本文介绍了当嵌套在div标记中时,地图不会显示在Google Maps JavaScript API v3上的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我试图放置显示地图的 div
标签(< div id =map-canvas>< / div>
)在另一个 div
内,但它不以那种方式显示地图。它是一个CSS或JavaScript问题?或者它只是API的工作方式?
这里是我的嵌套 div
的代码:
<!DOCTYPE html>
< html>
< head>
< title>简易地图< /标题>
< meta name =viewportcontent =initial-scale = 1.0,user-scalable = no>
< meta charset =utf-8>
< style>
html,body,#map-canvas {
margin:0;
padding:0;
身高:100%;
}
< / style>
< script src =https://maps.googleapis.com/maps/api/js?v=3.exp&sensor=false>
< / script>
< script>
var map;
函数initialize(){
var mapOptions = {
zoom:8,
center:new google.maps.LatLng(-34.397,150.644),
mapTypeId: google.maps.MapTypeId.ROADMAP
};
map = new google.maps.Map(document.getElementById('map-canvas'),
mapOptions);
}
google.maps.event.addDomListener(window,'load',initialize);
< / script>
< / head>
< body>
< div> <! - ommiting this div将显示地图 - >
< div id =map-canvas>< / div>
< / div>
< / body>
< / html>
解决方案
添加 style =width :100%;身高:100%;
给div看看有什么作用
不是 #map_canvas
但主分区
示例
<身体GT;
< div style =height:100%; width:100%;>
< div id =map-canvas>< / div>
< / div>
< / body>
这里还有其他一些答案,解释为什么这是必要的
I'm trying to put the div
tag that shows the map (<div id="map-canvas"></div>
) inside another div
, but it doesn't show the map that way. Is it a CSS or a JavaScript problem? Or is it just the way the API works?
Here's my code with the the nested div
:
<!DOCTYPE html>
<html>
<head>
<title>Simple Map</title>
<meta name="viewport" content="initial-scale=1.0, user-scalable=no">
<meta charset="utf-8">
<style>
html, body, #map-canvas {
margin: 0;
padding: 0;
height: 100%;
}
</style>
<script src="https://maps.googleapis.com/maps/api/js?v=3.exp&sensor=false">
</script>
<script>
var map;
function initialize() {
var mapOptions = {
zoom: 8,
center: new google.maps.LatLng(-34.397, 150.644),
mapTypeId: google.maps.MapTypeId.ROADMAP
};
map = new google.maps.Map(document.getElementById('map-canvas'),
mapOptions);
}
google.maps.event.addDomListener(window, 'load', initialize);
</script>
</head>
<body>
<div> <!-- ommiting this div will show the map -->
<div id="map-canvas"></div>
</div>
</body>
</html>
解决方案
Add style="width:100%; height:100%;"
to the div see what that does
not to the #map_canvas
but the main div
example
<body>
<div style="height:100%; width:100%;">
<div id="map-canvas"></div>
</div>
</body>
