javascript - Change background color on refresh with Vanilla JS -

-

There is a problem changing the background color when I refresh each one. Any help is appreciated that this is my JS yet: 

  var color = ['# 760c8', '# 4782b1', '# e889c']; Var change background = function () {document.body.style.background = colors ([Math.floor (Math.random (* * colors.length)]);}; Change background ();    
 
 
 You are almost there. In the line  
  document.body.style.background = colors ([Math.floor (Math.random (* * colors.length)];   
 You  [Math.flur (Math.Rendum (*) * Colors Length ).]  Otherwise you think that you want to call  colors  as a code. The index wants to use an array of what the square brackets do, so it should  
  document.body.style.background = colors [Math.floor (Math.random (* * colors.length) ];   
 and it will be alright.

I am trying to implement a screen-scraps application that opens a URL in which a parameter changes as it is for a loop: var data = [ '100', '101', '102', '103', '104']; (Var indexA = 0; indexA & lt; data.length; indexA ++) for {Phantom Generation ({'port': freeport}, function (pH) {ph.create page (function (page) {page.open ("http: //...++ data [index B] +" ...

Data is verified in scrap HTML and from index to array Matches. So in page 101 I scrap '101 and retrieve' and pu
