I'm using the Superslides script to create a responsive slideshow for a site. I have created a basic caption box that I want to be hidden and then slide in from the bottom when the slide going with the caption is display.
In the Superslide script the current slide gets a higher z-index (of 2, otherwise it is set to 0) and a display: block (otherwise 'none') change to it when it's coming into view.
I am not very good with Javascript so I am having a bit of trouble targeting my captions to animate in at the right time. I put together a script that is supposed to evaluate all the li tags (each li is a different slide) and if it has a z-index of 2 it changes the bottom margin of the caption div so it slides into view. My problem is that my script only targets the very first li instead of running through all of them. For the first li it works great, I just need it to run though the rest of the li's as well. Any suggestions are appreciated!
Script:
var li = document.querySelector('li[style]'),
inlinezIndex = li.style.zIndex;
console.log(inlinezIndex);
if(inlinezIndex == 2){
document.getElementById('caption').style.bottom = '300px';
$('#caption').css({'transition': '10s'});
}
else{
document.getElementById('caption').style.bottom = '0px';
}
HTML:
<div id="slides">
<ul class="slides-container">
<li class="slide1">
<img src="images/people.jpeg" alt="Cinelli">
<div id="caption">
<h1>Hello</h1>
<h2>This is a test</h2>

</ul>
<nav class="slides-navigation">
<i class="icon-chevron-right"></i>
<i class="icon-chevron-left"></i>
</nav>
</div>
Try using querySelectorAll instead of querySelector.
You could then loop through the li's and apply your styling, etc.
Also I see you are using multiple elements with the same id ("caption") and this is bad practice. Actually, I think it's invalid HTML according to the HTML5 specification as id's are supposed to be unique (look at this stackoverflow thread).
Example
var list = document.querySelectorAll('.slides-container li');
for (var i = 0; i < list.length; i++) {
var li = list[i];
var zIdx = li.style.zIndex;
// Use a class instead of id for captions
var caption = li.querySelector('.caption');
if (zIdx == 2) {
caption.style.bottom = '300px';
} else {
caption.style.bottom = '0px';
}
}
I'd also put css transitions in css (handy-dandy transitions):
.caption {
transition: bottom 10s;
}

I was trying to remove the whole parent div if it doesn't have the wc-gallery class on it. What I have in my script is the reverse of what I need. Basically it hide everything that has the wc-gallery on it.
SCRIPT:
// Additional Scripts
$(window).load( function() {
$(".gallery-container2 .gallery-item .wc-gallery").hide();
});
$(".gallery-container2 p").click(function() {
var id = $(this).data('id');
$("[data-id=" + id + "].gallery-item .wc-gallery").toggle()
});
$(function(){
$(".gallery-item").each(function(){
$(this).children('.wc-gallery').parents('.gallery-container2').hide();
});
});
Basically this will work fine if I Hide all the containers and display the child div afterwards though my content won't render due to script conflicts. Only way to solve this without conflict is to load first all of the containers then hide() or remove() them.
SCRIPT: (conflict due to onload content rendering)
$('.gallery-container2').hide();
$(function(){
$(".gallery-item").each(function(){
$(this).children('.wc-gallery').parents('.gallery-container2').show();
});
});
HTML: (1st set is the one should be visible 2nd set is the one that needs to be remove or hide.)
<ul>
<li><div class="gallery-container2">
<p data-id="1723"><strong>some text</strong></p>
<div class="gallery-item" data-id="1723">
<div class="wc-gallery" style="display: none;"></div>
</div>
</div></li>
<li><div class="gallery-container2">
<p data-id="2455"><strong>View before and after</strong></p>
<strong></strong>
<div class="gallery-item" data-id="2455">
<div><div></div></div>
</div>
</div></li>
</ul>
Loop through the '.gallery-container2' element and find out whether it has '.wc-gallery' children. if not hide the element.
$('.gallery-container2').each(function(){
var $this = $(this);
//find element with 'wc-gallery' class
var hasGallery = $this.find('.wc-gallery').length > 0;
if(!hasGallery){
$this.hide();
}
});
Pure JS you might do like this in ES6 terms.
var divsToHide = document.querySelectorAll("div div :not(.wc-gallery)");
for (var div of divsToHide) div.parentElement.parentElement.style.display = "none";
<div class="gallery-container2">
<p data-id="1723"><strong>some text</strong>
</p>
<div class="gallery-item" data-id="1723">
<div class="wc-gallery">first container</div>
</div>
</div>
<div class="gallery-container2">
<p data-id="1724"><strong>some text</strong>
</p>
<div class="gallery-item" data-id="1724">
<div>
<div>second container</div>
</div>
</div>
</div>
Try this. If div has children with class .wc-gallery than it will show the parent otherwise hide the parent.
$(function () {
$(".gallery-item").each(function () {
if($(this).children('.wc-gallery').length > 0)
$(this).parents('.gallery-container2').show();
else
$(this).parents('.gallery-container2').hide();
});
});
I need it to be a javascript solution only please. Please refer to this demo.
The goal is to hover the dots on the right bottom corner and swap the images accordingly. But what it does now is showing a blank page when hovering, and the whole ul becomes vertical and goes to top left corner. What did I do wrong here???

