Detect background events - fullcalendar

I am using FullCalendar in my project. I used background events, rendering="background". How can I detect if user click on the background events? I try this but it doesnot work since all dates cannot be clicked.
dayClick: function (start, end, allDay, jsEvent, view,color,calEvent) {
if (calevent.rendering==="background") {
alert('Click Background Event Area');
}
else{
$('#modal1').modal('show');
}
if (start.isBefore(moment())) {
$('#calendar').fullCalendar('unselect');
return false;
}
},

Since fullCalendar doesn't expose an "click" type event on background events, the only way I can think of to do this is essentially a DIY approach. The basic idea:
Handle the "select" event
Fetch all the events currently in fullCalenar's memory, using the "clientEvents" method.
Loop through them all and check whether any of them are background events, and if so, whether they overlap with the selected time period. If they do, then that's the event that was clicked on.
I haven't tested this, but it's based on some old code I found, so hopefully you get the idea:
select: function(start, end, jsEvent, view) {
var cal = $("#calendar"); //put the ID of your calendar element here
var evts = cal.fullCalendar('clientEvents'); //get all in-memory events
var selectedEvent = null;
for (i in evts) {
if (evts[i].rendering == "background" && start.isBefore(evts[i].end) && end.isAfter(evts[i].start)) {
selectedEvent = evts[i];
}
}
}
The only flaw in this is that "select" allows selection of a time period, not just a single click, so it could be that the selection is overlapping the background event, and not wholly contained within it. You might be able to adjust the logic a little bit if that doesn't suit you - e.g. to require that both start and end are within the event's boundaries.

Clarity Datagrid column input filter losing focus on first keypress after moving to next page in paginated grid

Using a clarity datagrid version 2.3
Seeing an issue where if the user starts typing into the input field of datagrid column filter, the filter input focuses out automatically as soon as a key is pressed.
Since the datagrid is paginated and server driven, this causes the API to get fired as soon as a
key is pressed after the debounce time.
The automatic focus out of the input field cause the filter to only have a single character and the API gets triggered since the debouce is only 800.
Have looked at clarity github for any reported issues, doesn't look like its reported or anyone having similar issue.
Expected behavior should be the input focus out should not happend until the user moves the cursor away or presses enter, which is when the debounce should kickin after which the api should be called.
HTML:
<clr-datagrid
(clrDgRefresh)= refreshDataGrid($event)>
...
</clr-datagrid>
TS Component:
debouncer = new Subject<any>();
ngOnInit() {
this.debouncer.asObservable().pipe(
debounceTime(800)
).subscribe(state => {
// do something here.. like call an API to filter the grid.
})
}
refreshDataGrid(state) {
this.debouncer.next(state);
}
Any help is appreciated.
Currently I'm hacking my component, to make sure the focus is not lost on the input field until done so by the user.
refreshDataGrid(state) {
const isClrFilterInputField = document.querySelector('.datagrid-filter .clr-input');
if (isClrFilterInputField instanceof HTMLElement) {
isClrFilterInputField.focus();
}
this.debouncer.next(state);
}
This is still not a clean answer, but as far as I have searched, this seems like an issue with clarity datagrid itself, until I hear from someone with a cleaner answer.
Most likely the upgrade version might have this fixed.
Yet to check that.
Unfortunately I think we designed the datagrid to emit the changes on each filter value change with debouncing intended to be done on the app side as consumers see fit.
That said, it is possible to accomplish what you describe. I've implmented a quick and dirty guard based on events but there may be better ways. I'll add code snippets here and a link to the working stackblitz at the end.
You are on the right track with the debouncer. But we don't need to debounce with time, we only need to 'debounce' on certain events.
Instead of debouncing with time, what if we debounce with an #HostListener for clicks on the filter input? (I'll leave it as an exercise for you to implement a HostListener for the focusin event since focusin bubble's up and blur does not). To do that we need:
A Hostlistener that can hear keydown.enter event on the filter input
A guard to prevent requests
A property to store the datagrid state as user enters text
In general the code needs to:
Fetch data when component inits but not after unless directed
Keep track of state events that get emitted from the datagrid
listen to keydown.enter events (and any other events like the filter input focusout - becuase it bubbles up, unlike blur)
Check that the event was generated on a datagrid filter input
dismiss the guard
make the request
re-enlist the guard
Here is a rough attempt that does that:
export class DatagridFullDemo {
refreshGuard = true; // init to true to get first run data
debouncer = new Subject<any>(); // this is now an enter key debouncer
datagridState: ClrDatagridStateInterface; // a place to store datagrid state as it is emitted
ngOnInit() {
// subscribe to the debouncer and pass the state to the doRefresh function
this.debouncer.asObservable().subscribe(state => {
this.doRefresh(state);
});
}
// a private function that takes a datagrid state
private doRefresh(state: ClrDatagridStateInterface) {
// Guard against refreshes ad only run them when true
if (this.refreshGuard) {
this.loading = true;
const filters: { [prop: string]: any[] } = {};
console.log("refresh called");
if (state.filters) {
for (const filter of state.filters) {
const { property, value } = <{ property: string; value: string }>(
filter
);
filters[property] = [value];
}
}
this.inventory
.filter(filters)
.sort(<{ by: string; reverse: boolean }>state.sort)
.fetch(state.page.from, state.page.size)
.then((result: FetchResult) => {
this.users = result.users;
this.total = result.length;
this.loading = false;
this.selectedUser = this.users[1];
// Set the guard back to false to prevent requests
this.refreshGuard = false;
});
}
}
// Listen to keydown.enter events
#HostListener("document:keydown.enter", ["$event"]) enterKeydownHandler(
event: KeyboardEvent
) {
// Use a host listener that checks the event element parent to make sure its a datagrid filter
const eventSource: HTMLElement = event.srcElement as HTMLElement;
const parentElement = eventSource.parentElement as HTMLElement;
if (parentElement.classList.contains("datagrid-filter")) {
// tell our guard its ok to refresh
this.refreshGuard = true;
// pass the latest state to the debouncer to make the request
this.debouncer.next(this.datagridState);
}
}
refresh(state: ClrDatagridStateInterface) {
this.datagridState = state;
this.debouncer.next(state);
}
}

