The JavaScript code window.print() can print the current HTML page.
If I have a div in an HTML page (for example, a page rendered from an ASP.NET MVC view), then I want to print the div only.
Is there any jQuery unobtrusive JavaScript or normal JavaScript code to implement this request?
Making it more clear, suppose the rendered HTML page is like:
<html xmlns="http://www.w3.org/1999/xhtml">
<head id="Head" runat="server">
<title>
<asp:ContentPlaceHolder runat="server" ID="TitleContent" />
</title>
</head>
<body>
<div id="div1" class="div1">....</div>
<div id="div2" class="div2">....</div>
<div id="div3" class="div3">....</div>
<div id="div4" class="div4">....</div>
<div id="div4" class="div4">....</div>
<p>
<input id="btnSubmit" type="submit" value="Print" onclick="divPrint();" />
</p>
</body>
</html>
Then I want to click on the Print button, only printing div3.
I would go about it somewhat like this:
<html>
<head>
<title>Print Test Page</title>
<script>
printDivCSS = new String ('<link href="myprintstyle.css" rel="stylesheet" type="text/css">')
function printDiv(divId) {
window.frames["print_frame"].document.body.innerHTML=printDivCSS + document.getElementById(divId).innerHTML;
window.frames["print_frame"].window.focus();
window.frames["print_frame"].window.print();
}
</script>
</head>
<body>
<h1><b><center>This is a test page for printing</center></b><hr color=#00cc00 width=95%></h1>
<b>Div 1:</b> Print<br>
<div id="div1">This is the div1's print output</div>
<br><br>
<b>Div 2:</b> Print<br>
<div id="div2">This is the div2's print output</div>
<br><br>
<b>Div 3:</b> Print<br>
<div id="div3">This is the div3's print output</div>
<iframe name="print_frame" width="0" height="0" frameborder="0" src="about:blank"></iframe>
</body>
</html>
Along the same lines as some of the suggestions you would need to do at least the following:
Load some CSS dynamically through JavaScript
Craft some print-specific CSS rules
Apply your fancy CSS rules through JavaScript
An example CSS could be as simple as this:
#media print {
body * {
display:none;
}
body .printable {
display:block;
}
}
Your JavaScript would then only need to apply the "printable" class to your target div and it will be the only thing visible (as long as there are no other conflicting CSS rules -- a separate exercise) when printing happens.
<script type="text/javascript">
function divPrint() {
// Some logic determines which div should be printed...
// This example uses div3.
$("#div3").addClass("printable");
window.print();
}
</script>
You may want to optionally remove the class from the target after printing has occurred, and / or remove the dynamically-added CSS after printing has occurred.
Below is a full working example, the only difference is that the print CSS is not loaded dynamically. If you want it to really be unobtrusive then you will need to load the CSS dynamically like in this answer.

For printThis.js souce code, copy and pase below URL in new tab

You could use a print stylesheet, but this will affect all print functions.
You could try having a print stylesheet externalally, and it is included via JavaScript when a button is pressed, and then call window.print(), then after that remove it.

I have a simple request for you brainies today. What i am trying to do is to activate a pop-up inside PHP tags. I have tested to see if the pop-up works by itself, and it does. My problem is the button, i have used the same setup elsewhere, but this time no cigar. I have also tried echoing the button inside the PHP tags but nothing happens.
My code:
<!doctype html>
<html lang="en">
<head>
<meta charset="utf-8" />
<link rel="stylesheet" type="text/css" href="Lib\JqueryUIcss.css">
<script src="Lib\Jquerylib.js"></script>
<script src="Lib\JqueryUI.js"></script>
</head>
<body>
<button type=" button" class="LeButton"> Clicky Clicky!</button>
<?php
if(isset($_POST['LeButton'])){
echo'<script> $(function() { $( "#dialog" ).dialog(); }); </script>';
echo'<div id="dialog" title="Basic dialog">';
echo'<p>Image:</p>'; </div>';}
?>
</body>
</html>
I tried specifying it as a function aswell and added onclick() to the button to call that function, nothing happend either. Mind that this is the first time i am ever using Javascript/jQuery.
I (kindly) lauched a bit about the echo <script> part.
Allow me to write you a piece of code, with explanation and documentation:
HTML button:
<button type="button" id="LeButton" class="LeButton"> Clicky Clicky! </button>
&
<div id="dialog" title="Basic dialog" style="visibility:hidden"><p>Image:</p> <img src="http://placehold.it/50x50" alt="Placeholder Image" /></div>
Explanation:
Your button needs an id value. Which is called 'LeButton' in this example.
Documentation:
https://www.w3schools.com/tags/att_id.asp
jQuery part:
<script>
jQuery(document).ready(function() {
/**
* #version 1.0.0.
*
* Do magic on button click 'LeButton'
*/
$("#LeButton").click(function() {
$("#dialog").css("visibility", 'visible'); // make the div visible.
$("#dialog").dialog(); // Post here your code on forexample poping up your modal.
});
});
</script>
Explanation:
Your tag can be placed on the bottom of your page. Your browser will 'read' the whole page. By saying '(document).ready', your script will be executed once the page has been red by your browser.
For the '.click' part it's a jQuery function you can use. So which
means: once id attribute 'LeButton' (#) is clicked, jQuery will
execute a function, which will alert text in this case.
Documentation:
https://api.jquery.com/click/
Note: Make sure you have jQuery included/enabled.

