Question

我有这种模式：

<form id="contactModal">
<div id="mymodal2" class="" tabindex="-1" role="dialog" aria-labelledby="myLargeModalLabel" aria-hidden="true">
     <div class="modal-dialog">
           <div class="modal-content">
              <div class="modal-header">                  
              <button type="button" class="close" data-dismiss="modal"><span aria-hidden="true">×</span><span class="sr-only">Close</span></button>
                <span class="modal-title th2" id="lblModalLabel" name="lblModalLabel">Contact</span>
            </div>
            <div class="modal-body">

如果我不添加class="modal"喜欢

<div id="mymodal2" class="fade modal" tabindex="-1" role="dialog" aria-labelledby="myLargeModalLabel" aria-hidden="true">

我对地图没有任何问题，问题是当我尝试添加模态类时，我的地图消失了，为什么会发生？

--- ---更新

如果我运行没有模态类的应用程序，如：

<div id="mymodal" class="" tabindex="-1" role="dialog" aria-labelledby="myLargeModalLabel" aria-hidden="true" >

然后打开谷歌浏览器检查器并通过它添加类。它将地图加载到模态中。

这是我的JS代码：

 try {
            map = new GMaps({
                div: '#gmap_marker',
                lat: 19.4368277,
                lng: -99.1905598
            });


            map.addMarker({
                lat: 19.4368277,
                lng: -99.1905598,
                title: New City",
                infoWindow: {
                    content: '<strong>City</strong>'
                }
            });
            console.log("gmap processed");
        }
        catch (e) {
            alert(e);
        }

    $("#btnFirstMap").click(function () {


        try {
            map = new GMaps({
                div: '#gmap_marker',
                lat: 19.4368277,
                lng: -99.1905598
            });


            map.addMarker({
                lat: 19.4368277,
                lng: -99.1905598,
                title: "FirstMap",
                infoWindow: {
                    content: '<strong>City2</strong>'
                }
            });
        }
        catch (e) {
            alert(e);
        }

    });

    $("#btnCity3").click(function () {


        try {
            map = new GMaps({
                div: '#gmap_marker',
                lat: 18.6490907,
                lng: -91.8218911
            });


            map.addMarker({
                lat: 18.6490907,
                lng: -91.8218911,
                title: "City3,
                infoWindow: {
                    content: '<strong>City3</strong>'
                }
            });
        }
        catch (e) {
            alert(e);
        }

    });

请务必：

1）显式设置地图容器大小，例如通过CSS：

div#map {
    width: 560px !important;
    height: 600px !important;
}

2）通过resize事件显示模态对话框后重新加载地图：

$('#myModal').on('show.bs.modal', function(e) {
    var map = createMap();
    google.maps.event.addListenerOnce(map, 'idle', function() {
        google.maps.event.trigger(map, 'resize'); 
    });
})

示例

$(document).ready(function() { $('#myModal').on('show.bs.modal', function(e) { var map = createMap(); google.maps.event.addListenerOnce(map, 'idle', function() { google.maps.event.trigger(map, 'resize'); }); }) }); function createMap() { var mapControl = new GMaps({ div: '#map', lat: -12.043333, lng: -77.028333 }); mapControl.addMarker({ lat: -12.043333, lng: -77.03, title: 'Lima', details: { database_id: 42, author: 'HPNeo' }, click: function(e) { if (console.log) console.log(e); alert('You clicked in this marker'); } }); return mapControl.map; }

div#map { width: 560px !important; height: 600px !important; }
