element ，vantUI寫數據加載延時出現loading

element:

let loading;
// 出現請求過慢時loading出現
var clearSettimeout;
function startLoading() {
  clearSettimeout = setInterval(() => {
    loading = Loading.service({
      lock: true,
      text: "努力加載中……",
      background: "rgba(0, 0, 0, 0.1)"
    });
  }, 3000);
}
function endLoading() {
  clearTimeout(clearSettimeout);
  clearSettimeout = null;
  if (loading) {
    loading.close();
  }
}
// loading互不衝突調用
let needLoadingRequestCount = 0;

export function showFullScreenLoading() {
  if (needLoadingRequestCount === 0) {
    startLoading();
  }
  needLoadingRequestCount++;
}

export function tryHideFullScreenLoading() {
  if (needLoadingRequestCount <= 0) return;
  needLoadingRequestCount--;
  if (needLoadingRequestCount === 0) {
    endLoading();
  }
}

// 默認超時設置
/* eslint-disable */

// axios.defaults.timeout = 60000 * 10
axios.defaults.timeout = 60000 * 2
// 相對路徑設置

// loading圖

// http request 攔截器
axios.interceptors.request.use(
  config => {

    if (!config.headers['Content-Type']) {
      config.headers = {

    // 判斷ie加時間戳防止不請求接口
    if (window.ActiveXObject || 'ActiveXObject' in window) {

    showFullScreenLoading()

    return config
