Button to Copy a Text Box - javascript

I need a simple script that gives me a button that when clicked will copy the contents of a text input box to the clipboard. Or it could be a script that when you click on the text input box, automatically copies the contents to the clipboard and displays a "Copy" message next to the text input box.
I've seen them all over the web, but can't find the code for one now.

This example uses jQuery:
Assuming an input box with an id of foo, and a button with an id of clickme, here's how I'd do it:
var inputText = "";
$("#clickme").click(function() {
inputText = $("#foo").val();
});
// inputText now has the input box's value
Edit:
After your clarification, I now understand what you are trying to do. Unfortunately, flash 10 broke most of the methods to do this. However, some great people wrote ZeroClipboard, which is fully compatible with flash 10 and makes it really easy to accomplish this task. Their wiki explains usage.

Copy to clipboard and send keycode

The function from my Softphone (VoIP Phone on my PC) is, when I copy a phone number in clipboard and then I press "Pause" (German Keyboard), the softphone dials the number. I have created which help from some code examples in internet a copy function, which copied from a field in my database the phone number in the clipboard, when I press a button. It works perfectly. Now I wish to dials the number immediately and therefore it is necessary, the button do not copy the number only, but rather simulated the key press "Pause" after the copy.
Unfortunately my knowledge in PHP is ok, but in JavaScript it is very very bad. And therefore my request is for help me in this case.
Thank you very much in advance
Here is my script:
// in $Mobil01 is the phone number
]
<button class=copy-button id=buttonM01><i class=fa fa-copy style=font-size: 20px;></i></button>
<script>
var telefonM01 = document.getElementById("telefonM01")
var buttonM01 = document.getElementById("buttonM01");
buttonM01.addEventListener("click", function (eventM01) {
eventM01.preventDefault();
telefonM01.select();
document.execCommand("copy");
});
</script>
The select event occurs only when a text is selected (marked) in a text area or a text field. So, for working with this you will have to set the element with the id telefonM01 as some input or textarea element.
An alternate way of copying text is to attach the text with the button to copy.

Javascript issue- Cannot Submit form after document.getElementById

document.getElementById("hs-search-origin").value = myloc;
I am successfully writing the value in a Text Box
The text box is attached to a searchbox and up on clicking the search button, search is not happening.
I have to edit the textbox, like remove character or add character in the text box, to make it work.
For Ex:
myloc="i love stackoverflow";
document.getElementById("hs-search-origin").value = myloc;
The text box shows the value i.e "i love stackoverflow" but on clicking the button, nothing happens.
I have to either edit the text in the textbox and then click on search to make it work. What is the issue, any guess
You have some code which runs (and does a search) when the user changes the value of the text box.
It doesn't run when you change the value with JavaScript.
You need to call that code explicitly when you want it to fire in response to something else than the user typing.

Detecting non tagged textarea or input fields

I made a Chrome Extension that allowed me to change certain characters if certain keystroke combinations were made to any input or text area field. It works fine as long as what I am typing in is a input or textarea field. However, when I go to a site like FaceBook and try their post or comments field, it doesn't work because those fields somehow don't have textarea tags in their source.
Here is what I currently use.
document.activeElement.onkeydown = function(){ getCharKeyDown(event) };
document.activeElement.onkeyup = function(){ getCharKeyUp(event) };
What would I need to do, to detect if a user is typing in a textarea that doesn't seem to actually be a text area (in plain JavaScript please)?
Thanks.
Thanks to epascarello, I think I've got it sorted. After a bit of reading about the HTMLElement.contentEditable property, I came across Document.execCommand() which seems to take care of all editable elements.
This was the main change I made
function insertAtCursor(myField, myValue) {
document.execCommand('insertHTML', false, myValue);
}
and now I am able to run my functions wherever.

Keeping text entered into a textarea visible at all times

When entering text into a textarea manually, it remains visible at all times. However I'm using a simple javascript function to enter some text when an icon on the page is clicked.
onClick="addline('xyz')
function addline(sometext)
if(sometext == "xyz")
{
document.getElementById('thearea').value = "Hello world!\n";
}
The problem is, when text entered this way reaches the bottom of the textarea, it disappears from view and the scrollbar just lengthens.
My question is, is there any way to keep the text visible at all times? Thanks.
Thank you for referring me to a similar request for assistance. I have done what I thought was a comprehensive search here and on other web sites to a solution to this issue before posting. Unfortunately, the code suggested doesn't make any difference, the text added using the above function remains hidden in my textarea until the scrollbar down arrow is clicked.

