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：

代碼如下:

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();
