Javascript to show hidden div overlay with close button on clicks - javascript

I am after a little help - I'm not a great programmer, and can usually find the answers to my questions with googling, but not this time!
I am trying to produce a specific effect on a webpage, and am struggling to find some basic JS I can modify/tweak to do what I need.
I am going to put a panel of 10 images, in two rows of five, across a webpage. Each image will have a 'Name' above it, and a 'Job Title' below it. When the image is clicked on, I'd like the (relevant) hidden div to display, over the top of all the images - i.e. with the top left corner matching the top left corner of the first image. The div will be a pre-set width.
In the top corner of each div I want a simple close button.
So, what I am trying to produce is code that's scalable - i.e. in theory it shouldn't matter how many images there are as long as I get the structure right, when you click on the image, it 'shows' the correct hidden div.
We already load jQuery on to the webpage, so using that would be no problem.
Any advice/links to snippets/pointers would be appreciated!

This is quite simply achieved with jQuery and jQueryUI.
For brevity I have only included 5 images here http://jsfiddle.net/8kefF/2/
HTML:
<div>
<div class="clickThisPicture" data-content-id="1">
<img src="http://placehold.it/350x150" />
</div>
<div class="clickThisPicture" data-content-id="2">
<img src="http://placehold.it/350x150" />
</div>
<div class="clickThisPicture" data-content-id="3">
<img src="http://placehold.it/350x150" />
</div>
<div class="clickThisPicture" data-content-id="4">
<img src="http://placehold.it/350x150" />
</div>
<div class="clickThisPicture" data-content-id="5">
<img src="http://placehold.it/350x150" />
</div>
</div>
<div class="hiddenContent" data-content-id="1">Hidden content 1</div>
<div class="hiddenContent" data-content-id="2">Hidden content 2</div>
<div class="hiddenContent" data-content-id="3">Hidden content 3</div>
<div class="hiddenContent" data-content-id="4">Hidden content 4</div>
<div class="hiddenContent" data-content-id="5">Hidden content 5</div>
CSS:
.hiddenContent {
display:none;
}
.clickThisPicture {
float:left;
border:1px solid #000;
}
Javascript:
$(document).ready(function () {
$('.clickThisPicture').on('click', function (event) {
var contentId = $(this).data('content-id');
$(".hiddenContent[data-content-id='" + contentId + "']").dialog({
modal: true,
resizable: false,
draggable: false,
closeOnEscape: false,
dialogClass: "no-close",
buttons: {
"Close": function () {
$(this).dialog("destroy");
}
}
});
});
});
EDIT: I updated the code to hide the default close button so as to destroy the element each time as the OP asked for scalability so having potentially 100's/1000's of extra elements in the DOM would lead to memory issues. eventually.

