Creating a "Copy button"

Well, as I was searching on the internet for some basic codes to examine - I found this one. A simple code which is supposed to copy the selected text. As i am a complete newbie in JS, I check the meaning of the methods that I didn't understand - and rewrited the code, as i make a few adjustments.
And still the code is not working and If someone can explain - this part ""copyit(this.form.select1)"" - Even though I kind of understand "this" - i am not able to understand what is doind here
function copyit(theField) {
var selectedText = document.getSelection();
if (selectedText.type == 'Text') {
var newRange = selectedText.createRange();
theField.focus();
theField.value = newRange.text;
} else {
alert('select a text in the page and then press this button');
}
}
</script>
<form name="it">
<div align="center">
<input onclick="copyit(this.form.select1)" type="button" value="Press to copy the highlighted text" name="btnCopy">
<p>
<textarea name="select1" rows="4" cols="45"></textarea>
</div>
</form>
This is the original code - and it is not working either
<SCRIPT LANGUAGE="JavaScript">
function copyit(theField) {
var selectedText = document.selection;
if (selectedText.type == 'Text') {
var newRange = selectedText.createRange();
theField.focus();
theField.value = newRange.text;
} else {
alert('select a text in the page and then press this button');
}
}
</script>
And in the body of your web page, add the following where you want the text to appear:
<form name="it">
<div align="center">
<input onclick="copyit(this.form.select1)" type="button" value="Press to copy the highlighted text" name="btnCopy">
<p>
<textarea name="select1" rows="4" cols="45"></textarea>
</div>
</form>

onclick="copyit(this.form.select1)"
executes the copyit() function and passes a variable which is later named theField. The variable that is passed is this.form.select1 which is a textarea with ID select1 which is located in the same form as the input you're clicking hence the this.form.
As to why your code isn't working - you should include here the original code before your adjustments. You probably deleted/changed something you shouldn't have.

I'm not sure what you're asking. Are you asking to, when someone clicks on any button/div, it copies a text you want for his clipboard? If no, ignore my comment, if yes, i'll explain:
First place, where should an user click?
<a class="btn" CopydivFunction(#text)">CLICK ME TO Hello.</a>
Now, add the function with JS.
function copyToClipboard(element) {
var $temp = $("<input>");
$("body").append($temp);
$temp.val($(element).text()).select();
document.execCommand("copy");
$temp.remove();
}
Now, place the text you want somebody to copy (hide it):
<h1 id="text" class="hidden">some text. This part won't be seen because of the hidden class, and this is the text that will be copied to your clipboard.</h1>
Place display:none on css:
#text{
display:none;
}
I think you have to add that, so nobody sees it.
And that should be it, click the <a> and you get the text in the h1#text

Replacing content within a div with an iframe

I am trying to replace the content of a div with an iframe that allows the user to input a URL to display another page. I will, ideally, add another button next to the Change URL button that links to a specific page.
However, I cannot get this code to work. I can get the div to be replaced with text and some html. But the iframe code won't load when I put this in. I am suspecting it's due to the quotation marks.
I am a bit of a novice at javascript/JQuery so any help with this will be greatly appreciated.
Here is what I have going for the code below.
<style>
#target {
width: 200px;
height: 340px;
}
</style>
<script>
$(function load($){
var $iframe = $('#target'),
$change = $('#change'),
$url = $('#url');
$change.click(function url() {
$iframe.attr('src', $url.val());
});
});
document.getElementById("c_emot").innerHTML = "<iframe id="target" src="/"></iframe><br>
<input id="url" type="text"><br>
<button id="change" type="button">Change URL</button>";
</script>