Thank you in advance!!
TL;DR
Here is the working fiddle: https://jsfiddle.net/2qz2srqs/3/
Reason
Your code was very close, but it had a few minor issues.
The first was a copy-paste error, you had two elements with the id of resistorDetail3.
Second, your syntax for the onmouseover event was incorrect. Prefix any javascript with javascript: and ensure it has proper syntax.
Third, your showDetail method expected a string id of the element to show. In your onmouseover declaration you had showDetail(resistorDetail1) instead of showDetail('resistorDetail1').
Finally, when you javascript is referenced in the HTML, you need to make sure you load the javascript first. Just by taking a look at the developer's console you could see that it through an error "showDetail is not defined.. I switched it to No wrap - in <body> and it worked fine.
BUT I highly recommend against directly referencing javascript from your HTML. Instead, load the HTML first and then use the DOM ready event of javascript to bind your events. That will increase your load time and make it easier to switch to something like jQuery/Zepto if needed.

Here's another working fiddle.
https://jsfiddle.net/2qz2srqs/4/
The issue was a couple things.
You were passing undefined vars into your onmouseover attributes. You wanted strings (I quoted them)
In JSFiddle, you don't automatically get the window scope, so you have to assign a function as a property of a window if you want to be able to hit it with an event attribute.
I want to run a generic javascript function with an element, sometimes multiple elements in the same HTML document. It seems to me the easiest way is to call the function from inside a DOM element. OK here's the problem. "this" refers the window element and I have seen how scope works for functions using "this" but I don't see how to get "this" to refer to an element.
I could do getElementById but I want a fairly generic javascript and not have to come up with unique IDs everytime I want to use it. getElementsByClasses may be a workaround but it just seems there should be an easier way to do this without relying on id's or classes.

The javascript. It's dh and ih that I need to pass to the function.
function valignimg() {
dh = /* div element */
ih = /* image (child element) */
topmargin = (dh.offsetHeight - ih.offsetHeight)/2;
return topmargin;
}
If you're not calling it from one of the elements (i.e. via event handler), you're going to have to use a selector of some kind, either ID or class as you highlighted, or name or tag name if that can work, or some combination. Somewhere along the way it will need to be specified. In even though you weren't keen on using class, that's likely your best option so I've highlighted it in this first example.
//warning - this event isn't supported on some older browsers like IE8
document.addEventListener("DOMContentLoaded", function(event) {

