I'd like to implement this situation: user hovers link and on his screen appears div with additional information.
There is no problem, to generate div with absolute position, populate data and display it with jQuery, but the problem is with maintainability. I want to separate logic and view. What if I'd like to change page layout in the future? How programmer will know, that some part of page exist in JavaScript file?
Is it some elegant way to separate view (in my case HTML structure) and logic (data obtained from server in JSON using JS script) and combine them? Is it any ... templating engine or something like that in JavaScript?
You can generate your HTML entries like this
<a>
My Cool Link
<div class="tooltip">
This link is awesome!
</div>
</a>
And use CSS to style the tooltip:
(The important part is a:hover .tooltip and everything except background on .tooltip
a {
display: inline-block;
}
a:hover .tooltip {
visibility: visible;
}
.tooltip {
position: relative;
top: 20px;
left: -50%;
display: inline;
visibility: hidden;
background: #eee;
}
Example: http://jsfiddle.net/4K7sB/
Then you just need to populate the elements with the correct text using JS.
Bootstrap does all this and more: http://getbootstrap.com/javascript/#tooltips
To put it in:
$('#example').tooltip(options)
And the markup being:
<div class="tooltip">
<div class="tooltip-inner">
Tooltip text here!
</div>
<div class="tooltip-arrow"></div>
</div>
Go to the link for a more detailed explanation on how to implement it
You can alter the Title="information" dynamicaly by some program or script and use the following code to display it as a tool tip,found it on net
http://www.webdesignerdepot.com/2012/11/how-to-create-a-simple-css3-tooltip/
Just add title attribute in div tag like below code....
<div title="First Div">StackOverFlow StackOverFlow StackOverFlow
StackOverFlow StackOverFlow StackOverFlow StackOverFlow StackOverFlow
StackOverFlow </div>
</div>
<br /><br />
<div title="Second Div">StackOverFlow StackOverFlow StackOverFlow
StackOverFlow StackOverFlow StackOverFlow StackOverFlow StackOverFlow
StackOverFlow </div>
</div>
just copy paste and check.

thank you for taking the time to review my question! :-) I am attempting to write better, cleaner, more maintainable HTML using custom HTML elements as opposed to the traditional 'div' methods. I have a very simple example that works using a div and a class on it to map my link to the div that I want to show/hide and this does work. I include this as a working example of the kind of functionality I am trying to produce:
<html>
<head>
<style>
<!-- Not sure if display or visibility is the way to go so will look -->
<!-- that later, for now just setting both as that works -->
<!-- For some reason doing this does not seem to work -->
.hidden {
display: none;
visibility: hidden;
}
.unhidden {
display: block;
visibility: visible;
}
<!-- but, doing this does, anyone any idea why? -->
.hidden { display: none; }
.hidden { visibility: hidden; }
.unhidden { display: block; }
.unhidden { visibility: visible; }
</style>
<script type="text/javascript">
function toggle_view_div(divID) {
var item = document.getElementById(divID);
if (item) {
item.className=(item.className=='hidden')?'unhidden':'hidden';
}
}
</script>
</head>
<body>
<p>
This test shows or hides a div referenced by its class
</p>
Do the test
<div id="testToggleDivID" class="hidden">
<h3>Testing Toggling HTML</h3>
</div>
</body>
</html>
However, I am trying to provide this kind of functionality with multiple links to multiple sets/subsets of text, I have tried the following but am obviously doing something silly as I can't get it to work:
<html>
<head>
<script type="text/javascript">
function toggle_view_node(nodeID) {
nodeID.getAttribute('visibility')=('hidden')?item.setAttribute('visibility','visible'):item.setAttribute('visibility','hidden');
nodeID.getAttribute('display')=('none')?item.setAttribute('display','block'):item.setAttribute('display','none');
}
</script>
</head>
<body>
<p>
This test shows or hides Topic 1 custom element, (or at least attempts to
</p>
Topic 1
<p>
This test shows or hides Topic 2 custom element, (or at least attempts to
</p>
Topic 2
<p>
<p>
This test shows or hides the Intro custom element, (or at least attempts to
</p>
Introduction
<p>
This test shows or hides the Detail custom element, (or at least attempts to
</p>
Detail
<p>
<Intro>Some introduction text giving a more detailed overview that may want to be hidden by default, but able to be toggled into view with an always visible link such as at the top or on the side of the page</Intro>
<Detail>I may want to add detail with this ability both like this at the root of the document, but potentially inline with other text in custom elements as shown below</Detail>
</p>
<Topic1>
<h1>Topic 1</h1>
<p>
Some topics to be just simple nodes of text.
