Question

我的select2具有这种动态形式。该表单允许我添加和删除表单输入，该表单大部分都可以工作，但是当我添加另一行表单输入时，先前的select2表单输入会更改其格式。我如何确保表单保持select2选择框的格式？

var room = 1;
function education_fields() {
 
    room++;
    var objTo = document.getElementById('education_fields')
    var divtest = document.createElement("div");
  divtest.setAttribute("class", "form-group removeclass"+room);
  var rdiv = 'removeclass'+room;
    divtest.innerHTML = '<div class="col-sm-3 nopadding"><div class="form-group"> <input type="text" class="form-control" id="Schoolname" name="Schoolname[]" value="" placeholder="School name"></div></div><div class="col-sm-3 nopadding"><div class="form-group"> <input type="text" class="form-control" id="Major" name="Major[]" value="" placeholder="Major"></div></div><div class="col-sm-3 nopadding"><div class="form-group"> <input type="text" class="form-control" id="Degree" name="Degree[]" value="" placeholder="Degree"></div></div><div class="col-sm-3 nopadding"><div class="form-group"><div class="input-group"> <select multiple="multiple" class="form-control" id="educationDate" name="educationDate[]"><option value="">Date</option><option value="2015">2015</option><option value="2016">2016</option><option value="2017">2017</option><option value="2018">2018</option> </select><div class="input-group-btn"> <button class="btn btn-danger" type="button" onclick="remove_education_fields('+ room +');"> <span class="glyphicon glyphicon-minus" aria-hidden="true"></span> </button></div></div></div></div><div class="clear"></div>';
    
    objTo.appendChild(divtest)
}
   function remove_education_fields(rid) {
     $('.removeclass'+rid).remove();
   }

</script>
