英文:
nodeMCU and ajax instead of refresh one element repeats whole web-page
问题
I need help with reloading two elements at my webpage. I have small electronics and its brain is NodeMCU. I need there two outputs (which are connected to relays) and two inputs.
With inputs I want to update periodically (without manual reloading the webpage) two elements of the page according to two digital inputs. For that, I use ajax. I have found some hints: http://www.martyncurrey.com/esp8266-and-the-arduino-ide-part-8-auto-update-webpage/
Almost everything works perfectly (outputs and inputs). Only one problem is that after a timeout, the whole webpage is repeated and is shown twice in the web browser.
Sorry for adding my code as an image (below). But when I insert it here as text, many parts of the code are recognized as HTML tags and are not shown.
I have placed this code on my webpage: http://fiksoftware.4fan.cz/bojler.ino
Could anybody please give me any advice on what is wrong with my code (below).
Thanks a lot to all.

问题出在我在请求数据后发送整个页面。
