jQuery Effects – Hide and Show

jQuery hide() and show()

With jQuery, you can hide and show HTML elements with the hide() and show() methods:

$("#hide").click(function(){
  $("p").hide();
});

$("#show").click(function(){
  $("p").show();
});

Syntax:

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

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

The optional speed parameter specifies the speed of the hiding/showing, and can take the following values: “slow”, “fast”, or milliseconds.

The optional callback parameter is a function to be executed after the hide() or show() method completes (you will learn more about callback functions in a later chapter).

The following example demonstrates the speed parameter with hide():

$("button").click(function(){
  $("p").hide(1000);
});

jQuery toggle()

You can also toggle between hiding and showing an element with the toggle() method.

Shown elements are hidden and hidden elements are shown:

$("button").click(function(){
  $("p").toggle();
});

Syntax:

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

The optional speed parameter can take the following values: “slow”, “fast”, or milliseconds.
