Jquery limit text in input box

Question

I want to limit number of chars in input text field.

Code I'm using:

function limitText(field, maxChar){
    if ($(field).val().length > maxChar){
       $(field).val($(field).val().substr(0, maxChar));
    }
}

Event is onkeyup. When I type some text in input field cursor stays on the end of text but focus is backed on start of the text so I can't see cursor.

What can be a problem.

Browser is FF, on IE and chrome it is working correctly

Answer 1

you can also do it like this:

<input type="text" name="usrname" maxlength="10" />

to achieve this with jQuery, you can do this:

function limitText(field, maxChar){
    $(field).attr('maxlength',maxChar);
}
