Say I have a <textarea> element in my HTML, and I have a send button. When you press that send button, the text in the <textarea> element should appear on the screen.
I tried putting this JavaScript code in my head section:
<script>
function displayText(element, change_to) {
document.getElementById(element).innerHTML = document.getElementById(change_to).innerHTML
}
</script>
And this is the body section:
<body>
<p id="msg"></p>
<textarea id="enterMsg"></textarea>
<button id="sendButton" onclick="displayText('msg', 'enterMsg')">Send</button>
</body>
But that didn't work.
You should use value property for the textarea element. I will also suggest you use innerText or textContent if the value is plain text (not htmlString):
<script>
function displayText(element, change_to) {
document.getElementById(element).textContent = document.getElementById(change_to).value
}
</script>
<body>
<p id="msg"></p>
<textarea id="enterMsg"></textarea>
<button id="sendButton" onclick="displayText('msg', 'enterMsg')">Send</button>
</body>
textarea don't have innerHTML, you should use .value instead

it changes for about a second and returns to the previous text.The "Loading..." line has to change into "hi, Please click the next text box to see more instructions!".
I have tried it latest chrome and Edge browsers.
function greetMe() {
var yourName = document.getElementById("textbox").value;
info1 = "hi, Please click the next text box to see more instructions!"
document.getElementById("textToChange").innerHTML = info1
}
#myForm {
float: left;
width: 30%
}
#myformInfo {
}
<!DOCTYPE html>
<html>
<head>
</head>
<body>
<h1>HEllO ThERE!</h1>
<div id="myForm"><form >
<input id="textbox" placeholder="Your name">
<button onclick="greetMe()">click!</button>
<br><br>
<input id="">
</div></form>
<div id="myFormSteps">
<p id="textToChange">
<script>var info1 = "Loading..."
document.write(info1)
</script>
</p>
</div>
</body>
</html>
It's probably because you haven't set the type attribute for your button. A button's default type is submit. Try adding the attribute type="button" to your <button>.
When you click the button your form is submitting and the page is reloading - that's why it returning to its initial state. To stop this happening pass in event as a parameter to the function and then use that argument in the function with preventDefault():
HTML
<button onclick="greetMe(event);">click!</button>
JS
function greetMe(e) {
e.preventDefault();
// ...
}
As an aside it's better is to remove your inline JS and use an event listener instead.
var button = document.querySelector('button');
button.addEventListener('click', greetMe, false);
I'm rather new to programming, but let's keep going. My goal is to create a button that when pressed it will print out text. If you press a second time, it will print out text below the original snippet and so on. Basically, if you keep clicking the button you'll get text repeated a number of times below each other. Currently I've achieved a button that when pressed it prints out text. Press it again and it does nothing. Here's the code I used:
<input type="button" value="Duplicate Text" onclick="dup()"/>
<p id="clone"></p>
<script>
function dup() {document.getElementById("clone").innerHTML="Text";}
</script>
I'm sure I've done something wrong. Thanks a million.
If you're convinced that it should work, try it. It WILL print out text, but then when you do it a second time, it does nothing.
The below example is self explanatory
DEMO http://jsfiddle.net/YzqML/
<script>
function myFunction() {
var h = document.createElement("p");
var t = document.createTextNode("Hello World");
h.appendChild(t);
document.body.appendChild(h);
}
</script>
<p id="demo">Click the button to make more text within a "p" tag.</p>
<button onclick="myFunction()">Try it</button>
Another example with checkbox and label
DEMO http://jsfiddle.net/YzqML/1/
<script>
function myFunction() {
var div = document.getElementById('myItems'),
clone = div.cloneNode(true);
document.body.appendChild(clone);
}
</script>
<div id="myItems">
<label>My Label</label>
<input type="checkbox" />
</div>
<p id="demo">Click the button to clone the above items</p>
<button onclick="myFunction()">Try it</button>
You can create new elements and append them to the DOM, like this:
function display(msg) {
var p = document.createElement('p');
p.innerHTML = String(msg);
document.body.appendChild(p);
}
Each time you call the display function, the string you give it is added to a new paragraph (p element) on the page, which is added to the bottom of the body.
I note a jquery tag in your question , so you can do this :
<input type="button" value="Duplicate Text" onclick="$('<p />').appendTo('body')"/>
DEMO :

