javascript - add new select option with an attribute -


i want add href attribute select list (countrylist) elements:

var s = document.getelementbyid('countrylist');  var option = document.createelement("option"); option.text = "fr"; option.value = "fr"; option.setattribute('href', 'https://www.facebook.com/'); s.add(option);  var option2 = document.createelement("option"); option2.text = "en"; option2.value = "us"; option2.setattribute('href', 'https://www.facebook.com/'); s.add(option2);  var option3 = document.createelement("option"); option3.text = "ar"; option3.value = "ar"; option3.setattribute('href', 'https://www.google.com/'); s.add(option3);  var option4 = document.createelement("option"); option4.text = "es"; option4.value = "es"; option4.setattribute('href', 'https://www.yahoo.com/'); s.add(option4);  var option5 = document.createelement("option"); option5.text = "it"; option5.value = "it"; option5.setattribute('href', 'https://www.youtube.com/'); s.add(option5);

when select option should redirect me specific href address, redirects me "yahoo" , "youtube", while other elements don't redirect.

try 

    var s = document.getelementbyid('countrylist');      var option = document.createelement("option");      option.text = "fr";      option.value = "fr";      option.setattribute('data-href','https://www.facebook.com/') ;      s.add(option);         var option2 = document.createelement("option");       option2.text = "en";       option2.value = "us";       option2.setattribute('data-href','https://www.facebook.com/') ;         s.add(option2);       var option3 = document.createelement("option");       option3.text = "ar";       option3.value = "ar";       option3.setattribute('data-href','https://www.google.com/') ;         s.add(option3);       var option4 = document.createelement("option");       option4.text = "es";       option4.value = "es";       option4.setattribute('data-href','https://www.yahoo.com/') ;         s.add(option4);       var option5 = document.createelement("option");       option5.text = "it";       option5.value = "it";       option5.setattribute('data-href','https://www.youtube.com/') ;         s.add(option5);              function redirect(obj){       window.open(obj.selectedoptions[0].getattribute("data-href"))                 }
<select id="countrylist" onchange="redirect(this);">  <option>select country</option>  </select>
