Question

我将这一条用于对用户进行地理定位,我需要<代码>的现行Lat和<代码>的现行L。储存在:

    <script>  

  window.onload = function() {
    var startPos;

    if (navigator.geolocation) {
      navigator.geolocation.getCurrentPosition(function(position) {
        startPos = position;
        document.getElementById("currentLat").innerHTML = startPos.coords.latitude;
        document.getElementById("currentLon").innerHTML = startPos.coords.longitude;
      });
    }
  };

</script>

我在这里需要这些价值观:

http://api.flickr.com/services/rest/?method=flickr.photos.search&api_key=my_key&radius_units=km&radius=5&lat= XXX &lon= XXX &jsoncallback=?

我如何通过 j获得这些价值观,并立即将这些价值观置于URL? 什么最快?

感谢@Manuel,但我首先利用了它,因为我不需要错误的功能,而只是为了保持简单,我可以理解它,而没有工作吗?

$(document).ready(function() {
  navigator.geolocation.getCurrentPosition(function(position) {
    var lat = position.coords.latitude;
    var lon = position.coords.longitude;
  var JSONURL = "http://api.flickr.com/services/rest/?method=flickr.photos.search&api_key=my_key&format=json&privacy_filter=1&media=photos&tag=london&minwidth=700&has_geo=1&accuracy=11&content_type=1&extras=geo,owner_name,url_m&page=1&radius_units=km&radius=5&"+lat+"&lon="+lon+"&jsoncallback=?";
  jQuery.getJSON( JSONURL, getJSONimages);
  function getJSONimages(data) {
    var htmlString = "";
    $.each(data.photos.photo, function(i,item){
    var itemTitle = item.title;
                }); 
    $( #slideshow ).html(htmlString);
    $( #slideshow ).slideshow({
                timeout: 3000,
                type:  random ,
                fadetime: 2000
            });   
  } }
  })

navigator.geolocation.getCurrentPosition(function(position) {
    var lat = position.coords.latitude;
    var lon = position.coords.longitude;

    var url =  http://api.flickr.com/services/rest/?method=flickr.photos.search&api_key=my_key&radius_units=km&radius=5&lat= +lat+ &lon= +lon+ &jsoncallback=? ;
    // console.log(url);
}, function(error) {
    console.log("Something went wrong: ", error);
});
