I want to update the progress bar according to the count of checkboxes checked. it should keep updating when checkboxes checked and unchecked. it's better to identify the progress bar using it's id.

Here is my Html code

<ul>
  <li><input type="checkbox" id="select_all"/> Selecct All</li>
  <li><input class="checkbox" type="checkbox">  Item 1</li>
  <li><input class="checkbox" type="checkbox">  Item 2</li>
  <li><input class="checkbox" type="checkbox">  Item 3</li>
  <li><input class="checkbox" type="checkbox">  Item 4</li>
  <li><input class="checkbox" type="checkbox">  Item 5</li>
  <li><input class="checkbox" type="checkbox">  Item 6</li>
</ul>
<div class="progress">
  <span class="progress-bar progress-bar-striped bg-success" id="CheckProgress" role="progressbar" style="width: 0%" aria-valuenow="25" aria-valuemin="0" aria-valuemax="100"></span>
</div>

Here is my javascript

$(document).ready(function () {
  var count = 0;
  var checked = 0;
  function countboxes() {
    count = $("input[type='checkbox']").length;
    console.log(count);
  }
  countboxes();
  $(":checkbox").click(countBoxes);
  function countChecked() {
    checked = $("input:checked").length;
    var percentage = parseInt(((checked / count) * 100));
    $(".CheckProgress").progress({
      value: percentage
    });
    $("#CheckProgress").css("width", percentage + "%");
  }
  countChecked();
  $(":checkbox").click(countChecked);
});

Firstly you've defined the function with a name of countboxes(), not countBoxes(), and JS is case-sensitive. Also there is no default progress() method in jQuery, nor is it in jQueryUI or Bootstrap. You don't need it either as all you do is set the width of the progress bar to the given percentage value.

To do this in the most simple way you simply need to use a change event handler and work out the percentage of checked boxes against the total. Then you can set the progress bar width to that. Try this:

$(document).ready(function() {
  var $checkboxes = $('.checkbox');
  var $progress = $('#CheckProgress');
  var total = $checkboxes.length;
  
  $checkboxes.on('change', function() {
    var checked = $checkboxes.filter(':checked').length;
    var progressWidth = (checked / total) * 100;
    $('.progress-bar').css('width', progressWidth + '%');
  });
});
.progress-bar { width: 0; }

Progress bar for counting checkboxes, Uses a bit of Javascript to count checkboxes with a JQuery UI progress bar </ p>. 8. </form>. 9. <div class="progressbar-container">. 10. Hello! I have a column of checkboxes, some checked some not. Using your formula I still get 0.0 as a result. However, when I use your formula across one row, the formula produces the correct result. I have of course altered the formulas to refer to the correct cells, but I just can't seem to sum checked boxes vertically.

Please see the below example for your solution.

jQuery('#btnTest').click(function(){
  var i = 0;
  var total_checkboxes = 0;
  var percent_checked;
  // Get all checkboxes with class name checkbox
  total_checkboxes = jQuery('#checbox_holder input[type="checkbox"].checkbox').length;
  //console.log(total_checkboxes);
  // Now iterate over each checkbox inside #checbox_holder div
  jQuery('#checbox_holder input[type="checkbox"]').each(function(){
    //Check if we have checkbox with class name checkbox
    if(jQuery(this).hasClass('checkbox')){
      // CHeck if checkbox is checked or not
      if(jQuery(this).prop("checked") == true){
        // Increment no of checked checboxes;
        i++;        
      }      
    }    
  });
  // Calculate percentage of checked checkboxs
  percent_checked = ( i / total_checkboxes ) * 100;
  //console.log(percent_checked);
  //console.log(i);
  //Assign width to the progress bar
  jQuery('#CheckProgress').css('width', percent_checked+'%');
});
.progress{
  width: 100%;
  border: 2px solid #ccc;
}
.progress-bar{
  display: block;
  background: green;
}
