我使用谷歌地图API (v3)在页面上绘制一些地图。我想做的一件事是当你在地图上滚动鼠标滚轮时禁用缩放，但我不知道该怎么做。
我已经禁用了scaleControl(即删除缩放UI元素)，但这并不能阻止滚轮缩放。
下面是我的函数的一部分(这是一个简单的jQuery插件):
$.fn.showMap = function(options, addr){
options = $.extend({
navigationControl: false,
mapTypeControl: false,
scaleControl: false,
draggable: false,
mapTypeId: google.maps.MapTypeId.ROADMAP
}, options);
var map = new google.maps.Map(document.getElementById($(this).attr('id')), options);
// Code cut from this example as not relevant
};
截至目前(2017年10月)，谷歌已经实现了一个特定的属性来处理缩放/滚动，称为手势处理。它的目的是处理移动设备的操作，但它也修改了桌面浏览器的行为。以下是官方文件:
function initMap() {
var locationRio = {lat: -22.915, lng: -43.197};
var map = new google.maps.Map(document.getElementById('map'), {
zoom: 13,
center: locationRio,
gestureHandling: 'none'
});
The available values for gestureHandling are:
'greedy': The map always pans (up or down, left or right) when the user swipes (drags on) the screen. In other words, both a one-finger swipe and a two-finger swipe cause the map to pan.
'cooperative': The user must swipe with one finger to scroll the page and two fingers to pan the map. If the user swipes the map with one finger, an overlay appears on the map, with a prompt telling the user to use two fingers to move the map. On desktop applications, users can zoom or pan the map by scrolling while pressing a modifier key (the ctrl or ⌘ key).
'none': This option disables panning and pinching on the map for mobile devices, and dragging of the map on desktop devices.
'auto' (default): Depending on whether the page is scrollable, the Google Maps JavaScript API sets the gestureHandling property to either 'cooperative' or 'greedy'
简而言之，您可以轻松地将设置强制为“始终可缩放”(“贪婪”)、“永不可缩放”(“none”)或“用户必须按CRTL/⌘才能启用缩放”(“合作”)。
以防万一，你正在使用gaps .js库，它使它更简单地做一些事情，如地理编码和自定义引脚，下面是如何使用从前面的答案中学到的技术来解决这个问题。
var Gmap = new GMaps({
div: '#main-map', // FYI, this setting property used to be 'el'. It didn't need the '#' in older versions
lat: 51.044308,
lng: -114.0630914,
zoom: 15
});
// To access the Native Google Maps object use the .map property
if(Gmap.map) {
// Disabling mouse wheel scroll zooming
Gmap.map.setOptions({ scrollwheel: false });
}

在Maps API的版本3中，你可以在MapOptions属性中简单地将scrollwheel选项设置为false:
options = $.extend({
scrollwheel: false,
navigationControl: false,
mapTypeControl: false,
scaleControl: false,
draggable: false,
mapTypeId: google.maps.MapTypeId.ROADMAP
}, options);
如果你正在使用版本2的地图API，你将不得不使用disableScrollWheelZoom() API调用如下:
map.disableScrollWheelZoom();
在Maps API的版本3中，滚动轮缩放默认是启用的，但在版本2中，它是禁用的，除非通过enableScrollWheelZoom() API调用显式启用。
我用这个简单的例子来做
jQuery
$('.map').click(function(){
$(this).find('iframe').addClass('clicked')
}).mouseleave(function(){
$(this).find('iframe').removeClass('clicked')
});
CSS
.map {
width: 100%;
}
.map iframe {
width: 100%;
display: block;
pointer-events: none;
position: relative; /* IE needs a position other than static */
}
.map iframe.clicked {
pointer-events: auto;
}
或者使用gmap选项
function init() {
var mapOptions = {
scrollwheel: false,
