jquery callback()

As we know that JavaScript statements are executed line by line. But, if the effects are applied, the next line of code can be run even before the finishing of the current effect which can create errors. For this reason, we use callback functions.

A callback function is executed after finishing of the current effect

Syntax

$(selector).effect(speed,callback);

Example

$("button").click(function(){
  $("li").hide("slow", function(){
    alert("Sorry! The list is hidden");
  });
});
