I am trying to duplicate Expanding Text Areas Made Elegant
Basically it explains how we can achieve something like fb comment box, where its size increases as text files the textarea.
I have this in my index.html:
<html>
<head>
<link rel="stylesheet" type="text/css" href="test.css">
<script src="test.js"></script>
</head>
<body>
<figure>
<div class="expandingArea">
<pre><span></span><br></pre>
<textarea></textarea>
</div>
</figure>
</body>
</html>
And my test.js looks like:
This doesn't really works.
However if I move everything inside the js file to a script tag inside body then it works fine. So my index file would look like:
<html>
<head>
<link rel="stylesheet" type="text/css" href="test.css">
</head>
<body>
<figure>
<div class="expandingArea">
<pre><span></span><br></pre>
<textarea></textarea>
</div>
</figure>
<script>
function makeExpandingArea(container) {
var area = container.querySelector('textarea');
var span = container.querySelector('span');
if (area.addEventListener) {
area.addEventListener('input', function() {
span.textContent = area.value;
}, false);
span.textContent = area.value;
} else if (area.attachEvent) {
// IE8 compatibility
area.attachEvent('onpropertychange', function() {
span.innerText = area.value;
});
span.innerText = area.value;
}
// Enable extra CSS
container.className += ' active';
}var areas = document.querySelectorAll('.expandingArea');
var l = areas.length;while (l--) {
makeExpandingArea(areas[l]);
}
</script>
</body>
</html>
You're not actually using onload
Your formatting is so messed up it's hard to tell, but your init code is in a while loop at the bottom after your onload function.
When you include it in the <head> it runs before any elements exist. That's why the position of it matters.
In your browser(I recommend Chrome for testing) open up the developer tools(via right click and selecting inspect element) and make sure your test.js file's path is correct. Do this by selecting the 'Sources' tab on the top of the developer tools window and then selecting the test.js file on the list of sources.
I also consider it best practice to load your js files at the bottom of your web documents(before the last body tag) to guarantee they load AFTER your dom elements load.
try this in your code:
I have used inside a table andapply a css class "form-control". The properties of this text areas are in side tag in side
html code:
<html>
<body>
<table>
<tr>
<td>Description:</td>
<td><textarea name="DESCRIPTION" id="DESCRIPTION" class="form-control"></textarea></td>
<td></td>
</tr>
</table>
//css-code required inside html:
<style>
textarea.form-control {
height: auto;
resize: none;
width: 300px;
}
</style>
</body>
</html>

the problem is i can not add an style to the code and make the images appear in different positions to make a layout.
can anyone here help me?

<title> COOPER BLACK </title>
<link rel="stylesheet" type="text/javascript" href="style.css" media="screen">
</head>
<div class="container">
<script type="text/javaSCRIPT">
var i = 1
function imageClick() {
if (! this.alreadyClicked)
{
addimage();
counter();
this.alreadyClicked = true;
}
}
function addimage() {
var img = document.createElement("img");
img.src = "images/d"+i+".jpg";
img.onclick = imageClick;
document.body.appendChild(img);
}
function counter() {
i = i + 1
}
</script>
<div class="first">
<input class="first" type="image" src="images/d0.jpg" onclick="imageClick();">
</div>
</div>
Try setting the class attribute this way
img.setAttribute("class", "YourClassName");
Then apply the style to YourClassName in a CSS file/style tag. (Might also want to call the script after you load the CSS) Like so
.YourClassName { /* style here */ }
Edit:
You can also check if the elements are rendered well (the HTML tags have the class names and onClick methods) using the console (press F12 on the page)
I have been writing ColdFusion/JS for 15 years, and this has me totally baffled!
I can run javascript to do anything inside my CFLayoutArea, but it will not let me display or change the styles in JS.
When you load the dashboard.cfm page in the layoutarea, it gives an javascript error anytime you try to change or reference (display) any style attribute related to the div element.
Here is the calling page:
function dashBoard() {
ColdFusion.navigate('dashboard.cfm','content');
}
<cflayout>
<cflayoutarea>
<cfdiv id="content" />
</cflayoutarea>
</cflayout>
Here is dashboard.cfm:
<html>
<head>
<style>
#szliderbar1{
width:37%;
}
</style>
<script>
displayProgress = function() {
var tttt = document.getElementById('szliderbar1');
alert(tttt.style.width);
}
</script>
</head>
<body>
<div id="szliderbar1"> hey
</div>
</body>
</html>
<cfset ajaxonload("displayProgress")>
I have successfully created an Ace editor before, but recently I am making a website called CodeProjects, and I want to put an Ace editor in. Whenever I try, it only shows the text function foo(items) {
var x = "All this is syntax highlighted";
return x;
}. On the page http://ace.c9.io/#nav=embedding&api=ace, it says you only need the code:
<!DOCTYPE html>
<html lang="en">
<head>
<title>ACE in Action</title>
<style type="text/css" media="screen">
#editor {
position: absolute;
top: 0;
right: 0;
bottom: 0;
left: 0;
}
</style>
</head>
<body>
<div id="editor">function foo(items) {
var x = "All this is syntax highlighted";
return x;
}
</div>
<script src="/ace-builds/src-noconflict/ace.js" type="text/javascript" charset="utf-8"></script>
<script>
var editor = ace.edit("editor");
editor.setTheme("ace/theme/monokai");
editor.getSession().setMode("ace/mode/javascript");
</script>
</body>
but when I try to embed it (or even just make the editor, not the site), again, it only shows function foo(items) { var x = "All this is syntax highlighted"; return x; }
Any suggestions?
it also says to copy files into your project. If you don't want to do that, include script from cdn
<script src="//cdn.jsdelivr.net/ace/1.1.01/min/ace.js"
type="text/javascript" charset="utf-8"></script>
see http://jsbin.com/ojijeb/165/edit
You need to put the content outside of the editor div [or fetch the content on page load using AJAX]. Either way, you then load the content into the editor with JavaScript: editor.setValue("hello world");.
To set the height of the editor, you resize the div it lives in, then call the editor's resize method.
var div = document.getElementById('editor');
div.style.height = some_multiple_of_the_line_height_for_tidiness;
editor.resize();
In my experience, you need to change div to pre. Just using pre instead of div in following way should solve your problem.
<pre id="editor" >
</pre>
Ok, I saw this tutorial http://css-tricks.com/dynamic-page-replacing-content/, pretty cool actually!
My problem is as flows, I have a page that not only has contents but also specific javascript content, and css. Is there a way to load those files dynamically, would It be correct? What if I have a hard coded on the page, how would I load that css/js script?
Thanks in advance.
[Edit]
Some code:
<html>
<head>
<script type="text/javascript" src="..."></script>
<script type="text/javascript">
$(document).ready(
alert('the document has finished loading!!');
// do form validation and send
)
</script>
</head>
<body>
Please Full the necesary (*) Fields
<form method="post" action="testing.php" id="test" name="test">
(*)<input type="text" name="fullname" />
<input type="submit" value="Send" />
</form>
</body>
</html>
Let's say I wanna load that page dynamicaly and load the validation and related javascript placed on header. Should load files readeing the headers? how can I know which one had been already loaded?
Thanks for the answers!

