[英]Toggle Google Maps markers
我从另一篇文章中摘取了一些代码来开始我的工作,但是试图让它做我需要的事情。 我需要设置功能以在选中标记时显示/隐藏标记,还需要为标记类别(例如,步行,钓鱼)分配适当的图标。
首先,我需要使show hide函数正常工作,而目前还没有。
您可以在此处找到演示... http://jsfiddle.net/huMtu/
您遇到的问题是, locations
变量是一个信息数组-实际上不是Google Map上的标记-这意味着您无法在其上调用setVisible()
方法。
您需要做的是将每个标记存储在单独的数组中,然后针对此新数组的元素调用setVisible
方法...。我已经更新了JSFiddle-> http://jsfiddle.net/huMtu/1/
这是JS部分:
var markers = new Array(); // Used to store the google markers
var locations = [
['Bondi Beach', 'Some text goes here<br />text', 'Walk', -33.890542, 151.274856, 4],
['Coogee Beach', 'Some text goes here<br />text', 'Fish', -33.923036, 151.259052, 5],
['Cronulla Beach', 'Some text goes here<br />text', 'Fish', -34.028249, 151.157507, 3],
['Manly Beach', 'Some text goes here<br />text', 'Walk', -33.80010128657071, 151.28747820854187, 2],
['Maroubra Beach', 'Some text goes here<br />text', 'Walk', -33.950198, 151.259302, 1]
];
var map = new google.maps.Map(document.getElementById('map'), {
zoom: 10,
center: new google.maps.LatLng(-33.92, 151.25),
mapTypeId: google.maps.MapTypeId.ROADMAP
});
var infowindow = new google.maps.InfoWindow();
var marker, i;
for (i = 0; i < locations.length; i++) {
marker = new google.maps.Marker({
position: new google.maps.LatLng(locations[i][3], locations[i][4]),
map: map
});
markers.push(marker); // Add the current marker to the array for later processing
google.maps.event.addListener(marker, 'click', (function(marker, i) {
return function() {
infowindow.setContent(locations[i][0]+"<br />"+locations[i][2]+"<br />"+locations[i][1]);
infowindow.open(map, marker);
}
})(marker, i));
}
// == shows all markers of a particular category, and ensures the checkbox is checked ==
function show(category) {
for (var i=0; i<locations.length; i++) {
if (locations[i][2] == category) {
markers[i].setVisible(true); // call the setVisible method of the marker
}
}
}
// == hides all markers of a particular category, and ensures the checkbox is cleared ==
function hide(category) {
for (var i=0; i<locations.length; i++) {
if (locations[i][2] == category) {
markers[i].setVisible(false); // call the setVisible method of the marker
}
}
}
// == show or hide the categories initially ==
show("Walk");
hide("Fish");
