does the landlord call the same function?
seems to be a variable scope problem. Correction: the problem is that the same object is referenced. Change the
to a closure?

-supplement

that means that your previous function variable has been modified, and you can change it to a closure. Let him be a scope alone 

click: () => {
     _this = this
     // _this.scheduleName = params.row.name
     axios({
     method: 'post',
     url: '/get_schedule/',
     data: Qs.stringify({'schedule_start':params.row.name})
    }).then(function (response){
        (function(scheduleName){
          _this.percentClock[scheduleName] = setInterval('_this.test1(scheduleName)', 3000) 
        })(params.row.name)
    })
   }

-modify
if you write setInterval ('_ this.test1 (scheduleName)', 3000)
parameter scheduleName, he will read this.scheduleName; 

click: () => {
     _this = this
     var scheduleName = params.row.name;
     
     let scheduleName = params.row.name;
     axios({
     method: 'post',
     url: '/get_schedule/',
     data: Qs.stringify({'schedule_start':params.row.name})
    }).then(function (response){
          _this.percentClock[scheduleName] = setInterval(()=>{
              _this.test1(scheduleName)
          }, 3000) 
    })
   }
what is equivalent to overwriting?
'_ this.test1 (_ this.scheduleName)' what is done in quotation marks?

should not be overwritten and executed. Please take a closer look. Even if the _ this.percentClock [_ this.scheduleName] name is the same, there will be no overwriting, and once it starts, it won't end. The same will not be overwritten, only manual clearInterval will end

Previous: Is it feasible to handle async await errors in this way?

Next: Mini Program canvas level is too high, how can it be covered?