</p>
</Topic1>
<Topic2>
<h1>Topic 2</h1>
<p>
Other topics to be more detailed topics, <Topic1>potentially including aspects of that can share the toggle feature for the root level topic 1, as per all topic 1 nodes</Topic1> though generally referencing only topic 2 content. <Detail>However it would be nice to be able to toggle not directly relevant, but nice to have detail as well</Detail>
</p>
</Topic2>
<Topic3>
<h1>Topic 3</h1>
<p>
<Intro>Some topics might want an intro<Detail>, that may want further detail contained in them</Detail> that would also provide sufficient intro in itself.</Intro>
So, is this possible? I don't want specific control of sub custom elements, and can do it with div's and assigned classes if I really have to, but surly it is possible with a bit of special JS or CSS to do what I am looking for?</p>
</Topic3>
</body>
</html>
Please, can someone help me figure out what I am doing wrong. I really want to produce the aforementioned functionality with a simple bit of CSS or JS that is as dynamic as possible. Ideally I wont need to specify specific (especially repeated code for each topic or HTML tag that I want the ability to show/hide via a button/link. Obviously, I will probably have to set a few default assignments, maybe turning detail off by default, but if I can avoid required extra repetitive code for each "context" I wish to flip that would be amazing!!!
Any pointers in any direction that can help me achieve what I am attempting without having to use jQuery or a verbose library over and above JS and CSS would really make my day!
Many thanks in advance and apologies if I am doing something really stupid, I haven't done that much work with custom elements and so probably am.
Kind regards,
James

you don't need a .unhidden class, only a .hidden class. It looks like:
.hidden{
display:none;
}
simply use classList like classList.toggle("hidden") or .add or .remove.
How can I unable website preview feature on all of the links in my web page? That is when the user moves the mouse over any link in the page, I want to show a simple pop up window which loads the page in link. I tried doing it on my own with help of Google and stackoverflow. But result got something like this -
(ACTUAL PAGE LINK RENDERING)
How should I fix this? I wanted to have it similar to Google instant preview.
Here is my code - (website links are fetched from web service)
html file
<div class="text-result" *ngIf="Display('all')">
<div *ngFor="let item of items$|async" class="result">
<div class="frame">
<script>
$(".head-link").mouseover(function() {
$(this).children(".tooltip").show();
}).mouseout(function () {
$(this).children(".tooltip").hide();
});
</script>
<div class="title">
<a href="{{item.link}}" class="head-link">{{item.title}}
<iframe id="tooltip" src="{{item.link}}"></iframe>
</a>
</div>
</div>
<div class="link">
<p>{{item.link}}</p>
</div>
<div>
{{item.pubDate|date:'fullDate'}}
</div>
</div>
</div>
css file
.head-link {
color: #069;
cursor: pointer;
}
.tooltip {
display: none;
position: absolute;
border: 1px solid #000;
width: 400px;
height: 400px;
}
I setup a minimal JS fiddle for you, and I believe I resolve the issue.
A summary of my changes is:
Your iframe has an id=tooltip, when you are referencing it as .tooltip, so I changed it to class=tooltip.
Your jQuery script has to appear after the elements on the page that are used by it, so I moved the script tags to the bottom of the class=text-results div.
Two notes:
First, this isn't an Angular 2 problem, you are using Angular 2 in your project, but the problem is with your jQuery code.
Second, you really should avoid using jQuery to solve your problems within an Angular 2 project. Angular 2 has the capability to solve this problem without needing to include jQuery. Mixing jQuery and Angular 2 will result in messy and hard to understand code, you are much better off trying to solve this problem using only Angular 2.
quick question from a complete JS noobie.
