The javascript onDrop event is not executing

The javascript onDrop event is not executing when an object is dropped into a drop zone. I've tried re-writing this in at least half a dozen ways with no luck and no error message either. I was looking around for reasons that would prevent the ondrop event from executing and found:
HTML5/Canvas onDrop event isn't firing?
and
https://developer.mozilla.org/en-US/docs/Web/API/HTML_Drag_and_Drop_API/Drag_operations#droptargets
To the best of my knowledge, I've accomplished all three requirements to trigger an ondrop event. I implemented both the ondragenter and ondragover events which both contain event.preventDefault(); and return false;. I also have event.preventDefault(); in the ondrop event.
var app = angular.module('myApp', []);
app.controller('myCtrl', function($scope) {
$scope.lists = [{name: "A", list: ["A Object 1", "A Object 2", "A Object 3"]},
{name: "B", list: ["B Object 1", "B Object 2", "B Object 3"]}];
$scope.drag_index = null;
$scope.drag_obj = null;
});
var dragging = false;
function toggle_dz() {
$(".drop-it").toggle();
}
function get_gbls(cs) {
while (cs.$parent) {
cs = cs.$parent;
}
return cs;
}
app.directive('zoneIt', function(){
return {
restrict: 'A',
link: function(scope, element, attrs){
$(element).on('dragenter',function(event){
event.preventDefault();
console.log("Drag Enter!");
return false;
});
$(element).on('dragover',function(event){
event.preventDefault();
console.log("Drag Over!");
return false;
});
}
};
});
app.directive('dragIt', function(){
return {
restrict: 'A',
link: function(scope, element, attrs){
$(element).on('drag',function(event){
var scope = angular.element(event.target).scope();
get_gbls(scope).drag_index = scope.$index;
get_gbls(scope).drag_obj = scope.obj;
if (!dragging) {
toggle_dz();
dragging = true;
}
});
$(element).on('drop',function(event){
event.preventDefault();
alert("DROPPED!");
});
$(element).on('dragend',function(event){
toggle_dz();
dragging = false;
var scope = angular.element(event.target).scope();
get_gbls(scope).drag_index = null;
get_gbls(scope).drag_obj = null;
get_gbls(scope).$apply();
});
}
};
});

Here is a fiddle of my code: https://jsfiddle.net/Ashkeelun/2uLwd077/1/

So, I figured it out. The ondrop event belongs with the drop zone not the item being dragged.

var app = angular.module('myApp', []);
app.controller('myCtrl', function($scope) {
$scope.lists = [{name: "A", list: ["A Object 1", "A Object 2", "A Object 3"]},

$scope.drag_index = null;
$scope.drag_obj = null;
});
var dragging = false;
function toggle_dz() {
$(".drop-it").toggle();
}
function get_gbls(cs) {
while (cs.$parent) {
cs = cs.$parent;
}
return cs;
}
app.directive('zoneIt', function(){
return {
restrict: 'A',
link: function(scope, element, attrs){
$(element).on('dragenter',function(event){
event.preventDefault();
console.log("Drag Enter!");
return false;
});
$(element).on('dragover',function(event){

Gridstact: make widget static and type error

I am a newer for javascript and gridstack. My job is creating a dashboard based on gridstack. The most close example for my goal is demo example knockout.html. Also, I need add on several new features based on this example. Here is the problem I am facing.
I need add a dropdown menu to each widget and it is added to the template, please refer the code attached below. Now I am using a button for toggling the drop menu. Is that possible for me to use the mouse right click to show the dropdown menu?
When I added the method named toggleDropdownMenu, I am getting a type error as "TypeError: this.toggleDropdownMenu is not a function", is this function should be defined somewhere?
I want to make specified widget to be a static. I added a attr settings when create the widget like staticGrid: true but does not work. How can fix this?
For each dash board, the dropdown menu is different for each widget. How can I attach dropdown menu with different items for each widget?
Please refer the code... Thank you very much for any advices!

2 containers cancel eachother

i would like to know how i can prevent two containers from canceling. the codes are almost the same i just changed a few things it doesn't mater which one i put first but the second one is not working if i switched them around the one that i put first works but not the second one. I'm using toggle to display one at a time. I'm just going to post a small part of my code.

You are including jQuery, Knockout, and jQuery-UI each twice. That's probably not the problem, but it's not good.
You're using jQuery to control which block displays, and that's a Knockout no-no. It is Knockout's job to manipulate the DOM. Have a look at Knockout templates, or the if binding for ways of controlling what displays.

It looks like you have a typo in your toggle js for the seconddiv class. You're missing an 'n' in your jquery call for it: secoddiv. If this code is straight from the source that may be the problem.

