I added a layer group to my map:
L.layerGroup([marker1, marker2]).addTo(map);
before however, i tried doing:
var myLayer = L.layerGroup([marker1, marker2]);
but then I could never get it to add to the map
I want to remove the layergroup later on I've tried
//map.removeLayer(LevelOneMarkers);
//L.layerGroup([marker1, marker2]).removeLayer([marker1, marker2]);
map.removeLayer([marker1, marker2]);
but non of those seem to work. am I missing something? I'm trying to follow
http://leafletjs.com/examples/layers-control.html
You were mostly there.
To create a series of markers and add it to a layerGroup and add that to the map:
var marker1 = new L.marker([51.5, -0.09]);
var marker2 = new L.marker([52, -0]);
var markers = L.layerGroup([marker1, marker2]);
map.addLayer(markers);
To remove that layerGroup from the map:
map.removeLayer(markers); //this takes the name of the layerGroup as the argument

Bug fix so that removeLayer works on LayerGroups
JSFiddle: Here's a working JSFiddle. Notice how it doesn't show anything because it removes the layerGroup AFTER adding it. Comment out the removeLayer line to see the markers.

I have three columns, two with divs and the central one with an svg. I made a method that calculate the top() of each paragraph inside the divs to get the position and then draw an arrow in the svg. The problem is that when I use that method the first time I open my component, I get all zeroes, probably because the paragraph aren't really drawn (they have no coordinates) yet. I tried in mounted(), which should be the right place to do that. I use it also in updated() in case I reload my json with new data.
Am I missing something trivial?
The code I use to get the coordinates is like this:
drawLine(index1, index2) {
//var plist1 = this.$refs['p_list1'];
//var plist2 = this.$refs['p_list2'];
var plist1 = document.getElementsByClassName('p_list1');
var plist2 = document.getElementsByClassName('p_list2');
if (plist1.length == 0 && plist2.length == 0) return;
var svg = document.createElementNS('http://www.w3.org/2000/svg', 'line');
//...
//const start = this.$refs['startpos'].getBoundingClientRect().top;
const start = document.getElementById('startpos').getBoundingClientRect().top;
const r1 = plist1[index1].getBoundingClientRect();
const r2 = plist2[index2].getBoundingClientRect();
index1 and index2 comes from a loop where I get which paragraph I have to connect with an arrow (also where the nextThick is)
Here is a simple example of the issue:
https://codesandbox.io/s/bootstrap-vue-test-bcozc
Note: it's badly shown, but if you press "DO" and then switch tab, you'll see that the arrow aren't correct. If you switch tab and then press DO, it will work.
Put your calculation methods in a $nextTick function to allow parents and children to fully render.
If that does not work, as a debug step, try using a setTimeout method to delay the calculation.
After understanding that the problem was linked to how tabs are built, I tried making that specific tab lazy and it worked.
<b-tab lazy ...
I don't know how tabs are normally built, but I suppose the dom is put together without having a real coordinate system and when it's made visible, I don't have any event to read to update the svg.
I would like to perform a programmatic view transition.
Here is a code I've tried :
var v = registry.byId('myenergy-pane');
v.transitionTo("home-pane");
Here is another one
var v = registry.byId('myenergy-pane');
v.performTransition("home-pane",1,"slide",null);
None of them is working.
Thanks for your help.
The second code you provided should work, but that's considering the following facts:
The code is executed after the DOM is loaded and the views are parsed by the dojo/parser. The correct way to indicate that is by using dojo/ready, for example:
require(["dojo/ready"], function(ready) {
var v = registry.byId('myenergy-pane');
v.performTransition("home-pane", 1, "slide", null);
});
Both given IDs (myenergy-pane and home-pane) are related to a widget (not only a DOM node) and are both views (dojox/mobile/View or inheriting from).
Make sure you are loading dijit/registry and the registry module alias is actually mapped to the correct module.
I also made a JSFiddle to demonstrate that it should be working: http://jsfiddle.net/g00glen00b/3JMnC/
I just started using Leaflet and Marker Clusterer to organize the markers.
Problem #1: When an unclustered marker is clicked, no popup appears.
Problem #2: When a cluster is clicked several times, all the markers within that cluster appears, and when one of this marker is clicked, its popup appears! However, after closing the popup by clicking on the map, clicking on any of these clustered markers do not open any popups!
If I only have 3 unclustered markers, the popup works fine. However, as more markers are added, once a cluster forms, clicking on the marker within any cluster will not cause the popup to open!
Initializing markerclusterer
markers = new L.MarkerClusterGroup();
map.addLayer(markers);
All markers added to markercluster markers
A loop calls on the render function to create the marker and add it to the markerclusterer's array markers. (ignore the backbone.js code)
ListingMarkerView = Backbone.View.extend({
template: _.template( $('#tpl_ListingMarkerView').html() ),
render: function() {
// Create marker
var content = this.template( this.model.toJSON() );
var marker = new L.marker(
[this.model.get('lat'), this.model.get('lng')],
{content: content});
marker.bindPopup(content);
// Add to markerclusterer
markers.addLayer(marker);
}
});
Without markerclusterer
If I add the marker directly to map instead of the markerclusterer array markers, the popups work fine, so I guess the problem has something to do with markerclusterer.