On a site, I have an image of a product consisting of basically two parts, then I have a row of small .png thumbnails .colorthumbnail of those separate parts with transparent backgrounds. In the CSS I set it so that when hovering the thumbnails, it enables the .colorzoom class that overlays a big version of the same color option over the original product picture using position: absolute.
HTML:
<div class="coloroptions">
<div class="j210desertsand">
<div class="colorthumbnail">
<a href="javascript:void(0)" id="colorpicker">
<img src="img/products/colors/j210desertsand.png"></a>
<span class="colorzoom"><img src="img/products/colors/j210desertsand.png">
</span></div></div>
<div class="j210platinum">
<div class="colorthumbnail">
<a href="javascript:void(0)" id="colorpicker">
<img src="img/products/colors/j210platinum.png"></a>
<span class="colorzoom"><img src="img/products/colors/j210platinum.png">
</span></div></div>
</div>
The <div class="j210desertsand">classes are simply there so I can easily hide a single color option using CSS and the next colour will line up. The anchor points are there cause after some research I found I should actually make the thumbnails clickable and with a href="javascript:void(0)" they don't actually link anywhere or reload the page.
CSS: (Excuse the mess, I'm inexperienced)
.coloroptions {
width: 60%;
margin-left: 40%;
}
.colorthumbnail {
margin-left: -45%;
}
.colorthumbnail img {
float: left;
max-width: 16%;
padding-right: 5px;
position: relative;
}
.colorthumbnail .colorzoom {
position: absolute;
width: 253%;
margin-top: 6.9%;
display: none;
margin-left: -3.6%;
}
.colorthumbnail:hover .colorzoom {
display: block;
}
Now this appears to work fine, but because there are two different parts I want to give the user the ability to combine color options and obviously you can't hover over two images at once. After some more research I found that I need Javascript to force the :hover state on click. But I'm gonna be honest, I have no idea what I'm doing. This is what I have:
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
</head>
<!-- -----------------------JSQuery------------------------- -->
<script>
$("#colorpicker").click(function() {
$('.colorthumbnail:hover').toggleClass('colorthumbnail:hover .colorzoom');
});
</script>
<!------------------------ JSQuery End -------------------------->
However this does not appear to be working. Did I get the linked script in the <head> right? It did work alright with the 'Hello World' pop-up test. Did I get the classes in the script right? I'm a little stuck and help would be appreciated! Much love for the community.
Try adding your code like this:
$( document ).ready(function() {
$("#colorpicker").click(function() {
$('.colorthumbnail:hover')
.toggleClass('colorthumbnail:hover.colorzoom');
});
});
When trying to use jquery you need to make sure the page is loaded so it can perform dom manipulation.

Here is a jsFiddle demo: https://jsfiddle.net/Lv571n1w/
If you inspect element you can see it toggle the classes when clicked.
This question already has answers here:
How do I select an element based on the state of another element in the page with CSS?
(3 answers)
Closed 7 years ago.
I can't quite get my head around this. I have the following construct:
<div class="container">
for n = 0 to ...
Link n
endfor
for each link in ".container"
<div class="poptip"></div>
endfor
</div>
And an example could be:
<div class="container">
Link 1
Link 2
Link 3
<div class="poptip">Some content related to link 1 retreived with ajax</div>
<div class="poptip">...</div>
<div class="poptip">...</div>
</div>
Now the hurdle, I am trying to show the .poptip on hover on the anchor tag, and this obviously works fine if there is one link (which is usually the case). In any case where there's >1 link, then the last one will work. Current css (sass style) which doesn't quite work in >1 cases:
.producttooltip {
position: relative;
}
.producttooltip a:hover + div {
display: block;
}
I cannot change the structure of the html, it will always be container > all links followed by all poptips. I can however mark the poptips and anchor tags up with unique identifiers e.g. Link 1<div class="poptip" rel="identifier"></div>, but I can't quite figure out if I in css can create a general selector which goes (pseudo):
a:hover + div[rel=a.rel] {
display: block
}
So my question is, can I get this construct marked up in pure CSS, or do I have to use some JS trickery (which I can, but I would really prefer CSS). Hope one of you guys are more clever than me.