Select a game object and perform actions using GUI.Button (EventTrigger)

I am currently working on a strategy game and I want to preform actions using GUI.Button on game objects. I am using ray cast and mouse click to select the object however when I click on GUI.Button to take out another action the button disappears. I want to use that button to open up another GUI.Box to show some descriptions.
I know why the button is disappearing, it is because I am projecting the ray cast to my button clicks in the update function but how can I avoid this? I also know that I have to use EventTrigger however I am not familiar with javascript event trigger, I searched online but I couldn't find any helpful javascript.
Screenshots:
Here is my script:
#HideInInspector
var isCalled:int = 0;
#HideInInspector
var scWidth:int = 0;
#HideInInspector
var scHeight:int = 0;
function Start () {
scWidth = Screen.width;
scHeight = Screen.height;
}
function Update () {
if (Input.GetMouseButtonDown(0)) {
var ray : Ray = Camera.main.ScreenPointToRay (Input.mousePosition);
var hit : RaycastHit;
if (Physics.Raycast (ray, hit)) {
if (hit.collider.tag == "House") {
isCalled = 1;
} else{
isCalled = 0;
}
}
}
}
function OnGUI(){
if(isCalled==1)
GUI.Button(Rect(scWidth/2,(scHeight/2)+(scHeight/4),120,120), name);
}
}
If I understood you right, the problem is that when you click on button the raycast is fired up before button click and you select different object or no object at all and button disappears or reappears but for another object, what you need to do is check if you clicked on GUI and if yes don't project the raycast that selects the objects. Here is how you are gonna do it.
var selectedUI : GameObject = EventSystem.current.currentSelectedGameObject;
if (Input.GetMouseButtonDown(0) && selectedUI) {
var ray : Ray = Camera.main.ScreenPointToRay (Input.mousePosition);
var hit : RaycastHit;
if (Physics.Raycast (ray, hit)) {
if (hit.collider.tag == "House") {
isCalled = 1;
} else{
isCalled = 0;
}
}
}
I work in C#, so I might have done some syntax errors, but the logic is right.
There is a good trick when using legacy GUI system to avoid raycast when mouse is over GUI elements. Using tooltip to controll if you may cast your ray =)
Something like this (I also don't work with US so may I it needs some work):
var hover : String;
function OnGUI(){
if(GUI.Button (Rect (10,10,100,20), "My Button"));
hover = GUI.tooltip;
function Update () {
if(hover != "") {
// raycast logic
}
}
If you need to avoid raycast when your "popUp" window/panel is shown but you don't want a tooltip on it you may approach using a MouseOverGUI manager too.
It is just a static or singleton holding a boolean that you will set true when your mouse is over some rect that you don't want to cast rays using Rect.Contains(Event.current.mousePosition) and to false whenever it runs out of this rect.
Use this bool with or without tooltip var to allow raycast:
if(!MouseManager.MouseOverGUI) {
// raycast logic
}
Note that creating your rect on each OnGUI cycle will difficult to catch it and control the MouseOveGUI. Also it is a bad practice for performance because OnGUI runs more than once per frame so I'll suggest you to create you rects just once (recalculate it just when needed) and pass it to your GUI elements ;)
I think the easiest way is to create a GameObject(input blocker) which is not visible but have a collider. Place it in between the camera and level objects and deactivate it. When you select a GameObject using Raycast you enable that input blocker GameObject and place it around the area of selected GameObject and GUI. Then you have to ignore the selection if raycast is collided with Input Blocker. When you deselect the Gameobject then you deactivate input blocker
You should also maintain current state of the game for example:
enum State
{
NothingSelected = 0,
GameobjectSelected,
BigMenuOpen
}
State currentState;
So according to state you can define the behavior on mouse click. Like if Full screen menu is Open then raycast does not fire.

