First and for most, I am new to web coding and more or less just teaching myself when I have free time... so I apologize if I make little sense.
I essentially have a simple javascript that allows me to have a prev and next button to move through multiple images. However I wanted to have multiple of these sets of "galleries" but in my case they interact with each other. I've attempted to contain each section (gallery, small text box, and the two buttons) but I've had no luck.
If you follow my link bellow you can see my issue... depending on the size of your screen you may only see one gallery, but you can see the each set of buttons affects each gallery.. This also for some reason adds "blank" images into the list of the image galleries.

Thanks in advanced!
This is my source code
<div class="section black" id="top_ten">
<div id="title"><h1>TOP TEN</h1></div>
<div id="image">
<div class="container">
<ol>
<li><img src="images/project5_1.jpg"></li>
<li><img src="images/project5_2.jpg"></li>
<li><img src="images/project5_3.jpg"></li>
</ol>
<div id="contentfooter">
<div id="footer">A publication and poster, which teaches guide lines to technical constraints. With any design job there comes rules and guidelines to follow in order to put out a proper project.</div>
<span class="button prevButton">–</span>
<span class="button nextButton">+</span>
</div>
</div>
</div>
</div>
This is my js
<script type="text/javascript" src="js/jquery-1.4.2.min.js"></script>
<script>
$(window).load(function(){
var pages = $('.container ol li'), current=0;
var currentPage,nextPage;
$('.button').click(function(){
currentPage= pages.eq(current);
if($(this).hasClass('prevButton'))
{
if (current <= 0)
current=pages.length-1;
else
current=current-1;
}
else
{
if (current >= pages.length-1)
current=0;
else
current=current+1;
}
nextPage = pages.eq(current);
currentPage.hide();
nextPage.show();
});
});
You have multiple elements with the same ID #container. Only one element can have an ID. Make it a class if you want to give it to multiple elements.
Now, when you select pages, you're selecting all of them.
var pages = $('#container ol li')
That would select every li inside and ol inside #container (it would be every container but it's an ID so that's causing you problems, too).
You know which button you clicked using $(this) so you can use .parent() to go up the DOM and find the container that contains that button and set of pages and only select that.

I have a menu on the site in two places. One is made by text, and the other by pictures. You can click on both.
I want that when you hover over a specific item in a text menu (for example, under number 2), the picture with the same number changes (for example, under 2).
Code for text menu:
<ul>
<li class="page_item">
Test 1
</li>
<li class="page_item">
Test 2
</li>
</ul>
Code for Pictures menu:
<div class="project__card project__card-design">
<div class="project__card-design-bigelem">
</div>
<div class="project__card-design-bigelem">
</div>
<div class="project__card-design-bigelem">
</div>
</div>

I will be grateful for any help!
Since I was looking for solutions that could identify the element with which number was highlighted. But so far I don’t even have ideas on how to do this.
All thanks in advance for any help!
If you like for this behaviour you can do this
hover: nav1 > imageNav1 ect...
You can get the index of the hover item and match that to the image nav item. Sorry for the markup, it's just to show you how you can implement it. You can also choose to do whatever after the matching is made in the mouseenter
$(".js-hover").on("mouseenter", function () {
const hoverIndex = $(this).index();
const $imageListItems = $(".image-list > li");
$imageListItems.removeClass("image-list__item--selected");
$imageListItems.eq(hoverIndex).addClass("image-list__item--selected");
});
.image-list__item--selected {
background-color: red;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<ul class="list">
<li class="js-hover">text</li>
<li class="js-hover">text</li>
<li class="js-hover">text</li>
<li class="js-hover">text</li>
</ul>
<ul class="image-list">
<li>image1</li>
<li>image2</li>
<li>image3</li>
<li>image4</li>
</ul>
Here's a solution with pure js, works for elements that are not parents using ids.
html
<li id="child1" onmouseenter="customHover(event)" onmouseleave="handlemouseleave(event)"></li>
<div id="parent1"> </div>
<li id="child2" onmouseenter="customHover(event)" onmouseleave="handlemouseleave(event)"></li>
<div id="parent2"> </div>
<li id="child3" onmouseenter="customHover(event)" onmouseleave="handlemouseleave(event)"></li>
<div id="parent3"> </div>
and heres the js
function customHover(e){
let id = e.target.id;
let idNumber = id.slice(id.length - 1);
document.getElementById(`parent${idNumber}`).style.border = '1px solid red';
}
function handleMouseLeave(e){
let id = e.target.id;
let idNumber = id.slice(id.length - 1);
document.getElementById(`parent${idNumber}`).style.border = 'unset';//or whatever you need to change the styles back to the original
}
there are many solutions , with an without using libraries. I think you may use some jquery if possible , and if not you should search for addeventlistener (the advanced way)
https://api.jquery.com/hover/
is a good example of doing what you are trying todo .
var pageitemcount=0;
$( ".page_item" ).hover(function() {
pageitemcount++;
$.post("/mypageitemcounter.php",{pageitemcount:pageitemcount});
$(this).parent().append( $( "<span>"+pageitemcount+"</span>" ) );
});
The above part is for php , still can be used in a plugin.