Edit: just gonna clarify - I cannot change the structure of the html. The neatest solution would obviously be to wrap each element with it's equivalent poptip, but my entire conundrum is the fact that I cannot do this.
In your case, you can do this way:
$('a').on('hover', function() {
$('.poptip').eq($(this).index()).show();
}, function() {
$('.poptip:visible').hide();
});
It is tough to do this with CSS alone. But even then, I have provided a CSS solution below. Do have a look if you wanna consider a CSS only solution.
You can do this via CSS itself. Although there are lot of plugins, lets do something like this. First, you need a hovering element, say in this case, a link.
Hover Me!
Next should be the tool tip. We can have a <span> for now and put it inside the link.
Hover Me!<span class="tooltip">Hello, World!</span>
Now comes the real CSS part.
a span {display: none; position: absolute; color: #fff; background: #000; padding: 5px;}
a {position: relative;}
a:hover span {display: block; text-align: center;}
Snippet
a span {display: none; position: absolute; color: #fff; background: #000; padding: 5px;}
a {position: relative;}
a:hover span {display: block; text-align: center;}
Hover Me!<span class="tooltip">Hello, World!</span>
This is just one of a pure CSS solution. You can see the working fiddle here.
However, there are a lot of plugins, which keep this concept as base and work for hover-cards and tool tips. Some good examples include:
jQuery UI Tooltip
Tipsy
HoverCard
40+ Tooltips Scripts With AJAX, JavaScript & CSS
jQuery solution
You can use mouseenter/mouseleave event in order to show up the desired elements
$('a').on('mouseenter', function() {
var i = $(this).index();
$('.poptip').eq(i).show();
}).on('mouseleave', function() {
$('.poptip').hide();
});
.poptip {
width:100%;
float:left;
display:none;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<div class="container">
Link 1
Link 2
Link 3
<div class="poptip">Some content related to link 1 retreived with ajax</div>
<div class="poptip">Some content related to link 2 retreived with ajax</div>
<div class="poptip">Some content related to link 3 retreived with ajax</div>
</div>
Using jquery this can be achieved easily, just need to get the index of the current anchor element & display the respective div present at the index location.
HTML CODE:
<div class="container">
Link 1
Link 2
Link 3
<div class="poptip">Some content related to link 1 retreived with ajax</div>
<div class="poptip">...</div>
<div class="poptip">...</div>
</div>
JS CODE:
$(function(){
$('a').on('hover',function(){
var ind = $('a').index(this);
$('.poptip').eq(ind).css('display','block');
});
});

Is there a jQuery library or any leads on implementing that photo tagging like in Facebook and Orkut Photo albums?
Thanks
Hmmm, I found that the new version of Img Notes seems to do exactly what you want.
Checkout the Demo. It allows you to easily add tag notes and show them using JQuery. He also depends on the imgAreaSelect jquery plugin for adding notes.
you could try Jcrop or imgAreaSelect.
Not 100% the same behaviour as in Facebook, but with some tweaks, this should e possible.
I didn't find any suitable plugins for this purpose. So I ended up writing myself a small plug-in to mark areas over an image based on the coordinates loaded through an XML file.
The basic code is required is:
<div id="imageholder">
<!-- The main image -->
<img src="<link to image file>" alt="Image">
<!-- The grid tags -->
<div class="gridtag" style="bottom: 100px; left: 106px; height: 41px; width: 41px;"/>
<div class="gridtag" style="bottom: 300px; left: 56px; height: 100px; width: 56px;"/>
<div class="gridtag" ...
</div>
And the basic CSS styling required:
#imageholder{
height:500px;
width:497px;
position:relative;
}
div.gridtag {
border:1px solid #F0F0F0;
display:block;
position:absolute;
z-index:3;
}
In the above the divs with class "gridtags" are added using jQuery through XML or JSON and by binding events on this divs, we can make phototagging similar in Orkut.
PS: This only one side of the phototagging, ie. if we already have the coordinates we can mark on an image and add click events, which is the part actually i wanted. :) You guys has to write code for doing the marking part of the phototagging.
A good and complex example of tag like functionality in facebook is
Talking Pictures, Which is a facebook application.
