获取屏幕分辨率

var screenWidth = window.innerWidth || document.documentElement.clientWidth || document.body.clientWidth;
var screenHeight = window.innerHeight || document.documentElement.clientHeight || document.body.clientHeight;

console.log("当前屏幕分辨率： " + screenWidth + "x" + screenHeight);

const height = window.innerHeight || document.documentElement.clientHeight || document.body.clientHeight;
if (height >= 961) {  // 100%
    padding = 300
} else if (height >= 746) { // 125%
    padding = 100
} else { // 大于125%
    padding = 0
}
map.fitBounds(bound, {
    duration: 1000,
    padding
})

在不同的分辨率下给geojson不同的padding
