jQuery dialog position when scrolling down - javascript

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.

Content inside fancy box need to be responsive

I would like to create a gallery that is inside a fancy box , so firstly I downloaded all the content of the gallery and appended to the html container.
<div id="popup" style="display:none;"><div class="galleria"></div></div>
The jquery part
$("#hidden_content").instagram({
clientId: blockInstaSettings.clientId
, hash: hash
, userId: blockInstaSettings.userId
, next_url: insta_next_url
, show: 10
, image_size: image_size
, onComplete: function (photos, data) {
var album_html = "";
$.each(photos, function( index, val ) {
album_html += "<img src='" + val.images.standard_resolution.url + "' data-title='' data-description='" + val.caption.text.replace("'","’") + "' longdesc='" + val.link + "'>";
});
$(".galleria").html(album_html);
$('#block_instagram').on('click', function () {
openPop();
return false;
});
}
});
Notice that I set up the listener in the button that show the fancybox
function openPop(){
$.fancybox({
'autoScale': true,
'transitionIn': 'elastic',
'transitionOut': 'elastic',
'speedIn': 500,
'speedOut': 300,
'autoDimensions': true,
'centerOnScroll': true,
'href' : '#popup'
});
Galleria.run('.galleria', {
transition: 'fade',
popupLinks: true,
show: no,
extend: function(options) {
Galleria.get(0).$('info-link').click();
}
});
}
Attempted to call galleria.run when fancybox's afterShow event; but it is still the same.
Also for CSS, it need to be :
.galleria{
width:700px;
height:500px;
}
Otherwise ,it can not generate the gallery
How to fix that?
Reference
My site:
http://internal001.zizsoft.com/be_pure/
(When you scroll to bottom, there is a slider showing instagram photos, click on the photo and you will see the gallery)
The plugin used:
http://galleria.io/
http://fancyapps.com/fancybox/
As others mentioned in the commants all those plugins you are using are responsive already. When i visit your site if i resize the window after opening the fancybox its not resized as defined as "responsive". I thought this is what you are worrying about. You can invoke this by resize galleria on window resize event. Please refer this resize script for galleria to achieve. Thanks
Update: (Essential code blocks from the referred link)
to re-initialize the galleria while window resize.
First, set up the resize function:
function ResizeGallery() {
gWidth = $(window).width();
gHeight = $(window).height();
gWidth = gWidth - ((gWidth > 200) ? 100 : 0);
gHeight = gHeight - ((gHeight > 100) ? 50 : 0);
$("#gallerycontainer").width(gWidth);
$("#gallery").width(gWidth);
$("#gallery").height(gHeight);
// Reload theme
Galleria.loadTheme('js/galleria/themes/classic/galleria.classic.js', { show: curIdx });
}
Then bind it to the window resize event:
var TO = false;
$(window).resize(function () {
if (TO !== false)
clearTimeout(TO);
TO = setTimeout(ResizeGallery, 200); //200 is time in miliseconds
});
This will essentially re-initialize by reloading the default theme. In this example, I am using the second parameter to specify which image to show- otherwise it will display the first image. Be aware that this may cause another instance of Galleria. I believe this to be a bug, and posted on their forums. You can remove the older instances as follows:
var gcount = Galleria.get().length;
if (gcount > 1) {
Galleria.get().splice(0, gcount - 1);
}
Run it after the loadTheme method. Use settimeout to delay it, because loadTheme takes some time to complete. I use 200ms. Ugly, but I need some of the features in Galleria. Hope this helps.
every thing is responsive and works good. Elaborate your problem .
if you want your popup thumbnails appear in middle of your popup use the following code
.galleria-thumbnails {
text-align: center;
width: 100% !important;
}
.galleria-image {
display: inline-block;
float: none !important;
}
I found that using the javascript to handle that worked best for me you could have your script calculate height and then do something like this where you initialized fancybox
fitToView : true,
autoSize : true,
width : 100%,
height : 'auto',
you can play with fitToView and autoSize till you get the desired effect much like pinterest
you can do this with a simple css trick .
in the responsive media screen you have to set the css as
.tp-simpleresponsive .slotholder *, .tp-simpleresponsive img {
background-size: 100% auto !important;
}

jquery showModalDialog center moves when item clicked

I have a jquery modal window which I show with the following code
function ViewProfile(Profiles) {
var url = 'Add.aspx?DashboardView=1&CloseOnUpdate=1&ProfileID=' + Profiles
$('body').addClass('stop-scrolling');
//calculate height
var winW = $(window).width() - 50;
var winH = $(window).height() - 50;
$.showModalDialog({
url: url,
height: winH,
width: winW,
position: { my: 'center', at: 'center', of: window },
scrollable: true,
closeClass: 'ui-icon-circle-close',
onClose: enableScroll
});
}
function enableScroll()
{
$('body').removeClass('stop-scrolling');
}
I execute the code with a span onclick even like this
<span onclick='ViewProfile(4)' class='btn btn-sm btn-info'>View</span>
The span is located inside of a grid (a custom grid from Obout), when a user scrolls all the way down a window and clicks on a span, it centers the modal window perfectly, but after about a second it jumps off place. At first I thought it was the window that was jumping off place but noticed the scroll position is now off, therefore the IE/Chrome window is the one that moved, not the modal window. Has anyone experienced this? Any ideas how to fix it?

