加载网站时弹出框

When I load this code below I have a box that pops up with LAT.LNG Any way to remove this please?

    $.getJSON('/aircraft.json', function(data) { 
      $.each( data.aircraft, function(i, value) {


        var myLatlng = new google.maps.LatLng(value.lat, value.lon);
        alert(myLatlng);
        var marker = new google.maps.Marker({
        position: myLatlng,
        icon: '/airplane.jpg',
        map: map,
        title: "text "+value.lon
        });



    });

Assuming this is your site.

In your code there is a function to retrieve and handle the coodrinates from a JSON input /aircrat.json. This function contains a line alert(myLatlng). That line is making your popup.
alert is a function to make a default 'alert' to the user with the contained info.

  $.getJSON('/aircraft.json', function(data) { 
        $.each( data.aircraft, function(i, value) {


            var myLatlng = new google.maps.LatLng(value.lat, value.lon);
            // alert(myLatlng);
            var marker = new google.maps.Marker({
            position: myLatlng,
            icon: '/airplane.jpg',
            map: map,
            title: "text "+value.lon
            });



        });

I have commented out the offending line in the code above.