You can see, although my usage is pretty rudimentary, I've used getElementsByTagName as well, calling from a parent element other than document. The IDs I've added aren't used for locating anything, I'm just using them so that when I log to console you can see which element it really is, the same as with my horrendous misuse of the alt attribute on the images.
If you know that your only image elements on the page are the ones you're acting on, then maybe starting with document.getElementsByTagName('img') is the approach for you, and then get the div with the .parentNode property. This would remove the reliance on classes, but if you add other img tags to the page then you'd need some way to identify from each one whether it's once you want to run your align function against or not. The img tags you want to access have a common ancestor or parent that no other img tags do. I've added another snippet below that shows this. And you could combine these two approaches with a nest loop to get all img tags within multiple divs that all share a class, for example.
//warning - this event isn't supported on some older browsers like IE8
document.addEventListener("DOMContentLoaded", function(event) {
valignAll();
});
function valignimg(ih) {
//Only added the IDs for this purpose, not using them to select elements so there's no functional requirement for them.
console.log(ih.alt);
//This supposes that you know the image tag you want is always the first img element among dh's children.
dh = ih.parentNode;
console.log(dh.id);
var topmargin = (dh.offsetHeight - ih.offsetHeight) / 2;
console.log('dh.offsetHeight = ' + dh.offsetHeight);
console.log('ih.offsetHeight = ' + ih.offsetHeight);
console.log('topmargin = ' + topmargin);
ih.style.marginTop = topmargin + "px";
console.log('ih.style.marginTop = ' + ih.style.marginTop);
}
function valignAll(){
//if they're the only img tags on the page,
//document.getElementsByTagName('img'); will work fine.
//lets assume they aren't.
var images = document.getElementsByClassName('linksbox')[0].getElementsByTagName('img');
//I can grab the comment parent/ancestor by whatever means available, and then grab just its decendants by tag name.
alert(images);
for(i = 0;i < images.length;i++){
valignimg(images[i]);
}

*EDIT: Here's a link to a staging version of the site: http://staging-site.site44.com/ *
I am extremely new to jquery so I apologize if this question is extremely simple. What I'm trying to do on my website is first when the page is loaded have the content in my #topContent div fade in.
But along with this I'd also like my main navigation to use jquery hashtags to switch up the page content displayed in the #topContent div. I've read up a bit on how to do this in jquery and from what I've read I think I need create page sections within my main html doc that are hidden until a certain nav link is selected - then hide the content that is currently showing and show the content associated with the nav link that was just selected, how close am I?
Here's my attempt so far at doing this...
HTML
<nav id="headerNav">
<ul class="navList">
<li class="navItem">Products</li>
<li id="view-about" class="navItem">About</li>
<li class="navItem">Portfolio</li>
<li class="navItem">Contact</li>
</ul>
</nav>
</div>
</div>
<!-- topMain -->
<div id="topContentWrapper">
<div id="topContent">
<div id="#products">
<h2>Test worked! - products </h2>
<p>this test just worked sooo hard!</p>
</div>
<div id="#about">
<h2>Test worked! - about </h2>
<p>this test just worked sooo hard!</p>
</div>
<div id="#portfolio">
<h2>Test worked! - Portfolio </h2>
<p>this test just worked sooo hard!</p>
</div>
</div>
</div>
JS
// Fade In Effect
$(document).ready(function() {
$("#topContent").css("display", "none");
$("#topContent").fadeIn(2000);
$("a.transition").click(function(event){
event.preventDefault();
linkLocation = this.href;
$("#topContent").fadeOut(1000);
});
function redirectPage() {
window.location = linkLocation;
}
$("#view-about").click(function(event){
$("#products").fadeOut(1000);
$("#portfolio").fadeOut(1000);
$("#about").fadeIn(1000);
});
});
Ok, this code should work:
$(function(){
$last = null;
$(".navList li a").click(function(){
if ($last != null) $last.fadeOut(1000);
$last = $($(this).attr("href"));
$($(this).attr("href")).fadeIn(2000);
});
});
However, you will need to change your topContent to this:
<div id="topContent">
<div id="products" style="display: none;">
<h2>Test worked! - products </h2>
<p>this test just worked sooo hard!</p>
</div>
<div id="about" style="display: none;">
<h2>Test worked! - about </h2>
<p>this test just worked sooo hard!</p>
</div>
<div id="portfolio" style="display: none;">
<h2>Test worked! - Portfolio </h2>
<p>this test just worked sooo hard!</p>
</div>
</div>
Reasons:
Firstly, you need your ids to be like this: id="about" and not this: id="#about".
The id specified doesn't need a # in front of it. (Same as how class doesn't need a . when setting a tag with it)
The jQuery code I tested locally, so it should work.
Note:
You may want to automatically have some different content automatically displayed, because right now as it loads it is blank until you click one of the links.
Hope this helped!
Edit:
I suggest you change the code to this:
ids = [ "products", "about", "portfolio" ];
links = [ "Products", "About", "Portfolio" ];
$(function(){
$last = null;
$(".navList li a").click(function(){
New = "#" + ids[links.indexOf($(this).text())];
if ($last != null) $last.fadeOut(1000);
$last = $(New);
$(New).fadeIn(2000);
});
});
Because it will keep all the content constantly in the same place. For this to work, you'll need to change two more sections of your code:
<ul class="navList">
<li class="navItem">Products</li>
<li id="view-about" class="navItem">About</li>
<li class="navItem">Portfolio</li>
<li class="navItem">Contact</li>
</ul>
And:
<div id="topContent">
<div id="products" style="display: none; position: absolute">
<h2>Test worked! - products </h2>
<p>this test just worked sooo hard!</p>
</div>
<div id="about" style="display: none; position: absolute">
<h2>Test worked! - about </h2>
<p>this test just worked sooo hard!</p>
</div>
<div id="portfolio" style="display: none; position: absolute">
<h2>Test worked! - Portfolio </h2>
<p>this test just worked sooo hard!</p>
</div>
</div>
That last part was just my suggestion, but do whatever you need to.
Instead of doing this in your a.transition handler:
$("#topContent").fadeOut(1000);
do:
$("#topContent").children().fadeOut(1000);
The issue is that you're actually fading out the higher level item thus the children are no longer visible even if you fade them in.
I have 2 questions:
1) Since I have similar structure for the html contents and the only difference is that class title contents are different. I tried using $(div .title:contains("cat")) also
$(div .title).text()="cat")
2)How can I get the index of the accordion by just checking the $(div a) contents are required ones. I tried using $(div a).text()=="cat"
Check the codes here:
HTML1 contents
<div class="mod moduleselected" id="mod969">
<div class="content module moduleselect">
<div class="hd" ><div class="inner">
<div class="title">cat</div>
<ul class="terminallist"></ul>
<ul class="buttons">
<li class="help"></li>
<li class="show" ></li>
</ul>

