我有一个我不明白的问题。我有两个容器，每个容器 包含一张 map 。我的目标是能够打印它们，为此我使用了 window.print() 但是当我开始打印时没有加载图 block 布局。如果您对正在发生的事情有任何想法，请告诉我。
var map1;
var map2;
$(document).ready(function(){
map1 = L.map( 'map1', {
center: [33.960057, -6.916462],
minZoom: 2,
zoom: 14,
zoomControl: true
});
L.tileLayer("https://stamen-tiles-c.a.ssl.fastly.net/terrain-labels/{z}/{x}/{y}.png",{opacity:0.7}).addTo( map1 );
L.tileLayer("http://c.tile.stamen.com/watercolor/{z}/{x}/{y}.jpg",{opacity:0.7}).addTo( map1 );
map2 = L.map( 'map2', {
center: [33.960057, -6.916462],
minZoom: 2,
zoom: 14,
zoomControl: true
});
L.tileLayer("https://stamen-tiles-c.a.ssl.fastly.net/terrain-labels/{z}/{x}/{y}.png",{opacity:0.7}).addTo( map2 );
L.tileLayer("http://c.tile.stamen.com/watercolor/{z}/{x}/{y}.jpg",{opacity:0.7}).addTo( map2 );
map1.on("click",function (e) {
var center = map1.getCenter();
map2.flyTo(center);
});
window.print();
});

在另一个 post 中看到了这个- 有帮助吗？
“使用 Chrome 和 Safari，您可以添加 CSS 样式 -webkit-print-color-adjust: exact; 到元素以强制打印背景颜色和/或图像”
关于javascript - 打印时加载图 block 的问题，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/45879834/