Polymer add Html tags with properties

My Polymer element displays some properties it gets passed as attributes. The content property may contain some html tags like <br> or <p>. The problem I'm facing with, is, that Polymer doesn't add the tags to the DOM tree, instead it prints them like normal text. Is there a way to force "DOM tree adding"?
The whole element:
<link rel="import" href="paper-toolbar/paper-toolbar.html">
<link rel="import" href="iron-collapse/iron-collapse.html">
<link rel="import" href="paper-material/paper-material.html">
<dom-module id="card-element" is="auto-binding">
<style>
#contentWrapper {
padding: 10px 15px;
}
#toolbar {
--paper-toolbar-background: #607D8B;
--paper-toolbar: {
font-size: 125%;
opacity: 0.9;
};
}
.maxWidth {
width: 100%;
}
</style>
<template>
<paper-material elevation="2" class="maxWidth" id="card" animatedShadow="1">
<paper-material elevation="1" class="maxWidth">
<paper-toolbar on-click="toggleCollapse" id="toolbar" justify="justified">
<span class="title">{{convertedDate}}</span><span class="title">{{fach}}</span>
</paper-toolbar>
</paper-material>
<iron-collapse id="collapse">
<div id="contentWrapper">
<span>{{content}}</span>
</div>
</iron-collapse>
</paper-material>
</template>
<script>
Polymer({
is: "card-element",
properties: {
opened: {
type: Boolean,
value: false
},
fach: {
type: String,
value: "u-oh an Error"
},
content: {
type: String,
value: "u-oh an Error"
}
},
toggleCollapse: function() {
if(this.opened) {
this.$.collapse.hide();
this.$.card.elevation = "2";
this.opened = false;
}
else {
this.$.collapse.show();
this.$.card.elevation = "5";
this.opened = true;
}
},
ready: function() {
var date = new Date(this.datum);
this.convertedDate = date.getDate() + "." + (date.getMonth() + 1) + "." + date.getFullYear();
}
});
</script>
</dom-module>

Polymer not allowed html to prevent XSS attack
But you can do this
<dom-module id="html-echo">
<style>
:host {
display: block;
}
</style>
<template>
</template>
</dom-module>
<script>
(function () {
Polymer({
is: 'html-echo',
properties: {
html: {
type: String,
observer: '_htmlChanged'
}
},
_htmlChanged: function (neo) {
// WARNING: potential XSS vulnerability if `html` comes from an untrusted source
this.innerHTML = neo;
}
});
})();
</script>
Use like
<html-echo html="[[htmlText]]"></html-echo>

Knockoutjs: Invoking function of parent component from child component

Problem:
I'm trying to build a dashboard of widgets. Each widget will have a delete button on its header. When clicked on this button, corresponding widget have to disappear.
How I designed:
I have two knockout components.
my-widget-list:
VO will have an observableArray of widget objects.
my-widget:
VO will have details to display within the widget.
Note: For simplicity, I'm replacing the widget object with just numbers.
ko.components.register('my-widget-list', {
viewModel : function(params) {
var self = this;
self.values = ko.observableArray([10,20,30,40,50]);
self.deleteWidget = function(obj)
{
self.values.remove(obj);
}
},
template: {element: 'my-widget-list-template'}
});
ko.components.register('my-widget', {
viewModel : function(params) {
var self = this;
self.value = params.value;
},
template: {element: 'my-widget-template'}
});
ko.applyBindings({});
<script src="https://cdnjs.cloudflare.com/ajax/libs/knockout/3.2.0/knockout-min.js"></script>
<my-widget-list></my-widget-list>
<script id="my-widget-list-template" type="text/html">
<div data-bind="foreach:values">
<my-widget params="value: $data"></my-widget><br>
</div>
</script>
<script id="my-widget-template" type="text/html">
<span data-bind="text: value"></span>
<button data-bind="click: $parent.deleteWidget">Delete</button>
</script>
Now, I want to invoke my-widget-list's deleteWidget function when the button is clicked.
I have thought about
Passing the parent view model reference into the child
Passing the parent function in the params attribute of the child component as a callback
But I wish to know from experts what's the best way to achieve this.
JsFiddle Link
Thanks in advance

You can pass in the parent as a param to the child:
ko.components.register('my-widget-list', {
viewModel : function(params) {
var self = this;
self.values = ko.observableArray([10,20,30,40,50]);
self.deleteWidget = function(obj) {
self.values.remove(obj);
}
},
template: {element: 'my-widget-list-template'}
});
ko.components.register('my-widget', {
viewModel : function(params) {
var self = this;
self.value = params.value;
self.remove = function () {
params.parent.deleteWidget(self.value);
};
},
template: {element: 'my-widget-template'}
});

But I'm not sure if that is a good idea, as it needlessly couples the child to the parent.
I'd recommend implementing the "remove" button in the parent, i.e. in <my-widget-list>, this way the widget can exist without a widget-list (or in a differently structured one) while the widget-list is in control of its children.
Compare window managers: They work the same way. The window manager draws the frame and the minimize/maximize/close buttons, while the window contents is drawn by the respective child process. That logic makes sense in your scenario as well.
Alternative implementation with removeWidget control in the parent:
ko.components.register('my-widget-list', {
viewModel : function(params) {
var self = this;
self.values = ko.observableArray([10,20,30,40,50]);
self.deleteWidget = function(obj) {
self.values.remove(obj);
}
},
template: {element: 'my-widget-list-template'}
});
ko.components.register('my-widget', {
viewModel : function(params) {
var self = this;
self.value = params.value;
},
template: {element: 'my-widget-template'}
});
