Remove transparency on menu drop down Javascript

I've been trying to implement a feature that removes the transparency of the dropdown menu on my website so that it is actually readable for visitors.
The code I am currently using, which removes transparency on scroll but not on drop down is:
$(document).ready(function(){
var stoptransparency = 100; // when to stop the transparent menu
var lastScrollTop = 0, delta = 5;
$(this).scrollTop(0);
$(window).on('scroll load resize', function() {
var position = $(this).scrollTop();
if(position > stoptransparency) {
$('#transmenu').removeClass('transparency');
} else {
$('#transmenu').addClass('transparency');
}
lastScrollTop = position;
});
$('#transmenu .dropdown').on('show.bs.dropdown', function() {
$(this).find('.dropdown-menu').first().stop(true, true).slideDown(300);
});
$('#transmenu .dropdown').on('hide.bs.dropdown', function() {
$(this).find('.dropdown-menu').first().stop(true, true).slideUp(300);
});
});
I tried changing it to this (and variations of this) but can't seem to get it to work:
$(document).ready(function(){
var stoptransparency = 100; // when to stop the transparent menu
var lastScrollTop = 0, delta = 5;
$(this).scrollTop(0);
$(window).on('scroll load resize', function() {
var position = $(this).scrollTop();
if(position > stoptransparency) {
$('#transmenu').removeClass('transparency');
} else {
$('#transmenu').addClass('transparency');
}
lastScrollTop = position;
});
$('#transmenu .dropdown').on('show.bs.dropdown', function() {
$(this).find('.dropdown-menu').first().stop(true, true).slideDown(300);
$('#transmenu').removeClass('transparency');
});
$('#transmenu .dropdown').on('hide.bs.dropdown', function() {
$(this).find('.dropdown-menu').first().stop(true, true).slideUp(300);
$('#transmenu').addClass('transparency');
});
});
Any help would be greatly appreciated!
Thanks!

Without the html that this is hooking into it's a bit difficult to answer your question.
But given the fact that scrolling gets the job done, the only element I can see that could be preventing the functionality you want is that your selector to add show event handler is either selecting nothing in particular or an element in the DOM that is not the bootstrap dropdown element that triggers 'show.bs.dropdown', which is my reasoning for the first statement.
You can try the following debug code to verify:
// Should log to console with 'selected' if selector works alternatively 'not selected'
console.log($('#transmenu .dropdown').length > 0 ? 'selected' : 'not selected');
// Log to console when show event triggered
$('#transmenu .dropdown').on('show.bs.dropdown', function() {
console.log('triggered');
});
Hope that helps you find a solution. Happy coding!

see the documentation at http://api.jquery.com/on/ and it should become obvious why your fancy named events are never being triggered (without defining any event namespace in the first place).
$('#transmenu .dropdown')
.on('show', function() {})
.on('hide', function() {});
the DOM selector also might be #transmenu.dropdown instead of #transmenu .dropdown (depending if id and class attributes are present on the DOM node to select - or if one selects the parent node by id and there is/are nested node/s with a class attribute present).

How to leave Menu bar from the middle of the page on top while scrolling?

I wanted to do something like this mentioned here, so I used the following jsfidlle (that works pretty fine) to create my own http://jsfiddle.net/a2q7zk0m/1/, but with the custom menu included. Now it doesn't work, I guess it's probably because of the error in javascript:
$(document).ready(function() {
$(window).scroll(function(e) {
$el = document.getElementById('temp');
if ($(this).scrollTop() > 100) {
$el.addClass("fixedNav");
} else {
$el.removeClass("fixedNav");
}
});
});
that does not recognize the ID of the div and request the class from css, but unfortunately I cannot use class attribute here. Could you help me guys with solving that issue? Thanks!

Replace this line:
$el = document.getElementById('temp');
with this:
$el = $('#temp');
JSFiddle
Or wrap the $el into jQuery object:
$el = document.getElementById('temp');
// ...
$($el).removeClass("fixedNav");
JSFiddle
Also, You should move $el declaration outside of the $(window).scroll method (so that the element isn't searched in DOM while scrolling)
$(document).ready(function(){
var $el = $('#temp');
$(window).scroll(function (e){
if ($(this).scrollTop() >= 100 && !$el.hasClass("fixedNav")) {
$el.addClass("fixedNav");
}else if($(this).scrollTop() < 100 && $el.hasClass("fixedNav")){
$el.removeClass("fixedNav");
}
});
});

How to slide down a jQuery slideToggle when scaling a browser

I am having an issue with my slideToggle function. Once pressed it opens up the way I need it to. But when I scale the browser to test the responsive flow to the site the slideToggle still stays active instead of sliding down. I tried a few functions but nothing seems to work. Below is the scrip I am using without the code to slide down when it hits a specific screen resoultion. How would I go about fixing this issue?
$('#more').click(function () {
var open = $('header').is('.open');
$('#footerPanel')['slide' + (open ? 'Up' : 'Down')](400);
$('header').animate({
bottom: (open ? '-' : '+') + '=120' }, 400, function () {
$('header').toggleClass('open');
});
});
$('#menu').click(function () {
if ($('header').is('.open')) {
$('header')
.removeClass('open')
.animate({
'bottom': "-=120"
}, function () {
var $footer = $('.activetoggle');
if ($footer.length)
$footer
.toggleClass('activetoggle footerButton')
.text('Footer');
});
$('#footerPanel').slideUp(400);
}
});
$('.footerButton').click(function () {
var $this = $(this);
$this.toggleClass('footerButton');
if ($this.hasClass('footerButton')) {
$this.text('Footer');
} else {
$this.text('Close');
}
$(this).toggleClass('activetoggle');
});
My Code
http://jsfiddle.net/wyze/XqUp4/4/

