Today we will be seeing a javascript which will help us to show how many characters are remaining for a textbox or textarea,As soon as the user starts typing in a textbox or textarea, then we will show how many characters are remaining for entering into the textbox.

Here we are creating a simple textbox, and we are specifying the "maxlength" of the textbox to 20.

And "onKeyUp" event of the textbox we are calling a javascript function "countCharacters()".

we will be writing a standard function which accepts only some parameters and rest of the processing will be done in the function.

To this function we have to pass 3 parameters
1) id of the span - where counter will be shown when user types something
2) max_chars - length of the textarea which we specified in maxlength="20"
3) myelement - the id of the textbox where user types text

The function is as below

Now you can use this function anywhere, without a need to modify this function.

The full code to try out is here