Note from Simon Jensen:
You should elaborate that the Class-attribute is for styling and the
Id-attribute can be for whatever code or identifying purposes and are
unique. Therefore should people be careful with styling with the
Id-attribute as things might conflict at some point. The ID-attribute
is used to interact with the "#LeButton" attribute.
The PHP can't be run from the client. If you want the dialog to be shown onclick of the button, you must send the element before it's clicked, at the moment when it is sent to the client. You should have the dialog element hidden until the user clicks the button. It could be something like:
<!doctype html>
<html lang="en">
<head>
<meta charset="utf-8" />
<link rel="stylesheet" type="text/css" href="Lib\JqueryUIcss.css">
<script src="Lib\Jquerylib.js"></script>
<script src="Lib\JqueryUI.js"></script>
</head>
<body>
<button type=" button" class="LeButton" onclick="$('#dialog').dialog()"> Clicky Clicky!</button>
<div id="dialog" title="Basic dialog" style="display:none">
<p>Image:</p>
</div>
</body>
</html>
You could also change the onclick attribute to a script in the head like this:
<script>
$(function() {
$(".LeButton").click(function() {
$('#dialog').dialog();
});
});
</script>
I recommend you to change the class of the button for an id, and then using #LeButton instead of .LeButton
You can handle this on the client-side without the need to use PHP to do so you need to give your button a unique identifier so whenever the button is clicked you can open the dialog using a simple evenlisener like so:
var dialog = $( "#dialog-form" ).dialog({
autoOpen: false,
height: 400,
width: 350,
modal: true,
close: function() {
// do stuff here whenever you close your dialog
}
});
document.getElementById('my-button').addEventListener('click', function () {
dialog.dialog('open');
});
#dialog-form {
background-color: #ccc;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jqueryui/1.12.1/jquery-ui.min.js"></script>
<button type=" button" id="my-button" class="LeButton"> Clicky Clicky!</button>
<div id="dialog-form">
Name: <input><br/>
Password: <input type="passowrd">
</div>
<!doctype html>
<html lang="en">
<head>
<meta charset="utf-8" />
<link rel="stylesheet" type="text/css" href="Lib\JqueryUIcss.css">
<script src="Lib\Jquerylib.js"></script>
<script src="Lib\JqueryUI.js"></script>
</head>
<body>
<form action="index.php" method="POST" enctype="multipart/form-data">
<input type="hidden" name="LeButton" value="an_arbitraty_value">
<input type="submit" class="LeButton">
</form>
<?php
if(isset($_POST['LeButton'])){
echo'<div id="dialog" title="Basic dialog">';
echo'<p>Image:</p></div>';
}
?>
</body>
</html>
When you load the html page $_POST['LeButton'] is not set. Therefore the intended dialog box wil not be generated in the page. In order to have $_POST['LeButton'] set, you should pass it to the html page first, hence the form I added.
Alternatively you could go for a full javascript solution like so:
<!doctype html>
<html lang="en">
<head>
<meta charset="utf-8" />
<link rel="stylesheet" href="https://code.jquery.com/ui/1.12.1/themes/base/jquery-ui.css">
<style>
.hidden { display: none }
</style>
<script src="https://code.jquery.com/jquery-1.12.4.js"></script>
<script src="https://code.jquery.com/ui/1.12.1/jquery-ui.js"></script>
</head>
<body>
<button type=" button" class="LeButton" onclick="showDialog();">
Clicky Clicky!
</button>
<div id="dialog" title="Basic dialog" class="hidden">
<p>
This is the default dialog which is useful for displaying information.
The dialog window can be moved, resized and closed with the 'x' icon.
</p>
</div>
<script>
function showDialog() {
$( "#dialog" ).dialog();
};
</script>
</body>
</html>
Aka: why are <div></div> and <div /> not equivalent to each other?
Consider the following HTML + js:
setTimeout(function() {
document.getElementById("message2").innerHTML = "blah";
}, 1000);
<html>
<head>
<title>Test</title>
</head>
<body>
<div id="message2" />
<div id="message1" >Hello</div>
</body>
</html>
As you can see, when executing the snippet, first "Hello" is shown, and briefly afterwards, "Hello" disappears (*) and "blah" is shown. (I.e. the innerHTML of message2 was changed, and, as a side-effect, message1 disappeared.)
(*) I checked this on two different browsers (Linux/FF and Mac/Safari), so I'm quite confident this is not a browser-specific issue.
If, on the other hand, message2 is expanded to opening/closing tags, then changing its innerHTML won't affect message1:
setTimeout(function() {
document.getElementById("message2").innerHTML = "blah";
}, 1000);
<html>
<head>
<title>Test</title>
</head>
<body>
<div id="message2" ></div> <!-- notice that it was expanded -->
<div id="message1" >Hello</div>
</body>
</html>
Questions:
Why does the other div disappear in the first case?
Why do the "compact" and the "expanded" form have different effects? (I thought they were fully equivalent.)
This div <div id="message2" /> is not closed as you think it is. Here is a list of HTML's self closing tags. Note that div is not one of them.
See this:
setTimeout(function() {
document.getElementById("message2").innerHTML = "blah";
}, 1000);
<html>
<head>
<title>Test</title>
</head>
<body>
<div id="message2" >
<div id="message1" >Hello</div>
</div>
</body>
</html>
So in your second snippet you just change innerHTML of the first div, while second just sits there.
I tried to do a simple slider but that did not work, so i am copying one of code cademy, but it still qont work.
I have used 4 different browsers all have the same problem, i can type in the box but wont post, and show below.