Did I do something wrong that resulted in such behavior of the popups? All help appreciated, thanks!
From what little I know of the cluster marker group, you should do this:
var markerGroup = new L.MarkerClusterGroup();
markerGroup.on('click', function(ev) {
// Current marker is ev.layer
// Do stuff
});
To add an event handler to the cluster layer instead, do this:
markerGroup.on('clusterclick', function(ev) {
// Current cluster is ev.layer
// Child markers for this cluster are a.layer.getAllChildMarkers()
// Do stuff
});
Oh, and read the github README carefully, it's all in there...
Make sure you have the right versions of everything in your Leaflet + Clusterer stack (Js and Css). Compare against the examples in the Clusterer Github repo.
I'm a complete newbie at Dojo, and Adobe AIR, which is my target. I'm
trying to put some panes into an AccordionContainer like so:
var mainview = dijit.byId("mainview");
var rand = randomString();
var widg = gtd_create_entry_widget(rand)
air.trace(mainview);
air.trace(widg);
mainview.addChild(widg);
"mainview" is my AccordionContainer, and gtd_create_entry_widget() is:
function gtd_create_entry_widget(id) {
var entry = new dijit.layout.ContentPane();
entry.attr("id",id);
entry.attr("title","title "+id);
return entry;
}
The pane shows up in the container, with the correct id and title, and
no errors, however, if I try to add another pane, the next one shows
up too, but I get the error:
TypeError: Result of expression '_7' [undefined] is not an object.
I get the same error if I run
var mainview = dijit.byId("mainview");
mainview.destroyDescendants();
and also, only one pane is destroyed at a time, and I understand this
method should destroy all the children.
I can include full project code if required.
Thanks a lot
Garry
I'm not exactly sure if this is going to fix your problem, but you're supposed to use dijit.layout.AccordianPane (http://www.dojotoolkit.org/api/dijit/layout/AccordionPane.html) with the AccordianContainer.
What is the equivalent to removeMovieClip() in AS3?
Apparently many have the same question:
StackOverflow:
How to completely remove a movieclip in as3
Remove movie clip as3
How to remove childmovieclip and add to new parent movieclip
Others:
removeMovieClip(this) in AS3?
Destroy/Delete a Movieclip???
Remove movie clip
But none of their solutions seem to work, for me:
Im working on flash CS4 with AS3:
I have a very simple movie with a single button called click. On pressing the button, a new instance of coin is created:
this.click.addEventListener(MouseEvent.CLICK,justclick);
function justclick(e:MouseEvent){
var money=new coin
this.addChild(money)
money.x=e.stageX
money.y=e.stageY
}
It might not be the best code, but it works fine. Now, the coin MovieClip is supposed to show a small animation and remove itself. In good old AS2 I would have added:
this.removeMovieClip()
in the last frame of the animation. But this doesn't exist in AS3.
I have tried, without success:
this.parent.removeChild(this) // 'Cannot access a property or method of nullobject reference'...
this.removeMovieClip() // 'removeMovieClip is not a function'
removeMovieClip(this) //'call to possibly undefined method removeMovieClip'
unloadMovie(this)//'call to possibly undefined method removeMovieClip'
Solutions?
Thanks,
this.parent.removeChild(this);
This one should be working; it's what I use. One problem I had when I switched to AS3 is that sometimes it wouldn't be added as a child right, so you might want to check that. You also have to import flash.display via putting this at the top if you're not already:
import flash.display.*
You should also remove the event listener on it before removing it.
If your animation is ending on frame 20.
note: using 19 because flash count frames from zero(0) similar to array index.
class animatedCloud
{
public function animatedCloud(){
addFrameScript(19, frame20);
}
private function frame20(){
parent.removeChild(this);
}
}
Always ensure that those self removing movieclips can get garbage collected.
This solution wiped away all my instances from a loaded swf's library symbol:
var mc:MovieClip = new definition() as MovieClip;
addChild(mc);
mc.x = 1000 * Math.random();
mc.y = 1000 * Math.random();
mc.addFrameScript(mc.totalFrames - 1, function onLastFrame():void
{
mc.stop();
mc.parent.removeChild(mc);
mc = null;
});
public static function removeDisplayObject(displayObject:DisplayObject):void {
/* normal code
if(displayObject && displayObject.parent){
displayObject.parent.removeChild(displayObject);
}
*/
displayObject ? displayObject.parent ? displayObject.parent.removeChild(displayObject) : null : null;
}
I use, in an extra blank keyframe at the end of the MovieClip which should remove itself:
stop();
MovieClip(parent).removeChild(this);
Found it to be the proper and best solution.
