How to check length in jQuery for textarea?

In this article, I will show you textarea character count in jQuery. The easiest way to get character counter is $(“#your_textarea”). val().length in jQuery.

Example:

if ($("#txtcomment-0").val().length > 0) {

//do your stuff

alert($("#txtcomment-0").val().length);

            }

Here, I needed for commenting system to check the user input character count is greater than I allowed saving.

Note: If you want to trim the spaces at the beginning and end of the value by the following way,

if ($("#txtcomment-0").val().trim().length > 0) {

//do your stuff

            }

Output:

Showing alert the input count using jQuery length property.
