Pass field values to Java script function

Hi all,

 

I have created a VF Page.. I need to validate the values entering in a text box.

 

I should not enter more than three characters in that text box.

 

If i enter a value in text box, that value should pass to a java script function and that should validate and throw a error.

 

Please give me a sample code...
