Copy Selected Multiple Values To The Textbox From More Than One Drop Down March 27, 2024 Post a Comment I have tow drop downs as below. First Name Solution 1: If you accepting duplicate values then, this is the solution: I updated your HTML code to suit your needs by adding real values to your dropdown lists instead of using "FirstName,LastName". <!DOCTYPE html> <html> <head> <title></title> </head> <body> <select id="checkOwner" multiple="multiple" onchange="copyValue()"> <option value="John">John</option> <option value="Abeer">Abeer</option> </select> <br> <select id="checkMember" multiple="multiple" onchange="copyValue2()"> <option value="Doe">Doe</option> <option value="Trump">Trump</option> <option value="Abeer">Abeer</option> </select> <br> <input type="text" name="mytextbox" id="mytextbox" size="200"> </body> <script type="text/javascript"> function getOld(currentSelect) { var x = []; for (var option of document.getElementById(currentSelect).options) { if (option.selected) { x.push(option.value); } } return x; } function copyValue() { x = getOld('checkMember'); y = []; for (var option of document.getElementById('checkOwner').options) { if (option.selected) { y.push(option.value); } else { y = y.filter(value => value != option.value ); } } x = x.concat(y); document.getElementById('mytextbox').value = x.join(' '); } function copyValue2() { x = getOld('checkOwner'); y = []; for (var option of document.getElementById('checkMember').options) { if (option.selected) { y.push(option.value); } else { y = y.filter(value => value != option.value ); } } x = x.concat(y); document.getElementById('mytextbox').value = x.join(' '); } </script> </html> Copy Share Post a Comment for "Copy Selected Multiple Values To The Textbox From More Than One Drop Down" Top Question Activating Onbeforeunload Only When Field Values Have Changed What I'm trying to achieve is to Warn the user of unsav… Onpropertychange For A Textbox In Firefox?
