关于时间框 date.getHours is not a function 报错问题解决

1.可以发现，页面上选择的只有日期，但是代码中却有 HH:mm:ss

value-format="yyyy-MM-dd HH:mm:ss"

2.而且代码中

type="date"

3.date.getHours is not a function应该与此有关

解决方案：

删除HH:mm:ss

经验证，可以正常的选择日期了。

.

拓展:

 如果想要 type="date" 页面上只展示日期 ,而向后端发送的时候是 yyyy-MM-dd HH:mm:ss 这种格式的话

 <el-date-picker
      :disabled="disabledFields.includes('battery_factory_date') && isRequired"
      class="common-datetime-picker no-close"
      popper-class="common-datetime-picker-select"
      type="date"
      placeholder="请选择"
      v-model="form.battery_factory_date"
      :picker-options="setDisabled"
      @change="getdatatime()"
  />

需要引入:

import { parseTime} from "@/utils/index";

utils/index文件

/**
 * Parse the time to string
 * @param {(Object|string|number)} time
 * @param {string} cFormat
 * @returns {string | null}
 */
export function parseTime(time, cFormat) {
  if (arguments.length === 0 || !time) {
    return null
  }
  const format = cFormat || '{y}-{m}-{d} {h}:{i}:{s}'
  let date
  if (typeof time === 'object') {
    date = time
  } else {
    if ((typeof time === 'string')) {
      if ((/^[0-9]+$/.test(time))) {
        // support "1548221490638"
        time = parseInt(time)
      } else {
        // support safari
        // https://stackoverflow.com/questions/4310953/invalid-date-in-safari
        time = time.replace(new RegExp(/-/gm), '/')
      }
    }

    if ((typeof time === 'number') && (time.toString().length === 10)) {
      time = time * 1000
    }
    date = new Date(time)
  }
  const formatObj = {
    y: date.getFullYear(),
    m: date.getMonth() + 1,
    d: date.getDate(),
    h: date.getHours(),
    i: date.getMinutes(),
    s: date.getSeconds(),
    a: date.getDay()
  }
  const time_str = format.replace(/{([ymdhisa])+}/g, (result, key) => {
    const value = formatObj[key]
    // Note: getDay() returns 0 on Sunday
    if (key === 'a') {
      return ['日', '一', '二', '三', '四', '五', '六'][value]
    }
    return value.toString().padStart(2, '0')
  })
  return time_str
}

methods 中 :

   getdatatime(value) {   
      if (value == '') {
        this.form.battery_factory_date= "";
      } else {
        this.form.battery_factory_date =
          parseTime(this.form.battery_factory_date, "{y}-{m}-{d}") + " 00:00:00";
      }    
    },
