.delay() not working on my .show() JQuery

I'm trying to make my footer disappear when on a mobile device and only when the keyboard is open. Which I have working perfectly, however the issue is that the footer reappears before the keyboard has time to close. Which is because I'm using the event from the textbox having focus not the keyboard being open. So I thought the best way to resolve this is with a .delay() however, this isn't working at all. Anyone have any ideas here?
<script>
var isMobileView = false; //global variable
$(document).ready(function () {
function setScreenWidthFlag() {
var newWindowWidth = $(window).width();
if ( $(window).width() > 600) {
isMobileView = false;
}
else {
isMobileView = true;
}
}
$(".tbinputArea").focus(function() {
if(isMobileView)
$("#footer").hide();
});
$(".tbinputArea").focusout(function() {
if(isMobileView)
$("#footer").delay(500).show();
});
setScreenWidthFlag();
$(window).on("resize", function (e) {
setScreenWidthFlag();
});
});
</script>

$("#footer").delay(500).show(0);
Try this.

refer this explanation precisely explained the reasons for it http://www.mattlunn.me.uk/blog/2012/06/jquery-delay-not-working-for-you/
Delay is just for queue delay not any event delay so try to add some events within like fadeIn or similar.

Switch click and hover events based on width

I want to toggle events based on width. for mobile only click event should work. for desktop hover event should work. while page loading my code working properly when resize my code is not working.
please help me why my code is not working. Thanks in advance
$(document).ready(function(){
function forDesktop(){
$(".popover-controls div").off('click');
$(".popover-controls div").on('hover');
$(".popover-controls div ").hover(function(e){
//popup show code
});
}
function forMobile(){
console.log("mobile");
$(".popover-controls div").off('hover');
$(".popover-controls div").on('click');
$(".popover-controls div").click(function(e){
//popop show
});
}
function process(){
$(window).width() > 600?forDesktop():forMobile();
}
$(window).resize(function(){
process()
});
process();
});

Its very simple, 1st you cant write this much of code for every event. We have to come up with very simple solution, here is how it works
1st check the width of the Page in JS and assign Desktop/Mobile Class on body :
function process(){
if( $(window).width() > 600){
$("body").removeClass("mobile").addClass("desktop");
}else{
$("body").removeClass("desktop").addClass("mobile");
}
}
$(window).resize(function(){
process()
});
Now, you have execute the command for hover and click:
$(document).on('mouseover', 'body.mobile .popover-controls div',function(e){
alert("hover");
});
$(document).on('click', 'body.desktop .popover-controls div',function(e){
alert("click");
console.log("click");
});
I Hope this will work for you. :)
Check the Js fiddle Example: http://jsfiddle.net/asadalikanwal/xcj8p590/
I have just created for you, also i have modified my code

You could use a JavaScript Media Query to determine the width of the screen as detailed here.
var mq = window.matchMedia( "(min-width: 500px)" );
The matches property returns true or false depending on the query result, e.g.
if (mq.matches) {
// window width is at least 500px
} else {
// window width is less than 500px
}

First Detect the Mobiles/Tablets Touch Event:
function is_touch_device() {
return 'ontouchstart' in window // works on most browsers
|| 'onmsgesturechange' in window; // works on ie10
};
Then Try like this:
function eventFire() {
var _element = $(".popover-controls div");
// True in Touch Enabled Devices
if( is_touch_device() ) {
_element.click(function(e) { .... });
}
else {
// apply Hover Event
_element.hover();
}
}
No need to detect width of devices ;)
There is one more solution with third party and Most popular library is Modernizr

This worked for me. It's a combination of the matchMedia() functionality #Ḟḹáḿíṅḡ Ⱬỏḿƀíé shared as well setTimeout() functionality #Jeff Lemay shared at TeamTreeHouse.com
The primary thing I contributed to was the use of the .unbind() functionality. It took me quite a while to figure out that this was necessary so the .hover() and .click() functions don't cross wires.
//Add/remove classes, in nav to show/hide elements
function navClassHandler(){
if($(this).hasClass('active')){
$('.dropdown').removeClass('active');
}else{
$('.dropdown').removeClass('active');
$(this).addClass('active');
}
}
function handleNav() {
//instantanteous check to see if the document matches the media query.
const mqM = window.matchMedia('(max-width: 1025px)');
const mqD = window.matchMedia('(min-width: 1025px)');
$('.dropdown').unbind(); //necessary to remove previous hover/click event handler
if (mqM.matches) {
console.log("Handling mobile");
$('.dropdown').click(navClassHandler);
} else {
console.log("Handling desktop");
$('.dropdown').hover(navClassHandler);
}
}
// we set an empty variable here that will be used to clearTimeout
let id;
/* this tells the page to wait half a second before making any changes,
we call our handleNav function here but our actual actions/adjustments are in handleNav */
$(window).resize(function() {
clearTimeout(id);
id = setTimeout(handleNav, 500);
});
//As soon as the document loads, run handleNav to set nav behavior
$(document).ready(handleNav);

Current page in navigation using Javascript and jQuery

I'm trying to set the current page to reflect in a main navigation bar. I've set a div in each page for JS / jQuery to check it's the right page with the following code:
$(document).ready(function() {
if ($('div').is('#example1-page')) {
$("a#nav-example1").addClass('nav-example1-current');
$("#nav-example1 p").css('display','block');
}
else if ($('div').is('#example2-page')) {
$("a#nav-example2").addClass('nav-example2-current');
$("#nav-example2 p").css('display','block');
}
else if ($('div').is('#example3-page')) {
$("a#example3").addClass('nav-example3-current');
$("#nav-example3 p").css('display','block');
}
});
I know there has to be a better way to do this with an array or something where I'm not repeating myself. Something where you can store the links IDs in an array and by clicking on the link with the right ID JS will know to set the current page in the navigation. I'm not sure where to start though.

