我有以下代码不起作用。当Jquery和javascript访问同一个变量时，我不知道如何将它们集成在同一个文件中。。。。。像这里一样，纬度1和经度1是两个变量，两者都必须使用。请帮助使其工作

<!DOCTYPE html>

    var latitude1, longitude1;

$(document).ready(function () {
  $(":button").click(function(){
     var add = $("#destination").val();
    $.getJSON("http://maps.googleapis.com/maps/api/geocode/json?address= + add +&sensor=false", function (data) {

           var latitude1 =  data.results[0].geometry.location.lat; 
           vat longitude1 = data.results[0].geometry.location.lng;

    });
    });
});
var map;
var infowindow;
function initialize() {
  var pyrmont = new google.maps.LatLng(latitude1, longitude1);
  map = new google.maps.Map(document.getElementById('map-canvas'), {
    mapTypeId: google.maps.MapTypeId.ROADMAP,
    center: pyrmont,
    zoom: 15
  });
  var request = {
    location: pyrmont,
    radius: 500,
    types: ['store']
  };
  infowindow = new google.maps.InfoWindow();
  var service = new google.maps.places.PlacesService(map);
  service.nearbySearch(request, callback);
}
function callback(results, status) {
  if (status == google.maps.places.PlacesServiceStatus.OK) {
    for (var i = 0; i < results.length; i++) {
      createMarker(results[i]);
    }
  }
}
function createMarker(place) {
  var placeLoc = place.geometry.location;
  var marker = new google.maps.Marker({
    map: map,
    position: place.geometry.location
  });
  google.maps.event.addListener(marker, 'click', function() {
    infowindow.setContent(place.name);
    infowindow.open(map, this);
  });
}
google.maps.event.addDomListener(window, 'load', initialize);
  </script>
  </head>
  <body> 
  <input type="text"  id="destination" /><button type="button">Search</button><br>
    <div id="map-canvas" style="width: 50%; float:left"></div>
    <div style="width:46%; float:left">

</html>

如果您编写var，您将再次定义变量，因此删除var

$（document）.ready（function（）｛

$（"：button"）.点击（function（）｛

 var add = $("#destination").val();
$.getJSON("http://maps.googleapis.com/maps/api/geocode/json?address= + add +&sensor=false", function (data) {

      latitude1 =  data.results[0].geometry.location.lat; 
      longitude1 = data.results[0].geometry.location.lng;

});
});

})；
