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-pickerv-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("");
}