If I understand correctly, this jQuery plugin will help You: plainOverlay

Trying to make different text appear below 3 aligned images on hover

First things first, here is my example :
https://jsfiddle.net/y532ouzj/33/
HTML:
<div id="image" class="item">
<a ><img src="http://www.topring.com/images/carre_download_cat_ENG.jpg"></a>
</div>
<div id="text" class="show">Text 1</div>
<div id="image" class="item">
<a ><img src="http://www.topring.com/images/carre_download_cat_ENG.jpg"></a>
</div>
<div id="text" class="show">Text 2</div>
<div id="image" class="item">
<a ><img src="http://www.topring.com/images/carre_download_cat_ENG.jpg"></a>
</div>
<div id="text" class="show">Text 3</div>
CSS:
.item {
/* To correctly align image, regardless of content height: */
vertical-align: top;
display: inline-block;
/* To horizontally center images and caption */
text-align: center;
/* The width of the container also implies margin around the images. */
width: 190px;
}
.show {
display: none;
}
.item:hover + .show {
display: block;
}
JAVASCRIPT :
$('#image').hover(function() {
$('#text').show();
}, function() {
$('#text').hide();
});
It almost works but I must be forgetting a little something since my 3 pictures aren't staying where I want them to once I start hovering that mouse. So if you don't hover over the pictures, everything is good, 3 pics aligned. Hover over pic #1 or 2, text goes exactly where I want it, but why does my pic 3 and pic 2 also move down ? Hover over pic #3, everything works the way it should.
You have multiple problems with this. First of all, ids can only be used once. Change them to classes, and you should be fine. Second, move the divs inside of the image div, and it will only show the one that you would like to. Updated javascript and html follows:
fiddle: https://jsfiddle.net/y532ouzj/34/
HTML
<div class="image item">
<a><img src="http://www.topring.com/images/carre_download_cat_ENG.jpg"></a>
<div class="text show">Text 1</div>
</div>
<div class="image item">
<a><img src="http://www.topring.com/images/carre_download_cat_ENG.jpg"></a>
<div class="text show">Text 2</div>
</div>
<div class=" image item">
<a><img src="http://www.topring.com/images/carre_download_cat_ENG.jpg"></a>
<div class="text show">Text 3</div>
</div>
Javascript
$('.image').hover(function () {
var that = $(this);
that.find('.text').show();
}, function () {
var that = $(this);
that.find('.text').hide();
});
First of all, java and javascript aren't the same thing; they're two separate languages.
Second, in HTML, it's bad form (and possibly dead wrong) to use the same id for multiple elements on a page. the value of each id attribute should be unique.
Finally, the answer in HTML and jQuery:
https://jsfiddle.net/y532ouzj/36/
The HTML now contains just one text. It will be modified for each case
<div id="image_1" class="item">
<a >
<img src="http://www.topring.com/images/carre_download_cat_ENG.jpg" /> </a>
</div>
<div id="image_2" class="item">
<a >
<img src="http://www.topring.com/images/carre_download_cat_ENG.jpg" />
</a>
</div>
<div id="image_3" class="item">
<a >
<img src="http://www.topring.com/images/carre_download_cat_ENG.jpg" />
</a>
</div>
<div id="text" class="show">
Text
</div>
The javascript now modifies and reveals the text based on whichever image triggers the event.
$('#image_1').hover(function() {
$('#text').html("Text 1");
$('#text').show();
}, function() {
$('#text').hide();
});
$('#image_2').hover(function() {
$('#text').html("Text 2");
$('#text').show();
}, function() {
$('#text').hide();
});
$('#image_3').hover(function() {
$('#text').html("Text 3");
$('#text').show();
}, function() {
$('#text').hide();
});
I'm going to make a suggestion instead of answering the direct question. Instead of overcomplicating this, I suggest you used the Title attribute.
<div class="image"><a><img src="" title="Text 1" /></a></div>
Most browsers will know what to do with this. Some older browsers may give varying quality of interpreting the attribute, but this is the easiest way to do what you are trying to accomplish.

onClick image, display div content

I am very new to javascript but i wanted to know how to do something in it. Basically i have 3 image buttons. I want to know how i can make it so when you click the first button a div shows up, then when you click the next button the div that is present disappears and the next div shows up for button two in its place. By divs i mean any content that i put inside of it. Just like the tabs on a website, when you click one you get a page. Then when you click the next tab the previous page disappears and the next page is shown. Instead of pages these would be divs.
Any advice would be greatly appreciated.
Here is the simple solution for hide and show related div's
Check the link for solution : http://jsfiddle.net/silpa/rny2wb5z/34/
HTML:
<img src="http://i.stack.imgur.com/JHoSf.gif?s=128&g=1" data-id="divId1"/>
<img src="http://i.stack.imgur.com/JHoSf.gif?s=128&g=1" data-id="divId2"/>
<img src="http://i.stack.imgur.com/JHoSf.gif?s=128&g=1" data-id="divId3"/>
<div id="divId1" class="hideDivs">Div 1</div>
<div id="divId2" class="hideDivs">Div 2</div>
<div id="divId3" class="hideDivs">Div 3</div>
jQuery:
$("img").on('click',function(){
var hello = $(this).attr('data-id');
$('.hideDivs').hide();
$('#'+hello).show();
});
CSS:
.hideDivs{
display:none;
}
Assign IDs to the divs, then set their visibility with a function. You can call this function with the onClick attribute of the image button.
Javascript:
function changePage(newPageId) {
//hide all pages
document.getElementsByClassName("selectablePages").style.display = 'none';
//show page we want to see
document.getElementById(newPageId).style.display = 'block';
}
Html:
<img src="p1.gif" alt="page1" onclick="changePage('page1')" />
<img src="p2.gif" alt="page2" onclick="changePage('page2')" />
<img src="p3.gif" alt="page3" onclick="changePage('page3')" />
<div id="page1" class="selectablePage">asdasdasd</div>
<div id="page2" class="selectablePage">jghjghjghj</div>
<div id="page3" class="selectablePage">utytyutyuty</div>

