Creating navigational pages with jquery - javascript

I actually didn't really know how to phrase the question title, but here is the description. Suppose I'm using jQuery to show/hide uls that are stacked on top of each other (absolutely positioned). For example:
<ul id="one">
<li>blah</li>
<li>blah2</li>
</ul>
<ul id="two">
<li>blah</li>
<li>blah2</li>
</ul>
I have a controller button, that when pressed, simply changes the z-index of these uls. The controller button is literally just:
My button
With jQuery code that does: (I'm using the jQuery cycle plugin)
$('#mybutton').click(function() {
// check which ul is currently shown
// change z-index, so that the next ul is to be shown
});
THE QUESTION:
In my site, I have several pages that I would like to point to the second ul, so that when clicked, it'll bring them to the page with all of the uls, but only the second one will be shown. It would be the same if the person went to the page, had the default first ul shown, and then clicked "next" to proceed to the next ul. I am simply wondering if it's possible to avoid pressing "next", and just bring the user directly to the page and have the second ul shown.

I think you can use the hash-tag from the URL. You can then write an if statement like this:
if(location.hash === "#2"){
$("#one").hide();
}else{
$("#two").hide();
}
Or directly as a copy and paste example:
<html>
<script src="http:////ajax.googleapis.com/ajax/libs/jquery/1.8.1/jquery.min.js"></script>
<script>
$(function(){
if(location.hash === "#2"){
$("#one").hide();
}else{
$("#two").hide();
}
$('#mybutton').click(function(e) {
$("ul").toggle(); //quick n dirty! only works with 2 lists :)
e.preventDefault();
});
});
</script>
<body>
My button
<ul id="one">
<li>First Item!</li>
<li>blah</li>
<li>blah2</li>
</ul>
<ul id="two">
<li>Second Item!</li>
<li>blah</li>
<li>blah2</li>
</ul>
To second page (you might have to refresh, notice the #2 at the end of the url!)
​</body>
</html>
Also notice I've inserted a e.preventDefault(); at #mybutton's click listener to prevent the URL changing back on clicking.

If I am understanding you correctly, perhaps you can accomplish this via a page wrap with a unique id per page? You can swap the id out with JS or server side logic, depending on what you're trying to do.
<div id="page-one">
<ul id="one">
<li>blah</li>
<li>blah2</li>
</ul>
<ul id="two">
<li>blah</li>
<li>blah2</li>
</ul>
</div>
then your css will be #page-one #one { display:block }; #page-two #one { display : none }; etc.

show() function doesn't seem to work as expected

I am trying to create a webpage with a menu on the left side and a content area on the right side. Mockup image below to give you an idea:
I am using jQuery UI to try to accomplish this. The goal is to have the content area on the right side to be set based on the menu item selected on the left. The area will always be a tabbed layout, but the content and amount of tabs will be different for each of the item selected from the left menu. Eventually, I want to integrate this into an ASP.NET MVC 5 app to include user authorization and roles affecting what menu items and tabs will be visible based on the logged in user. But for now, I am simply trying to get the tab menu to show up based on what I click on the left menu, and to show it specifically upon clicking one specific item. For the others, it will hide it again (I have not tried to implement the re-hiding yet, and that is not part of this question; I just want to get the initial show() to work).
So right now my approach is to hide the tabs on page ready, then use a function to display it when clicked, using the jQuery show() function. However, this doesn't work (tried in firefox and IE).
My attempt is at: https://jsfiddle.net/3mo28z1t/5/
In the fiddle, in the javascript section, if you change the "hide" to "show"
$("#tabsuseradmin").hide();
you will see the tabs menu, in case you want to get an idea of the layout before trying to fix the issue.
Specifically, I want the action of clicking on "Left menu item 3" to show the tabs.
Thank you.
I cleaned your fiddle up so that your scripts/css were in external resources. You must first define the target and then call the function with the target - you haven't targeted the individual tabs(i haven't done this for you either, i'm just pointing it out) Also you can't use show as a function name, as its reserved.
What i did do is create a toggle on the #leftmenu>li - see fiddle
$(function() {
$("#tabsuseradmin").tabs();
$("#leftmenu").menu();
});
$('#leftmenu>li').on('click', function(){
$("#tabsuseradmin").toggle();
});
$(function showTab(target) {
document.getElementById(target).show();
});
$(function hideTab(target) {
document.getElementById(target).hide();
});
#leftmenu {
display: inline-block;
}
#tabsuseradmin {
display: inline-block;
margin-right: 10px;
}
<link href="https://code.jquery.com/ui/1.11.4/themes/smoothness/jquery-ui.css" rel="stylesheet"/>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<script src="https://code.jquery.com/ui/1.11.4/jquery-ui.js"></script>
<body>
<ul id="leftmenu">
<li>Left menu item 1</li>
<li>Left menu item 2</li>
<li>Left menu item 3</li>
<li>Left menu item 4</li>
</ul>
<div id="tabsuseradmin">
<ul>
<li>Tab first</li>
<li>Tab second</li>
<li>Tab third</li>
</ul>
<div id="tabs-1">
<p>Tab 1</p>
</div>
<div id="tabs-2">
<p>Tab 2</p>
</div>
<div id="tabs-3">
<p>Tab 3</p>
</div>
</div>
</body>
<li id="clicker" onclick="show('tabsuseradmin')">Left menu item 3</li>
$(document).ready(
function(){
$("#clicker").click(function () {
$("#tabsuseradmin").show();
});
});
Updated Fiddle
There is an error in your code. If you check console, it specifically says - show is not defined. Show & hide are methods provided by jQuery. They are not the same in javascript.
In your example you are using document.getElementById(target).show();, but .show is a jQuery method
you should use something like :
$(document.getElementById(target)).show();
$('#'+target).show();
You can also declare your event handler differently to avoid the problem seen in jsfiddle (that show is not defined), see my updated jsfiddle for that

