Two ways to realize automatic jump after n seconds in JS _javascript skill

The example of this article for everyone to share the JS implementation of the N-second automatic jump two methods for your reference, the specific contents are as follows

The first use of setinterval:

$ (function () {

      setinterval (changetime, 1000);

    });

    function Changetime () {

      var time;

      Time = $ ("#time"). Text ();

      Time = parseint (time);

      time--;

      if (time <= 0) {

        window.location.href = '/home/index ';

      } else {

        $ (' #time '). Text (time);

      }

    

The second use of settimeout:

$ (function () {

      settimeout (changetime, 1000);

    });

    function Changetime () {

      var time;

      Time = $ ("#time"). Text ();    

      Time = parseint (time);

      time--;

      if (time <= 0) {

        window.location.href = '/home/index ';

      } else {

        $ (' #time '). Text (time);

        SetTimeout (changetime, 1000);

      }

<div> you visit the page is abnormal, <span id= "time" >5</span> seconds automatically jump to home </div>

The above is the entire content of this article, I hope to learn JavaScript program to help you.
