Our elements are color coded so when a user selects one we just want to isolate it in the views (which works as expected) BUT we don't want it to change to the selection color - where can we control this?
Use selection event to find which object has been selected, cancel the selection and isolate the selected dbId, is this the behavior you are looking for?
AutodeskNamespace("Autodesk.ADN.Viewing.Extension");
Autodesk.ADN.Viewing.Extension.Basic = function (viewer, options) {
Autodesk.Viewing.Extension.call(this, viewer, options);
var _this = this;
_this.load = function () {
console.log('LOAD')
viewer.addEventListener(
Autodesk.Viewing.AGGREGATE_SELECTION_CHANGED_EVENT, function(e) {
//console.log(e)
if(e.selections.length) {
var dbId = e.selections[0].dbIdArray[0]
viewer.select([])
viewer.isolate(dbId)
}
})
return true;
};
_this.unload = function () {
Autodesk.Viewing.theExtensionManager.unregisterExtension(
"Autodesk.ADN.Viewing.Extension.Basic");
return true;
};
};
Autodesk.ADN.Viewing.Extension.Basic.prototype =
Object.create(Autodesk.Viewing.Extension.prototype);
Autodesk.ADN.Viewing.Extension.Basic.prototype.constructor =
Autodesk.ADN.Viewing.Extension.Basic;
Autodesk.Viewing.theExtensionManager.registerExtension(
"Autodesk.ADN.Viewing.Extension.Basic",
Autodesk.ADN.Viewing.Extension.Basic);
In case you want to keep the selection just not make it blue in the UI, you can change the selection material's opacity to see-through:
viewer.impl.selectionMaterialBase.opacity = 0;
viewer.impl.selectionMaterialTop.opacity = 0;
Now when you click on an object it won't turn blue.
I have a main folder with index.html file for my html app. I have written a code in index.html of main folder to access the file (index.html) present in the sub folder as follows,
SubFile
When i click on the above link, it is not navigating to the subfile and instead the link of main folder index.html file changes to mainfolder/index.html#!/subfolder/index.html
I even tried changing the name of subfolder file but no success. What could be the problem?
I also want to navigate back to the main folder index.html from subfolder as follow,
Mainfile
But it is also not working. How can I achieve this as well?

What shall i remove from it to solve my problem?
#!/subfolder/index.html
This make me feel that you are using a single page application framework/library, like Angular or something related. So maybe your problem is not in the html but in your javascript code.
Please remove all javascript and check it will work fine then revert all js one by one and test you will find the conflict javascript resolve that conflict. it will work fine.
I need to Inject html/javascript-code into every HTML that gets loaded.
The program uses the HTML class.
I disassembled the original Flex3 files and found this.
The important? functions I modified/tested:
public function set htmlText(value:String) : void
{
_htmlText = value;
htmlTextChanged = true;
_location = null;
locationChanged = false;
invalidateProperties();
invalidateSize();
invalidateDisplayList();
dispatchEvent(new Event("htmlTextChanged"));
}
public function set location(value:String) : void
{
_location = value;
locationChanged = true;
_htmlText = null;
htmlTextChanged = false;
invalidateProperties();
invalidateSize();
invalidateDisplayList();
dispatchEvent(new Event("locationChange"));
}
I successfully changed the code of set location and managed that only http://www.example.com/ gets loaded.
However, the htmlText setter seems not to get called when the location is set using location.
This is what I have tried:
public function set htmlText(value:String) : void
{
_htmlText = "<html><h1>test</h1></html>" + value;
htmlTextChanged = true;
_location = null;
locationChanged = false;
invalidateProperties();
invalidateSize();
invalidateDisplayList();
dispatchEvent(new Event("htmlTextChanged"));
}
I need to have a look in flash.net.HTMLloader but I cannot locate the file.
I hope someone can help me and tell me where the HTML-code gets loaded from the location and where it gets rendered so I can modify it before.
Thanks in advance.
I don't know what do you want to inject to your html content, but I think that you can do it when the complete event on the HTMLLoader of your HTML component is fired, using the window object which is :
The global JavaScript object for the content loaded into the HTML control..
So you can use it ( the window object ) as in any JavaSript code.
