I want to take the information typed into a text field and display it in a paragraph elsewhere on the page. Basically, exactly what is happening below as I'm type this (go to post a question and start typing in the main text box and you'll see what I mean).
Any idea how to do this? The page has so much JavaScript on it I can't find how they did it.
I think you are looking for this.
Here is how your html should look like:
<textarea id="txt" style="width:600px; height:200px;"></textarea>
<p id="preview"></p>
And jQuery:
$(function(){
$('#txt').keyup(function(){
$('#preview').text($(this).val());
});
});
This grabs the value of textarea
on its keyup
event and later the paragraph's text is changed (text()
method) with that of textarea
$(this).val()
.
