Morning all,
I have searched throughout the web for this and cannot even find a breadcrumb to what I am looking for.
If possible css3 only if not jQuery will do.
1) I want the whole page to smoothly fade in onload
2) When clicked on a nav link to another page I want the whole page to smoothly fade out and then fade in the new page. (separate html files, not using a single page design).
Need a cross browser friendly clean and simple code on this one.
Much appreciated.
You should use something like
FindImage.css({ "opacity": "0.1" }).animate({ "opacity": "1" },
"slow");
inside onload function and
FindImage.css({ "opacity": "1" }).animate({ "opacity": "0.1" },
"slow");
inside the callback function of click function of nav button

I cannot seem to get Chrome to pop up an "alert" page. The alert page has code in it, so it can't really be a DIV or I would just do it that way. It worked for many years, but likely do to a Chrome update it will no longer function. Still works fine in IE11, though.
The following code is used to pop up an "alert" page when there is an alert that is queried from a Database. It has always worked until recently (15 years and running)
CODE:
ClientScript.RegisterStartupScript(GetType(Page), "Alarm", "<script language='javascript'>window.showModalDialog('Alarm.aspx?ID=" & AlarmID & "', null, 'dialogWidth=460px;dialogHeight=310px;status=no;resizable=yes');document.frmA.submit();</script>")
I've tried a few things like windows.open and creating a hidden button on the asp.net page and then using the click event. Nothing works. I do not see a blocked popup in Chrome and I have even went into settings and did the following:
Set Safe Browsing to "No Protection"
Set allow pop-ups and redirects on the server name (http://servername and http://localhost)
As noted, near all browsers quite much have clamped down on popup windows. this makes things more difficult for web developers.
There are two good approaches. one I don't fancy at all is using bootstrap dialogs, but they tend to "sort of work all on their own" kind of deal based on class settings for divs etc. - really hard to debug.
Since near all sites these days include jQuery for your js code, then I quite much hands down recommend you introduce jquery.UI. It has a whole slew of nice things such as date pickers etc. But it also has a rather nice dialog pop option. They just work, and when you code them up? They follow "normal" like code approaches.
it not quite clear if your message/dialog pops after say a button click (and post back), and the at the end of that process, you need/want some dialog message to display. But all in all, I would high recommend jQuery.UI for this dialog/message that you need.
jQuery.UI in most cases expects the content you want to "display/pop" exists in a simple div in the current existing page. However, it also works VERY well if you supply the dialog another existing web page. The only REAL big issue to keep in mind? That dialog page you pop cannot handle multiple post-backs. (so, some buttons, or ONE post back in that dialog is fine - but you ONLY get the ONE post-back.
So, if that page display allows some input, or some interaction and ONLY requires ONE post-back, then jQuery.UI is again great. If that pop page requires several buttons and several post-backs, then you are in for a world of pain and hurt - jQuery.UI dialogs (like most) cannot survive or handle multiple postbacks. Any post-back means the dialog closes (collapses). So in those cases, you have to adopt ajax calls (web methods) if you need/have/want that page to have more then one active post-back button or event.
So, you could have/place a script in even your master page, and little function code stub that your register script can call.
Or, I suppose you could inject the whole script, but the script would look like this:
So, the pop page actualy is SHOVED into a div. So we have a div that "holds" the page.
The jQuery.UI code script then looks like this:
<div id="poppagearea">
</div>
<script>
function showpage() {
var mydiv = $('#poppagearea');
mydiv.dialog({
autoOpen: false, modal: true, title: 'My cool other page', width: '30%',
position: { my: 'top', at: 'top+150' },
buttons: {
'ok': function () {
mydiv.dialog('close');
alert('user click ok');
},
'cancel': function () {
mydiv.dialog('close');
alert('user click cancel');
}
}
});
mydiv.load('Default.aspx');
// Open the dialog
mydiv.dialog('open');
}
So, in above, we loaded "default.aspx" into that dialog and thus displayed it on the page.
So, I would consider jQuery.UI - but it does mean adopting a new js library into your existing project.
The pop page does gray out the full page, and you do get a title bar, and your own ok, cancel button. The above thus looks like this:
So, it does a great job - but as noted, that page can only have one post-back, and it can't be a general working aspx page with lots of buttons and post backs - but it will render and display rather well.
This is a different problem from a similar question about 'reload'. This use case has to use 'withReplaceState' to handle back button reloading.
I've found the FlowRouter documentation for FlowRouter.withReplaceState(fn), but I've been unable to find specific code examples and can't get it working.
My problem is with Isotope, a plugin that moves elements around when window is resized. User sometimes visits Isotope page, goes to another page, re-sizes window, then presses "back" button to return to Isotope page. Page has to reload to re-trigger the Isotope layout correctly for the new window size.
