How to enable and fix preview page on link hover? - javascript

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.

load some content from txt and add to html markup

Have some markup
<div class="container">
<aside class="left">
<div class="item"><p>lorem ipsum</p></div>
</aside>
<aside class="right">
<div class="item"></div>
</aside>
</div>
<button>load more</button>
css
aside {
display: inline-block;
width: 40%;
border: 1px solid red;
margin: 2%;
vertical-align: top;
}
.item {
border-bottom: 1px solid black;
}
I need to load some html content from .txt file when clicking button and add that markup inside both aside. In .txt file markup like this
<div class="item"><p>lorem ipsum1</p></div>
<div class="item"><p>lorem ipsum2</p></div>
<div class="item"><p>lorem ipsum3</p></div>
<div class="item"><p>lorem ipsum4</p></div>
I want "drag" and paste first div with class .item to aside.left, second div with class .item in aside.right, third div with class .item in aside.left and so on...
Is there any solution? I don't know how paste .item divs in both columns..
Thanks for any help
Here is JsFiddle DEMO
upd: I'm only use css+html+some jquery, I dont know any things on php or server technology.. but programmer who work with my markup says that I need to demonstrate how content will be added on click.. So I dont know is this my work, or this is programmer need to do.. I need your answer about this..
If that helps, here is LINK you can see site. In bottom you can see arrow, onclick on that there need add content in columns..
P.S. Programmer works with Yii framework.
Since you already seem to know about AJAX (you added the tag), I think you have your answer there.
You can just use AJAX to get any chunk of data from the server and add it to the page.
Since you are working together with a server-side programmer, I think each of you could build their own part independantly.
All you need is an API that you can use, to which you can specify the offset of items to load, so you could call /getitems?offset=12&count=4 to get the next 4 items from item 12.
You can then just make a simple page that returns dummy data. getitems.php can just return the same constant items every time, and all you need to do is add those items at the bottom of your list.
At the same time, the PHP programmer can actually implement that page so it returns the same data. He can make it in such a way that it also works for non-AJAX request, so he can easily test it without needing your front-end code.

django-cms div tags with cmsplugin class interfering with slider

I am using Django CMS 3.0.3. I've written a cms plugin with 2 CMSPluginBase derived classes, one adds a slider to a placeholder and another one is for adding slides as children to the slider.
In live mode everything works fine, but when I am editing content, I can't use the slider. The reason is that django-cms is decorating the html code with additional elements like this:
<div class="slider">
<div class="cms_plugin cms_plugin-2" style="width: 0px; overflow: hidden; position: absolute; left: 0px; display: block;">
<!-- Slider Item -->
<div class="slider-item"> [MY SLIDER CONTENT] </div>
<!-- /Slider Item -->
</div>
</div>
I got the HTML/CSS/JS from somebody else and I would preferable not use another slider. What options do I have to work around this problem?
Is there a way in django-cms to switch off the wrapping of plugins in "content mode" only, but to have the placeholder <div> included in "structure mode"? That would not be super convenient, but a workaround that I can live with.
Is there something else, I could do? I don't want to touch the slider itself. It might get an update and then I'd have to adjust it to adjust the slider to my needs again.
django-cms is need to wrap your plugin with <div class="cms_plugin cms_plugin-2"> for relation with "structure mode". There are no other variants.

JavaScript - tooltip div on hover

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.

jQuery with Wordpress Loop. Show / Hide content?

