How can I change wordpress shortcode value, using JavaScript

I am using Watupro plugin for simple test. In result window there are variables that display numeric test results: %%CATEGORY-POINTS-4%%, %%CATEGORY-POINTS-5%% etc.

I am using Progress Bar plugin, to display progress bar with results via shortcode. [wppb progress=%%CATEGORY-POINTS-4%%/130 option=green] gives me nice progress bar, based on student's results in each category.

However I want to display different colors of progress bar, depending on result. In order to achieve that, I want to change value of shortcode, based on numeric values.

I came up with this code so far:

HTML:

<div class="bar" data-score="%%CATEGORY-POINTS-4%%">[wppb progress=%%CATEGORY-POINTS-4%%/130 option=green]</div>

<div class="bar" data-score="%%CATEGORY-POINTS-5%%">[wppb progress=%%CATEGORY-POINTS-5%%/130 option=green]</div>

<script type="text/javascript">
results();
</script>

JavaScript:

function results() {
    var bar = document.getElementsByClass('bar');
    var score = bar.getAttribute('data-score');
    alert (score);
    if (score < 47) {
// ???
 }
    if (score > 46 && 4_score < 71) {
// ???
 }
    if (score > 70) {
// ???
 }

I guess I need to come up with code that changes shortcode attribute option to different color for each div respectively.

Any ideas?

Since you are using WP, you can try jQuery like this:

let score = jQuery('.bar').data('score'); // get element data-score
if (score > 46 && score < 71) { // your condition
$(".green").toggleClass('green yellow'); // changes class green to yellow
}

Then create new CSS class yellow:

div.wppb-progress > span.yellow {
background: linear-gradient(to bottom, #ffe893 0%,#ffd644 33%,#f5c001 62%,#bd9400 100%);
}

Ok. I got it solved. I added loop, so, Javascript goes through all divs.

Here's the code:

<div id="watupro_quiz" class="quiz-area single-page-quiz">
  <div id="startOutput">&nbsp;</div>

<!--<script type="text/javascript" src="https://psy-help.ee/wp-content/scripts/test_results.js"></script>-->

  <div class="bar" data-score="71" data-less="47" data-more="70">
    <div class="wppb-wrapper ">
      <div class="wppb-progress fixed"><span class="yellow" style="width: 39.230769230769%;"><span></span></span></div>
    </div>
  </div>
  <div class="bar" data-score="62">
    <div class="wppb-wrapper ">
      <div class="wppb-progress fixed"><span class="yellow" style="width: 47.692307692308%;"><span></span></span></div>
    </div>
  </div>

  <!--<script type="text/javascript">
    results();-->
  </script>

</div>

div.wppb-wrapper {
    clear: both;
}

div.wppb-progress {
    height: 25px;
    width: 400px;
    background: #555;
    -moz-border-radius: 30px;
    -o-border-radius: 30px;
    border-radius: 30px;
    position: relative;
}

div.wppb-progress > span.green {
    background: #83c783;
    background: -moz-linear-gradient(top, #83c783 0%, #52b152 33%, #008a00 62%, #005700 100%);
    background: -webkit-gradient(linear, left top, left bottom, color-stop(0%,#83c783), color-stop(33%,#52b152), color-stop(62%,#008a00), color-stop(100%,#005700));
    background: -webkit-linear-gradient(top, #83c783 0%,#52b152 33%,#008a00 62%,#005700 100%);
    background: -o-linear-gradient(top, #83c783 0%,#52b152 33%,#008a00 62%,#005700 100%);
    background: -ms-linear-gradient(top, #83c783 0%,#52b152 33%,#008a00 62%,#005700 100%);
    background: linear-gradient(to bottom, #83c783 0%,#52b152 33%,#008a00 62%,#005700 100%);
}

div.wppb-progress > span {
    display: block;
    height: 25px;
    -moz-border-radius: 30px;
    -o-border-radius: 30px;
    border-radius: 30px;
    background: #5a84c4;
    background: -moz-linear-gradient(top, #5a84c4 0%, #1a2275 100%);
    background: -webkit-gradient(linear, left top, left bottom, color-stop(0%,#5a84c4), color-stop(100%,#1a2275));
    background: -webkit-linear-gradient(top, #5a84c4 0%,#1a2275 100%);
    background: -o-linear-gradient(top, #5a84c4 0%,#1a2275 100%);
    background: -ms-linear-gradient(top, #5a84c4 0%,#1a2275 100%);
    background: linear-gradient(top, #5a84c4 0%,#1a2275 100%);
    -webkit-box-shadow: inset 0 2px 9px rgb(255 255 255 / 30%), inset 0 -2px 6px rgb(0 0 0 / 40%);
    -moz-box-shadow: inset 0 2px 9px rgba(255,255,255,0.3), inset 0 -2px 6px rgba(0,0,0,0.4);
    box-shadow: inset 0 2px 9px rgb(255 255 255 / 30%), inset 0 -2px 6px rgb(0 0 0 / 40%);
    overflow: hidden;
    position: relative;
}

let barElement = document.getElementsByClassName("bar");
for (let i = 0; i < barElement.length; i++) {
  let wrapper = barElement[i].firstElementChild;
  let bar = wrapper.firstElementChild;
  let span = bar.firstElementChild;
  let score = barElement[i].getAttribute("data-score");
  let low = barElement[i].getAttribute("data-less");
  let high = barElement[i].getAttribute("data-more");
  if (score < low) {
    span.classList.remove("yellow");
    span.classList.add("green");
  } if (score > high) {
    span.classList.remove("yellow");
    span.classList.add("red");
  }
}