<div class="mod moduleselected" id="mod969">

</div>
Accordian
<div id="dia">
<div id="dialog" title="Detailed FeedBack ">
<div id="accordion">
<h3>dog</h3>
<h3>cat</h3>
<h3>rat</h3>
</div>
</div>
</div>
Javascript
$('div .title').mouseover(function() {
if($("div a").text().indexOf("cat")!=-1)
{
$("#accordion").accordion("activate", 1);
}
$('div .title').mouseleave(function(){$("#accordion").accordion("activate", -1); });
});
Here is what I am trying to do with this javascript code. When I mouse over the cat contents I want the accordion with cat contents to open. And when I leave it to close the accordion selection.
When I hover my mouse over the html contents cat ,rat. It should side by side open the accordion button of those contents. Example: I hovered over rat (of html contents) I should see accordion rat open (or active i.e. contents visible).
Updated (see demo)
It sounds like you want something like this: when a content section is hovered over, find the title of that section, match its text against the text of the <a> elements in the accordion, and activate that section:
$(function() {
$("#accordion").accordion();
var links = $('#accordion a').map(function() {
return $(this).text().trim().toLowerCase();
}).toArray();
$('div.content').mouseover(function() {
var title = $(this).find('div.title').text().toLowerCase();
var index = links.indexOf(title);
if (index != -1) {
$("#accordion").accordion("activate", index);
}
});
});
P.S. jQuery does have a .hover() method for this as well.
It should be as succinct as the following (with potential minor tweaks):
$('.content .title').hover(function(e){
var index = this.textContent.split(/\W/)[1] - 1;
$("#accordion").accordion('activate', index);
});
Be careful with the HTML as this regular expression is overly simple in that it just grabs the last "word" which in the case of your example is a number. We subtract one to get a zero-based index. That will break if you add further text to the element.
