我有一个选定的下拉列表.我更改了选项内容并调用了所选择的触发器:更新但选择了不重建下拉列表.这是我的更新

<select name="shortcode" style="width: 150px; display: none;" class="chosen_select chzn-done" id="select_shortcode">
   <option value=""></option> 
   <option value="7183">7183</option>
   <option value="7983">7983</option>
</select>

这是选择下拉(它应该重建并最后删除两个<li>)

<ul class="chzn-results">
   <li id="select_shortcode_chzn_o_1" class="active-result" style="">7183</li>
   <li id="select_shortcode_chzn_o_2" class="active-result" style="">7983</li>
   <li id="select_shortcode_chzn_o_3" class="active-result" style="">8208</li>
   <li id="select_shortcode_chzn_o_4" class="active-result" style="">8308</li>
</ul>

这是我的jQuery代码:

$('#select_shortcode_mask').change(function(){
    var shortcode_mask = $('#select_shortcode_mask').val();
    $('#select_shortcode').empty();
    var shortcode = {"7X83":["7183","7983"],"8x08":["8208","8308"]};
    $('#select_shortcode').append("<option value=''></option>");
    if(jQuery.isArray(shortcode[shortcode_mask])){
            $.each( shortcode[shortcode_mask], function( subkey, subvalue ) {
                $('#select_shortcode').append("<option value='"+subvalue+"'>"+subvalue+"</option>");
            })
    } else {
        var full_shortcode = ["7183","7983","8208","8308"];
        if(jQuery.isArray(full_shortcode)){
            $.each(full_shortcode, function( subkey, subvalue ) {
                $('#select_shortcode').append("<option value='"+subvalue+"'>"+subvalue+"</option>");
            }) …