Try if this works for you. I have added to check whether the width is 780(you can change it), when the panel to slide down. Try adding this in you fiddle and check if this works
$(window).resize(function(){ //check when window resize
if($(window).width() < 780){ // check when the window width is less than 780
if ($('header').is('.open')) {
$('header')
.removeClass('open')
.animate({
'bottom': "-=120"
});
$footer = $('.activetoggle');
if ($footer.length) {
$footer.toggleClass('activetoggle footerButton').text('Footer');
}
$('#footerPanel').slideToggle(400);
}
}
});

jQuery Highlight Nav links on scroll not working

I'm extremely new to JavaScript so I apologize in advance. I'm trying to create a one page html document for a school project using a list of links for navigation that change when the anchor is scrolled to. I've tried various different methods found on Jfiddle and through stackoverflow. This is the method I am trying now: http://jsfiddle.net/m2zQE/
var topRange = 200, // measure from the top of the viewport to X pixels down
edgeMargin = 20, // margin above the top or margin from the end of the page
animationTime = 1200, // time in milliseconds
contentTop = [];
$(document).ready(function () {
// Stop animated scroll if the user does something
$('html,body').bind('scroll mousedown DOMMouseScroll mousewheel keyup', function (e) {
if (e.which > 0 || e.type == 'mousedown' || e.type == 'mousewheel') {
$('html,body').stop();
}
});
// Set up content an array of locations
$('#nav').find('a').each(function () {
contentTop.push($($(this).attr('href')).offset().top);
});
// Animate menu scroll to content
$('#nav').find('a').click(function () {
var sel = this,
newTop = Math.min(contentTop[$('#nav a').index($(this))], $(document).height() - $(window).height()); // get content top or top position if at the document bottom
$('html,body').stop().animate({
'scrollTop': newTop
}, animationTime, function () {
window.location.hash = $(sel).attr('href');
});
return false;
});
// adjust side menu
$(window).scroll(function () {
var winTop = $(window).scrollTop(),
bodyHt = $(document).height(),
vpHt = $(window).height() + edgeMargin; // viewport height + margin
$.each(contentTop, function (i, loc) {
if ((loc > winTop - edgeMargin && (loc < winTop + topRange || (winTop + vpHt) >= bodyHt))) {
$('#nav li')
.removeClass('selected')
.eq(i).addClass('selected');
}
});
});
});
I'm still not having any luck. I've already searched to see if I could debug the problem and have tried changing the order of the code as well as the order of calling jquery.
Here is a link to the site: https://googledrive.com/host/0BwvPQbnPrz_LMlZDeGlFY2Yydmc/index.html
I used html5boilerplate as a starting point.Thank you in advance.

Don't have much time to look into your code, but when I input the line
Math.min(contentTop[$('#nav a').index($(this))], $(document).height() - $(window).height())
into the console of developer tools, it return NaN.
So I guess the problem is you don't have your scrollTop correctly set.
I suggest you give each element an id and try:
$('html, body').animate({
scrollTop: $("#elementID").offset().top
}, 2000);
or if you insist not giving id,
$('html, body').animate({
scrollTop: $("#container-fulid:nth-child(2)").offset().top
}, 2000);
but notice that this is not working on all browser as the nth-child selector is a CSS3 selector.
Or, if you know how to correctly use other's work, you may try to use bootstrap 3.0, where there is already a function named scrollspy included, which do exactly the thing you are doing.

Jquery show and hide elements according to position

I am trying to make a carousel of sorts. I am kind of stuck with hiding and displaying the next and precious buttons once a div moves to the far left and right of its container.
I think i have everything correct regarding calculating the widths but for some reason when you click the buttons, elements stay hidden irrespective of the conditional comments which should dictate when they should be hidden or shown.
Here is a link to what i have thus far. Click the MoveLeft and MoveRight buttons. http://www.ehbeat.com/test/
<script type="text/javascript">
$(document).ready(function () {
//Check width of Gallery div
var galleryWidth = $("#Gallery").innerWidth();
//Check width of GalleryItem
var galleryItemWidth = $(".GalleryItem").innerWidth();
//Check distance from left
var position = $('.GalleryItem').position();
var galleryItemLeft = position.left;
$(".MoveRight").click(function () {
$(".GalleryItem").animate({
"left": "+=50px"
}, "slow");
$(".GalleryItem2").animate({
"left": "+=100px"
}, "slow");
});
$(".MoveLeft").click(function () {
$(".GalleryItem").animate({
"left": "-=50px"
}, "slow");
$(".GalleryItem2").animate({
"left": "-=100px"
}, "slow");
});
$(".Controls").live('click', function () {
if (galleryItemLeft >= "0") {
$('.MoveRight').hide();
}
else {
$('.MoveRight').show();
}
});
if (galleryItemWidth == galleryWidth - galleryItemWidth) {
$('.MoveLeft').hide();
}
});
</script>

It looks like you setup all of your variables inside the $(document).ready() call.
This means that while they're being set on load, they're not getting updated with each click.
Your galleryItemLeft, galleryItemWidth and galleryItemWidth variables need to be updated on each click, so I'd recommend re-assigning the values in each click (by moving the assignment into the live functions)
Edit Also, as your last if statement is excluded from any click function, it'll need to be relocated to inside the live click events as well.
-Chris

Chris is right, code should look like this:
$(".Controls").live('click', function() {
position = $('.GalleryItem').position();
galleryItemLeft = position.left;
if(galleryItemLeft > "0") {
$('.MoveRight').hide();}
else{
$('.MoveRight').show();
}
if(galleryItemWidth == galleryWidth - galleryItemWidth) {
$('.MoveLeft').hide();
}
});
