我有以下代码:
父页面:
<!DOCTYPE html>
<html>
<head>
</head>
<body>
<a href=# onclick='showMap()'>show map <a>
<div id="map-canvas"></div>
</body>
<script>
function showMap(){
window.open('map.html','map','width=600,height=400');
}
</script>
</html>
map .html:
<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="initial-scale=1.0, user-scalable=no">
<meta charset="utf-8">
<title>Info windows</title>
<style>
html, body, #map-canvas {
height: 100%;
margin: 0px;
padding: 0px
}
</style>
<script src="https://maps.googleapis.com/maps/api/js?v=3.exp"></script>
<script>
function initialize() {
var myLatlng = new google.maps.LatLng(-25.363882,131.044922);
var mapOptions = {
zoom: 4,
center: myLatlng
};
var map = new google.maps.Map(document.getElementById('map-canvas'), mapOptions);
var marker = new google.maps.Marker({
position: myLatlng,
map: map,
title: 'Uluru (Ayers Rock)'
});
}
google.maps.event.addDomListener(window, 'load', initialize);
</script>
</head>
<body>
<div id="map-canvas"></div>
</body>
</html>
如您所见，我使用硬编码值进行 map 标记渲染:
var myLatlng = new google.maps.LatLng(-25.363882,131.044922);
我可以将这些值从父页面传递到弹出窗口吗？
最佳答案
既然你问的只是如何从父级传递到弹出一个选项将是查询字符串参数:
<a href=# onclick='showMap(-25.363882,131.044922)'>show map <a>
function showMap(lat,lng){
window.open('map.html?lat='+lat+'&lng ='+lng,'map','width=600,height=400');
}
然后在 map.html 中收集这些值并使用..
更新:可以通过多种方式收集查询字符串值，通过快速搜索查看选项
function getParameterByName(name) {
name = name.replace(/[\[]/, "\\[").replace(/[\]]/, "\\]");
var regex = new RegExp("[\\?&]" + name + "=([^&#]*)"),
results = regex.exec(location.search);
return results === null ? "" : decodeURIComponent(results[1].replace(/\+/g, " "));
}
var lat = getParameterByName('lat');
var lon = getParameterByName('lon');

我测试过，一切正常:
生成的 index.html:
<!DOCTYPE html>
<html>
<head>
</head>
<body>
<a href=# onclick='showMap(-25.363882,131.044922)'>show map <a>
<div id="map-canvas"></div>
</body>
<script>
function showMap(lat,lng){
window.open('map.html?lat='+lat+'&lng ='+lng,'map','width=600,height=400');
}
</script>
</html>
和生成的 map.html:
<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="initial-scale=1.0, user-scalable=no">
<meta charset="utf-8">
<title>Info windows</title>
<style>
html, body, #map-canvas {
height: 100%;
margin: 0px;
padding: 0px
}
</style>
<script src="https://maps.googleapis.com/maps/api/js?v=3.exp"></script>
<script>
function getParameterByName(name) {
name = name.replace(/[\[]/, "\\[").replace(/[\]]/, "\\]");
var regex = new RegExp("[\\?&]" + name + "=([^&#]*)"),
results = regex.exec(location.search);
return results === null ? "" : decodeURIComponent(results[1].replace(/\+/g, " "));
}
var lat = getParameterByName('lat');
var lon = getParameterByName('lon');
function initialize() {
var myLatlng = new google.maps.LatLng(lat, lon);
var mapOptions = {
zoom: 4,
center: myLatlng
};
var map = new google.maps.Map(document.getElementById('map-canvas'), mapOptions);
var marker = new google.maps.Marker({
position: myLatlng,
map: map,
title: 'Uluru (Ayers Rock)'
});
}
google.maps.event.addDomListener(window, 'load', initialize);
</script>
</head>
<body>
<div id="map-canvas"></div>
</body>
</html>
