单击并移动鼠标后，Google地图停止工作

时间：2015-05-28 06:17:59

标签： javascript jquery google-maps-api-3

我有以下代码，它有两个按钮，一个用于显示地图，另一个用于隐藏它并显示一个段落。问题是，我第一次打开页面时会显示地图，但是一旦我尝试移动它以找到所选位置，它就会停止显示地图。

您需要触发＆＃39;调整大小＆＃39;显示后在地图上显示事件，然后设置中心的大小：

function populateMap() {
    $("#para").hide();
    $("#myMap").show();
    google.maps.event.trigger(map,'resize');
    map.setCenter(centreLoc);
}

代码段（已删除signed_in=true，在SO代码段中播放效果不佳）：

＆＃13; 
function hideMap() {
        $("#myMap").hide();
        $("#para").show();

我提出了错误的风格

<div id="myMap"></div>
<div id="para" style="width: 380px; height: 400px;"><p>This is it</p></div>

到这一个

<div id="myMap" style="width: 380px; height: 400px;"></div>
<div id="para"><p>This is it</p></div>
