jQuery Callback Functions

A callback function is executed after the current animation is 100% finished.

jQuery Callback Functions

JavaScript statements are executed line by line. However, with animations, the next line of code can be run even though the animation is not finished. This can create errors.

To prevent this, you can create a callback function.

A callback function is executed after the current animation (effect) is finished.

jQuery Callback Example

Typical syntax: $(selector).hide(speed,callback)

The callback parameter is a function to be executed after the hide effect is completed:

Example with Callback

$("p").hide(1000,function(){
  alert("The paragraph is now hidden");
});

Try it yourself »

Without a callback parameter, the alert box is displayed before the hide effect is completed:

Example without Callback

$("p").hide(1000);
alert("The paragraph is now hidden");
