I am looking at creating an event and reservation system.
I found the Stack Overflow question jQuery - Mobile date picker control which shows jquery-mobile-datebox and jQuery-Mobile-Themed-DatePicker.
I want to display a calendar where certain dates I get from the server are
available
not available
reserved
When a reserved or available date is touched, I want to show times - there can be more than one time per day. The user can then click on a time to reserve it which would hit off an Ajax request.
jQuery UI datepicker, for example, has
onSelect: function(date, inst) {
From what I can see in the above pickers, what I need is not readily available. Before I start hacking them myself:
Which one would lend itself best to what I want?
Are there perhaps better ones out there that already serve my needs?
UPDATE:
Firebug gave me
<div class="ui-datebox-griddate ui-corner-all ui-btn-up-e" data-date="25" data-theme="e">25</div>
where ui-btn-up-e can be changed from a - e.
Now I need to find out if data-theme also needs to be changed
$('.ui-datebox-griddate').click(function () {
alert($(this).attr("class"));
}
What is the nicest way to toggle through three of the classes and save the state each time?
$('.ui-datebox-griddate').toggle(
function () {
$(this).????? // change ui-btn-up-? to ui-btn-up-a
$.get(...)
},
function () {
$(this).????? // change ui-btn-up-a to ui-btn-up-b
$.get(...)
},
function () {
$(this).????? // change ui-btn-up-b to ui-btn-up-c
$.get(...)
}
);
UPDATE: NOTE: When I click, the calendar change the date, reloading the calendar completely. Perhaps I need to stop that :(
What is the nicest way to toggle through three of the classes and save the state each time?
Something like:
$('.ui-datebox-griddate').click(function (e) {
var $this = $(this);
var cycle = ["ui-btn-up-a", "ui-btn-up-b", "ui-btn-up-c"];
if (typeof $this.data("ui-btn-cycle") == "undefined" ) {
this.className = this.className.replace(/ui-btn-up-./, cycle[0]);
$this.data("ui-btn-cycle", cycle[0]);
}
for (var i=0; i<cycle.length; i++) {
if ( $this.hasClass(cycle[i]) ) {
$this.removeClass(cycle[i]).addClass(cycle[i % cycle.length]);
$this.data("ui-btn-cycle", [i % cycle.length]);
break;
}
}
$.get( ... );
e.preventDefault() // stop default click behaviour
});
This can cycle though an arbitrary amount of classes. The current state would be available through calling .data("ui-btn-cycle") on the respective element.
This is even nicer:
$('.ui-datebox-griddate')
.each(function () {
var cycle = ["ui-btn-up-a", "ui-btn-up-b", "ui-btn-up-c"];
$(this).data("ui-btn-cycle", cycle);
this.className = this.className.replace(/ui-btn-up-./, cycle[0]);
})
.click(function (e) {
var cycle = $(this).data("ui-btn-cycle");
$(this).removeClass(cycle[0]).addClass(cycle[1]);
cycle.push(cycle.shift());
e.preventDefault();
});
The current state would always be .data("ui-btn-cycle")[0] on the respective element. See it working here: http://jsfiddle.net/Tomalak/mAH4n/
Based on what J.T.Sage said I thought I would have a play with jQuery Mobile Calendar. I think I have something which could potentially be extended to fulfil your requirements. I am not sure to what extent multi-colour themeing would be possible (without extensive modifications).

UPDATE
I suppose the highDates mechanism could be bypassed completely and the individual days uniquely targeted. The plugin maintains a JavaScript Date object of the last date selected (or today if nothing has been selected) - so it should be possible to get the current month and iterate through all your matching data updating the matching days in the current month as appropriate (e.g. replacing the setColours method below with something that is data/state aware).
<script type="text/javascript">
$('#page').live('pagecreate', function(event) {
$('#mydate').bind('change', function () {
//alert($(this).val());
alert($('#mydate').data('datebox').theDate);
});
setColours();
$('#mydate').bind('datebox', function (e, pressed) {
setColours();
});
$('.ui-datebox-gridplus, .ui-datebox-gridminus').bind('vclick', function(){
// To handle changing months
setColours();
//alert($('#mydate').data('datebox').theDate);
});
function setColours(){

