Question

当我打开模态弹出窗口来显示地图时，第一次加载了地图，但是当我第二次点击时它不会加载但是如果点击地图div则会出现。

我多次尝试解决这个问题，但我失败了。这是我的代码，我如何打开带有地图的模态

<script src="<?php echo base_url();?>js/farm_gmaps.js"></script>
<script type="text/javascript">

$(document).ready(function(e) 
{
    <?php if($farm['latitude'] && $farm['longitude']){?>
        var lat  = '<?php echo $farm['latitude'];?>';
        var long = '<?php echo $farm['longitude'];?>';
    <?php }else{?>
        var lat  = '21.06656';
        var long = '72.94922';
    <?php }?>

    //initialize(lat,long,""); 

    $('#add_farm_popup').on('show.bs.modal', function (e) 
    {
        //alert("asdasd")
        initialize(lat,long,""); 
    });

});

请注意，打开的弹出文档中的此代码已准备就绪。

这是我的设计代码。

          <div class="right" id="farm_map">
          </div>
          <div class="contact_map">
           <input id="searchTextField" class="form-control" type="text" size="30" placeholder="Enter a location" value="<?php echo $farm['address'];?>">
          </div>

这是我的JavaScript代码

    var geocoder = new google.maps.Geocoder();

function geocodePosition(pos) 
{
    geocoder.geocode
    ({
        latLng: pos
    }, function(responses) 
    {

        if (responses && responses.length > 0) 
        {
            //console.log(responses[0]);
            updateMarkerAddress(responses[0].formatted_address,pos.lat(),pos.lng());
        } 
        else 
        {
            //updateMarkerAddress('Cannot determine address at this location.');
            alert('Cannot determine address at this location.');
        }
    });
}

function updateMarkerAddress(address,lat,lng) 
{
    console.log(lat);
    console.log(lng);

    $("#latitude").val(lat);
    $("#longitude").val(lng);
    $("#address").val(address);
    /*$("#temp_latitude").val(lat);
    $("#temp_longitude").val(lng);

    var split_address = address.split(",");
    var length = split_address.length;
    var city   = split_address[length-3].trim();
    var country = split_address[length-1].trim();

    $("#country").val(country);
    $("#city").val(city);*/

试试这个。这只是一个猜测，但它可能会奏效。

var initialised = false;
var map;
 $('#add_farm_popup').on('show.bs.modal', function (e) 
    {
        If(initialised === false){
            initialize(lat,long,""); 
            initialised = true;
         }else{
            google.maps.event.trigger(map, 'resize');
         }
    });
