javascript - Resize text area to fit all text on load jquery

Question

I understand there has been a lot of discussion on this but I have yet to find a solution to fix my needs. Basically I need to autogrow a text area not when you type but on load. I am pulling in content from a database and dependant on the user's settings an overlay is produced over the text area, but upon doing this the text areas are not scrollable therefore I need to autosize these to show all the text.

I have tried scrollHeight but this is not working great as there are multiple text boxes on the screen

Thanks

Answer 1

Try this

$("textarea").height( $("textarea")[0].scrollHeight );

UPDATE

As a hack to make it work in older IE-s just add a really short delay before executing it

window.setTimeout( function() {
    $("textarea").height( $("textarea")[0].scrollHeight );
}, 1);?

UPDATE FOR MULTIPLE TEXTAREAS

$("textarea").each(function(textarea) {
    $(this).height( $(this)[0].scrollHeight );
});
