elementui 开始结束时间可以选择同一天不同时间段

先在main.js中导入

import moment from 'moment'

  methods: {
      changeStartEnd(type, val) {
          debugger
    if (type === "start") {
        this.shiJuanXinXiForm.endTime = val
    }
},

}

computed: {
  isVisible: {
    get() {
      return this.dialogVisible;
    },
    set() {
      this.close();
      this.reset();
    },
  },
  title() {
    return this.$t("common." + this.type);
  },
    pickerOptions() {
        let str = "";
        if(this.$moment(this.shiJuanXinXiForm.startTime).format("YYYY-MM-DD") === this.$moment(this.shiJuanXinXiForm.endTime).format("YYYY-MM-DD")){
            str = this.shiJuanXinXiForm.startTime.split(" ").at(-1)
        }else{
            str = "00:00:00"
        }
        return {
            disabledDate: (time) => {
                return new Date(this.shiJuanXinXiForm.startTime).getTime() > time.getTime();
            },
            selectableRange: str + " - 23:59:59"
        }
    },
},
