I'm making a naviget menu like IBM's website, when mouse hover it will slidedown a pannel. I use jQuery's slidedown, and it seems work well but when you fisrt slidedown it, it will stuck for a moment like this.
And after about 0.2 second，it continue to slidedown, this time works will.
Confusely if you redo the above opreate immediately, it slidedown smoothly and not stuck. And after one minute or refrash the website it stuck again.
I check this problem for two day, and I found this may cause by the image which need some time to load, beacuse when I remove the image it works well. But I don't know how to fix it, i'm already add overflow: hidden in all parents div, even use transition to replace the jQuery slidedown but it stuck too. What's more I can't rewrite the code of this part beacuse it's written by other person and I don't really know what have he down.
There are some codes I wrote or I know how it works:
HTML:
<div class="nav-item-con clearfix <#if 1!=field.index>none</#if>">
Javascript:
if($(this).parent().index() === current) {
if(!expanded) {
expanded = true;
$(this).stop().slideDown(250);
}
else {
$('.nav-item').css('display', 'none');
$(this).css('display', 'block');
}
}
CSS:
#header-box .nav .nav-item {
position: absolute; top: 3.5rem; right: 0; left: 0;
/*background: #20273C;*/
display: none;
background: rgba(32,39,60,0.8);
I'm appreciate if you know how to solve this problem.

I've been trying to change image source on hover, however i can use mousehover function with class name and do this. The challenge here is i'm going to dynamically call more divs with same class name so i'm trying to achieve this using the this method. for some unknown reason i couldn't execute my below code. can anyone suggest what seems to be the problem? Pasting my code below
$(".img_staff").mouseover(function() {
alert(2);
$(this).find('.staffimg:first-child').css("display","none");
$(this).find('.staffimg:nth-child(2)').css("display","block");
alert(3);
});
Both the alerts are working fine just the inbetween 2 lines are not working. i want to achieve this effect like moca tucson site's contact page
https://moca-tucson.org/contact/
I'm trying to recreate the same effect using Jquery
Apart from changing the image, the link that your provided also uses CSS transitions to bring that "image transition" effect.
Here's the similar effect with just CSS, without any javascript.
HTML:
<div>
<img src="https://moca-tucson.org/wp-content/uploads/2017/05/Ginger_Staff_Photos_001-800x800.jpg">
<img src="https://moca-tucson.org/wp-content/uploads/2017/05/Ginger_Staff_Photos_002-800x800.jpg">
</div>
CSS:
div img:last-child { opacity: 0 }
div:hover img:first-child { opacity: 0 }
div:hover img:last-child { opacity: 1 }
img {
position: absolute;
transition: 0.3s;
}
Here I am again, drowning in my noobness. I have been searching for literally HOURS to solve this problem! I am totally a beginner in jQuery/Javascript so I need some help.
This is what I want to do:
I have a navigation bar that when you click on a button, it hides it, then when you click again, it toggles it back, so the navigation bar is visible again. I have done this with jQuery and it works perfectly.
Now what happens is that, when you click that button and hide the navbar, I want the div content to slide to the left a few pixels and take up the full width (thus growing a bit bigger and filling up the useless whitespace, I especially want this for mobile-users). Again, this works perfectly.
However...if I click back on the famous button, the navigation bar comes back but the div content is still to the left, slightly hidden by the navbar. Whereas I want that when to navigation comes back, the div content comes back to its original place and width aswell.
Thus I have tried many many different codes but nothing seems to work! It either stays left or it just does not do anything. Although interesting and fun, it gets kind of frustrating after a few hours.
Here are a few things I have tried:
-toggle
-animate/stop
-if/else
-Get x position
I did not save any jQuery/javascript code but if need be, I shall provide a snippet. The reason I do not want to provide any code is because it is insanely LONG and confusing and complex!
As such, thank you very much in advance for your help! =)
Ah one last thing: Again, please keep in mind that you are talking to a beginner! So may you please be very specific and methodical (and keep it simple if possible ^^'), I would very much appreciate it since I have been searching for hours on Google and stackoverflow.
