使用jQuery从JavaScript对象向选择添加选项的最佳方法是什么？

#1 楼

$.each(selectValues, function(key, value) {   
     $('#mySelect')
         .append($("<option></option>")
                    .attr("value", key)
                    .text(value)); 
});

#2 楼

var output = [];

$.each(selectValues, function(key, value)
{
  output.push('<option value="'+ key +'">'+ value +'</option>');
});

$('#mySelect').html(output.join(''));

#3 楼

 var selectValues = {
  "1": "test 1",
  "2": "test 2"
};
var $mySelect = $('#mySelect');
//
$.each(selectValues, function(key, value) {
  var $option = $("<option/>", {
    value: key,
    text: value
  });
  $mySelect.append($option);
}); 

 <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<select id="mySelect"></select> 

#4 楼

var list = $("#selectList");
$.each(items, function(index, item) {
  list.append(new Option(item.text, item.value));
});

var list = document.getElementById("selectList");
for(var i in items) {
  list.add(new Option(items[i].text, items[i].value));
}

#5 楼

$(new Option('myText', 'val')).appendTo('#mySelect');

#6 楼

$.each(selectData, function(i, option)
{
    $("<option/>").val(option.id).text(option.title).appendTo("#selectBox");
});

#7 楼

$("#mySelect").append(
  $.map(selectValues, function(v,k){

    return $("<option>").val(k).text(v);
  })
);

$("#mySelect").append(
  $.map(selectValues, (v,k) => $("<option>").val(k).text(v))
  // $.map(selectValues, (v,k) => new Option(v, k)) // using plain JS
);

#8 楼

var options = $('#mySelect').get(0).options;
$.each(selectValues, function(key, value) {
        options[options.length] = new Option(value, key);
});

#9 楼

var options;
$.each(data, function(index, object) {

 var output = [];
 var length = data.length;
 for(var i = 0; i < length; i++)
