How to implement page content update without reloading it?

Question

PHP

There is a RasPi, 18b20 are connected to it via 1-w, collecting the temperature in all rooms. Lamp is installed, the php page collects data from all sensors, but it itself is static. How can I make sure that the information on the page is updated without reloading it (like the temperature on the mail.ru main page or notifications about letters)?

Answer 1

Add an AJAX request to the page, which will asynchronously send a request to the web server on a timer (for example, a php function that collects data from sensors and returns them, say, in JSON format). After the data is received, your method is triggered, written in javascript for such a case, which changes the values ​​in the displayed html code.
Of course, the easiest way is to make an AJAX request based on JQuery $.ajax, but for your task it is quite possible to insert a block of code in pure javascript that sends a request and processes the data received in response.

Why are you interested in it without a reboot? You can solve it more simply: add a meta refresh tag to auto-refresh the page after a certain time interval (in seconds).
Well, if you really need it without reloading the page, you can use AngularJS , which is well suited for one-page sites. There are methods for working with ajax .
