Google Maps API v3 won't disable scroll wheel after map loads
提问by Halceyon
I'm implementing google maps on a website and everything is working great, except that I can't seem to be able to disable the scrollwheel after the maps has loaded. If I set the option before the map loads to scrollwheel: false, then the scroll wheel is disabled, but if I try and do it later (I have a checkbox that enables/disables the scroll wheel).
我正在网站上实施谷歌地图，一切正常，除了在地图加载后我似乎无法禁用滚轮。如果我在地图加载到滚轮之前设置选项：false，则滚轮被禁用，但如果我稍后尝试执行此操作（我有一个启用/禁用滚轮的复选框）。
Here are my options for the google map on page load:
以下是我在页面加载时对谷歌地图的选项：
var myOptions = {
zoom: 15,
center: currentPosition,
draggable: true,
scrollwheel: true,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);
map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);
and then after the click event has trigger on the checkbox, I have the following code to disable the scrollwheel. funny enough, the draggable = false is working and prevents me from dragging the map.
然后在单击事件在复选框上触发后，我有以下代码来禁用滚轮。有趣的是，draggable = false 正在工作并阻止我拖动地图。
var checked = $('#chkPin').is(':checked');
log("map active: " + checked);
if (checked) {
map.scrollwheel = false;
map.draggable = false;
map.zoomControl = false;
} else {
map.scrollwheel = true;
map.draggable = true;
map.zoomControl = true;
}

Editing undocumented properties on Maps API objects is not supported and can lead to unpredictable results. You shouldn't directly modify properties on a map object. Instead, modify the properties using one of the documented options:
不支持在 Maps API 对象上编辑未记录的属性，这可能会导致不可预测的结果。您不应直接修改地图对象的属性。相反，使用记录的选项之一修改属性：
Object specific defined getters/setters:
对象特定定义的 getter/setter：
map.setOptions({'scrollwheel': false});
MVCObject generic getters/setters:
MVCObject 通用 getter/setter：
map.set('scrollwheel', false);
var isScrollWheelEnabled = map.get('scrollwheel');
Both of these options successfully disabled scrollwheel zooming of the map after it had already been initialized.
这两个选项都在地图初始化后成功禁用了地图的滚轮缩放。
