Question

What is the syntax to assign a speed to each fade?

 function fadeIn()
{
   $(this).fadeIn( fadeOut );
}

function fadeOut()
{
   $(this).fadeOut( fadeIn );
}

fadeIn.call($("#myImage"));

Answer 1

The syntax is to pass in a number representing the number of miliseconds the effect will last, like this:

function fadeIn() {
   $(this).fadeIn(1000); // 1 second
}

You can also create a variable to store the number

var length = 1000;

function fadeIn() {
   $(this).fadeIn(length);
}