If you are in wordpress environment , you have to dig into how to write wp plugins also. Trying to achieve this in an environment , and then applying the same to your custom wp plugin is the way to go. Do not change the existing plugins, or themes if possible. This may cause headaches after an update.. In wp environment, writing a custom plugin is the way to go. You should tag your question as wp-plugin if possible.
I don't want to change HTML because I want to leave the display the way it is for default view and want to move them in second view. I want to know how I can dynamically order the class of a div.
I want to do this via button click. I have adEventListener() for 'click' where I am doing something and the move logic would go inside this event listener.
I understand that I can get these divs, remove from their parents and place it where I want. But I do not know how to do these for each of them since I have multiple lis. I am struggling with the loop so that I can do these for each li. I need to do this using pure JS and not jQuery.
<ul>
<li>
<div>
<div class="a">
<div class="b">
<a class="c">
<div class="d"></div>
<div class="e">
<div class="f"></div> // this is the first item that I want to move
</div>
<div class="g"></div> // this is the second item that I want to move
</a>
</div>
<div class= "h"></div> // I want above mentioned divs to be before this div
</div>
</div>
</li>
//There are multiples lis
<li></li>
Assuming you would like to do this on load of the page, you could solve your problem with the following JQuery DOM manipulations:
$(document).ready(function(){
$("ul .a").each(function(index, element){
$current_div_a = $(element);
$div_h = $current_div_a.find(".h");
$div_f = $current_div_a.find(".f");
$div_f.clone().insertBefore($div_h);
$div_f.remove();
$div_g = $current_div_a.find(".g");
$div_g.clone().insertBefore($div_h);
$div_g.remove();
})
});
You can test it out on this demo.
I strongly advise against this way of doing it though. I guess it's also the reason why your question got some downvotes too. Just modifying your HTML keeps your code clean, maintainable and clearer for anyone else starting to work on your project. Keeping backwards compatibility for your code as much as possible will cause maintainability problems later.
I ended up using
var list = document.querySelectorAll("ul li");
for (var item of list) {
let fClass = item.querySelector(".f");
fClass.parentNode.removeChild(fClass);
let parentOfFirstChildAfterWhichIwantMyF = item.querySelector(//selector for parentOfFirstChildAfterWhichIwantMyF);
parentOfFirstChildAfterWhichIwantMyF.insertAdjacentElement("beforeend", fClass);
}
My issue involves multiple DIVs that display:block or display:none each with their own anchor tag. The main problem is that I have recommissioned the JS code that runs this feature without completely understanding it. All I need is a way to toggle all of the DIVs with a single "Show All/Hide All" link. I cannot wrap my head around it.
I have tried absolutely everything that my exceptionally limited grasp will allow - which consists mostly of swinging my arms in the dark and hoping I accidently build a miracle. Since that hasn't worked I am shamefully seeking help.