Oh woops I forgot! I do not use pixels for my units. I use "%" for the sake of responsiveness...I don't know if that actually works with jQuery...Enlighten me!
**ALRIGHT! Here is my super complicated fiddle...Somehow the jQuery is not working in my fiddle but it is working on my browser.
<html>Some super random code because it won't let me post fiddle without it but all my code is in the fiddle...</html>
https://jsfiddle.net/czcvucxL/1/**
you can get it done toggling a class from .content1 instead of using jquery
Demo
$(document).ready(function(){
$("#CharaCircle a").click(function(){
$("#Header").animate({width:'toggle'},350);
$("#Sidebar, #Sidebar ul li").animate({height:'toggle'},250);
$(".content1").toggleClass("fullwidth");
return false;
});
});
add this class
.fullwidth {
width: 95%;
left: 0;
margin-left: 0;
}
add these to .content1 so the div starts with 10% on the left and allow the animation(transition)
.content1{
left: 10%;
-webkit-transition: left 0.2s ease-in, width 0.2s ease-in;
transition: left 0.2s ease-in, width 0.2s ease-in;
}
EDIT: if you want it only with jquery Demo
$(document).ready(function () {
$("#CharaCircle a").click(function () {
$("#Header").animate({
width: 'toggle'
}, 350).toggleClass("hidden");
$("#Sidebar, #Sidebar ul li").animate({
height: 'toggle'
}, 250);
var properties;
var $content = $(".content1");
//build your set of properties width and marginleft
//are the ones you need to change
if ($("#Header").hasClass("hidden")) {
properties = {
width: "100%",
marginLeft: "0"
};
} else {
properties = {
width: "62%",
marginLeft: "19.4%"
};
}
$content.animate(properties, 250);
return false;
});
});
I tried a lot to solve the following: A click on "#pageTitle" should open the "#expandMenu". The expandMenu is exactly located in the bottom of the menubar. As you can see in CSS, there is a hover effect on the background-color. The code works fine so far, but even thought I still have a problem: The menubar should stay in the hover-color, till the toogleMenu gets closed. The user need to reach the expandMenu with his mouse for interacting. But after that, with my current code the via jQuery added css doesn't reset itself to the default css-hover mode.
It also would be nice, if the solution could include the possibility to add some further events, for example a switching icon (open, closed)
The CSS:
#expandMenu {
background-color: #009cff;
opacity: 0.8;
height:65px;
width:100%;
display:none;
}
#menubar {
height:95px;
width: 100%;
color:#FFF;
}
#menubar:hover {
background-color:#0f0f0f;
transition: background-color 0.3s ease;
color:#FFF;
}
jQuery:
$(document).ready(function(e){
$("#pageTitle").click(function() { $('#expandMenu').slideToggle( "fast");
$('#menubar').css( "background-color", "#0f0f0f" ); } );
})
HTML:
<div id="menubar">
<div id="pageTitle">Start</div>
</div>
<div id="expandMenu">
</div>
I have created a fiddle here that I think captures your page pretty well. I have tweaked the css class for the menubar a little bit so that the text stays visible, but the main change I have made is adding a class to the #menubar rather than directly applying the new background color. Then when you are hiding the #expandMenu you can remove the class to go back to the original color, whatever it was.
I check whether the expandMenu is visible and adjust the classes accordingly:
if ($('#expandMenu').is(':visible'))
{
$('#menubar').removeClass('menu-active');
}
else
{
$('#menubar').addClass('menu-active');
}
I check this state before I toggle the menu item because the slideToggle takes some time to finish, and the div is not visible immediately after the call. Checking its state before applying the animation avoids this problem.
I have installed an infinite scroll script to my Tumblr blog, and am now in the process of adding a scroll-to-top button. I want this button to fade in once the user scrolls down past a certain point, and fade out when they scroll back up. I also want it to provide a smooth scroll, not just a jump to the top.
