我的 WinJS Windows 8 应用程序的页面上有 Bing 地图。
地图有几个图钉,每个图钉都有自己的信息框。单击图钉时,它会正确显示信息框及其内容。内容包含链接到 Windows 8 应用程序中不同页面的超链接。应用程序可以正确导航到此页面,但是后退按钮停止工作,并且也无法访问应用程序栏。(导航到页面通常可以正常工作)
我认为页面导航方式和导航器记录状态的方式出了点问题。我是新手,所以它也可能只是一个愚蠢的问题。
这是页面的 .js 文件中的代码:
// For an introduction to the Page Control template, see the following documentation:
// http://go.microsoft.com/fwlink/?LinkId=232511
(function () {
"use strict";
WinJS.UI.Pages.define("/pages/testBing/testBing.html", {
// This function is called whenever a user navigates to this page. It
// populates the page elements with the app's data.
ready: function (element, options) {
// TODO: Initialize the page here.
Microsoft.Maps.loadModule('Microsoft.Maps.Map', { callback: initMap });
}
});
})();
var pinInfobox = null;
function initMap() {
try {
var mapOptions =
{
credentials: "credentials",
center: new Microsoft.Maps.Location(-33.961176, 22.420985),
mapTypeId: Microsoft.Maps.MapTypeId.road,
zoom: 5
};
var mapDiv = document.querySelector("#mapdiv");
map = new Microsoft.Maps.Map(mapDiv, mapOptions);
centerPosition();
}
catch (e) {
var md = new Windows.UI.Popups.MessageDialog(e.message);
md.showAsync();
}
}
function addPushPin(location) {
map.entities.clear();
var pushpin = new Microsoft.Maps.Pushpin(location, null);
pinInfobox = new Microsoft.Maps.Infobox(new Microsoft.Maps.Location(0, 0), { title: 'My Pushpin', visible: true, description: "<a href='/pages/player/player.html'>Profile</a>" });
Microsoft.Maps.Events.addHandler(pushpin, 'click', displayInfobox);
Microsoft.Maps.Events.addHandler(map, 'viewchange', hideInfobox);
map.entities.push(pushpin);
map.entities.push(pinInfobox);
}
function hideInfobox(e) {
pinInfobox.setOptions({ visible: false });
}
function centerPosition() {
var geolocator = new Windows.Devices.Geolocation.Geolocator();
geolocator.getGeopositionAsync().then(function (loc) {
var mapCenter = map.getCenter();
mapCenter.latitude = loc.coordinate.latitude;
mapCenter.longitude = loc.coordinate.longitude;
map.setView({ center: mapCenter, zoom: 15 });
addPushPin(mapCenter);
});
}
function displayInfobox(e) {
pinInfobox.setOptions({ title: e.target.Title, innerHTML: e.target.Description, visible: true, offset: new Microsoft.Maps.Point(0, 25) });
pinInfobox.setLocation(e.target.getLocation());
}
