我有以下bing地图:https://www.bob-elliot.co.uk/locateV2.php
当在左侧列表中选择商店时,地图自动以该图钉为中心,我现在需要做的是调用该图钉的click()手柄(或显示相关的InfoBox)。
问题是,我正在将引脚推入名为Microsoft.Maps.EntityCollection();
的{{1}},所以我无法直接调用map.entities.get() - 或者更确切地说 - 如果我尝试这样调用它( )不会返回任何东西。
请注意此代码段底部的dataLayer
功能,我已对相关行进行了注释。
我如何调用点击事件?
zoomMap()
答案 0 :(得分:4)
由于某些原因,e.target似乎没有进入displayInfobox功能。
我已经修改了你的代码,在2,3个位置稍微修改了一些东西以获得接近你预期的点。请在下面查看:
var map = null;
var dataLayer = null;
var infoboxLayer = null;
function loadMap() {
//Prep default location
var defaultLocation = new Microsoft.Maps.Location(53.6880, -2.6646);
//Prep Map Options
var mapOptions = {
//credentials: 'KEY_REMOVED',
center: defaultLocation,
mapTypeId: Microsoft.Maps.MapTypeId.road,
zoom: 7,
enableClickableLogo: false,
enableSearchLogo: false
}
//Initialise the primary map control
map = new Microsoft.Maps.Map(document.getElementById('BobElliotMap'), mapOptions);
//Add data layer
dataLayer = new Microsoft.Maps.EntityCollection();
map.entities.push(dataLayer);
// Add infobox layer
infoboxLayer = new Microsoft.Maps.EntityCollection();
map.entities.push(infoboxLayer);
//Prep InfoBox & add to infobox layer
var infoboxOptions = {
width: 300,
height: 200,
visible: false,
offset: new Microsoft.Maps.Point(0, 20)
};
infobox = new Microsoft.Maps.Infobox(new Microsoft.Maps.Location(0, 0), infoboxOptions);
infoboxLayer.push(infobox);
//Add Data to the map
DrawPins();
setTimeout(function() {
//Initial zoom for testing zoomMap function
var pushpin = dataLayer.get(0);
var indx = dataLayer.indexOf(pushpin);
zoomMap(indx, pushpin.getLocation().latitude, pushpin.getLocation().longitude);
},500);
}
function displayInfobox(e) {
if ( this.target.id && this.target.id.indexOf("pin") != -1 ) {
alert("click event fired on pushpin");
infobox.setOptions({
title: this.target.Title,
description: this.target.Description,
visible: true,
offset: new Microsoft.Maps.Point(0, 25)
});
infobox.setLocation(this.target.getLocation());
//A buffer limit to use to specify the infobox must be away from the edges of the map.
var buffer = 30;
var infoboxOffset = infobox.getOffset();
var infoboxAnchor = infobox.getAnchor();
var infoboxLocation = map.tryLocationToPixel(this.target.getLocation(), Microsoft.Maps.PixelReference.control);
var dx = infoboxLocation.x + infoboxOffset.x - infoboxAnchor.x;
var dy = infoboxLocation.y - 25 - infoboxAnchor.y;
if (dy < buffer) { //Infobox overlaps with top of map.
//#### Offset in opposite direction.
dy *= -1;
//#### add buffer from the top edge of the map.
dy += buffer;
} else {
//#### If dy is greater than zero than it does not overlap.
dy = 0;
}
if (dx < buffer) { //Check to see if overlapping with left side of map.
//#### Offset in opposite direction.
dx *= -1;
//#### add a buffer from the left edge of the map.
dx += buffer;
} else { //Check to see if overlapping with right side of map.
dx = map.getWidth() - infoboxLocation.x + infoboxAnchor.x - infobox.getWidth();
//#### If dx is greater than zero then it does not overlap.
if (dx > buffer) {
dx = 0;
} else {
//#### add a buffer from the right edge of the map.
dx -= buffer;
}
}
//#### Adjust the map so infobox is in view
if (dx != 0 || dy != 0) {
map.setView({
centerOffset: new Microsoft.Maps.Point(dx, dy),
center: map.getCenter()
});
}
}
}
