How to show hidden controls in jquery

jQuery is an excellent JavaScript library. It provides us with many convenient and quick operation methods, including displaying and hiding controls. This article will introduce how to display and hide controls through jQuery.

1. How to hide controls

1. Use the hide() method

The hide() method is the most basic method of hiding controls provided by jQuery. It can hide any HTML element. For example, suppose you have a button:

Click me

To hide this button, just call the hide() method:

$("#myButton").hide();

This will make the button no longer appear on the page.

2. Use the fadeOut() method

The fadeOut() method will gradually reduce the opacity of the element until the element is completely hidden. You can control its speed and time by setting the parameters of the fadeOut() method.

For example:

$("#myButton").fadeOut(1000);

This will make the button disappear in 1 second.

3. Use the slideUp() method

The slideUp() method can slide the element upward until it is completely hidden. Like the fadeOut() method, you can control its speed and time by setting parameters.

For example:

$("#myButton").slideUp(1000);

This will make the button slide up and disappear within 1 second.

2. How to display controls

1. Use the show() method

click me

To show For this button, you only need to call the show() method:

$("#myButton").show();

This will make the button re-display on the page.

2. Use the fadeIn() method

The fadeIn() method can make an element from opaque to fully visible, which is the opposite of the fadeOut() method. Its speed and time can also be controlled by setting parameters.

For example:

$("#myButton").fadeIn(1000);

This will make the button go from transparent to fully visible in 1 second.

3. Use the slideDown() method

The slideDown() method can slide the element down until it is completely visible. Like the fadeIn() method, you can control its speed and time by setting parameters.

$("#myButton").slideDown(1000);
