display the limit of input char

[SAN CAZIANO]

how can I have on the right of an input field the number of the char that we
can put on it (when it's length is changed this number must changed itself:
perhaps onkeypress event)???

thanks , but there is a method to display the limit in a label and if i
assign a value to the input field, when i load the page the limt char is not
right, because I have to write on the input field to refresh the limit value
