The onblur event activates when an element loses focus. The event can be specified as a JavaScript expression or the name of a JavaScript function.
If an expression is used, the JavaScript keyword this refers to the element that lost focus.
If the name of a function is used, the function will receive 2 parameters when called:
The browser event object
A reference to the element that lost focus
Example:
The following would draw a red border around the element with focus. When the element loses focus, the border is removed.
onfocus: this.style.border = "1px solid red";
onblur: this.style.border = "";