// for the example, I took the page of your current question
var url:String = 'http://stackoverflow.com/questions/32348824/inject-html-javascript-code-into-flex-as3-html-class';
html_content.location = url;
html_content.htmlLoader.addEventListener(Event.COMPLETE, on_complete);
And
protected function on_complete(e:Event): void
{
var html_loader:HTMLLoader = html_content.htmlLoader;
var document = html_loader.window.document;
var _head = document.getElementsByTagName('head')[0];
// create a new css class
var _class = '.akmozo { background: #ff9900; color: white; padding: 2px; }';
var _style = document.createElement('style');
_style.appendChild(document.createTextNode(_class));
// create a new js function
var _js = 'function click_me(){ alert("Hello, how are you ?"); }';
var _script = document.createElement('script');
_script.appendChild(document.createTextNode(_js));
_head.appendChild(_style);
_head.appendChild(_script);
// change the page's top bar background color to green
if(document.querySelector('.topbar-wrapper'))
{
document.querySelector('.topbar-wrapper').style.backgroundColor = 'green';
}
// edit the title of your question,
// apply the new css class and call the js function
if(document.querySelector('.question-hyperlink'))
{
document.querySelector('.question-hyperlink').innerHTML += ' [ edited by <span class="akmozo" onclick="click_me()">AKMOZO</span> ]';
}
// change the SO logo to my avatar
if(document.getElementById('hlogo'))
{
document.getElementById('hlogo').style.backgroundImage = 'url(https://i.stack.imgur.com/YAKpv.png?s=50)';
document.getElementById('hlogo').style.backgroundRepeat = 'no-repeat';
}
// do some changes in your comment
if(document.querySelector('#comment-52605069'))
{
document.querySelector('#comment-52605069 .comment-copy').style.color = 'green';
document.querySelector('#comment-52605069 .comment-copy').style.fontWeight = 700;
document.querySelector('#comment-52605069 .comment-copy').style.fontSize = '24px';
document.querySelector('#comment-52605069 .comment-user').innerHTML = '<span class="akmozo">akmozo</span>';
}
}
This code will give you something like this :
Of course I tried just to give you an example of what you can do, you have to improve and adapt this code to your needs.
Hope that can help.
I'd like to be able to highlight the drop area as soon as the cursor carrying a file enters the browser window, exactly the way Gmail does it. But I can't make it work, and I feel like I'm just missing something really obvious.
I keep trying to do something like this:
this.body = $('body').get(0)
this.body.addEventListener("dragenter", this.dragenter, true)
this.body.addEventListener("dragleave", this.dragleave, true)`
But that fires the events whenever the cursor moves over and out of elements other than BODY, which makes sense, but absolutely doesn't work. I could place an element on top of everything, covering the entire window and detect on that, but that'd be a horrible way to go about it.
What am I missing?
I solved it with a timeout (not squeaky-clean, but works):
var dropTarget = $('.dropTarget'),
html = $('html'),
showDrag = false,
timeout = -1;
html.bind('dragenter', function () {
dropTarget.addClass('dragging');
showDrag = true;
});
html.bind('dragover', function(){
showDrag = true;
});
html.bind('dragleave', function (e) {
showDrag = false;
clearTimeout( timeout );
timeout = setTimeout( function(){
if( !showDrag ){ dropTarget.removeClass('dragging'); }
}, 200 );
});
My example uses jQuery, but it's not necessary. Here's a summary of what's going on:
Set a flag (showDrag) to true on dragenter and dragover of the html (or body) element.
On dragleave set the flag to false. Then set a brief timeout to check if the flag is still false.
Ideally, keep track of the timeout and clear it before setting the next one.
This way, each dragleave event gives the DOM enough time for a new dragover event to reset the flag. The real, final dragleave that we care about will see that the flag is still false.
Modified version from Rehmat (thx)
I liked this idea and instead of writing a new answer, I am updating it here itself. It can be made more precise by checking window dimensions.
var body = document.querySelector("body");
body.ondragleave = (e) => {
if (
e.clientX >= 0 && e.clientX <= body.clientWidth
&& e.clientY >= 0 && e.clientY <= body.clientHeight
) {} else {
// do something here
}
}
Old Version
Don't know it this works for all cases but in my case it worked very well
$('body').bind("dragleave", function(e) {
if (!e.originalEvent.clientX && !e.originalEvent.clientY) {
//outside body / window
}
});
Adding the events to document seemed to work? Tested with Chrome, Firefox, IE 10.
The first element that gets the event is <html>, which should be ok I think.
var dragCount = 0,
dropzone = document.getElementById('dropzone');
function dragenterDragleave(e) {
e.preventDefault();
dragCount += (e.type === "dragenter" ? 1 : -1);
if (dragCount === 1) {
dropzone.classList.add('drag-highlight');
} else if (dragCount === 0) {
dropzone.classList.remove('drag-highlight');
}
};
document.addEventListener("dragenter", dragenterDragleave);
document.addEventListener("dragleave", dragenterDragleave);
Here's another solution. I wrote it in React, but I'll explain it at the end if you want to rebuild it in plain JS. It's similar to other answers here, but perhaps slightly more refined.
