【问题描述】：
我尝试了与这个问题Check/uncheck all button to show/hide all markers Google maps api 几乎相同的事情
但我没有让它工作......我使用了相同的选中/取消选中按钮，但单击这些按钮不会改变我的标记。一次只选中/取消选中复选框。
我也尝试了“最初隐藏”的部分，但所有标记仍然可见..
你能帮帮我吗？我会很感激的！
这是我的代码：
<script type="text/javascript">
var gmarkers = [];
var map = null;
var ib = new InfoBox();
// Function to check/uncheck and show/hide all checkboxes and accordingly all markers
function check() {
$('input[type="checkbox"]').prop("checked", true).change();
}
function uncheck() {
$('input[type="checkbox"]').prop("checked", false).change();
}
// A function to create the marker and set up the event window
function createMarker(latlng,name,html,category) {
var boxText = document.createElement("div");
boxText.style.cssText = "margin-top: 10px; background: rgba(255,255,255,0.7); padding: 10px; border-radius: 10px; color: #000";
boxText.innerHTML = html;
var myOptions = {
content: boxText,
disableAutoPan: false,
maxWidth: 0,
pixelOffset: new google.maps.Size(-100, 0),
zIndex: null,
boxStyle: {
background: "url('tip.png') no-repeat",
width: "250px",
},
closeBoxURL: "",
infoBoxClearance: new google.maps.Size(1, 1),
isHidden: false,
pane: "floatPane",
enableEventPropagation: false
};
var marker = new google.maps.Marker({
position: latlng,
icon: category + ".png",
map: map,
title: name,
zIndex: Math.round(latlng.lat()*-100000)<<5
});
// === Store the category and name info as a marker properties ===
marker.mycategory = category;
marker.myname = name;
gmarkers.push(marker);
google.maps.event.addListener(marker, 'click', function() {
ib.setOptions(myOptions)
ib.open(map, this);
});
} // end createMarker
// == shows all markers of a particular category, and ensures the checkbox is checked ==
function show(category) {
for (var i=0; i<gmarkers.length; i++) {
if (gmarkers[i].mycategory == category) {
gmarkers[i].setVisible(true);
}
}
// == check the checkbox ==
document.getElementById(category+"box").checked = true;
}
// == hides all markers of a particular category, and ensures the checkbox is cleared ==
function hide(category) {
for (var i=0; i<gmarkers.length; i++) {
if (gmarkers[i].mycategory == category) {
gmarkers[i].setVisible(false);
}
}
// == clear the checkbox ==
document.getElementById(category+"box").checked = false;
// == close the info window, in case its open on a marker that we just hid
ib.close();
}
// == a checkbox has been clicked ==
$(".checkbox").change(function() {
var category = $(this).attr("value");
// If checked
if ($(this).is(":checked")) {
show(category);
} else {
hide(category);
}
})
function myclick(i) {
google.maps.event.trigger(gmarkers[i],"click");
}
function initialize() {
var myOptions = {
zoom: 14,
center: new google.maps.LatLng(43.65623,-79.38518),
mapTypeId: google.maps.MapTypeId.ROADMAP,
streetViewControl: false
}
map = new google.maps.Map(document.getElementById("map"), myOptions);
google.maps.event.addListener(map, 'click', function() {
ib.close();
});
$(document).ready(function(){
$.getJSON('data.json', function(data) {
for (var i = 0; i < data.length; i++) {
// obtain the attribues of each marker
var item = data[i];
var point = new google.maps.LatLng(item.ltt, item.lgt);

【问题讨论】：
-
尝试发个jsfiddle，对你有帮助会更容易
-
我已经尝试过了，但我的 data.json 无法正常工作。暂时小提琴是jsfiddle.net/9mgue1g6/2
-
Jsfiddle 对我不起作用，所以我在 codepen 上创建了一个示例并让 data.json 工作：codepen.io/anon/pen/qpwjpv
