Adding global function for Kendo UI Window - javascript

I am new to Kendo Window and I'm planning to declare window.resize() function as a global jquery function for all of the Kendo Windows in the pages. How can I declare it?
I've added this code below on a .js file and referenced it in _Layout.cshtml but it doesn't work:
$(window).resize(function() {
$(".k-window").kendoWindow().center();
});
When Individually used, I am using this set of code:
var modal = $("#mdlWindow").kendoWindow({
visible: false,
resizable: true,
modal: true,
content: "../Position/Info,
width: "50%",
height: "50%",
maxWidth: 500,
maxHeight: 600,
minWidth: 300,
minHeight: 400,
top: 0,
bottom: 0,
left: 0,
right: 0,
iframe: true
}).data("kendoWindow");
modal.center().open();
$(window).resize(function() {
modal.center();
});
Any suggestions are accepted. If there is a way to do it in css I will try it.

Firstly Kendo Window is a specific Kendo UI widget in wherein widget element does not have k-window class but k-window-content. Class k-window is adding to element container.
Secondly to get Kendo Window instance you shoult use .data('kendoWindow') method instead of .kendoWindow().
And finally if you would have more than one window open you have to iterate for all of them to perform an action individually.
Therefore your code centering all Kendo windows on window.resize() event should looks like:
$(window).resize(function() {
var windows = $(".k-window-content");
windows.each(function(i,v){
$(v).data("kendoWindow").center();
});
});
Here is Kendo UI Dojo example: http://dojo.telerik.com/OjuwU

jQuery UI Dialog default options

I'm using jQuery UI Dialog from Drupal 8 core (jQuery UI Dialog 1.11.4) to show node in modal, but default options doesn't suits me and I need to change them.
To show node (node id 12 in this example) in modal I'm using this from Drupal:
<a class="use-ajax" data-dialog-type="modal" href="/node/12">SHOW NODE</a>
I tried to change defaults like this:
$.extend($.ui.dialog.prototype.options, {
modal: true,
width: '100%',
height: '100%',
fluid: true,
resizable: false,
closeText: Drupal.t('Close it'),
hide: 'fadeOut',
show: 'fadeIn'
});
but I'm got empty modal with options I defined.
How I can just change these options and make it work?
You can add options to Dialog using "data-dialog-options" attribute.
For example:
<a class="use-ajax" data-dialog-type="modal" data-dialog-options='{"width":"100%", "height":"100%", "fluid":"true", "resizable":"false", "hide":"fadeOut", "show":"fadeIn"}' href="/node/12">SHOW NODE</a>

How to determine where the current visible vertical location inside a jquery dialog is?

I have a case where I am using a jquery ui dialog and I have any html table in the dialog where the dialog is fixed height:
$("#modalDialogContainer").dialog({
resizable: false,
height: 700,
autoOpen: false,
width: 1050,
modal: true,
I call an AJAX query from a button click and I want to use jquery UI blockUI plugin to show a "loading" message. Something like this:
$("#myTableInsideDialog").block({
css: {
top: '200px',
bottom: "",
left: ''
},
centerY: false, baseZ: 2000, message: $("#SavingMessage")
});
The issue I have is that the content in the dialog is longer than the height of the dialog
and I given the dialog is FIXED height so that causes the dialog to have a vertical scroll bar.
Having the scroll bar is fine (that's actually what I want) but the knock on effect is that
because of that depending if the user has scrolled down or not, the blockUI message is not centered (or even visible on the screen) vertically.
Question: Is there anyway I can detect what is visible areas inside a dialog that has a vertical scroll bar to vertically align the block message properly?
Above as you can see its hard coded to be 200px from the top so it works great if the user hasn't scrolled down but you can't see the message if the user has scrolled down the whole way
In short, if i am at the top of the scroll, then i would have this:
$("#myTableInsideDialog").block({
css: {
top: '200px',
bottom: "",
left: ''
},
centerY: false, baseZ: 2000, message: $("#SavingMessage")
});
if i am at the bottom of the scroll, then i would want this:
$("#myTableInsideDialog").block({
css: {
top: '',
bottom: "200px",
left: ''
},
centerY: false, baseZ: 2000, message: $("#SavingMessage")
});
I wouldn't alternate between top AND bottom properties:
For a window sized 1000px, top:800 == bottom:200
The important question, is how you can find out your scroll distance from the top. For that lets use a function:
function calcTopLocal() {
var s = $('#modalDialogContainer').scrollTop() + 'px';
return s;
}
Now, to apply it to your block:
$("#myTableInsideDialog").block({
css: {
top: calcTopLocal()
},
centerY: false, baseZ: 2000, message: $("#SavingMessage")
});
This can be refactored many ways. The significant detail is using scrollTop() and applying styling.
response to MKaama:
My proposed answer has no loops, no timers, and no suggestions of repeated action. There is no
Repeatedly calling a js function just to keep the position fixed is an overkill, a waste of CPU
If you want to add an loading message when the ajax is requesting the data, you can append a <div> on the dialog containing the message you want to display. Then you can apply a relative position to the dialog and an absolute position to the <div> and with margin:auto the div remains in the center of dialog always, even if you scroll the dialog.
jsFiddle demo
$("#modalDialogContainer").dialog({
resizable: true,
height: 300,
autoOpen: true,
width: 300,
modal: true,
buttons: {
'call ajax': function(){
// insert the loading div to the dialog
$(this).parent().append("<div class='loading' />");
$.ajax({
type: 'json',
url: 'jsonRequest.php',
complete: function(){
// remove the loading div
$('.loading').remove();
},
success: function(){
//do what you want
}
});
}
}
});
the CSS file should be something like this
#modalDialogContainer{
position: relative;
}
#myTableInsideDialog{
height: 1000px;
width: 100%;
}
.loading{
position: absolute;
top: 0px;
bottom: 0px;
left: 0px;
right: 0px;
margin: auto;
...
}
there is a useful plugin that can tell if an element is visile on screen or not ( scrolled to ) , you may simply use it , the function returns true for visible areas on screen :
Here is a quick demo:
http://opensource.teamdf.com/visible/examples/demo-basic.html
Here is the source page :
http://www.teamdf.com/web/194/jquery-element-onscreen-visibility
usage as simple as:
$('#element').visible()
Use
$('#modalDialogContainer').scrollTop()
to find the amount of user's scroll.
You can then show your message with
{ top: $('#modalDialogContainer').scrollTop()+'px' }
And it will always be visible for them, and appear at the top of what they are looking at :)
Why bother with the height of the content at all?
I mean, isn't an easier solution to the problem possible by putting a "BlockUI" on the JQuery Dialog. Since you have a fixed height there, your block UI would most certainly be fixed as well. There is no way the scroll can now affect your message.
A crude example is hosted here in fiddle. It gives you both experiences so you can see how it behaves.
For example, you can put the block UI on the following class.
var container = ".ui-dialog";
$(container).block({
message: '<h1>Processing</h1>'
});
$.ajax({
url: "/echo/json/",
data: {
json: {},
delay: 5
}
}).done(function() {
console.log("Done with ajax");
$(container).unblock();
});

