方法：进行互斥规则的校验

   // 规则互斥条件判断
change(val){
    if(this.dataList[1].isvalide==1 && this.dataList[0].isvalide==1){
        this.dataList[val].isvalide=0;
        this.$message({
           message: "规则互斥，不可以同时设置为有效",
           type: "warning",
            showClose: true,
         });
          return;
      }

        if(this.dataList[2].isvalide==1 && this.dataList[3].isvalide==1){
        this.dataList[val].isvalide=0;
        this.$message({
           message: "规则互斥，不可以同时设置为有效",
           type: "warning",
            showClose: true,
         });
         return;
      }


     if(this.dataList1[1].isvalide==1 && this.dataList1[0].isvalide==1){
        this.dataList1[val].isvalide=0;
        this.$message({
           message: "规则互斥，不可以同时设置为有效",
           type: "warning",
            showClose: true,
         });
          return;
      }

        if(this.dataList1[2].isvalide==1 && this.dataList1[3].isvalide==1){
        this.dataList1[val].isvalide=0;
        this.$message({
           message: "规则互斥，不可以同时设置为有效",
           type: "warning",
            showClose: true,
         });
         return;
      }

  
    
  console.log(val,"val---------");
},
 
 

juge方法：

juge(newList){
  
  let nary= newList.sort();
  console.log(nary,"nary--------------")
 j=1; 
  for(let i = 0;i<nary.length;i++){

    if(nary[i]==nary[i+1]){

       this.$message({
            message: "互斥外包商id输入重复,或者你的本行的外包商id输入重复",
            type: "error",
            showClose: true,
            duration:7000
          });
          j = 0;
    }
  }

},