Your quoted string is all wrong. Try this:
document.getElementById("c_emot").innerHTML = '<iframe id="target" src="/"></iframe><br>
<input id="url" type="text"><br><button id="change" type="button">Change URL</button>';
for reference: http://www.javascripter.net/faq/quotesin.htm
Also, your click event is not being bound to the button after the button is created. You can make it persistent on the button's container like this:
$('#c_emot').on('click', '#change', (function(){
$('#target').attr('src', $('#url').val());
});
And if youre going to mess with the DOM, you have to be sure that the element you want to manipulate has already been created when your code is run:
$(document).ready(function(){
// put all your code here
});
but maybe you should be creating elements instead of dumping markup into the container:
document.onreadystatechange = function () {
if(document.readyState == "complete") {
var container = document.getElementById("c_emot");
var iframe = document.createElement('iframe');
iframe.src = "/";
container.appendChild(iframe);
var input = document.createElement('input');
input.id = "url";
input.type = "text";
container.appendChild(input);
var button = document.createElement('button');
button.id = "change";
button.innerHTML = "Change URL";
button.addEventListener('click', function() {
iframe.src = input.value;
});
container.appendChild(button);
}
}
Not sure if that event listener will work, got to try it and see :)
Have you tried just doing it without messing around with the DOM?...
<iframe name="urlbox"></iframe>
<input type="text" id="urlinput" />
<button onclick="window.open(document.getElementById('urlinput').value, 'urlbox')">Navigate!</button>
Most browsers wont let you navigate the iframe to a different domain for security anyway, so maybe this is all for nothing.

This demo has 2 features:
Using the text input, user can enter a URL to change the src of the iframe.*
This is possible by using this function:
function changeSrc(src) {
var iframe = document.getElementById('site');
site.src = src;
}
*Be aware that not all sites are iframe friendly, so expect some sites that my function will simply not work for.
Notice the links to various sites. Their behavior has been alter--rather than jumping to the site, it opens the site within the iframe.
Each link is a normally constructed anchor element <a> with one exception. It's value for their attribute target is site.
site is the name of the iframe. When an anchor has target="name of iframe"` the anchor opens the site within that targeted iframe.
This must be the iframe's name attribute not the iframe's id.

Getting blank page sent to printer using a hidden div method

I am using a code snippet that I found to display a multipage form using visibility hidden.
There is a very good possibility that all of my problem stems from this method. That resource was from here:
http://www.devx.com/webdev/Article/10483/0/page/2
It is a fairly straightforward way to display multiple pages of a form...it probably was never intended to be able to allow printing.
<html>
<head>
<script type="text/javascript" src="jquery-1.10.2.min.js"></script>
<script language="JavaScript">
$.getScript("printThis.js", function(){
});
var currentLayer = 'page1';
function showLayer(lyr){
hideLayer(currentLayer);
document.getElementById(lyr).style.visibility = 'visible';
currentLayer = lyr;
}
function hideLayer(lyr){
document.getElementById(lyr).style.visibility = 'hidden';
}
function showValues(form){
var values = '';
var len = form.length - 1; //Leave off Submit Button
for(i=0; i<len; i++){
if(form[i].id.indexOf("C")!=-1||form[i].id.indexOf("B")!=-1)
continue;
values += form[i].id;
values += ': ';
values += form[i].value;
values += '\n';
}
alert(values);
}
</script>
<style>
body{
font: 10pt sans-serif;
}
.page{
position: absolute;
top: 10;
left: 100;
visibility: hidden;
}
</style>
</head>
<body>
<form id="multiForm" action="App1.php" method="POST" action="javascript:void(0)" onSubmit="showValues(this)" id="app">
<div id="page1" class="page" style="visibility:visible;">
Applicant Name: <input type="text" size="50" name="name1" >
</form>
<p><input type="button" id="C1" value="Continue" onClick="showLayer('page2')"></p>
</div>
<div id="page2" class="page">
This is Page 2
<br>
<input type="button" id="B1" value="Go Back" onClick="showLayer('page1')">
<input type="button" id="B2" value="Print App" onClick="$('#page1').printThis({})">
<br><br>
</div>
</form>
</body>
</html>
The "Print App" button is properly calling the printThis plugin. However, I get no content from the page1 DIV section. All that is printed is the normal header portion (Page 1 of 1) in the upper right and about:blank in lower left and date in lower right of page…no content, which with my sample file should be Applicant Name input box.
I assume that this is because the DIV for page1 is set to "hidden" while the content of page2 is being displayed. If I substitute "page2" in the button call then I get the content from page2 as expected.
So...I guess what I am after is a way to temporarily change the DIV being referenced in the printThis button call to be visible just long enough to perform the page print.
Any ideas?