jQuery dialog position when scrolling down

I'm using this javascript/jQuery to open a dialog, however when I scroll down on the page and open another window after closing the first one, the window will open at my selection position, plus the position I scrolled down. When I try to move it around, it will keep jumping down, causing a very annoying result.
function showDialog(url) {
dialogFrame = $('<iframe style="width:100% !important;" frameborder="0" id="Dialog" src="' + url + '" />').dialog({
autoOpen: true,
height: 500,
width: 1000,
title: 'myWindow',
resizable: false,
modal: true,
position: {
my: "center",
at: "center",
of: window
}
});
}
How can I prevent this behavior? It's probably the position : { } but what should it be?
I had the same issues with a jQuery UI dialog when the body had the CSS property position:relative;. You might want to check if that is the case.
In my case I could not remove the position:relative; so I decided to override the top value and use a fixed positioning:
$(".dialogFrame").dialog({
// ...
open: function(event, ui) {
$(event.target).parent().css('position', 'fixed');
$(event.target).parent().css('top', '20px');
}
// ...
});
The script could be optimized by calculating the effective center of the screen.

How do I hide the outline in popup window

I created popup/modal window in JS, and I need to hide the outline map container. For init map I used this js code
self.mapDialogOptions = {
autoOpen: false,
modal: true,
draggable: false,
resizable: false,
height: 450,
width: 1050,
title: '',
dialogClass: '',
open: function () {
$(this).find('#map-close').on('click', function () {
$('#map-container').dialog('close');
self.isMapDialogVisible(false);
});
}
};
If I click on the popup (map) container appears outline
see screenshot
In your css file add:
#map-container {
border-style: none;
border-width: 0;
}
When you open a jquery poup its content is moved to the body, that why your popup become so large.
So after you opened the popup, you can move its content back to the original container.
Or you can adjust the map container paddings.

jquery dialog: drag dialog at any point

Is there a trick to make a jquery dialog be draggable at any point? (i mean not only in the title bar)
As opposed to a sortable item, dialog items doesn't have that functionality (I'm not sure why). If needed, you might be able to do something like this:
$(document).ready(function() {
var
// Create dialog
dialog = $('div')
.dialog({ title: "I'm a dialog" })
.css({cursor: 'move'}),
// Get the options manually
options = dialog
.data("dialog")
.uiDialog
.data('draggable')
.options;
// Finally, extend the draggable modal box's
// options and remove any restrictions
$.extend(options, {cancel: '', handle: ''});
});
​
See a working example here: http://jsfiddle.net/gMP2d/
$("#div_id")
.dialog({
position: [3,442],
width: 300,
height: 90
})
.css({cursor: 'move'})
.parent()
.draggable({cancel:'',handle:''});
