的html代碼：

<ul class="nav nav-tabs"> 
    <li class="active"> 
     <a data-toggle="tab" href="#home"><b>Overview</b></a> 
    </li> 
    <li> 
     <a data-toggle="tab" href="#menu1"><b>Facilities</b></a> 
    </li> 
</ul> 


<div class="tab-content"> 
<div id="home" class="tab-pane fade in active"> 
    <p>Welcome</p> 
</div> 
<div id="menu1" class="tab-pane fade"> 
    //Google map 
    <div id="map"></div> 
    <input type="text" id="latitude" style="display:none;" placeholder="Latitude"/> 
    <input type="text" id="longitude" style="display:none;" placeholder="Longitude"/> 
    <input type="button" id="show_btn" value="show markers" onClick="showMarkers();" style="display:none;" /> 
    <div id="test"></div> 
</div> 

在這段代碼中，當我點擊主頁選項卡的文本會打開，但是當我點擊菜單1選項卡的內容被顯示，但谷歌地圖沒有顯示。我想在菜單1選項卡上打開Goog​​le地圖。那麼，我怎樣才能做到這一點，請幫助解決這個問題？

謝謝

我是想你的代碼，但我覺得有什麼missing.So，我創建了一個方式來加載這些選項卡中一張簡單的地圖。地圖不加載到選項卡中的問題是因爲地圖變成隱藏的元素，所以爲了使其可見，我們必須在點擊選項卡時重新初始化地圖。我已經寫了下面的代碼，希望這個答案解決你的問題。

function initMap() { 
 
     var uluru = {lat: -25.363, lng: 131.044}; 
 
     var map = new google.maps.Map(document.getElementById('map'), { 
 
      zoom: 4, 
 
      center: uluru 
 
     }); 
 
     var marker = new google.maps.Marker({ 
 
      position: uluru, 
 
      map: map 
 
     }); 
 
     } 
 

 
//Bind click handlers - Here's the important part 
 
$('.nav a').on('click', function() { 
 
    setTimeout(function(){ 
 
     google.maps.event.trigger(map, 'resize'); 
 
    }, 50); 
 
});

#map{ height:400px}
