Displaying textarea content on click of button - javascript

I am having a text area and a button.Like this :
<textarea id="txtarea"></textarea>
<input type="button" value="add text" id="add" />
Now,what i want to do is that on click of the button that text to be displayed on the same page above this text area just like we do comment or answer a question on stackoverflow.
How this can be done ?Please help.

you can do this using javascript
add any tag before (generally div or span tag is used) textarea tag
<div id="adduserdata"></div>
<textarea id="txtarea"></textarea>
<input type="button" value="add text" id="add" onclick="showtext()" />
Javascript code would be
function showtext(){
var text = document.getElementById("txtarea");
var showarea = document.getElementById("adduserdata");
showarea.innerHTML=text.value;
}
here is working example

As what you want, thus appending to the <div> division element, I assume that you will accept this answer (as a summary to all the comments and answers above) :
<!-- This is the HTML Part -->
<div id="text"></div>
<textarea id="new"></textarea>
<input type="button" onclick="appendTextToDiv();" />
<script>
function appendTextToDiv(){document.getElementById("text").innerHTML = document.getElmentById("text").innerHTML + document.getElementById("new").value;}
</script>
This can let you simply append it to the text. Fiddle

This will do if using Jquery (and previously text will stay) :
$('.button').click(function(){
var text = $('textarea').val();
if(text!=''){
$('p').text(text);
}
});
or like this:
$('.button').click(function(){
var text = $('textarea').val();
if(text!=''){
$('<p></p>').text(text).insertBefore('textarea');
}
});
Fiddle

Copy text to clipboard from hidden input is not working in jQuery

I have the following code to copy a text to the clipboard by clicking on a Button. Text is in a Paragraph element, So I move that text to a hidden input field and then copy it to the clipboard. But this is only working if I move the text to a text field but not a hidden field. I also tried to display:none the input field, but the result is the same. (I can't set it to visibility:hidden because the space matters). How can I solve this?
$("button").on("click", function() {
var n = $("p").text();
n = $.trim(n);
$(".copied").attr("value", n).select();
document.execCommand("copy");
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<p>
This is the copied text!
</p>
<input type="hidden" class="copied"/>
<button>
COPY
</button>
<input type="text" placeholder="paste copied text here"/>
Here is the editable jsfiddle:
http://jsfiddle.net/d9a4x6vc/
You can try to change the type of the input to text before select then, and bring the type hidden back after like that.
$("button").on("click", function() {
var n = $("#copyMe").text();
$(".copied").attr("value", n);
$(".copied").attr("type", "text").select();
document.execCommand("copy")
$(".copied").attr("type", "hidden")
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<p id="copyMe">
This is the copied text!
</p>
<input type="hidden" class="copied"/>
<button>
COPY
</button>
<input type="text" placeholder="paste copied text here"/>
I had exactly the same problem recently. What I did is put that input box position as absolute and moved it off screen. Also notice that even input field width does affect result. I tried to put width and height to 0, and it didn't copy after that also.
As DavidDomain explains in answer to a similar question, you need to change your input properties to take the value.
In your case, you can try this:
$("button").on("click", function() {
var n = $("p").text();
n = $.trim(n);
$(".copied").css({
position: "absolute",
left: "-1000px",
top: "-1000px"
}).attr("value", n).attr("type","text").select();
$(".copied").attr('css','').attr("type","hidden");
document.execCommand("copy");
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<p>
This is the copied text!
</p>
<input type="hidden" class="copied"/>
<button>
COPY
</button>
<input type="text" placeholder="paste copied text here"/>

Input text value into a div?

Say I have this text box:
<input type="text" id="myText" placeholder="Enter Name Here">
Upon pressing a button, I would like to send the value entered into this div:
<div id="text2"></div>
I'm not entirely sure how to do this. Do I create a function and call it to the div? How would I do that?
Could someone clear this up for me? Thanks.
Add an onclick to your button:
<input type="button" id="somebutton" onclick="addText()">
Then write the javascript:
function addText()
{
document.getElementById('text2').innerHTML = document.getElementById('myText').value;
}
Solution using onclick event:
<input type="text" id="myText" placeholder="Enter Name Here">
<div id="text2"></div>
<button id="copyName" onclick="document.querySelector('#text2').innerHTML = document.querySelector('#myText').value" value="Copy Name"></button>
JSFiddle: http://jsfiddle.net/3kjqfh6x/1/
You can manipulate the content inside the div from javascript code. Your button should trigger a function (using the onclick event), which would access the specific div within the DOM (using the getElementById function) and change its contents.
Basically, you'd want to do the following:
<!DOCTYPE html>
<html>
<script>
function changeContent() {
document.getElementById("myDiv").innerHTML = "Hi there!";
}
</script>
<body>
<div id="myDiv"></div>
<button type="button" onclick="changeContent()">click me</button>
</body>
</html>
Mark D,
You need to include javascript to handle the button click, and in the function that the button calls, you should send the value into the div. You can call $("#myText").val() to get the text of the text box, and $("#txtDiv").text(txtToAppend) to append it to the div. Please look at the following code snippet for an example.
function submitTxt() {
$("#txtDiv").text($("#myText").val())
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input type="text" id="myText" placeholder="Enter Name Here">
<button onclick = "submitTxt()"> Submit </button>
<div id="txtDiv"> </div>
HTML could be:
<input type='text' id='myText' placeholder='Enter Name Here' />
<input type='button' id='btn' value='click here' />
<div id='text2'></div>
JavaScript should be external:
//<![CDATA[
var pre = onload; // previous onload? - window can only have one onload property using this style of Event delegation
onload = function(){
if(pre)pre();
var doc = document, bod = doc.body;
function E(e){
return doc.getElementById(e);
}
var text2 = E('text2'); // example of Element stored in variable
E('btn').onclick = function(){
text2.innerHTML = E('myText').value;
}
}
//]]>
I would recommend using a library like jQuery to do this. It would simplify the event handling and dom manipulation. None the less, I will include vanilla JS and jQuery examples.
Assuming the HTML in the body looks like this:
<form>
<input id="myText" type="text" placeholder="Enter Name Here">
<br>
<input type="submit" id="myButton">
</form>
<div id="text2"></div>
The Vanilla JS example:
//Get reference to button
var myButton = document.getElementById('myButton');
//listen for click event and handle click with callback
myButton.addEventListener('click', function(e){
e.preventDefault(); //stop page request
//grab div and input reference
var myText = document.getElementById("myText");
var myDiv = document.getElementById("text2");
//set div with input text
myDiv.innerHTML = myText.value;
});
When possible avoid using inline onclick property, this can make your code more manageable in the long run.
This is the jQuery Version:
//Handles button click
$('#myButton').click(function(e){
e.preventDefault(); //stop page request
var myText = $('#myText').val(); //gets input value
$('#text2').html(myText); //sets div to input value
});
The jQuery example assumes that you have/are adding the library in a script tag.

