el-date-picker 组件 监听输入的内容 并按照时间格式 格式化

这个时间选择组件在输入的时候是监听不到输入的值的，所以我们在外层再套个div，然后用获取焦点事件去操作dom

页面中

 <div id="inParkingData">
      <el-date-picker
            v-model="indateRange"
            size="small"
            value-format="yyyy-MM-dd HH:mm:ss"
            type="datetimerange"
            range-separator="-"
            start-placeholder="开始日期"
            end-placeholder="结束日期"
            :default-time="['00:00:00', '23:59:59']"
            @focus="inParkingDataFocus('inParkingData', indateRange)"
          >
      </el-date-picker>
</div>

js文件中

// 获取 dom 方法
export function gainFocus(e, data) {
  console.log(e, data, "==11==");
  var _self = this;
  var inDataInput = document.getElementById(e).getElementsByTagName("input")[0];
  var outDataInput = document
    .getElementById(e)
    .getElementsByTagName("input")[1];
  inDataInput.addEventListener("input", inTapEvent);
  outDataInput.addEventListener("input", outTapEvent);

  function inTapEvent() {
    console.log(inDataInput.value);
    setTimeout(() => {
      inDataInput.value = disposeData(inDataInput.value);
    }, 100);

    Vue.set(data, 0, inDataInput.value);
  }
  function outTapEvent() {
    setTimeout(() => {
      outDataInput.value = disposeData(outDataInput.value);
    }, 100);
    Vue.set(data, 1, outDataInput.value);
  }

  return data;
}

// 更改格式
function disposeData(str) {
  var value = str.split("");
  if (value.length == 4) {
    value.splice(4, 0, "-");
  }
  if (value.length == 7) {
    value.splice(7, 0, "-");
  }
  if (value.length == 10) {
    value.splice(10, 0, " ");
  }
  if (value.length == 13) {
    value.splice(13, 0, ":");
  }
  if (value.length == 16) {
    value.splice(16, 0, ":");
  }
  return value.join("");
}