make parent page Blur when dialog window open

when i clicking a Button, i need to show a popup window , pop up window is opening , once opened , i need to do blur the back end page .
My script
function showDialogBox() {
$("#divSample").dialog({
autoOpen: false,
bgiframe: true,
Height: 500,
width: 500,
modal: false,
draggable: true,
resizable: false,
position: 'center',
show: {
effect: "fade",
duration: 1000
},
hide: {
effect: "fade",
duration: 500
}
});
$("#divSample").dialog("open");
}
Thank you
A simple solution is to change the opacity of the parent page - reduce it to, say, 0.3 when the dialog is open, return it to 1 when the dialog is closed. If you want to prevent clicks on the parent while the dialog is open, add pointer-events: none to the show function and pointer-events:auto to the hide/close function.
function showDialogBox() {
$('#parent_page').css({'opacity': 0.3, 'pointer-events': 'none'})
//rest of function
}
function hideDialogBox() {
$('#parent_page').css({'opacity': 1, 'pointer-events': 'auto'})
//rest of function
}
FIDDLE
Add this in your HTML
<div style="z-index:99" class="black_overlay1 off" id="black_overlay_loader"></div>
<div id="loader" class="off" > </div>
Add this in script(jquery)
function overlay(){
$("#loader").removeClass("off").addClass("on");
$("#black_overlay_loader").removeClass("off").addClass("on");
}
add this in your class
.black_overlay1{position: fixed;_position:absolute;top:0%;left:0%;width:100%;height: 100%;background:black;z-index:1001;-moz-opacity:0.3;opacity:.30;filter:alpha(opacity=30);
overflow: hidden}
.off{display:none}
.on{
/*empty*/
}
you can get black blur background.. then edit your css to get exact look you needed

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();
});

How to call fancybox resize function when fancybox-wrap height changes

I have need to show this gallery as http://tympanus.net/Tutorials/ResponsiveImageGallery/ in fancy box. It works fine except one design problem that is fancybox doesn't come in the center for first time as it has to download few image for first time if one open the same album second time it then show correctly in the center as all image are cached. I tried to resolve this issue with following code but it is not work
I cant give fancybox fixed width and height as images are of different dimensions
$(".fancybox-frame").fancybox({
maxWidth: 740,
maxHeight: 600,
fitToView: false,
width: '70%',
height: '70%',
autoSize: true,
closeClick: true,
hideOnOverlayClick: true,
openEffect: 'none',
closeEffect: 'none',
onComplete: function () {
$.fancybox.resize();
$.fancybox.center();
}
});
Other solution i can think of is to call fancybox.center() and $.fancybox.center(); function when fancybox wrapper with changes fancybox-wrap.
This i can help me correctly repositioning the fancybox in center.
But i am not sure how to track height change for fancybox-wrap and call the reposition the fancy box.
Fancybox V 1.3.4
Help in this regarding is appreciated.
UPDATE:
Just to give you an idea i face similar problem that is happend on this link.
http://www.picssel.com/playground/jquery/getImageAjax.html
When you click for the first time it small fancy-box and doesn't re-size when image is downloaded. In my case i have to download multiple image and it take time to display the first image in between takes default value but doent resize when first image is download.
set autoSize to false in order to set width and height for fancybox. i.e.
$(".fancybox-frame").fancybox({
maxWidth: 740,
maxHeight: 600,
fitToView: false,
autoSize: false,
width: '70%',
height: '70%',
closeClick: true,
hideOnOverlayClick: true,
openEffect: 'none',
closeEffect: 'none',
onComplete: function () {
$.fancybox.resize();
$.fancybox.center();
}
});
Hope this helps you.
Dynamic Inline Content Loading
function loadAnswer(id){
jQuery.fancybox({
'content' : jQuery("#outerFAQ"+id).html(),
/*For Auto height and width*/
'onComplete' : function(){
jQuery('#fancybox-wrap').css({height:'auto',width:'auto'});
jQuery.fancybox.resize();
jQuery.fancybox.center();
}
});
}
/*Dynamically Set the id and passing it to function*/
<a class="fancybox" href="#" onClick="loadAnswer(<?php echo $data->getId()/*Dynamic id*/ ?>);"> Demo </a>
<div id="outerFAQ<?php echo $data->getId(); ?>" style="display:none;">
<div id="ans<?php echo $data->getId();?>">
demo
</div>
<div>
Single inline content loading
jQuery( "#demo" ).click(function() {
jQuery.fancybox({
'content' : jQuery("#demoContent").html(),
onComplete: function () {
/*Static height width*/
jQuery("#fancybox-content").css({
height:'500px',
overflow:'scroll',
});
jQuery("#fancybox-wrap").css("top","10");
jQuery(".fancybox-wrap").css("position", "absolute");
}
});
<a id="demo" href="#">Click me</a>
<div style="display: none">
<div id="demoContent">
demo
</div>
</div>
if you fancybox is already open and want to resize then below code will helps you.
$.ajax({
url: 'YOUR URL',
data:'DATA WANT TO TRANSFER',
type: 'post'
dataType: "text",
success:function(result){
//PLAY WITH RESULT SET
$.fancybox.toggle();
},
error:function(request,error){
alert("Error occured : "+error);
}
});
Reference from : Resize Fancybox
Solution, I managed to make it work by resizing after delay of 3 seconds by that time first image is downloaded completely
$(".fancybox-iframe").fancybox({
width: '70%',
height: '70%',
hideOnOverlayClick: true,
centerOnScroll:true,
onComplete : function(){
// $.fancybox.resize();
// $.fancybox.center();
var resize = setTimeout(function () {
$.fancybox.center();
}, 3000)
}
});
I believe more professional approach will be check using jquery when image is downloaded completely and then call $.fancybox.center(); function
Please if this is fine or we can do it some otherway.
Did you try to use <center></center> include of your fancybox? I think so it'll work on your page. and no need to use java, cause you are just trying to use it as center.
