必应地图显示地图的左上角的北美

Bing Maps display North America top-left corner of map

本文关键字：地图 左上角 显示      更新时间：2023-09-26

我试图在地图上的左上角显示北美/加拿大。

现在使用地图选项的中心将无济于事，因为它会根据屏幕尺寸而变化。

我通过使用这样的东西进一步弄脏了垃圾：

var viewRect = Microsoft.Maps.LocationRect.fromCorners(new Microsoft.Maps.Location(-37.71859032558814, -95.2734375), // african ocean 
            new Microsoft.Maps.Location(63.704722429433225, 101.25)
        );
map.setView({ bounds: viewRect });

现在这比专注于中心要好，因为它在大屏幕的左上角显示北美，但屏幕尺寸仍然是一个问题。

有没有人知道任何其他方法允许在屏幕的左上角显示北美，而不管屏幕尺寸如何？

任何帮助/建议将不胜感激。

这是我所做的，专注于某个中心，根据不同的标准屏幕尺寸在加载过程中修改地图视图。 

function GetBestViewBasedOnScreenSize() {
var viewportWidth = document.documentElement.clientWidth, viewportHeight = document.documentElement.clientHeight;
console.log("changed the height is " + viewportHeight + " the widht is " + viewportWidth);
console.log('view 1');
if (viewportWidth > 300 && viewportWidth <= 600) {
}
else if (viewportWidth > 300 && viewportWidth <= 1000) {
    console.log('900 - 1200');
    var center = new Microsoft.Maps.Location(26.628887011185398, 27.903637500000013);
    map.setView({ center: center, zoom: 2 });
    console.log('center is ' + '26.628887011185398 27.903637500000013');
}
else if (viewportWidth > 1000 && viewportWidth <= 1200) { // most common

    var center = new Microsoft.Maps.Location(4.78563220981988, 47.58330624999998);
    map.setView({ center: center, zoom: 3 });
    console.log('center is ' + '4.78563220981988 47.58330624999998 ');
} else {
    // load world
