javascript - Using PHP inside jQuery and if/else statements -


i have 5 circles appear inside div change depending on accuracy of thing.

for example <20 accuracy 1 filled (red) circle, 4 unfilled circles.

visual: 60-80 accuracy http://puu.sh/hnjsr/20af976827.png

the below code inside:

$(document).ready(function(){

the code:

var accuracy1 = <?php echo 100*(1-$s1/1.33333); ?>; var accuracy2 = <?php echo 100*(1-$s2/1.33333); ?>;  if (accuracy1 < 20) {         $('<div class="accuracycircle accuracycircle1"></div>').appendto('#circlesdiv1');         $('<div class="accuracycircle accuracycircleunfilled"></div>').appendto('#circlesdiv1');         $('<div class="accuracycircle accuracycircleunfilled"></div>').appendto('#circlesdiv1');         $('<div class="accuracycircle accuracycircleunfilled"></div>').appendto('#circlesdiv1');         $('<div class="accuracycircle accuracycircleunfilled"></div>').appendto('#circlesdiv1'); } elseif(accuracy1 >= 20 && accuracy1 < 40) {         $('<div class="accuracycircle accuracycircle2"></div>').appendto('#circlesdiv1');         $('<div class="accuracycircle accuracycircle2"></div>').appendto('#circlesdiv1');         $('<div class="accuracycircle accuracycircleunfilled"></div>').appendto('#circlesdiv1');         $('<div class="accuracycircle accuracycircleunfilled"></div>').appendto('#circlesdiv1');         $('<div class="accuracycircle accuracycircleunfilled"></div>').appendto('#circlesdiv1'); } elseif(accuracy1 >= 40 && accuracy1 < 60) {         $('<div class="accuracycircle accuracycircle3"></div>').appendto('#circlesdiv1');         $('<div class="accuracycircle accuracycircle3"></div>').appendto('#circlesdiv1');         $('<div class="accuracycircle accuracycircle3"></div>').appendto('#circlesdiv1');         $('<div class="accuracycircle accuracycircleunfilled"></div>').appendto('#circlesdiv1');         $('<div class="accuracycircle accuracycircleunfilled"></div>').appendto('#circlesdiv1'); } elseif(accuracy1 >= 60 && accuracy1 < 80) {         $('<div class="accuracycircle accuracycircle4"></div>').appendto('#circlesdiv1');         $('<div class="accuracycircle accuracycircle4"></div>').appendto('#circlesdiv1');         $('<div class="accuracycircle accuracycircle4"></div>').appendto('#circlesdiv1');         $('<div class="accuracycircle accuracycircle4"></div>').appendto('#circlesdiv1');         $('<div class="accuracycircle accuracycircleunfilled"></div>').appendto('#circlesdiv1'); } else {         $('<div class="accuracycircle accuracycircle5"></div>').appendto('#circlesdiv1');         $('<div class="accuracycircle accuracycircle5"></div>').appendto('#circlesdiv1');         $('<div class="accuracycircle accuracycircle5"></div>').appendto('#circlesdiv1');         $('<div class="accuracycircle accuracycircle5"></div>').appendto('#circlesdiv1');         $('<div class="accuracycircle accuracycircle5"></div>').appendto('#circlesdiv1'); }

$s1 , $s2 numbers declared earlier in php tag transform make accuracy between 0 , 100.

it doesn't work , messy. doing wrong , how clean too?

here how can clean code.

  1. use repeater repeat string, instead of repeating code
  2. use :lt selector select elements having index less provided

demo

// repeat string num times  string.prototype.repeat = function(num) {    return new array(num + 1).join(this);  };    var accuracy1 = 70; // dynamic    var totalcircles = 5,    nooffilledcircles = math.ceil(accuracy1 / 20);  nooffilledcircles = nooffilledcircles > 5 ? 5 : nooffilledcircles;    var circlehtml = '<div class="accuracycircle"></div>';    $('#circlesdiv1').append(circlehtml.repeat(totalcircles)).find('div:lt(' + nooffilledcircles + ')').addclass('accuracycircle1');
div#circlesdiv1 {    height: 30px;    width: 200px;    background-color: #3c3e46;  }  #circlesdiv1 .accuracycircle {    background-color: #8a8a8a;    display: inline-block;    width: 15px;    height: 15px;    border-radius: 50%;    margin: 5px;  }  div.accuracycircle1 {    background-color: #dbff94 !important;  }
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"></script>  <div id="circlesdiv1"></div>
