In Javascript, I want to execute my function whenever the textbox loses its focus. What's the easiest way to do this?

So you have two options
OnFocousOut
<input type="text"
name="input"
value="Lorem"
onfocusout="yourFunction();" />
or OnBlur
<input type="text" onblur="myFunction()">

In most of the case I don't use onblur I use onchange method because it will indicate user only if user change the value of text box so i think it's user friendly.
Easiest method is to add your javascript in html tag
<input type = "text" onchange = "yourFunction()">
but this is not a good practice. Write your javascript in external file.