import React from 'react';
import styled from '#emotion/styled';
import BodyEnd from "./BodyEnd";
const DropTarget = styled.div`
position: fixed;
top: 0;
right: 0;
bottom: 0;
left: 0;
pointer-events: none;
background-color:rgba(0,0,0,.5);
`;
function addEventListener<K extends keyof DocumentEventMap>(type: K, listener: (this: Document, ev: DocumentEventMap[K]) => any, options?: boolean | AddEventListenerOptions) {
document.addEventListener(type, listener, options);
return () => document.removeEventListener(type, listener, options);
}
function setImmediate(callback: (...args: any[]) => void, ...args: any[]) {
let cancelled = false;
Promise.resolve().then(() => cancelled || callback(...args));
return () => {
cancelled = true;
};
}
function noop(){}
function handleDragOver(ev: DragEvent) {
ev.preventDefault();
ev.dataTransfer!.dropEffect = 'copy';
}
export default class FileDrop extends React.Component {
private listeners: Array<() => void> = [];
state = {
dragging: false,
}
componentDidMount(): void {
let count = 0;
let cancelImmediate = noop;
this.listeners = [
addEventListener('dragover',handleDragOver),
addEventListener('dragenter',ev => {
ev.preventDefault();
if(count === 0) {
this.setState({dragging: true})
}
++count;
}),
addEventListener('dragleave',ev => {
ev.preventDefault();
cancelImmediate = setImmediate(() => {
--count;
if(count === 0) {
this.setState({dragging: false})
}
})
}),
addEventListener('drop',ev => {
ev.preventDefault();
cancelImmediate();
if(count > 0) {
count = 0;
this.setState({dragging: false})
}
}),
]
}
componentWillUnmount(): void {
this.listeners.forEach(f => f());
}
render() {
return this.state.dragging ? <BodyEnd><DropTarget/></BodyEnd> : null;
}
}
So, as others have observed, the dragleave event fires before the next dragenter fires, which means our counter will momentarily hit 0 as we drag files (or whatever) around the page. To prevent that, I've used setImmediate to push the event to the bottom of JavaScript's event queue.
setImmediate isn't well supported, so I wrote my own version which I like better anyway. I haven't seen anyone else implement it quite like this. I use Promise.resolve().then to move the callback to the next tick. This is faster than setImmediate(..., 0) and simpler than many of the other hacks I've seen.
Then the other "trick" I do is to clear/cancel the leave event callback when you drop a file just in case we had a callback pending -- this will prevent the counter from going into the negatives and messing everything up.
That's it. Seems to work very well in my initial testing. No delays, no flashing of my drop target.
Can get the file count too with ev.dataTransfer.items.length
#tyler's answer is the best! I have upvoted it. After spending so many hours I got that suggestion working exactly as intended.
$(document).on('dragstart dragenter dragover', function(event) {
// Only file drag-n-drops allowed, http://jsfiddle.net/guYWx/16/
if ($.inArray('Files', event.originalEvent.dataTransfer.types) > -1) {
// Needed to allow effectAllowed, dropEffect to take effect
event.stopPropagation();
// Needed to allow effectAllowed, dropEffect to take effect
event.preventDefault();
$('.dropzone').addClass('dropzone-hilight').show(); // Hilight the drop zone
dropZoneVisible= true;
// http://www.html5rocks.com/en/tutorials/dnd/basics/
// http://api.jquery.com/category/events/event-object/
event.originalEvent.dataTransfer.effectAllowed= 'none';
event.originalEvent.dataTransfer.dropEffect= 'none';
// .dropzone .message
if($(event.target).hasClass('dropzone') || $(event.target).hasClass('message')) {
event.originalEvent.dataTransfer.effectAllowed= 'copyMove';
event.originalEvent.dataTransfer.dropEffect= 'move';
}
}
}).on('drop dragleave dragend', function (event) {
dropZoneVisible= false;
clearTimeout(dropZoneTimer);
dropZoneTimer= setTimeout( function(){
if( !dropZoneVisible ) {
$('.dropzone').hide().removeClass('dropzone-hilight');
}
}, dropZoneHideDelay); // dropZoneHideDelay= 70, but anything above 50 is better
});
Your third argument to addEventListener is true, which makes the listener run during capture phase (see http://www.w3.org/TR/DOM-Level-3-Events/#event-flow for a visualization). This means that it will capture the events intended for its descendants - and for the body that means all elements on the page. In your handlers, you'll have to check if the element they're triggered for is the body itself. I'll give you my very dirty way of doing it. If anyone knows a simpler way that actually compares elements, I'd love to see it.
this.dragenter = function() {
if ($('body').not(this).length != 0) return;
... functional code ...
}
This finds the body and removes this from the set of elements found. If the set isn't empty, this wasn't the body, so we don't like this and return. If this is body, the set will be empty and the code executes.
You can try with a simple if (this == $('body').get(0)), but that will probably fail miserably.
I was having trouble with this myself and came up with a usable solution, though I'm not crazy about having to use an overlay.
