Is there any way to open leaflet layer control only when clicked?
By default, it expands/collapse when on mouseover/mouseout. I want to open only on click.
You can use a bit of jQuery to get this done.
Set the 'collapsed' option to false and instead, create a button to show/hide the layer control.
btn.onclick = function() {
$('.leaflet-control-layers').toggle();
}

Stop propagation on mouse over solved it. I am using d3 here but It can be easily handled by plain javascript or by jQuery.
d3.select(".leaflet-control-layers-toggle").on("mouseover", function () {
//this will make sure that layer popup menu
//not opens when mouseover
d3.event.stopPropagation();
});

I am trying to allow a mapbox marker to be clicked on and when clicked it automatically takes you to a new link.
Is this possible?
I currently have a map of 10 locations and when loaded the zoom level shows all. When you click on a location, it zooms you into that location.
I now want it to take you through to a url on the click rather than zoom in, however I cant seem to find any documentation on how to do it.
I am aware that it can be done using a popup box which contains a url in it, but is there a way to remove the extra step.
Thank you
You can use click event on your layer to get the feature clicked and use a property of your feature to build your link :
map.on('click', 'layername', function(e) {
// Here you can access e.features[0] which is the feature cliked
// With that you can do whatever you want with your feature
});
Sébastien Bousquet's answer work when using a Symbol, but if using a Marker, you'll need to add your your own click eventlistener like https://developer.mozilla.org/en-US/docs/Web/API/Element/click_event.
marker.getElement().addEventListener('click', event => {
window.location.href = 'https://www.mapbox.com/';
});
I would like to add a custom container to Leaflet. The container would contain edit controls and would be used as a kind of properties editor in order to customize the map (marker colors, zoom level, polyline color, etc ...). The panel would be displayed when the user clicks on a "settings" button located on the map.
Is there a Leaflet plugin for this?
I also had a look at how to implement custom controls, but I am really not clear how to achieve this. In particular it seems to me that I can only use JavaScript and DOM manipulations (and no direct HTML markup) in order to create a custom control.
Could someone please help me bootstrap the control? thanks!
Edit:
So I tried to create a very simple container consisting of a single checkbox "control" as follow:
L.Control.SettingsPanel = L.Control.extend({
onAdd: function(map){
var checkbox = L.DomUtil.create('input');
checkbox.setAttribute("type", "checkbox");
checkbox.style.width = '200px';
return checkbox;
}
});
L.control.settingsPanel = function(opts){
return new L.Control.SettingsPanel(opts);
}
The sidebar v2 leaflet plugin might be what you are looking for.
I need to develop a functionality in IBM Content Navigator where after search for an item, right click it-> Properties, I need to either:
1 - add a button in properties dialog screen that will call a service and open another dialog;
2 - or extend the Save button functionality to also call a service and open another dialog;
What's quickest way to achieve that ?
Have a look # ecm.widget.dialog.EditPropertiesDialog and onSave() method. This might help you to extend save button functionality.
You can add your customized code by using aspect before/after:
(choose either depending on your functionality)
aspect.after(ecm.widget.dialog.EditPropertiesDialog.prototype,"onSave", function(event){
......
});
aspect.before(ecm.widget.dialog.EditPropertiesDialog.prototype,"onSave", function(event){
......
});
I have a requirement where i need to display side by side a source code editor and a wysiwyg editor such as tinymce . The idea is that the user should click on any element inside the wysiwg editor and the corresponding element should highlight in the source code editor.
So far i have been able to get the selected node in tinymce by using the onnodechange event
setup: function(ed) {
ed.on('NodeChange', function(e){
console.log(e.element);
});
}
but, the event doesn't fire when the editor is in readonly mode. Do you know why this is happening or can you suggest me a way to overcome this issue ?
I have found a workaround by adding the following inside setup callback
//prevent user to edit content inside tinymce
ed.on('PostRender', function(e){
ed.getBody().setAttribute('contenteditable', false);
});
ed.on('KeyPress', function(e){
e.preventDefault();
e.stopPropagation();
});
It's not perfect, but at least, it does the trick ;)
I had a similar problem, but we needed to intercept the click event, not "NodeChange".
I resolved by adding the event handler directly on the body element of the tinymce iframe and using the event target.
bodyEl.addEventListener('click', function(e) {
console.log('Hello ', e.target);
}, false)
If you need to detect selection change, you could use the 'select' event.
As we are facing GWT performance issues in a mobile app I peeked into Google Wave code since it is developed with GWT.
I thought that all the buttons there are widgets but if you look into generated HTML with firebug you see no onclick attribute set on clickable divs. I wonder how they achieve it having an element that issues click or mousedown events and seemingly neither being a widget nor injected with onclick attribute.
Being able to create such components would surely take me one step further to optimizing performance.
Thanks.
ps: wasnt google going to open source client code too. Have not been able to find it.
You don't have to put an onclick attribute on the HTML to make it have an onclick handler. This is a very simple example:
<div id="mydiv">Regular old div</div>
Then in script:
document.getElementById('mydiv').onclick = function() {
alert('hello!');
}
They wouldn't set the onclick property directly, it would have been set in the GWT code or via another Javascript library.
The GWT documentation shows how to create handlers within a GWT Java app:
public void anonClickHandlerExample() {
Button b = new Button("Click Me");
b.addClickHandler(new ClickHandler() {
public void onClick(ClickEvent event) {
// handle the click event
}
});
}
This will generate an HTML element and bind a click handler to it. However, in practice this has the same result as using document.getElementById('element').onclick() on an existing element in your page.
You can hook functions to the onclick event using JavaScript. Here's an example using jQuery:
$(document).ready(function(){
$("#div-id").click(function(){
/* Do something */
});
});
If you're interested in optimizing performance around this, you may need to investigate event delegation, depending on your situation.
A click event is generated for every DOM element within the Body. The event travels from the Body down to the element clicked (unless you are using Internet Explorer), hits the element clicked, and then bubbles back up. The event can be captured either through DOM element attributes, event handlers in the javascript, or attributes at any of the parent levels (the bubbling or capturing event triggers this).
I'd imagine they've just set it in a .js file.
Easily done with say jQuery with $(document).ready() for example.
