I want to build a simple online editor like plunker. Does anyone know how to accomplish the live preview, once several files (.html, .css, .js, .json) have been uploaded?
Taking JSBin as example, there are only 1 html text, 1 css text and 1 js text, so it is simple: we just need to construct one complete html file from these texts and use Document.write().
However, how do editors such as plunker, brackets, vscode do live preview? Do they also construct one complete file by themselves or they use some third-party tools?
Live previews are pretty easy. Just replace the HTML of an area on the page with the HTML the user provided. In practice, you probably want to do this in a sandboxed iframe for security purposes.
The snippet below shows how this can be done, all in JavaScript. Try running the snippet and typing in the box.
function doLivePreview() {
$("#output").html($("#source").val());
}
$(function() {
doLivePreview();
$("#source").on("input", doLivePreview);
});
#source {
float: left;
}
#output {
float: left;
border: 1px solid #AAA;
margin-left: 5px;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<textarea id="source" cols="50" rows="8">
Type to see a live preview
<br/>
<a href="https://www.google.com">Google<a>
</textarea>
<div id="output">
</div>

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.
I'm not a programmer, I've created a web site using a major hosting service's application. I want to insert code into a box provided by the hosting service that allows you to paste any HTML code.
I want to create a link on the site that opens a popup window to display text that I hard-code into the code. I don't want to jump to another HTML page.
I found the following code below that allows me to jump to another HTML page (it was set to CNN.com as an example). Is there a way to replace the action of jumping to another HTML page, with opening the popup and displaying the following example text "hello world". (please note in the code below, I deleted the opening and closing "a" tags at the beginning and end of the code since their inclusion causes problems when I type this question out on this web site).
Pop-up Window
Thanks
Easy to make popup window without Jquery. Just copy this code and paste. and clicl the open text. Popup shown.
<p>To display the box, click on the link <a href="#" onClick="document.getElementById('shadowing').style.display='block';
document.getElementById('box').style.display='block';">open</a>
</p>
<div id="shadowing"></div>
<div id="box">
<span id="boxclose" onClick="document.getElementById('box').style.display='none';
document.getElementById('shadowing').style.display='none'">close </span>
<div id="boxcontent">
And this is the static content of the box. <br><br>
Dynamic content in the next demo...
</div>
</div>
<style type="text/css">
#shadowing{display: none;position: fixed;top: 0%;left: 0%;width: 100%;height: 100%; background-color: #CCA; z-index:10; opacity:0.5; filter: alpha(opacity=50);}
#box {display: none;position: fixed;top: 20%;left: 20%;width: 60%;height: 60%;max-height:400px;padding: 0; margin:0;border: 1px solid black;background-color: white;z-index:11; overflow: hidden;}
#boxclose{float:right;position:absolute; top: 0; right: 0px; background-image:url(images/close.gif);background-repeat:no-repeat; background-color:#CCC; border:1px solid black; width:20px;height:20px;margin-right:0px;}
#boxcontent{position:absolute;top:23px;left:0;right:0;bottom:0;margin:0 0 0 0;padding: 8px;overflow: auto;width:100%;height:100%; overflow:hidden;}
</style>
You can place the function in the <head> section OR you can pull the function from a .js file. This will open a window and load the url you want. It won't redirect the original page as you use the # instead of the actual url.
<script>
function popup(){
window.open('http://www.cnn.com','1426494439650','width=440,height=300,toolbar=0,menubar=0,location=1,status=1,scrollbars=1,resizable=1,left=0,top=0')
}
</script>
link
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.
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.
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.
