如何自定义谷歌地图api(v3 javascript)缩放按钮到我自己的图像.
Mau*_*ähä 19
我在聚会上迟到了,但这是我的两分钱.
你基本上有两个选择:
选项1:您可以自己使用HTML/CSS创建控件,然后可以使用绝对位置或类似方法将其放置在正确的位置上.即使这在生产中有效,我也不喜欢这样,因为元素的HTML/CSS不会在显示地图的同时加载.此外,您正在分离控件的HTML/CSS代码,因此在不同页面重用相同的映射会更加困难.例如"我忘了添加控件吗？"
选项2:您创建一个自定义控件,其外观和感觉您喜欢的缩放控制器.以下是实践中的相关代码.
简而言之,您需要先调用以下命令禁用普通的UI控制器:
var mapOptions = {
zoom: 12,
center: chicago,
/* Disabling default UI widgets */
disableDefaultUI: true // <-- see this line
}
然后你只需创建控制器并使用它.
HTML:
...
<div id="map-canvas"></div>
...
CSS:
html, body, #map-canvas {
height: 100%;
margin: 0px;
padding: 0px;
}
JavaScript的:
var map;
var chicago = new google.maps.LatLng(41.850033, -87.6500523);
/**
* The ZoomControl adds +/- button for the map
*
*/
function ZoomControl(controlDiv, map) {
// Creating divs & styles for custom zoom control
controlDiv.style.padding = '5px';
// Set CSS for the control wrapper
var controlWrapper = document.createElement('div');
controlWrapper.style.backgroundColor = 'white';
controlWrapper.style.borderStyle = 'solid';
controlWrapper.style.borderColor = 'gray';
controlWrapper.style.borderWidth = '1px';
controlWrapper.style.cursor = 'pointer';
controlWrapper.style.textAlign = 'center';
controlWrapper.style.width = '32px';
controlWrapper.style.height = '64px';
controlDiv.appendChild(controlWrapper);
// Set CSS for the zoomIn
var zoomInButton = document.createElement('div');
zoomInButton.style.width = '32px';
zoomInButton.style.height = '32px';
/* Change this to be the .png image you want to use */
zoomInButton.style.backgroundImage = 'url("http://placehold.it/32/00ff00")';
controlWrapper.appendChild(zoomInButton);
// Set CSS for the zoomOut
var zoomOutButton = document.createElement('div');
zoomOutButton.style.width = '32px';
zoomOutButton.style.height = '32px';
/* Change this to be the .png image you want to use */
zoomOutButton.style.backgroundImage = 'url("http://placehold.it/32/0000ff")';
controlWrapper.appendChild(zoomOutButton);
// Setup the click event listener - zoomIn
google.maps.event.addDomListener(zoomInButton, 'click', function() {
map.setZoom(map.getZoom() + 1);
});
// Setup the click event listener - zoomOut
google.maps.event.addDomListener(zoomOutButton, 'click', function() {
map.setZoom(map.getZoom() - 1);
});
}
function initialize() {
var mapDiv = document.getElementById('map-canvas');
var mapOptions = {
zoom: 12,
center: chicago,
/* Disabling default UI widgets */
disableDefaultUI: true
}
map = new google.maps.Map(mapDiv, mapOptions);
// Create the DIV to hold the control and call the ZoomControl() constructor
// passing in this DIV.
var zoomControlDiv = document.createElement('div');
var zoomControl = new ZoomControl(zoomControlDiv, map);
zoomControlDiv.index = 1;
map.controls[google.maps.ControlPosition.TOP_LEFT].push(zoomControlDiv);
}
initialize();
注意:此代码不包含任何花哨的图标等,只是占位符.因此,您可能需要调整它以满足您的需求.此外,请记住为谷歌地图api v3 javascript添加HTML5普通标签和脚本包含.我<div id="map-canvas"></div>之所以加入,只是因为对身体其他部位的需求非常明显.
现场观看:这是jsfiddle的例子
干杯.

var myLatlng = new google.maps.LatLng(-33.90224, 151.20215);
var mapOptions = {
zoom: 15,
center: myLatlng,
Marker: true,
panControl: false,

}
map = new google.maps.Map(mapDiv, mapOptions);
var marker = new google.maps.Marker({
position: myLatlng,
map: map,
title:"Hello World!"
});
// Create the DIV to hold the control and
// call the HomeControl() constructor passing

var homeControlDiv = document.createElement('div');
var homeControl = new HomeControl(homeControlDiv, map);

<body>
<div id="map-canvas"></div>
<div id="zoomout" style="border:1px solid; width:150px; cursor:pointer; margin-bottom:20px;">ZOOM ME OUT</div>
<div id="zoomin" style="border:1px solid; width:150px; cursor:pointer; ">ZOOM ME IN</div>
</body>
</html>
我用 CSS 的方式做到了：
#map-container .gm-style > .gmnoprint > .gmnoprint { background: url(/images/map-zoom-controls.png) no-repeat center center !important; width: 42px !important; height: 68px !important; }
#map-container .gm-style > .gmnoprint > .gmnoprint > div > img { display: none !important; }
#map-container .gm-style > .gmnoprint > .gmnoprint div[title="Zoom in"] { top: 2px !important; left: 2px !important; width: 38px !important; height: 31px !important; }
#map-container .gm-style > .gmnoprint > .gmnoprint div[title="Zoom out"] { top: 35px !important; left: 2px !important; width: 38px !important; height: 30px !important; }
这是针对具有以下内容的图像：宽度：42px；高度：68px；
进行自己的调整。
