Reload Parent Window CRM Online Google Chrome

I have a Parent entity "A" and child entity "B". I have a subgrid on the parent form to create children. When a child is created and saved, I want the Parent form to reload. I have tried the following in javascript but it doesn't seem to work:
function ReloadParentWindow() {
var loc = window.opener.location;
window.opener.location = loc;
window.opener.location.reload();
window.parent.loacation.reload();
window.parent.opener.location.reload();
window.location.assign(window.location.href);
parent.location.reload();
window.top.location.reload();
}
ALSO tried the following:
function onLoad() {
setTimeout("refresh();", 2500);
}
function refresh() {
alert"A");
Xrm.Page.getControl("clients").addOnLoad(GridOnloadFunction);
}
var GridOnloadFunction = function () {
alert("B");
// Xrm.Page.data.refresh(true);
var Id = Xrm.Page.data.entity.getId();
Xrm.Utility.openEntityForm("esi_timelog", Id);
window.location.reload(true);
};
I am using CRM 2016 online, google chrome. Please help.

Add an event on the load of the grid in the onload of the parent form. The on load is triggered every time you add a record using the + button:
Xrm.Page.getControl('yourgrid').addOnLoad(onLoadGrd);
Then in the function, you can call a refresh of the parent form:
function onLoadGrd()
{
Xrm.Page.data.refresh()
}
This is the supported way.

Try this:
var recordcount = null;
function onLoad() {
CheckRecordCount();
}
function CheckRecordCount() {
try {
setInterval(function () {
if (Xrm.Page != null && Xrm.Page != undefined && Xrm.Page.getControl("myGrid") != null &&
Xrm.Page.getControl("myGrid") != undefined) {
var rowcount = Xrm.Page.getControl("myGrid").getGrid().getTotalRecordCount();
if (recordcount == null) {
recordcount = rowcount;
} else if (recordcount != rowcount)
Xrm.Utility.openEntityForm(Xrm.Page.data.entity.getEntityName(), Xrm.Page.data.entity.getId());
}
}, 5000);
} catch (ex) {
Xrm.Utility.alertDialog(functionName + "Error: " + (ex.message || ex.description));
}
}

Detect URL if it is already opened and throw pop-up : HTML+JS [duplicate]

I want to check with JavaScript if the user has already opened my website in another tab in their browser.
It seems I cannot do that with pagevisibility...
The only way I see is to use WebSocket based on a session cookie, and check if the client has more than one socket. But by this way, from current tab, I have to ask my server if this user has a tab opened right next to their current browser tab. It is a little far-fetched!
Maybe with localstorage?

The shorter version with localStorage and Storage listener
<script type="text/javascript">
// Broadcast that you're opening a page.
localStorage.openpages = Date.now();
var onLocalStorageEvent = function(e){
if(e.key == "openpages"){
// Listen if anybody else is opening the same page!
localStorage.page_available = Date.now();
}
if(e.key == "page_available"){
alert("One more page already open");
}
};
window.addEventListener('storage', onLocalStorageEvent, false);
</script>
Update:
Works on page crash as well.