Dragging event reverts before confirm

I have a calendar with drag functionality where a user can drag events to quickly update them.
After Dragging an event I ask the user if he wants to save it and then call a UpdatEvent function.
However, before the user confirms, (just as the dialog appears) the event automatically reverts back and only return to the updated position if I confirm in the dialog.
Is there a way for the event to stay in the dragged position and then either revert back or stay in the actual one?
My eventDrop looks like this:
eventDrop: function (event, delta, revertFunc) {
if (confirm("Do you wish to save the event?")) {
UpdateEvent(event.id, event.start);
}
else {
revertFunc();
}
}
At the beginning of the Eventdrop and/or Eventresize place the following:
$('#calendar').fullCalendar('updateEvent', event);

Fullcalendar, Events filer sometimes is not working

On page I have fullcalendar, variable which determines how to display now (all events or events with filter), button for changing variable value and function which applies filter.
Variable (true - show all events, false - with filter):
var isShownWithCancelEvents = true;
Button and it's click function:
$('.fc-header-left').append('<span class="fc-button fc-button-show-with-canceled-events fc-state-default"><span class="fc-button-inner"><span id="show_without_canceled_events" class="fc-button-content">Show with filter</span><span class="fc-button-effect"><span></span></span></span>');
$(".fc-button-show-with-canceled-events").click(function() {
isShownWithCancelEvents = !isShownWithCancelEvents;
prepareEvents();
});
Function prepareEvents():
function prepareEvents(){
if (isShownWithCancelEvents) {
$('#calendar').fullCalendar('refetchEvents');
$(".fc-button-show-with-canceled-events .fc-button-content ").text("Show with filter");
}
else {
$('#calendar').fullCalendar ( 'removeEvents', filter );
$(".fc-button-show-with-canceled-events .fc-button-content ").text("Show all events");
}
}
Filter function:
function filter(event) {
return (event.ec_e_id !== null);
}
Also in fullcalendar I use option:
viewDisplay: function(view) {
prepareEvents();
},
Button is working, problem is with fullcalendar option.
Default view on page is agendaWeek. I open page and click button, variable's value changes to false, filter applies. It's OK. Then I click button "Month" and view changes to month. And I see all events. Then I click button "Week" and view changes to agendaWeek - events are filtered. I click button "Month" again - on this view events are filtered too. So, the problem is when first time changing view to another.
I open page and click button, variable's value changes to false, filter applies. It's OK. Then I navigate left or right (next or previous week), and I see all events. Then I return back, where events were filtered and see all events there.
If I add alert into fullcalendar option
viewDisplay: function(view) {
alert("something");
prepareEvents();
},
everything is OK, and filter works every time.

Is it possible to force a menu popout to trigger on click instead of mouseover?

