I'm in developing custom Map View component with kendo-colorpicker(kendoFlatColorPicker) to change color of markers. the root element of flatcolorpicker is child element of map view wrapper element.
<div id="map-view">
<!--some elements....-->
<div id="custom-flat-color-picker"></div>
</div>
In kendoFlatColorPicker, user can select color in hsvRect panel by dragging mouse. There is a critical issue... When Pressing mouse button and dragging mouse on FlatColorPicker panel, the map image in Map View is also dragged.
I think that this issue came from event-bubbling. So, I try to use e.stopPropagation() method in 'mousedown' event. However, it is not working.
Other ways, I also try to customize _hsvEvets method in kendo FlatColorPicker source code through widget extends like below code.
var KEYDOWN_NS = 'keydown.kendoEditor';
var bind = kendo.bind;
var FlatColorPicker = kendo.ui.FlatColorPicker;
var extendFlatColorPicker = FlatColorPicker.extend({
options: {
name: 'CustomFlatColorPicker'
},
init: function (element, options){
var self = this;
FlatColorPicker.fn.init.call(self, element, options);
},
_hsvArea: function () {
var that = this,
element = that.element,
hsvRect = element.find('.k-hsv-rectangle'),
hsvHandle = hsvRect.find('.k-draghandle').attr('tabIndex', 0);
function update(x, y) {
var offset = this.offset, dx = x - offset.left, dy = y - offset.top, rw = this.width, rh = this.height;
dx = dx < 0 ? 0 : dx > rw ? rw : dx;
dy = dy < 0 ? 0 : dy > rh ? rh : dy;
that._svChange(dx / rw, 1 - dy / rh);
}
that._hsvEvents = new kendo.UserEvents(hsvRect, {
global: true,
press: function (e) {
//this.element.get(0).dispatchEvent(new Event('mousedown'));
this.offset = kendo.getOffset(hsvRect);
this.width = hsvRect.width();
this.height = hsvRect.height();
hsvHandle.focus();
update.call(this, e.x.location, e.y.location);
},
start: function () {
hsvRect.addClass('k-dragging');
hsvHandle.focus();
},
move: function (e) {
e.preventDefault();
update.call(this, e.x.location, e.y.location);
},
end: function () {
hsvRect.removeClass('k-dragging');
}
});
that._hsvRect = hsvRect;
that._hsvHandle = hsvHandle;
// var cb = that._hsvEvents.press;
// that._hsvEvents.press = function(e){
// e.stopPropagation();
// cb.call(this);
// };
}
});
kendo.ui.plugin(extendFlatColorPicker);
When user press mouse button to drag mouse, 'press' event is occured on flat color picker, however parameter 'e' has no method stopPropagation().
How can I stop bubbling from colorpicker to map view?
I solved this issue. I found event 'pointerdown' in event listener stack that can be found in chrome dev tool. About this event, I applied e.stopPropagation().