Add ondragover, ondragleave and ondrop to window
Add ondragenter, ondragleave and ondrop to an overlay and a target element
If drop occurs on the window or overlay, it is ignored, whereas the target handles the drop as desired. The reason we need an overlay is because ondragleave triggers every time an element is hovered, so the overlay prevents that from happening, while the drop zone is given a higher z-index so that the files can be dropped. I am using some code snippets found in other drag and drop related questions, so I cannot take full credit. Here's the full HTML:

I see a lot of overengineered solutions out there. You should be able to achieve this by simply listening to dragenter and dragleave as your gut seemingly told you.
The tricky part is that when dragleave fires, it seems to have its toElement and fromElement inverted from what makes sense in everyday life (which kind of makes sense in logical terms since it's the inverted action of dragenter).
Bottom-line when you move the cursor from the listening element to outside that element, toElement will have the listening element and fromElement will have the outer non-listening element. In our case, fromElement will be null when we drag outside the browser.
Solution
window.addEventListener("dragleave", function(e){
if (!e.fromElement){
console.log("Dragging back to OS")
}
})
window.addEventListener("dragenter", function(e){
console.log("Dragging to browser")
})
The ondragenter is fired quite often. You can avoid using a helper variable like draggedFile. If you don't care how often your on ondragenter function is being called, you can remove that helper variable.
Solution:
let draggedFile = false;
window.ondragenter = (e) => {
if(!draggedFile) {
draggedFile = true;
console.log("dragenter");
}
}
window.ondragleave = (e) => {
if (!e.fromElement && draggedFile) {
draggedFile = false;
console.log("dragleave");
}
}
Have you noticed that there is a delay before the dropzone disappears in Gmail? My guess is that they have it disappear on a timer (~500ms) that gets reset by dragover or some such event.
The core of the problem you described is that dragleave is triggered even when you drag into a child element. I'm trying to find a way to detect this, but I don't have an elegantly clean solution yet.
really sorry to post something that is angular & underscore specific, however the way i solved the problem (HTML5 spec, works on chrome) should be easy to observe.
.directive('documentDragAndDropTrigger', function(){
return{
controller: function($scope, $document){
$scope.drag_and_drop = {};
function set_document_drag_state(state){
$scope.$apply(function(){
if(state){
$document.context.body.classList.add("drag-over");
$scope.drag_and_drop.external_dragging = true;
}
else{
$document.context.body.classList.remove("drag-over");
$scope.drag_and_drop.external_dragging = false;
}
});
}
var drag_enters = [];
function reset_drag(){
drag_enters = [];
set_document_drag_state(false);
}
function drag_enters_push(event){
var element = event.target;
drag_enters.push(element);
set_document_drag_state(true);
}
function drag_leaves_push(event){
var element = event.target;
var position_in_drag_enter = _.find(drag_enters, _.partial(_.isEqual, element));
if(!_.isUndefined(position_in_drag_enter)){
drag_enters.splice(position_in_drag_enter,1);
}
if(_.isEmpty(drag_enters)){
set_document_drag_state(false);
}
}
$document.bind("dragenter",function(event){
console.log("enter", "doc","drag", event);
drag_enters_push(event);
});
$document.bind("dragleave",function(event){
console.log("leave", "doc", "drag", event);
drag_leaves_push(event);
console.log(drag_enters.length);
});
$document.bind("drop",function(event){
reset_drag();
console.log("drop","doc", "drag",event);
});
}
};
})
I use a list to represent the elements that have triggered a drag enter event. when a drag leave event happens i find the element in the drag enter list that matches, remove it from the list, and if the resulting list is empty i know that i have dragged outside of the document/window.
I need to reset the list containing dragged over elements after a drop event occurs, or the next time I start dragging something the list will be populated with elements from the last drag and drop action.
I have only tested this on chrome so far. I made this because Firefox and chrome have different API implementations of HTML5 DND. (drag and drop).
really hope this helps some people.
When the file enters and leaves child elements it fires additional dragenter and dragleave so you need to count up and down.
var count = 0
document.addEventListener("dragenter", function() {
if (count === 0) {
setActive()
}
count++
})
document.addEventListener("dragleave", function() {
count--
if (count === 0) {
setInactive()
}
})
document.addEventListener("drop", function() {
if (count > 0) {
setInactive()
}
count = 0
})
I found out from looking at the spec that if the evt.dataTransfer.dropEffect on dragEnd match none then it's a cancelation.
I did already use that event to handle copying without affecting the clipboard. so this was good for me.
When I hit Esc then the drop effect was equal to none
window.ondragend = evt => {
if (evt.dataTransfer.dropEffect === 'none') abort
if (evt.dataTransfer.dropEffect === 'copy') copy // user holds alt on mac
if (evt.dataTransfer.dropEffect === 'move') move
}
on "dropend" event you can check the value of the document.focus() was the magic trick in my case.
