jquery fullcalendar hide certain hours - jquery-ui

I want to use jquery fullcalendar but I want to hide certain hours.
I want to show the calendar from 8.00am->11.00am and from 16:00pm->19:00pm
So the hours between 11:00am and 16:00pm must be 'hidden'.
I don't see an option to do this :
How can I force this ?
thx in advance

You don't want to modify fullcalendar source because you want to be up to date with official branch.
Then the only way is to hide appropriate rows (hours) after fullcalendar initialization with javascript:
//hide rows with unused hours. Class names can be found in html source of
//rendered fullcalendar (fc-slotxx)
for(var i=0; i<gapshours.length; i++)
{
var gapclass = '.' + gapsclasses[i];
$(gapclass).hide()
}
//display hours for clipped borders
for(var i=0; i<sethourhours.length; i++)
{
var hourclass = '.' + sethourclasses[i] + ' th'
$(hourclass).text(sethourhours[i]);
}
After that you must remember of clipping and moving events' periods just for view purposes.

It would be very helpful to see your code; here's my best guess.
In your fullCalendar initialization code, I would use an event generating function (see event generating function)
events: function(start,end,callback){
//get your data from wherever you're getting it
var events = some_ajax_method(start, end);
//filter it down to the times you want to show
events = $.map(events, function(event){
if (event meets time criteria)
return event
else
return null;
});
callback(events);
}

Can we have a single cell as Datepicker or a dropdown?

Am using AngularJS UI-Grid. Have a constant grid with 6 columns and 4 rows. In this grid i have a specific requirement where only one cell is a date picker, one cell is a dropdown, and few cells are number only. I know that for the entire column this can be applied. Is there a way to apply this for a particular cells individually?
Any sample would be of great help.
Thanks in advance.
one option is to use a template that decides what kind of cell its going to be in relation to some row-entity-property.
I created a Plunkr showcasing such a scenario.
The setup consists of a cellTemplate:
cellTemplate: "<button ng-if=\"!row.entity.datepicker\" ng-click=\"grid.appScope.delete(row)\">DELETE ROW</button><input type=\"date\" ng-if=\"row.entity.datepicker\">"
And for this example I created a datepicker:true/false property in my row-data.
for(var i = 0; i < 3; i++) {
editor.mySeasons.push({myDate: new Date(new Date().getTime() + Math.random().toFixed(12) * 100000000000), datepicker: false});
}
editor.mySeasons.push({myDate: new Date(new Date().getTime() + Math.random().toFixed(12) * 100000000000), datepicker: true});
Hope that helps.

