The page.waitForNavigation({waituntil:'networkidle2'}) would be waiting until time out if network has already been idled before invoke it.

For examle: await page.goto("https://www.aqistudy.cn/html/city_realtime.html?v=2.3", { waitUntil: "networkidle2" }); await page.type("#city", cities[i]); await page.tap("a#btnSearch"); await page.waitForNavigation({ waitUntil: "networkidle2" }); After the #btnSearch is tapped, the web uses javascript to access data to render the table. I thought using waitForNavigation could get the right result. However, the page would always be waiting until time out. It doesn’t work as I expected. How could I fix it?

Not sure about your specific code and whether your click is “happening” on the right element to trigger navigation, but in general if you want to make sure you catch an expected navigation event, create the waitForNavigation promise (but do not await it yet) BEFORE you trigger the navigation, i.e. before the click, not after. And then “await” that created promise, otherwise sometimes it will have happened so fast you will miss it.

So something like:

navresponse = page.waitForNavigation(['networkidle0', 'load', 'domcontentloaded']);
page.click('a#btnSearch');
await navresponse;

调接口抓数据吧

var method = 'GETDATA';
var object = {};

function getServerData(method, object, callback, period) {
  const key = hex_md5(method + JSON.stringify(object));
  const data = getDataFromLocalStorage(key, period);
  if (!data) {
    var param = getParam(method, object);
    $.ajax({
      url: '../apinew/aqistudyapi.php',
      data: {
        d: param
      },
      type: "post",
      success: function(data) {
        data = decodeData(data);
        obj = JSON.parse(data);
        if (obj.success) {
          if (period > 0) {
            obj.result.time = new Date().getTime();
            localStorageUtil.save(key, obj.result)
          }
          callback(obj.result)
        } else {
          console.log(obj.errcode, obj.errmsg)
        }
      }
    })
  } else {
    callback(data)
  }
}