I want to get array of currently visible clusters and then get each point data. I create method in React and it seems that method in theme for getClusterPresentation returns all possible clusters for all map zooms. How to get clusters data? This is my code:
const dataPoints = points.map(
point => new H.clustering.DataPoint(point.lat, point.lng, undefined, point),
);
const clusteredDataProvider = new H.clustering.Provider(dataPoints, {
clusteringOptions: {
eps: 32,
minWeight: 2,
},
});
const defaultTheme = clusteredDataProvider.getTheme();
clusteredDataProvider.setTheme({
getClusterPresentation: cluster => {
const clusterMarker = defaultTheme.getClusterPresentation(cluster);
return clusterMarker;
},
getNoisePresentation: noisePoint => {},
});
const layer = new H.map.layer.ObjectLayer(clusteredDataProvider);
map.addLayer(layer);
Please check the below code related to Marker Clustering. And you check same example in our Guide
/**

* must be loaded to use the Clustering

* #param {Object[]} data Raw data that contains airports' coordinates
*/
function startClustering(map, data) {
// First we need to create an array of DataPoint objects,
// for the ClusterProvider
var dataPoints = data.map(function (item) {
return new H.clustering.DataPoint(item.latitude, item.longitude);
});
// Create a clustering provider with custom options for clusterizing the input
var clusteredDataProvider = new H.clustering.Provider(dataPoints, {
clusteringOptions: {
// Maximum radius of the neighbourhood
eps: 32,
// minimum weight of points required to form a cluster
minWeight: 2
}
});
// Create a layer tha will consume objects from our clustering provider
var clusteringLayer = new H.map.layer.ObjectLayer(clusteredDataProvider);
// To make objects from clustering provder visible,
// we need to add our layer to the map
map.addLayer(clusteringLayer);
}
/**
* Boilerplate map initialization code starts below:
*/
// Step 1: initialize communication with the platform
// In your own code, replace variable window.apikey with your own apikey
var platform = new H.service.Platform({

var defaultLayers = platform.createDefaultLayers();
// Step 2: initialize a map
var map = new H.Map(document.getElementById('map'), defaultLayers.vector.normal.map, {
center: new H.geo.Point(30.789, 33.790),
zoom: 2,

My React/Next.js app contains some code in order to use Google Optimize.
All the optimize's debug shows that the experience is rendering correctly and when previewing the a/b test, it renders correctly.
Unfortunately when setting the test live, the elements that were added to the optimize's experience are rendering twice.
Here is my _app.js code:
React.useEffect(() => {
// // Google optimize workaround
window.dataLayer = window.dataLayer || [];
window.dataLayer.push({ event: 'optimize.activate' });
setLoaded(true);
}, []);
<Head>
<title key="title">My Page </title>
<link rel="preconnect" href="/www.google-analytics.com" crossOrigin />
<link rel="dns-prefetch" href="//www.google-analytics.com"></link>
<script
dangerouslySetInnerHTML={{
__html: `
(function(i, s, o, g, r, a, m) {
i['GoogleAnalyticsObject'] = r;
i[r] = i[r] || function() {
(i[r].q = i[r].q || []).push(arguments)
}, i[r].l = 1 * new Date();
a = s.createElement(o),
m = s.getElementsByTagName(o)[0];
a.async = 1;
a.src = g;
m.parentNode.insertBefore(a, m)
})(window, document, 'script', 'https://www.google-analytics.com/analytics.js', 'ga');
ga('create', 'GA_ID_OMITTED', 'auto');
ga('require', 'OPTIMISE_ID_OMITTED', {dataLayer: 'optimize.activate'});
ga('send', 'pageview');
`,
}}
/>
<script sync src="https://www.googleoptimize.com/optimize.js?id=OPTIMISE_ID_OMITTED" />
</Head>
Note: I have added had the optimize's script async with an anti-flickering code snippet and that doesn't seem to work either.
I ended up finding the issue for anyone that looks at this. It wasn't code related. Google Optimize requires you to delete previous changes to the html when editing the variants otherwise it will publish the same code the same amount of times you clicked editing and changes were created causing the elements to duplicate.
I am generating an HTML/Javascript file from an Access365 database which plots pins on a Bing Map. Each of the pins has associated metadata about the location it is pinning which is viewed by clicking the pin. However, there can be pins which are at exactly the same location (lat and long) and only the metadata for the top pin is available.
How do I either show the combined metadata or have the pins move apart a bit say when the the user mouses over them? Does anyone know how to do that? I've gone round in circles looking at the MS documentation and can't find anything to help.
P.S. There is also a clusterLayer. If that needs removing to solve the problem that's Ok but it would be better if it could stay.

