🧩 Front-End Code Integration (JS)

Add the following code snippet into your <project>_core.js file to pull live weight into a specific field:

function {modulename}_add_afterload(){
   let machineid = 1;  // Change machine ID as needed
   let field = 'weight';  // Change to actual field name where weight will be displayed

   if (branchcode == 'PM3'){
      machineid = 2;
   }

   $(`#${field}`).data('tool','ok');
   $(`#${field}`).after(`<div class="inptool" data-id="weightapi" onclick="getWeightFromApi(${machineid},'${field}');">
                           <i class="fa-duotone fa-solid fa-dumbbell" style="font-size:12pt;"></i>
                       </div>`);
}