The only thing that makes this question unique are all the variables with this specific issue -
An (almost) working example can be found at: www.robertmeans.com/menu.htm
The JS code:
imageX01='plus';
imageX02='plusEven';
function toggleOdd(ee){
imgX="imagePM"+ee;
divX="div"+ee;
imageX="imageX"+ee;
divLink="divHref"+ee;
imageXval=eval("imageX"+ee);
element = document.getElementById(divX).style;
if (element.display=='none') {element.display='block';}
else {element.display='none';}
if (imageXval=='plus') {document.getElementById(imgX).src='_images/minus.gif';eval("imageX"+ee+"='minus';");document.getElementById(divLink).title='Hide Content';}
else {document.getElementById(imgX).src='_images/plus.gif';eval("imageX"+ee+"='plus';");document.getElementById(divLink).title='Show Content';}
}
function toggleEven(ee){
imgX="imagePM"+ee;
divX="div"+ee;
imageX="imageX"+ee;
divLink="divHref"+ee;
imageXval=eval("imageX"+ee);
element = document.getElementById(divX).style;
if (element.display=='none') {element.display='block';}
else {element.display='none';}
if (imageXval=='plusEven') {document.getElementById(imgX).src='_images/minusEven.gif';eval("imageX"+ee+"='minusEven';");document.getElementById(divLink).title='Hide Content';}
else {document.getElementById(imgX).src='_images/plusEven.gif';eval("imageX"+ee+"='plusEven';");document.getElementById(divLink).title='Show Content';}
}
The HTML
<div id="task_item01">
<img src="_images/plus.gif" alt="" name="imagePM01" width="33" height="33" border="0" class="task_itemPlusImage" id="imagePM01" />
Div #1
</div>
<div style="display:none;" id="div01">
Content 1
</div>
<!-- ******************************** Item 1 End **************************** -->
<!-- ******************************** Item 2 Start ************************** -->
<div id="task_item02">
<img src="_images/plusEven.gif" alt="" name="imagePM01" width="33" height="33" border="0" class="task_itemPlusImage" id="imagePM02" />
Div #2
</div>
<div style="display:none;" id="div02">
Content 2
</div>
I have spent countless hours trying to work this out on my own. Any help is deeply appreciated.
Ok first of all, it seems like way too much code to me... you can do this very easily by using jQuery. I have made an example here: http://jsfiddle.net/Nr2f6/4/
Here is some simple html to help you better understand what is being done:
<div id="item-1"><span class="plus"></span>Open these items</div>
<div class="contents" data-rel="item-1">
I have superb items in this div... the world is about to understand just how awesome I am!
</div>
<div id="item-2"><span class="plus"></span>Open these other items</div>
<div class="contents" data-rel="item-2">
I have amazing contents in this div. I want to show them to the world!
</div>
as you can see above, there is no inline css. All the styling (display: none) should be placed separately, to not conflict with what you are trying to do. So simply place it in a separate css file.Then run this code:
$("div[id^=item]").click(function(){
var reference2open = $(this).attr("id");
//get the data-rel attribute associated
$("div[data-rel='"+reference2open+"']").slideToggle();
$("span",this).toggleClass('minus');
});
$("#all").click(function(){
if($(this).hasClass('close')){
$("div[data-rel^=item]").slideUp();
$("div[id^=item] span").removeClass('minus');
$("#all").removeClass('close');
$("#all").html('open them all');
}else{
//open and close them all by clicking
$("div[data-rel^=item]").each(function(){
if($(this).is(':hidden')){
$(this).slideDown();
$("div[id^=item] span").addClass('minus');
$("#all").html('close them all');
}
});
//change the button to close
$("#all").addClass('close');
}
//$("div[id^=item] span").toggleClass('minus');
});
****ADDED IN THE TOGGLE PLUS AND MINUS SIGNS USING CSS****
.plus{
background: url(http://www.robertmeans.com/offsite_files/code_help/_images/plus.gif);
width: 33px;
height: 33px;
display: inline-block;
}
.minus{
background: url(http://www.robertmeans.com/offsite_files/code_help/_images/minus.gif);
width: 33px;
height: 33px;
display: inline-block;
}
Do not forget to include your jQuery file! Hope this helps :)
Just wanted to add in some details for better understanding:
div[id^=item]: Is saying whenever a div is clicked that has an id that starts with (^=) item, run the code.
$("div[data-rel='"+reference2open+"']").slideToggle(): is saying take the id from the div that was clicked and find the content box where with the same name but in the data-rel attribute. The slide it down, if it is already down, slide it back up (toggle). You do not have to use a slide effect, I just thought it was more fun!
Then last but not least, the function you were looking for: How to open them all at once. Again we are using the (^=) to find all of the divs.
$("div[data-rel^=item").slideToggle();: So here we are saying to jQuery, hey toggle all the boxes that have a data-rel attribute that starts with (^=) item.
This last part is pretty neat, because you can create many instances of the item-? boxes and this code will work for any number of them. You can also add the same code to a different div, like even and odd, and toggle all the even and all the odd elements accordingly.
You could assign a specific class to all the things you want to toggle, then loop through all of them with a toggle function.
First of all, I know that this question has been answered on this site numerous times and that is the main problem here. I am spoiled for choice in the answers and have been searching for a few hours, not finding anything directly similar. There must be plenty of ways to do this, but what I have right now is closest to what I want.
