Does anyone know how to make a textarea shrinkwrap the text inside on blur? The default number of columns is 10 or 15 and I want the textarea to adjust its width based on the text content.
I have tried the following code:
$('textarea').on('blur', function() {
var textAreaWidth = $(this).val().length;
$(this).attr('cols', 'textAreaWidth');
});
However, this solution is not ideal. I am looking for a better way to achieve this. Any ideas?
If you only want to reduce the size, make sure to check if the value is less than 20 and then decrease the number of columns. Give this a try:
<textarea rows="2" cols="20"></textarea>
$('textarea').on('blur', function() {
var textAreaWidth = $(this).val().length;
if (textAreaWidth < 20) {
$(this).attr('cols', textAreaWidth);
}
$('textarea').on('keypress', function() {
$(this).attr('cols', '20');
});
});
Make sure to eliminate the single quotes surrounding 'textAreaWidth' within
$(this).attr('cols', 'textAreaWidth');'textAreaWidth' is a variable and should not be enclosed in quotes.
$('input').on('focus change', function() {
$(this).attr('size', $(this).val().length);
});
Watch as it dynamically adjusts its size based on your input.
