Resize text area to fit all text on load jquery

Solution 1:

Try this

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

DEMO

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);

DEMO

UPDATE FOR MULTIPLE TEXTAREAS

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

Solution 2:

This worked for me; it loops through all "textarea" elements on page Ready, and set their height.

$(function () {
    $("textarea").each(function () {
        this.style.height = (this.scrollHeight+10)+'px';
    });
});

You can also combine it with an auto-expand function, to make it fully dynamic while writing as well:

function autoresize(textarea) {
    textarea.style.height = '0px';     //Reset height, so that it not only grows but also shrinks
    textarea.style.height = (textarea.scrollHeight+10) + 'px';    //Set new height
}

and call that from an "keyup" event or through jQuery:

$('.autosize').keyup(function () {
    autoresize(this);
});

Note how I am adding 10px to the scroll height: here you can adjust the amount of space you would like the bottom of the text area to give the user.

Hope that helps someone. :)

Edit: Changed answer according to @Mariannes comment.

Solution 3:

you can use this. It works for me.

$('#content').on('change keyup keydown paste cut', 'textarea', function () {
        $(this).height(0).height(this.scrollHeight);
    }).find('textarea').change();

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<div id="content">
  <textarea>How about it</textarea><br />
  <textarea>111111
222222
333333
444444
555555
666666</textarea>
</div>

Solution 4:

You mentioned there are multiple textboxes. This code will set the height of each textarea according to its own contents.

$(document).ready( function( ) {

    $("textarea").each( function( i, el ) {
        $(el).height( el.scrollHeight );
    });

});

Solution 5:

Alternatively, you could use an editable div in HTML 5.