I have this for my code at the moment, for some reason the fiddle won't work, while it works fine in my code, must have missed something.
http://jsfiddle.net/PVLMX/
Html:
<div id="wrap">
<p>This text is visible, but there is more.<br/><br/>See more >>
</p>
<div id="example" class="more">
<p>Congratulations! You've found the magic hidden text! Clicking the link below
will hide this content again.</p>
<p><a href="#" id="example-hide" class="hideLink"
onclick="showHide('example');return false;">Hide this content >></a></p>
</div>
</div>
Javascript:
function showHide(shID) {
if (document.getElementById(shID)) {
if (document.getElementById(shID+'-show').style.display != 'none') {
document.getElementById(shID+'-show').style.display = 'none';
document.getElementById(shID).style.display = 'block';
}
else {
document.getElementById(shID+'-show').style.display = 'inline';
document.getElementById(shID).style.display = 'none';
}
}
}
I need to be able to call the function for each new "Read More" on the page. At the moment, the first "See More" is always the target of the javascript, and I am not sure how to call this function for other links on the page.
In HTML, each id="" must be a unique identifier, you can't put two id="example" so you need id="example" and id="example2" and so on.
Working jsfiddle: http://jsfiddle.net/PVLMX/2/
<div id="wrap">
<p>This text is visible, but there is more.<a href="#" id="example2-show"
class="showLink" onclick="showHide('example2');return false;"><br/><br/>See more >></a>
</p>
<div id="example2" class="more">
<p>This text was hidden, now you see it</p>
<p><a href="#" id="example2-hide" class="hideLink"
onclick="showHide('example2');return false;">Hide this content >></a></p>
</div>
</div>
What I changed:
every id="example.. to id="example2... in the second div.
load the script in "No wrap - in head" mode (jsfiddle left option)
In your fiddle you need to select the no wrap in <head> option. Your code works fine.
http://jsfiddle.net/uND9H/
Aslo you can't have duplicate id's
if you want to generalise this, there is a much easier way in jquery ie by using class you can bind click events and generalise them using class names. Here is an example , Check it out
$('.showLink').bind('click',function(e){
var obj = $(this).attr('id');
var name = obj.replace("-show","-hidden");
$('#'+name).css('display', 'inline-block');
});
$('.hideLink').bind('click',function(e){
var obj = $(this).attr('id');
var name = obj.replace("-hide","-hidden");
$('#'+name).css('display', 'none');
});
http://jsfiddle.net/AmarnathRShenoy/AMf8y/
You can use class names multiple times and you must always remeber that id can never be duplicated
Actually you can do it with jquery and much easier than you think
Jquery as follows:
$more = $('.more');
$('.showLink').click(function(e){
e.preventDefault();
$more.show();
})
$('.hideLink').click(function(e){
e.preventDefault();
$more.hide();
})
Also add a css style to display:none on .more class.
you can make it look a little nicer with slideToggle()
Here is a fiddle: http://jsfiddle.net/up36g/
I'm working on a js script which will show / hide multiple divs based on css class, seemingly pretty simple. I set out to find an example of this and found something close in the article linked below. I used the code in the following link as a starting point.
Show/hide multiple divs using JavaScript
In my modified code (shown below) I am able to hide all (which is errant) and show all (which works correctly. I'm not sure why its not targeting the CSS class "red, green or blue" correctly. If I hard one of the class names in the script it works as expected, so I'm fairly certain I'm having an issue in the way I'm referencing the css targets themselves.
I am able to hide all and show all, yet I'm having difficulty showing only the selected class.
Here is the jsFiddle I'm working with: http://jsfiddle.net/juicycreative/WHpXz/4/
My code is below.
JavaScript
$('.categories li a').click(function () {
$('.marker').hide();
$((this).attr('target')).show();
});
$('#cat-show').click(function () {
$('.marker').show();
});

</ul>

</div>
Thanks in advance for any responses.
$((this).attr('target')).show();
This is syntactically incorrect. It should be $($(this).attr('target'))
However that's no good either because this is the anchor element that does not have the target. Use $(this).closest('li').attr('target') (or add the target to the <a>).
This is also semantically incorrect as that would interpolate to $("red") which would try to look for a <red> element.
$("." + $(this).closest('li').attr('target'))
http://jsfiddle.net/WHpXz/5/
You are almost there. This is the line that needs tweaking: $((this).attr('target')).show();
$(this) actually refers to the current anchor tag that was clicked. Since the anchor tag doesn't have the target attribute, you need to go up to the parent.
From there, you can get the target and add the '.' to the color to use as a selector.
var catToShow = $(this).parent().attr('target');
$('.' + catToShow).show();
I've edited your fiddle. Give it a shot.