I am fluent with HTML and CSS, though I unfortunately know basically nothing about JavaScript and jQuery. I found this tutorial for the JS side of things which taught me how to get the desired scroll button. Everything worked great, but the only problem is that the fadeOut doesn't work - the element simply disappears. Sometimes, if I am lucky, it will start fading out a little for a microsecond or so, but then disappear.
Here is the JavaScript I'm using:
<script src='http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js'></script>
<script>
$(function () {
$("#gotop")
.hide();
$(window).scroll(function () {
if ($(this).scrollTop() > 400) {
$('#gotop').fadeIn(500);
} else {
$('#gotop').fadeOut(500);
}
});
$('#gotop').click(function () {
$('html,body').animate({
scrollTop: 0
}, 400);
return false;
});
});
</script>
I have a simple anchor element in my HTML, styled in CSS using the id #gotop:
Top
CSS:
#gotop {position: fixed;
right: 2em; bottom: 2em;}
As it is, everything works fine, except for the fade out.
I've browsed the internet for similar such issues. I tried various things which I came across, though most of it was greek to me unfortunately.
Edit: I just had a thought. Is it possible that the fade out doesn't occur, because before it has time to fade out, the page has already scrolled back above the "hidden" zone and the element is immediately set to be hidden?
If anybody knows anything, it'd be much appreciated - thanks for your time!
Hope this helps
Js Fiddle Demo
$(function () {
$('#gotop').hide();
$(window).scroll(function () {
if ($(this).scrollTop() > 400) {
$('#gotop').fadeIn(500);
} else {
$('#gotop').fadeOut(500);
}
});
$('#gotop').click(function () {
$('html,body').animate({
scrollTop: 0
}, 400);
return false;
});
});
Okay, after some mucking around I managed to figure out the problem.
It turns out that I had set all elements on my page to have a CSS3 transition assigned to them, through use of the * selector:
* {margin: 0; padding: 0;
transition: all 0.5s;
-webkit-transition: all 0.5s;
-moz-transition: all 0.5s;
-o-transition: all 0.5s;}
I did this for convenience so that any hover I had would have a nice transition. However, it seems that this was what was causing my scroll-to-top button to misfunction!
I would suggest that anybody who is having the same problem as my checks any transitions they've used, and ensure that they're not affecting the to-top button. If there are any doubts, try removing them temporarily just to check.
Hope this helps.
I'm not really sure where to start on this, but I have a menu done in jquery. When you hover over right now, it does some fade in/out effects to the text, and links are manually handeled.
I wanted to add a simple line, maybe done in css? to go under each li a item when you are hovering as well, sliding to the li you hover over, not just appearing.
I just have no idea where to start with something like that, as I've never really done it before without an image (preferrably). It would of coarse need to start somewhere and move alone the ul and stop wherever it is when you leave the div with your mouse, and I'd like to keep it on when you click a link. I'm not asking anyone to make this for me though (unless you feel like it), just to get pointed on the right direction. I've seen some free codes with menus that do this, and attempted to use them, or model off them, but it woulnd't work with my menu.
Fiddle
I did this a while ago, maybe it is what you need. It will calculate the width of the anchor element you are hovering and grow an underliner element (a div) to both its width and position
//underliner
$('#menu a').hover(function(){
var position = $(this).position(); var width = $(this).width();
$('#underliner', '#menu').animate({width: width,left: position.left}, 200 );
});
$('#menu').hover(function(){
$('#underliner', '#menu').animate({opacity: 1}, 200).show();
}, function () {
$('#underliner', '#menu').animate({opacity: 0}, 200).hide();
});
CSS for the underline-element (change height and bg color as you seem fit)
#underliner {
display: none;
position: relative;
height: 5px;
line-height: 5px;
font-size: 1px;
background-color: #44c8f5;
width: 1px;
opacity: 0;
filter: alpha(opacity=0);
}
HTML
<div id="menu">
<ul>
list items with <a href>'s
</ul>
<div id="underliner"></div>
</div>
edit: I tried merging it with your code, but as you did not include the html, I had to guess how your 'navibar' was laid out. Anyway, try this fiddle: http://jsfiddle.net/c_kick/DuWcz/