Live demo

Using local storage I created a simple demo that should accomplish what your looking to do. Basically, it simply maintains a count of currently opened windows. When the window is closed the unload events fire and remove it from the total window count.
When you first look at it, you may think there's more going on than there really is. Most of it was a shotty attempt to add logic into who was the "main" window, and who should take over as the "main" window as you closed children. (Hence the setTimeout calls to recheck if it should be promoted to a main window) After some head scratching, I decided it would take too much time to implement and was outside the scope of this question. However, if you have two windows open (Main, and Child) and you close the Main, the child will be promoted to a main.
For the most part you should be able to get the general idea of whats going on and use it for your own implementation.
See it all in action here:
http://jsbin.com/mipanuro/1/edit
Oh yeah, to actually see it in action... Open the link in multiple windows. :)
Update:
I've made the necessary changes to have the the local storage maintain the "main" window. As you close tabs child windows can then become promoted to a main window. There are two ways to control the "main" window state through a parameter passed to the constructor of WindowStateManager. This implementation is much nicer than my previous attempt.
JavaScript:
// noprotect
var statusWindow = document.getElementById('status');
(function (win)
{
//Private variables
var _LOCALSTORAGE_KEY = 'WINDOW_VALIDATION';
var RECHECK_WINDOW_DELAY_MS = 100;
var _initialized = false;
var _isMainWindow = false;
var _unloaded = false;
var _windowArray;
var _windowId;
var _isNewWindowPromotedToMain = false;
var _onWindowUpdated;
function WindowStateManager(isNewWindowPromotedToMain, onWindowUpdated)
{
//this.resetWindows();
_onWindowUpdated = onWindowUpdated;
_isNewWindowPromotedToMain = isNewWindowPromotedToMain;
_windowId = Date.now().toString();
bindUnload();
determineWindowState.call(this);
_initialized = true;
_onWindowUpdated.call(this);
}
//Determine the state of the window
//If its a main or child window
function determineWindowState()
{
var self = this;
var _previousState = _isMainWindow;
_windowArray = localStorage.getItem(_LOCALSTORAGE_KEY);
if (_windowArray === null || _windowArray === "NaN")
{
_windowArray = [];
}
else
{
_windowArray = JSON.parse(_windowArray);
}
if (_initialized)
{
//Determine if this window should be promoted
if (_windowArray.length <= 1 ||
(_isNewWindowPromotedToMain ? _windowArray[_windowArray.length - 1] : _windowArray[0]) === _windowId)
{
_isMainWindow = true;
}
else
{
_isMainWindow = false;
}
}
else
{
if (_windowArray.length === 0)
{
_isMainWindow = true;
_windowArray[0] = _windowId;
localStorage.setItem(_LOCALSTORAGE_KEY, JSON.stringify(_windowArray));
}
else
{
_isMainWindow = false;
_windowArray.push(_windowId);
localStorage.setItem(_LOCALSTORAGE_KEY, JSON.stringify(_windowArray));
}
}
//If the window state has been updated invoke callback
if (_previousState !== _isMainWindow)
{
_onWindowUpdated.call(this);
}
//Perform a recheck of the window on a delay
setTimeout(function()
{
determineWindowState.call(self);
}, RECHECK_WINDOW_DELAY_MS);
}
//Remove the window from the global count
function removeWindow()
{
var __windowArray = JSON.parse(localStorage.getItem(_LOCALSTORAGE_KEY));
for (var i = 0, length = __windowArray.length; i < length; i++)
{
if (__windowArray[i] === _windowId)
{
__windowArray.splice(i, 1);
break;
}
}
//Update the local storage with the new array
localStorage.setItem(_LOCALSTORAGE_KEY, JSON.stringify(__windowArray));
}
//Bind unloading events
function bindUnload()
{
win.addEventListener('beforeunload', function ()
{
if (!_unloaded)
{
removeWindow();
}
});
win.addEventListener('unload', function ()
{
if (!_unloaded)
{
removeWindow();
}
});
}
WindowStateManager.prototype.isMainWindow = function ()
{
return _isMainWindow;
};
WindowStateManager.prototype.resetWindows = function ()
{
localStorage.removeItem(_LOCALSTORAGE_KEY);
};
win.WindowStateManager = WindowStateManager;
})(window);
var WindowStateManager = new WindowStateManager(false, windowUpdated);
function windowUpdated()
{
//"this" is a reference to the WindowStateManager
statusWindow.className = (this.isMainWindow() ? 'main' : 'child');
}
//Resets the count in case something goes wrong in code