Showing more form inputs on selection

So I am trying to create a bit of a listing page. So basically they enter the details about a product. A button below says "Add another product".
How would I go about making it so when someone clicks the button, it shows another set of html <input>?
you can use jQuery to append an input on click:
HTML
<div class="container">
<input type="text"/>
</div>
<button>ADD</button>
JS
$("button").click(function(){
$(".container").append("<input type='text'/>");
});
EXAMPLE 1
OR
with plain javascript:
HTML
<div id="container">
<input type="text"/>
</div>
<button onclick="add()">ADD</button>
JS
function add(){
var newInput = document.createElement("input");
newInput.type = "text";
document.getElementById("container").appendChild(newInput);
}

how to read input from text input field and put input into div

I am trying to run this code.
the code should take a string as input and put that input to a div and calculate the width of the div.
here is code i have used.
<!DOCTYPE html>
<html>
<head>
<script src="http://code.jquery.com/jquery-1.9.1.js"></script>
</head>
<body>
<input type="text" value="" name="input">
<input type="submit" value="submit" name="submit">
<script>
var elem = '<div id="divitem" style="width:auto;"></div>';
$('body').append($(elem));
$("submit").click(function () {
var text = $(this).text();
value= $("input").val(text);
alert(value);
});
</script>
</body>
</html>
but i am not getting any output. how to do this?
please help me.
Try this paps!
Demo
This is similar to your problem.
HTML
<div id="container">
<input type="text" value="" id="inputtext">
<input type="button" value="submit" id="submit">
</div>
Script
$(function(){
var elem = '<span id="divitem"></span>';
$('#container').append($(elem));
$("#submit").click(function () {
$('#divitem').html($('#inputtext').val());
alert($('#divitem').width());
});
});
Here's a fiddle
To obtain value from a text field you need to use this,
$('input[name="input"]').val();
and not .text()
To answer your second question, you need to use this
$('#divitem').attr('style');
or
$('#divitem').attr('width');
The problem is here:
$("submit").click(function () {
var text = $(this).text();
value= $("input").val(text);
alert(value);
});
$(this) refers to the element that you select, which is the submit button.
You should replace the first line of the function with
$('input[name="input"]').text();
Finally, setting the html content of the div, will be done this way:
elem.html(test);
Hope this helps. Have a great day.
I have created a jsFiddle for your question http://jsfiddle.net/N4zFZ/ in JavaScript
You can calculate width by
`var width = $('#divId').attr('width');`

Add a string of text into an input field when user clicks a button

Basically just trying to add text to an input field that already contains a value.. the trigger being a button..
Before we click button, form field would look like.. (user inputted some data)
[This is some text]
(Button)
After clicking button, field would look like.. (we add after clicking to the current value)
[This is some text after clicking]
(Button)
Trying to accomplish using javascript only..
Example for you to work from
HTML:
<input type="text" value="This is some text" id="text" style="width: 150px;" />
<br />
<input type="button" value="Click Me" id="button" />​
jQuery:
<script type="text/javascript">
$(function () {
$('#button').on('click', function () {
var text = $('#text');
text.val(text.val() + ' after clicking');
});
});
<script>
Javascript
<script type="text/javascript">
document.getElementById("button").addEventListener('click', function () {
var text = document.getElementById('text');
text.value += ' after clicking';
});
</script>
Working jQuery example: http://jsfiddle.net/geMtZ/
​
this will do it with just javascript - you can also put the function in a .js file and call it with onclick
//button
<div onclick="
document.forms['name_of_the_form']['name_of_the_input'].value += 'text you want to add to it'"
>button</div>
Here it is:
http://jsfiddle.net/tQyvp/
Here's the code if you don't like going to jsfiddle:
html
<input id="myinputfield" value="This is some text" type="button">​
Javascript:
$('body').on('click', '#myinputfield', function(){
var textField = $('#myinputfield');
textField.val(textField.val()+' after clicking')
});​
HTML
<form>
<input id="myinputfield" value="This is some text">
<br>
<button onclick="text()">Click me!</button>​
</form>
Javascript
const myinputfield = document.querySelector("#myinputfield");
function text() {
myinputfield.value = myinputfield.value + "after clicking";
}
I know this question is almost ten years old but this answer does not use jquery so it may be useful to others.
