How to get the height of the text inside of a textarea

Question

I have a textarea with the the text Hello World. I would like to get the height of this text.

I\'ve tried to use:

var eleme         


        

Answer 1

In jQuery there is no scrollHeight, so it needs a little workaround. the solution would be:

var areaheight=$("textarea#element")[0].scrollHeight;
$("#element").height(areaheight);

or shorter:

$("#element").height($("#element")[0].scrollHeight)