(2021) You can use BroadcastChannel to communicate between tabs of the same origin.
For example, put the following at the top level of your js code, then test by opening 2 tabs:
const bc = new BroadcastChannel("my-awesome-site");
bc.onmessage = (event) => {
if (event.data === `Am I the first?`) {
bc.postMessage(`No you're not.`);
alert(`Another tab of this site just got opened`);
}
if (event.data === `No you're not.`) {
alert(`An instance of this site is already running`);
}
};
bc.postMessage(`Am I the first?`);

I know it is late, but maybe help someone
This snippet of code, will detect how many tabs are open and how many are active (visible) and if none of tabs is active, it will choose last opened tab, as active one.
This code will handle windows/tab crash too and it will refresh the count at crash.
Because localStorage is not supported on Stack Overflow currently, please test here.

DevExtreme DataGrid onRowDblClick

I want to implement an onRowDblClick event for the DevExtreme DataGrid.
I need this Event for multiple grids so I would like to implement this for the DataGrid for general.
I was thinking about overriding the onClick action and check for a double click or extend the DataGrid with an onRowDblClick Action but i have no idea how to implement this.
Please advise a way to do this functionality.
OK, finally I implemented an addRowDblClick function which looks like this:
var clickTimer, lastRowClickedId;
function addRowDblClick(id, dblClickFunc) {
$("#" + id).dxDataGrid({
onRowClick: function (e) {
//OBTAIN YOUR GRID DATA HERE
var grid = $("#" + id).dxDataGrid('instance');
var rows = grid.getSelectedRowsData();
if (clickTimer && lastRowCLickedId === e.rowIndex) {
clearTimeout(clickTimer);
clickTimer = null;
lastRowCLickedId = e.rowIndex;
//YOUR DOUBLE CLICK EVENT HERE
if (typeof dblClickFunc == 'function')
dblClickFunc();
} else {
clickTimer = setTimeout(function () { }, 250);
}
lastRowCLickedId = e.rowIndex;
}
});
}
And at the DataGrid I called an function OnContentReady where I call this function with the Id and the function I want to call when I double click.
addRowDblClick('dxDataGrid', showDetail);

I that work with this :
$("#grdMain").dxDataGrid({
....
onRowPrepared:function(event){
$(event.rowElement).on('dblclick', function(){
console.log('row dblclicked');
}).on('remove', function(){
//on remove event in jquery ui libraries or
// https://stackoverflow.com/questions/29255801/jquery-on-remove-not-working-parent-node-fire-empty
$(this).off('dblclick remove');
})
}
})

I did this and worked pretty well (I followed this answer)
var clickTimer, lastRowCLickedId;
$("#grdMain").dxDataGrid({
...
onRowClick: function (e) {
//OBTAIN YOUR GRID DATA HERE
var grid = $("#grdMain").dxDataGrid('instance');
var rows = grid.getSelectedRowsData();
if (clickTimer && lastRowCLickedId === e.rowIndex) {
clearTimeout(clickTimer);
clickTimer = null;
lastRowCLickedId = e.rowIndex;
//YOUR DOUBLE CLICK EVENT HERE
alert('double clicked!');
} else {
clickTimer = setTimeout(function () { }, 250);
}
lastRowCLickedId = e.rowIndex;
}
});

Navigating to Blacklisted URL's and Canceling Them

I need to write a Firefox extension that creates a blacklist and whitelist of URL's, and checks to make sure the user wants to navigate to them whenever the user attempts to do so. I'm doing this using a main script and a content script that I attach to every page (using PageMod); I attached a listener using jQuery to every link (with the tag "a") which executes a function using window.onbeforeunload. I have two questions:
How would I prompt/ask the user if they actually did want to go to the site?
How would I stop the browser from navigating to the site if the user decided not to?
Right now my code passes messages between the two scripts in order to accomplish my goal; as far as I can tell, I can only use "document" in the content script, and save the blacklist/whitelist in the main script. I'm using simple-storage to save my lists, and the port module to pass messages between the scripts.
For question 1, I've attempted using confirm(message) to get a positive/negative response from the user, but the popup either doesn't show up or shows up for a split second then gets automatically answered with a negative response. When I look in my console's error messages, I see a "prompt aborted by user" error.
For question 2, I've already tried using event.preventDefault() by passing the click event to the function (this worked, I think). Is there a better way to do this? I've seen people using window.location = "", et cetera to do this.
Anyways, the code is below:
MAIN.JS
var ss = require("sdk/simple-storage");
exports.main = function() {
if (!ss.storage.blacklist) {
ss.storage.blacklist = [];}
if (!ss.storage.whitelist) {
ss.storage.whitelist = [];}
var data = require("sdk/self").data;
var pageMod = require("sdk/page-mod");