Why is the jQuery function showHide() undefined?

I'm really new at trying to use jQuery, so please forgive me for asking what is likely a simple question. Perhaps it isn't even related to jQuery, but anyway, here's the scenario. I'm trying to put in a hidden div which I only want to show up when the user hovers their mouse over the Learner's anchor tag on the page. I've started with only one anchor tag, to get it working first before implementing the rest of them. I've downloaded a jQuery library and included a reference to it, so here's some of what I've got in my page's head section:
<script src="js/jquery-1.11.1.js" type="text/javascript" ></script>
<style type="text/css">
#navcontainer ul { list-style-type: none; }
#navcontainer ul li { display: inline; }
#navcontainer ul li a
{
text-decoration:none;
padding: .2em 1em;
}
</style>
Next I've defined an unordered list, using the styling above to make it horizontal, and I've got a hidden div after it, which I want to show when the user moves their mouse over the first anchor in the unordered list. Here's the relevant HTML from within the body tag:
<body>
<div id="navcontainer">
<ul>
<li>Home</li>
<li>Learners</li>
<li>Teachers</li>
<li>Businesses</li>
<li>Contact Us</li>
</ul>
<div id="dropdown1" style="visibility:hidden;">
<ul>
<li>Description A</li>
<li>Description B</li>
<li>Description C</li>
</ul>
</div>
<!-- other HTML code -->
</body>
However, when I run this from within the browser (IE11) nothing happens. Using the F12 web developers tools built into IE11 I learn that it giving an error of "showHide is undefined". Why is it doing that? The showHide() function is most certainly in the jquery-1-11.1.js file, which most certainly is in my js folder. What have I done wrong, or failed to take into account?
jQuery works kinda different than that. You have to make it look like this:
$("#dropdown1").toggle()
You better make a javascript file and separate the JS from the HTML:
HTML:
<body>
<div id="navcontainer">
<ul>
<li>Home</li>
<li>Learners</li>
<li>Teachers</li>
<li>Businesses</li>
<li>Contact Us</li>
</ul>
<div id="dropdown1" style="visibility:hidden;">
<ul>
<li>Description A</li>
<li>Description B</li>
<li>Description C</li>
</ul>
</div>
<!-- other HTML code -->
</body>
The JS
$(function(){
$("#navcontainer li a").click(function(){
if( this.href.indexOf("#") != -1 ) {
$( $(this).attr("href") ).toggle(); // $( "#container1" )
}
});
});
What this does is on the navcontainer li click, we make a handler, which does something if it contains a #. Then we select that element #container1 which is in the href, also is the selector for the element which we want to show. And we toggle that element.
There is no such function as showHide you could use toggle() or show() or hide()
in you current scenario uou would couple them with $(this). or your chosen selector.
As an example of targetting a particular element with jQuery we have added the class hover-learners and target it with the selector below.
HTML:
<div id="navcontainer">
<ul>
<li>Home
</li>
<li>Learners
</li>
<li>Teachers
</li>
<li>Businesses
</li>
<li>Contact Us
</li>
</ul>
<div id="dropdown1">
<ul>
<li>Description A
</li>
<li>Description B
</li>
<li>Description C
</li>
</ul>
</div>
Add the below javascript as a file or within <script type="text/javascript"> code here</script> after including your jQuery library file.
Javascript:
// wrap everything in jQuery's ready function to make sure the page has fully loaded before executing the javascript
$(document).ready(function () {
//select learners and apply mouseover event
$('.hover-learners').on('mouseover', function () {
$('#dropdown1').show();
});
//select learners and apply mouseout event
$('.hover-learners').on('mouseout', function () {
$('#dropdown1').hide();
});
});
Also since the show and hide methods manipulate the display CSS property I have added
CSS:
#dropdown1 {
display:none;
}
and remove the inline style="visibility:hidden" from the #dropdown1