Google Maps and ASP .NET MVC - Center the map at a marker

I'm building a page with a Google MAP that has a side bar with dynamically created divs linked to positions of markers in the map.
I'm using ASP.NET MVC with JQuery and Google Maps API v3.
Here is a look of it.
This page is loaded in a splash window and is generated dynamically.
In the background page the user types a state or city in an input field and in my controller action I search for all people that are located in that area and return a JSON.
I get the JSON and populate the map with markers and then I make the list of divs in the side bar.
I'd like to add a function to those divs that when they are clicked the map will center at the marker.
I came up with an idea for this solution which I could not finish.
I added class="clickable" and the attributes "Lat" and "Lng" with the values equal to the ones in the markers they are related to, and I tried to get their click event with JQuery and then set the map center with its Lat and Lng like this:
$(".clickable div").click(function(){
$('map_canvas').panTo($(this).attr('lat'), $(this).attr('lng'));
}
I had 2 problems with this approach.
- First, I didn't know how to get the map with JQuery.
I found 2 ways using like $('map_canvas').gMap but it didn't work. Tried a couple more things that I've found here in Stackoverflow but also didn't work.
Second - The JQuery would not catch the event click from the DIVs.
I tested on Google Chrome console the JQuery code and It worked but then my code would not trigger the click.
I tried something like $(".clickable div").click(function(){ alert("test"); } on Google Chrome and it worked, but in my script it did not.
I also tried to add listeners using addDomListener in my code but couldn't get around that either.
Could anyone please give me a light what would be a good way to do this without having to recreate the map when a div is clicked.
I also don't like the idea of adding Lat and Lng attributes to the divs, I don't know if that would work in any browser or if its good practice. I'm just out of solutions to this.
Here is the code I'm using. (I removed some of it to make it shorter and easier to read)
$(document).ready(function () {
//Google Maps API V3 - Prepares the ajaxForm options.
var options = {
beforeSubmit: showRequestPesquisaAdvogados,
success: showResponsePesquisaAdvogados,
type: 'post',
resetForm: false
};
$('#form-pesquisaAdvogado').ajaxForm(options);
//$(".clickable").click(function () { alert($(this).attr('lat')) });
});
function showRequestPesquisaAdvogados(formData, jqForm, options) {
$("#modal-processing-background").show(); //Shows processing splash window
}
function showResponsePesquisaAdvogados(responseText, statusText, xhr, $form) {
$("#modal-processing-background").hide();
//Hide processing window
loadSplashWindow();
CreateMap(responseText);
CreateSideBar(responseText);
}
}
function CreateMap(json) {
var mapOptions = {
center: new google.maps.LatLng(json[0].Endereco.Lat, json[0].Endereco.Lng),
zoom: 5,
mapTypeId: google.maps.MapTypeId.ROADMAP
// marker:true
};
var infoWindow = new google.maps.InfoWindow();
var map = new google.maps.Map(document.getElementById("map-result"), mapOptions);
for (i = 0; i < json.length; i++) {
var data = json[i]
var myLatlng = new google.maps.LatLng(data.Endereco.Lat, data.Endereco.Lng);
var marker = new google.maps.Marker({
position: myLatlng,
map: map,
title: data.Endereco.Logradouro
});
(function (marker, data) {
// Attaching a click event to the current marker
google.maps.event.addListener(marker, "click", function (e) {
// Prepare the infoWindows content.
var contentString = //my content;
infoWindow.setContent(contentString);
infoWindow.open(map, marker);
});
//here I tried to add the listener to the div.
google.maps.event.addDomListener($(".clickable")[i], 'click',
function () {
map.panTo(new google.maps.LatLng($(this).attr('lat'),
$(this).attr('lng')));
});
})(marker, data);
}
}
function CreateSideBar(json) {
$(".sideBarConteiner").empty();
for (i = 0; i < json.length; i++) {
var contentString =
"<div class='clickable' lat='" + data.Endereco.Lat +
"' lng='" + data.Endereco.Lng + "' >" +
//...div's content here
"</div>";
$(".sideBarConteiner").append(contentString);
}
}
If you have any suggestions to make the code better or better practices, since I have only 3 months of experience with programming I might be going in the wrong direction without knowing, so please, feel free to change something if you think it'd be a better way.
I know my post is a bit lenghty, I just wanted to make it clear.
Thank you for your support in advance.
Regards,
Cesar.
I've found a way to do this by creating a global variable in javascript and keeping the map information in order to call it again later.
To to this I just added a var "map" right at the top of the .
<script type="text/javascript">
$.ajaxSetup({ cache: false }); //Forces IE to renew the cash for ajax.
var zoom = 8;
var mapOptions, map;
And then call a method to pan to the right point.
I added the properties Lat and Lng to the div and then pass the div in the javascript function and get the attributes from it.
function CreateSideBar(json) {
$(".sideBarConteiner").empty();
for (i = 0; i < json.length; i++) {
var contentString =
"<div class='clickable' data-lat='" + data.Endereco.Lat +
"' data-lng='" + data.Endereco.Lng + "' onclick='MarkerFocus(this)'>" +
//...div's content here
"</div>";
$(".sideBarConteiner").append(contentString);
}
}
And in my function:
function MarkerFocus(obj) {
var myLatlng =
new google.maps.LatLng($(obj).attr('data-lat'), $(obj).attr('data-lng'));
map.panTo(myLatlng);
}
It worked for me. I hope it helps you too.
Thanks to all for the help and support.

Select a date in UIDatePicker by UIAutomation?

