javascript - how to set timeout each time a function is called -


i'm trying create if statement sets timeout when function called:

    var timeoutid;      if (//function1 called) {       timeoutid = settimeout(function1, 30000);     } 

the idea function gets repeatedly called after 30 seconds, timeout can reset @ point if function called (e.g. button clicked). how can accomplished? many thanks.

instead of settimeout use setinterval. call callback function repeatedly every given time , can clear via clearinterval function.

see example

const start = document.getelementbyid('start');  const clear = document.getelementbyid('clear');    let intervalid = '';    start.addeventlistener('click', () => intervalid = setinterval(() => console.log('tick'), 1000));    clear.addeventlistener('click', () => clearinterval(intervalid));
<button id="start">start</button>  <button id="clear">clear</button>
