vueJS年月日时分秒只取时分秒

Question

后台返回数据——2022-03-07_15:57:40
想要15:57:40
怎么截取？

that.data.time_cl = val.time_cl
          for(let i=0;i<val.time_cl.length;i++){
            console.log(val.time_cl)//2022-03-07_15:57:40
            // that.data.time_cl = val.time_cl.split("-").splice(0,2);
            that.data.time_cl =right(val.time_cl,3)//right is not defined
            console.log(that.data.time_cl)
          }

Answer 1

let time = '2022-03-07_15:57:40';
let newTime = time.split('_')[1] // 15:57:40
