I am converting div element to image or screenshot. I've search throughout the internet and found out about html2canvas. I tried using it but no luck. Is there anyone who knows how to make it work? Here is my source code.
<html>
<head>
<title> Screenshot </title>
</head>
<body>
<div id="container">
<h1> Screen shot me </h1>
</div>
<button onclick = "screenshot()"> Capture </button>
</body>
<script src="https://cdnjs.cloudflare.com/ajax/libs/html2canvas/0.4.1/html2canvas.min.js"></script>
<script>
function screenshot(){
html2canvas(document.getElementById('container')).then(function(canvas){
document.body.appendChild(canvas);
})
}
</script>
</html>
My error keeps saying
Uncaught TypeError: html2canvas(...).then is not a function
at screenshot
at HTMLButtonElement.onclick. Did I miss something?
Im using Laravel 5.6 with NPM. Thankyou in advance!
Tested Chrome, Firefox ok, IE 11 needs adding 2 extra js library to support promise.
function takeSnapShot() {
html2canvas(document.querySelector("#capture")).then(function(canvas) {
document.querySelector("#newCanvas").appendChild(canvas);
});
}
<script src="https://cdn.jsdelivr.net/npm/es6-promise#4/dist/es6-promise.min.js"></script>
<script src="https://cdn.jsdelivr.net/npm/es6-promise#4/dist/es6-promise.auto.min.js"></script>
<script src="https://html2canvas.hertzen.com/dist/html2canvas.min.js"></script>
<div id="capture" style="padding: 10px; background: #f5da55">
<h4 style="color: #000; "> Screen shot me </h4>
</div>
<input type="button" value="Capture" onclick="takeSnapShot()"/>
<div id="newCanvas"></div>
</html>

So basically I have this code where I click on the image, it gets html file and should display it on the same page. It does display it but on another page, my guess is that it's not actually loading js file for some reason. Anyone can help?
View:
#extends('layouts.master')
#section('title', 'Best programmer ever')
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js"></script>
<script src="{{asset('/js/template.js')}}" rel="javascript" type="text/javascript"></script>
#section('content')
#endsection
#section('template')
<!-- #foreach ($templates as $template)
{{$template->image}}
{{$template->file}}
#endforeach
-->
<div class= "template_class">
<a class="content-link" href="templates/template1.html">
<img id = "image" src="{{ asset($template->image )}}"/>
</a>
</div>
#show
JavaScript:
$(function(){
$('.content-link').click(function(e){
e.preventDefault();
$('.content').load(this.href)
.fail(function()( alert('Oops...something went wrong')));
});
});
alert("hello");
It doesn't even show alert so that's why I think it is not loading it.
The <script> tags are out of the #section sections.
Try changing it like this:
#section('content')
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js"></script>
<script src="{{asset('/js/template.js')}}" rel="javascript" type="text/javascript"></script>
#endsection
If it doesn't work, check if the JS files are really included in your browser. (Open the Chrome Dev Tools and check the DOM)
I have a maybe-noob question for those who know how works jQuery mobile in its core :)
I see on some websites an ajax-like navigation, but with an URL completely changed after load (I mean, no hash at the end).
For example : http://m.wengo.fr/accueil
=> click on any link, you'll see a loader, and after a little animation the new page is loaded ; but the URL has no hash, it's a real new URL.
Is the page really fully reloaded after a first ajax-load behind ?
I don't see how this magic is did on their framework...
Thanks ;)

