ES6 map函数用不来，希望大佬可以帮忙用map帮忙转换一下这个if，想有个例子可以学习一下

for (let i = 0; i < this.dataSourecArry.length; i++) {
        if (this.dataSourecArry[i].checked) {
          if (this.dataSourecArry[i].label == "产废企业") {

            if (ps.length > 0) {
              this.addData(this.dataSourecArry[i].id, ps)

          }

        }
}

this.dataSourecArry.map(ceshi)

你这个代码是选择性的调用this.addData()。
map函数是返回一个与原数组长度一致的新数组，并不适用你这个情况。
 

你这个也就是把for循环改成 this.dataSourecArry.forEach()
 

1.循环

let checkedList = dataSourecArry.forEach(d=>{
    if(d.checked){

        let ps = this.getPs(d);

       if(ps && ps.length > 0){

         this.addData(d.id, this.ps)

       }        

    }else{
        this.$refs.actionDate[
            d.id
          ].cesiumObject.entities.removeAll()
    }
}) ;

你这个获得ps的地方，肯定有关联的关系。要么都用一个变量，要么定义对应关系。比如label，或者其他主键或者code

const psObj = {

''医疗废物'':ps1,

"***":ps2,

}

this.getPs=({label})=>{

return psObj[label] ;

}

上面的this.addData(d.id, this.getPs(d)) ;

//2.先筛选再循环

let noCheckedList = dataSourecArry.filter(a=>!a.checked) ;

noCheckedList.removeAll操作;

let result = dataSourecArry.filter(a=>a.checked && this.getPs(a)).map(a=>({data:d,ps:this.getWPs(a)})) ;

这种方式循环次数会变多，看实际情况。

最主要的那个映射对象做出来。后续再有其他对象，循环代码不用调整，只需要
