Call function with setInterval in jQuery

Question

I m trying to create a interval call to a function in jQuery  but it doesn t work  My first question is  can I mix common JavaScript with jQuery    Should I use setInterval  test    1000   or something like this   var refreshId   setInterval function        code       5000     Where do I put the function that I call and how do I activate the interval  Is it a difference in how to declare a function in JavaScript compared to jQuery

To write the best code  you  should  use the latter approach  with a function reference   var refreshId   setInterval function       5000     or  function test      var refreshId   setInterval test  5000     but your approach of   function test      var refreshId   setInterval  test     5000     is basically valid  too  as long as test   is global    Note that there is no such thing really as  in jQuery   You re still writing the Javascript language  you re just using some pre-made functions that are the jQuery library

jQuery is just a set of helpers libraries written in Javascript  You can still use all Javascript features  so you can call whatever functions  also from inside jQuery callbacks  So both possibilities should be okay

First of all  Yes you can mix jQuery with common JS       Best way to build up an intervall call of a function is to use setTimeout methode     For example  if you have a function called test   and want to repeat it all 5 seconds  you could build it up like this     function test        console log  test called        setTimeout test  5000       Finally you have to trigger the function once     document  ready function        test          This document ready function is called automatically  after all html is loaded
