巨大的谷歌地图控件(可能的错误？)
use*_*888 56 css google-maps google-maps-api-3
我首先注意到我的谷歌地图控件在我自己的网络应用程序上不成比例地大(见下文).
最初我认为我的一些CSS在控件上使用Google的CSS; 然而,访问谷歌自己的网页告诉我这件事并不是孤立的......
以下是其文档的地图:https://developers.google.com/maps/documentation/javascript/examples/control-positioning
大型控件也出现在他们文档的每一页上.我尝试了不同的机器和不同的浏览器(Chrome和Firefox).
我还尝试了其他使用Google Maps API的网站,并在某些情况下看到了类似的现象.
还有其他人遇到过同样的问题吗？

事实证明这不是一个错误.在这里查看更多:
2018年8月13日03:56 PM报告问题Google Maps JavaScript API每周频道(3.34)将使用更大的控制UI.
随着我们看到各种设备上触摸操作的增加,我们调整了控制UI以适应手指触摸和鼠标点击.
通过使用v = quarterly,v = 3,v = 3.33或v = 3.32加载API,可以选择不使用此功能.注意:对退役版本的请求将收到默认频道,请参阅1.
如果您对新控制UI有任何要求或其他问题,请告诉我们.
在加载API以使用较小的控件时,请使用v = quarterly,v = 3,v = 3.33或v = 3.32.
编辑:
请参阅@Jonny van Beek关于如何将Google地图的控件缩放到您选择的大小的答案.
请参阅@garethdn和@Peter(下面)中的答案,了解如何使用您自己的自定义控件替换Google的大型控件.
- 这是一个**临时解决方案**,因为版本将更新并变得不可用.也就是说,Google可能会在更高版本中提供一些自定义设置.如果您需要完全控制这些按钮,最好使用@garethdn answer并创建自己的自定义控件. (7认同)
- 自定义控件也不考虑所有控件,特别是pegman,旋转/倾斜和地形/标签选项在其示例中缺失且未记录. (3认同)

看起来谷歌现在已经承认这一点,并提供了一个(目前未记录的)功能,通过在创建地图时传入"controlSize"来更改UI缩放.
在此处查看Google的评论.
JSFiddle 在这里(来自上面的评论).
示例代码:
var map;
function initMap() {
map = new google.maps.Map(document.getElementById('map'), {
center: {lat: -34.397, lng: 150.644},
zoom: 8,
controlSize: 32,
});
}
注意:40是当前的默认值(对应于此问题所涉及的大型控件).我发现25与之前的控件大致相同.
- 鉴于api版本3.33的丢失，我们现在被迫降至3.34+。因此v3.35很好地支持controlSize。我发现controlSize：26看起来最接近3.33外观。具有强制3.35和controlSize的JSFiddle：此处为26：https：//jsfiddle.net/blalond/8q6fjthg/ (2认同)
强烈反对之后，Google现在发布了一个示例，说明如何替换默认（大型）控件：https : //developers.google.com/maps/documentation/javascript/examples/control-replacement
这是Google发布的代码：

- 我在选择的答案中提到了这一点，但是一个明显的问题是自定义控件并不能说明所有控件，尤其是示例中缺少衣夹人，旋转/倾斜和terrain / labels选项，这些文档没有记录。 (3认同)
对于那些不愿意通过指定较旧版本的API退出的用户而言，创建自定义控件相对简单。以下将创建两个button元素来放大和缩小。
defaultMapOptions: google.maps.MapOptions = {
// Hide Google's default zoom controls
zoomControl: false
};
initializeMap(el: HTMLElement, options?: google.maps.MapOptions): google.maps.Map {
let opts = Object.assign({}, this.defaultMapOptions, options);
let map = new google.maps.Map(el, opts);
let zoomControlsDiv = document.createElement('div');
// Add a class to the container to allow you to refine the position of the zoom controls
zoomControlsDiv.classList.add('google-map-custom-zoom-controls');
this.createCustomZoomControls(zoomControlsDiv, map);
map.controls[google.maps.ControlPosition.RIGHT_BOTTOM].push(zoomControlsDiv);
return map;
}
createCustomZoomControls(controlDiv: HTMLDivElement, map: google.maps.Map) {
let zoomInControlUI: HTMLButtonElement = document.createElement('button');
let zoomOutControlUI: HTMLButtonElement = document.createElement('button');
let zoomControls: HTMLButtonElement[] = [zoomInControlUI, zoomOutControlUI];
// List of classes to be applied to each zoom control
let buttonClasses: string[] = ['btn', 'btn-primary', 'btn-sm'];
zoomInControlUI.innerHTML = `+`;
zoomOutControlUI.innerHTML = `−`;
zoomControls.forEach(zc => {
zc.classList.add(...buttonClasses);
controlDiv.appendChild(zc);
});
google.maps.event.addDomListener(zoomInControlUI, 'click', () => map.setZoom(map.getZoom() + 1));
google.maps.event.addDomListener(zoomOutControlUI, 'click', () => map.setZoom(map.getZoom() - 1));
}
let map = this.initializeMap(myGoogleMapContainerElement);