I'm the plugin author - you need to incorporate the print media query into your css.
This would also help users that select file > print or control + P, as it will show all form elements.
The print media query allows you to make styling changes specifically for the printed page.
Example:
#media print {
#page1, #page2 {
display: block;
visibility: visible;
position: relative;
}
}
You include this in your css.
Additionally, based on your above code - you have css and javascript inline in your page. You should consider moving both to an external files, for maintenance and improved code standards.
printThis won't work with your current setup, because the plugin looks for the container (selector) you have specified and any linked css in the head of the document.
So for the above, you can do the following:
<!-- move all of this to the bottom of the page for performance -->
<script type="text/javascript" src="jquery-1.10.2.min.js"></script>
<script type="text/javascript" src="printThis.js"></script>
<script type="text/javascript" src="myJavascript.js"></script>
<!-- the above file is your javascript externalized, remove $.getScript, wrap in $(document).ready() -->
Then put this in your head:
<link type='text/css' rel='stylesheet' href='style.css'>
<!-- contains your css from the page, including the print media query -->

Remove print button from hard copy

With reference to this link and this, I printing a report using javascript as
<!DOCTYPE html>
<html>
<head>
<script>
function printpage()
{
var data = 'Sample Report<br />Sample Report<br />Sample Report<br />';
var data = data+'<br/><button onclick="window.print()">Print the Report</button>';
myWindow=window.open('','','width=800,height=600');
myWindow.innerWidth = screen.width;
myWindow.innerHeight = screen.height;
myWindow.screenX = 0;
myWindow.screenY = 0;
myWindow.document.write(data);
myWindow.focus();
}
</script>
</head>
<body>
<input type="button" value="Print Preview" onclick="printpage()" />
</body>
</html>
But after printing, the print button still remains at the hard copy. So how to hide the print button in hard copy when printing by using the above function?

Give your button a class, e.g. class="noprint". Then Add a stylesheet for print media to your CSS:
#media print {
/* style sheet for print goes here */
.noprint {
visibility: hidden;
}
}
Details: http://www.w3.org/TR/CSS2/media.html

I just solved this with the following css after assigning id to print button.
<style type="text/css">
#media print {
#myPrntbtn {
display : none;
}
}
</style>
And my button as follows.
<input id ="myPrntbtn" type="button" value="Print" onclick="window.print();" >
Also, you can run javascript function with the following actions...
Hide the button
Print the page using window.print();
Again Show back the button
Piece of code...
<script type="text/javascript">
function printMyPage() {
//Get the print button
var printButton = document.getElementById("myPrntbtn");
//Hide the print button
printButton.style.visibility = 'hidden';
//Print the page content
window.print()
//Show back the print button on web page
printButton.style.visibility = 'visible';
}
</script>

(IE6) insert content into iframe at current cursor position

I'm currently upgrading a WYSIWYG Rich Text Editor that was based on the DHTML Editor Control (DEC) to use the more modern editor controls in modern browsers. I'm using an iFrame with design mode turned on and a mixture of regular javascript and jquery.
One of my requirements is to insert html content (forms etc) into the iframe so that users can edit them. I have it working in FF + Chrome, but IE is proving a pain. My current code inserts the content at the start of the parent document and not the iframes, I'm using the selection.createRange() function that when used with DEC would insert the content either at the cursor if the control was selected or at the end of the document inside the editor if not.
Currently it only works when I select some text in IE. Heres my current code (apologies if it looks unformatted the firewall at work is blocking a lot of the css + js from stackoverflow), any ideas?

document.getElementById('frameEdit').contentWindow.document.open();
document.getElementById('frameEdit').contentWindow.document.close();

}

var doc = document.getElementById('frameEdit').contentWindow.document;

Make your button unselectable to stop it nicking the focus from the iframe. You can do this in IE using uneselectable="on":
<input type="button" value="OK" unselectable="on"
style="width: 80px" onclick="insertContent();">
