在外部div google maps api v3中关闭信息窗口
[英]closing an infowindow in an external div google maps api v3
问题描述
已更新以显示页面的所有代码和最终解决方案
我正在创建一个Google地图信息窗口，该窗口填充了固定在屏幕右侧的潜水。 我有它，所以一次只打开一个信息窗口，但是我似乎无法关闭该信息窗口。 我将标记和信息窗口内容放入一个数组中。 这是我的代码：
jQuery( '#infocanvas' ).hide();
jQuery( '#close-infocanvas' ).hide();
var map;
var overlay;
USGSOverlay.prototype = new google.maps.OverlayView();
var directionsDisplay;
var directionsService = new google.maps.DirectionsService();
directionsVisible = false;
// Initialize the map and the custom overlay.
function initialize() {
directionsDisplay = new google.maps.DirectionsRenderer();
var styles = [ {
featureType: "all",
elementType: "labels",
stylers: [
{ visibility: "simplified" }
]
},{
featureType: "poi",
elementType: "labels",
stylers: [
{ visibility: "on" }
]
},{
featureType: "labels.text",
elementType: "labels",
stylers: [
{ visibility: "off" }
]
},{
featureType: "road",
elementType: "geometry",
stylers: [
{ lightness: 100 },
{ visibility: "simplified" }
]
},{
featureType: "road",
elementType: "labels",
stylers: [

]
}
];
// map.controls[google.maps.ControlPosition.TOP_LEFT].push($('<div id="infowindow"/>')[0]);

我认为信息窗口有些混乱。 您定义了一个名为“ infocanvas”的新信息窗口，但是随后您想要关闭名为“ infowindow”的信息窗口。 实际上，您正在使用简单的DIV。
在事件侦听器“映射，单击”中，只需像在代码顶部一样隐藏DIV信息画布即可：
google.maps.event.addListener(map, "click", function(event) {
jQuery( '#infocanvas' ).hide();
jQuery( '#close-infocanvas' ).hide();
});
还有一件事，var map应该不在initialize函数之外。 只要：
var map;
然后在函数“初始化”中定义此变量的值
map = new google.maps.Map (document.getElementById ("map-canvas'), MapOptions);
没有单词“ var”。
因此，变量“ map”将在代码的任何部分可用。 此时，第343行中的代码无法访问变量“地图”。
“ var标记”也应该不在初始化函数中，并且您必须创建特定的函数才能将标记添加到地图。
必须通过将代码细分为更小的函数来最小化“初始化”函数的总结。 这样，您可以组织代码，并且更容易检测错误。
您将在带有多个标记的地图中找到有关此信息的更多信息。