function whiteCNTD(str) {
for (var index = 0; index < ss.storage.whitelist.length; index++) {
if (ss.storage.whitelist[index] == str) {
return index;
}
}
return -1;
}
function blackCNTD(str) {
for (var index = 0; index < ss.storage.blacklist.length; index++) {
if (ss.storage.blacklist[index] == str) {
return index;
}
}
return -1;
}
function checkLists(URL) {
if (whiteCNTD(URL) == -1) {
if (blackCNTD(URL) != -1) {
var bool = false;
worker.port.emit("navq", "Do you want to go to this link and add it to the whitelist?");
worker.port.on("yes", function() {
bool = true;
});
worker.port.on("no", function() {
bool = false;
});
if (bool == true) {
ss.storage.blacklist.splice(index, 1);
ss.storage.whitelist.push(URL);
return true;
}
else {
return false;
}
}
else {
var bool = false;
worker.port.emit("safeq", "Is this a safe site?");
worker.port.on("yes", function() {
bool = true;
});
worker.port.on("no", function() {
bool = false;
});
if (bool == true) {
ss.storage.whitelist.push(URL);
return true;
}
else {
ss.storage.blacklist.push(URL);
return false;
}
}
}
return true;
}
worker.port.on("newURL", function(URL) {
var s = "";
s = URL;
if (checkLists(s)) {
worker.port.emit("good", s);
} else if (!checkLists(s)) {
worker.port.emit("bad", s);
}
});
}
});
}

Run JS when screen width is this

I have this js that I want to only run when the screen size is 800 or below, as it enables swiping. Please help I cant figure out away.
var snapper = new Snap({
element: document.getElementById('content')
});
and the Snap is linked by
Thanks for any help.
EDIT:
<script>
$(function() {
var SmartMenu = $('#SmartMenu');
MainMenu = $('.MainMenu');
PortfolioMenu = $('#Portfolio');
PortfolioSubMenu = $('.subMenu');
SmartMenuOpen = $('#SmartMenuOpen');
wrapperHeader = $('.wrapperHeader-Top');
if(window.innerWidth <= 800) {
var snapper = new Snap({
element: document.getElementById('W')
});
}
$(SmartMenu).on('click', function(a) {
if( snapper.state().state=="left" ){
snapper.close();
} else {
snapper.open('left');
}
});
</script>

if(window.innerWidth <= 800) {
// Your code here
}
That should do the trick the first time.
EDIT 1:
If you want it to change whenever the browser is resized
window.onresize = function(event) {
if(window.innerWidth <= 800) {
// Your code here
}
}
But do make sure that the code you include will work correctly if called multiple times when the browser is resized.
EDIT 2 With access to jQuery: #2 to support Snap API and to support init
var snapper;
function initSnapper() {
if($(window).innerWidth() <= 800) {
if(snapper === undefined) {
snapper = new Snap({
element: document.getElementById('W')
});
}
else {
snapper.enable();
}
}
else if(snapper !== undefined) {
snapper.disable();
}
}
$(window).resize(initSnapper);
initSnapper();
This will initialize snapper when the page loads and will call initSnapper when the page is resized.
And you will want to check if snapper exists before checking the state like
if( snapper && snapper.state().state=="left" ){
// snapper code
}