At the moment I have a website that grabs the 12 most recent posts from a category, and displays them as a link to their permalink, with the post thumbnail image as the link image.
You can see a working example here: http://mathewhood.com/sitefiles/
What I want to do, is somehow add functionality into my loop that will allow me to make it so that when you click on one of these list elements, it will display the_content(); for each element.
I found this - http://gsgd.co.uk/sandbox/jquery/easing/ Which I think may provide the functionality that I want (ideally jswing in and out), but I am struggling at implementing it! If anyone knows how I could make this happen please answer this and receive your well deserved up-votes!
http://jsfiddle.net/XzJgU/ - Here is my current loop so far, any help will be greatly appreciated!!!!!!!!!
Here is my solution to your problem. I'm giving an example on how to implement jquery Easing.
EDIT
revised my post, please
View revised sample here
Hope it helps.
$('.thumbs').click(function(e){
e.preventDefault();
var contents = $(this).closest('.recentPost').find('.caption').html();
var $container = $('#theContainer').html(contents);
$container.show().animate({height:200}, {duration: 1000, easing: 'jswing'}).animate({height:100}, {duration: 1000, easing: 'easeInOutCirc'});
$container.click(function(){
$container.animate({height:200}, {duration: 1000, easing: 'easeInExpo'})
$container.fadeOut('slow');
$container.html('');
});
});
Something like that should work - http://jsfiddle.net/XzJgU/5/. It renders the content for each post in the loop, hidden by default using CSS. When a post is clicked, it moves its content to #displayed-post, making it visible. When another post is clicked, its moves back to its original container and the new post content is moved there.
I'm not entirely clear on how you want this to work - are you looking for a PHP solution or a JavaScript one or perhaps a mix of the two. I've got two suggestions on how you might make it work. Also, note that the jQuery library you're referring only adds easing options to jQuery - i.e. it only deals with animation and not with the business logic and behaviour of your code.
Using ajax
This should work in this case since you're not making cross-domain requests. Essentially, you'd intercept the click to the link, figure out where it's pointing and then make a GET request to that page. You'd then filter out the appropriate HTML from the response and put it into your page. Something like this:
$('.recentPost a').click(function(){
$.get($(this).attr('href'), function(data){
//make a get request to the page the link linked to
//and extract the blog content div
$("placeholder").html($(data).filter(".blogRight"));
});
return false; //cancel the browser's default action on click to keep user on page
});
where you'd have a <div id="placeholder" /> in your HTML page where you'd like the content to appear.
Using PHP + JavaScript
Instead of fetching the content on demand, you'd generate it when the page loads but keep it hidden. You'd again intercept clicks but this time you'd find and display the appropriate, existing div on the page.
So your generated page would look something like this:
<div id="contentWrap">
<div class="hidden-featured-content" id="content-f12">
<div>Your content here</div>
</div>
<div class="hidden-featured-content" id="content-f11">
<div>Your content here</div>
</div>
<div id="newBanner"></div>
<div class="recentPost">
<img width="204" height="144" src="http://mathewhood.com/sitefiles/wp-content/uploads/2011/08/featured12.png" class="attachment-post-thumbnail wp-post-image" alt="featured12" title="featured12" />
<a href="http://mathewhood.com/sitefiles/?p=35"><div class="caption">
<div class="captionTitle">Hello World 12!</div>
<p></p>
</div></a>
</div>
<div class="recentPost">
<img width="204" height="144" src="http://mathewhood.com/sitefiles/wp-content/uploads/2011/08/featured11.png" class="attachment-post-thumbnail wp-post-image" alt="featured11" title="featured11" />
<a href="http://mathewhood.com/sitefiles/?p=32"><div class="caption">
<div class="captionTitle">Hello World 11!</div>
<p></p>
</div></a>
</div>
...
You could then use something like to toggle the appropriate content
$('.recentPost a').click(function(){
if($(this).attr('id')){
var x = /link-(.*)/.exec($(this).attr('id')); //figure out which content- div to display
$('.displayed').hide().removeClass('displayed'); //hide already displayed content
$('#content-' + x[1]).show().addClass('displayed'); //show content and mark it as displayed
return false;
}
});
There are a number of ways to achieve this. The most efficient would probably be a full ajax solution but that would require a Wordpress plugin and some advanced scripting.
The most straightforward solution would be to add a box for dynamic content, output the content for each post in a hidden DIV under it's permalink/image, then use javascript to move content from the hidden DIVs to the dynamic content box when a permalink is clicked. I've worked up some code at http://jsfiddle.net/HF9Pr/.
Try this:
<head>
<script type="text/javascript" src="jquery.js"></script>
<script type="text/javascript">
$(document).ready(function(){
$(".flip").click(function(){
$(".panel").slideToggle("slow");
});
});
</script>
<style type="text/css">
div.panel,p.flip
{
width: 203px;
margin: 0px;
padding-top: 9px;
padding-bottom: 9px;
padding-left: 12px;
padding-right: 12px;
background: #c1e0fb;
border-left: 1px dashed #aaa;
border-right: 1px dashed #aaa;
}
div.panel
{
height: 288px;
display: none;
border-top: 1px dashed #aaa;
}
p.flip
{
border-top: 1px dashed #aaa;
border-bottom: 1px dashed #aaa;
}
</style>
</head>
<body>
<div class="panel">

Phototagging like in Facebook and Orkut album photos?

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.
