Leaflet.draw mapping:如何在没有工具栏的情况下启动绘图功能? [英] Leaflet.draw mapping: How to initiate the draw function without toolbar?
问题描述
对于使用传单或leaflet.draw插件的任何人:
For anyone experienced with leaflet or leaflet.draw plugin:
我想在不使用 leaflet.draw工具栏的情况下开始绘制多边形
。我已经设法找到允许编辑的属性,而不使用工具栏( layer.editing.enable();
)通过在线搜索(它不在主文档中)。我似乎无法找到如何在没有工具栏按钮的情况下开始绘制多边形。任何帮助将不胜感激!
I want to initiate drawing a polygon without using the toolbar from leaflet.draw
. I've managed to find the property that allows editing without using the toolbar (layer.editing.enable();
) by searching online (it's not in the main documentation). I can't seem to find how to begin drawing a polygon without the toolbar button. Any help would be much appreciated!
谢谢:)
推荐答案
这个简单的代码适合我:
This simple code works for me:
new L.Draw.Polyline(map, drawControl.options.polyline).enable();
只需将其放入自定义按钮的onclick处理程序(或任何您想要的位置)。
Just put it into the onclick handler of your custom button (or wherever you want).
变量 map
和 drawControl
是对传单地图的引用,绘制控件。
The variables map
and drawControl
are references to your leaflet map and draw control.
潜入源代码(leaflet.draw-src.js),您可以找到绘制其他元素以及编辑或删除它们的函数。 / p>
Diving into the source code (leaflet.draw-src.js) you can find the functions to draw the other elements and to edit or delete them.
new L.Draw.Polygon(map, drawControl.options.polygon).enable()
new L.Draw.Rectangle(map, drawControl.options.rectangle).enable()
new L.Draw.Circle(map, drawControl.options.circle).enable()
new L.Draw.Marker(map, drawControl.options.marker).enable()
new L.EditToolbar.Edit(map, {
featureGroup: drawControl.options.featureGroup,
selectedPathOptions: drawControl.options.edit.selectedPathOptions
})
new L.EditToolbar.Delete(map, {
featureGroup: drawControl.options.featureGroup
})
我希望这对你也有用。
编辑:
L.EditToolbar.Edit
和 L.EditToolbar.Delete
类公开以下有用的方法:
The L.EditToolbar.Edit
and L.EditToolbar.Delete
classes expose the following useful methods:
- enable():开始编辑/删除模式
- disable():返回标准模式
- save():保存更改(触发绘制:编辑/绘制:删除事件)
- revertLayers():撤消更改
- enable(): to start edit/delete mode
- disable(): to return to standard mode
- save(): to save changes (it fires draw:edited / draw:deleted events)
- revertLayers(): to undo changes