JavaScript/jQuery guidance needed

Today I am building my self a vertical navigation menu and I'm wondering how I would go about build a particular feature I was thinking of.
Here is the coding behind my buttons:
html:
<div class="button"><a href="#">
<img src="../images/article.png" />
<p>Articles</p></a>
</div>
<div class="button"><a href="#">
<img src="../images/leaderboards.png" />
<p>Leaderboards</p></a>
</div>
<div class="button"><a href="#">
<img src="../images/events.png" />
<p>Events</p></a>
</div>
<div class="button"><a href="#">
<img src="../images/search.png" />
<p>Search</p></a>
</div>
<div class="button"><a href="#">
<img src="../images/other.png" />
<p>Other/Tools</p></a>
</div>
css:
.button{
border-left:10px solid #e5dad6;
padding-left:5px;
margin-bottom:20px;
width:120px;
height:120px;
text-align:center;
}
My Goal:
Now my goal is to change the image of the relevant buttons when a user hovers over the whole div (button div), now of course I can do this by adding a hover state in css, but that's not what I want to do, because I don't want to just change that particular div.
What I want:
I want it so I can basically say = if .button is being hovered over, then change the img src of something else on the page, NOT change something related to the element being hovered over.
Do something like this with jQuery:
$(document).ready(function() {
var oldSrc = $('.myNewImage').attr('src');
$('.button').hover(function() {
//on hover of your element
$('.myNewImage').attr('src','http://mynewimagesrc.com');
}, function() {
//when the cursor leaves your element
$('.myNewImage').attr('src', oldSrc);
});
});
You'll have to switch out the .myNewImage, class for the actual class of the image on your page but that should work for what you're asking. It also assigned the original source of your image so that you can always return the element back to it.
you may want to check .hover() for jQuery
You can do what you want really easy with jquery.
<div class="button" id="article_button"><a href="#">
<img src="../images/article.png"/>
<p>Articles</p></a>
</div>
$('.button').on('hover', function(){
$('#some_other_element').data('oldimg', $('#some_other_element').attr('src')).attr('src','other_image.jpg');
}, function(){
$('#some_other_element').attr('src', $('#some_other_element').data('oldimg'));
});

How to display div with JavaScript depending on which image is clicked

I wish to display certain divs inside a main div dependent on which image is clicked. With out any decent knoweldge of Js or Jquery, I fail to do this without some assistance.
<form>
<input type="hidden" name="prod">
<div id="images">
<img id="one" src="http://lorempixel.com/200/200/">
<img id="two" src="http://lorempixel.com/201/200/ ">
<img id="three" src="http://lorempixel.com/203/200/ ">
<img id="four" src="http://lorempixel.com/204/200/ ">
</div>
</form>
<div id="description">
</div>
<div class="one">Brilliant</div>
<div class="two">Super</div>
<div class="tree">Amazing</div>
<div class="four">Excellent</div>
If the image which has id="one" is clicked, then display <div class="one">Brilliant</div> inside of the description div. Then ofcause if the second image is clicked, then display the the 'super' div inside the description div. I'd like to not have the descriptions visible until clicked, and only one div at a time to be shown.
The images are apart of a form because I need to forward the value of the id on the images to a variable.
Here is the script that does that.
$('#images').delegate('img', 'click', function () {
var $this = $(this);
// Clear formatting
$('#images img').removeClass('border-highlight');
// Highlight with coloured border
$this.addClass('border-highlight');
// Changes the value of the form field prod to the file name shown in the image.
$('[name="prod"]').val($this.attr('id').substring($this.attr('id').lastIndexOf('-') + 1));
//Alert for debugging simplicity
alert($('[name="prod"]').val());
});
Perhaps a function can be implemented into the current script?
Here is a fiddle, and it will all make sense of what I have as a whole currently.
Check out this fidde
You just need to add:
$('#description').html($('.' + $this.attr('id')).html());
At the bottom of your onclick function.
** You have a typo on the 3rd div with text(tree instead of three).
You can make it bit simple by adding the divs for description in div as I see no need to put the divs for description outside the description div and later adding it. You will need to hide all the divs we have in description div and show the one that is related to img being clicked.