Arrays of arrays are your friend :). Try this:
$(document).ready(function() {
var pageCounter=3;
var pages=[];
for(var i=1;i<=pageCounter;i++){
var selectors=["#example"+i+"-page",
"a#nav-example"+i,
"nav-example"+i+"-current",
"#nav-example"+i+" p"];
pages.push(selectors);
}
for(var i=0;i<=pageCounter;i++){
if ($('div').is(pages[i][0])) {
$(pages[i][1]).addClass(pages[i][2]);
$(pages[i][3]).css('display','block');
break;
}
}
});
Note: the logic to initialize the pages array does not need to be part of document.ready.

Try this
$(document).ready(function() {
if ($('#example1-page').length) {
$("a#nav-example1").addClass('nav-example1-current');
$("#nav-example1 p").show();
}
else if ($(#example2-page').length) {
$("a#nav-example2").addClass('nav-example2-current');
$("#nav-example2 p").show();
}
else if ($('#example3-page').length) {
$("a#example3").addClass('nav-example3-current');
$("#nav-example3 p").show();
}
});

How to hide div on mouseout?

I'm trying to achieve a simple hover effect. When a user hovers an image (a view filled with images), it should show an extra div. No problem there.
But when I want to do the opposite thing, hide the same div when the user leaves the area of the div, it doesn't work: the div won't go away when leaving the div area (which should be done by default when using the hover, no?).
This is the code I use:
$(document).ready(function () {
$('.views-field-field-photo-fid').out(function () {
showDiv($(this), $('.views-field-title'));
});
$('.views-field-field-photo-fid').out(function () {
hideDiv($(this), $('.views-field-title'));
});
});
function showDiv(sender, object) {
$(object).show();
}
function hideDiv(sender, object) {
$(object).hide();
}
So far, I've tried .mouseenter, .mouseleave, .hover, .out, but nothing works to hide the div after leaving the div area.
UPDATE
I found the solution, more or less:
$(document).ready(function() {
$('#uicarousel-news-preview-block-2 .views-field-field-photo-fid').hover(
function() { $(this).find('.views-field-title').show(); },
function() { $(this).find('.views-field-title').hide(); }
)
});
But since there are a lot of .views-field-title, it's hiding/showing them too. So I figured to use the find, but no solution there.
Any ideas?

There is no jQuery function called out, I am not sure whether you are using a plugin or not. Anyway, this how a correct hover declaration should look like:
<script style="text/javascript">
$(document).ready(function() {
$('.views-field-field-photo-fid').hover(
function() {
showDiv($(this), $('.views-field-title'));
},
function() {
hideDiv($(this), $('.views-field-title'));
});
});
function showDiv(sender, object) {
$(object).show();
}
function hideDiv(sender, object) {
$(object).hide();
}
</script>
I suggest that you take a look at the jQuery.hover documentation.

Same browser version, 2 different javascript handlings

Problem solved: I removed the first function as it wasn't needed anyways, and now it all works in all browsers. Thanks for the posts though!
My issue here is that I have a javascript which on one server runs perfectly with no issues what-so-ever in IE. But on another server gives me 2 errors in IE.
It claims that my offset().top is either Null or not an object.
My fade in and out effect doesn't even become active.
Then I have another HUGE issue, which is that in FireFox NON of it all works.
OPS: This is a webpart, so additional javascripts running on the site might could intervene with the javascript I am trying to execute here. But I'm not sure.
I've tested this webpart in IE 8.0.7600.16385, on both servers.
Script:
<script type="text/javascript"
src="/_layouts/Progressive/Javascripts/jquery-1.4.3.js"></script>
<script type="text/javascript">
(function($) {
$.fn.goTo = function() {
// This is where IE on the second server claims the error to be.
$('html, body').animate({scrollTop: $(this).offset().top + 'px'}, 'fast');
return this;
}
})(jQuery);
function showParagraphs(sender) {
var id = sender.getAttribute('href');
if ($('#<%=paragraph.ClientID%>').hasClass("readable")) {
$('#<%=paragraph.ClientID%>').removeClass("readable");
highlightSelected(id);
}
else {
$('#<%=paragraph.ClientID%>').addClass("readable");
rmvClass(id);
}
};
function highlightSelected(id) {
$(id).goTo();
$(id).addClass("reading");
// This part is what isn't activated on the second server.
$('.reading').fadeOut(400).fadeIn(400).fadeOut(400).fadeIn(400);
// .reading only adds a gray background to the DIV.
};
function rmvClass(id) {
$('div').each(function() {
if ($(this).hasClass("reading")) {
$(this).removeClass("reading");
}
});
}
function toTop() {
$('div').each(function() {
$(this).removeClass("reading");
});
$('#<%=paragraph.ClientID%>').addClass("readable");
}
$(document).ready(function() {
$('#<%=q.ClientID%>').find('dd').hide().end().find('dt').click(function() {
$(this).next().slideToggle("fast");
});
$("#<%=q.ClientID%> dt").click(function() {
if ($(this).hasClass("selected")) {
$(this).removeClass("selected");
}
else {
$(this).addClass("selected");
}
});
});
</script>
Any thoughts or suggestions?

When
$(id)
returns an empty jQuery object, then ".offset()" will return null. You're calling that "highlightSelected" code with the "href" value from something, so perhaps what you think to be an "id" value that corresponds to something on the page, well it really doesn't. It's hard to know for sure, however, because you did not post any of the relevant HTML, nor did you even show where "showParagraphs()" is called!
