Change polyline options leaflet
提问by mike
I want to change the options assigned to a Leaflet polyline (and then render it) after building it:
我想在构建后更改分配给 Leaflet 折线的选项（然后渲染它）：
// Add polyline
var polyline = L.polyline([], {weight:weight, opacity:1, color:'gray'}).addTo(map);
// Attempts to change color
polyline.options.color = 'blue' // doesn't render
polyline.options.color('blue') // throws error
polyline({color:'blue'}) // throws error
polyline._updateStyle(polyline) // throws error: not sure how exactly this works
polyline._updateStyle() // throws error
polyline({color:blue}) // throws error
Is this possible?
这可能吗？

L.Polylineis extended from L.Pathwhich has a setStylemethod:
L.Polyline是从L.Path其中扩展了一个setStyle方法：
polyline.setStyle({
color: 'black'
});