});
};
THANK YOU ALL, this has been corrected and it now works :)
val is a jQuery function ... you need () to invoke it so it returns the value of element. As your code stands now you are trying to set a function object as text.
You are also using incorrect selectors $('btn') and $('status-box') which are looking for non existent tags <btn> and <status-box>.
Add dot prefix for both to represent class:
$('.btn') and $('.status-box')
As well as what's been mentioned in the other answer, I don't believe your main method is ever called. If it isn't called then the event handler isn't going to be attached.
The main method would be easier set up via jquery, so instead of:
var main = function() {
$('btn').click(function() {
var post = $('status-box').val
$('<li>').text(post).prependTo('.posts');
});
}
Just do:
$(function() {
$('btn').click(function() {
var post = $('status-box').val
$('<li>').text(post).prependTo('.posts');
});
});
Alternatively you could adjust your body tag as follows:
<body onload="main()">
Placing a tab container on titlepane looks weird in any browser but if I use the dojo v1.6 it appears perfectly. Am I doing something wrong here while porting code to 1.8.4 Or something broken in later versions?
Please change the dojo version in this code and see the difference.

Two problems. First, the code has TitlePane inside of a BorderContainer, but TitlePane is not designed to reside inside of layout widgets:
It extends ContentPane but since it isn’t used inside other layout widgets
Second, as written, the TabContainer inside the title pane needs an absolute height, not relative. You can get away with a relative height for TabContainers inside of BorderContainers (or other layout widgets), because BorderContainer calculates the absolute height for you. Since TitlePane does not provide that calculation, you must specify an absolute height...
or, you can tell TabContainer not to do its own layout with "doLayout=false":
<!DOCTYPE html>
<html>
<head>
<link href='//ajax.googleapis.com/ajax/libs/dojo/1.9.1/dijit/themes/claro/claro.css' rel='stylesheet' type='text/css' />

<div data-dojo-type='dijit/layout/ContentPane' data-dojo-props='title:"Tab 1"'>Hi!</div>

require(['dojo/ready', 'dojo/parser'], function (ready, Parser) {
ready(function () {

});
});
</script>
</body>
</html>
You can replace the data-dojo-props on the TabContainer with style='height:100px;' and get a similar effect. The only difference is that doLayout false uses the auto height from the contained content, while height:100px gives you a static height.
First off here is the code!
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">

window.MyMooWMD.start();
});
</script>
</body>
</html>
Bam!
My problem is this, it doesn't work like the example at mooWMD tutorial all I get is an empty text area with the wmd.css style applied to it. I cant figure out what I could be doing wrong. All the file locations are correct but i get 'mooWMD' is undefined. I am at a loss any and all suggestions are appreciated.
The problem (for later generations) is IE does not accepts the following syntax:
{
att1: 'value',
att2: 'value'
}
Where other browsers do.
I changed it to
{
'att1': 'value',
'att2': 'value'
}
And it is fine now.
(using the mailing list would have gotten my attention earlier)
The code in the local javascript tag executes as soon as the tag is processed. This may happen before moowmd.js has completed loading.
Wrap the code in a function:
<script type="text/javascript">
function loaded() {
var MyConfig = [
{
input: 'id-uno',
postfix: '-uno'
}];
window.addEvent('domready', function() {
window.MyMooWMD = new mooWMD.WMD(window.MyConfig);
window.MyMooWMD.start();
});}
</script>
Then add an onload handler to your body tag:
<body onload="loaded();">
The onload handler will not fire until all the javascript, images, css, etc have loaded.
<head>
<title>some title </title>
<link rel="stylesheet" type="text/css" href="Content/wmd.css" />
<script type="text/javascript" src="Scripts/showdown.js"></script>
</head>
<body>
<div class="main">
<div id="wmd-editor" class="wmd-panel">
<div id="wmd-button-bar">
</div>
<textarea id="wmd-input"></textarea>
</div>
<div id="wmd-preview" class="wmd-panel">
</div>
<div id="wmd-output" class="wmd-panel">
</div>
</div>
<script type="text/javascript" src="Scripts/wmd.js"></script>
</body>
The root of the problem ended up being the moowmd editor just didn't work consistently in IE. The reason I was tiring to go with the moowmd was I liked how he handled setting up multiple editors. I ended up just switching to stackoverflow's branch of wmd it is working well so far.
