js实现城市地名的选择时多音怎么判断

js实现城市地名的选择时多音怎么判断

1. 首先写一个js文件，areaLocation.js:

var provinceArray= new Array()

provinceArray=[

{"pname":"江苏",

"country":[

{ "cname":"南京市",

"town":["玄武区","白下区","秦淮区","建邺区","雨花台","江宁区", "六合区","溧水县","高淳县"]},

{ "cname":"南通市",

"town":["崇川区","港闸区","启东市","如皋市","通州市","海门市","海安县","如东县"] },

{ "cname":"苏州市",

"town":["金阊区","沧浪区","平江区","虎丘区","吴中区","张家港","昆山市","吴江市","太仓市"] }

]

},

{"pname":"上海",

"country":[

{ "cname":"上海市",

"town":["徐汇区","普陀区","杨浦区","虹口区","卢湾区","浦东区","黄浦区","长宁区","闸北区","静安区","闵行区","松江区"]

}

]

}

]

如果只是写浏览器端js的话，需要一个庞大的js问价的ip数据库

// 数据库

var database = {

'123.123.123.123': {

province: '北京市',

city: '北京市',

operators: '联通',

},

'123.123.123.124': {

province: '北京市',

city: '北京市',

operators: '联通',

}

// ...

}

// 主函数

var inquireIP = function (ip) {

if(database[ip]) {

return database[ip]

}else{

console.log('找不到ip：' + ip)

return null

}

}

// 调用

var ipData = inquireIP('123.123.123.123')

这样子这个js文件会很大，也可以调用API的形式，为方便下面js代码使用了jquery

// 主函数

var inquireIP = function (ip, callback) {

$.ajax({

url: '你的API接口地址',

type: 'GET',

dataType: 'jsonp',

data: {ip: ip}

})

.done(function(data) {

callback(data)

})

}

// 调用

inquireIP('123.123.123.123', function (data) {

console.log(data)

})

这样子就可以在服务端处理，当然提前你得有服务器，并搭建一个查询ip的API接口