only 1 slide is active at a time, I want to somehow find the name of the next div, and write that into the "Test" span tags so that it shows up on hover and if clicked the span tag will then get the name of the next div and update itself, does this make sense? thanks
ADDED FIDDLE
http://jsfiddle.net/TNRMk/
Ive tried this with no luck
$('.arrows').click(function() {
$(".next span").html($('.roundabout-in-focus').next().attr('name'));
$(".prev span").html($('.roundabout-in-focus').prev().attr('name'));
});
Here is a good start for you:
$("div.arrows div").bind("mouseover", function() {
$("div.arrows div.next").children("span").text($("div.roundabout-in-focus").next("div").attr("class"));
$("div.arrows div.prev").children("span").text($("div.roundabout-in-focus").prev("div").attr("class"));
});
A number of points to be made:
This will not work for the prev arrow when the first item is selected.
I wasn't sure which part of the class name you wanted so you will need to do some modification
It needs to be on hover, or in the plugin itself as there are other ways to control the carousel. So setting on click won't work all the time.
The plugin provides callbacks btnNextCallback and btnPrevCallback that are executed after clicking the "next"/"prev" buttons are clicked.
The current focused item has the class .roundabout-in-focus.
I have made this jsfiddle for you to see (all you div have the same content so I've replaced it for the sake of the example).
Here's the (commented) code:
$(document).ready(function() {
function updatePrevNextTitle() {
// as this function is used as a callback for the plugin
// 'this' is the roundabout wrapper div
var $wrapper= $(this),
// get the currently focused div
$frontDiv = $wrapper.find('.roundabout-in-focus'),
// get the next/prev div content relative to the focused div
// also handle the circular roundabout by checking if
// .next() and .prev() return something, otherwise
// get .first() and .last()
nextContent = $frontDiv.next().length
? $frontDiv.next().find('.carousel-caption').html()
: $frontDiv.first().find('.carousel-caption').html(),
prevContent = $frontDiv.prev().length
? $frontDiv.prev().find('.carousel-caption').html()
: $frontDiv.last().find('.carousel-caption').html();
$wrapper.find('.next span').html(nextContent);
$wrapper.find('.prev span').html(prevContent);
};
$('#round').roundabout({
childSelector: 'div.box',
btnNext: ".next",
btnPrev: ".prev",
// set the method updatePrevNextTitle as the callback handler
btnNextCallback: updatePrevNextTitle,
btnPrevCallback: updatePrevNextTitle
}
// set it also as the 'initialized' callback for the
// initial setting of the prev/next span text
,updatePrevNextTitle);
});
One way is to add an active class in your selected div:
//e.g. after the selection event occurs:
$('div').click(function() {
$(this).addClass('active'); //keep track which div is clicked with the active class
//read the class name of the next sibling and store it in test (if i got it right)
$(".Test").html($('.active').next().attr('class'));
});
Maybe not 100% right but can give you a headstart!
According to your jsfiddle the name attribute is missing on your roundabouts,
try this instead:
$('.arrows').click(function() {
$(".next span").html($('.roundabout-in-focus').next().find('.carousel-caption').html());
$(".prev span").html($('.roundabout-in-focus').prev().find('.carousel-caption').html());
});
