我用的是element-ui ，下拉框回车的时候，不会隐藏option。所以在setTimeout前面加上了

  let select = document.getElementsByClassName("el-select-dropdown")
  for (let j = 0; j < select.length; j++) { select[j].style.display = "none" }

注意：打开控制台的时候，这个没作用，查了很久，查不出为什么，就很气！

 mounted() {
    let that = this
    document.addEventListener("keydown", function inputClick(e) {
      switch (e.key) {
        case "Enter":
          e.preventDefault();
          that.$nextTick(() => {
            let inputs = document.getElementsByTagName("input");
            for (let i = 0; i < inputs.length; i++) {
              if (e.target == inputs[i]) {
                  setTimeout(() => {
                  e.target.blur()
                  inputs[i + 1].focus();
                  // inputs[i + 1].select();
                  that.$forceUpdate()
                }, 500)
                break;
              }
            }
          })
          break;
      }
    }, !1)
  },
  beforeDestroy() {
    document.removeEventListener("keydown", inputClick(), false)
  },
