My page has:
1)a parent div that contains a map (Leaflet.js) and
2)a child div that contains a resizable rectangle (Interactive.js), so that users can select an area.
The rectangle "layer" is on top of the map "layer".
html:
<div id="map">
<div class="selectBox">
</div>
</div>
javascript (for initializing the Leaflet map):
var map = L.map('map').setView([0,0], 6);
L.tileLayer('https://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png', {
maxZoom: 18
}).addTo(map);
javascript (for initializing an interactive box with Interact.js)
interact('.selectBox')
.resizable({
preserveAspectRatio: false,
edges: { left: true, right: true, bottom: true, top: true }
})
.on('resizemove', function (event) {
var target = event.target,
x = (parseFloat(target.getAttribute('data-x')) || 0),
y = (parseFloat(target.getAttribute('data-y')) || 0);
// update the element's style
target.style.width = event.rect.width + 'px';
target.style.height = event.rect.height + 'px';
target.style.webkitTransform = target.style.transform =
'translate(' + x + 'px,' + y + 'px)';
target.setAttribute('data-x', x);
target.setAttribute('data-y', y);
target.textContent = Math.round(event.rect.width) + '?' + Math.round(event.rect.height);
});
The problem is that when the user resizes the interactive rectangle by dragging one of its borders, the map behind also moves. From what I can understand, this is because both Leaflet and Interact catch the onclick event.
I tried:
.on('resizemove', function (event) {
(...)
event.stopPropagation()
event.stopImmediatePropagation()
(...)
}
but none of them worked.
Is there any solution so that the map doesn't move when the user resizes the rectangle?
Thank you!
OK, I figured it out.. I post an answer, in case someone has the same problem:
The following Leaflet methods (that I was unaware of their existance):
map.dragging.disable()
map.dragging.enable()
...combined with the following Interact events:
resizestart
resizeend
...give the solution:
.on('resizestart', function (event) {
map.dragging.disable();
})
.on('resizeend', function (event) {
map.dragging.enable();
})