You can change the CSS stylesheet dynamicly by changing the href attribute.
Javascript can also be loaded dynamicly by loading the script self into the div or by writing the script src to it.
Here an simple example:
CSS 1:
body {
background: black;
color: #333;
}
CSS 2:
body {
background: red;
color: white;
}
HTML:
<html>
<head>
<title>Test page</title>
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js" type="text/javascript"></script>
<link href="/includes/css/test1.css" rel="stylesheet" type="text/css" />
</head>
<body>
<h1>TEST!!!!!</h1>
<div id="code"></div>
<input type="button" id="but" value="click!" />
<script>
var css = 1;
$('#but').click(function() {
if(css == 1) {
css = 2;
} else {
css = 1;
}
$('link').attr('href', '/includes/css/test' + css + '.css');
//test();
test2();
});
function test2() {
$('#code').html("<script>alert(\"It works!!!\");<\/script>");
//Or parse the src
//$('#code').html("<script src=\"js/your_js_file.js"><\/script>")
}
</script>
</body>
</html>
So it's posible to load CSS and Js into your page after the page is loaded.
Hope this helps!
I have a "print" button on index.html. What code do I need to print the print.html file? I mean, when I press the button from index.html, print the page print.html.
function closePrint () {
document.body.removeChild(this.__container__);
}
function setPrint () {
this.contentWindow.__container__ = this;
this.contentWindow.onbeforeunload = closePrint;
this.contentWindow.onafterprint = closePrint;
this.contentWindow.focus(); // Required for IE
this.contentWindow.print();
}
function printPage (sURL) {
var oHiddFrame = document.createElement("iframe");
oHiddFrame.onload = setPrint;
oHiddFrame.style.visibility = "hidden";
oHiddFrame.style.position = "fixed";
oHiddFrame.style.right = "0";
oHiddFrame.style.bottom = "0";
oHiddFrame.src = sURL;
document.body.appendChild(oHiddFrame);
}
Then use
onclick="printPage('print_url');"
I think you're looking for window.print()
Update
Just noticed you've specified file names in there and that you want to print print.html when a button on index.html is clicked. There's no built-in way to do this (in the sense that you can't pass any arguments to window.print() indicating the document to print). What you could do is load the document to print into an iframe or open a new window and on load, invoke window.print() on that container.
Here are some forum posts and web pages that talk about the same thing:
http://www.highdots.com/forums/javascript/printing-another-web-file-present-274201.html
http://www.webmasterworld.com/javascript/3524974.htm
http://www.felgall.com/jstip29.htm
Update 2
Here's some quick-and-dirty code - note that this will only work if both your pages are in the same domain. Additionally, Firefox seems to fire the load event for an empty iframe also - so the print dialog will be displayed immediately on load, even when no src value was set for the iframe.
index.html
<html>
<head>
<title>Index</title>
<script src="http://code.jquery.com/jquery-1.4.3.min.js"></script>
<script>
$(document).ready(function(){
$('#loaderFrame').load(function(){
var w = (this.contentWindow || this.contentDocument.defaultView);
w.print();
});
$('#printerButton').click(function(){
$('#loaderFrame').attr('src', 'print.html');
});
});
</script>
<style>
#loaderFrame{
visibility: hidden;
height: 1px;
width: 1px;
}
</style>
</head>
<body>
<input type="button" id="printerButton" name="print" value="Print It" />
<iframe id="loaderFrame" ></iframe>
</body>
</html>
print.html
<html>
<head>
<title>To Print</title>
</head>
<body>
Lorem Ipsum - this is print.html
</body>

You can use the JQuery printPage plugin (https://github.com/posabsolute/jQuery-printPage-plugin). This plugin works fine and you can simply print an external html page.
Example:
<html>
<head>
<title>Index</title>
<script src="http://www.position-absolute.com/creation/print/jquery.min.js" type="text/javascript"></script>
<script src="http://www.position-absolute.com/creation/print/jquery.printPage.js" type="text/javascript"></script>
<script>
$(document).ready(function() {
$(".btnPrint").printPage();
});
</script>
</head>
<body>
<input type="button" id="printerButton" name="print" value="Print It" />
<p><a class="btnPrint" href='iframe.html'>Print!</a></p>
</body>
</html>
