如何在jQuery Mobile中同时放置两个位于经纬度的位置

我们需要一次显示两个位置的经度和纬度。我们有两组纬度和经度，如下所示

[{"Longitude":"17.4954","Lattitude":"78.2960","UserID":3},{"Longitude":"17.3616","Lattitude":"78.4747","UserID":3}]

我的问题是仅显示最后一个经度和纬度

$(all).each(function () {
    alert(this.Longitude);
    alert(this.Lattitude);


    debugger;
     directionsDisplay = new google.maps.DirectionsRenderer();
    var mapCenter = new google.maps.LatLng(this.Longitude, this.Lattitude);

    debugger;
    var myOptions = {
        zoom:7,
        mapTypeId: google.maps.MapTypeId.ROADMAP,
        center: mapCenter


    }

    debugger;
    map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);
    directionsDisplay.setMap(map);
  //  directionsDisplay.setPanel(document.getElementById("directions"));  

// marker will be displayed on the lat long position
var marker = new google.maps.Marker({

position:mapCenter,
map: map
});
});

所有变量都动态获取数据，这意味着一段时间后还会有10个位置。有人告诉我我的代码有什么问题。请指导我。

的HTML

<script type="text/javascript" src="http://maps.googleapis.com/maps/api/js?sensor=true"></script>
<div id="map_canvas" style="width:100%;height:100%; position:absolute;"></div>

JAVASCRIPT

var all=[{"Longitude":"17.3616","Lattitude":"78.4747","UserID":3},{"Longitude":"17.4954","Lattitude":"78.2960","UserID":3}];
var map;
 var infowindow = new google.maps.InfoWindow();
$(all).each(function (key, value) {

    if(key == 0){
        map = new google.maps.Map(document.getElementById('map_canvas'), {
          zoom: 6,
          center: new google.maps.LatLng(this.Lattitude, this.Longitude),
          mapTypeId: google.maps.MapTypeId.ROADMAP
        });
    }       

   var marker = new google.maps.Marker({
        position: new google.maps.LatLng(this.Lattitude, this.Longitude),
        map: map
   });

   var content = this.Lattitude+", "+this.Longitude;
   google.maps.event.addListener(marker, 'click', (function(marker, key) {
        return function() {
          infowindow.setContent(content);
          infowindow.open(map, marker);
        }
   })(marker, key));
});