Copy paste this code in an html file and run in a browser. If you could include Jquery, then more simpler the code would be.
<html>
<head>
<script>
function myFunction() {
var h = document.createElement("p");
var t = document.createTextNode("Hello World");
h.appendChild(t);
document.body.appendChild(h);
}
</script>
</head>
<body>
<p id="demo">Click the button to make more text within a "p" tag.</p>
<button onclick="myFunction()">Try it</button>
</body>
</html>
I want to type in text in a text field, press a button, and the text of a paragraph will change. What would I need to do for this to happen and is there an easier way to do it other than javascript?
Since I didn't know what I needed to do, here's the code I originally had:
<html>
<head>
<title>Moving Text</title>
<link rel="stylesheet" type="text/css" href="stlye.css">
</head>
<body>
<div id="text">
<p id="new">new text</p>
Main News:<input type="text" name="update"><br>
<input type="button" value="Update" onClick="update();">
<script type="text/javascript">
function update(){
document.getElementById('new').innerHTML = 'Update';
}
</script>
</div>
</body>
I'm pretty sure it's wrong or way off. Any suggestions?
HTML:
<p id="your_paragraph">This text will change, after clicking the button.</p>
Main News: <input type="text" id="theText" />
<input type="button" id="btn" value="Update" />
JavaScript:
var p = document.getElementById('your_paragraph');
var btn = document.getElementById('btn');
var txt = document.getElementById('theText');
btn.onclick = function(){
p.textContent = txt.value;
};

No, you'll need to use javascript. Without an example of your markup nobody will be able to provide you a specific example, but here's a general one using the jQuery library.
// get the textarea, watch for change, paste, and keyup events
$('textarea').on('change paste keyup', function(){
// Store the text field as a variable, get it's value
var thiis = $(this),
value = thiis.val();
// replace the paragraph's content with the textrea's value
$('p').html(value);
});
Hey so I'm trying to use jTicker to say messages that can react to user input.
The way jTicker works, it affects text between html element tags.
In this example, I'm trying to use jQuery to modify the text between a certain set of tags that is being tickered? by jTicker. The problem is that whenever I try to change the text, jTicker only uses the text that was between the tags when the page first loaded and not the new text.
How can I fix this code so that the text that jTicker is affecting can be changed on the fly?
Javascript:
<script src="jquery.jticker.js"></script>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<script>
$(document).ready(function() {
$("#messageId").ticker({
rate: 40,
delay: 900,
transition: "fade",
});
$(".stop").click(function(){
$("#messageId").trigger("stop");
return false;
});
$(".play").click(function(){
$("#messageId").trigger("play");
return false;
});
});
function test() {
$('#theMessage').text('New text!');
}
</script>
Html:
<body>
<div id="messageId">
<p id="theMessage">Old text</p>
</div>
<div>
<input type="button" value="Test"
class="play" onClick="test();" />
</div>
</body>
function test() {
$('#theMessage').text($("#messageId").text());
}
I'm trying a very basic example of creating a div inside an already existing div.
It doesn't seem to be working when I use:
document.getElementbyId('lc').appendChild(element)
but works fine when I do this:
document.body.appendChild(element)
Do I need to add windows.onload function? Though it doesn't work even then!
HTML code:
<body>
<input id="filter" type="text" placeholder="Enter your filter text here.." onkeyup = "test()" />
<div id="lc">
</div>
</body>
JS code:
function test()
{
var element = document.createElement("div");
element.appendChild(document.createTextNode('The man who mistook his wife for a hat'));
document.getElementbyId('lc').appendChild(element);
//document.body.appendChild(element);
}
Your code works well you just mistyped this line of code:
document.getElementbyId('lc').appendChild(element);
change it with this: (The "B" should be capitalized.)
document.getElementById('lc').appendChild(element);
HERE IS MY EXAMPLE:
<html>
<head>
<script>
function test() {
var element = document.createElement("div");
element.appendChild(document.createTextNode('The man who mistook his wife for a hat'));
document.getElementById('lc').appendChild(element);
}
</script>
</head>
<body>
<input id="filter" type="text" placeholder="Enter your filter text here.." onkeyup = "test()" />
<div id="lc" style="background: blue; height: 150px; width: 150px;
}" onclick="test();">
</div>
</body>
</html>
'b' should be in capital letter in document.getElementById modified code jsfiddle
function test()
{
var element = document.createElement("div");
element.appendChild(document.createTextNode('The man who mistook his wife for a hat'));
document.getElementById('lc').appendChild(element);
//document.body.appendChild(element);
}
Yes, you either need to do this onload or in a <script> tag after the closing </body> tag, when the lc element is already found in the document's DOM tree.
