Cross browser compatibility issue for showing and hiding div - asp.net-mvc

I have MVC app.
I have written below code in the JS in Create view.
Basically on the basis of selection on drop down I show and hide the div.
Now the problem is below code works perfectly in Google chrome and Mozilla Firefox.
but now working in IE 8.
What should I do ?
$('#PaymentType').change(function(){
var ptype=document.getElementById("PaymentType").value;
if(ptype=="On Account")
{
$(".InvoiceDiv").hide();
}
else
{
$(".InvoiceDiv").show();
}
});

I am not sure what real issue is but since you are using jQuery why don't you use it for your ptype, too? With this, cross-browser issue will be minimized (if not completely avoided).
$('#PaymentType').change(function(){
var ptype = $(this).val();
...
});
Hope this helps.

If your Js files has full of references to a method called document.getelementbyid
Or order of your Js files and Css files which you import to program with < Link / > Tag ,
Reorder them and test it in IE
i think that the reason your code breaks right at the beginning of the function.

Material Select blinking on iOS

I am trying to create my website in Material Design, however I found one issue with Material Select regardless whether I use MDB (Material Design for Bootstrap) or Materialize CSS framework. Both are working fine on Windows/OSX/Android , however for some reason when I open Material Select component on my iPad and click on it, there is a blinking cursor showing from the Background of the Dropdown.
Try the following code:
input.select-dropdown {
-webkit-user-select:none;
-moz-user-select:none;
-ms-user-select:none;
-o-user-select:none;
user-select:none;
}
I had the same issue on iOS devices, I am using select dropdown from materialisecss "http://materializecss.com/forms.html".
to fix the blinking cursor issue, I used reference code from below link and slightly modified that code.
Ref Link: https://github.com/Dogfalo/materialize/issues/901 (check comment by "chi-bd commented on 17 Nov 2015")
jQuery('select').material_select();
/*--- Materialize Select dropdown blinking cursor fix for iOS devices ---*/
jQuery('select').siblings('input.select-dropdown').on('mousedown', function(e) {
if( /Android|webOS|iPhone|iPad|iPod|BlackBerry|IEMobile|Opera Mini/i.test(navigator.userAgent) ) {
if (e.clientX >= e.target.clientWidth || e.clientY >= e.target.clientHeight) {
e.preventDefault();
}
}
});
jQuery('select').material_select(); to initialize materialise select and rest code is the fix.
the only problem was this was giving problem on desktop view so added mobile detection condition
if( /Android|webOS|iPhone|iPad|iPod|BlackBerry|IEMobile|Opera Mini/i.test(navigator.userAgent) ) {
Note: Add this code in document ready $(document).ready(function() { ... });
that's it. I hope this will sort out your issue.
Regards, and have a nice day :)
There is an open issue on github, #StaticBR proposed an approach to solve "Dropdown Broken on iPhone (and Safari in general)" issue, link here.
According to #StaticBR,
"The Issue is that IO13 Safari propagate TouchEnd Events before the Click event is propagated.
So if you have a click listener within an drop down, it is not correctly triggerd, because the Dropwdown is getting closed by the TouchEnd event. After that the click event is at a different position or does not longer exist.
Removing the touch event listener solved this issue for me."
Apologies, the above code works but then it stops the scrolling for drop-down.
For now I am using below fix, but it shows the blinking cursor first and then it hides it. but still this is not the perfect solution, if anyone has better solution please post here :)
function checkDropDown(obj){
var nextObj = jQuery(obj).next();
setTimeout(function(){
if (jQuery(nextObj).is(":visible")){
jQuery("input.select-dropdown").css({
"transition" : "none",
"left" : "-999999px"
});
}else{
jQuery("input.select-dropdown").css({
"left" : 0
});
}
}, 250);
jQuery(document).ready(function(){
jQuery("input.select-dropdown").on("focus", function(){
checkDropDown(jQuery(this));
});
jQuery("input.select-dropdown").on("blur", function(){
checkDropDown(jQuery(this));
});
});

Prevent select2 from autmatically focussing its search-input when dropdown is opened

I'm looking for a way to prevent select2's search-input being automatically focussed when the select2-dropdown is opened. I know this is select2's intended default behavior - and while this is fine for desktop clients, I need to prevent this behavior for the iPad where it triggers the iPads software keyboard, which is not what we want as a default.
I've searched for an option to do so with no luck.
http://jsfiddle.net/KwW5n/2/ reflects our setup - we're using a simple -element as a base for our select2-functionality:
$('#source').select2();
This worked for me on select2 v4:
// keep search input, but avoid autofocus on dropdown open
$('#research .filter').on('select2:open', function (e) {
$('.select2-search input').prop('focus',false);
});

