我正在使用来自 jQuery Mobile 的自定义选择菜单，我想将图标放入自定义弹出菜单中以伴随每个option. 我将data-icon属性应用于 each option，如下所示：

<select name='mySelect' id='mySelect' data-icon='gear'>
    <option value='0' data-icon='star'>Option 0</option>
    <option value='1' data-icon='star'>Option 1</option>
    <option value='2' data-icon='star' selected="selected">Option 2</option>
</select>

FWIW，我已经验证了我的自定义图标可以在选择按钮本身中使用。我期望图标出现在自定义菜单中是完全错误的吗？

默认情况下不支持此功能，但这里有一段快速代码可以使其成为可能：

//wait for the correct page to initialize
$(document).delegate('#home', 'pageinit', function () {

    //loop through each of the SELECT elements in this page
    $.each($(this).find('select'), function () {

        //get the ID of this select because it's menu's ID is based off of it
        var currentID = this.id;

        //iterate through each of the OPTION elements for this SELECT element
        $.each($(this).find('option'), function (index, element) {

            //if the OPTION element has the `data-icon` attribute
            if ($(element).attr('data-icon') != undefined) {

                //update the menu for this SELECT by adding an icon SPAN element
                //to each of the OPTION elements that has a `data-icon` attribute
                $('#' + currentID + '-menu').children().eq(index).find('.ui-btn-inner').append('<span class="ui-icon ui-icon-' + $(element).attr('data-icon') + ' ui-icon-shadow" />');
            }
        });
    });
});​​
