Show hide jquery

With the development of the Internet, front-end development technologies are becoming more and more diverse. Among them, jQuery is one of the very famous front-end development technologies. It can be used to implement many functions, such as form validation, dynamic modification of page content, animation effects, etc. In this article, I will introduce you to a very important function in jQuery - the display and hiding of elements.

The show and hide methods in jQuery

In jQuery, elements are shown and hidden respectively through the show and hide methods. These two methods are very easy to use and only require a simple statement to complete. Here is an example:

$( "#element" ).show(); // 显示元素
$( "#element" ).hide(); // 隐藏元素

In the above example, we pass the element's ID to the jQuery selector, and then use the show and hide methods respectively to control the display and hiding of the element.

In addition, the show and hide methods can also accept an optional parameter to control the time of the animation. By default, jQuery does not use animation effects when controlling the display and hiding of elements. However, if you want the display and hiding of elements to have some animation effect, you can achieve this by setting the animation time. Here is an example:

$( "#element" ).show( "slow" ); // 显示元素，并带有动画效果
$( "#element" ).hide( "fast" ); // 隐藏元素，并带有动画效果

In the above example, we pass the animation effect time as a parameter to the show and hide methods. In this example, we use the two strings "slow" and "fast" as time parameters. These strings represent different animation speeds. By default, "slow" represents 600 milliseconds and "fast" represents 200 milliseconds.

Use the toggle method to switch the display and hiding of elements

In addition to the show and hide methods, jQuery also provides a very useful method - the toggle method. This method toggles between showing and hiding the element. Here is an example:

$( "#element" ).toggle(); // 切换元素的显示状态

In the above example, we called the toggle method to switch the display state of the element. If the element is currently hidden, the element will be displayed after calling the toggle method. On the other hand, if the element is currently displayed, the element will be hidden after calling the toggle method.

In addition, the toggle method can also accept an optional parameter and be used to control the effect of the animation. Like the show and hide methods, you can set the animation time to show and hide elements with some animation effects. Here is an example:

$( "#element" ).toggle( "slow" ); // 切换元素的显示状态，并带有动画效果

Summary

In this article, we introduced the methods used to control the display and hiding of elements in jQuery: show, hide, toggle. These methods are very easy to use, just pass the ID of the element. In addition, these methods can accept an optional parameter to control the animation effect. If you want to animate the display and hiding of elements, you can do so by setting the animation time.