Sometimes select2 "steals" focus from other elements. After messing around for quite a bit, I just used this solution below.
At the very end of the event handler for the YourSelect2.on('change', function(){
setTimeout(firstInputFocus, 300);
}
function firstInputFocus() {
$("YourSelect2").focus();
}
By setting this slight delay it works. I am able to change focus away from the dropdown. Following the "change" event for select2, it does something internal to the select2 code which prevents you from IMMEDIATELY changing focus. Inserting this slight delay did the trick for me at any rate.
Ok, I am not sure if changing the focus is possible unless you change the select2 script itself (I could be wrong about this though). As a workaround what you could do is hide the search box by setting minimumResultsForSearch property to a negative value.
<select id="test">
<option>1</option>
<option>2</option>
</select>
And then:
$(document).ready(function() {
$('#test').select2({
minimumResultsForSearch: -1
});
});
Fiddle
None of the solutions posted here worked for me so I did this work around:
This will make the search input readonly when opened (prevents keyboard on mobile), then when you click the input it removes readonly and opens keyboard.
$('#myselectbox').select2({placeholder: "Select Something"}).on('select2:open', function(e){
$('.select2-search input').attr('readonly',true);
});
$('body').on('click', '.select2-search input', function(){
$(this).attr('readonly',false);
});
The only 'solution' I found is to remove .select2-input and .select2-focusser right after creation of the dropdown. This only works fine when you don't need the input field for searching, e.g. when the list is short enough.
Removing only .select2-focusser at least prevents the keyboard from popping up when an option was selected.
If you want to disable the searchbox and also the auto focus as a text input, e.g. preventing ios browsers to scroll-in the keyboard, use this code:
$('select').select2({});
// will remove the searchbox and focus initially
$(".select2-search, .select2-focusser").remove();
// will remove the searchbox and focus on selection/close
$('select').on('select2:closing', function (e) {
$(".select2-search, .select2-focusser").remove();
});
Although #Choma's answer is fine, it will alter the select2 default behavior on both desktop and mobile devices.
I had to find a solution for a responsive website: prevent the auto-focus of the search input only on mobile devices, and keep the default behaviour on desktops.
In order to detect the mobile devices, I've used Modernizr library, which can test for the existence of Touch Events in the browser.
We can use Modernizr.touch on Modenizr v2, which will return true if touch events are supported, or false otherwise.
So we can modify #Choma's answer like this:
$('select').on('select2:open', function() {
if (Modernizr.touch) {
$('.select2-search__field').prop('focus', false);
}
});
Demo:
https://codepen.io/andreivictor/full/QmKxOw/
Tested on:
Desktop: IE 11, Chrome, Firefox, Opera, Safari
Android 4.2.2
Android 5.0.1 (Samsung Galaxy S4)
Android 6.0.1 (Samsung Galaxy S7 Edge)
iOS 11.2.5 (iPhone 8)
iOS 10.3.2 (iPhone 6 Plus)
iOS 10.3.2 (iPad Mini 3)
I got JQuery's "too much recursion" error in the console when using Choma's solution.
The following worked for me for v4:
// keep search input available, but avoid autofocus and thus mobile
// keyboard appearing when dropdown opens.
$('body').on('select2:open','#subject', function (e) {
$('#modal .select2-search input').attr('readonly',true);
$('#modal .select2-search input').click(function(ev){
$('#modal .select2-search input').attr('readonly',false);
});
});
As you can tell this select2 field is on a modal with the id modal and the select2 field itself has an id of subject. Of course change the selector to what's appropriate for your own code.
It basically adds a readonly attribute to the input when the select2 field opens preventing a mobile keyboard from appearing, and then removes it when the search field is clicked/pressed on allowing the keyboard to appear only then.
Following trick worked for me. You can disable input search field of select2 element :
$('select').on('select2:opening', function() {
$('.select2-search__field').attr("autocomplete", "new-password");
});
setTimeout(function(){ $('.select2-search__field').attr("autocomplete", "new-password"); }, 2000);
maybe someone need~
I've tried this and it works~
$('#selectID').on('select2:opening', function (e) {
e.preventDefault();
});
The solution worked perfectly for me. tested on mobile
// prevent auto-focus on select2 search input
$('select').on('select2:opening', function(e) {
$('.select2-search input').prop('focus', 1);
});

