Question

How can I get the length of text entered in a textbox using jQuery?

Answer 1

If your textbox has an id attribute of "mytextbox", then you can get the length like this:

var myLength = $("#mytextbox").val().length;

• $("#mytextbox") finds the textbox by its id.
• .val() gets the value of the input element entered by the user, which is a string.
• .length gets the number of characters in the string.
