table 合计功能

countTotal(arr, keyName) {

            let $total = 0;

            $total = arr.reduce(function (total, currentValue, currentIndex, arr){

                return currentValue[keyName] ? (total + currentValue[keyName]) : total;

            }, 0);

            return $total.toFixed(2);

   },

通过调用这个方法  第一个急需要处理的数组，第二个参数为需要合计的属性

 

 getlist () {

            var userToken = this.$cookie.get('token')

            this.$http({                  

                url: this.$http.adornUrl('/generator/laborworker/list2'),

                method: 'post',

                headers: {

                    'token': userToken

                },

                 data: JSON.stringify({

                    'page': this.page,

                    'limit': this.pageSize,

                    "name": this.keyword,

                    "status":this.status

                })

            }).then(({data}) => {

                this.list=data.page.list

                this.gz=this.countTotal(this.list,'salary') //工资

                this.yfgz=this.countTotal(this.list,'yfSalary') //应发工资

                this.qjkc=this.countTotal(this.list,'subMoney') //请假扣除工资

                this.sfgz=this.countTotal(this.list,'sfSalary') //实发工资

                this.wfgz=  this.yfgz-this.sfgz-this.qjkc //实发工资     

                console.log( this.list,789789)

                this.total=data.page.totalCount

                if (this.total <= 10) {

                    this.show = false

                } else {

                    this.show = true

                }

            })

        },
