今天我們要來分享一款很實用的jQuery插件，它是一個基于jQuery多級聯(lián)動的省市地區(qū)Select下拉框，并且值得一提的是，這款聯(lián)動下拉框是經(jīng)過自定義美化過的，外觀比瀏覽器自帶的要漂亮許多。另外，這個Select下拉框也可以綁定下拉事件，并獲取當前選中項的值。
    html代碼：

    $(this).find('ul').show();
    e.stopPropagation();
    });
    $('[name="nice-select"] li').hover(function (e) {
    $(this).toggleClass('on');
    e.stopPropagation();
    });
    $('[name="nice-select"] li').click(function (e) {
    var val = $(this).text();
    var dataVal = $(this).attr("data-value");
    $(this).parents('[name="nice-select"]').find('input').val(val);
    $('[name="nice-select"] ul').hide();
    e.stopPropagation();
    alert("中文值是：" + val);
    alert("數(shù)字值是：" + dataVal);
    //alert($(this).parents('[name="nice-select"]').find('input').val());
    });
    $(document).click(function () {
    $('[name="nice-select"] ul').hide();
    });
    </script>