This is my route. How would I use FlowRouter.withReplaceState() to ensure that user who clicks back button is not seeing the cached page?
FlowRouter.route( '/work', {
action: function() {
BlazeLayout.render( 'body-static', {
content: 'work',
});
},
});
On this page I am making I have a button at the bottom of the page, which has to get wider and then move up when clicked. After the button has reached its new place, new content should load.
I have found a lot about CSS transitions an animations on hover, but I want to use this as a page transition.
How do I get this transition to happen before loading the new page??
I would love to do this with as little JS as possible..
Thanx Y'all!
Based on what you asked:
This delays the page load until the transition is complete (the setTimeout just need to be set to whatever the duration of the CSS transition is).
$('.link').click(function () {
$(this).addClass('clicked');
setTimeout( function() {
window.location.href = "url for page goes here";
}, 500);//set 500 to whatever timeout you want
});
See pen example: (http://cdpn.io/vyuch)
BUT
This is not a good idea... If CSS transitions aren't available, it will just look like a terrible link and confuse users. If they are, it is still slow and frustrating.
If you want the content to load on the same page, you need to use AJAX. To help with this, some more information would be helpful...
i have a page which is basically just a big unordered list - sort of navigation really - and its in a nasty frame (nothing i can do about that at the mo.. but i digress)
i need to reload this page/frame as items are added/removed/reordered
but i would really like it to do it via an update panel, so it doesnt (visually) have to reload the page.
unfortunately when i do drop it all in an update panel when it reloads, it doesnt re-run the jquery tree script to restyle etc itself
even if i put the jquery bit inside the update panel itself..
is there any function/event .. something that i can use to retrigger the treeview functionality?
at the mo its just in a
$(document).ready(function() {
$("ul.nav").treeview({ animated: "medium" });
});
what i really need it to do (if this is yet unclear) is to when the update panel has finished 'loading' for it to re-treeview itself
something like
$(document).hasbeenreloadedviaupdatepanel(function(){
$("ul.nav").treeview({ animated: "medium" });
});
dotn really want to have to generate it from xml using the jstree thing, which i am vaguely familiar with..
any ideas?
thanks

Take a look at this SO Question:
jQuery $(document).ready and UpdatePanels?
I'm building a photo gallery in ASP.NET. The user can browse thumbnails along the left and select one, which brings a preview-sized version into the right pane of the page.
I'd like to fade between the images, so that the current one fades out and the next one fades in. I'm using jQuery to fade the preview image in after it is loaded, which works great. Unfortunately, I can't get the fadeOut script to run before the click event posts the page back to the server. The thumbnails are ASP.NET ImageButtons, which means they're <input> tags.
Is there a way to get the postback to delay just long enough for the image to fade out? I've seen some tricks with the form onSubmit and setTimeout() but that would affect all the links and buttons on the page. I want to delay postback for the thumbnails only.
TIA
EDIT: Based on my research, and trying the suggestions below, it may be possible to delay the postback to accomplish this but it's not the best approach on several levels. To get a clean fade transition between images, in the future I would not do any posting back at all. I would use jQuery exclusively for the fadeout, load, fadein.
Try adding a return false to your function that handles the fadein/out... It should prevent the page postback from occurring...
$('#<%= this.aspbutton.ClientId%>').click(function(){
$('#myDiv').fadeout("slow");
return false;
});
I'm not sure what you are getting on the PostBack where you would want to fade out an image and then fade one in. Have you considered using AJAX for that? You could even have the thumbnail image contain the necessary information within the image tags for the larger image.
Take a look at the jQuery Lightbox plugin. I have implemented this plugin and modified the .JS a bit to allow for viewing a higher resolution photo in addition to the web view. Check it out here.
$('#<%= this.aspbutton.ClientId%>').click(function(){
var $btn = $(this);
$('#myDiv').fadeout("slow", function() {
$btn.unbind('click').click();
});
return false;
});
Here's the solution I used:
Since I AM using MS AJAX with an UpdatePanel, I can use the client-side AJAX event handler.
Sys.WebForms.PageRequestManager.getInstance().add_beginRequest(fadeOut);
function fadeOut() {
if ($('.mainImage').length > 0) {
$('.mainImage').fadeOut('normal');
}
}
This gives me the exact behavior I wanted- any time the user navigates between thumbnails, the image fades out, loads, then the new one fades in.
HOWEVER...
This is still not ideal, as there is a pause between fades while the page posts back. It will work for now but in the long run it would be better to use jQuery to set the preview image rather than the thumbnails posting back as ImageButtons.
