問題描述

對(duì)于任何使用過傳單或傳單.draw 插件的人:

For anyone experienced with leaflet or leaflet.draw plugin:

我想在不使用 leaflet.draw 的工具欄的情況下開始繪制多邊形.我已經(jīng)設(shè)法通過在線搜索(不在主文檔中)找到允許在不使用工具欄(layer.editing.enable();)的情況下進(jìn)行編輯的屬性.如果沒有工具欄按鈕，我似乎無法找到如何開始繪制多邊形.任何幫助將不勝感激！

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!

謝謝你:)

推薦答案

這個(gè)簡單的代碼對(duì)我有用:

This simple code works for me:

new L.Draw.Polyline(map, drawControl.options.polyline).enable();

只需將其放入自定義按鈕的 onclick 處理程序(或任何您想要的位置).

Just put it into the onclick handler of your custom button (or wherever you want).

變量 map 和 drawControl 是對(duì)您的傳單地圖和繪圖控件的引用.

The variables map and drawControl are references to your leaflet map and draw control.

深入研究源代碼 (leaflet.draw-src.js)，您可以找到繪制其他元素以及編輯或刪除它們的函數(shù).

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
            })

我希望這對(duì)你也有用.

L.EditToolbar.Edit 和 L.EditToolbar.Delete 類公開了以下有用的方法:

The L.EditToolbar.Edit and L.EditToolbar.Delete classes expose the following useful methods:

• enable():啟動(dòng)編輯/刪除模式
• disable():返回標(biāo)準(zhǔn)模式
• save():保存更改(觸發(fā) draw:edited/draw:deleted 事件)
• revertLayers():撤消更改