I found that I can't do this by UIAPickerWheel.selectValue(), any idea?
you can pass your value in picker like this:
Picker.wheels()[1].selectValue(Your_Value);
in wheels()[1], [1] is your wheel number.
I have had difficulty using the UIAPickerWheel selectValue function on a picker with date month and day, as shown on the first (leftmost, zero index) wheel from the image below. The only solution that has worked for me, not optimal, is to tap some specified number of times above (below) the current selected value. The following code will tap above the selected value to decrement the date daysAgo times.
var datePicker = this.popupWindow().pickers()[0];
for (var i = 0; i < daysAgo; ++i) {
datePicker.wheels()[0].tapWithOptions({tapOffset:{x:0.81, y:0.30}});
this.target().delay(.4);
}

jQuery UI sortable drag initiation is slow when container has hidden items

I have an unordered 'source' list that can contain up to around 1,000 list items. I want to be able to drag the items from the source list into a connected 'destination' list. I have everything working great until my source list gets filtered. I'm using the jquery quicksearch plugin to filter (search) my source list. The filter is accomplished by setting 'display:none;' on items that don't match the search.
When 1..n items in my source list are hidden, the drag operation is not fluid when initiated. Meaning, I click on the item I want to drag, move my mouse around the screen, but the item I'm dragging does not appear under my cursor until about a full second after I've initiated the drag.
For diagnosis, I've slimmed down my use case to just one list that I want to sort. I've completely eliminated the use of quicksearch by just hard coding half of my list items as hidden. I'm still able to reproduce the 'non-fluid' behavior. My example is here:
http://pastebin.com/g0mVE6sc
If I remove the overflow style from the list in my example, the performance is a little better, but still slower than I'd hope to see.
Does anyone have any suggestions for me before I start considering other options?
Thanks in advance.
As you can see on this jsferf example, calculating outerWidth()/outerHeight() (this is what the plugin does - see below) for hidden elements (with display none) is terribly slower than for visible elements, wether it is achieved by a style attribute or a class.
The only way I have found to bypass this and still achieve the same result is to set the height for the elements to hide to zero, instead of working with the display property, whether using the style atttibute or a class:
<li style="height: 0;">b</li>
<li class="hidden">b</li>
.hidden { height: 0 }
DEMO (with class) - DEMO (with style attr)
What's happenning with sortable when dragging an element ?
When starting dragging, the plugin refreshes the list of all items and recalculates positions of all elements. The plugin actually gets outerWidth and outerHeight:
_mouseStart: function(event, overrideHandle, noActivation) {
...
//We only need to call refreshPositions, because the refreshItems call has been moved to mouseCapture
this.refreshPositions();
...
}
refreshPositions: function(fast) {
...
for (var i = this.items.length - 1; i >= 0; i--) {
var item = this.items[i];
...
if (!fast) {
item.width = t.outerWidth();
item.height = t.outerHeight();
}
var p = t.offset();
item.left = p.left;
item.top = p.top;
};
...
return this;
},​
If you still want to use display:none, this is a simple fix to the jQuery UI source specified in Didier's answer:
if (!fast) {
if(item.item.css('display') === 'none') {
item.width = 0;
item.height = 0;
}
else {
item.width = t.outerWidth();
item.height = t.outerHeight();
}
}
This is my very first post on stackoverflow, so do let me know if I messed something up.
I was also having a similar problem, but with hidden drop containers instead of sortable items. Here is my solution applying Jordan's answer to both sortable items and their containers and simply replacing the relvent method.
$.ui.sortable.prototype.refreshPositions = function(fast) {
//This has to be redone because due to the item being moved out/into the offsetParent, the offsetParent's position will change
if(this.offsetParent && this.helper) {
this.offset.parent = this._getParentOffset();
}
for (var i = this.items.length - 1; i >= 0; i--){
var item = this.items[i];
//We ignore calculating positions of all connected containers when we're not over them
if(item.instance != this.currentContainer && this.currentContainer && item.item[0] != this.currentItem[0])
continue;
var t = this.options.toleranceElement ? $(this.options.toleranceElement, item.item) : item.item;
if (!fast) {
/********** MODIFICATION ***********/
if(item.item.css('display') === 'none') {
item.width = 0;
item.height = 0;
} else {
item.width = t.outerWidth();
item.height = t.outerHeight();
}
/********** END MODIFICATION ***********/
}
var p = t.offset();
item.left = p.left;
item.top = p.top;
};
if(this.options.custom && this.options.custom.refreshContainers) {
this.options.custom.refreshContainers.call(this);
} else {
for (var i = this.containers.length - 1; i >= 0; i--){
/********** MODIFICATION ***********/
if (this.containers[i].element.css('display') == 'none') {
this.containers[i].containerCache.left = 0;
this.containers[i].containerCache.top = 0;
this.containers[i].containerCache.width = 0;
this.containers[i].containerCache.height = 0;
} else {
var p = this.containers[i].element.offset();
this.containers[i].containerCache.left = p.left;
this.containers[i].containerCache.top = p.top;
this.containers[i].containerCache.width = this.containers[i].element.outerWidth();
this.containers[i].containerCache.height = this.containers[i].element.outerHeight();
}
/********** END MODIFICATION ***********/
};
}
return this;
};
I came across with the same problem...
I've searched for a solution, but it seems there is no solution to the jquery problem, only some workaround...
I didn't found either a solution, just another workaround.
In my case I just created a general method to to a search in a sortable list, where on keyup, the code goes and do a find on every element in the list and was hiding it by fadeout if didn't match the value.
This was working very well, but when you have hundreds of items in a list, the of hidden gets big enough to trigger the slow effect on the drag&drop.
My solution was to reorder the list, bringing to the top the matched items..
Just remove and appendTo again...
This way I don't have problems with the hidden elements :)
Sorry this was no solution, but just another workaround..
Regards
More recently I came accross with this issue again... and found that my workaround was not the best solution anymore. Since the issue is the height... I've just create a CSS class with
.hidden {display: block; line-height:0; height: 0; overflow: hidden; padding: 0; margin: 0; }
and instead of setting the element hidden with just add this class and remove it to show/hide the element..
Regards,
AP
I got the same issue today with sortable + draggable table rows.
The solution was simple : use visibility:collapse instead of display:none and removing the jQuery hide/show function for the hidden lines did the trick. It's a lot faster now.
Hope I will help.

