插件jquery.cityselect.js省市联动效果怎么使用

HTML

首先在head中载入jquery库和cityselect插件。

script type="text/javascript" src="js/jquery.js"/script

script type="text/javascript" src="js/jquery.cityselect.js"/script

接下来，我们在#city中，放置三个select，并且三个select分别设置class属性为：prov、city、dist，分别表示省、市、区（县）三个下拉框。注意如果只想实现省市二级联动，则去掉第三个dist的select即可。

div id="city"

select class="prov"/select

select class="city" disabled="disabled"/select

select class="dist" disabled="disabled"/select

/div

jQuery

调用cityselect插件非常简单，直接调用：

$("#city").citySelect();

自定义参数调用，设置默认省市区。自定义参数调用，设置默认省市区。

$("#city").citySelect({

url:"js/city.min.js",

prov:"湖南", //省份

city:"长沙", //城市

dist:"岳麓区", //区县

nodata:"none" //当子集无数据时，隐藏select

});

当然，你还可以扩展，自定义下拉列表选项数据，你可以根据需要设置下拉内容，注意数据格式一定要为JSON格式。

$("#city").citySelect({

url:{"citylist":[

{"p":"前端技术","c":[{"n":"HTML"},{"n":"CSS","a":[{"s":"CSS2.0"},{"s":"CSS3.0"}]},

{"n":"JAVASCIPT"}]},

{"p":"编程语言","c":[{"n":"C"},{"n":"C++"},{"n":"PHP"},{"n":"JAVA"}]},

{"p":"数据库","c":[{"n":"Mysql"},{"n":"SqlServer"},{"n":"Oracle"}]},

]},

prov:"",

city:"",

dist:"",

nodata:"none"

});

你还可以利用PHP等后台语言将数据库中的数据转换成JSON格式，然后使用url参数指向后台地址也能实现无刷新联动效果。

$("#city").citySelect({

url:"data.php"

});

web前端怎么引用jquery省市级联插件

1. [代码]新增选择城市    

$(function(){

$("#province").cityCasCade("#city").cityCasCade('select','河南省');

//or

$("#province").cityCasCade("#city").cityCasCade('select','河南省','开封市');

}

/**

* java diqye

* 城市数据时从网上Copy的

* 级联功能也是参考网上已做好的思路

* 封装成插件为了以后使用方便

* add 增加选中城市方法select

jquery弹出层，类似选择城市，当我选择一个城市以后，这个层关闭且这个城市的值保留

这不简单嘛！ jquery弹出层后，选择什么城市--》用JS记录下选择的城市的信息，比如，城市名、城市ID之类的--隐藏弹出层。 然后想在哪里显示这个层，就可以用jquery显示用JS记录下的城市信息。这时就可以随便在哪显示了啊！

怎么用jquery实现城市

光凭jquery是定位不到城市的，定位城市是要通过ip来定位的。如果你想做到定位城市，意见如下：

去看看百度地图，调用百度地图api定位城市

自己用java 或者php写一个程序，来实现城市定位，然后在页面jquery显示出来

也可以用插件，在jquery调用
