我需要这张地图缩小到" 2"当两件事发生时:
我尝试过一些东西,但似乎没什么用。
这是我的代码:
var map;
function initialize() {
var mapOptions = {
center: new google.maps.LatLng(58, 16),
zoom: 2,
mapTypeId: google.maps.MapTypeId.TERRAIN
};
map = new google.maps.Map(document.getElementById("map-canvas"), mapOptions);
}
var seg = {
1:'invesCastProd',
2:'forged',
3: 'airframe',
5: 'corp',
6: 'structurals'
}
var comp = {
1:'structurals',
2:'airfoils',
3: 'airfoils',
4: 'wyman',
5: 'energy',
6: 'strucComp',
7: 'mechHard',
8: 'engineProd',
9: 'corp',
10: 'aero',
12: 'timet',
13: 'specMetals'
}
var myJSON = {};
var myMarkers=[];
$.getJSON("locations.json", function(json1) {
myJSON=json1;
$.each(json1, function(key, data) {
var latLng = new google.maps.LatLng(data.latitude, data.longitude);
// Creating a marker and putting it on the map
var marker = new google.maps.Marker({
position: latLng
});
myMarkers[key]=marker;
marker.setMap(map);
var infoWindow = new google.maps.InfoWindow();
google.maps.event.addListener(marker, 'click', function() {
if (infoWindow) {infoWindow.close();}
infoWindow = new google.maps.InfoWindow({
content: "<h5>" + data.display_name + "</h5>" +
"<div>" + data.street+ "</div>" +
"<div>" + data.city + ", " + data.state + " " + data.postal_code + "</div>" +
"<div class='mapPhoneNum'>" + data.telephone + "</div>" +
"<div><strong>" + seg[data.segment_id] + "</strong></div>" +
"<div><strong>" + comp[data.component_id] + "</strong></div>" +
"<a href=" + data.web_url + ">Website</a>"
});
infoWindow.open(map, marker);
map.setZoom(15);
map.panTo(this.getPosition());
});
filterMarkers = function(category){
//console.log(category);
console.log(category.data());
var component = category.data("component_id");
var segment = category.data("segment_id")
// Clear markers
setMapOnAll(null);
//marker = [];
var filteredMarkers=[];
$.each(myJSON, function(key, data) {
//console.log(key);
if( (myJSON[key].component_id == component) && (myJSON[key].segment_id == segment) ){
console.log("FOUND");
filteredMarkers.push(key);
}
});
for(i=0;i<filteredMarkers.length;i++){
myMarkers[filteredMarkers[i]].setMap(map);
}
}
function setMapOnAll(map) {
for (var i = 0; i < myMarkers.length; i++) {
myMarkers[i].setMap(map);
}
}
});
});
实现这一目标的最佳方法是什么?
答案 0 :(得分:1)
关闭InfoWindow
是个问题。
你需要一个事件监听器。
只需在“标记点击”听众中添加此内容:
(google.maps.event.addListener(marker, 'click', function() {
) - script.js
的第55行。
google.maps.event.addListener(infoWindow,'closeclick',function(){
console.log("CLOSE");
map.setZoom(2);
map.setCenter({lat:58,lng:16});
});
我知道将监听器添加到监听器听起来很奇怪
但那就是你定义infoWindow ...的地方
;)
它有效!
的修改
(我没有处理上面的第二个请求......)
所以,必须将上述内容转移到一个函数中:
function resetMapOrigin(){
console.log("Reseting Map.");
map.setZoom(2);
map.setCenter({lat:58,lng:16});
}
然后在需要时调用此“重置”功能。
;)
google.maps.event.addListener(marker, 'click', function() {
中的:
google.maps.event.addListener(infoWindow,'closeclick',function(){
resetMapOrigin(); // See Plunker line #72
});
并在filterMarkers = function(category){
之后,setMapOnAll(null);
之后:
resetMapOrigin(); // See Plunker line #90
