不用php怎麽調用微信jssdk

使用姿勢

^ajax(Common.ServerUrl?+?"GetWX.php",?{

data:?{

Type:?"config",

url:?location.href.split('#')[0]

},

dataType:?'json',

type:?'get',

timeout:?5000,

success:?function(data)?{

wx.config({

debug:?true,?//?開啟調試模式,調用的所有api的返回值會在客戶端alert出來，若要查看傳入的參數，可以在pc端打開，參數信息會通過log打出，僅在pc端時才會打印。

appId:?'……',?//?必填，公眾號的唯壹標識

timestamp:?data.timestamp,?//?必填，生成簽名的時間戳

nonceStr:?data.nonceStr,?//?必填，生成簽名的隨機串

signature:?data.signature,?//?必填，簽名，見附錄1

jsApiList:?["getLocation"]?//?必填，需要使用的JS接口列表，所有JS接口列表見附錄2

});

}

})

wx.ready(function()?{

wx.getLocation({

type:?'wgs84',?//?默認為wgs84的gps坐標，如果要返回直接給openLocation用的火星坐標，可傳入'gcj02'

success:?function(res)?{

var?latitude?=?res.latitude;?//?緯度，浮點數，範圍為90?~?-90

var?longitude?=?res.longitude;?//?經度，浮點數，範圍為180?~?-180。

plus2.storage.setItem("latitude",?latitude);

plus2.storage.setItem("longitude",?longitude);

}

});

});
