温度を摂氏から華氏に変更しようとしていますが、それを一度だけ試してみると摂氏から華氏に変わり、そこにとどまります。私のページはhttp://codepen.io/Juan1417/pen/zKZkxyです。onclickイベントのアンカーは一度しか動作しません
やコード：
$(document).ready(function(){
var temp;
var long;
var lat;
if(navigator.geolocation){
navigator.geolocation.getCurrentPosition(function(position){
lat=position.coords.latitude;
long=position.coords.longitude;
var api="http://api.openweathermap.org/data/2.5/weather?lat="+lat+"&lon="+long+"&appid=c873adc18574701f4fb0abe01d927819";
$.getJSON(api,function(data){
var city =data.name;
var country=data.sys.country;
var weather=data.weather[0].main;
temp=data.main.temp;
addIcon(weather);
document.getElementById('location').innerHTML =city+", "+country;
document.getElementById('temperature').innerHTML =(temp-273.13)+"<a id='anc' href='#'> Cº</a>";
$("#anc").click(function(e){
if(document.getElementById('anc').innerHTML==" Cº") document.getElementById('temperature').innerHTML =(temp*1.8+32)+"<a id='anc' href='#'> Fº</a>";
else document.getElementById('temperature').innerHTML =(temp-32/1.8)+"<a id='anc' href='#'> Fº</a>";
});
});
});
}
function addIcon(weather) {
switch(weather){
case 'Dizzle':
document.getElementById('animation').innerHTML ="<div class='icon sun-shower'><div class='cloud'></div><div class='sun'><div class='rays'></div></div><div class='rain'></div></div>";
break;
case 'Rain':
document.getElementById('animation').innerHTML ="<div class='icon rainy'><div class='cloud'></div><div class='rain'></div></div>";
break;
case 'Snow':
document.getElementById('animation').innerHTML ="<div class='icon flurries'><div class='cloud'></div><div class='snow'><div class='flake'></div><div class='flake'></div></div>>/div>";
break;
case 'Clear':
document.getElementById('animation').innerHTML ="<div class='icon sunny'><div class='sun'><div class='rays'></div></div></div>";
break;
case 'Thunderstom':
document.getElementById('animation').innerHTML ="<div class='icon thunder-storm'><div class='cloud'></div><div class='lightning'><div class='bolt'></div><div class='bolt'></div></div></div>";
break;
default:
}
}
});