I use a ASP.NET Menu control with Orientation=Horizontal. It is kind of irritating that the popout menus appear on mouseover, which causes it to show by accident if you move the mouse over the menu when you want to click on something right below the menu. Then the menu popout hides the element you actually wanted to click on!
Is it possible to change the functionality so that the popout requires a mouse click instead of mouseover?
Well, I found a solution myself (kind of a hack...).
This solution requires use of AJAX to capture the menu item onclick postback event, so it can be picked up client side in javascript before doing the actual postback when you click the menu item.
First, I override these functions that is defined by the Menu control
to ignore the menu popout in the mouseover event:
var activeMenuItem = null;
function Menu_HoverStatic(item) {
// Register the active item to be able to access it from AJAX
// initialize postback event
activeMenuItem = item
// Apply the style formatting on mouseover (colors etc).
// This was also called in the original Menu_HoverStatic function.
Menu_HoverRoot(item);
}
function Menu_Unhover(item) {
activeMenuItem = null; // This is the only difference to the original
var node = (item.tagName.toLowerCase() == "td") ?
item:
item.cells[0];
var nodeTable = WebForm_GetElementByTagName(node, "table");
if (nodeTable.hoverClass) {
WebForm_RemoveClassName(nodeTable, nodeTable.hoverClass);
}
node = nodeTable.rows[0].cells[0].childNodes[0];
if (node.hoverHyperLinkClass) {
WebForm_RemoveClassName(node, node.hoverHyperLinkClass);
}
Menu_Collapse(node);
}
// Then I added a renamed copy of the original `Menu_HoverStatic` function:
function Menu_ClickStatic() {
// Pick up the active menu item that is set in the
// overridden Menu_HoverStatic function.
// In the original, the item was input parameter.
var item = activeMenuItem;
// The rest is identical to the original Menu_HoverStatic.
var node = Menu_HoverRoot(item);
var data = Menu_GetData(item);
if (!data) return;
__disappearAfter = data.disappearAfter;
Menu_Expand(node, data.horizontalOffset, data.verticalOffset);
}
Then I snap up the onclick postback event in AJAX that is triggered by the menu. This must be done to cancel the onclick postback and display the menu popout instead.
// Get the Page Request Manager that provides all the .NET
var prm = Sys.WebForms.PageRequestManager.getInstance();
// Register postback event for asyncronous AJAX postbacks
if (prm) prm.add_initializeRequest(InitializePostback);
function InitializePostback(sender, args) {
var element = args.get_postBackElement();
//Check if the postback element is the menu
if (element.id == 'myMenu') {
// Name of the menu element that triggered is the postback argument
var postbackArguments = document.getElementById('__EVENTARGUMENT');
if (postbackArguments)
// Check on the menu item name to pick up only the menu items that shall
// trigger the popout (not the items that does an actual command).
if (postbackArguments.value == 'MenuTopItem1'
|| postbackArguments.value == 'MenuTopItem2'
|| postbackArguments.value == 'MenuTopItem3') {
// Abort and cancel the postback
prm.abortPostBack();
args.set_cancel(true);
Menu_ClickStatic(); // Call my own copy of the original function
return;
}
}
}
Note:
I found out the details about these functions by using the script viewer in Firebug.
The soluton provided above doesn't work in everone's case. One can also try this out, it worked in my solution-
var jq = jQuery.noConflict();
jq(document).ready(function () {
jq(document).on('click', '#ctl_id_Here', function () {
Menu_HoverStatic(this);
Menu_HoverRoot(this);
});
jq(document).on('click', '#ctl_id_Here', function () {
Menu_HoverStatic(this);
Menu_HoverRoot(this);
});
});
3 Steps:
Stop the current hovering effects:
On page load (or on ready), write following line: $('#Menu1').find('ul .level2').css('display','none');
Once you do that, it'll stop the hovering effect of that menu. But once you do that, then you would only be able to open the submenu by making it display block, so for that I wrote following lines, onclick of an image inside the menu: $('#Menu1').find('ul .level2').css('display','block');
Open the menu on click of an element: I don't think need to explain it. Just make menu display block on click of the identified element.
Close the opened menu: 2 ways to do it: First; Use property Disapperafter as below:
Second: Write below code to close it onclick of anywhere else on the screen:
$('body').click(function(evnt) {
if($(evnt.target).parents('table#menu').length == 0)
{
$('#MenuInvitePatient').find('ul .level2').css('display','none');
return;
}
else
{
return;
}
});
