這篇文章主要介紹了使用html5代碼來獲取地理位置，具體實(shí)現(xiàn)代碼如下并附有截圖,需要的朋友可以參考下

代碼如下:

/**

* 以下為html5代碼,獲取地理位置

*/

function getLocation() {

//檢查瀏覽器是否支持地理位置獲取

if (navigator.geolocation) {

//若支持地理位置獲取,成功調(diào)用showPosition(),失敗調(diào)用showError

// alert("正在努力獲取位置...");

var config = { enableHighAccuracy: true, timeout: 5000, maximumAge: 30000 };

navigator.geolocation.getCurrentPosition(showPosition, showError, config);

} else {

//alert("Geolocation is not supported by this browser.");

alert("定位失敗,用戶已禁用位置獲取權(quán)限");

}

}

/**

* 獲取地址位置成功

*/

function showPosition(position) {

//獲得經(jīng)度緯度

var x = position.coords.latitude;

var y = position.coords.longitude;

//配置Baidu Geocoding API

var url = "http://api.map.baidu.com/geocoder/v2/?ak=C93b5178d7a8ebdb830b9b557abce78b" +

"&callback=renderReverse" +

"&location=" + x + "," + y +

"&output=json" +

"&pois=0";

$.ajax({

type: "GET",

dataType: "jsonp",

url: url,

success: function (json) {

if (json == null || typeof (json) == "undefined") {

return;

}

if (json.status != "0") {

return;

}

setAddress(json.result.addressComponent);

},

error: function (XMLHttpRequest, textStatus, errorThrown) {

alert("[x:" + x + ",y:" + y + "]地址位置獲取失敗,請(qǐng)手動(dòng)選擇地址");

}

});

}

/**

* 獲取地址位置失敗[暫不處理]

*/

function showError(error) {

switch (error.code) {

case error.PERMISSION_DENIED:

alert("定位失敗,用戶拒絕請(qǐng)求地理定位");

//x.innerHTML = "User denied the request for Geolocation.[用戶拒絕請(qǐng)求地理定位]"

break;

case error.POSITION_UNAVAILABLE:

alert("定位失敗,位置信息是不可用");

//x.innerHTML = "Location information is unavailable.[位置信息是不可用]"

break;

case error.TIMEOUT:

alert("定位失敗,請(qǐng)求獲取用戶位置超時(shí)");

//x.innerHTML = "The request to get user location timed out.[請(qǐng)求獲取用戶位置超時(shí)]"

break;

case error.UNKNOWN_ERROR:

alert("定位失敗,定位系統(tǒng)失效");

//x.innerHTML = "An unknown error occurred.[未知錯(cuò)誤]"

break;

}

}

/**

* 設(shè)置地址

*/

function setAddress(json) {

var position = document.getElementById("txtPosition");

//省

var province = json.province;

//市

var city = json.city;

//區(qū)

var district = json.district;

province = province.replace('市', '');

position.value = province + "," + city + "," + district;

position.style.color = 'black';

}