When you have clusters and you want to see individual metadate for items within the cluster there are two common approaches:
Have a popup that shows the first location metadata and buttons to step/page/tab through each item in the cluster.

I'm totally puzzled with GTM, I implemented it to my webSite to trigger some events to handle traffic, ect... It's be like 2 days I saw the following error :

Solution I found temporary!
So currently my implementation of gtag let me to have firer and trigger detected by GTM, I just set a new trigger to
History modification
and now it's firing my events assigned with this trigger at each history modification. I'm not very confortable with gtag but this enough for me (for now), I'm still annoyed because of the implementation I did. I would like to find the right implementation to clean mine.
The problem clearly come from the SSR because the window variable is become undefined (don't exist in nodeJs) to the error above appear. Still search solution to fix it...
https://github.com/vercel/next.js/discussions/14980
Thx everyone and have a good day :)
You'll want to check for the existence of the window before using window.
For example:
if (typeof window !== 'undefined') {
window.gtag("config", GA_TRACKING_ID, {
page_location: url,
});
}
Also you do not need to wrap your Google Tag Manager script in <Fragment>
Lastly, it looks like gtag is not something globally available by default. You have to set it up yourself according to this document: https://developers.google.com/analytics/devguides/collection/gtagjs
Had the same issue, i used a slightly different version than the other suggestions:
if (typeof window.gtag !== 'undefined')
In my case, I forgot to add #types/gtag.js.
For example,
npm install #types/gtag.js --save-dev
It seems you don't define the gtag in _document.tsx, try to add the script in <Head>. Also, add the script which link to gtm.
<Head>
<script
async
src={`https://www.googletagmanager.com/gtag/js?id=${GA_TRACKING_ID}`}
/>
<script
dangerouslySetInnerHTML={{
__html: `
window.dataLayer = window.dataLayer || [];
function gtag(){dataLayer.push(arguments);}
gtag('js', new Date());
gtag('config', '${GA_TRACKING_ID}', {
page_path: window.location.pathname,
});
`,
}}
/>
</Head>
In my case the problem was I used import Script from "next/script"; instead simple html script. Hope it 'll help to someone.

and here is what my index page looks like:

I've just started out with polymer and I'm not quite sure what's going on here..
Thank you in advance :)
I got what the problem is..
My custom element was referencing a different Polymer.html file.
Silly me :D
I'm using Polymer Starter Kit Yeoman generator on Windows and I had the same problem:
Error: DuplicateDefinitionError: a type with name 'dom-module' is already registered
This error is triggered in Firefox console. Chrome works fine.
The components created with the generator (example: yo polymer:el my-element) have this polymer.html import:
<link rel="import" href="..\..\bower_components/polymer/polymer.html">
The base path is described with "backslash".
In some custom polymer elements I created by myself, I imported polymer.html with:
<link rel="import" href="../../bower_components/polymer/polymer.html">
And I think this lead to a duplication of some kind. To solve the problem, I just changed all automatically created imports, using only forward slashes /.
Hope this helps someone.
