Menu
I have a textarea that is being dynamically reloaded as user input is being sent in. It refreshes itself every couple seconds. When the amount of text in this textarea exceeds the size of the textarea, a scroll bar appears. However the scroll bar isn't really usable because if you start scrolling down, a couple seconds later the textarea refreshes and brings the scroll bar right back up to the top. I want to set the scroll bar to by default show the bottom most text. Anyone have an idea of how to do so?

That'd be :: messageBody. lastChild. scrollIntoView(); //for the initial scroll to bottom position. p.s.: After the page load, this command should be called by your message handler on message update.
The first one is with javascript: set the scrollTop property of the scrollable element (e.g. document. body. scrollTop = 1000; ). The second is setting the link to point to a specific id in the page e.g.
scroll(function() { if($(window). scrollTop() + window. innerHeight == $(document). height()) { alert("bottom!"); } });
the easiest way would be to use "readonly" instead. another way would be to use a fixed-height div will overflow:scroll that looks like a textarea but isn't.
pretty simple, in vanilla javascript:
var textarea = document.getElementById('textarea_id'); textarea.scrollTop = textarea.scrollHeight; You can use this with jQuery
$(document).ready(function(){ var $textarea = $('#textarea_id'); $textarea.scrollTop($textarea[0].scrollHeight); }); If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