jquery ui of drupal not working

Version Drupal 7.16
I'm trying to use draggable of jquery in Drupal way :
I have a simple page (with hook_menu) wich call an js and render a simple div with the good class to draggable :
(function($) {
Drupal.behaviors.testJs = {
attach : function(context, settings) {
$('.test-js').draggable();
});
}
}
})(jQuery);
This js is load.
I add library of jquery Drupal :
drupal_add_library('system', 'ui');
or
drupal_add_library('system', 'ui.draggable');
But nothing happen....
When I had an external jquery like :
drupal_add_js('http://ajax.googleapis.com/ajax/libs/jquery/1.5/jquery.min.js', 'external')
draggable work.
I try to enable jquery update module, but nothing more....
It is most likely that the hook you are calling isn't called int the right order. template_process_html is where css and js are finalized and rendered to template variables. Try adding your code in hook_preprocess_html and see if that works. Otherwise find a hook that is called before template_process_html like hook_init. If that doesn't work give a more detailed code sample of how you are trying to achieve this.

ie9: annoying pops-up while debugging: "Error: '__flash__removeCallback' is undefined"

I am working on a asp.net mvc site that uses facebook social widgets. Whenever I launch the debugger (ie9 is the browser) I get many error popups with: Error: '__flash__removeCallback' is undefined.
To verify that my code was not responsible I just created a brand new asp.net mvc site and hit F5.
If you navigate to this url: http://developers.facebook.com/docs/guides/web/#plugins you will see the pop-ups appearing.
When using other browsers the pop-up does not appear.
I had been using the latest ie9 beta before updating to ie9 RTM yesterday and had not run into this issue.
As you can imagine it is extremely annoying...
How can I stop those popups?
Can someone else reproduce this?
Thank you!
I can't seem to solve this either, but I can at least hide it for my users:
$('#video iframe').attr('src', '').hide();
try {
$('#video').remove();
} catch(ex) {}
The first line prevents the issue from screwing up the page; the second eats the error when jquery removes it from the DOM explicitly. In my case I was replacing the HTML of a container several parents above this tag and exposing this exception to the user until this fix.
I'm answering this as this drove me up the wall today.
It's caused by flash, usually when you haven't put a unique id on your embed object so it selects the wrong element.
The quickest (and best) way to solve this is to just:
add a UNIQUE id to your embed/object
Now this doesn't always seem to solve it, I had one site where it just would not go away no matter what elements I set the id on (I suspect it was the video player I was asked to use by the client).
This javascript code (using jQuery's on document load, replace with your favourite alternative) will get rid of it. Now this obviously won't remove the callback on certain elements. They must want to remove it for a reason, perhaps it will lead to a gradual memory leak on your site in javascript, but it's probably trivial.
this is a secondary (and non-optimal) solution
$(function () {
setTimeout(function () {
if (typeof __flash__removeCallback != "undefined") {
__flash__removeCallback = __flash__removeCallback__replace;
} else {
setTimeout(arguments.callee, 50);
}
}, 50);
});
function __flash__removeCallback__replace(instance, name) {
if(instance != null)
instance[name] = null;
}
I got the solution.
try {
ytplayer.getIframe().src='';
} catch(ex) {
}
It's been over a months since I last needed to debug the project.
Facebook has now fixed this issue. The annoying pop-up no longer shows up.
I have not changed anything.

sIFR3 show text while loading

I am using sIFR3 on a website. I remember in sIFR2 you coul use this sIFR.bHideBrowserText = false; to show the text before sIFR kicks in.
How do you do this in sIFR3 and where do you put the code?
Thanks for your help.
C
The feature as it existed in sIFR 2 no longer exists in sIFR 3. You could achieve the same affect like this, though:
sIFR.autoInitialize = false;
sIFR.activate(movie);
sIFR.removeFlashClass();
sIFR.replace(movie, { selector: 'h1' });
window.onload = function(){
sIFR.setFlashClass();
sIFR.initialize();
};
Where, of course, movie is the appropriate variable that references the Flash movie. You might want to connect to the onload event through another JavaScript framework. You must wait until full page load, things like $(document).ready() (jQuery) will not work reliably cross-browser.
