 sum += parseInt(self.checkboxModel[x].split(&#39;-&#39;)[1])
 }
 self.wodeshi=sum;
 },0)
 // console.log(self.checkboxModel)
},
checkedAll: function() {
 var _this = this;
 if (this.checked) {//实现反选
 _this.checkboxModel = [];
 }else{//实现全选
 _this.checkboxModel = [];
 _this.list.forEach(function(z) {
 _this.checkboxModel.push(z.coach_id+&#39;-&#39;+z.amount);
 });
 }
 if(_this.checkboxModel.length==0){
 this.wodeshi=0;
 // console.log(_this.checkboxModel);
 }else {
 var self =this;