How to prevent deselection of selected text on blur (focus lost) in html

I have been doing research on this simple sounding issue for a couple of days and I have not seen any result.
In a nutshell my problem is as follows: I would like to select text in a some input field, move focus to another field (or generally speaking some other element), but not lose my selected text.
Such a situation could correspond to a use-case in which I select text in a field, right-click and display a custom popup menu, but do not wish to lose focus of selected text, because I want to do some operations on the previously selected text.
A small code test sample would be (for my initial simple scenario - here I am forcing text selection when the second input field gains focus):
<html>
<head>
<script src="http://code.jquery.com/jquery-latest.js"></script>
</head>
<body>
<input type="text" id="text1" size="20" value="Test1"/>
<input type="text" id="text2" size="20" value="Test2"/>
<script>
$('#text2').focus( function (evt) {
var target = $('#text1')[0];
target.select();
console.log('active/focused element: ' + document.activeElement.id);
});
</script>
</body>
</html>
I have been searching SO and web for a solution to this and have not seen much if any help.
I am not sure this is even really possible (due to the link between blur and selection lost and focus and selection). I have seen a style property called preventDeselect, in another SO answer - this does not work and I have not even such documentation or browser support for this.
I am quite struggling with this and would appreciate some help: even saying I can't do this at all or maybe some ways to go.
UPDATE:
Just for the record, my user scenario, which refers to text selection and context menu, is a common one (it slipped my mind to mention): just select some text in this page (or in an input type field) and right click to get the browser's default context menu - my scenario is different in that i want to use a custom menu, but with similar behavior to the browser's context menu - which normally allows to select some text, cut/copy the selection, navigate within the context menu without losing the selected text. So I think it should be possible somehow :) to do all these things with a context menu and still have your selection.
Attempting to answer this part of your question:
Such a situation could correspond to a use-case in which I select text
in a field, right-click and display a custom popup menu, but do not
wish to lose focus of selected text, because I want to do some
operations on the previously selected text.
For this use-case, I created a quick fiddle: http://jsfiddle.net/4XE9a/1/
Note: Am using the same getSelection function from #David's answer.
If you select any text and then right-click on the input, a custom popup menu appears. Click "option 1". You will find that the selection is not lost even though the focus has shifted to that anchor tag.
However, for the second part of your question regarding focus shifting to another textbox, #David's answer suffices.
Update: (after your comments)
Please see this updated fiddle: http://jsfiddle.net/783mA/1/
Now, when you select some text and right-click on the input it will show the custom popup menu with three options. Use tab to navigate and press space or click on the highlighted option. (Due to paucity of time I could not implement up/down arrow keys, but the concept remains the same)
This demonstrates your question in the comment that the selection is still not lost while navigating the menu.
Note: You are wanting to visually keep the selection highlight and not lose the selection while clicking anywhere else. Please note that this is not possible because text selection behavior is OS implemented. Browser, html etc do not play a role here. The text selection is lost as soon as you click anywhere outside the context of selection. This is because the system starts expecting a new selection as soon as you click anywhere outside. However, controls without text surface are exempt. Button, scrollbar arrows etc will not cause selection to lose.
To view this behaviour, in the fiddle, select some text and then click any dropdown on the left pane. The text selection is not lost, even visually for that matter.
This is why in the new fiddle above, I purposely used buttons to demonstrate.
You can save each selection in an interval, then retrieve it when you like. Here is an example that pulls the selection when the input has focus and clears the interval on blur:
function getSelection(elm) {
var start = elm.selectionStart;
var end = elm.selectionEnd;
return elm.value.substring(start, end);
}
$('input').focus(function() {
var self = this;
$(this).data('interval', setInterval(function() {
$(self).data('selection', getSelection(self));
},20));
}).blur(function() {
clearInterval($(this).data('interval'));
});
Now you can stuff like:
$('#text2').focus(function() {
console.log('selection in #text1 was: '+$('#text1').data('selection'));
});
