首先，您的 HTML 无效。你无法发明自己的属性。如果您想使用元素存储自定义数据，请使用data-*，如下所示：

\n\n

<option data-city-en="Aytos" value="1">\xd0\xb3\xd1\x80. \xd0\x90\xd0\xb9\xd1\x82\xd0\xbe\xd1\x81</option>\n

\n\n

从那里你可以修改你的排序逻辑来阅读data属性：

\n\n

$("#shipping-city-select option[data-city-en]").sort(function(a, b) {\n    var at = $(a).data(\'city-en\');\n    var bt = $(b).data(\'city-en\');    \n    return at > bt ? 1 : (at < bt) ? -1 : 0;\n}).appendTo("#shipping-city-select");  \n

\n\n

请注意，您不需要detach()前面的元素append()正确的顺序排列

\n\n

另请注意，如果使用，您可以直接对包含西里尔字符的文本进行排序localeCompare()：

\n\n

$("#shipping-city-select option[data-city-en]").sort(function(a, b) {\n    return $(a).text().localeCompare($(b).text());\n}).appendTo("#shipping-city-select"); \n