How to avoid JQuery UI accordion with a long table inside from scrolling to the beginning when new rows are appended?

I have a table of many rows in a JQuery UI accordion.
I dynamically append the table this way:
var resJson = JSON.parse(connector.process(JSON.stringify(reqJson)));
for ( var i in resJson.entryArrayM) {
// test if entry has already been displayed
if ($("#resultTr_" + resJson.entryArrayM[i].id) == null)
continue;
$("#resultTable > tbody:last").append(listEntry.buildEntryRow(resJson.entryArrayM[i]));
}
Firstly I check if a row of the same tr id already exists. If not, I would append to the last row of the table.
It works. But the problem is: every time a row is appended, the accordion would scroll to the first row of the table. Since the table is remarkably long, it makes users inconvenient to scroll down again and again to watch newly-added rows. So how to avoid this?
First of all, just do one append rather than appending every time through the loop:
var resJson = JSON.parse(connector.process(JSON.stringify(reqJson)));
var seen = { };
var rows = [ ];
var trId = null;
for(var i in resJson.entryArrayM) {
// test if entry has already been displayed
var trId = 'resultTr_' + resJson.entryArrayM[i].id;
if($('#' + trId).length != 0
|| seen[trId])
continue;
rows.push(listEntry.buildEntryRow(resJson.entryArrayM[i]));
seen[trId] = true;
}
$("#resultTable > tbody:last").append(rows.join(''));
Also note that I corrected your existence test, $(x) returns an empty object when x doesn't match anything, not null. Not only is this a lot more efficient but you'll only have one scroll position change to deal with.
Solving your scrolling issue is fairly simple: find out what element is scrolling, store its scrollTop before your append, and reset its scrollTop after the append:
var $el = $('#whatever-is-scrolling');
var scrollTop = $el[0].scrollTop;
$("#resultTable > tbody:last").append(rows.join('')); // As above.
$el[0].scrollTop = scrollTop;
There might be a slight visible flicker but hopefully that will be lost in the noise of altering the table.
You could also try setting the table-layout CSS property of the <table> to fixed. That will keep the table from trying to resize its width or the width of its columns and that might stop the scrolling behavior that you're seeing. The downside is that you'll have to handle the column sizing yourself. But, you could try setting table-layout:fixed immediately before your append operation to minimize the hassle.