This is a rather easy implementation.
Page changes should be handled programatically with changePage function (jQuery Mobile 1.4 and below) or pageContainer change (jQuery Mobile 1.4 and above).
Solution:
$.mobile.changePage("second.html", { transition: "slideup", changeHash: false });
What you need is changeHash set to false.
Example:
index.html
<!DOCTYPE html>
<html>
<head>
<title>jQM Complex Demo</title>
<meta http-equiv='Content-Type' content='text/html; charset=utf-8'/>
<meta name="viewport" content="width=device-width; initial-scale=1.0; maximum-scale=1.0; minimum-scale=1.0; user-scalable=no; target-densityDpi=device-dpi"/>
<link rel="stylesheet" href="http://code.jquery.com/mobile/1.4.2/jquery.mobile-1.4.2.min.css" />
<script src="http://code.jquery.com/jquery-1.10.1.min.js"></script>
<script src="http://code.jquery.com/mobile/1.4.2/jquery.mobile-1.4.2.min.js"></script>
<script>
$(document).on('pagebeforeshow', '#index', function(){
$(document).on('click', '#open-page', function(){
alert('sdfsd');
$.mobile.changePage("second.html", { transition: "slideup", changeHash: false });
});
});
</script>
</head>
<body>
<div data-role="page" id="index" data-theme="a" >
<div data-role="header">
<h3>
First Page
</h3>
<a class="ui-btn-right" id="open-page">Next</a>
</div>
<div data-role="content">
</div>
<div data-role="footer" data-position="fixed">
</div>
</div>
</body>
</html>
second.html
<div data-role="page" id="second" data-theme="a" >
<div data-role="header">
<h3>
Second Page
</h3>
Back
</div>
<div data-role="content">
</div>
<div data-role="footer" data-position="fixed">
</div>
</div>
Update:
Information you need has nothing to do with jQuery Mobile.
I showed you one solution which jQuery Mobile can actually do. But this solution will permanently show original HTML file name. This is because initial HTML page is loaded into the DOM and every other page is loaded into it. jQuery Mobile thus have full control over link name.
But this is not what mentioned page is using. It is using some kind of rewrite engine. By default, rewrite engine maps a URL to a filesystem path. However, it can also be used to redirect one URL to another URL (which is done here), or to invoke an internal proxy fetch. They are probably using Apache web server with mod_rewrite module turned on.
I have a website like:
<!DOCTYPE html>
<html>
<body>
<script src="jquery-2.0.3.min.js"></script>
<div id="block">
<span id="c1" class="chunk">first </span>
<span id="c2" class="chunk">second </span>
<span id="c3" class="chunk">third </span>
</div>
<script>
var my = {
mousedown: function(event) {
$('.chunk').each(function() {
this.setAttribute('contenteditable', 'false');
});
},
mouseup: function(event) {
$('.chunk').each(function() {
this.setAttribute('contenteditable', 'true');
});
}
};
$('.chunk')
.on('mousedown', my.mousedown)
.on('mouseup', my.mouseup)
;
my.mouseup(null);
</script>
</body>
</html>
The desired outcome is like in chrome:
when I click the chunk, I can write text and I see a caret (cursor)
and when I select the contenteditable gets disabled for the time of selection
BUT IN FIREFOX:
I can not type anymore inside the contenteditable
because the onmousedown disables the contenteditable in time of onclick (I think)
CAN U HELP WITH FIX? I'm looking for cross-browser solution to this.
PLEASE
The answer appeared to be simpler thant I thought. The main containing parent has to have contenteditable=true, after this, everything worked in every browser like it should. And now the mousemove and mousedown simulating selectstart also work like they should (another feature of this project), so remember when having similar problem: just create one contenteditable main container and you will not have problems with selections
<!DOCTYPE html>
<html>
<body>
<script src="jquery-2.0.3.min.js"></script>
<div id="block" contenteditable="true">
<span id="c1" class="chunk">first </span>
<span id="c2" class="chunk">second </span>
<span id="c3" class="chunk">third </span>
</div>
</body>
</html>
Does anyone know of a jquery plugin that has a background slide show and a gallery that changes background images every time someone opens the site or every hour or so?
There are lot of jQuery slideshow plugins. I would recommend you to look at the following:
Slide JS - http://www.slidesjs.com/
<head>
<title>Title</title>
<style type="text/css" media="screen">
.slides_container {
width:570px;
height:270px;
}
.slides_container div {
width:570px;
height:270px;
display:block;
}
</style>
<script src="http://code.jquery.com/jquery-latest.min.js"></script>
<script src="slides.js"></script>
<script>
$(function(){
$("#slides").slides();
});
</script>
</head>
<body>
<div id="slides">
<div class="slides_container">
<div>
<img src="http://placehold.it/570x270">
</div>
<div>
<img src="http://placehold.it/570x270">
</div>
<div>
<img src="http://placehold.it/570x270">
</div>
<div>
<img src="http://placehold.it/570x270">
</div>
</div>
</div>
</body>

I need fadeout a div in my page using prototype. How can I fadeout following jquery code in prototype?
$('.exercise-main .content .loading-failure').fadeOut(function(){
//my code
}
I think you will need to use script.aculo.us (which is an excellent add-on to the fantastic prototype.js) so as to achieve the Fade effect.
Basic Syntax
new Effect.Fade('id_of_element', [options]);
OR
new Effect.Fade(element, [options]);
Complete Code.
<html>
<head>
<title>script.aculo.us examples</title>
<script type="text/javascript"
src="/javascript/prototype.js"></script>
<script type="text/javascript"
src="/javascript/scriptaculous.js?load=effects"></script>
<script type="text/javascript">
function FadeEffect(element){
new Effect.Fade(element,
{ duration:1});
}
function ShowEffect(element){
new Effect.Appear(element,
{duration:1, from:1.0, to:1.0});
}
</script>
</head>
<body>
<div onclick="FadeEffect('hideshow')">
Click me to fade out the image
</div>
<br />
<div onclick="ShowEffect('hideshow')">
Click me to display the image once again
</div>
<br />
<div id="hideshow">
<img src="/images/scriptaculous.gif" alt="script.aculo.us" />
</div>
</body>
</html>

I myself have used prototype.js and this add-on very heavily so just in case you face any issue, feel free to comment.. :-)
