Puppeteer page.click(selector) not responding for IFrames

Question

 await page.evaluate(() => { window.scrollBy(0, window.innerHeight); }) jest.setTimeout(20000) await page.click('#ApplyBthNAP, #btnCheck'); 

 <iframe id="frameContent" frameborder="0" height="100%" marginheight="0" marginwidth="0" scrolling="no" width="100%" src="html/status/wlaninfo.asp" style="height: 585px;"></iframe> <div id="ApplyBthNAP"> <span class="tabal_head"> <script> document.write(status_wlaninfo_language['amp_napinfo_title']); </script> Neighboring AP Information </span> <input style="margin-left:25px;" name="btnCheck" class="submit" id="btnCheck" type="button" value="Query"> <script> document.getElementsByName('btnCheck')[1].value = status_wlaninfo_language['amp_stainfo_query']; </script> </div> 

The error i keep getting is FAIL test\\header.test.js (24.613s) × Click and check url (23238ms)

● Click and check url

TypeError: Cannot read property 'click' of null

  at Page.click (node_modules/puppeteer/lib/Page.js:816:18)

console.assert node_modules\\puppeteer\\lib\\Page.js:815 AssertionError [ERR_ASSERTION]: No node found for selector: #ApplyBthNAP, #btnCheck

Test Suites: 1 failed, 1 total

After a few research i got to know that puppeteer has some bug associated with IFrames. Requirement is to press a button with Value='Query' The only problem with normal selector method it is showing null. Please enlighten me. Thanks in advance

Answer 1

也许您是说('#ApplyBthNAP #btnCheck')而不是('#ApplyBthNAP, #btnCheck') 在 div中查找按钮，而不是按钮和 div？
