o).slice(8, -1) === 'Number'
        }
        isBoolean (o) { //是否boolean
          return Object.prototype.toString.call(o).slice(8, -1) === 'Boolean'
        }
        isFunction (o) { //是否函数
          return Object.prototype.toString.call(o).slice(8, -1) === 'Function'
        }
        isNull (o) { //是否为null
          return Object.prototype.toString.call(o).slice(8, -1) === 'Null'
        }
        isUndefined (o) { //是否undefined
          return Object.prototype.toString.call(o).slice(8, -1) === 'Undefined'
        }
        isObj (o) { //是否对象
          return Object.prototype.toString.call(o).slice(8, -1) === 'Object'
        }
        isArray (o) { //是否数组
          return Object.prototype.toString.call(o).slice(8, -1) === 'Array'
