Polygon Creation/Edition does not work

Open malishahi opened this issue 6 years ago • 7 comments

  • [ ] I'm reporting a bug, not asking for help
  • [ ] I've looked at the documentation to make sure the behaviour is documented and expected
  • [ ] I'm sure this is a Leaflet Draw code issue, not an issue with my own code nor with the framework I'm using (Cordova, Ionic, Angular, React…)
  • [ ] I've searched through the issues to make sure it's not yet reported

I have the following code to draw a polygon, but in my console I face several errors, and after drawing the first polygon, the next polygon drawing is not possible. Also, when I want to edit the first polygon, the edit buttons don't work. ERRRORs in the console are as the following:

How to reproduce

  • Leaflet version I'm using: "leaflet": "^1.3.1",
  • Leaflet Draw version I'm using: "leaflet-draw": "^1.0.2",
  • Browser (with version) I'm using: Chrome
  • OS/Platform (with version) I'm using: Linux Ubuntu
  • step 1
  • step 2

What behaviour I'm expecting and which behaviour I'm seeing

I expect to see the functionalities to work properly, not being blocked.

Minimal example reproducing the issue

Here is the code:

    L.tileLayer('http://{s}.tile.osm.org/{z}/{x}/{y}.png', {

    // FeatureGroup is to store editable layers
    // Edit Toolbar
    let drawnItems = new L.FeatureGroup();
    map.addLayer(drawnItems);

    let drawControl = new L.Control.Draw({
        //draw: false,
        draw: {

I think this is duplicated of https://github.com/Leaflet/Leaflet.draw/issues/804. I have been through this myself. Basically, every version from 0.4.12 up is broken. Use 0.4.12 and the problem should go away. The proper fix is already on master branch, but there has been no release with it yet.

aqueiros avatar Jul 19 '18 08:07 aqueiros

thanks for the note. And which leaflet version should I use? Currently I have "leaflet": "^1.3.1".

malishahi avatar Jul 19 '18 09:07 malishahi

I am using leaflet 1.3.1 with leaflet-draw 0.4.12 without problems so far. There is a devDependecy for leaflet >=0.7.0 < 1.1 but assuming you don't want to develop leaflet-draw itself, you should be fine (theoretically).

Hi malishahi,

I'm having this error:

zone-evergreen.js:172 Uncaught ReferenceError: type is not defined at Object.readableArea (leaflet.draw.js:9) at NewClass._getMeasurementString (leaflet.draw.js:8) at NewClass._getTooltipText (leaflet.draw.js:8) at NewClass._updateTooltip (leaflet.draw.js:8) at NewClass._onMouseMove (leaflet.draw.js:8) at NewClass.fire (leaflet-src.js:593) at NewClass._fireDOMEvent (leaflet-src.js:4452) at NewClass._handleDOMEvent (leaflet-src.js:4409) at HTMLDivElement.handler (leaflet-src.js:2679) at ZoneDelegate.invokeTask (zone-evergreen.js:391)

I think that is similar to your issue, it happened when I added the showarea = true option, any idea?

thanks! pedro

leaflet: ^1.6.0 leaflet-draw: ^1.0.4

Try to downgrade leaflet up to 1.2.0, this worked for me

FedericoAndreoli avatar Jun 25 '20 08:06 FedericoAndreoli

The issue is comming from here : https://github.com/Leaflet/Leaflet.draw/blob/d5dd11781c2e07f9e719308e504fe579000edf54/src/ext/GeometryUtil.js#L73

And most probably you are using javascript with 'strict mode' (undeclared variable assignment).

And this comment provides a workaround by declaring a global type with

window.type = true;
