动态更改传单中多边形的颜色? [英] Dynamically change the color of a polygon in leaflet?

问题描述

对于熟悉 Leaflet 的人，您知道动态更改多边形颜色的方法吗?例如，以这样定义的圆为例:

For anyone who is familiar with Leaflet, do you know a way to dynamically change a polygon's color? For example, take a circle defined like this:

window.circle = L.circle([51.508, -0.11], 500, {
color: 'red',
fillColor: '#ffffff',
    fillOpacity: 0.5
}).addTo(map);

然后，在用户单击界面上某处的按钮后(例如)，我想像这样更改圆圈的颜色:

Then later, after a user clicks a button somewhere on an interface (for example), I want to change the color of the circle like this:

window.circle.options.fillColor = "#dddddd";

代码更改了 window.circle.options.fillColor 的值，但更改不会反映在地图上多边形颜色的更改中.我四处寻找，但没有找到任何东西.有什么想法吗?

The code changes the value for window.circle.options.fillColor, but the change is not reflected by a change to the color of the polygon on the map. I've searched around but haven't found anything. Any ideas?

谢谢.

推荐答案

L.Circle extends L.Path (http://leafletjs.com/reference.html#path)，有方法 setStyle( <Path options> object )，你可以将新样式应用为 window.circle.setStyle({fillColor: '#dddddd'});

L.Circle extends L.Path (http://leafletjs.com/reference.html#path), that have method setStyle( <Path options> object ), and you can apply new style as window.circle.setStyle({fillColor: '#dddddd'});
