A read-only text field is a classic example for using the blur() method. The algorithm to create such a field is very simple. When the user explicitly gives focus to a field in order to write in it, an event handler (onFocus) invokes the blur() method to instantly remove the focus. Here is a read-only text field example:

<FORM>
<INPUT TYPE="text" NAME="myField" VALUE="Have you checked docjs.com?" onFocus="this.blur()" SIZE="40">
</FORM>
