jQuery dynamic background image effect implementation method_jquery

The example in this article describes how to implement the jQuery dynamic background image effect. Share it with everyone for your reference. The details are as follows:

Put the background images into the directory according to 1.jpg - 20.jpg. jQuery will randomly call these images as the background

$(document).ready(function(){
  bgImageTotal=20;
  randomNumber = Math.round(Math.random()*(bgImageTotal-1))+1;
  imgPath=('/my/image/path/'+randomNumber+'.jpg');
  $('h1').css('background-image', ('url("'+imgPath+'")'));
});

I hope this article will be helpful to everyone’s jquery programming design.
