How to checked the checkbox if my checkbox is using html and javascript?

How can i checked the checkbox if the data is already in the database as selected by user ? For normal html, i can use checked , however, im using javascript for this one. is there any way to edit the html instead of the javascript ?

 <td><div align="center"><span class="formlist">
      <select id="plant" name="plant[]" class="form-control" multiple="multiple">
        <?php 
                    $query_plant = "SELECT * FROM plant WHERE plant_enable=1 ORDER BY plant_name";
                    $rs_plant = DB_Query($query_plant);

                    while ($row_plant = DB_FetchRow($rs_plant)) {

                        $plant.='<option value='.$row_plant["plant_id"].'>' .$row_plant["plant_name"].' ['.$row_plant["plant_id"].']</option>';

                        }   

                    mysql_free_result($rs_plant);
                    echo $plant;
                ?>
      </select>
    </span></div></td>

enter image description here

 <script type="text/javascript">
        $(function () {
            $('#plant').multiselect({
                includeSelectAllOption: true
            });
			 $('#btnSelected').click(function () {
                var selected = $("#plant option:selected");
                var message = "";
                selected.each(function () {
                    message += $(this).text() + " " + $(this).val() + "\n";
                });
                alert(message);
            });
            
               });
    </script>

1) First you can add selected attribute to options which is user already selected and stored in database . like this 

 $userPlants = [1,2,3,4];  //fetched value from database . previously user selected .

<option value="<?php echo $row_plant["plant_id"] ?>"

          <?php 

          if(in_array($row_plant["plant_id"], $userPlants)) 
           {
               echo " selected";
           } 

           ?>
><?php echo $row_plant["plant_name"] ?></option>


$(function () {
            $('#plant').multiselect({
                includeSelectAllOption: true
            });
            
	  // $("#plant").multiselect("refresh");  //if you need to refresh the multiselect use like this .

              });

You can create an array of all plants that user has already selected. And then do it like this

  <td><div align="center"><span class="formlist">
  <select id="plant" name="plant[]" class="form-control" multiple="multiple">
    <?php        
            // query to fetch user palnts and crate an array
            $userPlants = [1231,1281,1241,1271];                       


                $query_plant = "SELECT * FROM plant WHERE plant_enable=1 ORDER BY plant_name";
                $rs_plant = DB_Query($query_plant);

                while ($row_plant = DB_FetchRow($rs_plant)) {

                    $plant.='<option value='.$row_plant["plant_id"];

                    if (in_array($row_plant["plant_id"], $userPlants)) {
                        echo " checked ";
                    }

                    $plant.= '>' .$row_plant["plant_name"].' ['.$row_plant["plant_id"].']</option>';

                    }   

                mysql_free_result($rs_plant);
                echo $plant;
            ?>
  </select>
</span></div></td>
