      },
      getCurPageContent: function(numberArr, curPage, itemNumPerPage){
        return numberArr.filter(function(element, index){
          if(index >= (curPage -1)* itemNumPerPage && index < curPage *itemNumPerPage){
            return true
          }else{
            return false
          }
        })
      },
      handleClick: function(arg){
        if(arg == 'leftBtn'){
          this.curPage = this.curPage > 1 ? --this.curPage : this.totalPage
        }else if (arg == 'rightBtn'){
          this.curPage = this.curPage < this.totalPage ? ++this.curPage: 1
        }
      }
      // handleLeftClick: function(){
      //   if(this.curPage > 1){
      //     this.curPage --
      //   }else{
      //     this.curPage = this.totalPage
      //   }
      // },
      // handleRightClick: function(){

      //   }
      // }