Navigation with onClick / Javascript not working

I have created a menu for my website which you can find here:
http://jsfiddle.net/nq9Nt/9/
When click a category on the menu it opens that category on my main navigation?
Is something conflicting or have I placed my Javascript in the wrong place?
So I want to be able to click a category and show the sub-categories but it just won't work. Also is there a way to keep open the category you clicked after you change page?
Thank you
<ul class="nav">
<li>Category 1
</li>
<li class="drop">Category 2
<ul id="sub1">
<li>Item
</li>
<li>Item
</li>
</ul>
</li>
<li class="drop">Category 3
<ul id="sub1">
<li>Sticker
</li>
<li>Sticker
</li>
</ul>
</li>
<li>Category 4
<ul id="sub1">
<li> Mural
</li>
<li>Mural
</li>
</ul>
</li>
$(".drop")
.on('click', function () {
$(this).find('ul').toggle();
})
Actually at least on jsfriddle animation works and if you replace href of your anchors from '#' to a real url you will be redirected to another page, so first make sure that you've attached jquery library in head of the document (since you use it in your script), then move your script to the bottom of the page, right before tag 'body' closes.
About keeping the state of the opened categories after refresh - usually it is made on server side while generating template by adding class, for example 'active', to current link and then, using css, corresponding category (or a hierarchy of categories) is set to be opened (li.active ul {display: block;} for example). Well, actually you could do the same trick - use js to find out current url with the help of window.location.pathname value and match it with a href value of your navigation links and then assign class 'active' to the found element (or its parent, it is up to your css)
You can add a class drop to li in 4th Category, so it will work as others. And remove that onclick if you don't plan to use it.
http://jsfiddle.net/nq9Nt/10/
Here the example,
jsbin
You have gave the anchor href with #, So It reloads the page. And also you have gave the onclick method, But it doesn't there.

JS Toggle hides ALL toggled divs -- makes page non-functioning

Sorry if this is a silly question, I'm very new to JS/JQuery and don't know if there's a simple answer to my problem.
I have two toggling divs set up more or less like the following (this is the stripped-down version):
<div id="top-story-panel">
<div id="story-toggle">
<ul>
<li id="top-stories">
Top Stories
</li>
<li id="toc">
All Stories
</li>
</ul>
</div>
</div>
<div id="toc-panel">
<div id="story-toggle">
<ul>
<li id="top-stories">
Top Stories
</li>
<li id="toc">
All Stories
</li>
</ul>
</div>
</div>
With this function, the two divs toggle back and forth without a hitch, but if you click on one of the toggles ("top stories"/"all stories", respectively) and then click it AGAIN it hides the div it just showed and... can't find anything else to replace it with. Both divs are hidden now and there's no way for the user to interact with either div.
jQuery(function($) {
var $contentPanel= $('#top-stories-panel, #toc-panel')
$toggle= $("#top-stories, #toc");
$toggle.on('click', function(e) {
var $id;
e.preventDefault();
$icons.removeClass('hidden');
$id=$('#'+this.id+'-panel'); //get menu id
$contentPanel.fadeOut(10);
if(! $id.is(':visible')) {
$id.fadeIn(450)
preloadImages: 'all';
$(this).addClass('hidden');
}
});
});
I'm assuming that if I place the toggles outside of their respective divs, I won't have this problem -- but is there a code workaround for the toggle to stay within the div?
Thanks so much for all of your help ;_;

if mouse on hover of div then display menu

I have the following menu which cascades on hover but i need to add some conditional checks like if the mouse is on hover on the div then keep the menu sliding down.
Also if the mouse is hovered on the LI then check them menu down.
As you can see it just slides down and back up once you leave the "div".
Im stuck... and have tried for hours searching for if statements etc, i just cant get the syntax correct.
my example
Here is a working example
HTML
<div id="leftWrap">
<div id='accordion'>
<ul>
<li><div>Absorption</div>
<ul style="display: none;">
<li>Accessories</a>
<ul style="display: none;">
<li>AA500AFG</li>
<li>AA500F</li>
<li>AA500G</li>
<li>AA990F</li>
</ul>
</li>
<li>Consumables</li>
<li>Products</li>
</ul>
</li>
<li><div>Fluorescence</div>
<ul style="display: none;">
<li>Accessories</li>
<li>Consumables</li>
<li>Products</li>
</ul>
</li>
</ul>
</div>
</div>
Javascript/JQuery
jQuery(document).ready(function() {
$('#accordion ul > li').hover(function() {
$(this).children("ul").slideToggle('slow');
});
});
If you ask me, it gets really messy when you use mousehover/mouseenter for such things. I'd prefer using a click event after the first hover or something, this way the user won't get annoyed by all that movement.
jQuery(document).ready(function() {
$('#accordion ul:first-child > li').hover(function() {
$(this).children("ul").slideToggle('slow');
});
$('#accordion ul:not(:first-child) > li').click(function(){
$(this).children("ul").slideToggle('slow');
});
});
Make it a child of the <div>, then it won't cancel the event when you leave it.
Also I should note that it's more semantic to make a navigation out of nested lists (such as
Category ItemItem
<ul>
<li>Category
<ul>
<li>Item</li>
<li>Item</li>
</ul>
</li>
</ul>
I tried to fiddle in your fiddle, but the markup and css are a lot confusing.
As Rikudo said, you should make the div, its child its much easier to do it that way. I have created a simplest accordion skeleton. You can see it here.
It does everything you want. However for the customizations and others things, I will leave it up to you.
http://jsfiddle.net/dttdB/13/
You had attached hover to the heading div when the mouse leaves that, the hover effect is lost.
